The entire island was like a country that could operate on its own.
The island even had their own farms, factories, and other places that were needed to sustain the residents.
The students lived in the dorm of their specific school, but the parents or relatives of the students had to live in the central city.
"The central city has an airport that students can use to leave the island or accept newcomers. Any other places are forbidden for planes or any kinds of flying-type vehicles to land."
The central city was the most bustling place on the entire island.
Elton Island itself could be said to be as big as Pandora Island and it was common for students in one specific school to use small vehicles to move from one building to another building.
Especially the junior high school, the senior high school and the college area.
These three areas were the largest and they didn't lose against the central city either.
