Eikichi Onizuka begins his career as a teacher-in-training expecting that he will get a class of attractive, nubile high school girls. When he is assigned the problem "Class O", a group of delinquents and blackmailers, only his tough love is able to win them over.

On the day of the teacher employment exam, Onizuka, who failed to take the exam due to a misunderstanding, feels like a dong. At that time, my best friend "Danmari Ryuji" will be interviewed by the prestigious "Seiringakuen", a private school where you can become a teacher even if you fail the teacher employment exam. Is recommended.

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.

A metamorphosis photo of Onizuka was posted all over the school. Onizuka, which I don't remember at all, is crazy. When I saw it, I was beaten in Fuyutsuki, and I was just stepping on and kicking. Anxious, Onizuka wonders, "If I'm a multiple personality, I might be doing such a ridiculous act without realizing it!" However, it was actually a homeroom bullying strategy organized by 3rd grade and 4th class students.

　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.

　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.

　"Tomoko Nomura" is a dropout of 4 groups in 3rd grade. Toro is always failing no matter what he does, and his nickname is "Toroko". It was Miyabi Aizawa, a classmate from elementary school, that Toroko had longed for. However, Ya who failed due to Toroko in the Onizuka fall operation during this time is furious. Make Toroko out of the group. Onizuka was worried about Toroko ...

　Toroko will participate in the audition as told by Onizuka, but she still fails because she is a nerd. Ya, who participated in the same audition with such Toroko as a slapstick, goes through the selection steadily without connecting. Toroko becomes sad. Then, Onizuka says to Toroko, who is trying to escape from the final selection acting section, "Why don't you talk to him again in a way that only you can do?"

　Mathematics teacher Yu Teshigawara is an elite teacher who has distorted feelings in Fuyutsuki. Therefore, I don't like Onizuka, who is close to Fuyutsuki. 　Teshigawara, who wants to get rid of Onizuka from the school, decides to use the help of Mrs. Ota, an influential person in the women's group.

　Mrs. Ota boarded the school to inspect the Onizuka class. However, Onizuka appears in the crotch as an elephant cosplay, and perhaps the water from the water gun that comes out of his nose is poured on Mrs. Ota. Onizuka is in danger of unemployment again due to a scandal, but the disposition is put on hold for the time being, and as a condition for remaining, he will have to take the first place in the nation in the common academic ability test of junior high school, which is scheduled for a week later.

　If you don't get the first place in the national mock exam, you will get fired. Fuyutsuki, thinking that he wouldn't let Onizuka get fired, invites Onizuka to his apartment and tries to hold a study session. Onizuka had a delusion that didn't meet Fuyutsuki's offer, but for a short while, a hellish week began.

　On the day of the nationwide mock exam, Onizuka, who accidentally witnessed the kidnapping of Mrs. Ota's daughter Hidemi, heads for rescue after the exam. The purpose of the kidnappers was to take a behind-the-scenes video of Hidemi to put pressure on the public works projects of her father, a member of parliament. 　At that time, Fuyutsuki and Murai were screaming at Onizuka, who never appeared at school.

　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.

One day, there was a love letter with "F" and initials in Murai's shoe box. Actually, it was a girl "Kujirakawa" in 3rd grade and 2nd class who was asked by a friend to give it to Murai. However, the initials of the Whale River are also Fuyumi and "F". I suspect that Kusano and Fujikichi are actually from Kuregawa himself, but in reality it was from Fuyumi's friend Akane Fujita.

　Fuyutsuki, a young and beautiful girl, is a popular boy student. However, probably because of that, the girls were strongly opposed to it. One day, a girl in the class finally boycotts the class. Fuyutsuki, who lost himself, escapes from school and disappears on the way. Onizuka, who was worried when he heard that, took Kikuchi, Murai, and Toroko, who happened to be there, to Hakuba, a place of memories of Fuyutsuki.

Fuyutsuki and the old elementary school building, which is the place of memories of the pension daughter "Kizaki Hitomi", will be blown up for shooting. His eyes were deeply hurt because he thought he was betrayed by a teacher he trusted, but he finally opened his heart by persuading Onizuka. Before the school building was blown up, his eyes got into the school building where the explosives were set to carry out the organ, which is a memorable item.

　"Letter of misfortune" becomes popular at Seirin Gakuen. A mountain of misfortune letters arrive at Onizuka, but Onizuka, who does not believe in the curse of curse at all, burns it all. However, from that day, ominous things began to occur around him, and finally Onizuka fell into poor physical condition.

　Hiroshi Uchiyamada, 51 years old. Vice-principal of the prestigious Seirin Gakuen. He works as a middle manager and is stressful. The only place where I could feel at ease was Iruma's home ... but recently Onizuka has come in and out of that home as a tutor for my daughter Yoshiko. 　One day, Dr. Sannomaru brought a picture of an enkou dating site in Onizuka in a hotel district in Shibuya. However, that person is ...?!

　"Kadena Nanao", a teacher in the infirmary with a lot of sex appeal, has been assigned to Seirin Gakuen. Immediately, the south wind, which caught the hearts of not only boys but also girls, began selling suspicious products to students and teachers in the health room.
