Students of Grimoire High School

The Students of Grimoire High School are individuals of varying ages and races that have all been entrapped and hypnotised by the Grimoire Arbatel to live out a School-themed Romantic Comedy in Grimoire High School including Kimihito and his homestay girls with the exception of Lala. Later in Chapter 80, all of the people who were absorbed by Arbatel were released and returned to the normal world.

Trivia

 * While there were both male and female human students at the Grimoire High School, in return, there were apparently only female Liminal students. This is another indication of the fact that there are only a few male Liminals participating in the Interspecies Cultural Exchange Program, which once again calls into question the equality between female and male Liminals from the Japanese government.
 * As revealed in Chapter 76, the school uniforms where the reason why everyone whose consciousness was absorbed by Arbatel thought they were students at the school. The brainwashing could only be broken when a "student" took off their uniform, but nobody did that (except Papi) since the students kept their uniforms on even while sleeping (probably due to Arbatel's magic).
 * Kimihito was the only "student" who was never brainwashed despite wearing a school uniform the whole time. This was because, as Arbatel revealed to him in Chapter 80, she had intentionally left him sane because she saw him as a "harem rom-com protagonist" (because he lives together with seven Liminal girls), and hoped that the Grimoire world would change his "filthy harem obsessed heart".
 * As Manako and Tio revealed in Chapter 80, after Arbatel released the consciousness of all the absorbed people, basically each of them had decided not to blame Arbatel and even praised her because they had all started new relationships through Arbatel's input. A few also thought that Arbatel just went a little crazy, but ultimately the Liminal laws were not clear in this particular case, so Arbatel was not held accountable for her actions, although Kimihito and Centorea were skeptical about it.
