As a child, Amane's ultimate dream was to save her grandfather. A god named Shizuka granted her wish, under the condition that she would become his bride at sixteen. However, Amane's dreams were crushed as Shizuka cast a spell on her, turning her into a child. Shizuka's intense fixation on her still lingered, and he persisted in his desire to marry and consummate a relationship with her. On the other hand, Amane wished for Shizuka to break the curse and never cross her path again.
