The class "jock bully", Kunio Murai is not very bright and loses his temper easily. When Eikichi Onizuka arrives at the Holy Forest Academy, Kunio and his gang (consisting of Kouji Fujiyoshi and Tadaaki Kusano) attempt to kill him several times with seemingly innocent pranks, such as a cockroach planted in his school lunch. The plans backfire (such as Kunio eating the cockroach, instead) and he goes insane, nearly ending up with his face impaled on a pair of razor-sharp scissors. Onizuka then takes advantage of Kunio's 27 year-old mother, Julia Murai, after trouncing Kunio at several arcade games. It is later revealed that Julia was carrying her son at the age of 13, and her parents and boyfriend abandoned her, making Kunio overprotective of his mother.

Kunio and his gang befriend Onizuka, after he saves them from a group of ruffians, but not before Onizuka joins the ruffians and has Kunio bungee jump off the Tokyo Bay Bridge. Kunio still gets very angry when Onizuka tries to make a pass at his mother, especially with the possibility that Onizuka may well be his new stepfather. His fear of a new father also rears its head when he suspects his mother may be marrying a man who resembles Dr. Elefun from Astro Boy.

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.

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.
