In this four-episode OVA, the control that human beings have over the world is in fact, an illusion; in reality, the vampires, werewolves, zombies, and other creatures that people think are mere myths are actually in possession of the real power. Each race is competitive, though, and is always trying to best the other groups and unseat them in the chain of control. This all changes when an ancient group of Aztec robots begins raining terror down on Earth, prompting the other once-warring creatures to temporarily join forces so that they can preserve the Earth they so love to fight over.
