At that time, Sorimachi, who once fought off the rice paddies and the five-minute brothers' cup, is released after a long sentence. Sorimachi is stunned by the strange appearance of the group. He was furious at the rise of Hitoshi and Yoshiro, and began to draw a picture of the killing of the two and the takeover of the Sumida River Association.

Hitoshi Kamibayashi (Riki Takeuchi), acting leader of the sand group, is approached by Iwami and is ordered to push Iwami in the next presidential election. However, Iwami is demoted by the presidential election due to the strategy of Sunagawa, the parent of Hitoshi. The furious Iwami immediately awakened the Iwami group and declared a full-scale war to the Kanto Ichienkai.

Kanto Ichienkai, the largest Yakuza organization in the Kanto region. The conflict with the Iwami-gumi was won by the activities of Hitoshi Kamibayashi (Takeuchi), acting head of the sand-gumi, and Yoshiro Yazaki (Sakakibara), the chairman of the sand group, and the Ichienkai seemed to have regained peace. However, the lump of the Iwami-gumi war becomes a spectacular revenge drama and attacks the Ichienkai. It started with a proposal by Sakai, the new chairman of the Ichienkai, to return to the Ichienkai, which was split with the Iwami group. The Takayama group, whose leader was killed by the angry party, was furious at this proposal, and left the Ichienkai to collide with the angry party!
