The peace that follows Raoh’s downfall does not last long and the world returns to turmoil several years later. Kenshiro rejoins his former travelling companions, Bat and Rin, in their battle against an oppressive Empire, fighting under the banner of the Hokuto Army. The Hokuto Army learns that the Empire has been taken over by an usurper named Jakoh, who has imprisoned the Celestial Empress and has been blackmailing her bodyguard, the Gento Kōken successor Falco, to do his evil bidding. The Hokuto Army fight their way into the central capital and free the Empress, who is in fact Rin’s long-lost twin sister Rui. With Rui now freed, Falco turns on Jakoh and kills him, foiling his ambitions.
However, Rin is taken captive by the remnant of Jakoh’s forces and is sent off to the mysterious Kingdom of Shura, a brutal land of warriors ruled by three overlords who have all mastered the ways of Hokuto Ryūken, a martial art which branched off from the same clan alongside Hokuto Shinken into the ways of darkness. Kenshiro defeats Han, the third-ranking overlord, who reveals that the Kingdom of Shura was Kenshiro’s birthplace. Moreover, Kenshiro also learns that Hyou, the second overlord, is his biological older brother, who lost his memories of Kenshiro after being separated as children and was corrupted into the ways of evil. Following a long gruelling battle, Hyou recovers his memories and reconciles with his long-lost brother. Kenshiro seeks out the highest-ranking and most powerful of the three overlords, Kaioh, who is in fact Raoh’s biological older brother. Kaioh plans a conquest to rule the post-apocalyptic world in the name of evil by wiping out the followers of Hokuto Shinken. With Hyou’s help, Kenshiro uncovers the sealed testament of the Hokuto Shinken founder, Shuken, which holds the secret to overcoming Kaioh’s ultimate technique.
Kenshiro emerges victorious over Kaioh and rescues Rin, leaving her under Bat’s care as he goes on an adventure with Raoh’s orphaned son Ryu. Meanwhile, a villain named Bolge appears, seeking revenge against Kenshiro for blinding him in a fight a long time ago. Bat brands himself with Kenshiro’s seven scars and fights in his place, only to be crucified by Bolge and tortured to near-death. Kenshiro rescues Bat, then fights and kills Bolge, while Rin regains her memories and professes her love to a recovering Bat. Afterwards, Kenshiro leaves and continues his role as the Post-Apocalyptic Savior, defending the weak and fighting off the greedy and violent, as the world finally begins to recover from the nuclear war.
