The Sakyo-kai is a legendary yakuza syndicate. Set in the Heisei era, at the absolute peak of the Sakyo-kai's power—undefeated and unafraid of death. Saki, the next-in-line boss; Shokaku, the candidate for lieutenant known as the 'Demon' of the Sakyo-kai; Kyohei, Shokaku's rival known as the 'Tiger'; and Rin, the cunning swindler. Guest is a highly capable member serving as the secretary to the current Chairman, a vital figure who manages the organization and keeps it running, second only to the Chairman himself.
