Grimoire High School

Grimoire High School is a extra-planar location set inside the Grimoire Arbatel.

A location set entirely inside a book, Grimoire High School appears as a typical Japanese high school containing a population of both humans and extraspecies living together harmoniously.

Layout
The layout of Grimoire High School consists of the school, a park, a mall, a 7/11 convenience store and the school dormitories. Nothing else exists beyond these locations and if a student attempts to venture beyond the location borders they will simply find themselves magically heading towards one of the existing locations instead (eg Papi attempts to fly back home only to repeatedly end up flying to the school dormitories instead).

Dormitories
The Grimoire High School Dormitories are a block of multi-level residential complex buildings intended for use as living quarters for the school's students. The buildings are separated by gender (with one building intended for use by male students and another building intended for use by female students), however both genders can enter and loiter within either building freely. Each student's residential quarters consists of a small living apartment with a bed and bath. It is unknown whether each quarters also has private cooking facilities or if that is located in another part of the building.

School
The Grimoire High School school compound is where the school's main building and teaching facilities are located. The school possesses the typical facilities of a modern Japanese high school; with class rooms, physical education facilities and cafeteria.

7-Eleven
A 7-Eleven Convenience Store located across the road of the main school compound's entrance gates.

Park
A small park near the school with paved paths, trees and a large pond in the middle. The pond is also used by the school for swimming lessons, which take place daily from 9am-to 6pm. But the most students simply visit the park in their free time to relax.

Trivia

 * A common trope in "school-life genre" anime and games is the trope of students running to get to school before the school day starts and they close the gates. The trope is usually a source of comedy, as the students do various things in their attempt to pass through the gate before they close (or, failing that, jump the fence).
 * As is typical of a Japanese school, Grimoire High School has its own set of school-based urban legends known as "The Five Mysteries of Grimoire High School" (Although school-based urban legends usually number up to seven in other schools).
 * As revealed in Chapter 76, the school uniforms were 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 because of Arbatel's magic).
