Isn't This Bad?

is chapter 197 of the Beelzebub manga.

Summary
A still-transformed Oga starts bemoaning at the fact that he forgot to ask about Nasu's Demon. He turns to Hilda but discovers that she is gone.

Elsewhere, the young individual, who has decided to rest following Oga's victory, prepares to eat cup ramen as he talks to an acquaintance over the cell phone. While in the middle of a conversation, he realizes that Hilda has arrived and is now eavesdropping on him. Hilda declares that she will first punish him for posing a threat to her master and draws out her sword; nearby, Alaindelon prepares to attack the young individual as well. The young individual, however, escapes using a Teleportation Jewel on his tongue, surprising both of the other Demons present.

Hilda ends up returning to the scene of Oga's and Nasu's battle; as she arrives, all of the doppelgängers, inside and outside the classroom, suddenly begin melting into nothing but dark liquid. She reveals that there is a possible mastermind behind everything and warns the delinquents about the young individual's shadowed party. Hilda adds to Oga that the next Spellmaster has already targeted him. Afterwards, she and Alaindelon leave to report their findings to the Kingdom in the Demon World.

Oga remarks that he can take on anyone that is next to come after him regardless of who they are. Afterwards, when Furuichi reminds him that he is still merged with Baby Beel, he and the infant separate their bodies; unfortunately, due to using Super Milk Time for an extended amount of time, their souls have swapped to the other's body. An excited Baby Beel then starts running out into the hallways as Oga and Furuichi look on in disbelief. The two then begin searching for the Demon infant while a confused Kanzaki asks about the situation.

Meanwhile, Aoi enters a classroom filled with "Reborn Red Tail" girls. She inquires of their leader's location and adds that they alone were supposed to speak together. However, as it turns out, Ringo is busy dealing with other matters at the present time.

Akahoshi washes his hands in the male restrooms while speaking to his subordinate, Shigeru Shigemori, about the current battle between Oga and Nasu. He reassures the latter that Oga will not lose to anyone but himself; with that said, they then notice Baby Beel, who is still inhabiting Oga's body, running across the hallways.

Baby Beel eventually stops when he sees a young woman in the hallways: Ringo Hōjō. She recognizes him as Tatsumi Oga and suddenly begins to strip, asking that he spends time with her.
