Millennium Feria Nocturne, often called Millie, is a central character in the science fiction series Lost Universe. She is the granddaughter of Albert von Stargazer, the head of the criminal organization known as the Nightmare Syndicate, but she adamantly opposes him and rejects that heritage, even changing her surname to Nocturne from her birth name of Stargazer. Millie's background begins as an ambitious private detective who, during a mission involving the criminal Dugall Connection, becomes entangled in an incident with Kain Blueriver. This event gets her fired from her detective agency, but it leads her to join Kain as a partner and occasional assistant on his spacefaring adventures aboard the Lost Ship Swordbreaker. Her primary motivation is the overarching, almost catchphrase-like goal to be the best in the universe at absolutely everything she tries, a drive that fuels her pursuit of many ventures including investigation, marksmanship, bounty hunting, and even beauty pageants. In terms of personality, she is happy-go-lucky, lively, and often serves as a comedic foil to the more stoic Kain. She is loud, emotional, and energetic, creating a strong contrast with her partner. Her role in the story is that of Kain's sidekick and a member of the crew, often providing comic relief and acting as a proxy for the audience as she discovers the wider universe and Kain's past. Her key relationships include a close but bickering partnership with Kain Blueriver, a friendly dynamic with the ship's AI hologram Canal, and a deeply conflicted connection to her villainous grandfather, which she only fully learns about late in the narrative. Over the course of the series, Millie develops from a clumsy and sometimes inept amateur into a more integral member of the team, though her moments of emotional depth surface when confronting her family secrets and her feelings of responsibility. Her notable abilities are highly contradictory: she is a expert sharpshooter and a proficient cook, yet her cooking almost always results in massive explosions that destroy the kitchen. She also demonstrates competence as a private investigator and a capable fighter, despite her frequent failures in other endeavors.
