In order to earn legal Shinogi, Sunagawa was trying to start a unified legal business with a one-yen coin with the support of members of the Diet. However, the skirmish between Shimizu-gumi and Masago-kai, the main organization of the Ichienkai, intensified, and the plan began to be hindered. Jin, who has a good face in the two groups, enters arbitration, but the conflict continues to intensify as the leader of the Shimizu group is shot by the Masagokai and the Hitman of the Shimizu group. Yoshiro, who was investigating both the Masagokai and Shimizu-gumi, notices that there is a strategy of Mizuho-gumi, the director of the Ichienkai, in the shadow.
