"Sword Art Online is one of the biggest series in the Anime fandom today. It is an animated adaptation of the light novel series by the same name which follows the adventures of a player named Kirito in various online games. In this first volume of Sword Art Online, we focus on the first two novels, which in this adaptation, is the first two episodes (a few chapters in the first novel) and then a majority of the side-stories from the second. While Sword Art Online may be incredibly popular in the Anime community, it may not be for everyone." - Attack On Gaming
