Beelzebub

is a Japanese manga written and illustrated by Ryūhei Tamura that appeared in Shueisha's Weekly Shōnen Jump magazine since February 2009. Beelzebub was first published as a one-shot by Tamura in Weekly Shōnen Jump's 2008 volume 37-38, where it won the fourth Gold Future Cup. It was then serialized on the same magazine starting in its thirteenth volume.

Plot
The story follows Tatsumi Oga, the "strongest juvenile delinquent". He is a first year student in Ishiyama High School, a school with a heavy presence of delinquents. The story begins as Tatsumi is telling the story of how he found Beelzebub to his best friend Takayuki Furuichi. One day, while taking revenge on people trying to kill him in his sleep, supposedly fishing, he sees a man, revealed as Arandron, floating down the river. Tatsumi pulls him to shore and he splits in half, revealing a baby boy. This boy is revealed to be Kaiser de Emperana Beelzebub IV, the son of the Demon King, and Tatsumi has been chosen to be the one to raise him with the baby's maid Hilda. The story follows Tatsumi's life with the child and at Ishiyama High. The early chapters of the manga follow Tatsumi as he attempts to pass on Beelzebub to other students at Ishiyama High. The theory is that if Tatsumi can find someone more evil and stronger than him, Beelzebub will attach to that person instead of Tatsumi.
