Sakamoto Toshiya (Kawahara Hideyuki), a young assistant head of the Yamashinkai, is imprisoned himself after his partner is killed in a feud with the Takahara family. When Sakamoto was released from prison eight years later and returned to the Yamashinkai, the organization was already under the control of the Takahara family and was involved in the sale of shabu, which was a taboo practice.

The Nishinaga clan tries to take Asamura's sister, Yuna, a singer, hostage, but Asamura retaliates against them and kills many members of the clan.

In order to fulfill the fate and great cause of placing his sworn brother, Kiyoharu Washio (Kazuyoshi Ozawa), who had been buried in the darkness until now, as the 12th generation leader of the Naito Shinjuku family, Yuki Kanemaru (Masaya Kato) covered the office with flames and ultimately met his end in self-immolation. Just as he passes away, former 12th generation underling, Hideyoshi Ogami (Norimasa Fujie), is released after serving a long prison sentence. This leads the Naito Shinjuku family into a three-way struggle: Toki Reiji (Yoshiyuki Yamaguchi) and his faction who support Taiga Washio (Haruto Ochiai) as the 13th generation, the faction led by Akira Shiba (Kunihiko Ida) who seeks to put Seiharu in power and rewrite history, and Ogami’s faction. Finally, the president of the Osaka Namba-kai, Masami Yukimura (Takashi Ukaji), reveals himself, and the story is about to connect to a new bloodline!
The Naito Shinjuku Family, a hereditary organization where only those of the Washio bloodline can inherit leadership.

In a shocking turn, Kanemaru engulfs the Naito Shinjuku Family in flames and meets his end through self-immolation. As Shateigashira Hosa (Yoshiyuki Yamaguchi) pushes to restore order by advocating for Taiga Washio (Haruto Ochiai) as the 13th leader, the situation spirals further out of control with the release of Shuyu Ohgami (Norimasa Tomie), a former Naito Shinjuku Family member, from prison...!
