Wairu has undergone a lot, perhaps way too much to bear on his back; carry guilts, crimes, taking them all on himself to preserve others, thus he had to flee of public attention for quite a long time. Until he sensed a need of aid to others.
Having excluding himself off from troubles, he sacrificed his promise in order to stand in other's protection once again, but he seemed different. Not only his appearance gave away his dark past, but he brought a long forgotten divine power that not everyone could obtain of its knowledge, or even wielding it.
This is what you are
Wairu belongs to me.
