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.
