- Title: Welcome to Demon School! Iruma-kun - Volumes: 1-23 - Publisher: Akita Shoten - Series: Weekly Shonen Champion - Anime Adaptation: TV Anime - Genre: Shonen Manga - Condition: Excellent Thank you for viewing. I am gradually listing manga I have collected as a hobby, due to reorganizing my bookshelves. The manga I own were almost all purchased new and have been carefully stored. There is no sun damage to the spines. However, since they have been handled by people once, they are not "new." Please take a close look at the images. I am not selling individual volumes. No need to ask to purchase. Also, no claims or returns are accepted.
