Amane is one of the four Handmaidens, appointed to serve in the Kuze Shrine. She served under and cared for Reika, the woman who was to be the Tattooed Priestess. Amane is the only one of the Pacifiers who was an actual member of the Kuze Family, and was also the first to be chosen.
She was the daughter of Kyouka and the half-sister of Kaname, Reika’s lover. Kyouka had an affectionate relationship with a visiting folklorist named Akito Kashiwagi. This produced a forbidden son, Kaname, so Kyouka sent the child away to a nearby village. Shortly before this, Akito disappeared. A few years later, another man was brought to Kyouka and this time she bore a daughter by him, who was Amane.
