Will-O-Wisp

The Will-O-Wisp is the first boss encountered in the Afterlife, in The Boundary Abyss. She has been created from the mutated soul of a little girl, whose dad died in the Vietnam war and whose mom hanged herself one week later, leaving her to discover the body, with her teddy bear, Mr. Bear, for sole company. A demon in disguise arranged for her parents funeral and killed her painfully and brutally, after telling her he will send her to see them again.
