I was seriously scared of this arc when I see Sano of all people also got possessed. Dude's already wound up guilty during Kyoto arc, now he and all his friends end up attacking Haruaki too?! AAAAARRRGHH-
I think that's exactly what the kitsune want him to do?
It would show that he's exactly like Abe no Seimei, so Haruaki needs to find another solution. One that doesn't involve exorcising yokai to get what he wants.
