Because I presume in the original japanese version the non-gendered pronoun or something was used. As we don't use [it] to describe a person the translated decided to go with [they].
Guess author want to keep the gender of Opera hidden for now.
@Nighthawlc
Yeah that what I meant. Probably did not explained probably. I actually don't even remember what were the arcs about after the vampires for some reason😀
@Qwertt
No, LN continues and as far as I heard author want to rewrite the story after the next arc (about vampires)
Interesting note is that he inspires all the girls and the men either villains or die.
