Oneiromancy ideas claim that having dragon dreams symbolizes the struggle against giving in to your own rage. In a fitting coincidence, Souya Kuroi awakens from a nightmare in which a large dragon decimates everything in its path in a flash of rainbow-colored light. The waking world turns into a new nightmare for him after learning that he lost his parents and memory in a mysterious event. He is left with little choice but to be cared for by his two odd guardians, a large cat by the name of "Sensei" and a feisty and vivacious maid named Ginko. When a teddy bear-shaped UFO attacks Saromisaka City, his new existence is completely flipped upside down. Seven mystery figures emerge to battle the beast after military force is found to be ineffectual. The same rainbow-colored lights that Souya witnessed in his nightmare are used by these heroes to defeat the invader. These seven strangers are now up against Souya after the alien menace has been neutralized. He launches his battle against these "heroes," swearing vengeance on those who destroyed his former existence, and finds himself involved in a conflict of cosmic dimensions.
