Ashinaka High School

is a large educational institute that stretches across an entire island just off the coast of Tokyo Metropolis, not that far away from Shizume City.

Localization
The school is located on a remote island off the coast of Tokyo Metropolis, accessible only by a unique train system, in which a series of trains transport people from the mainland to the island directly beneath a large bridge. Transportation is only open to students using PDA's and lacking one results in the inability to enter or exit the island.

Uniform
The girls' uniform consists of a black, long-sleeved sailor fuku that is tied at the back by a bow and has a maroon ribbon that sits over the chest, a maroon skirt that parts at the back and has white ruffles underneath, and brown bar shoes. However, girls make minor alterations with their uniforms, such as the shoes they wear or replacing the maroon ribbon with something like a bow.

The boys uniform consists of of a black, high-collar jacket, a long-sleeved white shirt, black pants, and either brown or black shoes. The most common addition to the uniform is either a red tie or bow tie, however ribbons are also worn.

Many students also wear a golden, oval-shaped pin on their shirt that signifies that they are a student of Ashinaka High School.
