Ishiyama High School harbors the most violent delinquents in Japan, and none commands more dread than first-year brute Tatsumi Oga, known throughout the district as the Rampaging Ogre. While beating rival thugs along a riverbank, Oga retrieves an oversized man drifting downstream. The man splits open to reveal a green-haired baby who immediately latches onto Oga. The infant is Kaiser de Emperana Beelzebub IV, the youngest son of the Great Demon Lord, dispatched to Earth to eradicate mankind once he finds an adoptive human parent sufficiently cruel, sadistic, and strong enough to nurture his demonic impulses.

Bound by a demonic contract, Oga suffers lethal electric shocks whenever separated from Baby Beel by more than fifteen meters. Accompanied by the demon wet-nurse Hildegard and his long-suffering best friend Takayuki Furuichi, Oga seeks an opponent wicked enough to pass the toddler off to. This search triggers brutal street brawls against the Tohoshinki—Ishiyama High's four ruling warlords, Hajime Kanzaki, Hidetora Tojo, Aoi Kunieda, and Tatsuya Himekawa—before escalating into high-stakes combat against rogue royal demons from the 34th Division of the Pillar Squads.

What to Expect

Beelzebub pairs unhinged delinquent gang warfare with slapstick parenting comedy and escalating demonic energy systems. Combat begins as raw street brawling, relying on brass knuckles, blunt weapons, and heavy impact choreography. As Oga forms a deeper bond with Baby Beel, the series introduces the Zebub Spell, Super Milk Time, and Demon Energy manipulation, enabling Oga to channel high-voltage demonic power directly into physical strikes against elite supernatural combatants.
