Tough on the outside, all heart on the inside, Onizuka turned to the life of a high school teacher for less excitement and action . . .or so he thought. GTO, A.K.A.: Great Teacher Onizuka, is the racy story of Onizuka, a former motorcycle gang member who becomes a teacher to make a difference and... to meet girls? Using his street smarts to deal with colleagues, students and troublemakers, Onizuka finds that he too has many lessons to learn!
