Chapter Summary: In Slayers, it was mentioned that the main characters of that series live on a world that is one of the four created by the mother of all creation, called The Lord of Nightmares or simply LoN. This world was known as the Red World. Lost Universe, however, takes place in a different world, known as the Black World. Whereas the demi-gods of the various worlds such as Ruby-Eye Shabranigdo and Dark Star Dugradigdo had physical presence in that world, they appear in the Black World as "Lost Ships," or space ships that have mystical or somewhat magical powers. Kane Blueriver, a "trouble contractor," inherits a "Lost Ship" from his grandmother and from there, he and his sidekick Milly, together with Canal, the ship's computer, journey to find a source of the evil that threatens the universe. That evil results to be Nightmare company.
