The Conclusion

is chapter 19 of the Beelzebub manga.

Summary
Natsume overhears a group of students at Ishiyama High talking about Kunieda and Oga fighting because Oga supposedly beat her underlings. Having seen what really happened with Oga with Nene and Chiaki, Natsume is confused.

On the rooftop, Kunieda and Oga are engaged in fighting. Watching the two, Ikari recalls Miwa’s effective plan of taking down Kunieda’s underlings. Miwa, being transgender, remarks that he knows girls well enough. Ikari praises him for noticing the “queen”, Kunieda, fell in love with Oga. Miwa is offended and grabs Ikari’s head, demanding him to say who the queen is. Ikari pleads that he is the queen and apologizes to him. Miwa lets go, claiming two queens at Ishiyama High are unnecessary.

Nene, finally realizing that the MK5 set Oga and Kunieda up, is getting surrounded by them. Kunieda asks Oga why he won’t attack him back, to which Oga tries to accommodate to Beelzebub, whom begins crying. Dissatsified, Kunieda performs a sword dance at Oga, successfully striking him. Nene is now backed into the corner of the stairs by the MK5. Shimamura points a pistol at her head, ready to murder her. Just before Nene gets shot, Natsume saves her by pulling Shimamura’s pistol away from her. He tells Nene to leave, claiming to finish off the MK5 in just a minute.

Oga is now lying on the ground on the rooftop in front of Kunieda. Nene rushes out the stairs to try to tell her that the MK5 was responsible for the misunderstanding between her and Oga. With Oga now lying on the ground, Ikari and Miwa begin to approach Kunieda to fight her. Suddenly, Oga rises into the air. Landing in front of Miwa and Kunieda, he angrily demands Miwa not to interrupt Beelzebub when he’s finally able to control himself. Oga grabs Miwa’s head and slams it onto the ground, to Kunieda’s surprise.
