Aya Mikage and her twin brother Aki go to their grandfather's home for their sixteenth birthday unaware that it's actually a test to see if they have enough angel or celestial maiden blood in them. Aya is the reincarnation of a supremely powerful celestial maiden called Ceres. When she transforms into Ceres, Aya obtains many supernatural abilities such as flight, teleportation, telepathy, incredibly strong and powerful telekinesis, premonition, projecting powerful and destructive deep pink glowing energy blasts from her hands, creating incredibly strong and powerful impenetrable shields and barriers of pure deep pink energy, and superhuman speed. According to the legend, Ceres will kill the entire Mikage family for revenge upon stealing her hagoromo/celestial robe, thus preventing her returning home to Heaven, so Aya's family attempts to kill her. However, she is saved by Suzumi Aogiri, another tennyo descendant with supernatural powers, (since not all Mikages have angel blood) and Suzumi's brother-in-law, Yūhi. Aya tries to control Ceres' power and hold over her and Aki is eventually completely taken over by the vengeful and hateful spirit and soul of "Mikagi", the original ancestor of the Mikage family who first stole Ceres' celestial robe, forcing her to stay on Earth. Aya also wrestles with her growing and deep romance love for Toya, a servant of the Mikage who is trying to kill her, but lost his memory of his past. However, he begins to fall deeply in love with Aya, who grows to reciprocate his feelings, and they conceive a child together. Aya promises Ceres to help her find her celestial robe in exchange for not killing her family (especially Aki) who hunts her down, since Aya still loves them. Toya tries to regain his memory, and he learns that he was the immortal living humanoid organism that Ceres' celestial robe (otherwise known as "the mana") created to help it reunite and become one with Ceres. At the end, Aki, having not fully succumbed to Mikage, sacrifices himself to save Aya, and Toya sacrifices his mana to save Aya and their unborn child. Months later, Aya and Toya await the birth of their child, although they know that Toya has limited time left with her.
