[Edit]Voiced by: Akiko Yajima (Japanese), Meredith Taylor-Parry (English)
Aya's distant cousin and a C-Genomer from Shizuoka Prefecture. She is an ordinary, high-school girl living a normal, happy life with her mother. Her mother was summoned by the Mikages and was killed at the main house when Aya first transformed into Ceres. When Aya comes to a new school, the two meet and become friends. Although Aya doesn't know about her personally, Miori is only pretending and has an agenda of her own. She transformed into a tennyo to take on on Aya (as Ceres) to avenge her mother's death. She later committed suicide as her final act of "revenge" against Aya. Miori is identified by the Mikage scientists as possessing the same tennyo type as Aya.
