Last Bronx ~Tokyo Bangaichi~ (1996)

The leader of Soul Crew, the toughest gang in Tokyo, was viciously killed. Shortly after that an anonymous challenge appeared in graffiti scrawls all over the city "inviting" all of the city's gang leaders to a fighting tournament that will settle which group has the power to rule Tokyo. Everyone knew refusing to participate was not an option.
