The Oriki-gumi’s quest for Owari unification is fractured by a bloody succession feud between Nobunaga (Hitoshi Ozawa) and his younger brother Nobuyuki (Masaki Nishimori). Nobuyuki’s reckless schemes invite full-scale invasion from Yoshimoto Imanishi’s Suruga forces, with Ieyasu Tokusawa (Yasukaze Motomiya) spearheading their advance into eastern Owari. The crisis drives boss Nobuhide Oriki (Tokuma Nishioka) into a fatal illness, leaving the family leaderless. The Oriki-gumi now faces not only an external war but also internal strife over succession. Across Owari, tensions flare. Nobunaga’s blood relative, Nobuyasu Iwasaki (HitomiMatsuda) of the Iwasaki-gumi, makes his move. Michizo Saimon (Shinzo Hotta) pushes his Saimon-gumi from neighboring Mino. And lurking in the shadows, the Tokyo Metropolitan Police plot the downfall of the yakuza world itself. Thus, the underworld descends deeper into its own warring-states era.
