Fifteen‑year‑old Izumiko Sudzuhara grew up in the Tamakura Shrine, which is located in the Kumano mountains. Her father worked in America, her mother in the capital; the shy and timid girl lived far from civilization under the care of her grandfather and grandmother. And it is no wonder that Izumiko had trouble with modern technology: computers behaved strangely around her, and everything else simply broke. The heroine, raised in the shrine, suspected that she could see far more than her peers, and only holy earth protected her from evil forces. How surprised she must have been when her parents unambiguously told her to continue her studies not in the familiar quiet, but in Tokyo at the Phoenix Castle Academy! Of course, Sudzuhara would not travel to a foreign city alone; she would go with the specially summoned Miyuki Saga, a sharp‑looking handsome man and an old acquaintance whose father is a mysterious mountain hermit. Unfortunately, no one told the youth the truth; as a result, the girl is only afraid, and the boy thinks she is foolish and cowardly. The truth is simple: Izumiko is the last of the "eryshiro" line, that is, a medium capable of containing the spirit of a kami goddess, and Miyuki is her chosen knight. Alas, such a vessel can host not only a benevolent goddess; therefore, young Saga will certainly have plenty of work in the capital. The heroine should take off her glasses and start working on self‑actualization.
