A series of 4-panel comic strips that touch on the days of Aincrad in a comedic viewpoint.

The year is 2022. Mankind has finally perfected virtual reality. And within the VRMMORPG (Virtual Reality Massively Multiplayer Online Role Playing Game) Sword Art Online, there was a player called Kirito. While he was enjoying the world of SAO, he and the other 10,000 logged-in players all received a frightening message from the Game Master—that the only way to escape from that world was to clear the game, and that a game over within the game would mean their death in the real world.
That was the frightening true story behind this game.
Kirito was one of the first players to accept this “truth”, and began his solo play, refusing to form a party, as he threw himself into the never ending battles that lay before him…

In 2026, four years after the infamous Sword Art Online incident, a revolutionary new form of technology has emerged: the Augma, a device that utilizes an Augmented Reality system. Unlike the Virtual Reality of the NerveGear and the Amusphere, it is perfectly safe and allows players to use it while they are conscious, creating an instant hit on the market. The most popular application for the Augma is the game Ordinal Scale, which immerses players in a fantasy role-playing game with player rankings and rewards.

Following the new craze, Kirito's friends dive into the game, and despite his reservations about the system, Kirito eventually joins them. While at first it appears to be just fun and games, they soon find out that the game is not all that it seems...
