Kenshiro is the central figure in the narrative of the final confrontation with Raoh, serving as the 64th successor of the ancient martial art Hokuto Shinken. His background is defined by his training under the master Ryuken, alongside his adoptive brothers Raoh, Toki, and Jagi. Born in the Land of Shura, he was brought to Ryuken for training, where his naturally compassionate spirit distinguished him from his siblings, even as he honed his skills to become the rightful heir to the style.

In terms of personality, Kenshiro presents a composed and stoic exterior, but this masks a deeply kind and empathetic nature. He is moved by the suffering of the innocent and is known as a savior of the post-apocalyptic wasteland, protecting the weak from the tyrannical gangs and warlords who prey on them. While he shows great mercy to those who are not evil, he becomes ruthlessly efficient against unrepentant villains. His intolerance for injustice is absolute, yet he frequently expresses sorrow for noble adversaries he is forced to kill, demonstrating a profound respect for life even as he takes it. His motivations are driven by a desire to protect the defenseless, to reunite with his lost fiancée Yuria, and to uphold the benevolent principles of Hokuto Shinken against those who would use it for conquest.

Within the story of the fight against Raoh, Kenshiro’s role is to act as the primary challenger to Raoh’s rule as Ken-Oh, the Conqueror of the Century's End. Having already mastered the ultimate technique Musou Tensei, which allows the user to become one with nothingness and void any attack, Kenshiro is the only martial artist capable of stopping Raoh’s reign of terror. His journey leads him to the final battlefield at Hokuto Renkitouza, where he confronts Raoh to decide the true successor of Hokuto Shinken and to save Yuria, whom Raoh has taken captive.

The key relationship in this chapter is the conflict between Kenshiro and Raoh. While they are adoptive brothers, they represent opposing ideologies: Raoh believes in ruling through power and fear, while Kenshiro believes in protecting through love and compassion. However, their bond is complex; Kenshiro holds a deep respect for Raoh as the eldest brother, and their final battle is not one of hatred but of destiny. Raoh acknowledges Kenshiro’s strength and even admits that Kenshiro’s ability to carry the love of his friends, family, and Yuria in his heart is the source of his superior strength. Another critical relationship is with Yuria, the Last Nanto General and Kenshiro’s beloved. Her fate is central to the climax, as Raoh uses her to awaken his own version of Musou Tensei, turning her into the final catalyst for the brothers' duel.

Kenshiro’s development throughout this conflict reaches its peak in his mastery and execution of Hokuto Shinken’s ultimate techniques. He not only wields Musou Tensei but demonstrates a deeper understanding of its nature than Raoh, as his sorrow is tempered by love rather than consumed by ambition. His notable abilities include the use of Hokuto Shinken’s pressure point attacks to destroy opponents from within, famously declaring You are already dead to his foes. His signature moves include the Hokuto Hyakuretsu Ken, a rapid flurry of punches, and the Musou Tensei, which renders him intangible and invincible. In his final clash, Kenshiro proves that his power is derived from his emotional connections, allowing him to overcome Raoh’s equal skill and strength, ultimately delivering the decisive blow that ends the age of terror and brings light back to the world.
