Maybe he's a trans guy?
u got it backwards i think SHE is a trans girl
At the time it was unclear, it could have been either way. Someone assigned female who was being called brother bc "he" wanted it, or someone assigned male who was still being referred to that way but expresses her/themself femininely.
As of now it is still unclear how the chara identifies, but yes as of the latest chapter we have some more info.
Im confused is the new "girl" with cool dyed hair ACTUALLY Mu Xiaoen's sis? And is the new "girl" a girl or not?
