(Modify later) With the gemstone exports and high-end tourism, it's imaginable that Zone 019 should be a relatively prosperous district. Some of the photos on Beneath the Dimension also reflect this, meaning it's a place very friendly to the wealthy.
As for the station, Green Sunshine is actually a realistic description. It's said that in some areas of Zone 019, due to geological activities, many cracked ravines exist. Some evolved unique species underground release special substances, which ascend into the sky with the airflow and form a thin membrane at a sufficiently high altitude. When sunlight passes through this membrane, a magical optical phenomenon occurs, turning the sunlight green.
This is the origin of the station's name.
Relying on this Green Sunshine, the area around the station gradually evolved into a tourist city, attracting countless visitors every year.
