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.

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.

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.

Kirito’s determination to save Asuna borders on the insane. His reckless is stopped when Leafa suddenly logs out.

A man in a beat-up cloak watches Kirito fight his first battle and demands to know if he's "the real thing". The man has the tattoo of Laughing Coffin, a murderer's guild that existed within SAO. He tells Kirito that he'll kill him someday, and vanishes.

The man in the ragged cloak is an SAO survivor, and he might also be a player Kirito fought with to the death... This thought consumes Kirito, and his anguish is palpable - to the point that it worries Suguha.

BoB nears its end, and the only surviving players are Kirito, Sinon, and Dark Wind, the second place winner of the last tournament. Since Death Gun may have multiple partners, and Dark Wind may be in danger as well, Kirito decides to defeat him first. He acts as a decoy while Sinon snipes the enemy. Kirito's trust in her pays off as her bullet strikes true, and he finally faces off with Death Gun.

Death Gun's attack is modeled after Star Splash, a SAO skill that doesn't exist in GGO. Death Gun is skilled with not only a gun but a blade as well, and he gradually wears down Kirito's health. Meanwhile, Sinon's scope has been destroyed by Death Gun and she cannot attack, so she's forced to simply watch the fight. She grits her teeth and wonders if there's anything else she can 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.

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.

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.

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.

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.

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.

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.
