Souya Kuroi's life is complicated by the fact that his only memory is a nightmare involving a massive dragon destroying everything in a blaze of rainbow colored light. After being told that he lost his parents and memory in a strange accident, he's taken care of by his guardians, the spunky maid Ginko and the enigmatic cat Sensei. When a teddy bear-shaped UFO invades Saromisaka City, seven mysterious people emerge to fight it off, displaying similar rainbow colored lights to Souya's dream. These "heroes" soon face a new challenge: Souya, who's determined to take revenge on the people who destroyed his old life.
