Aoi returns to the classroom moments after leaving, and finds the two of them in the room. She realizes that they have been there all along, and goes on the offensive. During the conflict Baby Beel exits the classroom through an open window and climbs into Sadohara's sports car, and locks the door behind him, which Oga is unable to pull open.

Oga, accompanied by Aoi, goes searching for Kazuya to get more information about the 6 Holy Knights. Meanwhile, Furuichi runs into an old friend, Miki. He warns Furuichi to stop Oga getting involved with the six, and tells him that the six wear badges to identify them as Holy Knights, before promptly revealing himself to be one of them. Oga finds Azusa while looking for Kazuya, and is quickly interrupted when two of the Knights show up, revealing themselves to be Alex and Sakaki.

Izuma starts serving using a fighting technique to power the balls towards Kunieda with such power that she's unable to dig them out. Kunieda's arms are burned badly from trying to deflect the balls, and she substitutes for Furuichi, who proves to be totally useless.

Thus upon fighting, he introduces his new technique called the "Zebul Emblem" and "Super Milk Time" (which he learned while training with Saotome. Black Baby Beel and Baby Beel fought over the milk and Oga decided to drink it himself so Black Baby Beel And Baby Beel don't have anything to fight on). To remove the divider between Oga and Baby Beel, he drank the milk to suddenly become powerful. Eventually, the demon power from Baby Beel increased as he drank more, and Oga defeated the two Pillar heads. Finally drinking it all, he fights the Pillar Head Naga while merged with Baby Beel. Thus, he became Baby Beel himself with wings, and scattered the Zebul Emblem to surround the Pillar Heads.

Meanwhile, Oga and Baby Beel had actually spent that week in a spa in the Demon World. At the same time, Lord En and the 34 Pillar Division come back to the human world on orders from the Great Demon Lord. However, now that Akumano Academy/Ishiyama High School has been destroyed once again, the 34 Pillar Division decide to take their class to St. Ishiyama Academy, upon instruction that they will continue to destroy humanity, along with the Great Demon Lord's army. Yet, Hilda updates that the Great Demon Lord, being a flake, changes his mind instantly and takes back destroying humanity. But this can only mean one thing——Beelzebub must return to the demon world. Baby Beel declines accepting the truth, and overnight runs away and cuts the link between him and Oga. Flying overhead, he looks over the times they've spent together and the people he's met, while everyone is out looking for him. In the end, Oga finds him by the river where they met, and consoles him with his favorite croquettes, saying that he's 'his Baby Beel' whenever Beelzebub will think back to the human world; and that he should fight back for what he wants, and come back on his own terms himself. Baby Beel begins crying, and Oga welcomes him into his arms, allowing him to cry as much as he wants since this is his last time, despite the pain, only to find out it doesn't hurt since Baby Beel isn't shocking him this time. Baby Beel becomes resolved, and the Ishiyama students see everyone off on their transfer to the demon world, Oga giving him an affectionate gesture like rubbing their heads together, of course, with Beelzebub rubbing harder at him. Oga then walks away, and sometime in the future, Ishiyama becomes the strongest like before, with Oga, Tojo, Kanzaki, and Himekawa fighting others by the same river. Hilda and Beelzebub comes back with a grand entrance, stating that the Great Demon Lord ordered Baby Beel to destroy humanity once again. Oga smiles and declines raising him, even though he knows he will, Baby Beel shocking him like before.
