Heroes: Battle Disk Densetsu

A galaxy near the center of the universe contains Planet Aernia and Planet Orbs, the latter inhabited by robots and ruled by Orbiton. Planet Aernia consists of several countries, including the volcanic Volculm, the oceanic Zylan, the forested Elvan, and the cloud-based Aleum, all under the central authority of Antania. Antania operates an academy dedicated to training Heroes, individuals with the ability to wield battle discs and serve as defenders of justice. The Governor General leads the country's efforts to cultivate these Heroes as a means of protecting Planet Aernia from the threat of Dark Desire.
