The sexually masochistic yakuza boss, Yashiro, isn't the type to warm up to others easily. But when Chikara Doumeki, his newly hired bodyguard, catches his interest, he reconsiders his "hands-off" policy with subordinates. As Yashiro's invitations fail, the yakuza boss finds out his bodyguard has a very personal reason for staying at arm's length.
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.
