A worldwide nuclear war sometime in the 1990s has resulted in the destruction of most of civilization, turning the world into a desert wasteland. The remnants of mankind fight over whatever supply of food and uncontaminated water still remaining as the strong prey on the weak. Kenshiro is the successor to Hokuto Shinken, an ancient martial art of assassination that trains its practitioners to kill from within an opponent's body through the use of hidden meridian points. Kenshiro wishes to live his life in peace, but after he is separated from his fiancée Yuria by a jealous rival, he begins his journey to become the savior of the post-apocalyptic world, defending the weak and innocent from the many gangs and organizations that threaten their survival. Along the way, Kenshiro meets a young thief named Bat and an orphaned girl named Lin, who join him as his traveling companions and bear witnesses to Ken's many battles.
