One of Yoh Asakura's ancestors who lived around 500 years ago. Following his duty as a member of the Asakura family, Yohken entered the Shaman Fight of 500 years ago to defeat Hao Asakura, which he did, with the help of Matamune, Hao's former companion. One of his techniques is OverSoul 'Onigoroshi' (Demon Killer) - Yohken used this with Matamune, using his Shakujou as his medium. In the manga, it was the same OverSoul that Yoh used when he saved Anna from the Oni, although Yohken uses his Shakujou (ring-topped Buddhist priests' staff) as the medium.
