Amelia ran a clinic with her brother Frank in a small village, Isengrim, adjacent to an eerie forest . One day Amelia meets Wolff , who was injured in the village . He was the forest guard who came to monitor the forest. Ever since she met Wolf, Amelia encounters something strange, such as a mysterious flame or a terrifying monster.

In the meantime, Amelia is fascinated by his mysterious charm when she sees Wolff, who sometimes resolutely protects the village, though seemingly dull and unreliable.
