A self-destructive man becomes a powerful member of the yakuza but quickly loses his self-control. Based on the true story of Rikio Ishikawa.

After a heist, four criminals lay low in a remote safehouse, waiting for orders. As paranoia builds, one thing becomes clear — the real threat may not be outside, but among them.

A westerner named Casey, studying Ninjutsu in Japan, is asked by the Sensei to return to New York to protect the legendary Yoroi Bitsu, an armored chest that contains the weapons of the last Koga Ninja.

In an alternate Japan, territorial street gangs form opposing factions collectively known as the Tokyo Tribes. Merra, leader of the Wu-Ronz tribe of Bukuro, joins forces with heavy-hitting gangster Buppa of Buppa Town. With Buppa's support, Merra aims to initiate a gang war between the Wu-Ronz and the Musashino Saru, and in a confrontation between the two attempts to kill Kai of the Musashino Saru. The inadvertent murder of Kai's friend Tera (a Musashino Saru member beloved by all Tribes since before their formation) leads to the joining of forces between all of the Tribes in an all-out war against Merra and Buppa.
