Sword Art Online Virtual Reality Game
Janet Denzel
Virtual reality (VR) came along with the promise of in-game immersion, and in some aspects, it succeeds, especially if by immersion you mean the feeling of stomach-dropping nausea you get from a roller coaster. While strapping on a VR headset and some headphones do provide a more immersive experience than a computer screen or television, there are still some aspects missing.
Even the iconic 1999 sci-fi blockbuster The Matrix could loosely be considered a type of full-dive VR. Instead of using headsets and interfaces to control virtual avatars, the characters in the movie were connected to the virtual world by a neural link connected directly into their brain stems.
Haptic feedback suits are still currently only available in science fiction, though a few prototypes are in the works. Once the technology catches up with our imaginations, these suits will provide sensory feedback, usually in the form of pressure and vibration, over the entire body.
Elon Musk, of Tesla and SpaceX fame, is also working on the first functional man-machine interface, allowing us to control computers with nothing more than the power of our thoughts. In 2021, he released a video showing a monkey with one of his NeuraLink implants, capable of playing simple video games with its mind.

Sword Art Online has received widespread commercial success, with the light novels having over 30 million copies sold worldwide. The anime series has received mixed to positive reviews, with praise for its animation, musical score, and exploration of the psychological aspects of virtual reality, but criticisms for its pacing and writing.
The light novel series spans several virtual reality worlds, beginning with the game, Sword Art Online (SAO), which is set in a world known as Aincrad. 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 Alfheim Online (ALO), and later willed to Kirito, who had it leaked online with the successful intention of reviving the virtual reality industry. A third world known as Gun Gale Online (GGO) appears in the third arc and is stylized as a first-person shooter game instead of a role-playing game, and is the main setting of Alternative Gun Gale Online. It was created using the World Seed by an American company. A fourth world appears in the fourth arc known as the Underworld (UW). The world itself was created using the World Seed as a base, but it is as realistic as the real world due to using many powerful government resources to keep it running.
In 2022, a virtual reality massively multiplayer online role-playing game (VRMMORPG) called Sword Art Online (SAO) was 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 were created by Akihiko Kayaba. On November 6, 10,000 players log into 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. He also states that those who suffer in-game deaths or forcibly remove the NerveGear out-of-game will suffer real-life deaths.
A player 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 woman 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 "Heathcliff", the leader of the guild Asuna joined in, they confront and destroy him, freeing themselves and the other players from the game.
One year after the events of SAO, 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 test an experimental FullDive machine, Soul Translator (STL), which has an interface far more realistic and complex than the previous machine he had played, to help RATH, a research and development organization under the Ministry of Defense (MOD), develop an artificial intelligence named A.L.I.C.E. He tests the STL by entering the Underworld (UW), a virtual reality cyberspace created with The Seed package. 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, when Johnny Black ambushes and mortally wounds Kazuto with suxamethonium chloride, RATH recovers Kazuto and places him back into the STL to preserve his mind while attempts are made to save him. During his time in Underworld, Kirito befriends Eugeo, a carver in a small village of Rulid, and helps him on a journey to save Alice Zuberg, his friend who was taken by a group of highly skilled warriors known as the Integrity Knights for accidentally breaking a rule of the Axiom Church, the leaders of the Human Empire. He and Eugeo soon find themselves uncovering the secrets of the Axiom Church, led by a woman only known as "The Administrator", and the true purpose of Underworld itself, while unbeknownst to them, a war against the opposing Dark Territory is brewing on the horizon. They meet Alice, now an Integrity Knight, and though she does not remember them, Kirito helps her remember her true identity: a form of true artificial intelligence known as A.L.I.C.E. In the battle against the Administrator, Kirito manages to slay her, though Eugeo dies in the process, to Kirito's dismay.
Meanwhile, in the real world, conflict escalates as American forces raid RATH's facility in the Ocean Turtle in an effort to take A.L.I.C.E. for purposes unknown. Two of the attackers - Gabriel "Vecta" Miller and Vassago "Prince of Hell" Cassals - take control of two Dark Territory characters as they unite the Dark Territory's inhabitants to aid them. With help from all his friends, Kirito manages to stop the attackers as well as foreign players lured by Vassago, and safely extract A.L.I.C.E. from UW, who gains a physical body - with Gabriel and Vassago being killed both virtually and physically in the process. However, Kirito does not log out in time before the flow of time is restored and spends 200 years in UW (about 2 weeks in the real world) with Asuna, who stayed behind for Kirito. After awakening they have their memories of 200 years in underworld removed under Kirito's request, though RATH employee Takeru Higa secretly keeps a backup consciousness of his 200-year self, who have unknown plans for the Underworld.
One month later, Kirito, Asuna, and the others have their accounts forcibly migrated to Unital Ring, a new VRMMORPG which incorporates locations from all the other environments they previously visited, and investigate the cause while meeting some familiar faces.
Reki Kawahara wrote the first volume in 2001 as a competition entry for the 2002 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.[4] Over time, he added three further main arcs and several short stories which, like the first arc "Aincrad", were later adapted into the light novels.[5][6][7] 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.[4] He agreed and withdrew his web novel versions.[7]
For the 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, 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."[8] He 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." He 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. Kawahara also noted that the character of Asuna might have been created a little too perfectly.[8]
After Kawahara's request for Sword Art Online to be published was approved,[4] he started working with illustrator abec on the light novel series. The first volume was published in print on April 10, 2009,[9] and 27 volumes have been published as of October 7, 2022.[10] The first eight volumes of the light novel series told the story arcs for Sword Art Online, Alfheim Online, and Gun Gale Online. The Alicization story arc was covered by volumes 9 through 18, while volumes 19 and 20 told a side story called Moon Cradle. Kawahara plans on writing "one more big arc" called Unital Ring that will go back to the real world, and it is the first arc not based on the original web novel. The Unital Ring story arc began in volume 21, which was released in Japan on December 7, 2018.[11]
