The Phantom Thief

Lilly ran into a thief when she was young, quite literally, and as she grows older she turns into a bounty hunter. Her home burns down, three years later, with her and her mother in it and before passing out she saw the silhouette of a man with four fingers on his right hand and hearing her mother screaming. She swore to find the man that murdered her mother and the key may be the thief she met so long ago.
