A virtual reality gaming console known as the "NerveGear" is released to the public alongside the world's first virtual reality game called "Sword Art Online" (SAO). A beta-tester named Kirito logs in and visits Aincrad, the setting where the game takes place, and quickly befriends a fellow novice player named Klein, to whom he teaches the basics of the game, including how to defeat a boar. A few hours later, Kirito and Klein discover that they cannot log out. Akihiko Kayaba, the game's creator and employee of the computer corporation Argus, announces to the players that he intentionally removed the option to log out and that players will die if either their NerveGear helmet is forcefully removed or their in-game health bar is depleted to zero. He also admits that he created this game as a way to become God over his own dominion, and that the only way to log out of the game is to clear all of Aincrad's 100 Floors.

When Illfang's health becomes low, Diavel goes for the finishing attack, but before Diavel can see Illfang's true weapon, he is mortally wounded. With his dying breath, Diavel tells Kirito to defeat the boss and save the players at all costs. After Kirito successfully defeats Illfang, the other players accuse Kirito of killing Diavel by having previous knowledge about Illfang he did not share with other players and label him a "beater", a combination of the words "beta-tester" and "cheater". Kirito accepts the title and claims the prize for defeating Illfang: a black leather trench coat that quickly becomes his trademark. He then becomes the first player to clear the first floor by stepping through the gate.

Afterwards, Kirito travels to the 35th Floor, where he defeats a secret boss named Nicholas the Renegade, to obtain an item capable of reviving a dead player.

Kirito takes on the group by himself, unable to break their formation. Yui tells Leafa to cast some protective magic on Kirito, while he conjures an illusion spell that temporarily transforms him into a representation of the Gleam Eyes. In his new form, Kirito obliterates his enemies, but spares one whom Kirito bribes with game items in exchange for information. The Salamander reveals that his party was ordered by Kagemune to attack Kirito and Leafa.

Due to disbelief, Eugene challenges Kirito to a duel, but Kirito, having borrowed Leafa's sword, wins using his duel wielding technique, forcing the Salamanders to retreat. Sakuya, leader of the Sylphs, contacts Sigurd and banishes him from the race for his betrayal. Since the Sylphs and Cat Siths are now in an alliance and plan to assault the World Tree in a few days, Kirito donates a large sum of money to Alicia Rue, leader of the Cat Siths, before he and Leafa continue their journey to the World Tree. Meanwhile, Asuna escapes from her cage to find a way out of the World Tree.

On the way there, he tells her that he will be put in a special school for students who were formerly SAO players to catch up on the school they missed while logged in to SAO.

She attempts to log out of the game by using the gamemaster console inside the room, but is captured by two of Oberon's assistants. However, she manages to snatch a key card before she is thrown back into her cage. Yui informs Kirito and Leafa that Asuna is at the top of the World Tree.

Kirito rushes towards the top of the World Tree, but finds it blocked by a barrier. Yui desperately calls out to Asuna, in which the latter drops down the key card in response. Once Kirito catches the key card, which can be used to access the gamemaster console, Yui is certain that it came from Asuna. Kirito bids farewell to Leafa and embarks on the Grand Quest by himself, entering inside the dome filled with Guardian Knights. Despite his best efforts, Kirito is overwhelmed by the Guardian Knights and runs out of health. Shortly afterwards, Leafa enters the dome and grabs Kirito's Remain Light, his soul of flame left behind, before successfully escaping to revive him. Leafa attempts to talk Kirito out of reentering the dome alone, but he remains determined and inadvertently mention "Asuna". Leafa then realised that Kirito is Kazuto's avatar, and log out in despair. In the real world, Kazuto approaches Suguha, who reveals in great anguish that she knew they were not true siblings and that she has fallen in love with both him and his avatar.

Kazuto thinks back to the time when he was ten years old and learned that he was not related to Suguha, which resulted in him becoming detached from his family and increasingly engrossed with online gaming. Wanting to sort things out, Kazuto asks Suguha to meet him in ALO. As Leafa contemplates whether she should stop seeing her brother in-game, she challenges Kirito to a one-on-one duel. They both end up throwing away their swords and apologize to each other. After Kazuto explains that he is unable to say what he thinks of Suguha until Asuna is rescued, Leafa agrees to help him in the Grand Quest this time around, convincing Recon to join them as well. Just as things begin to look dire against the Guardian Knights inside the dome, the Sylphs and the Cat Siths arrive to help. Using his sword combined with Leafa's sword, Kirito breaks through the top of the dome. Yui guides Kirito in using the key card to open the gate to the top of the World Tree.

Arriving at the top of the World Tree, Kirito and Yui finally reunite with Asuna. However, they are suddenly hit by high gravity magic, which forces Yui to retreat, and they are confronted by Oberon. As Oberon reveals that his mind control experiments are almost complete, he chains Asuna and molests her in front of Kirito. Falling into despair, Kirito hears the voice of Akihiko, who encourages him to stand up and fight. Using Akihiko's administrative functions, Kirito removes Oberon's powers and challenges him to a fight with no pain absorption, and shows Oberon the true meaning of pain before destroying him. After logging Asuna out to ensure her safety in the real world, Kirito meets with a remnant of Akihiko's memory, who gives him an item called the World Seed before leaving. Kirito respawns back at the World Tree, where Yui returns after hiding inside of Kirito's NerveGear storage. Kirito logs out of ALO, and in the real world, Kazuto heads to the hospital where Asuna is waiting.

Upon arriving outside the hospital, Kazuto is attacked by Sugō wielding a knife. However, Sugō's poor eyesight prevents him from killing Kazuto, who disarms Sugō yet ultimately spares his life. Kazuto and Asuna reunite and share a kiss in her hospital room. The two attend the special school for students who were formerly SAO players. Sugō is arrested for his cybercrimes, the 300 SAO players were released from the hospital, RECT Progress Inc. was dismantled and ALO was shut down. Akihiko committed suicide by using his NerveGear after SAO had collapsed. Kazuto, Asuna and Suguha visit Andrew at his café, where Ryōtarō "Klein" Tsuboi, Keiko "Silica" Ayano, Rika "Lisbeth" Shinozaki, Yolko, Caynz, Yulier, Thinker and Sasha congratulate Kazuto for completing SAO and ALO. The World Seed created by Akihiko is a program package replacing the Cardinal System, the game system for SAO and ALO, thus reviving the virtual reality gaming genre. Suguha as Leafa returns to Alfheim, and Kazuto as Kirito catches her in midair when she falls from flying too high. After the two dance in the sky, Kirito takes Leafa to New Aincrad, vowing to start from scratch and clear all 100 Floors of this floating castle.

Suguha Kirigaya meets with Asuna Yuuki, Keiko Ayano and Rika Shinozaki in order to learn how to swim in the school swimming pool. Meanwhile, Kazuto Kirigaya goes to the school counseling office and meets Seijirō Kikuoka, a member of the Virtual Division of the Ministry of Internal Affairs and Communications, who investigates matters concerning the SAO incident in order to fully grasp the motives behind Akihiko Kayaba. Kazuto recounts and reflects on his experience while in Aincrad in SAO, while Suguha is told about Kazuto as Kirito and the times he spent with Keiko as Silica, and Rika as Lisbeth, as well as how he developed feelings for Asuna while in SAO. Kazuto then explains his experience while in Alfheim in ALO, recalling his mission with the help of Suguha as Leafa to rescue Asuna from Nobuyuki Sugō as Oberon the Fairy King at the World Tree. Suguha eventually learns how to swim and Kazuto finally finishes the meeting. While in ALO, Kazuto, Asuna, Leafa, Yui, Klein and Agil go to Turtle Island in preparation for a quest with a giant whale as their reward. They dive into the ocean and arrive at an undersea temple where they meet a non-player character named Nerakk, who asks the group to find a pearl inside the undersea temple. After exploring the undersea temple and finding the pearl, it is revealed that the pearl is the Child's Egg, an egg containing a strange creature inside, and that Nerakk is actually Krakken the Abyss Lord, the boss of the quest. The battle is interrupted by another non-player character named Leviathan the Sea Lord, who forces Krakken the Abyss Lord to retreat and collects the Child's Egg, thereby clearing the quest. The group returns to the surface on the back of the giant whale. After the credits, Kazuto's phone rings back at his house, with the ID reading Seijirō Kikuoka.
