"This isn't cosplay".. so she's a boy?
People are using the word "cosplay" wrong and I don't even bother try to correct them...
I think that's the whole point? It isn't 'cosplay' for Akira-chan and also not for Hime-chan either. But they are doing it for entirely different reasons.
And I liked it too that this manga didn't make Akira a "trap".
This!
And Hime was always a 'tomboy' but it looks like both are entirely hetero... though Akira might be gay? Either way he is certainly thick-skulled to not notice Hime's feelings, geez!
Looks like a lot of 'over the top' fun!! And the teacher will probably sort it out in the long run.
Also: It's good that not everyone just falls all over themselves to accept it. Hime's 2 friends seem to have no issue with it, perhaps they'd seen it a few times before? But almost everyone else (including Akira's Dad) will at least be hesitant about it.
Girl meets boy, girl loses boy but gets a girl! Lolz!
