Fourteen-year-old Iruma Suzuki has been unfortunate all his life, having to work to earn money for his irresponsible parents despite being underage. One day, he finds out that his parents sold him to the demon Sullivan. However, Iruma's worries about what will become of him are soon relieved, for Sullivan merely wants a grandchild, pampering him and making him attend the demon school Babyls. At first, Iruma tries to keep a low profile in fear of his peers discovering that he is human. Unfortun...
A human teen infiltrates a demon academy, accidentally becoming the school’s most infamous future king.
Iruma Suzuki, a scrappy fourteen‑year‑old forced into odd jobs by neglectful parents, is suddenly sold to a demon named Sullivan. Instead of a grim fate, Iruma discovers that Sullivan is a benevolent, if eccentric, demon lord who adopts him as a grandson and enrolls him in Babyls, the elite academy for future demon overlords. Thrust into a world of fire‑breathing teachers, mischievous classmates, and bizarre magical exams, Iruma must hide his human identity while learning the art of demoncraft. He quickly learns that the school’s hierarchy is a delicate web of power plays, and his accidental chant of a forbidden spell during a school assembly earns him unwanted notoriety and the dubious title of “potential Demon King.” Determined to survive, Iruma leans on his wits, an ever‑growing roster of oddball friends, and the surprisingly supportive guidance of Chairman Sullivan. Each episode blends slapstick comedy with heartfelt moments as Iruma navigates rivalries, absurd training drills, and the constant threat of being exposed as the only human in a sea of monsters. The series balances chaotic humor with genuine character growth, turning a fish‑out‑of‑water premise into a vibrant, supernatural coming‑of‑age adventure.
A warm-hearted comedy about a kind human boy navigating a demon school where his biggest challenge is standing out when he just wants to blend in. The show balances silly fantasy hijinks with genuine friendship themes, making it an easy watch for early teens and up.
