Samwan Kaiō, a Thai-born martial artist, earned the prestigious Kaiō title from the Chinese Martial Arts Association in recognition of his exceptional prowess. At 25 during the Raitai Tournament, he possesses a tall, slender frame with defined muscles and black hair. His primary fighting style blends Muay Thai with Chinese Kenpo, reflecting his background and training lineage under master Ryuushou So and grandmaster Kaiō Kaku. Samwan demonstrates significant combat abilities, including near-destruction of a stone column with a single kick. His childhood proficiency handling dangerous animals like cobras hints at early-developed reflexes. During the Raitai Tournament, he faced Kaiō Kaku but suffered a swift, humiliating defeat in eight seconds; Kaku exploited a vulnerability by pulling down Samwan's pants and incapacitating him with a targeted strike to the groin. This loss deeply affected Samwan, prompting an immediate, rage-driven attack on Yuujirou Hanma. Yuujirou effortlessly subdued him, slamming him into the ground while mocking his inexperience and emotional reaction to the prior humiliation.
