Ceres: Celestial Legend

Aya Mikage and her twin brother Aki are torn apart by an unexpected twist of fate. On their sixteenth birthday, they return to their family home for what seems like a celebration, only to discover it’s actually a test-one Aya doesn’t pass. She learns she carries the spirit of an immortal celestial maiden, a "tennyo," whose sole purpose is to reclaim her lost heavenly robe, the "hagoromo," and wipe out the Mikage bloodline. Suddenly, Aya is ripped away from her brother and forced to flee, pursued by the very family she once trusted.
