The film’s story is a prequel to the Fist of the North Star depicting the one year interval between Kenshiro’s defeat at the hands of Shin and their later battle. Unlike the others in the series this film has a completely original storyline in which Kenshiro, near death after his battle with Shin and having used his remaining energy to kill a pack of wolves, was captured by slavers. Due to his strength, Kenshiro could escape whenever he wanted, but chose to stay and protect the other slaves.

A film adaptation of the Holy Emperor story arc, which primarily depicted the conflict between Kenshiro and Souther. New characters Reina, one of Raoh’s army officers who falls in love with him, and her brother Soga, Raoh’s advisor, play an important part with much of the plot involving Raoh’s relationship with Reina as he conquers the land; most of this portion is new content exclusive to this film. The other side of the story is the retelling of Ken’s attempt to save and protect the villagers from Souther’s army with the help of Shū. There is also a small subplot of Bart returning to his home.
