13th District

The 13th District is the area in which the participants are currently in. While the participants suspect that there are other "Districts" and games going on around them, it is revealed that the name of the district is changed every game, indicating that it is currently the 13th time that games are being streamed on the Genome Island.

History
Originally, the island was supposedly going to be a theme park, but was not able to be completed due to funding issues. The island was later sold, along with its constructed buildings and activities. Shortly after, the island was bought by Akatsuki's father, and the island was transformed into an experimental site.
