After a major conflict, Kazuma Washio (Hitoshi Ozawa) becomes the 6th boss of Tendokai, Kanto’s largest yakuza group. Wakagashira Date (Hideo Nakano) and Kurata (Yoshiyuki Yamaguchi) secure casino rights from the government, but top officials are soon murdered, and Date is framed. The trail leads to Sanko-kai, a Kansai syndicate forming ties with a Korean underworld led by Myojin Akinari (Noboru Kaneko), brother of Washio’s old rival. Sanko-kai’s boss Onizuka (Hiroshi Fuse), who holds a grudge against Washio, launches a political and violent offensive. As Tendokai fights back to reclaim the casino rights, tragedy strikes—Okita (Yasukaze Motomiya) is targeted. Japan’s largest underworld war erupts again—what awaits at the end?
