A high-school delinquent suddenly finds himself the surrogate father of a baby destined to destroy the world when he grows up.

Oga Tatsumi is a violent punk at one of Japan's worst high-schools: Ishiyama High. One day, as he is dunking some weaker punks in a riverbed, he finds a vessel containing a green-haired baby by accident. However, the baby seems somewhat attached to him. Oga later discovers that baby is Kaiser de Emperana Beelzebub IV, or Baby Be'el for short, the son of the Great Demon King who is destined to one day destroy humanity. The Demon Lord, feeling bored, decided to send him to the human world with his wet nurse Hildegarde in hopes that whoever picked him up would be evil enough to raise him into a fearsome demon that will one day destroy humanity.
Not wanting this responsibility on his head, Oga tries to find a person even more evil than himself with whom to ditch the baby. This brings him into constant conflict with other top delinquents at Ishiyama High as he fights them just to make them take Be'el away, but keeps winning. Will he succeed in his quest, or is he doomed to remain the surrogate father of the baby who will destroy the world?
