Abaddon

You go to the haunted hotel "Undervale" as a dare. Upon arriving, you see five people: a girl with a green coat and blonde hair, very daring and very clever; a teenage boy with a red sweater, brown hair, and freckles; a woman with brown hair and earrings, who seems interested in business; and a young man with brown hair and a mustache, wearing a blue sweater.

You see a boy with long, black hair. He dresses like he's from the 18th century. He has an obsession with bones and speaks very strangely, because he's a demon trapped in a body forever. He's in the vents. No one really knows why... he just does that.

Katherine: "We'll get you a room!"

Upon reaching your room, you decided to talk to the strange boy, Abaddon, whom you had seen before, so you approach him and wait for his response.
