List of Sword Art Online characters

The light novel, anime and manga series Sword Art Online contains a large cast of characters, most of whom are introduced as gamers who play and consequently become trapped in a virtual reality massively multiplayer online role-playing game (VRMMORPG). The series chronicles their interactions in multiple online worlds: Sword Art Online (SAO), Alfheim Online (ALO), Gun Gale Online (GGO), and Underworld (UW).

SAO players

Kirito

Kirito (キリト, Kirito) / Kazuto Kirigaya (桐ヶ谷 和人, Kirigaya Kazuto)

Voiced by: Yoshitsugu Matsuoka (Japanese); Bryce Papenbrook (English)

Kazuto, who uses the portmanteau "Kirito" as his character name, is a "solo" player who has been branded a "beater" (a combination of beta tester and cheater) by the players in Sword Art Online. When Kayaba announces that the players of SAO can no longer log-out without clearing the game, he quickly overcomes the shock. He power-levels to improve his odds of survival in the game, and emerges as a frontline floor-clearer known as the Black Swordsman (黒の剣士, Kuro no Kenshi). In SAO, he is the sole «Dual Blades» skill user. During his time in SAO, he falls in love with a female player, Asuna, and even marries her in-game. After the Sword Art Online incident, 300 people have yet to wake up, including Asuna. Kirito receives a picture from another virtual reality called Alfheim Online, in which Asuna was trapped in a cage on the legendary World Tree, which no ALO player has ever reached directly. Kirito decides to get a copy of the game and rescue Asuna nonetheless. Shortly after joining ALO, he befriends another player called "Leafa" (who is actually his cousin Suguha). Leafa helps Kirito grasp the game and offers to help him reach the World Tree. After a long journey and many adventures, Kirito manages to reach the World Tree and overcomes its obstacles to reach the top. He rescues Asuna and discovers Leafa's true identity. As ALO and SAO share the same game engine, among other features, a bug allows Kirito to retain most of the skills and money he obtained in SAO upon playing ALO with the same NerveGear, already beginning his journey with an advantage over other players. Despite this, he ends up being forced to discard all of his items (except the one containing Yui, which reformats itself as a navigation pixie), as they were not recognized by the system. Kazuto enrolls at the SAO Survivor School with Asuna and the other heroines in the real world. He is later asked to register in Gun Gale Online in order to investigate real life murders that are somehow linked with assassinations in-game. It is soon revealed that the murders are committed by ex-players from Sword Art Online, who were part of a player killing group known as Laughing Coffin. His actions result in the capture of two out of the three culprits. The last member escapes and is not heard of until the events of volume 9, and is responsible for an attempted murder of Kazuto. In the Alicization Arc, he has been assisting in the development of the fourth generation full dive interface, Soul Translator, by testing its thought acceleration functions. However, he has no memory of what he has been doing as a result of his memories being suppressed, voluntarily, by the system. He is attacked and poisoned by Johnny Black (The third culprit who escapes) in the real world and wakes up in UnderWorld with his memory of playing the game erased. He meets up with Eugeo and helps him out of some tough situations, during which he partially remembers his time with Eugeo and Alice during his "childhood" in UnderWorld. He then decides to aid Eugeo in finding Alice while he searches for a way out, back to reality. In the real world, he lives with his foster mother and aunt, Midori, and younger sister, Suguha, in a family of three. In fact, he was actually adopted by Minetaka Kirigaya and Midori Kirigaya when he was just a year old, due to his real mother and father passing away after an accident. However, Kazuto did not know this until he discovered the truth at the age of ten, and Suguha, being in fact the Midori's own daughter, was also unaware of Kazuto's adoption and is in actuality his cousin. This drove him into online playing; quitting Kendo, having a distant relationship with Suguha until his 2-year experience in SAO, and makes renews.

Asuna

Asuna is a friend and later to be wife of Kirito, and a sub-leader of the Knights of the Blood Oath, a medium-sized guild acknowledged as the strongest guild in Aincrad. Being one of the few girls that play SAO and extremely attractive, she receives many invitations and proposals. Asuna is a strong-willed, accomplished player known in-game as the "Flash" (閃光, Senkō) for her extraordinary fast sword skill. Later, she falls in love with Kirito and they marry in-game. Towards the end of the SAO arc, she saves Kirito from a killing blow by Heathcliff at the cost of her life. However, her death was only in-game and she is shortly reunited with Kirito shortly after his death defeating Heathcliff. Despite the completion of SAO, Asuna does not wake up and is instead detained in another virtual reality called Alfheim Online. She is forced to play the role of Titania the Queen of Fairies, with Nobuyuki Sugō, the man responsible for imprisoning her, playing as Oberon the Fairy King. This is done so that Sugō could marry Asuna in the real world, while she was unconscious, and thus take over RECTO Progress Inc. She attempts to get out of the World Tree where she is imprisoned and escape going so far as to steal a GM card which she throws out of the window when she hears Yui's voice. Upon being freed she created two avatars for Alfheim, Asuna (being the healer of the team) and Erika (a battle type avatar) and went on living with Kirito. She enrolls at SAO Survivor School with Kazuto in the real world. In the real world, Asuna lives a very stressful life, and is constantly pressured to fulfill her parents' high expectations. Before the SAO incident, she led her life unquestioningly according to her parents' demands. However, after living in SAO and meeting Kirito, she gains perspective and looks back on her past with disgust. She eventually becomes Kazuto's girlfriend, and dreams of marrying him and having a family with him in the real world.

Yui

Yui is shown to have a human form and a Navigation Pixie form where she is always barefoot in both forms. She was designed to monitor the emotions of players and appear at their sides to hear and help them out. However, since the moment everyone was imprisoned in Sword Art Online, she was forbidden to come in contact with the players and complete her prime directive. Unable to do anything but suffer as she monitored the emotions of the trapped players, she came upon Kirito and Asuna whose emotions stood out as a beacon of joy and peace in a sea of fear and despair. She sought them out, appearing to them as an amnesia child whom they adopted. In the end, she was nearly deleted by Cardinal, the management system of SAO. But Kirito saved her by converting and storing her data into his own NerveGear. Yui later shows up in ALO as a Private Navigation Pixie and helps Kirito along with Leafa to find Asuna. She refers to Kirito as "Papa" and Asuna as "Mama" and gets very annoyed if any girl other than Shinon, Leafa or Asuna gets close to Kirito.

Kyōji Shinkawa (新川 恭二, Shinkawa Kyōji) / Spiegel (シュピーゲル, Shupīgeru)

Shino's friend both in the real world and GGO, in fact he was the one who introduced Shino to GGO in the first place as a form of immersion therapy for her fear of guns. Kyōji wasn't trapped in SAO or affiliated with Laughing Coffin, but the pressures of being the next heir to his family's hospital due to his elder brother's frail health in the real world had a great psychological effect on him. Shōichi's tales as a red player also helped set him further down the path to murder and madness. Kyōji was the one who came up with the whole idea of Death Gun and enlisted the aid of the other two. It is also revealed that he is obsessed with Shino and wants the two to die together so that they can be reborn in a world like GGO (but is fine with a fantasy setting as well) because of his intense hatred of the real world and its pressures.

She entered the Academy in order to raise her family's social status.
