The Oni-Baku meet Ayumi and Mariko at Yoron Shima in volume 1; Eikichi sees it as a chance to ‘get lucky’ and is constantly trying to grope Mariko.     With the revelation that the two women are not students as they claim, but are actually teachers at their new school, Eikichi initially seeks revenge on Mariko but eventually they get along. When Ayumi leaves, Mariko remains an occasional member of the SJG cast and mainly helps the pair out of difficult situations. She is also the daughter of a Yakuza boss, and a former member of Kadena Nao's 'Purple Haze' gang.

Eikichi Onizuka and Ryuji Danma are members of infamous biker duo, the Oni Baku. When not out riding around, they can be found in school, trying to pick up young women. This is the story of the young Onizuka, who would later become the greatest teacher in Japan, and his partner Ryuji in their quest to lose their virginity and reach maturity. 
They are widely feared bosozoku, and are known for their tenacity and viciousness in a fight. However, this lifestyle does not exactly endear them to the opposite gender, so they decide to change their ways. However, this is easier said than done.
