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.

　Toroko's office is in debt and is on the verge of bankruptcy. Onizuka, who wants to help Toroko, gets into the office, but on the contrary, he becomes chased by the creditor yakuza. Inevitably, Onizuka tries to get the help of his friend "Toshiyuki Saejima", but Saejima's attitude is strange. In fact, Saejima was trying to escape by stealing a lot of gold bars that he had kept secret from his boss.

　Last year's 2nd year and 4th group teacher "Noboru Saito" stabbed his chest and was hospitalized. Saito is the person who created the cause of the current 3rd grade and 4th class teacher bullying.

　At the same time as the incident, Ya stopped coming to school. Kikuchi and Murai are suspicious that "Maybe Masa stabbed Saito?"

　Without any solid evidence, the battle between Onizuka, the students of the 3rd grade and 4th grade, and the teachers of Seirin Gakuen began against the domineering board of education who decided that the criminal of the Saito teacher stab injury case was elegant. ..

　Onizuka, who bets his life as a teacher and pursues the board of education with a flashy performance, makes a ridiculous remark about the incident this time.
