　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.

　Uehara's mother, the PTA chairman of Seirin Gakuen, boarded the school. Uehara, who was terrified by the revenge of the Yoshikawa bullying, told his mother, who is also an education critic. Onizuka, in a crisis of desperation, Yoshikawa, who is usually weak, makes a decision after worrying that "Is it because of me that Onizuka was in a pinch?"

　Kunio Murai, a student in the 3rd grade and 4th class, lives with his mother. Moreover, her mother "Juria" is a beautiful woman, and she is still in her twenties.

　One day, when Murai heard from the girls in the class that "I saw Onizuka and Murai's mother together," Murai became anxious about Juria's behavior when she went out in a fashion that she wouldn't normally do, and secretly. Follow me.

　Onizuka, Murai, Fujiyoshi, and Kusano who will be bowling at the setting of Juria. However, on the way, Juria, who was urgently needed, disappears and the game continues in a terrible mood.

　Meanwhile, Murai's mischief prevents Onizuka's fingers from coming out of the ball. Murai and his friends left the impatient Onizuka and left the bowling alley as they were, and on their way home, they were entangled by the Yankees and fell into a big pinch.

　"Fukuroda Hajime" is a physical education teacher who is proud of his physical strength. One day, Fukuroda, who was hazzled in front of the students because of Onizuka, challenges Onizuka, but no matter how desperate he is, he cannot beat Onizuka and is depressed.

　At that time, an incident occurred in which the bloomers of all the girls in the 3rd grade and 4th group were stolen. Fukuroda, who bets on honor recovery, enthusiastically sets out to find the criminal.
