Ceres

Blood Type: O? Height: 166 cm. A celestial maiden or tennyo from the legend, who married the founder of the Mikage family, Mikagi Mikage. While she is extremely powerful and volatile, she seeks to recover her hagoromo, or celestial robe, to regain her powers. She has repeatedly attempted to manifest herself through certain female descendants of her line when they reach the age of sixteen, only to be thwarted each time as they are killed by the Mikage family. Ceres hides a tragic past misinterpreted by descendants who seek to kill Aya to stop Ceres for another generation. (Source: Wikipedia)
