Chapter 117

As Oga is frustrated with the old man's appearance, Kanzaki leads all the Ishiyama High students back into their own school, but not without expressing their gratitude to Sadohara. Himekawa chooses to take a helicopter just to brag to everyone about getting to Ishiyama High first. Meanwhile, as the old man loses Oga on the rooftop, he confronts Saotome, Kunieda's grandfather Ittōsai and the Saint Ishiyama Academy principal Genma Isurugi. Koma-chan detects a very powerful Demon and rushes Kunieda to school. Meanwhile, the Ishiyama High students begin deciding who gets to graffiti first until two construction workers take away the Ishiyama High plaque. Saotome, Ittōsai and Isurugi start by attacking the mysterious man, actually revealed to be Behemoth himself. As Hilda tries to hide Oga after sensing him, Behemoth claims that he merely wants to greet everyone as he built a new school for En. To the surprise of the Ishiyama High students, they see their school plaque being replaced with one reading Akumano Academy.
