Yashiro es un jefe yakuza con tendencias sexuales un tanto masoquistas, pero a pesar de todo, no se pone “caliente” fácilmente. Pero el nuevo guardaespaldas contratado, llamado Chikara Doumeki, capta su interés, y decide abandonar su política de “no intervención” con sus subordinados. Cuando todo lo que hace Yashiro para invitar a Chikara falla, el jefe yakuza descubre que su guardaespaldas tiene una razón muy personal para mantenerse a distancia.
The three brothers discover that the human experiment banned after destroying the "Orochi", is still going on to secretly revive the evil snake. They also find out that some ex-members of the Yamainu (the Japanese military unit formed to kill the snake) are behind this conspiracy. The brothers fight together again in a battle against the military.
