Synopsis[edit]

Setting[edit]
The light novel series spans several virtual reality worlds, beginning with the titular world of Sword Art Online. Each world is built on a game engine called the World Seed, which was initially developed specifically for SAO by Akihiko Kayaba, but was later duplicated for ALO, and later willed to Kirito, who had it leaked online with the successful intention of reviving the virtual reality industry.

Plot[edit]
In 2022, a virtual reality massively multiplayer online role-playing game (VRMMORPG) called Sword Art Online (SAO) is released. With the NerveGear, a helmet that stimulates the user's five senses via their brain, players can experience and control their in-game characters with their minds. Both the game and the NerveGear was created by Akihiko Kayaba.

On November 6, 10,000 players log into the SAO 's mainframe cyberspace for the first time, only to discover that they are unable to log out. Kayaba appears and tells the players that they must beat all 100 floors of Aincrad, a steel castle which is the setting of SAO, if they wish to be free. Those who suffer in-game deaths or forcibly remove the NerveGear out-of-game will suffer real-life deaths.

One of the players, named Kazuto "Kirito" Kirigaya, is one of 1,000 testers in the game's previous closed beta. With the advantage of previous VR gaming experience and a drive to protect other beta testers from discrimination, he isolates himself from the greater groups and plays the game alone, bearing the mantle of "beater", a portmanteau of "beta tester" and "cheater". As the players progress through the game Kirito eventually befriends a young girl named Asuna Yuuki, forming a relationship with and later marrying her in-game. After the duo discover the identity of Kayaba's secret ID, who was playing as the leader of the guild Asuna joined in, they confront and destroy him, freeing themselves and the other players from the game.

In the real world, Kazuto discovers that 300 SAO players, including Asuna, remain trapped in their NerveGear. As he goes to the hospital to see Asuna, he meets Shouzou Yuuki, Asuna's father, who is asked by an associate of his, Nobuyuki Sugou, to make a decision, which Sugou later reveals to be his marriage with Asuna, angering Kazuto. Several months later, he is informed by Agil, another SAO survivor, that a figure similar to Asuna was spotted on "The World Tree" in another VRMMORPG cyberspace called Alfheim Online (ALO). Assisted in-game by his cousin Suguha "Leafa" Kirigaya and Yui, a navigation pixie (originally an AI from SAO), he quickly learns that the trapped players in ALO are part of a plan conceived by Sugou to perform illegal experiments on their minds. The goal is to create the perfect mind-control for financial gain and to subjugate Asuna, whom he intends to marry in the real world, to assume control of her family's corporation. Kirito eventually stops the experiment and rescues the remaining 300 SAO players, foiling Sugou's plans. Before leaving ALO to see Asuna, Kayaba, who has uploaded his mind to the Internet using an experimental and destructively high-power version of NerveGear at the cost of his life, entrusts Kirito with The Seed – a package program designed to create virtual worlds. Kazuto eventually reunites with Asuna in the real world and The Seed is released onto the Internet, reviving Aincrad as other VRMMORPGs begin to thrive.

Soon after, at the prompting of a government official investigating strange occurrences in VR, Kazuto takes on a job to investigate a series of murders involving another VRMMORPG called Gun Gale Online (GGO), the AmuSphere (the successor of the NerveGear), and a player called Death Gun. Aided by a female player named Shino "Sinon" Asada, he participates in a gunfight tournament called the Bullet of Bullets (BoB) and discovers the truth behind the murders, which originated with a player who participated in a player-killing guild in SAO. Through his and Sinon's efforts, two suspects are captured, though the third suspect, Johnny Black, escapes.

Kazuto is later recruited to assist in testing an experimental FullDive machine, Soul Translator (STL), which has an interface that is far more realistic and complex than the previous machine he had played to help develop an artificial intelligence for the Ministry of Defense(MOD) named A.L.I.C.E. He tests the STL by entering a virtual reality cyberspace created with The Seed package, named UnderWorld (UW). In the UW, the flow of time proceeds a thousand times faster than in the real world, and Kirito's memories of what happens inside are restricted. However, Black injures Kazuto with suxamethonium chloride. The MOD recovers Kazuto and places him back into the STL to preserve his mind while attempts are made to save him.

Development[edit]
Reki Kawahara wrote the first volume in 2002 as a competition entry for ASCII Media Works' Dengeki Game Novel Prize (電撃ゲーム小説大賞 Dengeki Game Shōsetsu Taishō, now Dengeki Novel Prize), but refrained from submitting it as he had exceeded the page limit; he instead published it as a web novel under the pseudonym Fumio Kunori.[3] Over time, he added three further episodes and several short stories.[4][5] In 2008, he participated in the competition again by writing Accel World, this time winning the Grand Prize. Aside from Accel World, he was requested to get his earlier work, Sword Art Online, published by ASCII Media Works.[3] Kawahara agreed and withdrew his web novel versions.[5]

For the character protagonist Kirito, Kawahara was asked if Kirito's personality and character were based on his own; he answered that he usually does not put aspects of himself into his characters,[6] and jokingly remarked: "but if I had to say there was a point of similarity between Kirito and myself, it is the fact that neither of us are good at forming parties. We [both] tend to play solo in these games a lot."[7] Kawahara also noted that the female characters in the story were not based on anyone he knew in the real world, stating: "I don't usually make a character, setting, or anything before I start writing. As I write the story, the girls become what they are now. So, somehow, I don’t know exactly, but somehow, my subliminal idea or some hidden emotion creates the characters to be strong and capable."[6] Kawahara added that he wrote the series to demonstrate that he views online gaming not as a social ill or escape from real life, but rather decided to show games in a more positive light in his light novels.[6] He noted that "the character of Asuna I might have created a little too perfectly for Sword Art Online".[7]

There are a number of dōjinshi (fan works) written by Kawahara under the pseudonym Fumio Kunori, titled Sword Art Online Material Edition (ソードアート・オンライン・マテリアル・エディション).[19] An 80-page assemblage of some of the Material Edition volumes was published on February 13, 2011;[20] the latest release is Material Edition volume 19 on May 5, 2016. The author has also created some other dōjinshi including Lisbeth Edition, Silica Edition and Pina Edition under cooperation with Kurusu Tatsuya from ponz.info.[21][22] It is reported that these dōjinshi gain traction from the involvement of the original author in its creation process, as well as from supplying more details on characters from the original work.[21]

Reception[edit]
According to Oricon, Sword Art Online was the top selling light novel series of 2012, with eight volumes figuring among the top selling light novels.[128][129] It was ranked first in the 2012 and 2013 Kono Light Novel ga Sugoi! rankings, as well as top ten placement in 2011, 2014 and 2015.[130][131][132][133][134] It was also the second best selling light novel series for the first half of 2016 in Japan, selling 489,374 copies.[135] Sword Art Online: Progressive sold 321,535 copies in the same time period.[135] As of 2017, the series has an estimated 20 million copies in print worldwide.[136]

Richard Eisenbeis of Kotaku hails Sword Art Online as the smartest series in recent years, praising its deep insight on the psychological aspects of virtual reality on the human psyche, its sociological views on creating a realistic economy and society in a massively multiplayer online game setting, and the writing staff's ability to juggle a wide variety of genres within the series.[137] Eisenbeis particularly noted how the romance between Kirito and Asuna is explored bringing "definition to exactly what love is like in a virtual world."[137] However, at the time of this preliminary review, he had only watched the first 12 episodes of the series.[137] He has since gone on to review the second half of the series, lauding its excellent use of plot twists and praising its well written and believable villain. However, he felt that some of the initial positive aspects of the series were lost in the second half, such as the focus on psychological repercussions and social interactions that could be realistically seen in an online game. Criticism was also levied on the aspect of turning Asuna into a damsel in distress, stating that a female lead as strong as her was "reduced to nothing but the quest item the male lead is hunting for." Eisenbeis closes his review of the series by stating in regards to the two halves, "Both, however, are enjoyable for what they are."[138]

Rebecca Silverman of Anime News Network has criticized the series as having pacing problems, logical gaps, and "sloppy writing".[139] Theron Martin of Anime News Networkcriticized the story as struggling "to achieve and maintain the level of gravitas that life-or-death danger should have", while calling it unwilling to commit to Kirito's "lone wolf" image.[140] DeviceCritique explains that Sword Art Online influences the virtual reality market to grow, and references the Oculus Rift as a prime example of the starting point of virtual reality. It also praises Sword Art Online for exploring the psychological and social aspects of virtual reality gaming.[141] Adam Facey of The Muse criticized the series, among others, as being sexist and the female characters as being overly sexualized.[142]
