Ordered to guard—and secretly kill—his underboss, a vengeful yakuza begins to fall for the very man he swore to destroy.

Three years after leaving the yakuza, Kataoka and Odajima enjoy a quiet life in Okinawa until a message threatens to pull them back in.

Kataoka and Odajima return to the yakuza world to save Kirii-gumi, only to discover a power struggle threatening its survival.

Kataoka is kidnapped by a dangerous gang, forcing Odajima to risk everything to find him and bring him home.

Captured by Boyd, Kataoka and Odajima risk their lives rather than abandon Kirii-gumi.
Trapped by Boyd, Kataoka and Odajima face a deadly confrontation as a new player arrives with a gun and hidden truths emerge.
