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.

Silca is known as Dragon Tamer Silca, but after leaving her group she is caught and her pet, Pina paid the ultimate price. Before she is killed, Kirito saves her and offers her a choice.

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

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

A trip to get a new sword leaves Kirito battling a dragon and his fears.

After 2 years, people have got used to living in SAO, with a dwindling front line it might just be up to Kirito and Asuna to continue the charge.

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

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…

The newly married couple is enjoying their time away from the front lines. But a new guest will take them all the way back to the beginning.

Yulier, second in command, of the Liberation Army has approached Kirito and Asuna for help saving her friend and her guild.

While enjoying a fishing tournment Kirito receieves an urgent e-mail from the leader of the guild requesting their return.

Game over.

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

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

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.

Something isn’t right; Recon has sent Leafa a message “I was right. Be careful. S." What does he mean and will Leafa and Kirito have the time to figure it out?

Kirito and Leafa have made it to the meeting and Kirito’s bluff as an ambassador has been called out. If he can survive in a fight against the Salamanders General Eugene, his plan to prevent a 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 the insane. His reckless is stopped when Leafa suddenly logs out.

Even though a wall has been built between Kirito and Sugu, he must 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.

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