GTO: The Early Years - Shonan Junai Gumi(1990)

Shonan Junai Gumi!

Before Eikichi Onizuka would become the "greatest teacher in the world," he and Ryuji Danma were members of the infamous biker gang, Oni Baku. When they weren't out riding around and getting into trouble, this duo could be found in school. Doing what you ask? Picking up young women of course!
