CONFLICT GAIDEN II: Oda Seiji.

At Sagamikai's headquarters, Kawashige (Daijirō Harada) is confronted by Iwamura, the chief of Yokohama Port Police, who demands the dissolution of Sagamikai. Suspecting a traitor within, Kawashige orders his men to investigate. The suspect is Keisaku Sugita (Daisuke Iijima), a veteran of Sagamikai and father of Shinsaku Sugita (Gento Aoki) from Oda Dōshi-kai. When Sagamikai attempts to take Keisaku, Shinsaku intervenes, injuring their men and helping Keisaku escape. Seiji Oda (Kōji Matoba) is summoned by Kawashige, who demands the return of Keisaku, but Oda firmly refuses. War between Sagamikai and Oda Dōshi-kai is imminent.
