Creepy Crossdresser: Hargna's character design plays this to the hilt, complete with the gaudy outfit, narcissism, and Noblewoman's Laugh. But she averts it, both by identifying as female and by actually being a decent person who ultimately helps reform the underworld in the end.
I Was Just Passing Through: When the party ends up imprisoned by their supposed human allies, Hargna plays her Villainous Rescue of them off this way, saying that she has come to "take them captive" and then "carelessly" letting them escape once they're outside the base where they were held captive.
