Translated from the Japanese.

In a postapocalyptic world, humanity has risen from the ashes of nuclear war, but only to a nightmare of endless suffering. It is a time of chaos. Gangs of savage marauders and warlords rule the broken ruins of civilization, terrorizing and enslaving the survivors. Life has become a brutal struggle for existence and death the only release. One day, a wanderer appears out of the wasteland to bring justice to the guilty and hope for the people - a warrior named Ken who bears seven scars upon his chest and holds the deadly secrets of a mysterious martial art known as Hokuto Shinken - the Divine Fist of the North Star!
