Forced to fend for himself from a young age, he developed remarkable survival skills, such as avoiding danger, reading situations, and enduring extreme conditions. These skills later become invaluable in the Demon World, allowing him to navigate difficult situations with ease.

His life takes a dramatic turn when his parents sell him to a high-ranking demon named Sullivan. However, rather than harming Iruma, Sullivan adopts him as his grandson, showering him with love, care, and an extravagant lifestyle that he never experienced as a human. Under Sullivan’s guidance, Iruma enrolls in Babyls Demon School, where he must keep his humanity a secret while trying to blend in with his powerful demon classmates. Despite having no natural demonic abilities, Iruma’s kindness, intelligence, and quick thinking allow him to rise through the school’s ranks, earning respect from both friends and foes alike.
