Trying to Raise a Hybrid

Trying to raise a hybrid. That is what Will must do, after Grell saves an infant demon, and refuses to let him die. Turning him into a shinigami, making them one of their own, is the choice they make. But how far is William willing to take this? Can he raise and protect a kid who is part demon? Especially when the kids past come lurking up? (Some Grelliam)(May be minor violence...)
