The street fighters of Oya High and the delinquent brawlers of Housen Academy face off against each other when both seemingly attack each other.

Chiku is a devastated and dangerous town with 5 gangs fighting fiercely. Mugen and the Amamiya Brothers clashed, leading to Mugen disbanding.

Members of SWORD win against Wangan Rengogun, which is led by Kohaku. The city becomes peaceful again. Nevertheless, the most brutal gangs, Doubt and Prison Gang, appear. They try to dominate the area controlled by SWORD.

Fists fly when Oya High’s street fighters defend themselves from a three-school alliance of brawlers.
