Beelzebub

Beelzebub (Japanese: べるぜバブ Hepburn: Beruzebabu) is a Japanese manga series about a first year student at a school for juvenile delinquents, written and illustrated by Ryūhei Tamura. Beelzebub was first published in 2008 as a one-shot by Tamura in issue 37–38 of Weekly Shōnen Jump, subsequently winning the fourth Gold Future Cup.

The story follows the “strongest juvenile delinquent”, Oga Tatsumi, a first year in Ishiyama High—the school for delinquents. One day while sleeping next to a river, he sees a man floating down it; he pulls him to shore and the man splits in half, revealing a baby boy.

Oga meets and fights Hajime Kanzaki, the first member of the Touhoushinki and the one who is closest to dominating the school; however, Oga defeats Kanzaki, which causes Beel to find him even more appealing.
