Monnojo Monda, a lone-wolf delinquent, rises in the world of biker gangs and yakuza with his manliness and fighting skills.

Junji, an outcast from Nishimachi High, and Junichi, an outcast from Kitamachi High, both end up being expelled and transferred to Kaseiin High School, a school where "losing" is absolutely unacceptable!?

The setting is different from the Kodansha version and is not directly a sequel.

The time is set in the Mechatronics Era in the future. In this era, schools actually float in the Tokyo sky at around 2000–3000 meters. At home, there is freedom in movement as everyone has a flight mechanism within them which allows them to fly. Transportation is made easy as a result. Source: ANN
