Gamarket is the setting for Hyperdevotion Noire: Goddess Black Heart. It is similar to Gamindustri as it four regions which contain the nations of Planeptune, Lastation, Lowee, and Leanbox; all which are ran by their respective goddesses, Neptune, Noire, Blanc, and Vert. However,the people of Gamarket represent games instead of game companies.
Gamarket is comprised of one large continent surrounded by four smaller island and other bits of land. In the farthermost western region there is Planeptune near the edge of the continent. Also in the western region, but a bit closer to the center is Latsation. On the far eastern region there is Lowee at the other edge of the continent while Leanbox is located just north of it on a nearby island. In the center of the entire continent is Arfoire's fortress.
The geographical makeup of Gamarket is mostly lush green grass, scattered forested areas, and various mountain ranges all throughout the main continent and its surrounding islands.
Gamarket is a play on the words "game" and "market."
