When the Shadow Angels invade after 12,000 years of slumber, humanity is held captive by fear and sheer alien dominance. Eleven years after the Great Catastrophe decimated the world, most of those left alive are scavengers, dirty and starving in the streets. There is hope, however: Mechanical Angel Aquarion! Through a swirling cloud of love, betrayal, loss and destiny, the last hope for the new century arrives and takes flight!

The real meaning of unity lies now exposed in two halves of the same heart, darkness and light that together make a whole. As the Shadow Angels and their wingless rivals rush toward their destiny, the secrets of the Solar Wing are revealed. This could mean either the end of the world or its redemption... One way or the other, the war ends now.
