Joe Kazuma's loyalty to the Darumas is put to the ultimate test. After agreeing to join the mafia clan to protect his mother, Joe is kidnapped by the rival Gospels--who are still reeling from his defeat of their champion, Solomon.

Their leader, Marco, offers Joe a deal: spy on the Darumas or face the consequences. But Joe refuses to betray his new allies, even as the danger escalates.

Saved by Seiko, Brad, and Ben, Joe is thrust into a violent clash between the city's most powerful gangs. As the battle rages, Marco corners Seiko, forcing Joe to make a choice: reveal the supernatural powers he's kept hidden, or risk losing everything.
