神楽黎明記～ましろの章～

A request for exorcism arrives at the Kirinomori Shrine.
The young exorcist miko, Mashiro Saeki, sets out to meet the client in a nearby town.

There, she learns from the local priest and his wife that yokai have begun to appear around the area, and the townspeople may soon be forced to abandon their homes.
While searching through old family records, the couple discover that, long ago, a powerful yokai had been sealed deep within the nearby mountain.
