School District 18

One of the larger school districts, it is a district where top schools in ability development are located.

Principles
It is contains prestigious schools such as Nagatenjouki Academy and Kirigaoka Girls' Academy. It apparently uses a scholarship program that is separate from the one that is used in the rest of the city.

The district's structured in a logical manner, however, one gets the feeling that the life there is thin, where the widths of the roads are uniform, and the architecture is designed for the people to not stray from the rules. When Shirai Kuroko was investigating Grim Reaper Kakiko, she criticizes the district as a prison for children but a paradise for adults.
