Hou Ken is one of the "Three Great Heavens" under Zhao and has a deep-seated hatred for Ou Ki, who was also known as Kyou, one of the Six Great Generals. Despite considering himself to be a Bushin, he is actually an unsuccessful Path Seeker. Most of his time was spent training in the mountains with his guandao. During the conquest of Bayou, he fought against Kyou and effortlessly cut through her elite bodyguards before she arrived on the scene. In combat, Kyou was killed by him, but he was severely wounded by Ou Ki, who gave him a scar across his face and riddled his body with arrows. After recovering from his wounds, Hou Ken spent another six years training before being approached by Ri Boku to take part in Zhao's plans against Qin. While his strength is 100, his leadership and knowledge are unknown.
