Hmm the one to the upper right doesn't look like a girl does it?

Doesn't really look all that feminine that's for sure.

But she must be a girl or else the tsundere's anti-guydar would be picking up and have kicked him out.

She's sporting twintails so she must be a tsundere! *gasp* And even thighhigh socks!!
