Hilda has a nightmare about Oga's declaration back at the end of the fight against En's people, about how he wouldn't allow Beel to destroy the world. She wakes up feeling unnecessary, and angry at Oga, thinking that he wants to replace her. That Beel would love Oga more than he does her. At school a strange old man is looking for Oga, and when he finds him Oga just leaves. The rest of the Ishiyama class have found out that their school has been rebuilt, and they all head over to get a look at it and to be the first to graffiti it. Oga and Beel have lunch on the roof, and Hilda brings Oga's lunch, having thought Oga left the bottle of milk behind. She notices a strong demonic presence, and gets herself and the other two to cover, in time to see the old man from before, and Saotome, Aoi's grandfather, and the principal facing off against him. They reveal that he is Behemoth, and attack him, despite his insistence that he's only there to greet them as a neighbor. The Ishiyama students discover that their newly rebuilt school has been renamed Akumano Academy, and it is now a school owned by En. Inside the school a rather unfortunate and confused teacher is taking roll in a class full of En's Pillar Generals. The Ishiyama students break into the school, and are confronted by Agiel, one of the Pillar Generals. She easily takes care of two unnamed Ishiyama thugs, and is about to attack Nene, when Aoi interferes and faces off against Agiel, with Komainu's help.
