One month has passed since the death game known as Sword Art Online began. 2,000 players have already died and no one has cleared the first floor of the game. Kirito and Asuna are two players who desire to fight alone but with their first meeting, they get drawn to each other. The two individuals soon realize that they must work together in order to survive the deadly world of Aincrad.
Sword Art Online: Progressive is a retelling of the Aincrad Arc in the original series. Instead of skipping two years after the death game began, this volume takes place on the first and second levels of Sword Art Online. Now that the story of the Aincrad Arc was set in stone, knowing how it eventually ends, this retelling focuses more on the events, characters, the world, on each floor.
