List of Volumes

Great Teacher Onizuka (グレート・ティーチャー・オニヅカ Gurēto Tīchā Onizuka) is considered to be Tohru Fujisawa's magnum opus. Its publication began in May 1997 and ended in April 2002; concluding with the manga's twenty-fifth volume and its two-hundredth "lesson". All chapters were published in Weekly Shōnen Magazine.


"Finally, the plague that dwells within our, the plague within the modern Japanese society has surfaced------Teachers who only care about themselves instead of students' well being------Parents who leave their duty to their own child to teachers and schools------Children who lost their ways thanks to adults who abandoned them...this crumbling education system is the exact reason behind the plague-like corruption that has spread across all of Japan."

---Ryoko Sakurai, condemning the education system of Japan.

Onizuka is a reformed biker gang leader who has his sights set on an honorable new ambition: to become the world's greatest teacher... for the purpose of meeting sexy high school girls. Okay, so he's mostly reformed.

However, strict administrators and a class of ruthless delinquents stand between Onizuka and his goal and they will use any means, however illegal or low, to drive the new teacher away. Perfect, because Onizuka's methods won't be found in any teaching manual; he cares about the difference between legal and illegal activities about as much as he cares for the age difference between himself and a high school girl.

So get ready for math that doesn't add up, language you'd be slapped for using, and biology that would make a grown man blush... unless of course, you're the Great Teacher Onizuka.
