Beelzebub

A delinquent teen becomes the reluctant dad of the Demon Lord’s infant heir.

Ishiyama High is a breeding ground for troublemakers, where the strongest first‑year brawler, Tatsumi Oga, reigns supreme. One lazy afternoon by the river, Oga rescues a drifting stranger who splits open to reveal a chubby infant. The baby, Kaiser de Emperana Beelzebub IV—affectionately known as Baby Beel—turns out to be the heir to the Demon Lord himself. Before Oga can even process the supernatural twist, a prim and proper demon maid named Hildegard appears, demanding that the boy be raised according to infernal protocol. What follows is a chaotic mash‑up of schoolyard brawls, demonic tantrums, and reluctant parenting. Oga, a hard‑boiled delinquent with a penchant for punching his way through problems, must now juggle homework, hallway turf wars, and the occasional infernal fireball that Baby Beel unintentionally summons. Hildegard, armed with centuries‑old etiquette and a dead‑pan attitude, tries to instill proper manners in a child who thinks a fireball is a bedtime story. Together they navigate a world where teachers are as fearsome as the underworld, classmates are more like rival gangs, and the line between human and monster blurs with every slap‑stick mishap. The series blends over‑the‑top action with slap‑stick comedy, delivering a relentless ride through teenage rebellion and otherworldly childcare.

A rowdy shounen comedy where a high school delinquent becomes unwilling parent to the Demon Lord's infant son, blending constant slapstick fights with baby-care chaos. Expect cartoonish violence, frequent toilet humor, and mild fan service wrapped in a surprisingly sweet found-family dynamic.
