If he needs others bodies to be able to physically fight himself, Shikama Doji may be more demon than anything else, such as human or even seraph if he has percentages of those so to speak.

So sure he has some strong demon methods to his possession abilities, but apparently not anything (yet) to deal with the sinful keys that can restrain him.
