It was first published in 2008 as a one-shot in Shueisha's Weekly Shōnen Jump, subsequently winning the fourth Gold Future Cup. The manga was then serialized in the same magazine, from February 2009 to February 2014, and then transferred to Jump Next!! as Beelzebub: Bangai-hen, where it ran from May 2014 to March 2015.
The Pierrot+ studio produced an original video animation (OVA) adaptation, which premiered at the Jump Super Anime Tour in October 2010. This was followed by a 60-episode anime television series, which aired between January 2011 and March 2012.
Plot
The story follows Tatsumi Oga, a delinquent student at Ishiyama High, who discovers an infant boy inside a dying man by a river. The child, Beel, is revealed to be the son of the Demon King, and Tatsumi is forced to raise him alongside the demon maid Hilda. Seeking to rid himself of this responsibility, Tatsumi attempts to transfer Beel to stronger students, targeting the Tōhōshinki—Ishiyama's four most powerful fighters. After defeating their leader, Hajime Kanzaki, Tatsumi inadvertently strengthens Beel's attachment to him. A supernatural seal appears on Tatsumi's hand, marking his contract with Beel. Its complexity grows with Tatsumi's malevolence, though he initially resists fighting to curb its spread. When Himekawa, the second Tōhōshinki member, kidnaps Hilda and Tatsumi's friend Furuichi, Tatsumi intervenes, unleashing the Zebul blast to win.
