The Elysium. A private, completely self-maintained cruise floating in space, welcoming specific people with its invites. Shiria, a simple but nice girl, woke up aboard the Elyisum with no memories. Her invite untraceable despite her presence. Ten other passengers, everyone with their own ideas, vocations and struggles. Some are kind, some are jerks, some are plainly mysterious. Among the Elysium's great source of entertainment and respite, "death" looms above. What is "death"? Who is Shiria?
