Plot Overviews

Main article: Aincard Arc

In the year 2022, Yuuki Lamia (the main protagonist), a solo player who had the luck-of-the-draw to play the beta version, and the many other players of Sword Art Online (SAO) are trapped inside of a game, unable to logout; the only way to live is to win. Death in-game means death in the real world; tampering with or prolonged power outages to the NerveGear, the gear that simulates in-game character control by redirecting brain signals, also means death. To win means to defeat the final boss on the top floor; out of the original 10,000 players at the start, two years later, over 6,000 remain with 26 floors left to clear.

Volume 2 also contains four side stories that take place within two years of the SAO incident.


A girl who is nicknamed the second savior of France «Joan d`Arc», starts playing SAO in order to save people from self-deprivation. Soon after saving several Red Players, she becomes known as the Savior of the Red Player and an enemy that must be exterminated, even Cardinal agrees to issue a quest to kill Joan. Fortunately, she is saved by Yuuki Lamia, who betrays her guild in order to save Joan, believing that is the right thing to do. When Joan is killed while the two are trying to escape, after Joan dies in her arms, Lamia decides to find an event item that can revive her. A friend gives her an event item, that saves Joan and revives her. Now with targets on their back, the two must beg for protection from somebody named «Jack the Ripper», in order to escape persecution. Will Jack the Ripper give them shelter or murder them on the spot along with the Green Players hunting them?


A red player, Emilia decides to resign from the profession to raise her in-game children; twins Erika and Julian. When her husband is killed and children are killed by green players, Emilia decides to try and become Kami (or God in English), so that her children may be revived. To save Emilia from self-deprivation, Joan and Lamia go on a quest to seek pictures of Emilia`s killed family members to make her remember what she loved most about them. Will they succeed or fail?

The Last Hero

A young girl player, called Princess Eugene in SAO becomes a savior to the Green Players and is elevated to the status of Queen, revered as a kind and generous ruler. However, a redeemed Emilia is deeply suspicious of this so-called "Queen", thinking that she might be a red player in disguise. She decides to gather more information and learns that this so-called "Queen" has murdered people before and has proclaimed herself "redeemed". She goes to her friends, telling them of her suspicions, and they are interested to hear what she has to say about this "Queen". Later on, they learn that Emilia was right to hold suspicions about her as she was a red player in disguise. Now they have to take this "Queen" hostage and bring her before the Elder Court.

The Governments around the world are seeking to eradicate them, so they seek the aid of the Knight Slayer, Yuuki Lamia, and the Savior of Hope and Dreams, Joan d`Arc to save them from being killed. Lamia, as usual, wants nothing to do with them, but Joan believes that they can help their cause in some way. However, after a series of adventures with them, Joan changes her mind seeing them as psycho liars and scum that should be eliminated for the good of all that walks the earth, a point that scores her unfailing popularity with the red players and the green players. The governments also congratulate the two for choosing the right choice.

Alicization (Fourth Arc, Project Alicization [PA])

Main article: Alicization Arc

Lamia awakens to find herself lost in a new world. With the realistic world and her "lost" memories with this world,s he questions her own identity and her existence in the world he used to know and the worlds he is currently in. She soon finds out that this is a virtual world with the name "Underworld", and pursues to find the truth about this world and the objective of Rath for making this realistic world.


The first part of the arc begins with Lamia, Eugeo and Alice, setting out to explore a cave said to harbour a dragon and ice. After entering the cave the trio leave and pass close to the "Dark Territory", where a terrible mishap occurs, and Alice is taken away from her village by an Integrity Knight to be tried and executed for breaking the Taboo Index, the "absolute law" of the Axiom Church. However, Eugeo believes she is still alive. Six years later, Lamia reappears, and she helps Eugeo in his Sacred Task, by cutting down a demon tree known as the Gigas Cedar, so that they can go find Alice at the top of the Cathedral tower.


During the confrontation with Johnny Black, Lamia was injected with a deadly dose of succinylcholine, which put her into a coma. After her condition was stabilized, she mysteriously disappeared while being transported to a hospital, and Kazuto set out to find her. With the help of Yui and Koujiro Rinko, he found Lamia in the custody of Kikuoka Seijirou in a secret government base in the Pacific Ocean, where Lamia was being treated to have her neural network restored with the help of the Soul Translator, the fourth generation FullDive system that Kazuto had been testing. There she learns the truth about Project Alicization and why the Soul Translator was created. Meanwhile, Lamia and Eugeo journeyed to the south of Rulid, to a large settlement in the northern area of the empire called Zakkaria to participate in the Zakkaria Sword Arts Tournament to continue on their journey to gain access to the Central Cathedral, where Alice was supposed to be held.


Now in the second year of the North Centoria's Imperial Sword Mastery Academy, Lamia and Eugeo were working their way up to the top of the Academy's ranks to be given the right to participate in the Norlangarth North Empire Empire Swordsmanship Tournament and, later, the Four Empires Unity Tournament. However, after a certain incident midterm, they both ended up breaking the Taboo Index and were arrested by an Integrity Knight, who turned out to be Alice, with no memory of her life in Rulid. After escaping the Axiom Church's jail and an encounter with another Integrity Knight, they were saved by the world's Cardinal, which had taken the form of a human avatar and no longer in control of Underworld. From her, Lamia learned the secret of the Axiom Church and its immortal ruler, Quinella.


The story of Cardinal continues from the previous book. Quinella, the ruler of the Axiom Church was a Fluctlight whom became the "Administrator" of Underworld after merging the world's Cardinal System into herself, and obtaining eternal youth. However, after a conflict within herself, and an attempt to rectify errors which this change caused, the being calling herself "Cardinal" was separated from Quinella. After a brutal battle, Cardinal retreated into a Library that had no physical entrance. After learning the truth behind the Axiom Church's existence, Lamia learned of Rath's plans with the residents of Underworld, and the terrible war that was sure to come. She became intent on stopping it, but had to first put an end to Quinella's actions. She and Eugeo are then sent to retrieve their swords, and must then climb the 100 floors of the Central Cathedral, fighting the Integrity Knights within the tower, while simultaneously honing their skills and becoming stronger.


Lamia and Alice were sent flying from the 80th floor after the pair's swords had clashed with great power and created a hole in the side of the tower. The two hung on for dear life and agreed to a truce until they could return into the tower. As they climbed up the side of the tower, they noticed creatures from the Dark Territory, the gargoyles. Meanwhile, Eugeo forged onward without his partner. As he went up the floors, he encountered Integrity Knight Bercouli Synthesis One in the bathing area and defeated him by using the Armament Full Control Art of his Blue Rose Sword. As Bercouli fainted, a small clown-like person entered the scene and jumped to Eugeo. Eugeo then blacked out due to the effects of his Blue Rose Sword's freezing and «Life» draining ability. Outside the Cathedral, during a chat with Alice, Lamia mentioned her sister, Selka, unintentionally triggering her lost memories. As Alice decided to walk out of her duties as an Integrity Knight, her Seal of the Right Eye, the same phenomenon that occurred to Eugeo, was activated. Alice suffered immense pain in her right eye with a warning being displayed on it, before her eye burst, breaking the seal. Lamia then promised her that he would lead her to Selka one day after they defeated the Administrator.


Having managed to re-enter the Cathedral with Alice and encountered Eugeo, now turned into an Integrity Knight by Quinella, Lamia engaged in battle with her friend, until Eugeo managed to regain control of himself and used his Armament Full Control Art to freeze his friends temporarily in order to return to Quinella. After breaking the ice, Lamia and Alice finally reached the 100th floor, where they discovered that Eugeo had unsuccessfully used the special dagger against Quinella. The three of them then worked together and defeated Chudelkin.
