Fumiko Onosaka (小野坂 史子,Onosaka Fumiko?) is a minor character that appears in Blood School.
Fumiko has around shoulder-length hair pulled into two low pigtails. She wears a white, short-sleeved blouse and a mid-thigh length pleated skirt. She wears a thin ribbon around her neck as part of her uniform.
Fumiko is surprisingly peppy considered her circumstances and doesn't seem to mind being dead. Like the other spirits that linger in the old schoolhouse, she has a degree of spiritual power granted to her. Whilst she speaks in a jokey and light-hearted manner, she can put it aside to be serious when it comes to more troubling matters.
Tatsuya refers to Fumiko repeatedly as 'Hanako' as he believes she is the spirit Hanako of the toilet (トイレのはなこさん,Toire no Hanako-san?).
Due to her blue-tinted color as a spirit, her original eye and hair color can't be determined.
One set of her portraits and a CG depicts her holding a handheld console that looks incredibly similar to the Sony PlayStationPortable.
