魔入りました! 入間くん [Mairimashita! Iruma-kun] #37

Volume 37 of Osamu Nishi's beloved supernatural comedy finds Iruma in full summer-fun mode — the cover shows him grinning broadly, hoisting a colorful inflatable ring above his head against a splash of bright water and vivid blue tones. It's a lighthearted, energetic snapshot of the series' signature charm, where even a human boy navigating the demon world somehow makes it look like a great time.
