It is set in a pre-apocalyptic universe: according to the manual and pre-game introduction, the giant red sun is about to go supernova within hours and representatives from each alien race must fight each other in order to gain the trust and service of an ultra-intelligent race known as the Primaries who will grant them and their future generations another galaxy to live in. There are only two humans in the game but they don't come from planet Earth. However, the game itself tells a different story of a demon lord who leads an underground campaign against a 12 star galaxy to take control of it. He conquers all of the stars' rulers and makes them his slaves except for one. Taking control of this lone hero, the player battles through the enslaved rulers and into the final battle with the demon lord, Lord Valgasu, himself.

Both the game's intro and ending reflect this storyline.
