Meet Eikichi Onizuka, a 22-year-old ex-biker. He's crude, foul-mouthed, and has a split-second temper. His unlikely goal: to be the Greatest High School Teacher in the World! Of course, the only reason he wants to be a teacher is so he can try to score with the hot students… Before he can become a full instructor, he's got to work as a student teacher to earn his credentials. Onizuka may think he's the toughest guy on campus, but when he meets his class full of bullies, blackmailers, and scheming sadists, he'll have to prove it. Won the 22nd Kodansha Manga Award for Shonen
