Togashigumi, who is planning to go to Gekokujo at the Kanto Ichienkai, was enthusiastic about the sima of the sand group. Deputy head of the sand group, Hitoshi Kamibayashi (Riki Takeuchi) and its chairman, Yoshiro Yazaki (Toshihiko Sakakibara) will raise the alert of the Togashigumi. In such a situation, Yoshiro is trapped by Togashigumi and is suspected of killing Togashigumi. Jin embarks on an attempt to uncover the truth instead of Yoshiro who dives underground. While Togashigumi's chairman, Kaido, declares war on the sand group, Hitoshi has to aim for Yoshiro as an organization's kejime.
