The SAO incident, which trapped 10,000 people in a virtual reality game for several years, is in the past and the survivors are now moving on with their lives. Technology is advancing as well and a competitor to the Amusphere soon appears on the market, one which provides a similar experience using augmented reality. Marketed as being safer than the full-immersion required by VR, the Augma quickly amasses a large following… but as Kirito and his friends discover, this AR experience is far more dangerous than it appears.
An action-drama with a romance subplot that takes place after Sword Art Online II. While it provides a brief recap of previous events at the beginning, there isn’t much point in watching it if you haven’t at least seen Sword Art Online.
