On November 6, 2022, the new generation Virtual Reality Massively Multiplayer Game, Sword Art Online was finally released and 10,000 copies of the game were sold in the first batch. However, on the first day of its release, the creator of the game, Kayaba Akihiko, announced that the only way to log out of the game was to conquer the one hundred floors of the Floating Castle Aincrad by defeating the Floor Bosses at the top of the Labyrinth of each floor. However, if the players died in-game, the NerveGear used to play the game would fry their brains. The same would be done if someone from outside would attempt to remove the NerveGear by force. To prove how serious the game was, he transformed the avatars of each player to look as their real life bodies.By the time nearly a month since that faithful day had passed, about two thousand players had already died, while the 1st Floor's Labyrinth had yet to be cleared. On December 2, 2022, a solo player Asuna was ready to meet her demise at the hands of several Ruin Kobold Troopers, when another solo player, Kirito, intervened and saved her.
