[Discussion] Beelzebub

SUMMARY
The strong delinquent Oga (nicknamed Ogre, Demon, or "it'd be alright if
he'd just die" by other delinquents) picks up a baby that turns out to
be the son of the Great Demon King! Chosen to raise the baby until he's
in age of destroying mankind, together with the demon maid Hilda,
they're sure to make mankind die... of laughter!

The story follows his life with the child and at the delinquent school.
Oga attempts to "pass on" baby beel to other students at Ishiyama. If
Oga can find someone more evil and stronger than him, Baby Beel will
attach to that person instead of Oga. After subsequently fighting and
defeating all members of the Tōhōshinki and in the process, destroying
Ishiyama High itself, Oga and company are transferred to Saint Ishiyama
Academy, which appears to be a direct opposite of the delinquent school -
and it's there the real story begins.
