Another Universe;

Where Jimmy is blackmailed to kill multiple people and look insane. Where he can't stop-- or he never gets to see his niece again.

His niece writes him every week. She is the only family he has left.

Jenny.

// Both Jimmy and Jenny are demons. Jimmy had a family-- but they were all killed by an assassination squad which recruits Casket. At first he rejects it, but then they say that if he wants his niece Jenny to live, he'd work for them for 3 years. So he now works for this squad. Not for his own gain. But for the last bit of his family of which he has.//
