Joe Kazuma has defeated the towering Solomon, but victory comes at a cost. His triumph draws the wrath of the Gospels, a ruthless gang bent on retaliation.

With his mother’s safety hanging in the balance, Joe is approached by the Darumas—the rival mafia faction—with an offer he can’t refuse: protection in exchange for loyalty. Torn between his thirst for revenge and his moral compass, Joe agrees to join the Darumas, but secretly vows to dismantle the gang system from within.

As Joe descends deeper into the criminal underworld, his brother Zack continues his crusade against corruption in the police force. The brothers’ paths diverge further, each navigating a city where justice is compromised and power is everything.
