Thank you for viewing! This is a set of 5 purchase bonus papers from "The Main Actor in the Demon World is Us!" There are no noticeable stains, but please refrain from purchasing if you are concerned, as it is stored by a private individual. I liked the Utsu Corps (Dai-sensei, Shoppi, Chino), so the illustrations on the papers are mostly of them. Instant purchase is OK. Please feel free to ask if you have any other questions.
