Eikichi Onizuka is a 23-year-old ex-gang member. He is also the World's Greatest Teacher! As he began his quest to become the ultimate educator The young Onizuka discovers two principles of teaching - a social conscience and a sense of morality. So while he cannot use his strength on his kids his street smarts allow him to garner respect across the student body. As a homeroom teacher Onizuka focuses mainly on teaching life lessons, unfortunately his methods have created a stir among the PTA. To change the educational system as a whole, he embarks on a mission whereas he will individually mentor each student one-by-one, allowing each student to overcome their problems, whether they come from the classroom or from their home living rooms.
After a tiring and eventful school year Onizuka takes a break from the classroom and for his school break he decides escape the pressures of work by heading back home to the lazy surfers village of Shonan. Back in his hometown, he runs into friend of his significant other who runs an orphanage called the White Swan Youth Home. An orphan himself, Onizuka decides to help the home with hopes to help the kids in the same manner he does at school.
In the sixth volume of 14 Days in Shonan, Onizuka has to step out of the White Swan orphanage to attempt to change the entire culture of the Shonan youth scene. The White Swan appears to be heading in the right direction, however there is an outside source that is influencing the home in a negative way. This is a group of youths that is intent on waging war against adults. They feel that the adult world is what is wrong with their lives and they refuse to play by their rules.
Together these teens have created a group called the Oedipus Club. The Oedipus Club is an unusual gang that actively hunts down ignorant or weak-willed adults often blackmailing them or setting them up for insignificant assualt charges. Given that the "crimes" are alleged by youths the adult suspects are often treated as child abusers and occassionally sex offenders often damaging their lives forever.
The GTO must take on this gang and break them up before they destroy the White Swan. It is a race for their survival...keep the club going or save the White Swan from being burned to the ground!
