Lyrics
だだだ　だだだ

なにさまだ　お子さまだ

余命はざっと7、80年

お前はすでに　だだだだだ

なにちゃんだ　赤ちゃんだ

2時間おきに号泣だ

夜更けにおっぱい要求だ

ママが無視なら　一応

パパのおっぱい吸ってみるのだ

だだ　だだ　だだ　だだこねる　だだだだだ

ファミレスのオモチャが欲しいのだ

だだ　だだ　だだねだる　だだだだだだ

聞き訳ないので　おなじみだ

だだ　だだ　地団駄ふむ　だだだだだ

どんぐりもらってゴキゲンだ

だ　だ　だ　だ　だまされた

（だめだこりゃ）

だだだ

Modifications following the 2011 Tōhoku earthquake and tsunami
Following the 2011 Tōhoku earthquake and tsunami, the opening sequence for the series was modified for Episode 10 to remove all references of earthquakes, flooding and mass graves. These modifications include the following:
 * The pre-opening sequence where Oga spots Arandron floating down the river and opening himself up to release Beelzebub was precluded. Instead, Beelzebub is simply seen rising out of the bottom of the screen to latch onto Oga.
 * Just before the title screen appears in the opening sequence, a demonic volcano is normally seen erupting and shaking the ground as Beelzebub flies out of it. This scene has been replaced with various close-up shots of Beelzebub from past episodes.
 * After the scene where Oga fights a large crowd of teenagers alongside Beelzebub dancing, the two would normally be seen standing triumphantly on the pile of teenagers Oga just fought, all lying on the ground among them. These teenagers (and parts of Oga's and Beelzebub's legs) had been covered over by an alternating light and dark background rotating across the bottom half of the screen.
