Liu Kaioh oversees Bailin Temple in Heilongjiang, China, training disciples like Kaiou Retsu in Chinese Kenpo. Despite nearing a century in age, he sports a muscular frame, bald scalp, and a white beard framing crossed eyes. His attire—sleeveless white shirt, black kung fu pants, and cloth-bound shoes—reflects austere practicality. A rigid traditionalist, Liu Kaioh prizes martial excellence above all, once withholding Retsu’s Kaiou title for failing to replicate Kaiou Dorian’s mythic feat of carving a mountain tunnel barehanded overnight. Only Dorian’s intercession swayed him to grant Retsu the rank, though he upheld unyielding standards for future successors. At the Raitai Tournament, Liu Kaioh challenges Yujiro Hanma to a stone-shattering duel. When Yujiro tears away half his face mid-battle, Liu Kaioh persists despite grievous injury, flinging a bloodied towel to blind his foe before striking back. His mastery of pain tolerance and Byaku-Rinji-style Kung Fu—capable of pulverizing stone water tanks and smashing reinforced doors—keeps him alive, though his post-battle recovery leaves his visage uncertain. He espouses martial arts as a path to self-mastery through non-violent disciplines like material-breaking drills, yet combat reveals cunning pragmatism. He berates Retsu for meddling in his duel while secretly exploiting openings against Yujiro. Post-tournament surgeries stabilize his condition, as hinted by an attendant’s oblique report to Retsu. Liu Kaioh’s legacy persists through Retsu’s continued growth in Chinese Kenpo, cementing his influence as a mentor who molds warriors bound to honor, resilience, and the relentless pursuit of martial perfection.
