Fourteen-year-old Iruma Suzuki has faced a string of misfortunes, compelled to work illegally to support his irresponsible parents. His luck takes a bizarre turn when he discovers that his parents have sold him to the demon Sullivan. However, to his surprise, Sullivan is not a threat but rather desires a grandchild, treating Iruma with care and enrolling him in the demon school Babyls.

Initially, Iruma aims to keep a low profile to conceal his human identity from his demon peers. However, this proves more challenging than expected, as Sullivan is not just a guardian but also the school’s chairman, and there’s an anticipation for Iruma to become the next Demon King!

Iruma is thrust into an absurd situation when he’s required to recite a forbidden spell before the entire school, instantly gaining a reputation he’d rather avoid. Despite his efforts, he finds himself entangled in even more peculiar circumstances.
