Five hundred years ago, the alliance of the three races, Fairy, Humans, and Beasts successfully vanquished Lord Volderius and liberated the Galactic Chaos from the domination of the demons. Following the vital victory, the galactic throne was left vacant, waiting for a new king to claim it. As centuries have gone by, the alliance between the ancient races has been broken off and the Galaxy falls into a whirlpool of wars for the throne. Once again, the demonic legion reemerges and forges an alliance with the monsters of darkness, waging war against the entire Galaxy.
