Set in the year 19XX, Kenshirou, a valiant warrior, roams a devastated post-apocalyptic landscape. His mission is to find his rival, Shin, who abducted his beloved fiancée, Yuria. Left for dead after a betrayal, Kenshirou uses his lethal martial art, Hokuto Shinken, to protect the weak against vicious marauders. His actions soon draw the attention of formidable foes, including warlords and other martial artists, plunging him into conflicts far beyond his initial quest.
As Kenshirou faces increasing challenges, the heir to Hokuto Shinken must test his abilities to their limits to recover what he values most. His struggles, especially against Shin and the warriors from the Nanto Seiken school, escalate his role to that of a hero in a cruel, radioactive environment.
