Released from prison in a general amnesty, Iwahashi returns to the bosom of the Enokiya gang. Here he finds that the feud between them and the Kannon gang has been resolved by a corrupt and successful enterpreneur, Asakura. But the Kannon gang have not forgotten that the reason that Iwahashi was imprisoned was for killing their boss nor forgiven it. And whilst Iwahashi has been behind bars, his boss has been assassinated. This leaves him as boss designate, a position he resigns to his closest friend, Sakaki.
