Kamiarizuki no Kodomo Child of Kamiari Month
The story centers on a girl named Kanna who loses her love of running after her mother passes away. Due to the workings of the gods, she heads to Izumo City. The anime's setting is Izumo City in Shimane Prefecture, and centers on Izumo Shrine and the Kamiari myth in the region. In the old Japanese calendar, the month of October is called "Kannazuki" ("the month of no gods"). But in Izumo, it is called "Kamiarizuki" ("the month of gods") due to a legend that the myriad gods of Japan gather at Izumo Shrine during October. Other anime such as Kamichu! also portray this traditional belief.
