That’s what I wanna know too.
That's a choice the translations made but as far as we know Kou always identified as a girl even is she dresses like she does (Hence the fact Nifuji had to apologize for the mistake) ...
I think Kou said it was fine for everyone to call her Kou-kun (which is a more masculine honorific), so I'm guessing she/they
Are kous pronouns they/them??
