.hack//G.U. Returner (2007)

A short OVA featuring characters from the .hack//G.U. games and the .hack//Roots anime. Each of the players receives a mysterious email from Ovan about a summer festival in Δ Delta Server.
It’s G.U's version of a meet and greet between different aspects of the .hack world and as such plays out exactly as you’d expect it would.
