It's launch day for one of the most highly-anticipated video games of all time. Join the character "Kirito" as he begins his journey in the virtual world of Sword Art Online.

It’s been one month since the players have been locked in the game. 2000 people have died; the first floor hasn’t been cleared yet.

Kirito has finally joined a guild made up of close friends in reality. Everything is going well until a tragic accident changes Kirito completely.

Kirito has figured out the how and now he has to figure out the why.

Kirito has agreed to a duel with the head of the Blood Alliance Knights. If Kirito wins, Asuna is free to leave the Knights and if he loses…

Game over.

Leafa is making enemies leaving her area and group to team up with Kirito. On their way to neutral Territory, they speak more of the rules and areas of the ALO.

Kirigaya Kazuto has beaten death twice but there is one more thing he must do.

Kirito and the others decide to go on an underwater quest to allow Yui to see a whale, but 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.

A year has passed since SAO was cleared. Summoned by Kikuoka of the Virtual Division at the Ministry of Internal Affairs and Communications, Kazuto learns of a series of bizarre murders linked to the popular VR game, Gun Gale Online (GGO), the only game in Japan played by pros.

Armed with a large sniper rifle, Hecate II, the young girl Sinon is making a name for herself as the No. 1 sniper in GGO. When her squadron ambushes another squadron, she succeeds in taking out her first target. But when she takes aim at her second target, a robed “Behemoth,” he dodges the bullet.

In real life, the player Sinon is a high school student named Shino Asada. On her way home from school, she’s dragged into an alley by delinquent girls. Their leader, Endo, tries to extort money from Shino, but she bravely refuses.

Kyouji attacks Shino, saying he'll kill himself after she's dead. Kazuto saves her at the last second by jumping Kyouji. During the fight, Kazuto is hit with Kyouji's poison syringe, but miraculously it doesn't work and Kirito is saved. The next day Kazuto and Shino go to meet Kikuoka, and discuss the incident. Kikuoka has a message from one of the captured Death Guns...

Kirito and the others are tasked with subjugating the Frost King Thrymr, and a quest to recover Excalibur. It's Yui's guess that this isn't a quest planned by the game admins, but something automatically generated by the system. And if that's the case…

Getting to experience the outside world, Yuuki’s days are more satisfactory than ever before. In ALO, the players have a barbecue and end up on a quest. In the real world, Asuna and the girls take a trip to Kyoto. One day, Asuna receives an email…
