Mito is an honor student at a school in Tokyo, and is a serious student with a strong sense of justice who serves as the manager of the track and field club. One day, Mito notices a delinquent student, Kami, mugging his classmate, Hosoda, and saves him. Hosoda has a crush on Mito, and takes this opportunity to confess his feelings to her, but she pushes him away, saying "I didn't mean it that way." Then, during the long weekend, the school is deserted, and a creampie gangbang training camp begins, where absurd rapes occur over and over again. #YoroP
