Marin Reigan lost his father and his home when Gattler staged a coup, forcing their people to abandon their dying planet and invade another. Seeking vengeance, Marin pursued. But when he saw the world they planned to invade, Marin found a new mission: to protect the untarnished skies and seas of that blue planet--Earth!

The battle will not be easy. Marin's technology is the only thing that can stand against Gattler's forces. But the Earthlings are not quick to trust him, and the ruthless enemy commander Aphrodia is hungry for vengeance of her own. Can Marin gain the Earthlings' trust, avenge his father, and stop the war?

Note: Originally planned and scripted for 39 episodes, the series was cancelled with various reasons cited including lack of anime magazine coverage and constant airtime changes. The 31st and last episode to air was actually produced as episode 32. Three unaired completed episodes (31, 33, 34) were later released on LaserDisc/DVD/Blu-ray, and the finished scripts and storyboards for the final 5 episodes had been shared in various magazines and a deluxe book.
