Kaioh Samwan is a Thai martial artist bearing the Kaiou title, awarded by the Chinese Martial Arts Association for exceptional combat prowess. He stands 25 years old during the Raitai Tournament, with a tall, slender physique and defined musculature. Samwan integrates Muay Thai with Chinese Kenpo in his fighting style. His Kaiou distinction stems from demonstrations of remarkable skill, including childhood interaction with a cobra and a near-destruction of a stone column via a kick. Limited on-screen engagements leave his full combat capabilities largely undocumented. At the Raitai Tournament, Samwan confronted Kaiou Kaku, Supreme Grandmaster of Chinese Kung Fu. The match ended abruptly within eight seconds when Kaku disrobed Samwan and incapacitated him with a groin strike, securing a swift victory. Humiliated by this defeat, Samwan later attacked Yuujiro Hanma in fury. Yuujiro overpowered him instantly, slamming him into the ground while mocking his inexperience and lack of seasoned combat judgment. Samwan exhibits pride and acute reactivity to humiliation. His background includes training under Ryuushou So and grandmaster Kaiou Kaku, though the nature of these relationships remains unelaborated. His documented narrative arc and appearances are confined to these tournament events, with no further character development or media extensions.
