A 3-volume, science-fiction light-novel series that is set in the past world of the Chrome Shelled Regios series. An anime adaptation was produced by Zexcs and aired from January 11th 2009 till June 20th 2009. It is licensed by Funimation Entertainment in North America.
In the anime Chrome Shelled Regios, the Legend of Regios side story takes place in the same world but during a time of the past. All of the characters speak in English with a Japanese accent, probably as a result of being voiced over by Japanese seiyu. It is also displayed in the form of an existing television show. Since the side story takes on very little time in the anime, not much of the story is fully explored with only few characters.
Plans for Investigations outside the Aurora Field begins, the area known as Insulated Space. Travelling detective Ailein Gafeit steps into it and meets Saya, a girl who resembles his lost sister, Nilfirya. Together they return to the Aurora Field. However, Ailein loses his memory. And for the sake of Saya's safety, they escaped the experiment facility and search for a safe haven where she can live. On their way, they encountered Erumi Riggzario, a member of the scientist team "Alchemist" and developer of the Aurora Field. Together with Erumi this time, they travelled through the Aurora Field.
Five years later, now an agent of Patrol Officer Dominio, Ailein while chasing after the genetic human Faceman, enters into the Insulated Space and transforms into a genetic human himself.
In order to solve the matter of genetic humans, an organization called Silent Majority is formed. In the midst of that, Ailein encounters Alchemist leader Ignatius and his lost sister Nilfirya. Dominio died in the hands of the duo and Saya was captured. In order to retrieve Saya and avenge Dominio, Ailein and Erumi ventured towards the capital city where Saya is taken.
