In a realm known as Earthside, alongside Nosfertia, Heavenstia, and Eternalia, a threat emerges as Darknoids from Nosfertia launch an invasion. To thwart this peril, Heavenstia dispatches three Animanoids to safeguard Earthside. Among them is Touya, who uncovers his true identity as a denizen of Eternalia, not merely a human. Empowered by this revelation and aided by the trio of Animanoids, Touya valiantly battles to protect Earthside from the encroaching forces.
