Nuclear war has devastated the planet, turning once fertile ground into a barren, inhospitable landscape in which humanity struggles to survive. Society has collapsed, and battles for control erupt among vicious dictators, super‑powerful mutants, and biker gangs that terrorize the streets. In this cruel, bleak world, only a chosen one can restore civilization to its former glory. Kenshiro, the master of the Hokuto‑Shinken fighting technique, wields a martial art so brutally effective that only a single being can be entrusted with its full power.
