Fuko Onozuka

Fuko Onozuka is a character first introduced in a one-shot, who later got involved with the main storyline. She's a freshman at Oto High School and is infamous for her horribly bad luck.

Appearance
Fuko seems to be on the shorter side of average height. She has almost shoulder-length hair which she tends to pin down in the front to keep it out of her face.

She wears the regular Oto High School uniform, with little variation every now and then; sometimes she wears it with a blazer, sometimes with a cardigan, and sometimes she is depicted with just the dress shirt. During her free time, she has been shown to wear an oversized hoodie with a pair of yoga pants and regular sneakers.

Personality
Fuko is very respectful and kind, as well as somewhat quiet. She gives off the first impression of someone rahter reserved, however, around people she is on friendly terms with, she seems to show a sillier side of herself. In these instances, she is not trying to be funny. She just appears to be a bit slow and overly optimistic, to the point that even Kako, the human equivalent of dumb optimism, is confused by her attitude.

Background
Not much is known of her background, and her bad luck has never really been explained. She seems to have been horribly unlucky for most of her life, evidenced by how seamlessly she is able to deal with it. As an example, she carries tissues with her just in case a bird poops on her.

Jiro Nagakura
Fuko had a crush on Jiro for a long time before they got together. During the Yui-arc they've been shown to be a super lovey-dovey couple.

Mikado Yaguchi
Even though Mikado and Fuko were initially rivals in love, neither of them dislikes the other, as a matter of fact, they seem to be on quite friendly terms with each other.

Kako Motoya
While initially making the decision to be on Mikado's side in the love triangle, Kako can't help but like Fuko and her kindhearted nature.
