No, once I think about it properly, it's Chie. But she's not a student aaand on second though she is a lesbian paedophile so disregard that.
Anyways, Nami isn't too normal, even though it's kind of her puchline and all. I'd say she has some serious self-esteem problems.
And that leaves us with Fujoushi. She's completely normal, except the yaoi stuff and even somewhat talented in both sports and drawing.
