Lost Universe

is a series of science fiction light novels, running from 1992 to 2000, by Japanese author Hajime Kanzaka. It was later adapted into an anime that ran throughout the summer of 1998 on TV Tokyo during the time slot that the anime depiction of Kanzaka's previous work, Slayers, ran, spanning a total of 26 episodes.

Plot
Kane Blueriver, a trouble contractor, is being hunted by a criminal syndicate named Nightmare because he pilots the Lost Ship Swordbreaker, the only hinderance to Nightmare's plan to spread the dark lord Dark Star throughout the galaxy. Kane, along with Millie, a girl who dreams to be the "best in the universe," and Canal, Swordbreaker's AI, vows to defeat Nightmare, who, besides having a sinister plan, killed Kane's grandmother many years ago.

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", intelligent space ships of unknown origin that have powerful or somewhat divine powers with more advanced technology than any other device in the universe. Their rarity and superiority has sparked suggestions that they have been made by an advanced ancient alien civilization or by coming from the beginning of the universe itself. Being a central part to the plot the "Lost Ships" are intelligent beings with different loyalties and even their own agenda. 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.
