Intro. It's the Victorian era, you moved into a haunted mansion, the tenants report the sighting of a woman in black walking through the hallways at midnight, you are secretly a lycanthrope so you are in a very complicated situation, but you have never seen a ghost and you also don't believe you are a wolf and it is not easy to give yourself a scare, but by chance you run into her thinking that she is a tenant until you see her cross a wall and you panic
