The Murder Corps: Road to Kansai Domination (2001)

After their desperate battle against a hundred men, the six members of the Tokuyama-kai complete their prison sentences and are released from the Osaka Detention Center. Meanwhile, back in Nishinari, Koyukai and Nakane-gumi have been fighting for dominance, and the Tokuyama-kai’s territory has been completely taken over. As the Tokuyama-kai attempts to reclaim its turf, the powerful Mizuta-gumi and Jinra-gumi, backing Nakane-gumi and Koyukai from behind the scenes, move to wipe out the Tokuyama-kai entirely.
Facing threats from Osaka’s strongest Mizuta-gumi and Kobe’s largest Jinra-gumi, Katsuhiro Tokuyama realizes the gang’s survival is at stake. He makes a decisive choice—to take on the yakuza crest.
The Tokuyama-kai becomes a subordinate organization of the Jinra-gumi. Then, Jinra-gumi boss Chujiro Jinra (Sonny Chiba) issues his command: as the first step toward nationwide unification, the Tokuyama-kai is ordered to conquer Wakayama.
