Iruma Suzuki is the ultimate pushover. His kind nature and inability to say no have always made him an easy target for exploitation. But nothing could have prepared him for what his terrible parents did to him—they sold his soul to a demon! Now, Iruma finds himself in the Netherworld, a world ruled by demons, where humans like him are nothing more than myths.
To his surprise, the demon who bought him, Sullivan, doesn’t want to eat him. Instead, he wants to adopt Iruma as his grandson! Sullivan, one of the most powerful demons in the Netherworld, is overjoyed to have a human grandson and treats Iruma with overwhelming love and care. However, there’s a catch—Sullivan wants Iruma to attend Babyls, the prestigious demon school, where he serves as the headmaster.
Thrown into this terrifying new world, Iruma has one clear goal: survive without revealing that he’s human! If his classmates ever found out, he’d be devoured in an instant. But blending in at a school full of demons is no easy task. From accidentally making a rival swear eternal loyalty to him, to being chosen as a student representative against his will, Iruma somehow keeps attracting attention.
Mairimashita! Iruma-kun Plot
Despite trying to keep a low profile, his survival instincts and unique skills from a lifetime of dealing with unreasonable people actually make him stand out. Whether it’s summoning a powerful familiar, dodging deadly spells, or acing impossible exams, Iruma keeps shocking everyone around him. The more he succeeds, the more his fellow students admire him, and the more trouble he finds himself in.
But life in the Netherworld isn’t all bad. He gains loyal friends, like the fiery and competitive Asmodeus and the hyperactive but lovable Clara, who make his new life a lot more fun. He even starts to enjoy his time at Babyls, despite the ever-present danger of being exposed.
However, being the “grandson” of one of the most influential demons comes with expectations. Sullivan dotes on him endlessly but also wants Iruma to become the next Demon King—something Iruma definitely doesn’t want! With powerful teachers, rival classmates, and mysterious forces lurking in the shadows, his days in the Netherworld are anything but peaceful.
Welcome to Demon School, Iruma-kun! is a fun, action-packed fantasy comedy about a human trying to survive in a school full of demons. Will Iruma manage to hide his true identity, or will his growing reputation bring him even more trouble? One thing’s for sure—his life in the Netherworld is just getting started!
