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…

Follows the heroines from the Aincrad arc through their various adventures in the real world at the SAO Survivor School and in the virtual world of ALfheim Online.

In the year 2022, gamers rejoice as Sword Art Online—a VRMMORPG (Virtual Reality Massively Multiplayer Online Role Playing Game) like no other—opens its virtual doors, allowing players to take full advantage of the ultimate in gaming technology: NerveGear, a system that allows users to completely immerse themselves in the game world by manipulating their brain waves to create a wholly realistic gaming experience. But when the game goes live, the elation of the players quickly turns to horror as they discover that, for all its amazing features, SAO is missing one of the most basic functions of any MMORPG—a log-out button. Now trapped in the virtual world of Aincrad, their bodies held captive by NerveGear in the real world, users are issued a chilling ultimatum: conquer all one hundred floors of Aincrad to regain your freedom. But in the warped world of SAO, "game over" means certain death-both virtual and real…

The setting for the third story arc. It is a virtual game world with a main focus on guns, although melee weapons like lightsabers and knives also exist. From all the games it is the most competitive one as the money earned there can be exchanged for currency used in the real world, drawing high-tier professional players to make a living from it.

Project Alicization, a top-secret government project run by Rath, a company affiliated with the Japan Self Defense Force (JSDF), was started to create the first highly adaptive, «Bottom-up AI». By using a 4th generation FullDive machine, called the Soul Translator (STL), Rath succeeded in copying the Fluctlights (souls) of twelve newborn babies, creating a «Soul Archetype», a non-developed Artificial Fluctlight that could be copied to create new Artificial Fluctlights, which would then need to be nurtured to mature into an individual. For this reason, a virtual world, codenamed «Underworld», was created using the free kernel version of the Cardinal System, The Seed, and then transferred into the STL mainframe via the Mnemonic Visuals feature of the STL. Underworld is set in a past era, when science and philosophy were just being discovered, but instead of recreating a past era, limited terrain and certain customs were introduced so that the inhabitants of the world would form their own society.
