​In a mafia-governed city where corruption and violence is commonplace, two brothers find a mysterious artifact that will change their lives forever

Following the discovery of their father’s cap and gloves, the brothers Kazuma develop strange abilities. Joe, determined not to be walked over anymore, decides to make use of his newfound strength by returning to boxing.

Zack, on the other hand, will use his increased cognitive abilities to confront the corruption within his law enforcement hierarchy. Meanwhile, the Gospels encroach further into the territory of the Darumas, the local mafia. A gang war is declared!

By agreeing to replace injured friend Tony in a boxing match against Solomon, Joe was not aware of the situation he was getting into. He now represents the mafia gang Darumas, and as powerful figures will have their eyes on the fight, defeat is not an option.

Will the young challenger have shoulders strong enough to face the champion of the Gospels alone?
