OVA
Description
Kenshirou is the 64th successor of Hokuto Shinken, an ancient assassination art targeting hidden meridian points to inflict fatal internal damage. Seven distinctive scars form the Big Dipper constellation on his chest, inflicted by Shin during a defeat where Kenshirou was left for dead and his fiancée Yuria kidnapped. This event transformed him from a forgiving fighter into a merciless warrior driven by vengeance.

Born in the war-torn Land of Shura, Kenshirou was rescued as an infant alongside adoptive brothers Raoh and Toki during conflict and raised in Japan by Ryuken, the previous Hokuto Shinken master. Ryuken trained Kenshirou and his brothers—Raoh, Toki, and Jagi—ultimately choosing Kenshirou as his rightful successor. This decision fueled jealousy, particularly in Jagi, who later manipulated Shin into challenging Kenshirou.

Following the nuclear apocalypse of 199X, Kenshirou sought peace with Yuria but was forced into nomadic life after Shin's attack. Journeying across the post-apocalyptic wasteland, he protected the innocent from gangs and warlords, earning the title "Savior of the Century's End," accompanied by orphans Bat and Lin. He confronted his adoptive brothers: Jagi, who committed atrocities in his name; Toki, who chose healing despite radiation sickness; and Raoh, who declared himself Ken-Oh and sought to conquer the wasteland.

Their conflict culminated in a final battle at the Hokuto Renkitōza, where Raoh sought to unlock the ultimate technique, Musou Tensei, by killing Yuria. Kenshirou emerged victorious through a deeper understanding of life and death, sparing the terminally ill Yuria thanks to Raoh's intervention. After Raoh's death, Kenshirou lived peacefully with Yuria until her eventual passing.

Later, Kenshirou allied with the adult Bat and Lin, now leading the Hokuto Army against the oppressive Celestial Empire and its usurper, Jakoh. This journey took him to the Land of Shura, his birthplace, where he confronted blood relatives: his elder brother Hyoh and Kaioh, Raoh's blood brother. He defeated Kaioh, uncovering the founder's testament to overcome his dark techniques. Kenshirou later took Raoh's orphaned son, Ryu, as his protégé to train as the 65th Hokuto Shinken successor.

A prequel story set after his defeat by Shin depicts Kenshirou's physical and emotional recovery, where he grappled with despair before accepting his role as the wasteland's savior. He confronted remnants of Shin's forces, solidifying his resolve to protect the innocent.

Throughout his life, Kenshirou balanced extreme violence with profound compassion. He openly grieved for fallen noble adversaries and lamented innocent suffering. His famous catchphrase, "You are already dead," underscored his inevitability as a warrior. Despite his ruthlessness, he acted selflessly, deviating from his path to confront threats to the vulnerable, driven by an unwavering hatred of injustice.
