Where it came from
Mairimashita! Iruma-kun, or Welcome to Demon School! Iruma-kun, began serialization in Akita Shoten's Weekly Shōnen Champion in March 2017. Created by mangaka Nishi Osamu, the series follows Iruma Suzuki, a young boy sold to a demon who eventually finds himself navigating the halls of Babyls School for Demons. The narrative blends traditional shōnen tropes with a whimsical, supernatural premise, focusing on themes of found family and personal growth in an environment designed to be antagonistic.
Nishi Osamu’s character designs lean into a vibrant, expressive aesthetic that balances the chaotic energy of the demonic setting with the earnest, relatable nature of the protagonist. The series gained significant traction for its lighthearted subversion of the isekai genre, leading to a successful anime adaptation produced by Bandai Namco Pictures. It is widely regarded for its world-building and character development, having garnered a loyal international following since its debut.
