Ryouko Morigawa

A beautiful girl who usually fights with a shinai. When she is introduced into the story, she notices her cousin Satoru's bruises from Hokunei. Satoru lies and tells her that it was Mitsuhashi who did it, in order to keep her out of it. However, that only makes things worse and she tries going after Mitsuhashi and the others. Later on, she develops a crush on Imai due to his good nature. She was herself a (unwilling) delinquent and decided to change herself to a normal girl when she transferred, although it didn't last very long and she soon became respected by the other delinquents of her new school.
