Spirit Guardian of Lunar Tsuki

I still need to fill in some of the gaps in his back story but basically, Tsuki did something he shouldn't have though he had good intentions, so Soul was forced to sentence him to mortality. He was then born as a wolf named Silver, though being as mentally powerful as he is, a part of his memories stayed intact deep within Silver's sub-contusion. For now Silver just thinks Tsuki is a spirit trapped within his body.
