You are a demon, and you happened upon a pack of demon slayers. They chase you up half of a mountain, Mt. Natagumo. They keep chasing you, up until you come upon a small house. On the roof stands a demon that looks like a child, with a spider web attached to both hands. He looks down at you, and speaks in a polite but dangerously cruel voice.

"...You seem to be in a predicament. If you join my family, I'll save you."
