The setting for the fourth arc of the story. According to Kirito, it is graphically the most realistic of all VRMMOs to date. The flow of time in UW is much faster than the real world's (probably a prototype of the accelerated world). Even so, it seems that even Kirito was misled as to the actual rate of UW's time flow, so it is still unknown. However, in the "There is but one ultimate way" side story, the rate is said to be 10000 times faster than that of the real world.
