Before Eikichi Onizuka became a legend, before Onibaku, before he became GTO, he was just a normal junior high school delinquent. Getting into fights with his seniors, trying to pick up girls and just hanging out with his friends. Bad Company is a compilation of many short stories, linked together with the characters of Eikichi, Ryuji and their school buds. Such stories involve the origins of Eikichi`s bike, which we see frequently in GTO, the first meeting with the Midnight Angel and many other.

Great Teacher Onizuka is back, and the next stage for his legend is … prison?! The trouble magnet of a teacher reveals that this stint behind bars is thanks to a certain incident with the class he became assistant homeroom teacher of half a year earlier: Kissho Academy’s new class for high school-aged celebrities! Does he regret the exploits that landed him in the slammer? Heck, no. In fact, he’s all too happy to calmly tell his fellow prisoners how the whole thing went down—if they’re willing to listen to his story from the very beginning…

Fujisawa’s latest hit GTO: 14 Days in Shonan revives his most beloved franchise by introducing a new challenge for his unique anti-hero, Eikichi Onizuka. After accidentally compromising his school’s reputation, Eikichi (a.k.a. the GTO) goes home to the peaceful shores of Shonan to lay low until the heat dies down. However, Shonan itself hasn’t escaped its own share of troubles, and Eikichi is inspired to help a group of troubled foster children get back on the track to happiness. Using humor and a person touch to teach today’s youth, Great Teacher Onizuka continues to impart life lessons while rarely testing kids in the classroom.
