In 2026, four years after the infamous Sword Art Online incident, a revolutionary new form of technology has emerged: the Augma, a device that utilizes an Augmented Reality system. Unlike the Virtual Reality of the NerveGear and the Amusphere, it is perfectly safe and allows players to use it while they are conscious, creating an instant hit on the market. The most popular application for the Augma is the game Ordinal Scale, which immerses players in a fantasy role-playing game with player rankings and rewards. Following the new craze, Kirito's friends dive into the game, and despite his reservations about the system, Kirito eventually joins them. While at first it appears to be just fun and games, they soon find out that the game is not all that it seems...

The most popular application for the Augma is the game Ordinal Scale, which immerses players in a fantasy role-playing game with player rankings and rewards. Following the new craze, Kirito's friends dive into the game, and despite his reservations about the system, Kirito eventually joins them. While at first it appears to be just fun and games, they soon find out that the game is not all that it seems...

The only way to escape is to ‘clear’ the game. Death in game means actual ‘death’ —- The ten thousand who have logged onto the as of yet mysterious game ‘Sword Art Online’ using their Nerve Gear have been forced into this perilous death game and are trapped inside. Protagonist Kirito, one of the many gamers, has greeted this ‘truth’. He plays as a solo player in the giant castle that is the stage for this game —- ‘Aincrad’. To meet the conditions of clearing the game and leaving this twisted virtual world, he must get through all 100 floors. Will Kirito have what it takes to clear the game, or will he die trying?

"Where...am I...?" Before he knows it, Kirito has made a full-dive into an epic, fantasy-like virtual world. With only a murky recollection of what happened right before he logged in, he starts to wander around, searching for clues. He comes upon an enormous, pitch dark tree (the Gigas Cedar), where he encounters a boy. "My name is Eugeo. Nice to meet you, Kirito." Although he is supposedly a resident of the virtual world – an NPC – the boy shows the same array of emotions as any human being. As Kirito bonds with Eugeo, he continues to search for a way to log out of this world. Meanwhile, he remembers a certain memory deep down within him. He remembers racing through the mountains with Eugeo as a child... A memory that he should not have in the first place. And in this memory, he sees someone other than Eugeo, a young blond girl. Her name is Alice. And it is a name that must never be forgotten... (Source: Aniplex USA)

The final battle against the Dark Territory drags on, as players from all over the world flood the Underworld's servers and plunge the Human Empire into utter chaos. Asuna Yuuki and her friends defend their new allies with everything they have, but their numbers are falling. Meanwhile, Alice Zuberg heads toward the World's End Altar while Gabriel "Vecta" Miller relentlessly pursues her. Meanwhile, members of Rath strategize a plan in an attempt to restore Kirito's damaged fluctlight. However, the intruders occupying the main control room have other plans. Surrounded by death and despair, when all hope seems to be lost, one voice reaches out to Kirito—a familiar one saying, "I will always be by your side." Sword Art Online: Alicization - War of Underworld 2nd Season is the epic conclusion to Akihiko Kayaba's dream of creating artificial human intelligence. Now it is up to Kirito and his friends to protect this collapsing world from the people that still think it is just a game.

Yui wants to see a whale with Kirito during an underwater quest in Alfeim Online. During the quest however, it is revealed Leafa cannot swim. Asuna and the other female characters decide to train Suguha in a real-world pool to help her in ALO. Meanwhile, Kirito meets a certain someone.

The story is set a couple of years after the events of Sword Art Online, where Kazuto "Kirito" Kirigaya and his sister Suguha meet up with Asuna Yuuki, Rika "Lisbeth" Shinozaki, and Keiko "Silica" Ayano at the SAO Survivor School. Kirito then attends emergency counseling, while the girls go for a swim at the pool. It turns out that said "emergency counseling" is a subterfuge set up by Seijirou Kikuoka, aiming to rehash the incident of Sword Art Online in hopes of determining Akihiko Kayaba's motives. What will the girls get up to in the pool, and what awaits Kirito and his "counseling"?

Excelling socially and academically, Asuna Yuuki is on track to ace her high school entrance exams. Her friend and classmate, Misumi "Mito" Tozawa, advises her to take a short break from studying and join her on the launch day of Sword Art Online (SAO)—the highly anticipated online virtual reality multiplayer game. Asuna accepts her offer and soon meets her in the game. In a cruel twist of fate, Asuna, Mito, and every other player logged into SAO find themselves trapped in the game permanently. The only way out is to clear all one hundred floors of the game, and to make matters worse, dying inside the game will kill the player in real life. With SAO now turned into a nightmare death trap, Asuna and other gamers—such as the lone swordsman Kazuto "Kirito" Kirigaya—must adapt and survive, all whilst attempting to beat the unforgiving competition to the top.
