戸井玲野 花子

A ghost who died decades ago. Her current uniform is simply a reflection of what the girls at the school currently wear. Doesn't know how to ascend to heaven. Spends most of her time in the bathroom and is known across Japan as "Hanako of the Bathroom". Her real name has long ago been forgotten. Enjoys playing pranks but when her pranks get the new teacher in trouble she apologizes honestly.

Is obsessed with pee.
