Amaterasu, who became the deity ruling Nenokuni, governed Nenokuni with Hikaru, who chose to remain with her. One day, just as a mirror entered Amaterasu's sight, a large earthquake struck. Although Amaterasu was unharmed, her beloved Hikaru disappeared. Amidst a plethora of unknowns—who did this, what happened— Amaterasu, sensing Hikaru's presence in the distance, began to act to get Hikaru back.
