Key Events

 * The person Kimihito confronted and suspects to be the Grimoire Arbatel in disguise is Ms Honma Shiori from the library committee. Although Shiori initially denies this, she eventually confirms Kimihito's suspicions and shows him her true form after he confronts her with proof that supports his suspicion.
 * Kimihito got it from Zombina when she explained to him in Chapter 78 that unlike rom-com fans, rom-com Otaku don't want to enter the world of a love comedy themselves, since what she loves about rom-coms is the love and the lovers' relationship itself. So Arbatel would just silently watch the other students instead of having a relationship with someone herself.
 * Zombina's explanation and the photos Ms Smith took of the student couples turned Kimihito's suspicions on the library committee, as the group, including Shiori, was always present and observing the event, when a student couple fall in love. He narrowed his suspicions to Shiori since she was the only person in the entire school, including the other committee members, who was not in a romantic relationship with anyone.
 * Arbatel reveals that she didn't brainwash Kimihito on purpose as she wanted him to play the role of a harem rom-com protagonist since he lives together with seven Liminal girls. She also explains that she can't abide that kind of rom-com, and that she harbors a personal grudge against Kimihito, considering him as a polygamist and pathetically indecisive for not being able to pick one of the seven girls and live with her in a steady relationship.
 * Arbatel also explains that she brought Kimihito into her word specifically to change his "filthy harem obsessed heart". However, since that didn't work, she tries to use her magic directly against him, whether it's to brainwash him or make him to one of the school's six mysteries. However, that doesn't happen because another student crashes into Arbatel, causing her to experience her own rom-com.
 * Since Arbatel is still the grimoire, the world she created responds to her feelings. When Arbatel got excited, Kimihito heard some sort of loud heart racing, and the school yard also started to blur, presumably because it was created by Arbatel's mind and Arbatel was unfocused.
 * Having experienced some kind of rom-com herself, Arbatel doesn't think she can be someone who can fall in love at first sight. For this reason, she feels that she no longer has the right to look over this "perfect world" anymore and then releases everyone whose consciousness she had absorbed.
 * Kimihito, his household girls, the MON-Team and Ms Smith are back in the Kurusu house, and everyone else has also regained consciousness.
 * Tionishia has returned to her original size after exiting the rom-com world.
 * Since all the Grimoire people have started new relationships, everyone has decided not to blame Arbatel and in fact, people even praise Arbatel and send her petitions from all over the world.
 * According to Zombina, the extraspecies laws that say humans and Liminals can't harm each other aren't clear in Arbatel's case, so the charges aren't enough for an arrest either.
 * While most of the people who were in the Grimoire are doing well, Ms Smith still seems woozy and in trance believing she is still a student. However, most of the protagonists take this fact with amusement.
 * The school arc ends.

Trivia

 * Although the group ends up back in the normal world at the Kurusu house, Lala and Suu don't appear in this chapter.
 * When Kimihito shows the photos to Arbatel, a Matango girl can also be seen among the Liminals on the next page. This seems a bit odd since Matangos are considered a dangerous species due to their hallucinogenic spores, possibly implying that since the events of Volume 11, Matangos are now allowed to participate in the Cultural Exchange Beetween Species Program.
