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.

　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.
