Selling your soul? Whole different line of magic. Won't buy you anything but a lifetime of servitude and won't help your dad either.
I agree with the suggestions of Dr. Martin and my brother or sister. When I first got here, several members of my now-husband's pack got together and were able to exorcise a Nogitsune from you with pretty much crack team. So just because it's not automatically in their skillset doesn't mean it can't happen, all right? We'll figure something out.
