SoltyRei (ソルティレイ Sorutirei) is a Japanese anime series by GONZO and AIC combining attributes of drama and sci-fi, about the inhabitants of a city where an Aurora prevents aerial travel. It is directed by Yoshimasa Hiraike and co-produced by TV Asahi, GONZO and AIC with music by Toshiyuki Omori.

On 2006-04-02 FUNimation Entertainment confirmed at Anime Expo that it had the rights to distribute Solty Rei. Prior to this, a fansubbing group had reported receiving a cease and desist letter from FUNimation Entertainment with the English name of the anime given as Origin, although the name seems to have been confused with Origin: Spirits of the Past.

Roy Revant is living the hard life of a bounty hunter in a broken city, a city where thousands have died in mysterious event called the Blast Fall. Those who survived share the sting of loss. Countless Resembles walk the streets, people whose mangled bodies have been rebuilt with high-tech prosthetic devices.

Yet there are those that even science cannot mend. Roy needs a miracle to escape his rut... and one night she falls from the sky. Like countless others, Solty is a Resemble, but one unlike the world has ever known. A young girl without a past, soon she will have a family. But in this world, pain and alienation are never too far away.
