A modern fantasy rooted in Japanese Shinto legends. Suzuhara Izumiko is a 15-year-old girl who has been raised and protected in a shrine deep within the Kumano mountains. She is quite shy and destroys every electronic device she touches. When she begins to consider leaving the mountains to move to the city, her guardian Sagara Yukimasa recommends that she attend a high school in Tokyo and forces his son, Miyuki, to serve Izumiko for life. Miyuki and Izumiko initially repel each other, but their relationship begins to change after a terrifying accident occurs during a school excursion. Izumiko learns of her fate as the last representative (yorishiro) of a Himegami goddess, and Miyuki learns of his duty as a guardian Yamabushi to Izumiko.
