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.

Kenshiro takes on the Holy Emperor Souther, the most powerful of the Six Holy Fists of the South Star. Once Kenshiro defeats him, it will set up a fateful battle between Raoh and Toki, a confrontation between motion and stillness, ferocity and serenity-a battle in which neither master will yield an inch. And overhead, Shichosei, the star that presages death to all who have seen it, Toki included, shines in the darkening sky.

Kenshiro has at last found Yuria, the woman he loved but had given up for dead. Determined to possess her as well, Raoh has also reached Yuria's stronghold. Kenshiro and Raoh's paths were always destined to lead them to this confrontation, the final battle to decide the successor to Hokuto Shinken. In this fight, both men will unleash the greatest secret technique passed down to them by their master, but only one will survive using it!

After an epic contest, Kenoh leaves his brothers to begin a new reign of terror in the wasteland. But while he was away, Ryuga, one of his lieutenants, turned against him and established his own stronghold. Ken and Toki head there to find out what Ryuga knows about Kenoh. Meanwhile, the one force that may still stand against Kenoh is the Goshasei, the Guardian Stars of Nanto, and their last general, whose secret will bring Kenshiro face-to-face with those he thought he'd lost...

Years after the fall of Raoh, Kenshiro has disappeared, and Rin and Bat have grown to young adulthood. Attempting to honor Ken's legacy, they wander the wasteland defending the defenseless. Kenshiro himself now seeks only peace, hiding himself away in an isolated settlement. Tormented by the memories of those he has lost, he tries to give up the way of the fist. But the forces of chaos are always on the horizon, and Kenshiro will have to once again embrace his fate as the successor of Hokuto Shinken

As the years have passed, peace has come to the wasteland. But it is an unjust peace, one kept in place by the brutality of a powerful empire. Rin and Bat, having finally reunited with Kenshiro, are now freedom fighters. Along with a bounty hunter named Ein, the group faces new enemies-Falco the Golden Wolf and the cruel warlord Jako, who serve the mysterious Tentei. Falco and Jako may have whole armies at their beck and call, but they've never come up against the likes of Kenshiro and Hokuto Shinken before
