Once the largest Kanto yakuza organization in Japan, Tendokai, led by 6th-generation boss Kazuma Washio (Hitoshi Ozawa), now faces the rapid expansion of Jinseikai, which has begun to dominate Kanto. In an attempt to revive, Okita (Yasukaze Motomiya) and Kurata (Yoshiyuki Yamaguchi) re-establish the Washio-gumi and raise the banner of rebellion, attempting to make contact with the Korean mafia.

They are warned by retired Kozo Otani (Shun Suda) about an impending police raid on their organization. Despite Kurata's questioning, Otani remains vague. Meanwhile, Akinari Myojin (Kaneko Sho) discovers that Jinseikai was being controlled by Prime Minister Anan (Ikki Hankai). Before they can act, Jinseikai's headquarters is destroyed by a "mysterious man." Hozumi (IZAM) of the police suspects Washio-gumi is behind it, but Okita and Kurata are uncertain.

Former Tendokai Sixth-Generation Chairman Kazuma Washio (Hitoshi Ozawa) waited for a man in a VIP room at a high-end bar. The man was Sasahara Goro (Tetsu Watanabe), a former police officer who secretly orchestrated the conflict between Tendokai and the Tōnin Rengō. Now, Sasahara was the Tokyo Metropolitan Police Commissioner. Washio demanded Sasahara arrange a meeting with Prime Minister Kenzō Anan (Ikki Hankai). Meanwhile, at Washio-gumi, the Sankōkai—the group that led to the disbandment of Tendokai—arrived. The current leader, Daiki Yabuta (Kenji Matsuda), was once a close ally of Okita. Yabuta proposed an alliance with Washio-gumi and asked Okita to join forces. What is Yabuta's true intention, and what will Okita decide?

The Nihon Tōgōsha continues to dismantle yakuza organizations across the country. To survive, Sankōkai Fourth-Generation Chairman Daiki Yabuta (Kenji Matsuda) plans to create a new yakuza group led by Okita Shōhei (Yasukaze Motomiyac) from Washio-gumi. This group aims to unify yakuza nationwide, similar to the former Tendokai under Kazuma Washio (Hitoshi Ozawa). Meanwhile, within Nihon Tōgōsha, Kazuma Washio is expanding his influence, prompting the leader Tōjō (Kentarō Shimazu) to take action and plot Washio’s assassination. However, the plan leads to unexpected outcomes... Additionally, a letter sent to Washio-gumi and other national yakuza organizations pushes Okita and the others into even greater peril.
