Aigen, formerly Solar Sands is a town located in Ward 5.
Aigen was founded in January 2, 2022 as Solar Sands, which is named after the YouTuber of the same name. In October 21, 2022, it was renamed to its current name, Aigen (Japanese: 藍原市 Aigen-shi) to reflect chimata's intention to revive the project and to see if AI generators can guide and assist the mayor's in building things.
Aigen was almost chosen as a candidate for Formula MRT season 4 back when it had no development at all.
