The Tennoji-gumi after the Haou War.
《Tennoji-gumi》 One of the largest yakuza organizations in the Kansai region. A chivalrous organization that engages in daily, bloody conflicts with the "hangure" (half-gray) gangs who encroach on their territory. Most members are "sane madmen." In the Haou War, they fought the Amou-gumi; after the Kido faction was annihilated and the former young head Ohtake—who started the conflict—took responsibility by ending his own life, the war concluded with the Tennoji-gumi's defeat. 〈Hierarchy〉 Sadaharu Mikuni: Chairman ↓ Kento Jinnai: Young Head (Wakagashira) ↓ Genya Togari ↓ Shigeyoshi Sendo ↓ Daichi Shibuya, Reiji Shiraishi ↓ Haruto Mabuchi ↓ Kazumi Shiina ↓ Masao Nitori ↓ Tako
