Set sometime in the future. Five years have passed since the Shibuya riots. There are now several tribes that exist in Tokyo. Boys make up tribes, and they occupy areas under their influence. Kai Deguchi is a member of the tribe Musashino Saru led by Tera. One day, a member of Musashino Saru is killed by a rival tribe, Bukuro Wu-RONZ, led by Mera. Kai and Mera are former best friends, but not anymore. Meanwhile, Tera, the leader of Musashino Saru and a moderate who forbids using violence, is killed by Mera from Bukuro Wu-RONZ. Musashino Saru is now divided into two sides: one advocates following their slain leader's non-violence ideology, and the other side wants to use violence to exact revenge. A riot soon ensues among the tribes. ~~ Adapted from the manga series "Tokyo Tribe2" (トウキョウ トライブ トゥー) by Inoue Santa (井上三太).
