Weird way to judge if that's a girl or not. So if you were to wear a skirt tomorrow then you would have been a girl?
Given that last page, and if there wasn't a mistranslation earlier, then odds are that it is a younger brother.
Ok? And do you think its more likely someone who crossdresses comes outside in their school uniform?
Shes also way shorter them and the shading just below her chest indicates breasts.
Atleast its more logical than believing shes a trap based on Kawashima mentioning she has a little brother.
( Which no shade to the tl team, they were clearly making jokes about it and honestly I wouldn’t really care if it were real either because really. Who am I to say no? traps can be fun and this manga could probably pull of a good one.)
But please don’t critique me over political correctness or anything.
Politics should just be that politics.
