About the Demon Slayer Kimetsu Academy Manga Volume 3

Fall's here, but things are only heating up at Kimetsu Academy! Halloween turns scarier than ever when one of the Twelve Kizuki wanders into a spooky water balloon battle, though that's got nothing on how frightening it is when the principal sees the state of the teachers' lounge. Then there's trouble with a demon selling snake oil, all while Mitsuri explores mascot art, a terrible drawing is misunderstood, and Uzui's wives check the cafeteria's suggestion box.
