Beelzebub
Ishiyama High is a delinquent-only institution where constant violence and disorder are the norm. The most ruthless boxer in Ishiyama, first-year student Tatsumi Oga, has one unbreakable rule: don't cross him. Oga comes across a man floating down the river one day while he is standing by a riverbed. After being rescued by Oga, the man breaks in half to reveal a baby, who quickly latches onto Oga and develops a bond with him. This infant is known as Kaiser de Emperana Beelzebub IV, or simply "Baby Beel," and is the Demon Lord's son, though he is not yet aware of this. As if finding the future Lord of the Underworld weren't enough, Hildegard, Beel's demon maid, also confronts Oga. They work together to raise Baby Beel, despite the fact that they are surrounded by young offenders and supernatural forces and may face more difficulties than they can fathom.
