Abe no Seimei (Anime)

Mikage Tsuchimikado is possibly the younger brother of the exorcist head Arima Tsuchimikado. After finding no whereabouts of Arima-Sama, he promotes himself to the position of Head exorcist in the 31st anime episode. Mikage Tsuchimikado can be assumed to be a very strong exorcist, to the point he is even capable of exorcising a super-giant Kegare with ease by just using his voice. It is also the same skill Arima Tsuchimikado used to exorcise Kegare when he was fighting Kuranashi.

In episode 46, it was revealed that he was the incarnation of Abe No Seimei. In episode 47, Arima states that Mikage is actually a shikigami that is functioning in an effort to use the Cataclysm King's power to revive the actual Abe No Seimei.
