Ceres (セレス Seresu?) is a celestial maiden or tennyo from the legend, who married the founder of the Mikage family, Mikagi Mikage. While she is immensely strong and powerful, and volatile, she seeks to recover her hagoromo, or celestial robe, to regain her true form, and full powers and abilities. She has repeatedly attempted to manifest herself through certain female descendants of her bloodline when they reach the age of sixteen, only to be thwarted each time as they are relentlessly killed by the Mikage family. Ceres hides a tragic past misinterpreted by descendants who seek to kill Aya to prevent Ceres from manifesting through another generation.
