In the new semester, Onizuka was able to become a teacher at Seirin Gakuen on a sunny day, but the first class he was in charge of was not the high school he admired, but the middle school. Onizuka is disappointed to hear that he is a homeroom teacher for junior high school students, but rumor has it that the class that Onizuka is in charge of, the 4th class in the third grade of junior high school, was a problem class in which there were three homeroom teachers who had quit school due to mental stress.

　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.

　A beautiful woman named "Urumi Kanzaki" appeared in front of Onizuka who lamented that she wanted a lover. The two stop by a laundromat to dry their soaked clothes, but Onizuka gets caught up in her tricks and is suspected of being molested.

　The next day, Reimi appears again in front of Onizuka, who teaches with a moody face. Reimi hasn't attended school yet, but she is a student of 3rd grade and 4th class, and has been a genius child since the beginning of the school, which boasts an IQ of 200 or more.

　Onizuka desperately tries to open her heart when she learns of Reimi's loneliness with her eyes closed. However, Reimi confuses Onizuka by deliberately entwining her with a yakuza, perhaps because she can't believe her heart.

　When Reimi finally thought she was about to open her heart, Onizuka accidentally pushed her off the roof of the building with a donketsu!

　Reimi was safe without any injuries, but Onizuka, who had the weakness of killing her, had no choice but to follow Reimi. Onizuka goes to a sushi restaurant to make Reimi eat Toro, but the actions taken by the poor Onizuka escape. On the way, Onizuka collided with a car, but the opponent who collided happened to be the wagon of Toroko's office.

　Reimi was pleased to see her again, but as soon as she saw her elementary school teacher, Fujimori, who she was supposed to meet as an interviewee, Reimi's expression froze.

　Seirin Gakuen panics due to Reimi's radical class terrorism. Onizuka goes to Fujimori's house to see what happened between Reimi and Fujimori. After hearing from Fujinomori, Onizuka takes Reimi out of the school with the cooperation of Ryuji and her old friends, and gives a ridiculous extracurricular lesson.

　Toroko, who became an entertainer, will appear in a trendy drama. Although he plays the role of Choi, Toroko is full of motivation. However, the selfishness of the scriptwriter cuts off her turn. Onizuka, thinking of Toroko who is sad, takes in the scriptwriter and asks Toroko to increase her turn. In addition, he will take charge of the management of Toroko in place of the merciless manager "Ichiro Okinoshima".

　Toroko will appear in the "Shonen Magazine Gravure Princess Contest", but her rivals are all strong opponents, and Onizuka's efforts are empty, and the number of postcard votes continues to be the lowest. On the contrary, the address of Toroko's home was published in the magazine as the address of the fan letter, and the swimsuit for shooting was gone, and disasters occurred one after another.
