Long ago, a species called the Shadow Angels invaded Earth with the aim of draining every life force from its inhabitants. They arrived in a fleet of dark vessels, each bearing an aura that could siphon vitality from any living being. Their presence was felt across continents as the sky darkened and crops withered. By a miraculous turn of events, they fell into dormancy, granting humanity an additional 12,000 years of peace. Yet eleven years after a disaster known as the Holy Genesis devastated the planet, the Shadow Angels awoke from their sleep and launched new assaults. To offer humanity a fighting chance, an agency named DEAVA was established, and the deployment of a mech called Aquarion was approved. For Aquarion to reach its full potential, three pilots must fuse their hearts, bodies and spirits into a single entity—a task only a few can achieve. Consequently, the hunt for so‑called "Element Users" became top priority to secure humanity"s survival. Sousei no Aquarion chronicles Apollo, a nearly feral youth raised in destitution who is thought to be the reincarnation of a legendary savior. After his closest companion is seized by the Shadow Angels, Apollo decides to become an Aquarion pilot. Will he succeed in turning the tide of battle and liberating humanity from the Shadow Angels once and for all?
