Hannah is a normal girl with a pretty average life. One day she’s strolling through the forest and falls into a black hole which is a portal to the hidden demon world below. She ends up in a demon duke's mansion, in his bedroom. She begs him to let her hide here, to send her home and not kill her. He agrees, but there’s a catch. He won’t kill her as long as she does as he asks. Should be okay, right?
