i'm sorry but why can't we interact if we use he/him for chihiro? his birth gender is male, and he is a male, he was just a cross-dresser, it even says so on the wiki 🧍
firstly i’d like to address that fandom wikis are just there to put information that is explicitly stated in canon or by the creators. they don’t take subtext of coding of characters into consideration, so i’d hardly consider it irrefutable evidence as to why chihiro is a boy or not
secondly, chihiro is written with harmful stereotypes of trans women in mind, and she is written by cis men. i’m sure you’ve heard the transphobic sentiment that trans women are “just cross dressing men”. it’s not surprising given kodaka’s track record with the lgbt coded characters. this is just simply how kodaka and the rest of the writers on danganronpa views trans woman, so you can understand from that that chihiro is coded as a trans woman and her storyline is undeniably transmisogynistic because of the views of the writers.
and even if you take all of that away, saying that her “birth gender is male” as part of your reasoning as to why she possibly couldn’t be a girl is flat out. not good.
i am not a trans woman myself, but i recommend you listen to trans women about tha matter such as @/00dani, who has much better formulated writings as to why chihiro is a trans woman and how the way she was written is transmisogynistic
