.hack//Roots

This episode takes place after the G.U. game trilogy. The characters of both Roots and the "G.U." receive an email from Ovan requesting them to visit the festival held at a new Lost Ground, Hidden Forbidden Festival. There, they encounter many old friends, as well as an AIDA who appears to be non-hostile. At the end of the episode, Ovan is reunited with his sister Aina, who has been comatose since before the beginning of both Roots and G.U. This episode was shipped to people who had completed all three .Hack//G.U games as a reward and was thus not included in the original series. It was only made available to the japanese customers, and there are no foreseeable plans to bring "Returner" to other parts of the world.
