Tatsumi Oga is the undisputed king of delinquents at Ishiyama High, a school notoriously packed with ruthless brawlers and violent miscreants. Oga's violent routine takes a bizarre turn when he encounters a giant man floating down a river. Upon pulling him ashore, the man splits open, revealing a strange baby inside. This is no ordinary infant; he is Kaiser de Emperana Beelzebub IV, the son of the great Demon King, sent to Earth to destroy humanity. To Oga's dismay, Baby Beel instantly imprints on him due to his unparalleled strength and malice, forcing the delinquent to act as his surrogate father.

The demonic arrangement binds them physically—if Oga moves too far away from the infant, he risks a lethal electrocution. Accompanied by the baby's fiercely loyal demon maid, Hildegard, Oga is dragged into a bizarre domestic life while simultaneously defending his title against rival high school gangs and supernatural entities. To rid himself of this unwanted responsibility, Oga searches for someone stronger and more evil to pass the baby onto, leading to constant showdowns. Rich in slapstick humor, frantic martial arts battles, and highly strategic uses of demonic pacts, the narrative beautifully balances high-stakes fantasy combat with the heartwarming, absurd realities of raising a magical baby.
