Kaptain Kamikaze is a girl who finds herself transferring from school to school because she's a bit of a juvenile delinquent. Now she finds herself in an almost all-boys school named Danmura Academy. The ratio of boys to girls is 9:1, which means the main character is around a lot of boys. Somehow Ouka, the main character, must find a way to overcome the male juvenile delinquents and save the other schoolgirls. Ouka is a strong girl, but there are a lot of boys who would rather not see a girl or a bunch of them takeover their academy.
