Long ago there was a battle between angels and humans, which ultimately ended with the angels’ retreat. Twelve thousand years later, the angels have become active again and have begun harvesting humans for nefarious purposes; and only the pilots of the ancient mecha known as Aquarion are able to oppose the angels' tools of war. The pilots have special powers, but the secret to defeating the Angels once and for all lies with the reincarnations of the two beings who defended humanity against the Angels in the past: Apollonius, an Angel who turned his back on his kind in order to protect humanity; and Siren, his human lover. Only Apollonius can awaken the true strength within Aquarion that is needed to defeat the angels; but who is the reincarnation of Apollonius?
