Beelzebub

Oga Tatsumi is a notorious troublemaker whose life is all street fights and schoolyard dominance until a bizarre day when a crawling infant clings to his back and refuses to let go. That baby is Kaiser de Emperana Beelzebub IV, heir to the Demon Lord, and his sudden attachment drags Oga into a chaotic mix of childcare, supernatural conflict, and everyday high school messes. Oga resists at first, but the baby's presence reshapes his priorities, pulls in friends and rivals, and turns ordinary scuffles into battles with demonic consequences. The series keeps it energetic and humorous while letting relationships and loyalties grow without resolving every mystery right away.

Adapted from Ryuuhei Tamura's manga, the TV anime premiered in 2011, with Masahiro Yokotani credited among the creators. The show features a notable voice cast, including Miyuki Sawashiro as Beelbou, Katsuyuki Konishi as Oga Tatsumi, Shizuka Itoh as Hilda Garde, Takahiro Mizushima as Furuichi Takayuki, and Aki Toyosaki as Aoi Kunieda.

Critics and fans tend to praise the show for its fast-paced comedy and action, reflected in an average user rating of 8.271 out of 10 from 264 votes. Reviewers point to the chemistry between rough-and-ready Oga and the absurd innocence of Baby Beel, plus strong supporting work from Furuichi and Hilda. The series balances slapstick fighting scenes with quieter moments about responsibility, friendship, and loyalty, and the voice performances are often singled out for elevating the material.

The central image of a delinquent hauling a demonic infant quickly became a memorable visual among anime fans, spawning fan art, cosplay, and frequent online references. Its mix of over-the-top school brawls and family-style bonding helped shape later comedy-action shows that pair odd couples, and it still enjoys an active fanbase that celebrates its loud humor, recurring character rivalries, and surprising moments of warmth.
