这是超越维度的游戏。
亦是追寻真理的竞逐。
未知的封印，鬼神的赌局……
数据的抗争，人类的救赎……
在那个连接着现实的虚拟世界——意识决定我们，意识选择我们，意识决定了我们的意识。
现在，丢掉你的恐惧。
丢掉你的私心杂念、疑问和拒信……解放你的思想。
欢迎来到，惊悚乐园。

When the creator of a popular video game system dies, a virtual contest is created to compete for his fortune.

In the year 2022, a massive online role-playing game called Sword Art Online (SAO) is launched. With the aid of "NerveGear" technology, players can control their avatars within the game using nothing but their own thoughts.

Kazuto Kirigaya is among the lucky few who get their hands on the first shipment. He logs in to find himself, with ten-thousand others, in the scenic and elaborate world of Aincrad. However, in a cruel turn of events, the players soon realize they cannot log out; the game's creator has trapped them in his new world until they complete all one hundred levels of the game.

In order to escape Aincrad, Kirito will now have to interact and cooperate with his fellow players. Some are allies, while others are foes. Sword Art Online is not all fun and games: if they die in Aincrad, they die in real life. Kirito must adapt to his new reality, fight for his survival, and hopefully break free from his virtual hell.

A year after escaping Sword Art Online, Kazuto Kirigaya has been settling back into the real world. However, his peace is short-lived as a new incident occurs in a game called Gun Gale Online, where a player by the name of Death Gun appears to be killing people in the real world by shooting them in-game. Approached by officials to assist in investigating the murders, Kazuto assumes his persona of Kirito once again and logs into Gun Gale Online, intent on stopping the killer.

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...

A special recap of the first season with an original story in which Kirito and the others decide to go on an underwater mission so that Yui can see a whale, but they face a shocking revelation... Suguha is afraid of water. So Asuna and the other girls decide to teach Suguha how to swim. Meanwhile, Kirito is meeting somebody.
