Beelzebub Part 2 contains episodes 31-60 of the anime directed by Nobuhiro Takamoto.

With Ishiyama High destroyed in the aftermath of Tatsumi's fight with Tojo, the young punks are transferred to their sister school, Saint Ishiyama High. But all a new school really means is new challenges... and not the academic kind!

The Six Holy Knights of Saint Ishiyama are said to be the strongest around, even more powerful than Ishiyama's top guys. With the Ishiyama crew being looked down upon, tensions rise, until there's no choice left but to battle it out on the school roof. But the fight ends without anything being resolved, and expulsion seems eminent... unless, that is, Tatsumi and company can defeat the Holy Knights in a volleyball game. But there's more than just school fighting action going around, as Baby Beel is watching all of Tatsumi's actions, learning the best ways to subjugate humanity. While the kids fight, will the world end?
