KPop Demon Hunters (Western Animation)
For the fans.note 
We are Hunters, voices strong
Slaying demons with our song
Fix the world and make it right
When darkness finally meets the light.
The Demon Hunters' Mantra

KPop Demon Hunters is a 2025 Animated Musical Urban Fantasy action film directed by Maggie Kang and Chris Appelhans and produced by Sony Pictures Animation for Netflix. It was released on Netflix on June 20, 2025.

The plot follows the K-Pop Girl Group HUNTR/X (pronounced "Huntrix"), consisting of Rumi (Arden Cho), Mira (May Hong), and Zoey (Ji-young Yoo), who, unbeknownst to their fans and the public at large, are the latest in an ancient line of musical warriors called Hunters, who protect the world from demons and draw power from their fans to sustain a mystical barrier, the Honmoon, that can seal the demons away.

Now they face their biggest threat: a band of demons masquerading as a rival Boy Band, the Saja Boys, led by Jinu (Ahn Hyo-seop), who seek to steal HUNTR/X's fans, weaken the Honmoon, and allow a legion of demons to invade the world. Can the HUNTR/X trio stop the Saja Boys before they bring about a greater, soul-stealing threat? Or will their own personal demons undo them first?

Supporting roles include Ken Jeong as HUNTR/X manager Bobby, Kim Yunjin as HUNTR/X mentor Celine, and Lee Byung-hun as the Demon King Gwi-Ma.

A sing-along version was given a limited theatrical release on August 23-24, 2025 before it was released on Netflix on August 25, 2025, with a second theatrical run released on October 31-November 2, 2025.

"Happy tropes, happy Honmoon!"

    open/close all folders 

    Tropes A to C 
  • Actor Allusion:
    • When Rumi first lays eyes on Jinu (voiced by Ahn Hyo-seop), MeloMance’s "Love, Maybe" starts playing. "Love, Maybe" was written for and featured heavily on the soundtrack of Business Proposal, where Ahn played the protagonist and male romantic lead.
    • After his role as Dr. Han from The Good Doctor gained memetic popularity in the early 2020s, Daniel Dae Kim plays another doctor, who runs a clinic named "Han".
  • Actually Quite Catchy:
  • Advertised Extra: Besides Jinu, the members of the Saja Boys don’t get much focus or character development.
  • Advertising by Association: The official trailer says how this is from "Sony Pictures Animation, the studio that brought you Spider-Man: Across the Spider-Verse.
  • Affectionate Parody: The film is an overall celebration of KPop and modern Korean media, but it still takes affectionate digs at the subject matter:
    • The Saja Boys are a pastiche of every KPop boy band archetype dialed up to eleven.
    • The Meet Cute sequence between Rumi and Jinu is ripped straight from a KDrama; from the slow-motion fall, the romantic haze, and even the ending theme from Business Proposal playing in the background... right before Jinu dismissively tells Rumi to watch where she's going.
  • All Girls Want Bad Boys:
    • HUNTR/X still find the Saja Boys attractive even after learning that they’re demons. Zoey in particular struggles not to drool over them, but it’s Rumi who ends up actually developing a connection with one of them.
    • Deliberately invoked during the climax, where the Saja Boys drop their bubblegum vestige and reveal their demonic nature to their adoring fans, who think it's just All Part of the Show and happily eat up their darker aesthetic while getting their souls drained for their adoration.
  • Alliterative Name: "Sunlight Sisters" is the group name of the Demon Hunter trio directly preceding HUNTR/X.
  • All Part of the Show:
    • In their performance for "How It's Done", HUNTR/X skydive onto the stage in pursuit of demons, then slay them in front of their audience of fans. The fans naturally assume it's all special effects.
    • The Saja Boys use this trope to get away with using magic to enhance their shows, and during their "Your Idol" concert they drop their human disguises entirely and appear onstage in their true demonic forms. When Gwi-Ma appears before the audience he initially seems like part of the special effects.
  • All Take and No Give: In the lyrics of "Soda Pop," the singer only talks about what his love interest could do for him, without mentioning anything he could do for her, with lines like "you could be everything that I need" and "I need you to need me, I'm empty, you feed me." Of course, this only reinforces that the song's purpose is to pull in fans for the demon boy band Saja Boys so their souls can be eaten.
  • All There in the Script:
    • The 2D animated credits show Celine Dual Wielding cyan and purple daggers, implying them as her preferred weapons when she was still an active demon hunter.
    • Abby Saja is referred to as "Abs Saja" in the credits.
    • In the section of the end credits which chronologically list the featured music tracks, it's revealed that "Jinu's Lament" is the official title of what Jinu sang to mock Gwi-Ma moments after "How It's Done".
  • Always Chaotic Evil: Zigzagged. The hunters operate under the assumption that all demons are monsters who must be killed or sealed since they're too dangerous to coexist with humans. However, a few wrinkles show up in this conviction. Rumi is a half-demon who is most of the time just like a human being, but her demon side starts to exert itself more when she feels shame. Jinu, who used to be a human who made a Deal with the Devil, explains that demons are driven to evil by the voice of Gwi-Ma in their head, and proves with a Heroic Sacrifice that he can turn away from evil. But when Rumi tries asking another demon if they're being forced to fight for Gwi-Ma, the demon just snarls at her, suggesting the "pure" humanoid demons are indeed monstrous (or at least have lost any and all humanity they may have once had; this might even be what Jinu is asking for by requesting that Gwi-Ma remove his human memories). As for the animal demons that accompany Jinu, they seem to have no interest in harming humans, and appear in the human world after the creation of the new Honmoon, implying that while most demons have been sealed, some are permitted to cross the barrier if they're not a threat to humankind.
  • Ambiguous Situation:
    • It’s never explained how Rumi was conceived. All we know is that she was a human/demon hybrid from birth and her late mother was human, but we know nothing about her father. Was he a natural demon, or was he a former human like Jinu? Where is he? Is he dead or alive? We just don’t know.
    • At the fan meet event, Mira, Romance, and Abby all form the In-Universe fan-ship named "Miromabby", but it's unclear whether the fans ship them as a Love Triangle or a One True Threesome. By contrast, the "Zoeystery" ship also involves the trio of Zoey, Mystery, and Baby Saja, but the artwork makes it clear that the in-universe fans ship Zoey and Mystery together while depicting Baby as their child.
    • Are there demons and/or Hunters in other countries besides Korea? On one hand, the whole film takes place in Korea, there is no mention of other Hunters besides the three per generation, and it’s unlikely that pre-commercial-flight generations would have been able to crisscross the globe for their duties. On the other hand, the characters talk of protecting “the world”, and they start the film wrapping up a world tour, which would be pretty irresponsible if there were no demons elsewhere.
    • During the Darkest Hour, there's ambiguity over the Internal Reveal and the subsequent falling out of HUNTR/X: was it because Zoey and Mira are disgusted that their best friend turned out to be a demon they've been trained to kill on sight all their lives, or was it more because Zoey and Mira are disgusted that Rumi would lie to them instead of telling them? There's some hints that Zoey and Mira would have accepted Rumi, but the point is moot and they're all split apart when it happens.
    • The ending is vague about how much of the status quo has changed since the climax. Rumi has started wearing her demon patterns out in the open. Merchandise for the Saja Boys is seen in the trash, but it's left unsaid whether the public knows that they were actually disguised demons. Derpy Tiger and Sussie are seen in the city, showing that some demons can cross the new Honmoon (presumably if they're not dangerous), but it's unknown if any other demons have passed through as well. Given that much of the previous supernatural events were shown to be Invisible to Normals or assumed to be All Part of the Show, it's vague whether the populace knows now about HUNTR/X's true identities as demon hunters and of Rumi being part-demon.
    • Gwi-Ma is defeated in the final battle, but the ending is still ambiguous on whether he's completely gone for good or was simply sent back to the demon world. A new Honmoon was indeed created, but it's not the Golden Honmoon that was expected to keep him away forever. There's no acknowledgement of what happened to him after his last encounter with HUNTR/X.
  • And Starring: In the end credits, the cast list ends with: "With Daniel Dae Kim, With Ken Jeong, And Byung-hun Lee".
  • And the Adventure Continues: The protagonists are last seen greeting a group of young fans, but the camera leaves them to follow Sussie, who swoops over a district covered with Honmoon patterns and lands on Derpy. The two look over Seoul, underlining (because Derpy and Sussie are magical creatures) the fact that magic is still a part of the human world.
  • Animated Musical: Naturally since the characters are Magic Idol Singers who use Magic Music to fight demons. The movie is mostly a Diegetic Musical with the characters singing rehearsed musical numbers in universe, but there are a couple Musical World Hypotheses moments where Rumi sings her thoughts aloud when she’s alone in "Golden" and sings an improvised duet with Jinu in "Free". The final song "What It Sounds Like" is HUNTR/X singing a completely improvised song.
  • Animesque: The film sees the fully 3D characters revert to both simple comical anime expressions and more over the top, detailed expressions reminiscent to the art of Akira Toriyama. The ending credits also features all the characters in Super-Deformed style.
  • Answer Cut: In the teaser trailer, Mira turns down Bobby’s invitation to an exclusive resort, saying they already have plans. When he asks what they are, cut to her and Zoey collapsing happily on the couch with a tray of food.
  • Appearance Angst: When Jinu and Rumi first meet, he makes fun of her pajama pants. This is largely Played for Laughs, as the pants are pretty silly, but it's also subtle Foreshadowing of his unkind nature, as this is the only time in the whole movie that someone criticizes any of the Power Trio for their appearance.
  • Arc Words:
    • "For the fans." HUNTR/X loves their fans just as much as their fans love them.
    • "We are Hunters, voices strong, Slaying demons with our song." It's a part of the hymn passed down by the generations of demon hunters, it's heard several times throughout the film, and is mostly associated with Celine mentoring HUNTR/X. The lyrics of "Golden" also include the line "Cause we are hunters, voices strong and I know I'll believe". It even plays in the background while Rumi confronts Celine about her half-demon nature being exposed. It likewise summarizes the role of the heroes as both demon hunters and singers.
      • Relatedly, "We are Hunters, voices strong. Our faults and fears must never be seen." It's first said when Rumi reveals her vocal problems to Mira and Zoey, and they consider asking Celine, and then parrot this phrase as the advice they know she'd give. It comes up again when Mira says "I know our faults and fears must never be seen, but—" and chooses to open up to Rumi and Zoey about her own insecurities, and Zoey follows suit (but, most importantly, Rumi does not). Finally, after Rumi is exposed and her demon half appears to be taking over, Celine reinforces that "Our faults and fears must never be seen, it's the only way to protect the Honmoon." Rumi retorts that such a Honmoon isn't worth protecting, and at the climax, builds a new one with Mira and Zoey with the song "What It Sounds Like," all about accepting one's faults and fears instead of running from them or trying to hide them.
    • "No more hiding" and its variants are mostly associated with Rumi. The lyrics of "Golden" include the line "I'm done hiding, now I'm shining like I'm born to be." Rumi then says "No more hiding" when she starts opening up to Jinu on their second secret meeting, but she shouts it later when she confronts Celine during a dramatic scene and decides it's not worth hiding her demonic marks anymore.
    • "When darkness meets the light" and its variants are also reused a few times, it being the end of the hunters' hymn and the climactic high note of "How It's Done". The final lyric of "What It Sounds Like" is "When darkness meets the light, this is what it sounds like". Interestingly, the line can have a couple of different meanings: the one probably initially intended is that, when darkness meets the light, the light will banish the darkness. The second meaning could be about Rumi, and by extension everyone, accepting whatever darkness lies within, bringing it to meet the light and uniting them into a stronger whole by accepting all of what you are, but not permitting it to define you. On top of that, "Darkness" and "Light" could also describe Rumi's parents: a hunter fighting for the light against a demon of darkness. But it was this "Darkness" meeting this "Light" that birthed Rumi.
    • "Free." When Rumi tells Jinu about her plan to have him stay in the human world once the Honmoon is sealed, she adds that she'll be free of her demon patterns, while he'll be free of the voices in his head. "Free" is also the title of the duet Rumi and Jinu sing on the night before the Idol Awards. After said duet, Gwi-Ma taunts Jinu for believing that he could be free. Additionally, one of the lyrics of "Your Idol" is "I will make you free when you're all a part of me." Finally, when Jinu sacrifices himself to protect Rumi, she laments that she wanted to set him free, to which Jinu reassures her that she did.
  • Armor-Piercing Question:
    • After Rumi's patterns are publicly exposed, she argues with Jinu about whether or not demons can overcome their shame and despair through force of will. Her angry screams cause ripples in the Honmoon, to which Jinu dryly asks, "Listen to yourself. Is it working?" This sets off the start of Rumi's epiphany that ignoring one's inner demons isn't the effective way to battle them.
    • The Darkest Hour sees Gwi-Ma weaponising this to break and enthrall Mira, who just had her Family of Choice destroyed by the reveal that Rumi is apparently a demon traitor, and is, despite all appearances, is still broken up about her falling out with her real family:
      "You thought you found a family? You don't deserve one. You never have."
    • When Rumi goes to Celine for guidance after her half-demon form has been fully exposed, she realizes very quickly that Celine doesn't actually accept her demon heritage for what it is, seeing it only as something to be concealed and expurgated. In this moment where Rumi is desperate for consolation from her maternal figure, the fact that she is granted none for her biggest personal trauma causes her to realize that the Honmoon has been misguided in its efforts this whole time.
      Rumi: Why can't you look at me? WHY COULDN'T YOU LOVE ME!?
      Celine: [still not looking Rumi in the eye] I do!
      Rumi: ALL OF ME!!
  • Armor-Piercing Response: During their argument at the joint signing event, Rumi rants to Jinu about how she hates her patterns, demons and Gwi-Ma. Jinu responds that if hate was all it took to defeat Gwi-Ma, he would've done it a long time ago. Rumi noticeably treats him with less hostility throughout the rest of the movie after this.
  • Artistic License – Physics: During "How It's Done", HUNTR/X's private plane gets trashed by the demons and leaves HUNTR/X looking out of their literally cut in half plane, Looney Tunes style. Needless to say, the plane would not be capable of flying straight anymore and would nosedive out of control, not even accounting for explosive decompression.
  • As Long as There Is One Man: By the climax, Gwi-Ma has essentially won. However, Rumi can still raise her voice against him and make a new Honmoon.
  • Audience Participation Song: The In-Universe crowd continues singing "What It Sounds Like" when Jinu sacrifices himself and the HUNTR/X trio run towards Gwi-Ma.
  • Autobots, Rock Out!: Integrally woven into the story. Since the Hunters use music to stoke the positive energy needed to power the Honmoon, song and dance are critical to their fighting style. The opening narration features the original trio of Hunters singing traditional music to banish the demons attacking a village in a Big Damn Heroes moment, followed by a brief montage of Hunters through the decades as different styles of musical act. Then our introduction to HUNTR/X shows them breaking into song to defeat the demons that have hijacked their plane, before finishing "How It's Done" in front of their audience, charging the Honmoon to make it stronger against demon incursions. As the Saja Boys steal HUNTR/X's fans and weaken the Honmoon, HUNTR/X responds by hunting down the demons slipping through, and in the train fight, sing "Takedown" to fight the horde of demons and close the massive tear in Honmoon (this one is a subversion, as Rumi is having issues with the song, which causes the fight to briefly turn against HUNTR/X). During the Darkest Hour, Zoey worries that not having Rumi means their songs to combat Gwi-Ma will be ineffective, as they're three-part harmonies. Finally, at the climax, HUNTR/X sings "What It Sounds Like" to defeat Gwi-Ma's minions, break his hold over the humans, banish him back to the demon world, and build a new Honmoon after Gwi-Ma and the Saja Boys destroyed the old one.
  • Badass Boast: The lyrics of "How It's Done" are chock-full of this. For instance, Zoey raps, "Mirror, mirror on the phone, who's the baddest? Us, hello" while slaying a demon. Rumi also sings that HUNTR/X will make fear itself afraid to breathe while delivering the climactic high note.
  • Badass Creed: The hunter's mantra sums up exactly what they are doing and what they believe in.
    We are Hunters, voices strong
    Slaying demons with our song
    Fix the world and make it right
    When darkness finally meets the light.
    • Gets a Dark Reprise as a Survival Mantra in the finale, when Gwi-Ma has effectively won, but Rumi still shows up, alone and beaten, yet still ready to stand up. She knows she stands very little chance, but it's her duty.
  • Bait-and-Switch:
    • While HUNTR/X is singing "How It's Done" as they are beating demons trying to kill them in the plane, Mira and Zoey at one point try to eat their cup noodle, only for Rumi to pull the noodle from their hands... because both cups are still undercooked.
    • When the feline demon is about to leave, he notices a trashcan where the papers of the "TAKEDOWN" lyrics are thrown in and reaches for it... only because he is drawn to the object laying down and wants to put it back up.
    • At the Idol Awards performance of "Golden", Rumi's voice is fully healed and the Honmoon is on the brink of turning gold, only for the lights and music to cut out and switch to a performance of "Takedown" with the false Mira and Zoey that leaves Rumi humiliated, exposed, and the Honmoon in ruins.
    • After losing respect for Celine in a confrontation about her half-demon heritage being exposed, Rumi states she is glad that the Honmoon was destroyed before teleporting away, implying that she is deciding to turn her back on humanity and join the demons... only to later reveal that she intends to make a new Honmoon with "What It Sounds Like".
  • Bathhouse Blitz: HUNTR/X follow the Saja Boys into a men's bathhouse, only to realize that they've been lead into a trap and are ambushed by dozens of water demons, initiating a huge melee. Mira and Zoey acknowledge that this isn't what they meant when they said they wanted to go to the bathhouse with Rumi.
    Zoey: Don't let this turn you off bathhouses, Rumi! It's usually really FUN and RELAXING!
  • Beat Them at Their Own Game: Since the Honmoon draws energy from the fans of HUNTR/X, the demons' strategy is to create their own pop band to steal their fanbase and weaken the barrier.
  • Beauty Is Never Tarnished: Invoked. The girls do suffer cuts and bruises from their demon hunting, and they just cover them with make-up to avoid worrying their fans and manager.
  • Being Evil Sucks: Being a demon means constantly having the voice of Gwi-Ma in your ear, whispering echoes of your fears and regrets to wear down your will so you will do his bidding. For most demons, this doesn't seem to be a problem, but some like Jinu have enough good in them to want an escape from this.
  • Berserk Button: Do not threaten HUNTR/X's fans. Just don't.
    Rumi: Not our fans!
    Zoey: When you mess with our fans...
    Mira: We need to make it hurt.
  • Big Ball of Violence: During the fight on the plane, there's a shot of HUNTR/X and the demons fighting in a ball of smoke, the demons trying to flee while HUNTR/X keep dragging them back in, all while their custom rameyon cups are in the foreground.
  • Big Damn Heroes: At the height of the film's Darkest Hour, Rumi arrives to save everyone from Gwi-Ma. Though the preceding scene and the framing of her entrance doesn't make it clear that's what she's come to do at first (with it initially being implied she's about to give in to Gwi-Ma at best or join the demons at worst).
  • Big Entrance: It doesn't get any bigger than skydiving from a crumbling aircraft, landing onstage in a massive cloud of smoke, and swiftly slaying demons while effortlessly singing your opening number to a stadium of screaming fans.
  • Bilingual Bonus: Not counting the untranslated Korean lyrics in their various songs, which itself is a hallmark of modern K-pop music, the dialogue is also peppered with short phrases to flavour the various characters' personalities. Like Zoey's excited "'gajagajagaja!!!"note  or Jinu's exasperated "aishhh…"note  during his and Rumi's aborted Meet Cute.
  • Bittersweet Ending: Jinu is dead, HUNTR/X's gold Honmoon failed and an unknown number of people are still missing, but the girls saved the world and Rumi is accepted by Mira and Zoey, and it's implied demons with the capacity for good can enter the human world with the new Honmoon, as shown with Jinu's animalistic companions.
  • Black Blood: "How It's Done" has HUNTR/X openly murdering a bunch of demons on screen, with some blood coming out. However, the blood is hot pink, and not red, and has a bit of glitter to it.
  • Black Comedy: During the meet-and-greet fan event, one fan comes to get his leg cast signed. Romance, Mira, and Abby all shove the poor guy's broken leg around fighting over who gets to sign first while he tries desperately not to scream.
  • Black Eyes of Crazy: Most of the demons have black sclerae and yellow irises, a dead giveaway that they're soul-eating monsters. While the Saja Boys simply have Supernatural Gold Eyes and Hellish Pupils, the Super-Deformed drawing of Jinu's demon form in the end credits also has black sclerae and is sporting a cartoonishly evil grin to go with his Cute Little Fangs.
  • Blatant Lies:
    • When HUNTR/X track the Saja Boys to a bathhouse, Abby taunts Mira and/or Zoey by mockingly saying they're always looking at him.
      Zoey and Mira, whose eyes are exploding into lovey popcorn: NO WE'RE NOOOOOT AAAAAAAAAAAAAAA.
    • When Mira confronts Rumi about her odd behaviour around demons and the Saja Boys in particular.
      Mira: I just can't shake this feeling that you're keeping something from me!
      Rumi: ''(hiding Derpy's tail and a note for Jinu behind her back)' Mira, I'm—I'm not keeping anything from you...
    • Played for Drama twice during the Darkest Hour: Celine makes an ineffectual plan to convince Zoey and Mira, who were ready to strike Rumi down after finding out she's a demon and apparent traitor, that Rumi's patterns are fake and were part of a Secret Test of Character. This is after Rumi unwittingly demonstrated her demon powers can affect the Honmoon, which is why Zoey and Mira were prepared to kill her. In the same conversation, as Rumi blows past her Despair Event Horizon and screams at Celine why she couldn't love her completely, Celine can't even look her newly-demonic daughter in the eye when she protests she DOES love her.
  • Blunt "Yes": Rumi adopts this manner of responding when Gwi-Ma taunts her and tries to unsettle her during the climax, tersely agreeing with his declarations that she can't fix herself and that the Honmoon is gone. It's a bit unclear whether her flat accord with Gwi-Ma is because she's defiant or because she's fully given in, until she declares that the Honmoon's loss allows her to make a new one and regains her fully-human eyes.
  • Bookends:
    • The opening narration by Celine includes a flashback scene of her talking to HUNTR/X near a large tree. In the final act, Rumi meets Celine again near that same tree after her demonic patterns have been exposed.
    • Celine's narration shows the first generation of demon hunters creating the Honmoon. The final act has HUNTR/X creating a new Honmoon after the previous one was destroyed. Even the first and last concert performances of HUNTR/X in the film end by focusing on their power with the Honmoon across the landscape. We also hear the ethereal wordless singing of the first hunters during the intro, a vocal sound directly imitated by Rumi during the climax, signaling her arrival and halting the momentum of the Saja Boys' performance of "Your Idol".
    • HUNTR/X's first and last performances during the film take place in arenas with three branched runways that converge in the center of the stadium. The second time, their performance utilizes this arena design as the three girls are drawn back together and fight to the middle of the arena down each runway until they reunite.
    • After their first show, HUNTR/X are entirely ready to take a break and luxuriate in their couch, only for Rumi to begin the launch of "Golden" the moment they return home, to Zoey and Mira's brief but pronounced dismay. After their last show, HUNTR/X are again in a position to return to "couch", but unanimously agree to stay "on the clock" as public-facing idols, feeling up to the task.
    • "How It's Done", the first song of the movie, has the lyrics "Making fear afraid to breathe/Till the dark meets the light". The final song of the movie, 'What It Sounds Like" has, as the final lyrics, "When darkness meets the light/This is what it sounds like."
  • Bread, Eggs, Milk, Squick:
    • HUNTR/X have this reaction when Bobby videocalls them and some overexcited fans get hold of his phone. They scream along with some fangirls and sob along with some crying fanboys before Rumi and Zoey are weirded out when a fan shows them his huge tattoo of their group name on his left ribcage (Mira thinks it's very cool, though).
    • In "How It's Done", Rumi lists things that they would usually have as idols with one exception.
      Rumi: Heels, nails, blade, mascara.Explanation (downplayed?)
    • One of the taglines for the movie reads, "They sing. They dance. They battle demons."
  • Breaking the Fourth Wall: In the teaser trailer posted one day before the official trailer and one month before its release date, Mira and Zoey react with horror at the realization Rumi announced the official trailer for their new album the following day.
  • Break Them by Talking:
    • At the Idol Awards, Jinu breaks Rumi by weaponizing HUNTR/X's own anti-demon Diss Track against her half-demon heritage, delivered by demons disguised as Mira and Zoey. In a panic, Rumi flees directly into the real Mira and Zoey with her demon patterns on full display - and they are understandably upset that Rumi is apparently a demon traitor.
    • This is Gwi-Ma's speciality: haranguing someone with their guilt until they're a traumatized mess willing to do anything for him, either by being a demon or being a tasty morsel. When Jinu tries to take Rumi up on her offer, Gwi-Ma forces him into breaking Rumi by chewing him out as he forces him to relieve his memories of abandoning his family for a life of comfort. Afterwards, he brainwashes Bobby, Mira, Zoey, and the entirety of Seoul by confronting them with their greatest fear coming true after the despair caused by the HUNTR/X breakup. He tells Bobby he's now alone, Mira that she never deserved either her biological or adopted family, and Zoey that she's annoying and worthless, making them march to their deaths at Namsan Tower shortly afterwards.
  • Brick Joke:
    • Mira showing up to the Met Gala in a sleeping bag seems like just a one-off gag. Guess how the Saja Boys end up crashing HUNTR/X's signing?
    • HUNTR/X shout "For the fans!" just before they carb load in the plane during their World Tour. Then at the "Play Games With Us!" show, they had to play along in sliding into the ball pit because Rumi says it's "for the fans".
    • At the beginning during "How It's Done", Rumi tosses away a heart-shaped makeup compact which is used for a tracking shot. Later on, it's shown that not only do Mira and Zoey have their own matching ones, Rumi had to get a new one that doesn't match.
    • During the Saja Boys' debut performance of 'Soda Pop', Romance is shown to have the ability to create hearts out of thin air. During the hot sauce drinking challenge on "Play Games With Us!", before passing out, Romance painfully belches out a flaming heart that crumbles into ash shortly afterwards.
    • The doctor that Zoey drags Rumi to for voice tonics is shown to be such a big fan of KPop idol groups he puts stickers of himself in group photos of them. Later, when Bobby is showing HUNTR/X video clips of fans copying the Saja Boys' "Soda Pop" routine on social media, the doctor can be seen in one of the clips.
    • One of HUNTR/X's fans shown to have switched to the Saja Boys fanbase is a guy who tears off his HUNTR/X T-shirt to reveal a Saja Boys' T-shirt underneath. During the Saja Boys' Idol Awards performance with Gwi-Ma, he's shown wearing a Gwi-Ma T-shirt that he later tears off to reveal a HUNTR/X T-shirt underneath after the girls manage to create a new Honmoon and defeat Gwi-Ma.
    • Rumi's unwillingness to go to the bathhouse with Zoey and Mira (for good reason, given that Rumi is hiding her demon patterns from them) is brought up frequently. After their first performance, the Saja Boys flee into the bath house, to Zoey's great joy.
      Zoey: "We finally get to go to the bathhouse with Rumi!"
      • By the end of the film, Rumi's half-demon nature has been revealed, she's made her peace with it, and Mira and Zoey have accepted it - so they finally go together.
    • In their first clandestine meeting, Rumi shows off near-silent parkour skills when sneaking up on Jinu and attempting to behead him. In their subsequent meet up she repeats that feat, albeit with much less hostility.
      Jinu: "You made me come all the way out here so you could Jump Scare me?"
  • Broken Smile: During the Darkest Hour and Near-Villain Victory after Mira and Zoey find out Rumi is half-demon and reject her, Zoey gives a small, sad smile that she's finally found a place that accepts her after Gwi-Ma preys on her insecurity and need to please... even if that place is "getting her soul eaten by a demon king". It's played for Black Comedy when the same traumatized smile returns during "Your Idol", because Mystery just started singing.
  • Calling the Old Woman Out: Near the climax, after Mira and Zoey have found out that Rumi is half-demon, Rumi runs to Celine, gives the older woman her sword and tells her to "do what she should've done before" but Celine panickingly tells her that it can be fixed and they can just say what they saw was an illusion by the demons. Rumi quickly calls her out for always hiding her patterns and never accepting her demon side, pointing out that Celine is struggling to even look at her in this very moment.
  • Casting Gag:
    • In the Japanese dub, this is not the first time Minako Kotobuki, as Rumi, voiced someone who's a member of a music band.
    • The Latin American Spanish dub is a meta example of this. The dub was done in Argentina, a country with a very notable Korean community, and as a result, it's one of the few Latin American countries, aside of the U.S. and Mexico, that had the best resources for translating from Korean to Spanish, and being one of the main countries, with Mexico and Venezuela, to dub and translate Korean media, even if the film's main language is English, with some Korean peppered along the way.
  • Casual Danger Dialogue: Despite their plane being cut in half from a recent demon attack, the three heroines are unconcerned as they note that their ride is over, finish their cup of hot noodles, and jump off to skydive down to their stage.
  • Celebrity Endorsement: In-Universe;
    • HUNTR/X have instant ramyeon that have what is presumably their trademark flavors: Rumi's is Superstar Flavor, Mira's is Spice Queen, and Zoey's is Hamburger.
    • The Saja Boys have a soda brand called "Saja Boys" which ties-in with their song Soda Pop.
  • Central Theme: Shame and how to overcome it:
    • HUNTR/X's struggles with hiding their imperfections illustrates how trying to bury or forget what you're ashamed of will only give it more power over you, and the real way to move past it is to seek support from the people who know you're more than your worst traits and to fully accept that no one, including you, is perfect. It's in full display in the film's opening act: first we get a montage of excited fans gushing about HUNTR/X on camera, highlighting the glamour and influence these singers have towards the public and how spotless they must present themselves as. It's then immediately contrasted by the trio's proper introduction aboard their private plane, where they pig out on snacks before their concert in a cartoonish and obscene manner, showing that behind closed doors they aren't the perfect figures the public frames them as, but it's also what gives them appeal and relatability.
    • The theme is also explored with the struggles of Rumi and Jinu:
      • Rumi's half-demonic heritage is directly at odds with her role as a demon hunter, and she's kept it hidden from her friends and fans for years believing that they make her a disgrace. An assumption enforced by Celine's prejudiced conditioning. Continuing to hide the markings causes Rumi's capabilities as both hunter and singer to go awry, and it's only after embracing her demons that she can be her best and most honest self.
      • Jinu has dealt with the guilt of leaving his mother and sister behind to escape poverty after making a Deal with the Devil with Gwi-Ma, condemning him to becoming a demon for 400 years. He feels that his actions makes him irredeemable and that he can only do evil, but through making friends with Rumi and her empathizing with him is what ultimately convinces Jinu that he can still do what's right.
      • The lyrics to their duet in "Free" also puts emphasis on this:
        I tried to hide but something broke
        I couldn't sing, but you give me hope
        We can't fix it if we never face it
        Let the past be the past 'til it's weightless
  • Cerebus Syndrome: Even if the premise of demons threatening humanity is introduced from the get-go, the first third is pretty heavy on humor, as it features HUNTR/X getting into goofy shenanigans and making lots of Animesque silly faces. They all quietly disappear once the plot proper kicks in and the tone takes a more dramatic shift. Even the demons, who are not remotely a challenge in the first third, become more of a threat later on.
  • Chekhov's Gun: The song "TAKEDOWN" doesn't seem like one at first, instead being used as a plot device for HUNTR/X's character development where the girls seemingly slip away from what made them such successful idols and Hunters in trying to bring hatred and loathing down on a group. Then they come to a Heel Realization that what they've been doing simply doesn't work and they return to their roots of "using music to ignite the soul and bring people together." so they put down the gun and discard the song. Only for the demons to pick it back up and fire it off at Rumi.
  • Cheshire Cat Grin: Played for Laughs when Mira and Zoey’s relaxation is immediately interrupted by Rumi rising in a very cartoonish way from behind the couch with a wide grin, asking if they enjoyed their break.
  • City Shout-Outs: The demo version of "Golden" that EJAE submitted has slightly different lyrics. There, the last line in Mira's part is "From Seoul to L.A.", instead of the final version's "끝없이 on stage".
  • Civilians Are Irrelevant: A hard aversion; while The Masquerade is in full effect, the source of power that the Hunters draw on come directly from the very people they protect. And it's thanks to the massive audience present in the final battle that HUNTR/X gets powered up enough to defeat Gwi-Ma.
  • Clark Kenting: The pop stars with millions of adoring fans barely have to disguise themselves to go out in public. Rumi just wears a hoodie to hide her purple hair, Zoey wears a bucket hat, and Mira wears glasses. Sometimes they don't even bother, and yet don't get immediately mobbed by countless excited fans.
  • Competence Porn: Unusually for female protagonists, HUNTR/X start the story with a job that they are very good at, well respected for, and enjoy a lot. Their primary weakness is their fear of losing what they have.
    Mira: (after discovering Rumi's Dark Secret) I knew it. I knew it was too good to be true.
  • Combined Energy Attack: The Honmoon isn't an attack, strictly speaking, but rather a mystical barrier between the human and demon worlds forged by bonding with the souls of those hearing the songs of Hunters. During "What It Sounds Like", HUNTR/X is outright empowered by the renewed spirits of their audience, allowing them to turn the tables on the Saja Boys, forge a new Honmoon, and banish or destroy Gwi-Ma.
  • Concert Climax: Fitting for a musical about pop superstars, the final battle to seal Gwi-Ma is set at a giant concert where the Saja Boys are performing.
  • Conveyor Belt Video: After the Saja Boys' underhanded social media vid thanking their fans, the camera pans to the right in two bouts. One from their latest fan's soul being eaten by a Joseung Saja demon to a news reporter informing about a wave of disappearances. Next to the TV, we slowly slide through a corkboard filled with missing person posters up to a rain of souls feeding Gwi-Ma.
  • Crash-Into Hello: Played for laughs during the Saja Boys' introductory scene. Right after calling Zoey and Mira out for fawning over four hot guys, Rumi finds herself gawking at their leader Jinu. Cue romantic music and slow motion as Jinu approaches her and knocks her with his shoulder, causing her to fall over (making funny faces all the while). He then tells her to watch it, breaking the spell.
  • Crazy Enough to Work: Sending a demon boy band to steal HUNTR/X's fans is such an absurd plan that Gwi-Ma bursts out laughing when Jinu proposes the idea. As it turns out, said plan was probably the most effective attack on the human world in 400 years.
  • Creative Closing Credits: In the credits, the characters are drawn in anime and chibi styles, and then live-action footage is shown of TWICE recording their version of "Takedown".
  • Creator Backlash: In-Universe; "Takedown" ends up causing more problems than it solves as Rumi really can't get past the hateful lyrics, feeling it isn't in line with HUNTR/X's usual uplifting message, especially after getting to know Jinu. This disconnect with the song also spills over into the group as they end up arguing about it. In the end, the girls decide to abandon the song for the good of the group. The song then ends up being used against the girls and causing their almost complete split, so it's no stretch to say none of the girls have any good feelings for the song by the end of the movie. This is shown even on a meta level as when the song is put up on social media like YouTube and Spotify it is credited to the real life K-pop singers TWICE, unlike other HUNTR/X songs like "Golden" and "How It's Done" are.
  • Creator's Culture Carryover: Despite being set in Korea, this is an American-made film, and some details hew much closer to American than Korean culture industry norms.
    • invokedAfter the Saja Boys crash HUNTR/X's autograph signing session, fans of both groups start shipping the members together, and even HUNTR/X's own manager Bobby shows some enthusiasm about it. In North America, this wouldn't be seen as a big deal. However, the Korean Pop Music industry is very strict about their Idol Singers' Contractual Purity—not only are they discouraged from dating, but their images are carefully crafted in order to sell the fantasy that they could date you, their fan, since they're always available, so anything that could be vaguely misconstrued as romance is right out. The vast majority of shipping theories are set within a group or carry whiffs of fandoms duking it out, and some fans get very angry about theories of inter-group relationships.
    • Mira's openness and defiance about being estranged from her family probably wouldn't fly in the real Korean music industry. While there are certainly idols who are known to have family issues and receive the public's sympathy (Tiffany Young and her father come to mind), it's generally kept quiet rather than used as a selling point, particularly if the cause of the split was Mira's own behavior; some would prefer idols with a greater sense of filial piety — as opposed to America, where being estranged from your parents is borderline-Cool People Rebel Against Authority material (e.g. the support for Britney Spears during her fight to be removed from her father's conservatorship that pushed her to several breakdowns, which also came in hot on the heels of #MeToo and a bigger discussion on mental health).
    • American pop diss tracks are a dime-a-dozen (see: Justin Timberlake's "Cry Me a River" against his ex Britney or Taylor Swift vs everyone at this point), but an open diss track like "Takedown" would be a PR death sentence for a K-pop group — instead, as with when Western companies try to be subtle about sabotaging rivals, Korean companies rely on Fandom Rivalry, rumourmongering, and PR smears, even if the musicians involved don't have any beef, such as the time NewJeans' former agency were caught trying to stoke a Flame War between them and another idol group. invoked
  • Creator In-Joke: Zoey is said to have grown up in Burbank, California, which is where most of the film's animators live, and a major hub for American animation in general.note 
  • Cue the Sun: In the finale, the Saja Boys' special performance explicitly starts at midnight, and when HUNTR/X defeats Gwi-Ma at approximately 12:08 am, it's suddenly a bright, beautiful, sunny day.
  • Curb-Stomp Battle: The film's opening act has HUNTR/X being ambushed on their private plane by a group of demons. Not only are the girls completely unafraid and unimpressed by the demons, but they then proceed to utterly humiliate the latter while nonchalantly finishing their meal. Then skydiving without parachutes onto their concert stage, while still beating the crap out of the demons, and then eventually slaying them in front of their audience.

    Tropes D to G 
  • Darker and Edgier: The title and premise of the movie sounds quite silly with having multiple comedic moments, but it's certainly one of the most serious and emotional films Sony Pictures Animation has ever made with their Spider-Man: Spider-Verse films since it also deals with some intense, mature themes that are pretty shocking despite its PG rating. Of particular note is when Rumi asks Celine to kill her when her shame over her demon patterns and Mira and Zoey's recent rejection becomes too much for her.
  • Darkest Hour: At the Idol Awards, after being forced to relive his abandonment of his sister and mother by Gwi-Ma, a broken Jinu runs a False Flag Operation that reveals Rumi's demon patterns to the public and her best friends. A disgusted and betrayed Zoey and Mira rebuff Rumi's attempts to explain she was just using Jinu to lock away her demon side, and Rumi is too freaked out to do anything more than scream, which affects the Honmoon and forces a shattered Mira and Zoey to threaten her into fleeing. Her hopes that Jinu wasn't behind the breakup are dashed when he reveals that, yes, he did it, and as a demon, he doesn't deserve anything more than pain. Gwi-Ma enthralls Bobby, Mira, Zoey, and ALL of Seoul by pointing out their worst fears have come true and to come to Namsan Tower under the guise of a Saja Boys concert, set to reign on Earth and consume humanity. Meanwhile, a despairing Rumi confronts Celine and ''begs her adoptive mom to kill her — and when Celine refuses, Rumi falls into further despair when Celine can't bring herself to accept Rumi now that she's undeniably a demon. Rumi leaves after ominously stating she'll be glad to see the Honmoon destroyed, apparently set on joining Gwi-Ma...
  • Dark Reprise:
    • The song "Takedown" was written by HUNTR/X to be The Diss Track and a "The Villain Sucks" Song aimed at the Saja Boys, but at the Idol Awards, demons disguised as Mira and Zoey sing it in Rumi's face to taunt her about her mixed demon blood.
    • A somber, instrumental version of "Golden" plays when Rumi's demon side is exposed to an angry Zoey and Mira, who turn their weapons on an apparently traitorous Rumi.
  • The Dark Side Will Make You Forget: Downplayed; Gwi-ma tends to force his servants into submission by making them remember the shame of their turn to the dark side, and only make them forget after they have fully submitted to him. Jinu spends most of the movie attempting to invoke this trope — if Jinu breaks the Honmoon, Gwi-ma will erase Jinu's memories of him betraying his mom and sister.
  • Dartboard of Hate:
    • HUNTR/X set up a wall at home with the Saja Boys' pictures. Jinu's is actually on a dartboard which Mira offhandedly threw a few darts at.
    • At HUNTR/X's green room at the Idol Awards, Mira has a punching bag with a picture of Abby Saja's abs.
  • Dating Catwoman: Rumi and Jinu start developing romantic feelings for each other very quickly, which they both try to hide under constant bickering.
  • Deal with the Devil: Jinu made a bargain with Gwi-Ma four hundred years ago to get out of poverty. He got his wish, but became a demon in the process.
  • Deathly Dies Irae: "Your Idol" samples a musical motif from dies irae as its opening, complete with a slow Ominous Latin Chanting hymn with backing vocals that repeatedly say "Pray for me now". Fittingly, the Saja Boys sing this at the concert where they plan to corrupt the fans. The hymn, however, is not directly copied, and the song instead translates to the following, with the part after "favilla" not being found in the original hymn (Note the difference after "that day."):
    Dies irae illa, vos solve in favillaTranslation
    Maledictus erus, in flamas eternumTranslation
  • Declarative Finger: During "How It's Done", Rumi did this to the large demon to stop his action as she sings and fill a pitcher with hot water for HUNTR/X's instant cup ramyeon.
  • De-Power Zone: The opening montage shows the Honmoon enveloping only the Republic of Korea, in an apparent reference to the DPRK's longstanding ban on RoK media.
  • Despair Event Horizon: After the Idol Awards, Rumi is distraught to the point that she outright asks Celine to kill her.
  • Desperate Abuser Apology: For most of Rumi's life, Celine was the only one who knew that she was half demon. She raised Rumi to believe that her demon side was something to be ashamed of, and that she must always hide that part of herself, especially from Zoey and Mira. This caused Rumi to have serious self-esteem issues as an adult. When a plot by the Saja Boys causes Rumi's demon heritage to be revealed to her bandmates (which causes the Honmoon to further deteriorate), Rumi goes to Celine and confronts her for years of hiding who she is. Celine begs for forgiveness, but ruins her own apology by desperately saying they can "fix this" by covering up Rumi's marks and telling her bandmates it was just a trick. Rumi is disgusted, and makes it clear she doesn't want to hide anymore.
  • Detrimental Determination: With the possibility of making the Honmoon permanent, Rumi pushes the other two into releasing a single immediately after finishing a world tour without a break. The extra work harms her voice, which leads to them having to reschedule and gives the Saja Boys an opening.
  • Did Not Get The Guy: In the climax, Jinu performs a Heroic Sacrifice to save Rumi from Gwi-Ma.
  • Did You Just Punch Out Cthulhu?: In the climax, HUNTR/X draws on the Power of Friendship and their fans to use a Combined Energy Attack to defeat Gwi-Ma, but it’s unclear if he is killed or merely banished back to the demon world.
  • Did You Think I Can't Feel?: Jinu is genuinely offended when Rumi states that demons do not have feelings during their first meeting at the rooftops. He snaps that existing as a demon consists of nothing BUT feeling, by which he means he is tormented by the regrets of his past and the constant presence of Gwi-Ma amplifying his sense of shame and unworthiness.
  • Disappointed by the Motive: When Rumi finds out that Jinu's motive for stealing souls for Gwi-Ma is to have his own memories erased, she calls it "pathetic."
  • Disney Acid Sequence: "Free"—one of two non-diegetic, "break-into-song" musical sequences in the film—is presented this way, with the city background giving way to abstract lights and the lead characters flying.
  • The Diss Track: HUNTR/X first try crafting the song "Takedown" to be an epic, well, takedown of the Saja Boys, calling them out for being demons who are manipulating their audience and secretly being evil. However, Rumi quickly turns on the lyrics of the song, since they come way too uncomfortably close to sounding like they apply to her and how she's been hiding her half-demon heritage from her bandmates, giving her a massive crisis over her internalized hatred of herself. Crucially, Jinu exploits this at the Idol Awards by making demon versions of Mira and Zoey sing the song at Rumi, which works exactly as intended and causes her to lose it onstage out of grief.
  • Disowned Sibling: Mira's siblings are implied to want nothing to do with Mira, just like her parents. This winds up Foreshadowing her own estrangement with Rumi after Rumi is outed as a demon and an apparent traitor, and then her estrangement with Zoey after she's broken by Gwi-Ma reminding her she lost two families and never deserved any of them, callously brushing her off by saying she doesn't get to have a family.
  • Does This Remind You of Anything?:
    • One of Celine's biggest lessons for HUNTR/X is that their flaws and insecurities must never be seen by the public. No matter what, they must maintain their perfect image, no matter how damaging it is for them as idols and as people. Take away the fact that otherwise demons will invade and you have a very major issue permeating many entertainment industries, idols especially.
    • Rumi's voice failing despite her best efforts and her breakdown over despite everything it's still not good enough, demanding why when she's so close. Why can't she sing well...compare questioning why despite everything one can't stop smoking, one can't lose weight, one can't maintain a relationship.
    • Rumi refusing to bathe with Zoey and Mira in order to hide her demonic marks brings to mind a person trying to hide self-harm scars or to hide their own body image issues.
    • Rumi's desire to hide her demon half is highly reminiscent of someone trying to hide being LGBTQ+, as are her interactions with Celine, especially at the end, where she realizes that Celine has never truly accepted her entire self, and sees that part of her as something to be permanently blocked off. Also those with congenital abnormalities, mental and/or physical disabilities, affair babies, or simply those of "mixed race."
    • At the Idol Awards, the demons impersonating Zoey and Mira tearing Rumi's jacket off and exposing her patterns on stage is framed in a way reminiscent of sexual assault, complete with the demons invading her personal space, sporting Slasher Smiles that resemble lustful stares, a mortified Rumi begging said demons to stop, covering herself like she's naked, and ending in a meltdown on stage.
    • While Jinu is meant to be seen in a sympathetic light, his interactions with Rumi are very reminiscent of the dangers in dating strangers such as in online dating. He gets Rumi to drop her guard by using cute pets and a not-completely-true story of his life that is clearly meant to connect with her. He makes Rumi feel isolated and that he is the only one she can share her secrets with. He has secret meetings with Rumi that her loved ones are not aware of. Then when Rumi exposes all her insecurities to him, Jinu uses them to publicly humiliate Rumi at the Idol Awards, complete with a Shameful Strip. In the aftermath, Rumi's friends turn on her when they realize she is keeping secrets from them and Rumi even contemplates allowing Celine to kill her.
    • The Concert Climax resembles a mass cult suicide: a group of people, all on the brink of despair, are lured in by a charismatic figure who claims to have the answers... and subsequently leads them all in a ritual that ends in suicide, that being the crowd willingly walking into Gwi-Ma's fire. Granted, in this case, it's heavily implied actual magic is involved, since the crowd doesn't seem entirely aware of what they're doing as they climb onto the stage.
    • Gwi-ma is a monstrous "king" lording over his subjects who cares for nothing but raking in souls to eat at all costs, whom he forces impossible standards and tasks on, disposes of mercilessly when they inevitably fail because he can't think of anything else besides the same thing he's been doing over and over again. And on the off chance one of his subjects breaks the mold and succeeds, Gwi-ma is all too happy to abuse them relentlessly even when their subject's performing well, using shame and fear to control them, forcing them to carry out attacks on other idols against their will, and disposing of them the moment they slip up. He's an allegory for abusive managers and record labels in the Korean music industry who drive their performers to the breaking point, force them to feud with other pop bands, and then throw them in the trash once their fame is up.
  • Double Entendre: The two bands' song lyrics double as radio-friendly pop hits and songs about their role in the hunters/demons conflict.
    • "How It's Done" is a boastful song any confident girl group might be able to release to assert dominance on the charts, which is how the in-universe audience sees it, but we know it's about HUNTR/X's prowess for demon-slaying in reality.
    • "Golden" is an autobiographical track discussing how HUNTR/X found their places and how together they're "glowing" and "gonna be golden". It's also a song intended to give them the power as music stars and magical warriors to create the golden Honmoon enchantment every generation of hunters has tried to create.
    • "TAKEDOWN" is written as a diss track against the Saja Boys, with lyrics that scan as insults toward targets framed as mundane posers and manipulators ("...when your patterns start to show...") while also being directly tied to the lore of their demonic nature (demons are literally marked with skin patterns that reveal their true nature). The song also has subtext of Rumi as the target, since she has hidden her demon heritage and lied, which makes her hate herself and drives the band apart after the very song is used against Rumi by the demons while exposing her.
    • On the Saja Boys' side, "Soda Pop" is a fluffy bubble-gum romance number where the singers call the object of their affection a "soda pop" they can't get their fill of. It's a veiled metaphor the in-universe audience never grasps—they're actually singing about drinking up the audience's souls as if they were sodas. The bit is shown to have continued once they got an actual branded soda pop product, as the cans have an "ingredients: 100% you!" blurb on them that sounds like a cute tribute to the fans but is actually a veiled admission that the Saja Boys' desired "soda pop" is the souls of the fans.
    • Also by the Saja Boys, "Your Idol". The song is the point where their pretense has basically ended, as the band goes mask-off before an entranced mob and sings explicitly about being the audience's obsession and salvation as a lure to the maw of Gwi-Ma, so the entendre comes more with meta-commentary. The lyrics question K-pop idol culture and the manipulative, addictive, and selfish potential of cultivating fans and influence, playing up the darker side of crafting oneself into an idol by directly comparing manufactured music idols to hungry demons who are purely using their fans and building a hollow cult.
  • Do Well, But Not Perfect: The wall between human and demon realms can be strengthened to the point it turns gold, which indicates a perfect, permanent wall that no demon can penetrate. However, this is not a good idea because some demons are effectively normal humans enslaved by Gwi-Ma's magic. They may retain some of their personalities, be no less willing than humans to do good, and have been coerced into joining Gwi-ma's side in the first place note . Creating a golden Honmoon hypocritically condemns people like that to rot in the demon realm forever over one bad decision. Fortunately, a better option exists.
  • Dramatic Irony: As the Saja Boys continue to grow in popularity and attract more and more of HUNTR/X's fanbase, Bobby tries to calm himself down by saying that it's just social media hype and not the end of the world. Cue cut to the HUNTR/X' point of view, who see the Honmoon getting weaker and weaker, signaling that the threat of a complete demon invasion is growing.
  • Dumbass Has a Point: The Eastern traditional medicine doctor who cut-and-pastes himself into celebrity photos and ends up selling the girls grape juice disguised as miracle tonic makes some very accurate observations about Rumi putting up walls and Zoey being too eager to please.
  • Eagleland: Stereotypical American-ness is indicated to be part of Zoey's image thanks to her background growing up in the USA, even if she's not actually made tangibly separate by the film's portrayal of her compared to the cast of Korean characters who lived there their whole lives and doesn't visibly "behave American" in any contrast to the others. Zoey's quickly described by fans as the one who lived in America, her branded HUNTR/X ramyeon cup depicts her in stereotyped U.S. patriotic fashion, and the ramyeon's flavor and name are a blunt "Hamburger" to hit the stereotype home, as opposed to Mira and Rumi's more elegant ramyeon names (Spice Queen and Superstar Flavor) and Korean flavors. Zoey also sings about feeling caught between two worlds and being insecure about it in "Golden", suggesting her placement as "the American one" in the band can make her uncomfortable sometimes.
  • Eating the Eye Candy:
  • Establishing Character Moment:
    • The beginning of the film briefly goes over HUNTR/X's demon hunting training and their individual roles in the group (Rumi is the lead singer, Mira is the visual/lead dancer, and Zoey is the rapper/lyricist), but the first actual scene with the girls has them binging snack food so they can carb load before their concert before fighting off some demons that threatened their fans, because nobody messes with their fans! HUNTR/X may be talented performers and totally badass fighters, but they are also total goofballs.
    • Jinu's introductory moment shows him mocking the demon king Gwi-Ma with a song. Not only does this immediately demonstrate his talent at singing, it also hints at how he doesn't really want to work for Gwi-Ma.
      Gwi-Ma: I let you keep that voice, Jinu. And you dare to mock me with it?
    • When the demon tiger first appears, he's unquestionably creepy: the size of a tiger, the wretched fangs of a carnivore, and those glowing eyes. Then he knocks over the flower pot and instantly gets distracted trying to fix his mistake. In just one interaction, we learn everything we ever need to about "Derpy": He absolutely could hurt Rumi; he absolutely never would.
  • Establishing Series Moment: "How It's Done" is the thesis statement of the film, blending music, gorgeous animation, and over-the-top demon-slaying action that peaks with HUNTR/X skydiving from their ruined plane, and doing their hair and makeup in freefall while still singing and fighting. While the emotional turmoil that defines the film's central conflict is nowhere to be seen, the "How It's Done" sequence gives you a pretty good idea of what to expect from the art, choreography, and music direction.
  • Everyone Hates Hades: The demon boy band is implied both by their name "Saja Boys" and their appearance (a black hanbok and a heungnip; a wide-brimmed black gat, a hat worn by those who passed the gwageo, the national civil service examination before the late 19th century) to be Jeoseung Saja. Joseung Saja are usually portrayed as neutral death spirits that simply guide souls to the afterlife, rather than stealing or eating them.
  • Everyone Is Bi: Or at least, HUNTR/X's fanbase is implied to be this; when Jinu denys being Rumi's boyfriend as "she's not even my type", Rumi, hilariously shocked, replies "Excuse me?! I'm everyone's type!"
  • Everything's Better with Rainbows:
    • When Rumi finally accepts her half-demon nature, her markings change from dark red to neon rainbow.
    • Similarly, the new Honmoon has a rainbow tint.
  • Exact Words: A big reason why Jinu shouldn’t have made a deal with Gwi-Ma in the first place. Back when he was just a poor human and street musician struggling to save his family from starvation, he sold his soul to the demon king in order to get him out of poverty. Gwi-Ma granted his wish, but his family stayed poor until their death, because Jinu never specified that the demon king should have gotten them out of poverty as well.
  • Exactly What It Says on the Tin: This is a movie about demon hunters who sing K-pop. The title even works with an alternate interpretation of the title as "hunters of K-pop demons", given that the primary antagonists in the movie are a demon boy band. Or even "K-pop Demon who Hunts," as Rumi is a K-pop idol and half-demon who hunts other demons.
  • Excuse Me While I Multitask: To show how easy their job is, HUNTR/X make cup ramyeon while beating up demons in their private jet. Then during the Free-Fall Fight, they touch up a bit with makeup just before entering the concert venue's airspace.
  • Extra-Strength Masquerade: The world at large still views demons and Gwi-Ma as mythological figures despite the fact that HUNTR/X has fought demons live on stage after dropping out of a plane without parachutes, simply attributing it to excellent special effects, with the implication that this is far from abnormal for them. Likewise, no one bats an eye at the Saja Boys conjuring a soda pop can stage out of nowhere or being able to fly and teleport during their final concert.note 
  • Eye Pop: Han's eyes get huge when staring down the girls to figure out their ailments.
  • Failed Attempt at Drama: Zoey tries to tear apart her notebook with the "Takedown" lyrics in response to Rumi rejecting the song. Turns out it's not so easy to tear a bound book. She struggles futilely for a few seconds before settling for tossing the whole thing.
  • Failed Dramatic Exit: After siccing a horde of water demons on HUNTR/X in the bathhouse, Jinu attempts to do a "back away while taunting" exit, and nearly slips in a puddle with a panicked "oh, jeez!" His goofy giggle as he runs off doesn't make him look any cooler.
  • False Flag Operation: At the Idol Awards, Jinu, after being put in his place by Gwi-Ma, starts the plan to sabotage HUNTR/X by falsely delaying the Saja Boys from performing so that the trio will have their spot to sing "Golden" on stage and have a demon pretend to be Bobby being kidnapped by other demons, luring away Mira and Zoey. And then the two more demons appear on stage disguised as the latter two hunters, singing "TAKEDOWN" to Rumi's face. The plan succeeds with Rumi being exposed and humiliated before the audience.
  • Family Portrait of Characterization: During the fans' exposition before the "How It's Done" concert, Mira's "black sheep of the family" backstory is supplemented with a second family photo where she's not sitting properly and isn't dressed formally unlike her three other family members. This alone easily explains her rebellious attitude.
  • Fan Disservice:
    • HUNTR/X's inadvertent appearance on the Variety Show. Never have leather Spy Catsuits been less sexy than when that leather is causing them to slowly and loudly squeak down a slide before landing face-first in a ball pit.
      Zoey: The leather has betrayed us!
    • At the bathhouse, an old man shows up wearing only a towel wrapped around his waist, sending HUNTR/X out with swiftness. However, he ends up having his soul consumed by a demon from behind afterwards.
    • Rumi at the Idol Awards. A gorgeous woman in a crop top and tiny shorts is a lot less sexy when it's because demons disguised as Mira and Zoey ripped off her jacket and exposed her markings to the world, causing her to hit her Despair Event Horizon.
  • Finger Wag: HUNTR/X deploy a particularly sassy one of these during "How It's Done."
    Body on body, I'm naughty, not even sorry
    And when you pull up, I'll pull up
    A little late to the party (la-la-la-la!)
  • Finger-Tenting: Rumi tents her fingertips together as she says, "Yes... vacation," showing that anything she told her bandmates about being able to rest after their "Final World Tour" concert was a grotesque lie.
  • First-Episode Twist: The existence of Rumi's demonic patterns is a huge twist that is revealed to the audience early on and drives most of the movie's plot afterwards.
  • Fist of Rage: After the joint signing event, Mira starts trembling with rage and a clenched fist when she learns fans have begun shipping her with Romance and Abby.
  • Five-Second Foreshadowing:
    • Before the signing starts, Bobby mentions fans who've been sleeping outside of the meet and greet since the previous night. Cue five suspiciously conspicuous "fans" waddling in wearing sleeping bags, who turn out to be the Saja Boys crashing the signing.
    • Mira and Zoey are lured away by demons masquerading as Bobby getting kidnapped, demonstrating that demons can disguise themselves as people HUNTR/X know, moments before demons disguised as Mira and Zoey accost Rumi on stage. During the event itself, Rumi (and the audience) know something is very wrong when Mira and Zoey sport Slasher Smiles that look nothing like the goofy smiles they've put on through the entire movie.
  • Five Stages of Grief: Rumi undergoes this with her secret of being half-demon being exposed to Mira and Zoey: Denial (refuses to believe that Mira and Zoey won't easily forgive her for lying to them for all these years and secretly meeting with Jinu to fix everything), Anger (decides to furiously lash out at Jinu for exposing her secret, destroying her friendship with her two closest friends, and betraying her trust), Bargaining (goes to Celine in hopes she would kill her for "being a mistake"), Depression (becomes saddened that Celine can't love all of her and she still tries to cover up her half-demon heritage) and Acceptance (mournfully accepts that both she is half-demon and that she can't fix it but goes to save the world anyway).
  • Food Porn: The carb loading sequence is rife with this, sometimes literally, as is the case with Rumi scarfing down her kimbap, and of course, the ramyeon the girls quickly slurp up before free falling from the plane.
  • Foreshadowing:
    • A drink can's pop-tab sound effect is heard when the Saja Boys put on their first layer of boy-band glamour during their pitch to Gwi-Ma, foreshadowing the hit song they're going to make a splash with, "Soda Pop", which also uses the sound effect in the mix.
    • Rumi being half-demon is slowly hinted at before being fully revealed. All within the first twenty minutes of the film.
      • Rumi's hair is indicated to be natural by her having the color even as a child, and it's a shade of purple, a key color associated with the demons and their patterns and magic. Rumi is half-demon and the patterns are revealed on her skin in time, as well as her showing demon powers later. Her hair tone also contrasts the golden uniforms HUNTR/X wear in anticipation of creating the Golden Honmoon, showing that Rumi is going to find herself at odds with the mission once she has doubts about eradicating demons. Rumi's hair being a gentler lavender purple also foreshadows that she will remain on the side of good, and her patterns ultimately shift to rainbow pastels that make her hair color more harmonious by the end as she accepts herself.
      • Rumi reveals in the introductory fight, when facing demons on HUNTR/X's private plane, that demons have purple marks on their bodies that give away their true nature. Which makes it more of a surprise when she herself is revealed to have these marks too.
      • When Rumi uses the Rider Kick-like attack on the large red demon during HUNTR/X's impromptu skydiving, it briefly glows purple, then blue from the Honmoon that she and her fellow hunters often use.
      • She conspicuously keeps her body covered in all of her outfits save for a small piece of her midriff. Because her body's covered in demonic markings.
      • The music video for "Golden" opens with Rumi in a dark room, with a single ray of light falling over her left eye. When Rumi gets overtaken by her demonic transformation, her left eye turns an inhuman yellow.
      • Moments before HUNTR/X goes on stage to record for their new single, Mira and Zoey prepare in a dressing room separate from Rumi, as the scene slowly shifts to the latter alone and reveals her shamefully unveiling the markings on her arms before covering them again.
      • Rumi’s first clue that the flight attendant is a demon is her strange smile. Rumi herself has the exact same smile while springing on her band mates that she's already announced the release of Golden.
    • It's repeatedly hinted early on that Jinu doesn't really like working for the demon king Gwi-Ma. Jinu's Establishing Character Moment shows him mocking Gwi-Ma with a song. Then when Gwi-Ma compilments Jinu because the latter's idea of a demon boy band is actually working, Jinu awkwardly smiles and looks down, seemingly not wanting the compliment.
    • Gwi-Ma points out that Jinu doesn't do anything that doesn't benefit him, which cuts to a memory of a mother and her crying daughter. When Jinu explains his origins to Rumi, we know he's lying about helping his family since he actually abandoned them when he made a contract with the Demon King.
    • Although it's more lighthearted, Rumi sports an eerie Slasher Smile when she pushes her groupmates to stop relaxing and immediately get back to work. It looks identical to the ones that the demons that were on their plane and the Saja Boys had when they talk to the girls in their disguises and humiliate HUNTR/X on live TV respectively. It's NOT lighthearted at all when the demons impersonating Zoey and Mira sport nasty, inhuman smiles as "Takedown" starts playing.
    • HUNTR/X's comical appointment with the traditional Eastern medicine doctor holds more weight than thought. In his words, 'in order to heal a part, we must understand the whole', even referencing the group as the whole. His observations of Rumi's self-esteem issues and Zoey's people-pleasing tendencies are consistent throughout the film, while Mira effortlessly scaring him from reading her hints her growing assertiveness and confrontations with Rumi. Han's analysis proves true as the group's insecurities and bond directly affect the Honmoon's dismantling and revival.
    • In the joint fan meeting event, the sitting arrangement and In-Universe fan shipping between HUNTR/X and the Saja Boys partially hint at how the final battle would play out; Mira fights Romance and Abby, while Zoey fights Mystery and Baby. A young girl also compliments Jinu for having a "beautiful soul", which surprises him enough to ponder about it. Jinu eventually avoids fighting Rumi in the end, then literally gives his soul to her instead so that she can fight back against Gwi-Ma.
    • The means of Gwi-Ma's defeat is seeded throughout Rumi and Jinu's romance. Rumi's first meeting with Jinu comes after her visit to the clinic to help her with her voice, which she fears is going away due to her demon heritage taking her over. As she bonds with Jinu over their shared demonic sides, Rumi's voice heals to the point where she is able to sing the climax to "Golden" with ease, which was presented as being the way to forever seal the Honmoon and banish demons for eternity. The fact that Rumi didn't need to banish her demon side but learn to live with it is the key to her and the rest of HUNTR/X coming together to perform "What it Sounds Like," which is about overcoming and living with their insecurities and finding strength in their bond, which in turn rebuilds the shattered Honmoon stronger than before.
    • The auntie telling Rumi to find another boy because Jinu is hopeless. Jinu ends up dying in the end in a Heroic Sacrifice.
    • Despite the girls initially being hyped to compose "TAKEDOWN" as The Diss Track for the Saja Boys, there are several hints that it was doomed to fail aside from Rumi's growing discomfort:
      • Every time HUNTR/X sang while fighting demons, the songs used were motivational numbers focusing on connecting with their fans or uplifting themselves. The one time this doesn't happen and they fail is when they struggle with singing "TAKEDOWN", a song all about hating someone who is a demon in disguise, which lacked the key ingredient that made HUNTR/X's songs so successful: an uplifting message about confidence and self-acceptance, and became too focused on the sources of their hate that it caused everyone in the train car to have their souls stolen before the three even realized it.
      • We learn from Rumi and Jinu's first rendezvous that Gwi-Ma controls the demons through self-hate and shame. Then during their private conversation at the fan singing, Jinu points out that he would have freed himself from Gwi-Ma centuries ago if hate was all it took. On the other side of things, Mira and Zoey's investment in the song's creation notably heightened their disgust towards all of demon kind and annoyance with Rumi's reluctance. This allowed the song to be hijacked by Gwi-Ma to expose Rumi's demon heritage at the idol awards and cause Zoey and Mira to turn on her in a Moment of Weakness. The three of them gave Gwi-Ma everything he needed to tear them apart.
      • The lyrics promise "I'ma cut you open," "you'll be begging and crying, all of you dyin'". Rumi's outfit is cut open to reveal her demon heritage and is reduced to tearful begging thrice: when her fake bandmates are exposing her demonic patterns, when she tries to get a betrayed Mira and Zoey to not abandon her, and later when she begs Celine to either kill her or accept her flaws. The plan to kill and eat the souls of everyone in Seoul also almost goes off without a hitch.
    • In the flashback to the first Hunters and all the subsequent music groups that followed leading up to the Sunlight Sisters, there is a recurring color motif in their outfits, either worn as an accessory or seen in the detail of their clothing: An iridescent, neon rainbow shade. This hints that while it would seal away the demons for good, the Golden Honmoon was not the solution to stopping Gwi-Ma and helping Rumi, but instead the reforged Honmoon made by HUNTR/X being vulnerable, honest and forgiving of each other. What's the color of the new fortified Honmoon? An iridescent neon rainbow.
    • During the intro, Zoey's fans say Zoey, despite her cheerful eccentricities, is known for when she gets angry... and when she does, she's VERY angry. This fuels the Poor Communication Kills-induced Plot-Mandated Friendship Failure: when Jinu outs Rumi as a half-demon, Mira and Zoey confront her, betrayed that Rumi is an enemy they swore to destroy. Rumi's attempts to explain that she was working with Jinu — who, thanks to Rumi not being forthcoming about his reluctance to serve Gwi-Ma, only know he is Gwi-Ma's top lieutenant and is working on a plan to break the Honmoon and summon Gwi-Ma to kill untold amounts of people — results in Zoey angrily cutting Rumi off before she can fully explain it was to fix her demon patterns. Rumi can only panic and babble about them being together, which makes Zoey even angrier; Rumi is reduced to frantically begging her disgusted teammates to not leave before screaming demonically, solidifying their downfall.
      "How can we 'be together' if we can't tell your lies from your truths, RUMI?!"
  • Frantic Object Concealment: Rumi does this to hide Derpy in her room when Mira came inside to talk to her. Rumi hastily hides it under a sheet and sits on it like a beanbag chair.
  • Free-Fall Fight: When their private plane gets trashed, HUNTR/X is forced to skydive without parachutes and continue fighting the demons in mid-air until they all land at the concert stage.
  • Freeze-Frame Bonus:
    • When HUNTR/X decide to finish their instant cup noodles before jumping out of the destroyed plane, you can see that they're eating out of licensed special cups with their faces and names on them, respectively.
    • When the Saja Boys are introduced in the demon world, Mystery's close-up shot reveals his fangs for a split second.
    • In the music video for “Golden”, one of the fake Twitter posts is by Maggie Kang, the director of the movie.
    • When Mira throws some darts at a dartboard with Jinu's face on it, the camera pans out to reveal a number of additional notes about the Saja Boys lining the walls, including some gems clearly written by Mira and Zoey like "UR NOT SO HOT", "DOESN'T WORK, THEY ARE HOT","DON'T MENTION THEIR GOOD LOOKS!" and "DO NOT GET DISTRACTED BY VERY HANDSOME FACES + BODIES". There's also a sticky note to the far right of Jinu's photo which has "TAX EVASION" written on it.
    • Rumi's mother's name is never spoken aloud, but the hangul written on tombstone reveals her name was Ryu Mi-Young.
    • In the fan meet event, Zoey briefly bites her lip twice when her crush (Mystery) sits beside her. It's more noticeable when she giggles and asks "Wassup?"
    • When the Saja Boys address the fans and announce their next show after HUNTR/X broke up during the Idol Awards, the screen briefly glitches and shows silhouettes of their demon forms sporting Slasher Smiles.
    • When HUNTR/X quickly apply make-up to hide their demon hunting injuries from Bobby, you can see Mira and Zoey using identical purple mirrors, while Rumi has a differently shaped black one. Why? Because she casually tossed away her purple mirror during "How It's Done".
  • Funny Background Event: Romance spends most of his time in the joint fan meet event seductively staring at Mira, even if the camera angle changes at one point and moves them to the background.
  • Gambit Pileup: All the Hunters want to seal the Honmoon. But, Rumi is lying to her teammates so she can uncover the truth about demonkind, and Celine is lying to protect her daughter from Celine's students. Similarly, all the demons want to destroy the Honmoon, but Jinu is having an internal crisis that leads him to switch to good at Rumi's behest, and then he switches to evil again secretly, and then he switches to good at a critical moment of the final battle.
  • Genre Roulette: Reflecting the diversity within Korean Pop Music, the film’s soundtrack incorporates multiple subgenres and influences with no two songs sounding similar to one another.
  • Glamour Failure: Downplayed. The Saja Boys look like normal humans, but mid-dance, the girls see their Mark of the Supernatural briefly appear, revealing them to actually be demons. When they're addressing their fans after the HUNTR/X breakup, the screen briefly glitches to show their true forms.
  • Glamorous Wartime Singer: The opening Progressive Era Montage shows that the hunters of the 1940s were a trio of Korean chanteuses modeled after their counterparts in Europe and America.
  • Gluttony Montage: Around the start of the movie, HUNTR/X partake in carb loading to prepare for their last concert of their world tour. They all ravenously go at their food, Rumi even shoves a whole uncut gimbap down her throat without chewing.
  • Gold-Colored Superiority: The Golden Honmoon will supposedly be able to keep the demons out of the human world forever.
  • Good Colors, Evil Colors: Rumi's demon marks. Initially, they are purple, glowing red when she loses control. But once she accepts her demon lineage, they turn silvery-white, glowing neon rainbow.
  • Goo Goo Getup: The Saja Boys make an appearance on a game show, where they dress as babies, sit in oversized highchairs and wear bibs with their names on them while competing to see who can drink the most hot sauce. When Baby Saja wins, he says in a deadpan tone of voice, "Goo goo ga ga."
  • Gratuitous Foreign Language: Zig-zagged. Like a lot of Korean Pop Music, the music in the film primarily has English lyrics with some Korean thrown in at intervals, which would make it Gratuitous English as in real life since the film's meant to be taking place in Korea. However, since it was made by Sony Pictures Animation for a predominantly Western audience, the inverse actually ends up being true and the Korean lyrics are the outliers instead.

    Tropes H to P 
  • Half-Empty Two-Shot: In "Free", Rumi's first stanza is full of takes in which she starts in the center, then slowly walks toward either side of the camera until Jinu, who is reluctanly ambling behind her, enters the frame as well. The song is all about her trying to reach out to him to form a genuine Commonality Connection, so it makes sense that we go from half-empty takes to two-character shots. This also happens in Jinu's stanza after the first chorus; however, the frame is such that not only Rumi accompanies Jinu, but also the latter's demonic reflection, representing the chains Gwi-Ma still has on him.
  • "Hell, Yes!" Moment: During the concert at the beginning the Honmoon starts to turn golden, leading to Rumi's reaction of, "oh shit it's actually happening," quickly joined by Mira and Zoey, the realization that they have just about beaten Gwi-ma once and for all. Hence Rumi's push to release Golden, one more push and they are done, they win.
  • "The Hero Sucks" Song: "TAKEDOWN" is turned into this by demons disguised as Mira and Zoey against Rumi. They didn't even need to change the lyrics, since the anti-demon sentiment also applies to Rumi's secret half-demon heritage.
  • Heroic Sacrifice: Jinu dies protecting Rumi from Gwi-Ma's flames, though not before his sacrifice restores his soul, which he then gifts to Rumi — allowing her to power her sword up enough to vanquish Gwi-Ma.
  • Heroic Second Wind: After finally coming to terms with her demon heritage, Rumi takes up her sword and marches into the stadium, crashing the Saja Boys' concert/soul stealing ritual by singing "What It Sounds Like". This snaps Mira and Zoey out of the demons' spell and they join in, with the three huntresses uniting in the middle to kick demon ass together once again.
  • Heroic Self-Deprecation: Despite having literal hordes of fans and being "pop-star royalty" (according to one of them), on top of being one of only three people standing in the way of the human world being overrun by demons, Rumi still believes herself to be a "mistake" due to her half-demon heritage.
  • The Hilarity of Hats: Sussie wears a small gat hat that's just the right size... which was meant for Derpy. So Jinu literally made a comparatively teeny-tiny hat for Derpy.
  • Hoist by His Own Petard: The song "TAKEDOWN" was composed by HUNTR/X to be a diss track to the Saja boys to expose them as demons. In the idol awards, Jinu uses that song to expose Rumi as a half demon and break apart HUNTR/X.
  • Hope Spot: After singing with Rumi finally silences the voices in his head, Jinu decides to go along with her plan to leave him on the other side of the Honmoon so he can finally be free. Then Gwi-Ma reveals that he knew their plan all along and torments Jinu with his guilt until he breaks and falls back in line.
  • Horrifying the Horror: Played for Laughs twice:
    • In the intro, as the girls devour their pre-show meals. The strange faces and total lack of table manners they display while devouring their food manages to unsettle the demons masquerading as private jet attendants.
    • Zoey squeeing over Mystery Saja's real face, declaring him to be her type, and then nonchalantly murdering him makes Abby and Romance pause from their own fight with Mira to stare in shock. Mira is staring, too.
  • Human Hammer-Throw: During the Hard-Work Montage/"On Patrol" Montage of HUNTR/X trying to complete "TAKEDOWN" and doing their demon hunting duties (all while "TAKEDOWN" is being played), Mira does this to a demon and the sounds of it bouncing on surfaces gave her inspiration for the song's beat.
  • Hypocrite Has a Point: Jinu taunts Rumi for not telling her friends about her patterns… without telling her about the real version of his backstory, where he abandoned his family. Nevertheless, it didn't make Rumi's decision to keep secrets from the band any less harmful in the long run.
  • Hypocritical Humor: Much humor can be derived from Mira and Zoey (especially Zoey) saying how much they don't like the Saja Boys — and then immediately crushing on them right afterwards.
    Zoey: "We can get back to the important stuff, like the fans." (sees shadow of a group of people) "Fans!"
  • "I Am Becoming" Song: What It Sounds Like completes Rumi's character arc, as she has come to accept her demon heritage and renews her bond with Mira and Zoey, and the three emerge stronger than before, taking down Gwi-Ma and the Saja Boys and restoring the Honmoon.
  • "I Am" Song:
    • "How It's Done" introduces the band and shows them in action against a group of Mook demons.
    • "Golden" for Rumi is about her coming to grips with her identity and making the most of her powers.
  • I Am Not Shazam: In-Universe. The fake flight attendant, who turns out to be a disguised demon, calls Rumi "Ms. Hunter...ix", even though that's the name of the group and not her surname.
  • I Cannot Self-Terminate: Once Rumi's demon heritage is exposed and she's rejected by Zoey and Mira, it seems Gwi-ma is set to win. A tearful, traumatised Rumi confronts Celine to beg her to kill her, even offering her sword to do so.
  •  I Have No Son!:
    • Mira's family have disowned her, and from all accounts, they loathe her. Mira uses it for her Bad Girl Rebel image, but Gwi-Ma's Mind Rape of her during the Darkest Hour reveals she's still traumatized by it, which makes her rely on her family of Rumi and Zoey, and subsequently makes it easy for her to be enthralled by Gwi-Ma when he points out she lost two different families.
    • Played With: in the Darkest Hour, Celine still clearly loves Rumi — refusing to grant her request of Suicide by Cop and doing her best to comfort Rumi. Unfortunately, she loathes demons as much as she loves Rumi, and can't bring herself to properly hug her adoptive daughter, let alone look her in the face when Rumi tearfully asks why Celine couldn't love all of her. Her idea of bringing HUNTR/X back together is by pretending Rumi isn't a demon and that it was a test — something that wouldn't work on Zoey and Mira, who KNOW for a fact Rumi is a demon after Rumi unintentionally damaged the Honmoon with her demonic powers.
  • I Know What You Fear: Gwi-Ma lures in both new recruits and new morsels by breaking them with a combination of speech and Mind Rape about their deepest, darkest fears, then following it up with Your Heart's Desire. He converted Jinu by offering the poor musician a way out of the poverty and starvation he despised, at the cost of condemning his mother and sister to even worse poverty. The resulting guilt makes Jinu willingly serve Gwi-Ma in exchange for wiping the memory of betraying his family — and the moment Jinu has second thoughts about the EvilPlan due to Rumi reawakening his conscience, Gwi-Ma forces Jinu to relive that memory until Jinu complies. Later, once Jinu is able to expose Rumi as a half-demon and break up HUNTR/X, he enthralls Mira, Zoey, Bobby, and possibly all of Seoul with their worst fears: Mira, who was rejected by her biological family and just had her found family fall apart with Rumi's apparent betrayal, is told she does not and never has deserved a family, causing her to dejectedly rebuff Zoey when she's trying to ask Mira what to do now that Gwi-Ma is poised to win — and Zoey falls next, with Gwi-Ma confirming her fear that she's "too much and never enough". Unlike Mira, he does give Zoey her greatest desire: somewhere to belong, and she numbly accepts his offer. He does the same with Bobby, telling him he failed to save the girls and that he's now alone, but he doesn't have to be. Of course, the promise of what they want is actually him eating their souls.
  • Immediate Self-Contradiction: During the joint HUNTR/X-Saja Boys signing:
    Zoey: (pissed) I am NOT sitting next to NO SAJA BOY—
    (Mystery sits next to Zoey)
    Zoey: (reduced to a giggling, blushing schoolgirl) —heheheh, wassup...?
  • Improvised Weapon: During the airplane fight scene, Mira uses a vacuum flask to hit and embed a demon to a seat. She then passes that flask to Zoey who also quickly whacks two other demons with it.
  • The Incomparable Bliss of Low Cuisine: The HUNTR/X girls are rich popstars and live in a 50-story-tall tower, but their favorite snacks are simple things like 3-minute instant rameyon noodles and gimbap, a Korean seaweed/rice/vegetable roll similar to sushi.
  • Inelegant Blubbering: Simultaneously Played for Laughs and Played for Drama. After the Darkest Hour that drove them apart and Gwi-Ma's defeat, HUNTR/X finally get to relax in a bathhouse. Zoey professes she was glad that Rumi didn't die, before breaking down into ugly sobbing that the girls mean so much to her, which causes Rumi and Mira to near-immediately break down too. Mira even tries bravely holding it in.
  • Innocently Insensitive: The “Takedown” song is supposedly meant to be a diss song towards the Saja Boys (the demon boy band) where its lyrics are filled with hatred towards demonkind. At first Rumi is aboard with the plan, until after reading it, and taking into account her insecurities over her demon heritage (something that she keeps secret from her friends), which is not helped by her growing relationship with the leader of the rival group, Jinu, she feels understandably uncomfortable with it.
  • Instantly Proven Wrong: After the "Golden" debut concert is cancelled:
    Zoey: I'm sure everything will be fine. Bobby can handle it. (her phone rings; she answers it) Hi Bobby!
    Bobby: Girls, I can't handle this!
  • Insult Friendly Fire: A lot of Mira and Zoey's comments about demons make the secretly half-demon Rumi uncomfortable — especially the lyrics to "Takedown" ("a demon with no feelings don't deserve to live, it's just so obvious") which Rumi doesn't like at all.
  • Internal Reveal: The audience learns Rumi's secret before it comes out within the story. In a supreme act of cruelty, the Saja Boys lure Mira and Zoey away from the girls' performance and impersonate the two on stage. Then they use "Takedown" as a way to crush Rumi's spirits, making her think her best friends are exposing her and rejecting her as they tear apart her jacket and reveal her patterns. The actual reveal moment for the bandmates comes after Rumi flees the stage and finds the real girls. It's not made clear what the audience thought of the scene other than it being a band breakup. Rumi is protected by The Masquerade, with the reveal of her patterns evidently having significance only to the other members of HUNTR/X.
  • Intro Dump: This is done in the style of a montage of fan interviews talking about their favorite members of HUNTR/X.
  • Invincible Hero: This becomes a plot point that propels the plot of the film. The girls are utterly untouchable by the demons at the start of the film, and it's stated that Gwi-Ma has repeatedly sent teams of demons to try to kill them - all to zero success. As a result, Gwi-Ma is forced to fight the girls indirectly, relying on the Saja Boys weakening the Honmoon by drawing away fans, rather than a head-on fight with HUNTR/X.
  • Invisible to Normals: The Honmoon can’t be perceived by normal humans, as demonstrated in one scene when HUNTR/X and Bobby are both looking out the same window at the city. All Bobby sees is a peaceful city, but Rumi, Mira, and Zoey can see the damaged Honmoon that blankets it. Notably, demons are not invisible to normals, but tend to be written off as cool costumes or next-level special effects for next-level music shows.
  • Ironic Echo:
    • Rumi, lamenting over her demon heritage, asks herself how she can fix the world if she can't even fix herself. By the climax, Gwi-Ma, witnessing Rumi with her demon markings exposed, mocks to her how she thinks she can fix the world, even though she can't even fix herself. The same thing Rumi asked herself after the failed "Golden" rehearsal.
    • In one of their secret meetings, Rumi opens up to Jinu, confessing that she views herself as a mistake due to her half-demon nature. Later on, the demons who impersonated Mira and Zoey to sabotage the Idol Awards maliciously echo Rumi's own confession back at her. Eventually, Jinu is revealed to be the mastermind behind the latter incident.
      Rumi: But I am a mistake. Have been since the moment I was born.
      Demons: You're a demon. A mistake. You have been since the day you were born.
  • Ironic Echo Cut: Bobby's attempt to cheer the girls up before a concert.
    Bobby: Visualize there's not ten thousand fans at the door screaming and sounding really scary.
    (Cut to right outside the venue where the fans are working themselves into a frenzy)
    Security Guard: Mayday! Mayday! There's ten thousand fans at the door screaming and sounding really scary!
  • Irresponsible Mentor: The main characters were trained in the ways of being K-Pop idols and demon slayers by former hunter and idol Celine. For the most part, she succeeded in turning the girls into skilled performers and warriors, but her own Fantastic Racism towards demons kept her from fully giving her half-demon student and daughter figure Rumi the love and support she needed, encouraging her to hide her heritage from her bandmates. This leads to the inner turmoil that causes Rumi to lose her voice, her friends once her secret comes out, and a Calling the Old Man Out moment while the demons nearly succeed in their plan.
  • Is This a Joke?: Gwi-Ma expresses this when Jinu proposes a new idea to stop the Golden Honmoon in form of a "demon boy band" with the Saja Boys, laughing in amusement with some demons among the crowd sharing his skepticism. However, the ruler of Underworld concedes when the Saja Boys display their new faces via glamour as handsome K-Pop stars.
  • It's Personal: When the "Saja Boys" begin to overtake HUNTR/X as the new #1 K-Pop band in the country with the latter's fanbase turning their attention to the demons in disguise, the heroines take it personally and vow to defeat them in battle and on stage.
  • "I Want" Song: "Golden," which, according to the soundtrack's executive producer Ian Eisendrath, fills this role in traditional musical film structure. The song explores each of the girls' purposes while also dwelling on Rumi's inner thoughts, including her want to be free of her patterns — her half-demon heritage — and just be the normal, human idol the world perceives her to be.
  • I Will Show You X!: Rumi's opening line of "How It's Done":
    "You came at a bad time, but you just crossed the line. You want to get wild? Okay, I'll show you wild!"
  • Karma Houdini: Possibly for Baby Saja, since he probably gets away from getting defeated by HUNTR/X offscreen nor faces his fate.
  • Kill the Cutie: Heavily implied when a soul-sucking demon appears behind the Bespectacled Cutie kid who shipped Rumi and Jinu, as her soda can drops to the ground.
  • Know When to Fold 'Em: As their plan is to beat HUNTR/X on the charts, not the field of battle, and under no delusion that they'll succeed where everyone else failed for centuries, when the girls track Jinu and the Saja Boys into a bath house, they summon weaker demons to buy time while they escape. Aftwards, they always make sure to stay out in the open and in public, where HUNTR/X won't dare attack.
  • Knuckle Cracking: Mira cracks her knuckles before HUNTR/X fight the demons inside their private plane, and just as "How It's Done" starts playing in the background.
  • Kubrick Stare: During the Idol Awards, the demons impersonating Mira and Zoey sport evil stares framed like a Stanley Kubrick villain.
  • Lampshade Hanging:
    • Despite being hostile towards the Saja Boys, HUNTR/X verbally admit "Soda Pop" is Actually Quite Catchy. The demon king Gwi-Ma himself also says a similar comment even though he initially doubted Jinu's plan.
    • While watching the "Soda Pop" performance in public, Mira points out the Saja Boys' ability to create tangible projectile kisses.
      Mira: They can make hearts out of thin air?
    • Jinu's pet bird wears a hat, which Rumi lampshades upon seeing it for the first time.
      Rumi: Is that a bird wearing a tiny hat?
  • Legacy of the Chosen: HUNTR/X are the latest in a line of all-female trios who live dual lives as famous singers and demon hunters. Brief flashbacks show the original Hunters in traditional Korean dress, then women from The Roaring '20s, a trio of Glamorous Wartime Singers, a group from somewhere between the late 60's and mid-70s, a first-generation K-pop group (including Celine and Rumi's mother), and finally HUNTR/X themselves in the 2020s.
  • Let's Duet: The song "Free" is sung by Rumi and Jinu as a Duet Bonding over their shared angst relating to their demonhood, and how they've only ever been able to confide in each other about it in a way that allows them to move on from their shame.
    Jinu: I...I don't hear his voice!
  • Letters 2 Numbers: There's an idol group named SOCI8TY who's also competing in the top charts. Their name is clearly shown overtaking HUNTR/X in the rankings when the latter drops down after being sabotaged during the Idol Awards.
  • Light Is Good: When HUNTR/X reunites for their Heroic Second Wind, the black on their clothes turn white, with the renewed strength granted by their fans manifesting as a rainbow fluorescence. Rumi's patterns also turn from purple to white.
  • Line-of-Sight Name: Rumi names the diss track against the Saja Boys as "TAKEDOWN" after hearing Mira say the phrase "take down" out of frustration.
    Mira: Okay, enough! I'm taking these down! Just like how we're gonna take down these boys!
    Rumi: Take down? Takedown! That's the song! It's a takedown!
  • Lipstick-and-Load Montage: After the Saja Boys' debut, HUNTR/X do this (which is also a Lock-and-Load Montage) to prepare to ambush them at the Show Within a Show Variety Show Play Games With Us!
  • Logo Joke: The crowd from HUNTR/X's "Final World Tour" concert is heard as the Sony Pictures Animation logo appears.
  • Loony Fan: Jinu and Rumi both sign a poster for a bespectacled fangirl who eagerly believes them to be an item — even wearing a T-shirt with crude fanart of the two. Naturally the two singers are a bit unsettled...
  • Lyrical Dissonance: The Saja Boys' song "Soda Pop", as while the tune is catchy and upbeat, the lyrics are actually about the demons wanting to consume human souls like drinking a soda pop.
  • Magic Music: The songs of the hunters empower them in battle and inspire their fans, which enables them to erect the Honmoon to keep the demons out of the human realm. As "Your Idol" reveals, the demons can do the same thing, but the other way around, crushing people's spirits to make them willingly walk into Gwi-Ma's fire.
  • Manchild: As a gag during a Korean talk show, the Saja Boys all get put into infantile outfits during a Hot Ones-style spice-eating contest. Baby Saja lives up to his name by winning and sarcastically saying "goo goo ga ga".
  • Mark of the Supernatural: In their true forms, the Saja Boys have tiger-like stripes on their arms and faces. Demons in general have these patterns and they seem to expand the more influence Gwi-Ma has over them. Rumi herself inherited patterns from her demon father and is very anxious about keeping them hidden.
  • The Masquerade: For years, generations of the hunter trio have kept their activities of demon hunting and maintenance of the Honmoon secret by passing themselves off as mere singers to the public. In the present day, HUNTR/X are able to pass off their impromptu skydiving and killing the demon infiltrators on stage as part of the "special effects" at the beginning of the film.
  • Meaningful Background Event:
    • The old man who scolds HUNTR/X for entering the men's bathhouse gets his soul sucked by a demon just after the trio leaves and closes the door.
    • Gwi-Ma starts manifesting physically in the human world when Baby Saja raps his solo part in "Your Idol". He then becomes a part of the concert's "special effects" until it's made clear that the Saja Boys are luring the audience towards his flaming maw.
  • Meaningful Echo:
    • Early in the movie, Mira and Zoey are upset that they can never go to the bathhouse with Rumi due to wanting to hide her demon scars out of fear of losing her friends. In the end, they finally are able to go to the bathhouse with Rumi who's comfortable enough to show her scars while Zoey and Mira express relief in how they're still friends.
    • Another example is how Zoey and Mira hope to start their break in their couch but end up in tears after Rumi releases the "Golden" single, thus interrupting their break. After defeating the demons and restoring the Honmoon, the girls express eagerness in going back to the couch but collectively agree to continue working when they see their fans in public.
  • Meet Cute: Parodied and Subverted. Jinu is introduced after body-checking Rumi in such a way that her tonics go flying, complete with slow-mo, romantic music and romantic lighting in a way that is clearly meant to set up a classic example of this trope. Then Jinu looks like he's extending his hand to help Rumi up before rescinding it at the last second and telling her to "watch yourself" before walking off. Behind the scenes, the crew would call this sequence the "Meet Ugly" instead.
  • Mickey Mousing:
    • In the official trailer, the beats of "How It's Done" are often synced with some on-screen actions. This is best shown around the 2:00 timestamp when Rumi fights Jinu in the bathhouse.
    • In the movie itself, the fight scene in the plane is synced to "How It's Done" as HUNTR/X beats up the demons to the beat of the music, such as Mira beating a demon into a plane seat and some demons being slammed into the plane's windows in time with the song's beats.
    • Inverted during the fight montage as HUNTR/X are also trying to compose "Takedown"; Mira kicks a demon so hard it bounces off multiple walls, and is suddenly inspired by the resulting rhythm.
      Mira: Wait, that's the beat!
  • Mid-Battle Tea Break: While HUNTR/X skydives and free-falls from their plane, Zoey takes a moment to touch up her makeup, and does so for the demon as well. They take a selfie before landing and continuing the battle.
  • Mid Word Rhyme: In "What It Sounds Like," Rumi sings,
    "My lies all collided.
    I don't know why I did-
    n't trust you to be on my side."
  • Mind Rape: Gwi-Ma controls his subjects by amplifying their fears and failures until they're shells of themselves unable to do anything but what he wants, thematically tying into the film's concepts of shame and hiding:
    • When Jinu seems to be turning over a new leaf, Gwi-Ma mockingly forces him to relieve the memory of what Jinu actually lost when he made a deal with Gwi-Ma for a life of comfort: abandoning his sister and mother into even WORSE poverty. Jinu is traumatized into going along with Gwi-Ma's plan against Rumi and the rest of HUNTR/X, and when Rumi confronts Jinu about it after "Takedown", Jinu is noticeably broken and fatalist — a far cry from his flirting with Rumi.
    • Gwi-Ma later enthralls Bobby, Mira, Zoey, and all of Seoul by amplifying the despair from HUNTR/X's breakup and their worst fears having come true — Bobby is now alone, Mira lost two families she feels she doesn't deserve, and Zoey is "too much and never enough", making them all willingly march to their deaths at Namsan Tower.
    • Rumi's story arc has her being raised believing demon heritage is shameful. This drives her obsession to turn the Honmoon golden, has Jinu gaslighting her into believing that demons maybe aren't so bad, resorting to devious methods to stop the Saja Boys, editing then abandoning the diss track then unwittingly having it used against her. There's even a Shameful Strip near the end!
  • The Mirror Shows Your True Self: A Downplayed example occurs briefly during the song "Free", where Jinu catches a glimpse of his reflection in a window while he's in his human guise. Rather than showing his fully demonic form that we saw in his introduction, the reflection shows him human except for his Supernatural Gold Eyes, which are the brightest in the dark.
  • Mood Whiplash: The scene from the trailer where the Big Bad Ensemble announces to the other demons that they will eliminate the demon hunters by using a new strategy; cut to them transformed into a boy band and doing a song-and-dance number before the crowd and the heroines.
  • Mook Chivalry: Downplayed when Gwi-Ma summons a horde of demons to fight the Hunters in the climax. They don't attack the girls one at a time, but they don't go into the audience to target the fans or attempt to surround the girls either.
  • Mook Horror Show: The group of demons posing as the personnel of HUNTR/X's private plane are on the receiving end of this by the heroines in the middle of "How It's Done", forcing them to trash the plane (which doesn't work) only to continue to get slaughtered.
  • Multilingual Song: The English versions of the songs (which are, in-universe, K-pop hits) are mostly in English with the occasional line in Korean.
  • Multiple Reference Pun: In addition to the Saja Boys' group name being a Double Entendre in Korean as "Saja" means both "lion" and "messenger of the underworld", viewers fluent in Malay or Indonesian may also find it to be an Ironic Name as "saja" means "only" or "just", like their group name implies that they're only/just normal human boys when they're actually demons in disguise.
  • Mundane Solution: In response to the heroines' constant interference, a group of male demons decide to form a boy band called the "Saja Boys", rise their way to fame and popularity and draw the populace towards them, which would lead to the girls losing their relevance in the K-Pop business while weakening the Honmoon, the magic barrier that draws energy from the Huntr/x's fans to keep demons in the underworld. The demon king Gwi-Ma is actually impressed by how well the plan works despite initial skepticism, musing that their debut song "Soda Pop" is quite catchy.
  • Musical Assassin: Averted entirely, despite the premise of the movie and the words "slaying demons with our song" being part of the Hunters' motto. While the magic of music plays a big role in the movie, it is exclusively used to maintain the barrier sealing the demons out of the mortal world (by HUNTR/X) or to dominate humans (by the Saja Boys). When it comes to actual combat, you won't see anyone throwing sound waves around - the girls rely on their martial arts and enchanted weapons, and the demons, despite being armed with unholy magic, primarily wage battle with their claws, with Gwi-Ma's fire breath in the climax being the only true magical attack in the entire movie.
  • The Musical: Though it lacks some of the trappings of a traditional musical, like dance numbers; though it has certain things that musicals (with their origin in live theatre) typically don't have, like elaborate action setpieces; and though its music doesn't come from the Western tradition, KPop Demon Hunters uses its songs for character development and plot development — exactly the way musical theatre does.
  • Musical World Hypotheses: A mixed blend of flavors. Every main character who sings in the film is magical, giving the musical scenes a lot of leeway, and HUNTR/X are shown to have enough spontaneous chemistry during songwriting sessions that it's believable this and their magic combined allow them to improvise full numbers on the fly, but the songs still vary on how diegetic they are.
    • "How It's Done" starts with HUNTR/X singing to nobody but themselves and the demons they're fighting, then finishes as a diegetic onstage number as the girls arrive at the concert; it's not clear if the song was prewritten, but the crowd chanting along with "HUNTR/X don't miss!" implies it's an established song for the group. There is a brief moment where vocals play while HUNTR/X aren't shown singing them, when the plane is falling apart and the band is silently watching.
    • "Golden" is clearly established as a prewritten composition, and is performed in a montage scene during the single's rollout, as well as diegetically onstage later at the awards show.
    • "TAKEDOWN" is also established as a prewritten track, being composed during the film's plot. It's heard in a montage scene and in brief rehearsal and Rumi sings parts of it while wrestling privately with the lyrics. The song is more fully performed both for mood as a fighting soundtrack by the team and as part of a concert performance by Jinu's demons impersonating Zoey and Mira to antagonize Rumi and expose her secret.
    • "Free" is sung by Rumi and Jinu and is fully emotional and spontaneous, as is typical for a Final Love Duet. There are also possible elements of All In Their Heads, since there's a noticeable point in the song where neither character is singing, but the vocals continue to play.
    • The Saja Boys otherwise aren't confirmed to have HUNTR/X's capacity for musical spontaneity, as "Soda Pop" and "Your Idol" seem pre-prepared, and even Jinu's song to Gwi-Ma in his first scene could have been rehearsed.
    • "What It Sounds Like" is unambiguously spontaneous, being started by Rumi and completed by Mira and Zoey as a showstopping composition they didn't prepare, showcasing the power of the hunters. (A line even calls it "The song we couldn't write," referencing both its spontaneous nature and that writing the perfect song for this moment had occupied much of the plot, with first "Golden" and then "Takedown".) When the audience joins in on "What It Sounds Like", it's possibly magical, but also explainable as picking up on an established refrain that any crowd would grasp during the first-time listen of an ongoing song.note 
  • My God, What Have I Done?:
    • After her demon heritage is exposed to Mira and Zoey, who were hurt she didn't trust them with the truth thanks to Celine's teachings and not for what she's been hiding, Rumi finally realized how wrong it was to hide her demon half from her friends as it ended up pushing them away.
    • Mira and Zoey also have one when they ended up breaking Rumi when they found out that she is half demon and gets defensive with their weapons pointing at her.
    • Celine's last talk with Rumi ends with Celine falling to her knees in despair when Rumi bitterly declares that she is glad to see the Honmoon destroyed after Rumi realizes Celine can't bring herself to fully love Rumi. In that moment, Celine likely believed she broke her adoptive daughter, and that the Hunters' centuries of effort against Gwi-Ma have gone to waste.
  • My Greatest Failure: The Darkest Hour sees Jinu driving HUNTR/X apart after exposing Rumi as a half-demon; subsequently, Gwi-Ma is able to prey on Mira, Zoey, and Bobby's fears and grief that the best thing that happened to them is now gone: Bobby couldn't keep the girls together and is now alone, Mira believes she never deserved a family, and Zoey is both too much and never enough. Lucky for them, Gwi-Ma has a solution: giving them a place they can belong to... which is getting their souls eaten.
  • My Significance Sense Is Tingling: Unlike most people, Hunters (and the audience) can perceive the Honmoon, usually as thin, glowing blue lines coating the environment. When deep pink-purple ripples through this pattern, it alerts the Hunters that a rift in the Honmoon is permitting demons to enter the world. This is why Rumi's high emotions as her demon half grows causing the same effect freaks her out so much, and frightens Mira and Zoey when Rumi does it in front of them.
  • Near-Villain Victory: By the time of "Your Idol", the Honmoon has been destroyed and everyone has fallen into despair; at the Saja Boys' concert, the enthralled audience is literally walking into Gwi-Ma's flaming maw to be devoured—including Mira and Zoey—when Rumi shows up to save the day.
  • Neat Freak: Derpy is implied to be this, giving that he's determined to make a fallen object stand up.
  • Never Say "Die": Averted, as the word has been said by Mira and Zoey twice near the beginning and end of the film.
  • Never Trust a Trailer: While the trailer does show the fun action and comedy that the movie has, the general plot of hunting demons, and the rivalry with the Saja Boys, it also doesn't show any of the more mature and intense elements of the movie, mainly Rumi's half-demon side that she tries hiding from others.
  • Nice Job Fixing It, Villain!: Even without Gwi-Ma's interference, HUNTR/X's efforts to turn the Honmoon golden were doomed from the start. But because of his interference, Rumi ended up learning how to create something stronger than the golden Honmoon.
  • The Night That Never Ends: Implied Trope. When HUNTR/X unleash a World-Healing Wave to cast away the demons' influence on Earth, which was at its zenith, the wave visibly causes Seoul to instantaneously shift from nighttime-like darkness to broad daylight, implying the demons' heightened influence was casting perpetual darkness over the city when their power over its people was strongest.
  • Ninja Prop: First there's Zoey's Wingding Eyes sequence when first seeing the Saja Boys where her eyes turn into corncobs, then pop into popcorn, which she and Mira proceed to eat out of her hat. Shortly after, during the Saja Boys' street concert, their allure is shown by them generating hearts that launch into people and knock them over. Mira grabs one and lampshades the fact that they can make hearts appear out of nowhere.
  • No Body Left Behind:
    • When the demons steal human souls, no trace of their victims are left. This is best seen when HUNTR/X are unable to save a subway train from the demons and no bodies are left inside.
    • Demons disappear completely after being killed.
  • No Endor Holocaust: In the opening, there's no concern over the wreckage of the girls' plane crashing down and killing anyone even though it was ripped apart right over a city. It's particularly bad, as it was the personal aircraft of a popular singing group (who were known to be on it when it took off); in real life, the girls wouldn't be releasing a new single, they would be spending the next several weeks - if not months - answering questions from accident investigators, with their lives both before and after the accident under a microscope.
  • No OSHA Compliance: During HUNTR/X's performance of "Golden" at the Idol Awards, Rumi rides on a circular aerial swing over the audience during her solo while secured by nothing but the grip of her hand. It looks amazing, but in real life doing this without some kind of safety harness would be incredibly dangerous and open the producers of the show to legal liability. While Rumi herself is probably perfectly safe (we've seen her skydive with no parachute and still somehow land safely), the producers aren't aware of her superhuman abilities and know in any case that audience members could be harmed if Rumi fell on them, so realistically they would never allow her to do this without appropriate safety gear.
  • Not Helping Your Case: Rumi was already having a hard time explaining herself to her friends after her demon side is exposed. But it gets worse when Rumi mentions that she was collaborating with Jinu that really solidifies their heartbreak.
  • Not My Driver: At the beginning of the film, the latest bunch of demons sent to kill HUNTR/X impersonate the crew of their private jet and then fly it away from their concert that's about to start. Apparently none of them thought to just poison all the girls' food, and even trashing the plane is implied to be an Indy Ploy.
  • Not So Above It All:
    • Mira and Zoey break out into open squealing upon seeing the Saja Boys, coupled with literally Eating the Eye Candy. Rumi calls them gross... until she sees Jinu and gets dazzled and swept off her feet by his K-drama-esque charm.
    • When Mira and Zoey express great enthusiasm to hunt down the demons by breaking into warrior roars while making comically exaggerated war faces, Rumi appears calm and composed... Until she too joins in with a roar and demented expression of her own.
    • Gwi-Ma, the King of the Underworld, admits to finding "Soda Pop", the song of the Saja Boys' debut song, catchy. He even shows up at the Saja Boys' "Your Idol" concert where he dances to their beat in front of the hypnotized audience as part of the "special effects", and even sings along towards the end.
  • "Not So Different" Remark: Jinu tells Rumi that despite her being a Demon Slayer and him a Demon of Human Origin, they are not that different from one another and he's the only one who can understand her struggles with being a Human-Demon Hybrid hiding her demonic heritage. Her initial reaction is to reject this but eventually comes around.
  • Obfuscating Stupidity: A downplayed example, but it's implied that the girls knew that the flight attendants on their plane were demons the whole time (as Rumi easily points out the unusual behaviors that the demons had been exhibiting the entire flight). The girls just pretended not to notice so that they could finish their snacking.
  • Obviously Evil: To highlight how the Saja Boys are evil, when the cameras and fans are away, they revert to a hunchback position (except Jinu) and later when they throw away the disguises, you can see that they are halfheartedly each doing their signature pose: Baby looks depressed and hateful of Mystery, Romance doesn't even bother doing more then putting his fingers together in a vague heart shape, Abby just slouches while doing a slow clap, and Mystery is too busy staring at his fingers.
  • Odd Reaction Out:
    • When HUNTR/X are facetiming with fans at their concert arena at the start of the film, one fan shows off his massive new HUNTR/X tattoo. Rumi and Zoey are weirded out by it while Mira simultaneously says an appreciative "Sick."
    • When the group catches sight of the patterns flashing across the Saja Boys' skin, Rumi and Mira say "They're demons!" Zoey says "They're magicians!", then corrects herself.
    • Rumi psyching up Zoey and Mira for taking down the Saja Boys is led by her asking what the most important event for HUNTR/X would be. Mira and Zoey respond with the Idol Awards... while Bobby asks if it's the State Fair.
  • Offhand Backhand: While fighting a horde on top of a train, Rumi kills a demon behind her without looking at it because she's preoccupied in an argument with Mira.
  • Off with His Head!: During their first secret meeting, Rumi chops off a decoy mannequin's head, mistakenly assuming it was Jinu himself.
  • Once More, with Clarity: In Jinu's first appearance, he has a memory of a mother and a crying daughter being turned away in front of large gates during Feudal Korea. It's eventually explained that he sold his soul to the Demon King for a life of luxury at the palace but in doing so cast aside his mother and sister, leaving them to fend for themselves.
  • The Oner: The film indulges in a couple of these during the finale of the bathhouse fight. The first initially follows Rumi chasing her sword that she's thrown before it moves on to the others. This is followed by a cut once Mira stabs her woldo into a demon on the ground, leading into the next one that quickly pans around the action around the woldo.
  • Our Demons Are Different: Demons are soul-sucking monsters serving the demon king Gwi-Ma who are banished from the human world by the Honmoon. They usually have iridescent purple stripes, can shapeshift and teleport at will, and have different designs inspired by many supernatural spirits from Korean folklore. Some of them were originally humans cursed into eternal servitude to Gwi-Ma after accepting his offers. There appears to be different classes of demons:
    • Dokkaebi, horned and fanged monstrous humanoids dressed in traditional clothing that make the majority of Gwi-Ma's forces. Their appearance is based on traditional Korean masks and apotropaic motifs in buildings and temples.
    • Water Demons, lanky and long-haired humanoids with abnormally long limbs and webbed hands and feet who live in bodies of water. They are likely inspired by the Mul Gwisin, restless ghosts of the drowned.
    • Humanlike demons with golden eyes and purple skin dressed in long black hanbok and wide-brimmed gat hats. They are directly inspired by the Jeoseung Saja, Grim Reaper spirits.
    • Faceless and bestial lanky demons who attack in swarms, likely inspired by Dalgyal Gwinsin.
  • Outside Ride: In the music video for "Golden", Mira is standing on top of a golden plane as she sings her solo part. The next shot then shows all three HUNTR/X members standing on top of said plane.
  • Overly Long Gag: When Derpy first visits Rumi, he accidentally knocks over her potted plant, and tries to set it upright. Instead, it keeps falling back over again... and again... and again, Derpy having absolutely single-minded focus on it the entire time. Rumi eventually steps in to fix it herself, and he starts to move closer to her, and immediately knocks the plant over again. Before he can get back in the loop of trying to fix it, she tells him to just leave it as is.
  • Painted CGI: The movie uses a 2D-3D hybrid for the animation, mixing 2D anime aesthetics with three-dimensional language. The makers of the film cited the Spider-Man: Spider-Verse movies, also from Sony, as inspiration for the movie's animation.
  • Pan: Rumi's Jump Scare prank to Jinu is delivered with the camera focusing on Jinu waiting at Gyeongbokgung Palace. The shot widens to include Rumi suddenly appearing beside him. As Jinu jumps away, yelping undignifiedly, the camera pans to the right to focus on Rumi and her proposal to defeat Gwi-Ma.
  • Paper Destruction of Anger:
    • Rumi crumpled Jinu's first invitation to meet. This is more of a determination psych up to confront him rather than of anger of him finding out her secret.
    • In the morning of the eve of the Idol Awards, Zoey tries to rip apart her notebook with the lyrics to "TAKEDOWN" after Rumi tells her she isn't feeling good with the song. Zoey is unsuccessful and just tosses it in frustration.
  • Pixellation: When Mira's fans provide an exposition of her backstory during the opening act, the faces of Mira's family members are pixelated in their two family photos.
  • Platonic Shipping: In-Universe example. When fans of HUNTR/X and the Saja Boys start shipping members of the two bands together, Baby of the latter group is the only one not paired in any romantic light. Instead, fans depict him as the surrogate son of Zoey and Mystery.
  • Playing Nice for Now: To keep up The Masquerade, HUNTR/X and the Saja Boys don't fight each other with their hunter and demonic powers out in public events such as the fanmeet. This armistice ends in the climax.
  • Plot-Mandated Friendship Failure: One that has more build-up than most examples of this trope. Throughout the movie, Rumi is terrified that Zoey and Mira will hate her if they find out she's half-demon, since they've been trained all their lives to abhor and kill demons. During the third act, Jinu's False Flag Operation exposes Rumi as a half-demon in front of the entire audience, infuriating and upsetting Zoey and Mira (not helped by Rumi accidentally implying she was betraying the team by working with Jinu to fix her demon patterns) and wind up threatening her with their weapons to make her flee. They end up almost immediately regretting it and end up falling under Gwi-ma's thrall, nearly losing their own souls in the process. They snap out of it when they see Rumi show up to fight Gwi-Ma — even as a half-demon with her patterns visible — and join up and reconcile with her.
  • Poor Communication Kills: The Plot-Mandated Friendship Failure happens when Jinu exposes Rumi's demon heritage to Zoey and Mira. Zoey and Mira have been taught to hate all demons — so when Rumi says she's been working with Jinu (who, due to Rumi not telling Mira and Zoey about Jinu's attempts at a Heel–Face Turn, only know him as Gwi-Ma's top lieutenant — which he is), Zoey angrily cuts Rumi off before she can explain she was doing so to fix her demonic patterns. Rumi's too psyched out from the False Flag Operation Jinu pulled on her to do anything more than demonically scream she can fix it — and in doing so affects the Honmoon and solidifies her demon status to Zoey and Mira, who reluctantly pull their weapons on what appears to them as Rumi being a traitor.
  • Popping Buttons: When HUNTR/X first encounter the Saja Boys, Abby's shirt buttons gradually pop off as he's flexing his muscles, and Zoey keeps Eating the Eye Candy.
  • Portmanteau Couple Name: An in universe example happens when Rumi and Jinu are secretly talking to each other during the fan meet. One of their mutual fans thinks that they're being romantic with each other, and shows off a shirt she has which combines their names, and says "Rujinu". The internet also coins "Zoeystery" for Zoey/Mystery Saja and "Miromabby" for Romance Saja/Mira/Abs Saja (whether this is rooting for a Love Triangle or a One True Threesome is unclear).
  • Post Modern Magic: Hunters are a modern, more action-oriented version of mudang, female Korean shamans who perform sacred songs and dances to honor gods, strengthen people's spirits and dispel evil.
  • P.O.V. Cam: Select shots (mostly with characters looking on their phones) and most of Jinu’s flashbacks are shown in a first-person perspective.
  • Power Glows: The Hunters and Demons abilities have a noticeable lighting that is more than metaphorical, lighting up their surroundings. In a case of Good Colors, Evil Colors, the Hunter's weapons glow blue (and gold), while the Demons and Gwi-ma's flames glow red. The Honmoon barrier also takes on the glow of whatever faction is currently affecting that area. In a more subtle example, Rumi's blade is tinged with red/purple when she's wavering.
  • The Power of Rock: The central concept of the film is that a highly select group of Korean women throughout the centuries are capable of singing so beautifully that it creates a magical barrier known as the Honmoon, which prevents demons from the spirit realm from making their way into our world. By the film's start, it has become HUNTR/X's duty to make the Honmoon golden with their song and seal the demons away forever.
  • Pre-Asskicking One-Liner: Delivered in tandem against the demons who hijacked their plane and threatened their fans:
    Rumi: Not our fans!
    Zoey: When you mess with our fans...
    Mira: We need to make it hurt.
  • Pre-Sacrifice Final Goodbye: When Jinu jumps in between the fire beam that was about to incinerate Rumi, they share a heartfelt conversation in which he apologizes for manipulating and betraying her, and she tells him she still wanted to set him free despite everything. Jinu feels he has been set free, so, as a goodbye, he gifts his soul to her to empower her enough to defeat Gwi-Ma.
    Rumi: No. I wanted to set you free.
    Jinu: You did. You gave me my soul back. And now, I give it to you.
  • Progressive Era Montage: After Celine's opening narration at the start of the film establishes how the first demon hunter trio created the Honmoon to protect the world from demons, a montage shows several different hunter trios through the decades (including Celine's own former group during the 90s, the Sunlight Sisters).

    Tropes R to Y 
  • Ramen Slurp: The girls slurp up their Ramyeon cup noodles before free-falling from the "trashed" plane.
  • Rapid-Fire Fisticuffs: Mira wails on a demon in the opening act with a flurry of punches, hitting them so fast that her arms form several smear frames despite being in 3D.
  • Reality Has No Subtitles: The Korean lyrics in both HUNTR/X's and the Saja Boys' songs aren't translated in the subtitles.
  • "The Reason You Suck" Speech: The demons enjoy this one:
  • Record Needle Scratch:
    • The song "Love, Maybe" by MeloMance plays in the background when Rumi and Jinu see and bump each other during their first meeting. But when Jinu pulls back his hand instead of helping Rumi stand up, the music is interrupted by a needle scratch, indicating that this scene is just a parody of the Meet Cute trope.
    • A tender music track plays after a young fan gives her drawing to Jinu, but the music gets interrupted by a scratch when Mira is flabbergasted by Rumi suddenly cheering for him.
  • Redemption Equals Death: Jinu dies immediately after performing a Heroic Sacrifice to protect Rumi from King Gwi-Ma.
  • Red Herring: Veering on Aborted Arc. Shortly after the hunters ditch Bobby in the middle of him talking about how he appreciates them (unbeknownst to him, to fight a demon attack), there's a brief scene of him getting a "Join The Pride" ad on his phone. Bobby smiles upon seeing it, implying he's considering quitting HUNTR/X to work for the Saja Boys. This doesn't come up again and for the rest of the movie Bobby is firmly on the girls' side (though this may be also a hint to him being the first one to be hypnotised by Gwi-Ma).
  • Reflective Eyes: When Rumi sees Jinu for the first time, there’s a brief closeup shot up her eye, where Jinu is being reflected.
  • Repression Never Ends Well: One of Celine's most important lessons is to hide all flaws, convincing the Hunters to bury their insecurities instead of looking to each other for support. This leads to the Darkest Hour when Mira's fear that she can never belong, Zoey's fear that she's too much to be loved, and Rumi's belief that her demon heritage makes her a monster cause them to break apart. Gwi-Ma also preys on repression and shames a person he won't let go of to manipulate them.
  • Rewatch Bonus:
    • Rumi suddenly coughs after HUNTR/X celebrate their World Tour, and she likewise says it was "weird" for her to cough like that. There isn't much context to explain this at first because it happens near the opening act, but a rewatch makes it clear that her voice is already getting worse at this point, as a result of her purple demonic marks slowly spreading to her neck. However, she only takes this more seriously when her voice cracks again during a practice session for their "Golden" single.
    • The villagers that the Joseon-era demon hunters save in the prologue include two figures whom repeat viewers might recognise as Jinu's mother and sister.
  • Right for the Wrong Reasons: After the Idol Awards, the audience believes that HUNTR/X has broken up onstage as the demons impersonating Mira and Zoey expose Rumi's demon patterns. Rumi does have a falling out with Mira and Zoey after the two witness her demon patterns and learn of her deal with Jinu but it's only after the onstage performance.
  • "Right Now" Montage: With "Soda Pop" and the Saja Boys going viral, they announce on social media that their fandom has reached the 50 million count. As they take turns to speak, we're shown various Joseung Saja preying on the 'Pride' and stealing their souls for Gwi-Ma. Particularly poignant is the "And to our fans, thank you. We really feed off your energy". The camera then slides from the latest victim to a news report on missing people reports having tripled, and then to a shower of souls going straight to Gwi-Ma's maw in the demon realm.
  • Rule of Symbolism:
    • The leather performance gear HUNTR/X wears for "Golden" and then the one for "Takedown" at the Idol Awards are very similar except for their colors. The "Golden" version is mostly white but covering up black tops, while the "Takedown" version is mostly black, covering up white. This reflects how "Golden" is an outwardly positive song with dark undertones about cutting out the parts of yourself you don't like (demonstrated when Rumi covers up her patterns while singing the lyrics "no more hiding, I'll be shining..."), while "Takedown" is a much darker song that takes that theme and brings it front and center.
      • The only exception to this is Rumi, who wears a black jacket over a white everything else in both "Golden" and "Takedown." Not only does this hint that she's different, being half-demon, but it also symbolizes the negative aspects her hiding what she really is, with darkness covering something beautiful. This comes to a head when she's finally confronted by Mira and Zoey about her demon heritage, in the now matching "Takedown" outfits — she's now seeing herself and her hate for her demon side reflected in her closest friends.
      • When the three finally reunite while singing "What It Sounds Like," Rumi is no longer wearing the jacket, she's finally accepted her demon side and has her patterns out for all to see. The act of reuniting also turns the black parts of Mira and Zoey's outfits white as well, symbolizing them not only accepting Rumi, but using that to accept the parts of themselves they perceived as being negative.
    • A promo for the idol awards shows a city street with one side colored blue (HUNTR/X) while the other pink (Saja Boys). If one looks on the HUNTR/X side, they'll notice some pink lights, hinting at how the demons are starting to win. Alternatively, it reflects the two parties: the Saja Boys are all demons, but while HUNTR/X are outwardly humans, at least one of them is secretly half-demon.
  • Running Gag:
    • The HUNTR/X girls collectively saying "Hi Bobby!" whenever they greet their manager. It shows how the girls all appreciate his presence, and are all on the same wavelength. The fact that they fail to greet Bobby this way while they're practicing "TAKEDOWN" for the Idol Awards speaks to the girls' cohesion coming under strain.
    • Even the most unlikely people keep finding "Soda Pop" catchy.
    • There's a fan who keeps on ripping his outer shirt to reveal another shirt underneath. He's in the audience when HUNTR/X are forced to participate during the "Play Games With Us!" show, shouting and ripping his plain shirt to reveal his HUNTR/X shirt. During the "Takedown" montage, he has a video of himself ripping his HUNTR/X shirt and switching to the Saja Boys. He appears again near the end, ripping his Gwi-Ma shirt and becoming a HUNTR/X fan once more.
  • Saving the World with Art: The main thing protecting the human world from demonic invasion is the Honmoon, a magical wall powered by unity and positive feelings. Korean idol culture is in part a Benevolent Conspiracy to generate said feelings and uphold The Masquerade. The finale shows that a single appropriately inspiring song can rebuild the Honmoon over all of Seoul in less than an hour.
  • Scary Shiny Glasses: A humorous example; an adoring Fangirl's glasses are permanently shiny as a way to convey how she's creepily excited about Rumi and Jinu whispering to each other, who are understandably freaked out and a little annoyed.
  • Scooby Stack: HUNTR/X do this pose often, vertically and horizontally. Most notable when Mira and Zoey pop out behind Rumi to get a look at the first appearance of the Saja boys, another horizontal one when they creep up at the Saja Boys' "Soda Pop" debut, and a vertical one when tracking them to the bathhouse.
  • Secret War: Unbeknownst to the human world for centuries, there is one between hunters and the demon forces of Gwi-Ma.
  • Sequel Hook:
    • The Honmoon does not turn gold by the end of the movie, nor is it confirmed if Rumi could survive that happening. What the new Honmoon does beyond forcing Gwi-Ma and the demons back, and allowing Derpy Tiger and Sussie companions to remain in the human world, is not explicitly described.
    • Speaking of the demons, nothing is revealed about Rumi's father other than that he is (or was) a demon.
    • We don't know for sure how Celine feels about Rumi embracing being a demon, though we saw that she couldn't accept it during Rumi's Despair Event Horizon.
  • Serious Business:
    • HUNTR/X are very protective of their fanbase and go to great lengths to keep their loyalty. Justified, since the love of their fans is what they need to keep up the demon-sealing barrier protecting their world.
    • They are also extremely attached to their pre-concert snack time and do not take kindly to it being interrupted by another demon ploy.
  • Shameful Strip: At the Idol Awards, the demon impersonators of Mira and Zoey remove Rumi's jacket during an impromptu performance of "Takedown", revealing the demon patterns on Rumi's bare arms. This is mostly a psychological game to make Rumi think her friends are turning on her and to destroy the Honmoon enchantment, and the real Mira and Zoey learn what's up after she flees the stage and finds them while in her most demonic look.
  • Shipper on Deck: During the joint signing, it's revealed that fans have started shipping the members of HUNTR/X and the Saja Boys together, much to both groups' chagrin.
  • Ship Tease: Quite a lot, hilariously Played for Laughs and showcased In-Universe. The chemistry between Rumi and Jinu is one of the film's plot points while Mira and Zoey are constantly swooning over Abby Saja and Mystery Saja, respectively. Just like real-life K-Pop fandoms, there's public speculation on whether the members of HUNTR/X and the Saja Boys are a thing, much to Rumi's, Mira's, and Jinu's chagrin.
  • Shoo Out the Clowns: When Gwi-Ma congratulates Jinu for betraying Rumi, Sussie is nowhere to be seen in order for the scene to focus on the drama of Derpy trying to remind Jinu of the latter's relationship with Rumi.
  • Shout-Out: See here.
  • Shown Their Work:
    • In addition to being steeped in K-pop musical traditions and having some absolutely killer songs, there's a clear awareness of music. Rumi has trouble hitting that high note in "Golden" because she's belting an A5: every actual musician who has commented on the subject has been flabbergasted at the difficulty of doing this.
    • At the beginning, one of the fan videos shows how they got a HUNTR/X tattoo, which creeps out Rumi and Zoey. Tattoos are frowned upon in Korea, and Zoey inheriting Korean culture would be uncomfortable. Mira, being the gritty rebellious member, likely wouldn't care given she's into it.
  • Show Stopper: HUNTR/X wind up constructing and performing two different utterly superhuman-sounding songs in order to seal the Honmoon for good:
    • Their first attempt, "Golden", is a song that is in essence about all of their struggles and their excitement for moving forward after fulfilling their duty, but it is also covertly a more specific song about Rumi, and the angst she feels at trying so hard to erase her patterns so that she can truly feel at peace while hanging out with Zoey and Mira. It also features some godlike high notes that Rumi can't initially hit, but effortlessly crushes when her confidence is given a boost.
    • Their second attempt, "What It Sounds Like", completely flips the script on the message of "Golden". Whereas "Golden" is about removing the parts of yourself that you hate, "What it Sounds Like" is about accepting them and growing stronger because of it. Hence, it ties in perfectly with HUNTR/X's reconciliatory performance where they defeat the Saja Boys, restore a new Honmoon and seal Gwi-Ma away forever, their unbreakable True Companions bond even stronger for it.
      My voice without the lies, this is what it sounds like!
      Fearless and undefined, this is what it sounds like!
      Truth after all this time, our voices all combined
      When darkness meets the light, this is what it sounds like!
  • Sigil Spam: Both HUNTR/X and the Saja Boys have them on some of their In-Universe merch:
    • HUNTR/X's sigil is a modified "H" monogram.
    • The Saja Boys' sigil is a head of a male maned lion. In the climax, for their song "Your Idol", it is changed to represent a demon by removing the mane and changing the ears into horns.
  • Simple Solution Won't Work:
    • The demons have spent centuries trying to destroy the Honmoon, a barrier created by the first demon hunters that prevents most demons from entering the human world. The simple way of getting rid of the Honmoon is to kill the current generation of hunters maintaining the barrier. However, the demon king Gwi-Ma, has spent four hundred years doing nothing but sending assassins after the hunters, to no avail. The opening of the film establishes that the newest batch of hunters, HUNTR/X, are a trio of Showy Invincible Heroes so trying to kill them is near impossible. The plot kicks off when Jinu proposes that instead of attacking HUNTR/X directly, they form a demon boy band to steal away what truly powers the Honmoon, HUNTR/X's fans. Gwi-Ma finds the idea utterly ridiculous, but gives the go ahead as he has no other plans of his own. It ends up being Crazy Enough to Work.
    • When Rumi reveals that she's losing her singing voice, Zoey suggests taking an extended break to let Rumi recover. Rumi shoots that down because they need to perform at the Idol Awards, which provides the most spiritual energy to strengthen the Honmoon every year.
    • After HUNTR/X realizes that the Saja Boys plan to steal away their fans thus removing the power source of the Honmoon, their first idea to counter is to just simply kill them. However, the Saja Boys know that they can't defeat HUNTR/X in a fair fight, so they opt to stay in the public eye to prevent HUNTR/X from attacking them outright, or perform a Tactical Withdrawal while using their mooks as a distraction. After a failed first outing, HUNTR/X determines that it is useless to try to go after the Saja Boys directly and instead decides to focus on winning the Idol Awards to turn the Honmoon golden, which will permanently seal away the Saja Boys and all of demon-kind back to the Underworld.
  • Sleek High-Rise Apartment: HUNTR/X lives in the near top floor of a skyscraper with a window taking up two walls and a "closet" built like a Wall of Weapons that appears to take up the remaining stories.
  • The Snack Is More Interesting: When demons hijack the plane in the beginning, HUNTR/X are mostly angry that their snack time is interrupted. They then proceed to cook and eat ramyeon while they fight, with cooking and protecting the ramyeon taking more effort for them than the fight, establishing their confidence and skill.
  • Sneaking Out at Night: Rumi does this a few times to meet with Jinu without the rest of HUNTR/X finding out.
  • Something Else Also Rises: A rare female example with Mira and Zoey. When they catch sight of Abby Saja and his muscular body, Zoey first suffers from High-Pressure Emotion, then her eyes turn into his abs, then buttered corn that explodes into popcorn while she and Mira squeal excitedly. This becomes a Running Gag.
  • The Song Remains the Same: Most dubs, ironically including the Korean dub, chose to leave the songs alone, with the exceptions being French, Greek, Hebrew, Hindi, Japanese, Brazilian Portuguese, Latin American Spanish and a few others. Weirdly, the Ukrainian dub credits list a song translator and a musical director despite the songs being left in English.
  • Songs in the Key of Lock: Being K-Pop stars isn’t just a glamorous cover story for the HUNTR/X trio — their mission also depends on them being able to use music to pump up and resonate with the crowd so much that it creates a Honmoon, a magical barrier that blocks demons from coming to the earth. Their ultimate goal, and the goal of the hunters from the first generation, is to create a song SO resonant and powerful that it will create a Golden Honmoon, a barrier so powerful and impenetrable that it will keep the demons out of the human world for good. This is also why the demons form a rival band to steal their fame, since no fans means no Honmoon. HUNTR/X think their new song "Golden" will get them this goal, and are nearly correct, but when things fall apart, Rumi leads them in a different song, building a new Honmoon with new colors, whose specific properties and potential differences from the previous Honmoon system aren't explained.
  • Soul Eating: The demons suck out human souls in order to bring them back to the Underworld and feed them to Gwi-Ma. The humans themselves vanish entirely after this is done, and it's not clear if there's any possibility of reversal or salvation for the victims.
  • Soup Is Medicine: Rumi runs off after her voice cracks during the rehearsal for the live debut concert of their new single GOLDEN. When she comes back to HUNTR/X's apartment, the other girls serve soup for her, thinking her voice crack was caused by stress from overwork.
  • Spontaneous Weapon Creation: HUNTR/X's weapons seem to be made out of Honmoon energy and are summoned when they touch the Honmoon's lines. In the climax, Jinu's soul also appears to turn into a huge sword.
  • Star-Crossed Lovers: Rumi and Jinu become this over the course of the movie despite being on opposite sides. They formed a bond from how great their deepest shame is. Their love became so deep, Jinu gave his life and soul to rescue Rumi, her friends, and the humans.
  • Staggered Zoom: Done in time to the music, no less, during the "How It's Done" sequence when the girls see the trashed remains of the plane they're standing in.
  • Stop Faux-tion: The movie is animated at a low framerate to mimic the feel of the Limited Animation in Korean anime.
  • Suddenly Shouting: After a rather disastrous concert faceoff that ended up exposing Rumi's demonic heritage which shatters her relationship with her friends, she comes across Jinu and demands whether he intentionally screwed her over, which he admits to since their relationship was a sham as he puts it, prompting Rumi to convince the demon boy that, even if he's done bad in the past, he's still a good person, especially since he tried to bring his family out of poverty. However, Jinu has not been telling her the whole truth and snaps at her attempt to reach out to him.
    Jinu: I LEFT THEM!
  • Suicide by Cop: During the Darkest Hour, Rumi, who has been exposed as a half-demon to Zoey and Mira and betrayed by Jinu to set up Gwi-Ma's total victory, despairingly demands Celine to do what should be done to demons like her: kill her.
  • Supernatural Gold Eyes: In their non-human guises, the Saja Boys have golden eyes to highlight their supernatural nature as demons. By contrast, they use otherwise normal eye colors whenever they're in public to hold up their image as an otherwise ordinary, popular K-Pop band. Rumi also sports just one when her heritage as a half-demon is exposed and she's at her most unstable, but her look balances out and her eyes return to normal once she declares her intent to make another Honmoon.
  • Sweets of Temptation: The song that rockets the boy band Saja Boys to stardom is "Soda Pop," a song about metaphorically drinking up someone's love. Like a sweet soft drink that rots your teeth out of your head, their candy-coated pastel aesthetic hides from the public that they're actually demons out to get everyone's souls and drink them up like soda.
  • Take That!: The Saja Boys could be interpreted as this to BTS. Like the Saja Boys, BTS blew up out of nowhere. JYP Entertainment, the K-Pop label behind K-Pop Demon Hunters and TWICE, meanwhile, were one of the established Big 3 companies, so it would be understandable for them have a chip on their shoulder regarding HYBE. Also like the Saja Boys, BTS is particularly aggressive when it comes to fan engagement.
  • Team Power Walk: Done twice by HUNTR/X with weapons in hand. A slow-motion version from the side as the girls approach the cabin crew demons on their hijacked jet during "How It's Done" at the beginning of the film as well as a more emphatic variant during "This Is What It Sounds Like" at the film's climax.
  • Teeth Flying: This happens to the large demon during the Free-Fall Fight portion of "How It's Done" when Rumi does a Diving Kick to his backside.
  • Tempting Fate: At the height of the film's Darkest Hour, as the masses are willingly walking into Gwi-Ma's flames to be devoured, the Saja Boys sing "No one is coming to save you!" Not even a minute after this line, Rumi arrives to save everyone.
  • The Theme Park Version: Played with. On the one hand, Jinu's past shows the starvation and tyranny that characterized some periods of Korean history; on the other, the oppressive and unsavory elements of the real Korean idol industry are absent, because the movie is an idealistic epic about the value of art and the triumph of good over evil. Unusually for the trope, many of the movie's creators (including one of its directors) were born in the country depicted and made a point of depicting its art and inventions in the movie.
  • There Was a Door: Inverted. When skydiving out of the wreck of their private jet, HUNTR/X make sure to use the door, even though the entire front of the craft is missing.
  • Trailers Always Spoil: It's easy to miss, but the trailer shows Jinu slashing Rumi's sleeve during the bathhouse fight, revealing her demon patterns. In the film itself, Rumi's patterns are revealed about fifteen minutes in, but clearly are meant to come as a complete surprise.
  • Traintop Battle: On the day before the Idol Awards, HUNTR/X responds to an attack from demons on a rapid transit and fight on top of it to try to protect the passengers.
  • Translation Convention: The movie is set in South Korea, but everyone speaks English in the original language track. Most of the performers are Korean-American or Asian-American and lend American accents to their roles, but Gwi-Ma and Jinu are voiced by Korean actors speaking English with Korean accents.
  • Triumphant Reprise: A triumphant instrumental reprise of the chorus of "Golden" is played at the end of "What It Sounds Like", just before the Hunters strike down Gwi-Ma.
  • Turned Off by the Jerkass: HUNTR/X are initially head over heels for the Saja Boys. Then Jinu rudely shoves Rumi to the ground, and the girls immediately grow revolted by these hot guys even before they learn they're a bunch of demons. Amusingly, HUNTR/X are still not completely immune to their looks even after learning the Saja Boys are demons, but they keep their heads on straight about who they are.
  • Twice Shy: Rumi and Jinu get quite close over the film, except they then also get flustered and withdrawn anytime they share an emotionally intimate scene together.
  • The Un-Reveal: During the final battle against the Saja Boys, Zoey finally sees what Mystery looks like behind his bangs and declares him to be exactly her type, but his back is turned toward the audience, who never sees what he looks like, and Zoey kills him before we get another chance to see.
  • The Un-Smile: Rumi (and the audience) can tell if someone is a demon pretending to be human by noticing their "weird" and creepy Uncanny Valley smile that's too big and wide. This applies to Rumi's smiles, too... Later Played for Drama when Rumi (and the audience) realize something is wrong with Zoey and Mira when they sport vicious and uncanny grins that are nothing like even their most smug smiles...
  • Undead Tax Exemption: Most of the time, no one seems to bat an eye at the "Saja Boys" who appeared out of nowhere and quickly rose their way to rival the heroines in the K-Pop business. However, a Freeze-Frame Bonus at the girls' Dartboard of Hate implies them suspecting or accusing the Saja Boys of tax evasion.
  • Vamoose from the Vehicle: During the film's first fight, the demons rip apart Huntrix's private jet, intending for them to die in a fiery plane crash while they eat the souls of the fans below. The girls' response? Slurp up their noodles as fast as possible, then jump out of the plane (without parachutes). The looks on their faces make it clear this isn't the first time this has happened. They even beat up demons and touch up their makeup on the way down!
  • Villains Blend in Better: On the other hand, the Saja Boys are able to fit in with human society by making themselves endearing to the public with their musical debut on the streets and later their participation of a game show.
  • Villain Has a Point:
    • Gwi-Ma mocks Jinu for acting like Rumi's plan was ever going to free him. While it's psychological abuse on Gwi-Ma's part, he's correct about their plan being extremely shaky; even if Jinu hadn't sabotaged them, Rumi had no guarantee that winning the Idol Awards would even turn the Honmoon golden, to say nothing of whether a golden Honmoon would even free Jinu or just leave him trapped with Gwi-Ma for all eternity.
    • In the same scene, he also mocks Jinu for not trusting Rumi enough to tell her the real version of his backstory. Though this is also just an attempt to shame Jinu into obedience—while letting him continue to wrongly believe that Rumi would reject him if he told the truth—Gwi-Ma is correct about the self-defeating nature of Jinu's approach: how can he free himself if he believes deep down that he doesn’t deserve happiness, and what’s the use of being accepted by Rumi if he doesn’t give her the choice to accept all of him, the good and the bad?
  • Villain Reveals the Secret: During the Idol Awards, Gwi-Ma's demons drew Mira and Zoey away, hijacked HUNTR/X's performance of GOLDEN and, with their own song TAKEDOWN, exposes Rumi's demon patterns while also stressing her to uncontrollably release her demon powers to the audience and the returning other members. The masquerade isn't broken by this, though, and the effect of the reveal only happens once Rumi meets her real bandmates after leaving the stage.
  • Villain Song:
    • "Soda Pop" hints at the Saja Boys’ nefarious intentions. It's one hell of an Ear Worm, immediately pegged as the catchiest tune on the soundtrack. It's also totally sanitized: while HUNTR/X's numbers use vocal production — tones, breaths, register, etc — to indicate hope, despair, excitement, etc, "Soda Pop" has absolutely immaculate singing, manicured almost to the point of artificiality.
    • "TAKEDOWN" plays with this trope; it is written by Zoey and was intended to be a "The Villain Sucks" Song. However, the song makes Rumi very distressed; she's reluctant to sing it due to its negative vibes and how she feels that all the insults intended for the demons are also aimed at her. And when the song is finally sung it's not by the trio, but by a pair of demons masquerading as Mira and Zoey, and Rumi's half-demon nature is forcefully exposed to the real Mira and Zoey.
    • "Your Idol" is a bombastic number about how they're using their music to corrupt the fans and destroy the world. It's got Gratuitous Ominous Latin Chanting and a fiery background (Gwi-Ma himself) to boot.
  • "The Villain Sucks" Song:
    • Jinu is introduced singing a ballad called "Jinu's Lament" where he points out how Gwi-Ma only has a fraction of his former power and is on the verge of being permanently defeated unless he listens to Jinu's plan about how to reverse HUNTR/X's magic.
      Jinu: And will he let the fire go out? Is this the end of him now?
      Dying king with a crumbling crown? Will he let the fire go out?
    • HUNTR/X's "Takedown" is about the girls wanting to take the Saja Boys down. In-Universe, it's specifically mentioned to be a diss track, but its lyrics also include mocking demons in general.
  • Visual Pun:
    • In the intro battle, Mira does a big wind-up baseball pitch to pitch a pitcher of tea into a demon's face.
    • Zoey is wearing a bucket hat when she lays eyes on the Saja Boys for the first time and gets so flustered by their good looks that her eyes turn into popcorn that rain down into her hat. In other words, her hat has become a popcorn bucket.
    • Romance's ability to create hearts out of thin air becomes a visual pun during the "Play Games With Us!" show. Unable to finish the bottle of hot sauce, Romance gives up and the heart that comes out of his mouth is visibly burning, with the host making a punchline about "heartburn" as it happens.
      Host: Looks like Romance is out due to... heartburn?
  • Voice of the Legion:
    • There are times when some of the Saja Boys briefly speak with an echo in their voices, alluding to their demonic nature. This is best heard in the latter parts of the film when Mystery thanks the fans for their support, and when Jinu suddenly shouts at Rumi after admitting he lied about his backstory.
    • When Rumi confronts Celine after her demon side is exposed during a performance, and Celine still insists on hiding her markings, Rumi's voice gets deeper and more ominous as she says "All of me!"
  • Voluntary Shapeshifting: Demons can shapeshift into human forms, as seen with the crew of HUNTR/X’s private plane. HUNTR/X themselves don’t recognize they’re demons until they start acting in abnormal ways, like watering a plant with coffee.
  • Warts and All: A major theme of the movie. The girls all have flaws and insecurities under their pop star veneers, and "What It Sounds Like" is all about accepting said flaws, namely Rumi's demon heritage, and pointedly, Rumi's patterns never go away or recede, though a balance is struck with demonic transformations like her arm and eyes being temporary and the color of the jagged patterns changing to magical pastels as Rumi accepts herself.
  • Welcome Titles: In a nonmusical variety, the HUNTR/X girls are introduced by means of what their fans know of them and why they find each girl to be cool and a role model. First off, we have Mira, her family's black sheep, who is the lead dancer and a Deadpan Snarker. Secondly, there's Zoey, a Korean American rapper who can switch from cute to badass in a second. Finally, Rumi is the main vocalist due to her prodigious voice. She was raised to be The Leader by the previous K-pop Girl Band.
  • Wham Line:
    • After revealing Rumi has the same marks as the demons that are somehow interfering with her voice and she's desperately trying to hide, a flashback gives us an explanation that changes everything we know about the demon/hunter relationship.
      Celine: You only have those because-
      Child Rumi: My dad was a demon?
    • In a case where a Wham Line is more likely to cause relief than shock, Rumi's preceding scene, and her entrance to the Saja Boys' concert, implies she's here to join the demons, one way or another. When Gwi-Ma mocks her by saying the Honmoon is gone, she agrees...
  • Wham Shot:
    • During the "Golden" montage, Mira and Zoey are shown taking a selfie in their dressing room, and then the camera pans to Rumi, alone in her dressing room. The wham moment is when she takes off her bathrobe to reveal the purple patterns on her arms which mark her as part-demon.
    • During one of the girls' attempts at filming a performance of their single "Golden", Rumi's voice suddenly starts breaking, prompting her to head to the dress room to get it together. Once there, she unzips her suit...and her patterns have spread to her neck.
  • What Happened to the Mouse?:
    • Celine isn't seen again after Rumi angrily confronts her about making her insecure about and concealing her half-demon heritage before going to face Gwi-Ma, and it's left ambiguous by the end of the film as to whether HUNTR/X kept in touch with her after the final battle.
    • For some reason, aside from the Saja Boys (minus Jinu) getting killed off by HUNTR/X, Baby Saja is the only member who isn’t shown being defeated at all. It’s unknown what happens to him, but it's likely he was either killed offscreen or managed to escape with a few surviving demons back to the demons' world.
    • The scene where the flight attendants and pilots on the plane are revealed to be demons. HUNTR/X defeats them, the plane is broken in mid-air, and the trio simply skydives off. It's never brought up or seen again, leaving one to wonder where the plane parts landed.
  • What the Hell, Hero?: Mira calls Rumi out on her continued dishonesty and secrecy towards her fellow band members, as they need to be in-sync both in the field and on-stage. Once Rumi is revealed to be a demon, Mira is hurt that she would keep a secret like that from her and Zoey despite claiming to trust them earlier.
  • Wingding Eyes: Mira and Zoey's eyes turn into throbbing red hearts when they first see the Saja Boys. Zoey, after seeing Abby's chiseled abs, has her eyes turn into six-pack abs, then ears of corn; when a button pops off his shirt (and hits her face) the button turns into a lump of butter on the corn-eyes; finally, when his stretching makes his whole shirt pop open, Zoey's eyes explode into popcorn that falls into her bucket hat and Mira proceeds to eat it. This happens to them again during their confrontation with the Saja Boys in the bathhouse and Mira during the final battle.
  • World-Healing Wave: When the Hunters defeat the demons, they sing a powerful song that rouses everyone's souls, strong enough to create the Honmoon, a protective barrier that seals away the demons across all of South Korea. This is used to great effect in the climax, when HUNTR/X overpowers Gwi-Ma and his demon army and casts a new Homnoon across South Korea and then the rest of the world, wiping away all the demons, snapping all the fans out of their hypnotism, and restoring daylight to Seoul.
  • World Limited to the Plot: The opening narration shows the anticipated Golden Honmoon as a barrier that affects several countries and is implied to spread, eventually covering the world. However, the story's focus is mostly limited to Korea; the shown generations of demon hunters who have been maintaining the Honmoon and are expected to make it golden someday are all Koreans, while some demons shown in the film are based on mythological Korean entities (such as the Jeoseungsaja). Although the United States of America got briefly acknowledged, it was mostly just for mentioning Zoey's backstory of being a Korean who grew up in Burbank, California.
  • Would Hurt a Child:
    • In the opening montage, a demon corners a mother and her young daughter with intent to take their souls.
    • In a montage of demons stealing the souls of the Saja Boys' new fans, one victim in a convenience store is an adolescent.
  • Wrestler in All of Us: In the plane fight during "How It's Done", Zoey opens the fight with a hurricanrana into an armbar.
  • Wrong Bathroom Incident: HUNTR/X follows the Saja Boys into a bathhouse, which momentarily gets Zoey excited that she and Mira finally get to go to a bathhouse with Rumi...only for it to turn out to be a men's bathhouse. After a massive brawl with a bunch of water demons, the girls are scolded by an older gentleman for that exact reason and they apologize profusely before fleeing.
    Jinu: Oh, wow. Did you really follow us in here?
  • Yellow/Purple Contrast: The yellow of the impenetrable golden Honmoon contrasts with the purple flames of Gwi-Ma. HUNTR/X wears gold-accented clothes to evoke the Honmoon and Gwi-Ma's demons have purple patterns on their skin.
  • You Are Not Alone: One of the themes of "What It Sounds Like". Rumi has realized that, in believing she had to suffer shame and isolation to hide her patterns, she's been selling her, Mira and Zoey's friendship short. The honest feelings in her singing pull Mira and Zoey out of Gwi-Ma's trance to join her, admitting they also struggle with insecurities. HUNTR/X's bonds are reforged when they declare that no matter how broken or fake they might feel, they'll always be there for each other.
  • You Can't Thwart Stage One: The first part of Gwi-Ma's plan - using the Saja Boys to win the Idol Awards and destroy the Honmoon, allowing him to manifest on Earth - ultimately comes to fruition.
  • Your Heart's Desire: In tandem with I Know What You Fear, this is how Gwi-Ma converts people — either as demons or as food. He lured Jinu in with promises of fame and fortune — by forcing him to leave his mother and little sister in even worse poverty. Now all Jinu wants is his memories erased to ease the guilt, and Gwi-Ma continuously preys on Jinu's guilt to do his bidding. Later, during the Darkest Hour, he enthralls at least Bobby, Mira, and Zoey — and possibly all of Seoul — by rubbing their failure in their face (in Zoey, Mira, and Bobby's case, that they failed to keep their Family of Choice together via their flaws) and offering them what they want (Zoey wants to belong somewhere with all her quirks and Bobby doesn't want to be alone). Unfortunately, "what they want" is instead having their soul eaten by a demon king.

Baby Saja

Despite his fellow Saja Boys and the co-host of Play Games With Us being overwhelmed in the hot sauce chugging challenge, Baby Saja is completely unfazed.

How well does it match the trope?
