The map of Four Islands Archipelago as seen in Episode 1 of the anime.

The Four Islands Archipelago is comprised of four larger islands known as Fukurujima, Kunashima, Kasamajima, and Kamidoorijima. In addition, there are around 30 smaller islands crowded in the area. While there used to be many unoccupied islands in the past, the advent of anti-gravity shoes has allowed flight in the sky, effectively increasing the number of inhabitants as a result.


  • Kunashima
  • Fukurujima
  • Kasamajima
  • Kamidoormaijima



Kunaashima is the island where most of the main characters live. The new areas of town where commercial institutions and citizens live are separated from the old district. Although the population is increasing, it is still mostly rural. Masaya, Asuka, Misaki, and Mashiro all attend the same academy here.

Known Things on Kunashima

  • Kunahama Academy

Kunahama Academy rests on top of a hill, where facilities for Grav Shoes have recently been established. However, Flying Circus clubs are not the only facilities located at the schools around the islands. Some special additions have been established at the building, including a rooftop garden for students to relax.

  • Club Room from the inside

Originally, the main characters used a run-down bus as their base of operations. Now however, they’ve installed everything from radios to outlets for electrical devices, creating an atmosphere that’s more suitable for passing time.
