The hero of this visual novel is transgender. The hero's "gender identity" (self-identification as woman, man, neither or both) does not match his "assigned sex" (identification by others as male, female or intersex based on physical/genetic sex).

"Transgender" does not imply any specific form of sexual orientation; transgender people may identify as heterosexual, homosexual, bisexual, pansexual, polysexual, or asexual; some may consider conventional sexual orientation labels inadequate or inapplicable to them.

He may have already made a permanent or partial transition to the opposite sex (this could be before or during the story), thus becoming transsexual.
