The Autumn Moon Inn sits on the mountainside of Autumn Moon Valley, near where a great demon that eats children is suppressed. To ensure safety, the owner has a strict rule: no children are allowed. When a tour group arrives, the owner discovers a mother traveling with her child and insists on turning them away, threatening to refuse the entire group otherwise. After some persuasion, the owner manages to send the mother and child away, but when night falls, trouble finds the inn nonetheless.
