Noboru Yoshikawa, a student of 3rd grade and 4th grade, has come in and out of Onizuka's room recently. Onizuka and Yoshikawa had become game friends. 　One day, Yoshikawa is called by a girl in the same class, Anko Uehara, and her friend, and is bullied to be naked and take a picture of her lower body. Onizuka, who helped Yoshikawa jump off the roof and try to commit suicide with regret and incompetence, takes Yoshikawa and makes a ridiculous revenge on Uehara and his friends.
