Tokyo’s underworld is ruled by five legendary gangs, each led by a man aged 25–28 whose power comes from money, influence, and absolute loyalty. Though they control different territories, the leaders coexist peacefully, bound by respect rather than rivalry. Daichi Sawamura, Toru Oikawa, Tetsurō Kuroo, Wakatoshi Ushijima, and Kōtarō Bokuto stand as the undisputed heads of their own organizations, each running an empire built on influence and unimaginable wealth.
