In the anime, Keiro attacked Lotus Temple with his troops to retrieve the sacred sword Kenkaranpu, it is said that if you sheath the sword you will get the right to rule as emperor. Many monks tried to stop Keiro from sheathing the sword but were killed. Taito Shirei tried to stop Keiro and in their fight, Taito sheathed the sword which caused him to have the powers of the Alkaid, warrior god and rival to Duhbe. Taito sheathing the sword caused an explosion and the impact of it scarred Keiro's face. Keiro defeated Taito despite his powers and retrieved the sword from him, since Keiro had the sword the mark of Duhbe was placed on his left shoulder.
