Eikichi Onizuka, former biker turned great teacher, is back home in the Tokyo suburbs for a well deserved break (...and to escape possible discipline from his employers at the Tokyo Kissho Academy). But once he arrives he quickly finds himself assisting a new child protection home as they try to guide troubled teens back to the path of happiness. Unfortunately for the GTO he has run into a buzzsaw in the form of Miki Katsuragi. Miki is determined to rid her home, the White Swan, of nosy know-nothing adults, and has the financial and political capital to not only have the teacher reconsider his lesson-plan but probably send off the straight and narrow entirely. Then again, who said Onizuka was ever on that path to begin with...The Oni-Baku rides again and manga will be all the better for it.

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.

And while Onizuka's curriculum may not rely on the reading, writing and arithmetic that is common in most classrooms, he has more than a few good lessons in personal development, fisticuffs and fun to teach a new generation of trouble teens.
