in a postapocalyptic wasteland ruled by savage gangs, a hero appears to bring justice to the guilty. This warrior named Ken holds the deadly secrets of a mysterious martial art known as Hokuto Shinken--the Divine Fist of the North Star!

In a postapocalyptic world, humanity has risen from the ashes of all-out nuclear war to a nightmare of endless suffering. It is a time of chaos. Warlords and gangs of savage marauders rule the broken ruins of civilization, terrorizing and enslaving the survivors. Life has become a brutal struggle for existence and death the only release.

Among the three Rasho, the generals who rule the land of the Asuras, only Hyo hangs on to a shred of his humanity. Deceived into believing that Kenshiro is responsible for the death of his sister, Hyo enters the demon realm to confront him. Meanwhile, Kenshiro searches for Hokuto Shinken's ultimate secret technique, one he will need when he squares off against the demon lord Kaio once again. What fuels Kaio's hatred, and what secret does he hold that could change Kenshiro's fate?
