Eden: It's an Endless World! is a manga by Hiroki Endo, published monthly in the Japanese magazine Afternoon. It is published in the United States by Dark Horse Comics, in the United Kingdom by Titan Books, and in Germany by Egmont Manga & Anime. Eden is set in the near future, following a pandemic called closure virus which killed 15 percent of the world's population, crippled or disfigured many more, and upset the world's political balance greatly. Eden is to some extent based on Gnostic mythology, with some characters, such as Ennoia, being named after Gnostic entities, and other Gnostic influences being seen in the themes of the ongoing story.
