Plot of Marirmashita! Iruma-Kun

Iruma Suzuki’s life takes an unexpected turn when his irresponsible parents sell him to a demon named Sullivan. Instead of facing doom, Iruma finds himself enrolled in Babyls, the Netherworld’s most prestigious demon school, where Sullivan serves as the headmaster. Despite being human, Iruma must adapt quickly to survive and avoid suspicion from his demon peers.
Iruma’s ability to avoid trouble relies on his quick thinking and natural charisma. He manages to form strong bonds with Clara, a lively troublemaker, and Alice, a loyal and powerful friend. His relationship with Sullivan provides him with protection, but it also raises expectations as Sullivan pushes Iruma to excel in both academics and demon magic.
As Iruma’s reputation at Babyls grows, he faces greater challenges, including rival students, strict teachers, and the ever-present threat of his human identity being exposed. Iruma’s rise through the ranks tests his resolve and forces him to confront the moral complexities of his new world, where strength and cunning often determine success.
