Yasuda (Hitomi Matsuda), the Wakagashira of the Takemiya Union Tōjō-gumi, infiltrates the hideout of the Yamashina-gumi's Sakazaki (Junichi Kawamoto), who had been secretly engaged in organ trafficking. Yasuda tries to extract the truth from Sakazaki, but is killed by Detective Hyūga from the Organized Crime Division (Marubō). The blame is pinned on Yasuda, leading to his arrest. Two years later... In Yasuda's absence, the boss of the Tōjō-gumi, Tōjō (Hiroyuki Watanabe), is assassinated by a hitman from the Myōjin-kai. The situation changes drastically. Nikaidō (Tarō Kawano) pressures Yasuda to reestablish his oath of allegiance, but Yasuda firmly refuses. Frustrated by Yasuda's response, Nikaidō makes a certain proposal to the union's chairman, Shimamura (Shunsuke Kariya).

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?

To celebrate his 30th acting anniversary, Kōji Matoba stars as Seiji Oda, the fiercest member of Tendokai, who joins the organization under Kazuma Washio (Hitoshi Ozawa). In 2011, Tendokai dominates Kanto, while the rising Santōkai threatens them. Meanwhile, in Yokohama, Seiji Oda forms a rogue group, Oda Dōshi-kai, and violently protects his turf, clashing with Jinseikai. As Tendokai's Vice-Head Ryuji Kondo retires, Keiji Oda (Seiji's brother) is tasked with calming the tensions between the two groups, leading to a reunion between the Oda brothers.
