Totally unexpected volume. I thought the story was done with Vol. 3 until I happened to see this one on the shelf at the bookstore. There seemed to be a lot going on with this one--Haseo's unrequited love, Atoli's unrequited love, CC Corp taking over the G.U. Project, Ovan being "alive" somewhere, and a plan to revive Aura. It was a little hard to keep track of, and I was confused at some parts. But the .hack story is wonderful as always! (July 2009)
