Plot Summary

The story follows Iruma Suzuki, a 14-year-old human boy who has had the worst luck imaginable. His neglectful parents literally sell his soul to a high-ranking demon named Lord Sullivan. However, instead of being eaten, Iruma find out that Sullivan just really wanted a grandson to dote on. Iruma is enrolled in Babyls School for Demons, where he must hide his human identity or risk being eaten by his classmates. Despite wanting to stay invisible, Iruma’s kindness and incredible survival instincts constantly land him in the spotlight, making him one of the most famous students in the school.

Main Characters

  • Iruma Suzuki: A human boy who can’t say no to requests. He’s a "dodgeball master" because he spent his whole life avoiding disasters.
  • Asmodeus Alice: A fire-wielding elite demon who becomes Iruma's fiercely loyal best friend after losing a duel to him.
  • Valac Clara: A chaotic, energetic girl who can pull anything out of her pockets. She provides most of the show's physical comedy.
  • Azazel Ameri: The student council president who is dignified and strong, but secretly obsessed with human "forbidden texts" (romance manga).
  • Naberius Kalego: Iruma’s stern homeroom teacher who accidentally becomes Iruma's familiar—in the form of a small, fluffy bird.

Why it is worth watching

The biggest reason to watch this series is the incredible character growth. Unlike some comedies where characters stay the same, the "Misfit Class" at Babyls actually develops and gets stronger together. The world-building is also surprisingly deep, with a ranking system and lore that keeps you invested in the plot. It’s a very comfy show, often compared to classics like Hayate the Combat Butler, but with its own unique demonic flair. You can find more detailed reviews and ratings on MyAnimeList if you want to see how much the community loves it. The humor is almost always on point, especially when it involves Iruma accidentally succeeding at things he is terrified of doing.

Conclusion

In a world of gritty and dark fantasy, Welcome to Demon School! Iruma-kun is a breath of fresh air. It balances comedy, action, and genuine emotion perfectly. Whether you start with the manga or jump straight into the anime, you’re going to fall in love with Iruma and his chaotic group of demon friends. If you haven't started this journey yet, you are seriously missing out on one of the best "feel-good" stories in the medium.
