In this fourth film in the series, Itto Ogami is hired by the Owari clan to eliminate a tattooed assassin, who is killing her enemies and cutting off their topknots. But the job isn't as easy as it sounds, as Ogami learns more about the woman’s past and her motives to walk the path of vengeance.
Meanwhile, Daigoro is separated from his father when he follows a pair of traveling street performers outside of town. Gunbei Yagyu, who was humiliated by Itto Ogami in a duel before the Shogun when competing for the position of head executioner, crosses path with the now solo Daigoro and follows him.
In this film, Ogami will have to face an army of samurai from the Yagyu family, before facing Retsudo Yagyu himself.
