Ceres is a tennyo: a heavenly being maiden or celestial being who holds all th special powers that go with being a being from the heavens. Ceres holds a major grudge against the man who stole her hagaromo(cloak)ages ago. She's pissed to say the least. So mush that she keeps appearing in the consciousness of her decendent(Aya) so she can get her revenge and her hagaromo back. As a celestial being, she feels superior to humans, of course especially to men.
