In the near future, a virtual reality game called Sword Art Online has been released where players control their avatars with their bodies. One day players discover they cannot log out, as the game creator is holding them captive unless they defeat the final boss. However, if they die in the game, they die in real life. Their struggle for survival starts now.

It's been one month since the players' entrapment in the game. Nearly 2000 people have died and the first floor hasn't been cleared yet.

Kirito faces the consequences after witnessing the deaths of some of his friends in reality.

Dragon Tamer Silca leaves her group and pays the ultimate price. But before she is killed, Kirito offers her a choice that could have saved her life.

A player has been killed inside a safe zone and not by one of the known means. Asuna and Krito take it upon themselves to find out how and why this happened.

After much investigating, Kirito figured out how players are dying in the safe zone and now he has to figure out why. Unfortunately danger is just around the corner.

Kirito seeks the help of Asuna's friend, Lisbeth, to craft a custom made sword.

Kirito begins a rivalry with Asuna's bodyguard, who is also a member of the Knights of the Blood Oath.

To save a group of players, including Asuna, from a boss character, Kirito is forced to play his trump card.

Kirito duels the leader of the Knights of the Blood Oath in exchange for Asuna's freedom.

A newly married couple is enjoying their time away from the frontlines. Unfortunately, a new guest will take them all the way back to the beginning.

Yulier is second-in-command of the Liberation Army and has approached Kirito and Asuna for help. She needs to save her friend and her guild.

Kirito and Asuna's vacation is cut short when Heathcliff requests their return.

It's game over. Kirito and Asuna spend their last moments together. Will they find one another again?

Kirigaya is adjusting to his life outside of the game, but he hasn't forgotten about Asuna. During a recent visit to the hospital he meets Sugou Nobuyuki.

A new MMO allows users to fly and encourages player killing. Kirito has joined this new game in search of Asuna and is pleasantly surprised with what he finds.

As Kirito learns about the game and the hatred between the races from Leafa, Asuna learns the truth of her role from the Fairy King.

Leafa is making enemies when she leaves her area to team up with Kirito. On their way to neutral territory rules and areas are discussed.

Leafa realizes something isn't right when recon sends an ominous message. What does it mean and will Leafa and Kirito have time to figure it out?

Kirito poses as an ambassador during a major meeting. If he can survive a fight against the Salamanders' General Eugene, his plan to prevent war might work.

While Asuna continues her attempt to escape, another woman in Kirito's life tries to make sense of her emotions.

Kirito's determination to save Asuna borders on sloppy and insane. His recklessness is stopped when Leafa suddenly logs out.

Even though a wall has been built between Kirito and Sugu he is determined to save Asuna. The next time he challenges the final dungeon he won't be alone.

Kirito, Asuna, and Yui are finally together again, but the locks placed on Asuna are unbreakable. Before they have a chance to come up with a plan, the Fairy King makes his grand entrance.

Kazuto has beaten death twice, but there's one more thing he must do before he can see Asuna in the real world.
