Not a lot; I'm not a psychic or a spirit medium or anything. [ a beat. ] Though, my boss is kind of psychic.

[ kind of... he just has this magatama, and it's filled with spiritual energy. it makes him find psychlocks in one's heart - so any secrets they're keeping can't be kept at all. ]

Body possession should almost be the same as channeling spirits, though... except, you know, it's not voluntary. Some charms would probably help get rid of the spirit? I'm not sure.
