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.

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.

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 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.

Kirito, along with his childhood friend, Eugeo, has been tasked with cutting down a colossal tree called the Gigas Cedar. They’re swinging their ax when their friend Alice arrives with lunch. As they eat, the three friends decide to go to a fabled cave.

Kirito wakes up to find himself inside a mysterious world evoking a fantasy game. His memory fuzzy, he tries to log out, but is unable to return to the real world. After wandering aimlessly, he finds himself underneath a colossal tree.

Kirito makes up his mind to journey to Centoria. Since he'll need Eugeo's help, he also decides to fell the Gigas Cedar. Meanwhile, Alice's little sister, Selka is worried about Eugeo, and opens up to Kirito about her concerns.

Kirito and Eugeo realize Selka has taken off to the End Mountains alone, and decide to chase after her. As they enter the cave, they encounter goblins, presumably from the Dark Territory, and must engage in a battle.

In the real world, Kazuto Kirigaya lies unconscious. At Kikuoka’s request, Kazuto is moved to a well-equipped hospital, but when Asuna and Suguha try to visit, they’re turned away. Suspicious, Asuna and the others split up to find out more about Rath.

Asuna infiltrates Rath, the research lab in the Ocean Turtle, where she relentlessly grills Kikuoka about Kazuto's whereabouts. Kikuoka reveals that behind the development of the Soul Translator is a mind-blowing objective of epic scale.

Two years have gone by since Kirito and Eugeo left Rulid Village. In the capital city, Centoria, both boys have attained their goal of being admitted to the North Centoria Imperial Swordcraft Academy.

Kirito finds himself in a duel against the Elite Disciple Volo Levantein, using real swords. As the curious crowd looks on, Kirito is encouraged by Sortiliena, and the duel begins.

Now an Elite Disciple along with Kirito, Eugeo struggles with the question of what he should infuse in his sword so he can become stronger. When he's taunted by First-Seat Elite Disciple Raios and Second-Seat Humbert, Eugeo decides to accept Humbert's request for a duel.

Ronie and Tiese are late getting to the dorm. Kirito rushes out in search of them, but no sooner has he gone than Frenica appears. She tells Eugeo about how she's suffered at Humbert's hands, and that Tiese and Ronie went to confront him about it.

Kirito and Eugeo are now considered criminals for having violated the Taboo Index and are thrown into the underground prison in the Central Cathedral. Meanwhile, on the Ocean Turtle in the real world, Asuna is watching over Kazuto as he's being treated.

Kirito and Eugeo escape from their cell, only to find their way blocked by Eldrie Synthesis Thirty-One, under orders from Alice to lie in wait for them. Kirito and Eugeo struggle against him until Eugeo realizes that he's seen Eldrie somewhere before.

Kirito and Eugeo have been rescued by the young girl, Cardinal, who has secluded herself inside the Central Cathedral’s Great Library. Cardinal explains to Kirito how the Axiom Church and the Taboo Index came to be, starting with Administrator’s past.

After being entrusted with the fate of the world by the Cardinal, Kirito and Eugeo head to the top floor of the Central Cathedral. On the way, they find their confiscated swords among a vast pile of weapons in an arsenal, only to be greeted with a hail of arrows by the Integrity Knight, Deusolbert Synthesis Seven.

Kirito and Eugeo are on their way up the stairs of the Central Cathedral when they encounter two girls named Linel and Fizel. As they stand, wondering what two children are doing there, they let their guard down and...

Though riddled with wounds, Kirito manages to activate his Perfect Weapon Control art. Continuing on their way to the top floor of the Central Cathedral, Kirito and Eugeo find themselves standing before a strange-looking floating platform.

When Kirito and Alice both unleash the Perfect Weapon Control art in the Cloudtop Garden, the impact rips a hole into the seemingly impregnable Central Cathedral wall, which sends them both flying outside.

Eugeo reaches the ninetieth floor of the Central Cathedral, which turns out to be a vast bathing area. The perplexed Eugeo encounters Bercouli Synthesis One soaking in the bath. Meanwhile, Kirito and Alice are still climbing the Central Cathedral wall.

Seeing Alice’s reaction when he mentioned the name Selka, Kirito decides to tell her the truth about the Integrity Knights. Meanwhile, after being knocked unconscious during his battle with Bercouli, Eugeo awakes on the top floor of the cathedral.

Kirito and Alice reach the communal bath on the nintieth floor. There, they find the Integrity Knight Commander, Bercouli, who's been turned to stone by Chudelkin. Alice breaks down in tears upon seeing her mentor's tragic plight, but then...

Standing in Kirito and Alice's way is Eugeo, who's undergone the Synthesis Ritual and become an Integrity Knight. Kirito is rattled, until Alice admonishes him into resolving to fight Eugeo with everything he's got.

On the top floor of the Central Cathedral, Kirito, Eugeo, and Alice finally face Administrator. But Chudelkin uses the sacred arts to transform himself into a giant clown and attacks.

Cardinal appears on the top floor of Central Cathedral for a showdown with her bitter foe of the last two hundred years. She moves to achieve her objective of deleting Administrator, only to see the fallen sword golem rise up again.

Carrying the hopes of Cardinal, Eugeo, and Alice in his heart, Kirito stands yet again and visualizes the Black Swordsman, the top player who cleared SAO. For the sake of everyone he’s encountered in this world, Kirito, faces off with Administrator.

Six months have passed since the fierce battle against Administrator. Alice has brought Kirito to her childhood home, Rulid Village, where they live peacefully. Gazing out at the world that she saved with Kirito, Alice reflects on all that’s happened.

A force from the Dark Territory is attacking Rulid Village. Though she’d lost her purpose in battle, in order to fight for her family, and for the people that Kirito and Eugeo tried to protect, Alice takes up the Osmanthus Blade once again!

The mysterious group that attacked the Ocean Turtle turns out to be a secret unit under orders from the U.S. National Security Agency. And its leader, Gabriel, has battled Kirito and Sinon before.

Shasta, commander of the Dark Territory's dark knights, had intended to use Administrator's death as a chance for peace with the Human Empire. But his plans are thwarted by Emperor Vecta's return to the land of darkness.

Resolved to fight for humankind, Alice joins the forces of the Human Empire, bringing Kirito with her. But while the forces of darkness boast overwhelming numbers, only thirteen Integrity Knights are available to fight for the Human Empire.

The Final Load Test has begun, and the Eastern Gate has collapsed. Incited by Gabriel, now Emperor Vecta, the massive army of the land of darkness pushes on towards the Human Empire.

Integrity Knight Renly Synthesis Twenty-Seven, in battle for the first time, flees his position, allowing goblins from the forces of darkness to infiltrate to the tent where Kirito is.

The powerful formal art unleashed by the Integrity Knight Alice inflicts severe casualties on the forces of darkness. Alice encounters an enemy survivor and learns that Emperor Vecta's objective is to find the "Priestess of Light."

Upon seeing Alice, Gabriel orders his entire army to capture her. The pugilists guild races ahead of the main force. As Alice and Bercouli try to come up with a strategy to counter them, the silent Integrity Knight Sheyta Synthesis Twelve steps forward.

Asuna has logged into the Underworld using the superuser account of Stacia, the Goddess of Creation. After she descends, she is reunited with Kirito, thanks to Ronie and Tiese. But soon Alice arrives, leading to a precarious situation!

Asuna has created a bottomless chasm. The dark knights and the pugilists attempt to cross over to the other side, where the Human Empire Army waits. Meanwhile, Critter releases an announcement about a limited-time beta test for a bizarre new VRMMO.

Due to Gabriel's scheme, U.S. players were given black knight accounts, and are now continuously logging in to the Underworld. They begin mercilessly slaughtering soldiers from both the Human Empire Army and the Dark Territory Army.

Sinon has logged in with the super-account of Solus, the Sun Goddess and rescues Asuna and the others at the last minute. Meanwhile, Leafa logs in with the super-account of Terraria, the Earth Goddess, and descends to the Underworld.

Despite its modest size, the Human Empire Army and Asuna valiantly battle the wave of American players surging towards them. But they’re hopelessly outnumbered, and the Human Empire soldiers start to fall one after another.

Bercouli pursues Vecta, who’s abducted Alice. After a long, vicious battle, Bercouli unleashes his secret sword skill, Uragiri, and finally defeats Vecta, despite having sustained severe injuries himself.

The traitor inside Rath turns out to be a researcher named Yanai. When Higa attempts to restore Kirito, Yanai tries to thwart the operation by holding him at gunpoint. Meanwhile, in the Underworld, Sinon confronts Gabriel, who has logged back in.

Asuna and the others succumb to Vassago and the Chinese/Korean players. Discovering the catatonic Kirito, Vassago kicks his wheelchair over. Enraged, Klein lunges at Vassago, only to be pinned down by enemy players. Just then, someone unexpected appears.

Sinon manages to severely damage Gabriel, but her strength has been sapped. Leafa collapses after wiping out the American players. And Asuna, her situation now hopeless, gazes at Kirito. But the Black Swordsman continues to wander through his dreams.

Escaping his nightmares, Kirito regains consciousness at last. With the Night-Sky Blade in his right hand and the broken Blue Rose Sword in his left, he faces off against Vassago, armed with the Mate-Chopper, now enormous in size.

Alice and Asuna head to the World’s End Altar as Kirito confronts Gabriel. Unless he can defeat Gabriel and return to the real world before the maximum-acceleration phase begins, Kirito will have to spend the next 200 years in the Underworld.

The maximum-acceleration phase has begun. Alice successfully logs out of the Underworld, but Kirito doesn’t make it in time. In the real world, Higa and Kikuoka rush to shut down the STL, in order to disable the maximum-acceleration phase, but…

The “Rath Attack Incident,” masterminded by the American National Security Agency, is over. Now head of the newly formed Oceanic Resource Exploration & Research Institution, Rinko unveils Alice to the world as an authentic artificial general intelligence.

Rinko informs Kazuto that Alice is missing. He’s about to rush to the Rath Roppongi branch when the doorbell rings. In a panic, Kazuto throws open the door, only to find a deliveryman there with a huge cardboard box.
