The mystery, which he wants to solve most of all in the world, is the tragic disappearance of his mother. But it is not easy ... especially in this world, where everything does not seem like. Cats say blood-sucking vampires roaming around the ground, and monsters eat such guys like Kouhei for breakfast. Can Kouhei survive this chaos long enough to find a mother he lost?
