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.

　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?"

　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.

　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.

　Fujiyoshi, who has lost an important collection of money somewhere, is blamed by everyone in the class. Onizuka, who couldn't see it, said that he would work on the money, but he was impatient when he heard that the amount was 1.12 million yen. Apparently, the 1.12 million yen that Onizuka spent last night seems to be the money.

　Onizuka does everything in his power to get rid of the money he has spent, but it's totally useless. At that time, Fujiyoshi disappears.

　Onizuka heard from Kikuchi about the hidden treasure of a hidden Christian near Ishigaki Island. The market value is 2 billion yen!

　Onizuka, who is completely blinded, tries to hit a mountain by using a pair of students in 3rd grade and 4th class. However, on the way to the destination, the group of Yoshikawa and Kyoko goes missing.
