Sword Art Online: 10 Strongest Characters, Ranked

Countless gamers were hoping to get their hands on a video game similar to Sword Art Online. Players could enter virtual reality by putting on the Nervegear and control their character. Their only option was to complete all levels and eventually beat the strongest boss on the 100th level. Some players had an advantage as they took part in beta testing, therefore they knew the game much better.

Still, there were participants, who were born heroes of virtual reality. Players were fighting for their lives and improved their skills so they could reach the next level. Sword Art Online quickly became one of the most dangerous and difficult games the players ever had to play. While the game was brutal it gave fans some of the most exciting and powerful characters.

10 Quinella

Quinella, who referred to herself as Administrator was the main antagonist in the Alicization Arc’s first half.  The over 350-year old character was a pretty tough ruler in her world.

Quinella was very strong and had everyone in her hand, but probably she was a little too confident. She was often in a dormant state and only woke up to take a quick look at her subordinates. However, after her clash with Alice, Eugeo, and Kirito, she had to retreat and was eventually killed.

9 Leafa

In the real world, she was known as Kirigaya Suguha, a middle school student with short black hair. Once she entered the SAO world, everyone knew her as Leafa. She was a very energetic character in the series who was able to defeat a number of opponents.

Leafa was often quite surprising as her character didn’t suggest as much aggression as she occasionally displayed. When she was annoyed or the situation demanded, Leafa never hesitated and was able to defeat most of her enemies.

8 General Eugene

The Salamander armed forces’ leader proved to be very strong over the series. Without a doubt, he was the strongest in his group and he was always looking for tough challenges.

He didn’t engage in a fight with others, who seemed weaker than him. Besides his physical abilities, he was wearing the ultra-rare Blood armor and fought with the second strongest sword in the game. Thanks to his equipment, he was considered the strongest character in ALfheim Online for a good while.

7 Sinon

Asada Shino AKA Sinon was a huge game nerd, who first began playing with Gun Gale Online to overcome her fear of guns. Later, she started playing with Sword Art Online as a Cait Sith archer. She mastered shooting to such a high level, she was able to hit her targets from over two hundred meters.

Sinon became stronger and stronger as she managed to deal with her childhood trauma. While she usually remained cool in fights, she was often seen as violent and angry.

6 Alice

Alice is a remarkably strong character in Sword Art Online. Quinella kidnapped her and turned her into an Integrity Knight. Later she showed her true powers when she fought against Quinella alongside Kirito and Eugeo. Alice was a strong-willed character, who wouldn’t ever back out from any challenge. She wanted to master the Sacred Arts to become even stronger.

Fans thought Alice was among the most important characters because without her Kirito may have died.

5 Yui

Yui was actually an AI, whom Kirito and Asuna found upon their investigation of a ghost in a forest. The little girl seemed to have lost all her memories and the couple looked after her. As time passed she proved to possess extraordinary powers such as being able to track every player’s real-life location and rewrite codes in the system.

Yui was also able to jump between virtual worlds. Yui became one of the most belovedSAO characters and inspired many fan art and cosplays.

4 Oberon

Fairy Dance Arc’s antagonist Fairy King Oberon shocked fans with his incredible greediness and cruelty.

His real name was Sugou Nobuyuki, chief of the RECT Inc research institute and Asuna’s husband. He hacked into the game and managed to reroute 300 players for his research. He thought of himself as a god, which proved to be a fatal mistake, as Kirito managed to finish him. Oberon was among the strongest characters, but his intellect and deviant personality made him extremely dangerous.

3 Asuna

Asuna was very difficult to beat by her opponents, thanks to her Sword Skills. In the beginning, she wasn’t worried about dying, because she felt lost and didn’t want to return to the real world. That made her even more dangerous, but when she met Kirito, Asuna found a new meaning in her life. From that on she was invincible and among the most motivated characters in Sword Art Online.

Generally, she was a caring and helpful person, who never left anyone behind.

2 Heathcliff

For many, he was known as Kayaba Akihiko, SAO’s creator, and founder. Without a doubt, he was one of the strongest characters, since he knew the game inside out. Additionally, he possessed the first unique skill called the Holly Sword.

Due to using the Liberator set, he was very quick in combat. He was also famous for being able to engage alone with the 50th floor’s boss for ten minutes. Although he was considered to be the main antagonist, he was very soft-spoken. Still, fans knew he must have been a psychopath for sentencing so many people to death.

1 Kirito

Narusaka Kazuto or Kirito was a true hero everyone looked up to. He helped the weak and supported those worthy of his sympathy. He was one of the beta testers therefore he knew the game much better than most.

Throughout the series, Kirito was always great at combat, never wasted time, he was kind to other players, and fans grew very fond of him. Kirito adapted quickly to every change that occurred in the game and remained calm at all times. His relationship with Asuna made him even more motivated to get out alive.

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 FPS game instead of an RPG, 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) 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 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.

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 Asuna's father Shouzou Yuuki 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.

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 develop artificial intelligence for RATH, research, and development organization under the Ministry of Defense (MOD), named A.L.I.C.E. He tests the STL by entering 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, when Black ambushes and injures 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 Pontifex", and the true purpose of Underworld itself, while unbeknownst to them, a war against the opposing Dark Territory brewing on the horizon. 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 Miller and Vassago Cassals - take control of two Dark Territory characters as they unite the Dark Territory's giants, goblins, ogres, orcs, dark knights, dark mages, and pugilists 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 Miller and Vassago being killed in the process.

One month later, Kirito 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.[3] 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.[4][5][6] 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] He agreed and withdrew his web novel versions.[6]

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,[7] 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."[7] 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.[7] Kawahara also noted that the character of Asuna might have been created a little too perfectly.[8]

The Unital Ring story arc began in volume 21, which was released in Japan on December 7, 2018.[11]

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).[21] An 80-page assemblage of some of the Material Edition volumes was published on February 13, 2011;[22] another, Material Edition: Remix, was published on September 6, 2019. The latest release is Material Edition volume 29 on May 12, 2019. The author has also created some other dōjinshi including Lisbeth Edition, Silica Edition and Pina Edition under cooperation with Kurusu Tatsuya from[23][24] 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.[23]

Live-action series[edit]

Sword Art Online is a planned American live-action television adaptation of Sword Art Online. Skydance Television announced on August 2, 2016, that they had acquired the global rights to produce a live-action television adaptation of Reki Kawahara's Sword Art Online light novel series.[151]Laeta Kalogridis has been attached to write a script for the pilot, and will also serve as executive producer for the series alongside Skydance CEO David Ellison, Dana Goldberg, and Marcy Ross.[151] Skydance has stated their intent to "fast-track" the launch of the series,[151] along with plans to follow the TV series with the release of a Sword Art Onlinevirtual reality experience.[152][153] In February 2018, it was reported that the live-action series had been sold to Netflix.[154]


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.[155][156] It was ranked first in the 2012 and 2013 Kono Light Novel ga Sugoi! rankings, as well as top five placement in 2011, 2014, 2015, 2016, 2017, 2018 and top 10 in 2019.[157][158][159][160][161] It was also the second best selling light novel series in the first half of 2016 in Japan, selling 489,374 copies.[162]Sword Art Online: Progressive sold 321,535 copies in the same time period.[162] As of 2017, the series has an estimated 20 million copies in print worldwide.[163] As of 2021, the series has 26 million copies in print.[164]

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.[165] Eisenbeis particularly noted how the romance between Kirito and Asuna is explored bringing "definition to exactly what love is like in a virtual world."[165] However, at the time of this preliminary review, he had only watched the first 12 episodes of the series.[165] 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 towards 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."[166]

Rebecca Silverman of Anime News Network has criticized the series as having pacing problems, logical gaps and "sloppy writing".[167] Theron Martin of Anime News Network criticized 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.[168] DeviceCritique explained that Sword Art Online influences the virtual reality market to grow, and referenced the Oculus Rift as a prime example of the starting point of virtual reality. It also praised Sword Art Online for exploring the psychological and social aspects of virtual reality gaming.[169]

While the anime received criticism in western media, the later light novel arcs, such as Mother's Rosario and Alicization, received praise. Anime News Network reviewer Theron Martin praised many of the volumes of the Alicization arc, saying that the author's writing had improved.[170] Martin also praised the anime adaptation of the Alicization arc, describing the opening episode as "about the best adaptation that could be hoped for of the relevant source material".[171]

Cultural impact[edit]

Kirito makes a cameo appearance in the eighth episode of the anime series Eromanga Sensei, with Yoshitsugu Matsuoka reprising his role.[172]

Steven Spielberg's 2018 film Ready Player One contains a reference to Sword Art Online.[173]Ernest Cline, the writer of 2011 novel Ready Player One, discussed Sword Art Online in an interview, noting how he met its writer Reki Kawahara at an event in Japan where they discussed how they independently developed similar ideas related to virtual reality.[174] It has also been noted that the Phantom Bullet (Gun Gale Online) arc released in print in 2010 depicts an early fictional battle royale game called Bullet of Bullets.[175]

On June 12, 2015, the now-inactive Chinese Ministry of Culture listed Sword Art Online II among 38 anime and manga titles banned in China.[176] In July 2020, Sword Art Online became one of seven manga titles to be removed from Books Kinokuniya in Australia for claims of promoting child pornography.[177]

In the 2020 edition of Kono Light Novel ga Sugoi!, Sword Art Online was voted by the public in an online poll and by a jury (critics, influencers, and other people related to the light novel industry) as the best light novel series of the 2010s, being the first in the ranking with 1,728.95 points.[178]

Kirito (キリト, Kirito) / Kazuto Kirigaya (桐ヶ谷 和人, Kirigaya Kazuto) / Kazuto Narusaka (鳴坂 和人, Narusaka Kazuto) (birth name)

Main article: Kirito (Sword Art Online)

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

As the main protagonist of Sword Art Online, Kirito was chosen to be one of the one thousand beta testers for the closed beta of Sword Art Online, the first ever Virtual Reality Massively Multiplayer Online Role-Playing Game (VRMMORPG) for the NerveGear, and later joined the official version of the game where he became one of the 10,000 players trapped in Sword Art Online. During the start of SAO, he befriended a girl named Asuna. During the 1st Floor Boss, as Illfang the Kobold Lord's weaponry and attack patterns differed from the beta, while the raid party relied on Argo's published beta test version of information about it, Diavel was killed by the monster while attempting to obtain the Last Attack bonus. Because of this, the hatred for beta testers resurfaced and threatened to go out of control. Kirito decided to end the tension by claiming that a majority of beta testers were inefficient and incapable players, while only a select few of the beta testers like himself resulted the creation of the category Beater and Kirito remained a solo player for majority of the game. For being the first player to defeat the 1st Floor Boss, Kirito received a black leather trench coat that becomes his trademark appearance for the rest of the series.

During the time Kirito spent in SAO, Kirito joined a guild named the Moonlit Black Cats, but he kept his character's level a secret, which resulted in the entire guild being killed by monsters, which led to Kirito wallowing in his despair and self-loathing until he read the time delayed message Sachi left for him on Christmas Eve. This event kept Kirito from joining another guild. Kirito befriended a girl named Silica and helped her revive her pet Pina. Later, Kirito met a blacksmith named Lisbeth, who forged a new sword for Kirito after he unlocked a unique skill: Dual Blades, although he kept it hidden to avoid attention. However, he was forced to reveal it during 74th Floor Boss fight in order to save the people nearby as they couldn't leave by teleport crystal and defeating the boss. Later he was forced to join the Knight of Blood Oath after the revelation of his unique skill and accepted the duel against Heathcliff for allowing Asuna to go with him and lost. He soon begin to develop a relationship with Asuna and later married her in-game. Later, Kirito exposed Heathcliff as Kayaba after the 75th Floor Boss. He faced him in a one on one duel with a condition; to allow every player to logout if Kirito wins, and manages to defeat him ending SAO with a total of 6,147 survivors.

Despite the completion of SAO, Asuna remains unconscious and Kirito learned from Agil that Asuna is trapped in another virtual reality called Alfheim Online. Logging into Alfheim Online to rescue her, where he meets a player name Leafa, who is unknowingly, is his younger sister Suguha; who agrees to guide him to the head toward to the top of the giant World Tree, in order to get to Asuna. Arriving there and tried to get to the top of World Tree, but rescue by Leafa where he soon learns Leafa's identity as Suguha where Suguha reveals her feelings for him in the real world. Not knowing how to respond or comfort her, Kazuto tells her he will be waiting for her in game. When they meet up they engage in a fight which culminates with both of them letting down their guard expecting the other one to kill them, however that only leads to them hugging and apologizing to each other. Leafa lets go of her feelings for Kirito and after pulling herself together Leafa helps him rescue Asuna from the top of the world tree.

Eventually Kirito manages to reach to the top of the World Tree and see Asuna again where he was confronted by Sugou going by Oberon, binding them both with gravity magic. Oberon then stabbed Kirito with his sword, and then critically damaging Kirito by increasing Kirito's pain limit and impaling him. When the consciousness of Akihiko Kayaba reminded Kirito how he was defeated by Kirito's determination and give him his admin ID and password and remove Sugou's GM status, Kirito then blinds and dismembers him after setting Sugou's pain limit to the maximum declaring the pain was much more painful in SAO compared to ALO. After rescuing Asuna, he soon receives a program from Kayaba called the World Seed which revitalizes the VRMMORPG genre, after Kirito has it upload by Agil on the Internet.

Several months later, Kazuto is recruited by Kikuoka to investigate a serial killer known as Death Gun, a "player" in the game Gun Gale Online. GGO players are being killed by him in the game, which has led to their deaths in the real world. Kirito enters GGO and meets Sinon, who believes he's a girl due to his avatar, but she later discovers his true gender. Despite so, she continues to help Kirito prepare for the next Bullet of Bullets, which is where Death Gun is subjected to appear. However when the two first meet, Kirito discovers that Death Gun is a former member of Laughing Coffin. The BoB began, and Kirito learns of Sinon's past. After most of the other players have been taken out, Kirito and Sinon team-up to devise a plan to take down Death Gun. Kirito deduces Death Gun's method of killing and faces him in a battle, winning. He warns Sinon to be careful as he logs out. Once he did so, he rushed over to Shino Asada's (Sinon's real life identity) house and saves her from the Death Gun killer on the reality side, Kyoji Shinkawa. The two reconvene with Kikuoka, who then also discover that there was one last person in the Death Gun group... Atsushi Kanomoto, otherwise known as Johnny Black, and the last known surviving member of Laughing Coffin.

Later, Kazuto agrees to work with the company Rath in testing out their new full-dive system, the Soul Translator. The STL reads the Fluctlights in the human brain and transports them to a highly advanced AI world, the Underworld. In the Underworld, Kirito has no memories of reality while he dives, and cannot take any memories with him when he exits. After explaining the job to Asuna and Shino, he asks Asuna to go to America with him in an effort to witness the true embarking of full-dive technology, which she agreed. However, they are ambushed by Johnny Black, who puts Kirito into a coma. After being diagnosed with brain damage, Kazuto is taken by Kikuoka and the Japanese government to the Ocean Turtle, a base out at sea run by Rath. There, they put him into a dive into the Underworld with his memories of reality intact in order to buy them time for them to treat his brain damage.

In the Underworld, Kirito grew up with his best friends Eugeo and Alice, and both him and Eugeo were tasked with the calling of cutting down the Gigas Cedar. However a trip to the End Mountains, resulted in Alice touching the Dark Territory, breaking the Taboo Index. Alice is subsequently taken away, and Kazuto awakens in reality. When he returns after his attack, he has his memories from reality intact and meets Eugeo. He helps Eugeo cut down the Gigas Cedar and the two depart for the Central Cathedral, where they both enroll in the Swordsman Academy in North Centoria. Several months in, the two prevent a rape on their pages and kill their abductors, which causes them to break the Taboo Index. The two are imprisoned, but escape and are saved by Cardinal, who gives them the skills and knowledge they need to take down the Integrity Knights, defeat Administrator, and fight the impending invasion by the Dark Territory. The two trek their way up the tower. They defeat Deusolbert, the Integrity Knight who took Alice away. They outsmart Linel and Fizel, the two youngest Integrity Knights. After defeating Fanatio, the two finally meet Alice, but Kirito and Alice are separated from Eugeo. After making his way to Quinella, Kirito is forced to fight Eugeo who had been corrupted to becoming an Integrity Knight. Kirito defeats him and returns him to his senses. However after a long battle with Quinella, Eugeo dies in Kirito's arms. Quinella attempts to escape to the real world by summoning a console that can contact Rath, but Chudeklin appeared and took her down with him, and they both perish. Kirito uses the console to contact Rath, but Rath was under attack, and Kirito's fluctlight became damaged.

Alice returned to Rulid Village with Kirito after the battle with Administrator, and took care of him. She notes that it was because of him, she hung up her sword. After the Dark Territory had begun their plans to attack the Human World, Alice is forced to go back to the front lines and took Kirito with her, leaving him in the care of Tiese and Ronye, who are both devastated to hear of Eugeo's death. He is later found and attacked by PoH during the Underworld War, but the memory fragments Eugeo left behind to him caused his fluctlight to be restored. Now awakened, Kirito forcingly logged out the remaining foreign players attacking Underworld and defeated PoH before going out with Asuna to rescue Alice.

She is forced to play the role of «Titania the Queen of Fairies», with Nobuyuki Sugou, the man responsible for imprisoning her, playing as Oberon, the Fairy King. This is done so that Sugou could marry Asuna in the real world, while she is unconscious and thus take over RCT Progress Inc.

When Yui's voice is heard, she throws the GM card down to her. Upon being released, she creates two avatars for Alfheim, Asuna (the Undine Healer) and Erika (and the Sylph battle character), and went on to continue living together with Kirito. She enrolls at the SAO Survivor School with Kazuto Kirigaya in the real world after everything ended. In the real world, Asuna's parents want her to follow in their footsteps. However, after living in SAO and meeting Kirito, she gains a different perspective and looks back on her past with disgust. She officially becomes Kazuto's real-life girlfriend and dreams of marrying him and having a family with him in the future.

Asuna becomes a major character in Alicization. After Kirito disappears off the grid after Johnny Black's attack, Asuna discovers the existence of the Ocean Turtle and requested the help of Rinko Koujiro, who helped her get on board and convinced Kikuoka to let her stay.

Originally a side-story character in SAO, Yui later becomes an accompanying/support character in ALO. At first thought to be a lost child in SAO, she is an artificial intelligence. Her full designation is «Mental Health – Counselling Program», MHCP version 1, codename, «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 amnesiac child whom they adopted. In the end she was nearly deleted by Cardinal, the management system of SAO, but is saved by Kirito 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 "Daddy" and Asuna as "Mommy" and gets very annoyed if any other girls try to flirt with Kirito, she also asserts Kirito not to keep any secrets from Asuna. Kirito uses his skills and resources in the real world to construct a device for Yui to view the real world even while she is in virtual reality and gives her the ability to communicate with them.

Very early in the game, she was able to tame a small dragon named Pina (ピナ), who is named after her real-life cat: this feat gave her immense fame, but she was just a mid-level player. Due to her fame, many tried to get on her good side, causing her to get a bit of an inflated head. She usually stays away from the males, who try to marry her (despite the fact that she's only 13) or make her their "mascot." After getting lost in a forest, Pina is killed trying to save Silica from a monster attack. Kirito rescued and helped Silica get the "Pneuma Flower", an item that can revive tamed beasts, as she resembled his sister. She gained feelings for him, but once she discovers his skills, she realized that they cannot be together in the game but promise to meet again. Keiko befriends Rika at SAO Survivor School.

Maybe it was [Ayahi] Takagaki's acting, but when I heard that her lines during that scene, I was like, wow."[7]

Heathcliff (ヒースクリフ, Hīsukurifu) / Akihiko Kayaba (茅場 晶彦, Kayaba Akihiko)
Voiced by: Tōru Ōkawa (Heathcliff), Kōichi Yamadera (Kayaba) (Japanese); Kevin M. Connolly (Heathcliff), Marc Diraison (Kayaba), David W. Collins (Kayaba; Alicization) (English)

Akihiko Kayaba is the director and creator of the NerveGear and Sword Art Online, as well as the main antagonist of the SAO arc. He traps all the players within SAO by using the NerveGear to obstruct signals from the user's brain. Any in-game death or attempt at removal of the NerveGear would result in the real-life death of the user. Later, it is discovered that he has been posing as Heathcliff, the leader of the Knights of the Blood Oath. Although he has the admin authority to make his avatar immortal, he is shown to be a powerful player even without his in-game immortality due to his intimate understanding of the SAO game mechanics which he himself had designed. His only goal in life was to make Aincrad a reality.

When his identity is exposed by Kirito, he challenges Kirito to a one-on-one duel where all of the remaining players will be logged out if Kirito is victorious. Following his defeat, he commits suicide by running a high output scan on his brain, but downloads his own consciousness into the server and leaves behind a program that gives Kirito the World Seed, which revitalizes the VRMMORPG industry.[30]

Richard Eisenbeis of Kotaku compared Heathcliff poorly to the series' second villain, Oberon, writing "How do you make a better villain than a man who trapped 10,000 people in a death game for no adequately explained reason? Easy. You just show how good that guy was by comparison to the new villain."[31]


PoH (プー, ) / Vassago Casals (ヴァサゴ カザルス, Vasago Kazarusu)
Voiced by: Tsuyoshi Koyama, Nobuhiko Okamoto (young) (Japanese); Xander Mobus (English)

PoH is the leader of the SAO "Red player" guild, Laughing Coffin. He created the guild for the sole purpose of killing other players. PoH stands for Prince of Hell and he worked as an assassin for a Korean mafia during this arc. He is an illegitimate child of a Mexican woman and a Japanese man under unknown circumstances and was forced to donate one of his kidneys to his father's legitimate son. This led to his hatred against Japanese people. PoH is the secondary antagonist of the War of the Underworld sub-arc and Alicization Arc who is under employment of Glowgen Defense Systems and loyal to Subtilizer. After PoH entered the Underworld, he captured Kirito and attempted to kill him with the broken Blue Rose Sword, but ultimately was defeated by Kirito after he regained his consciousness. And to ensure that PoH will never log out from the Underworld and come after him in the real world, Kirito turned PoH into a giant tree resembling Gigas Cedar (the tree Kirito and Eugeo managed to chop down in the past). As a result, Vassago's body in the real world aged rapidly. But when Critter and the rest of Subtilizier's minions collected bodies of their dead comrades before their escape, Vassago's body had mysteriously disappeared, leaving his full fate unrevealed.

PoH is most likely the real main antagonist of Sword Art Online in general, as well as being Kirito's archenemy.

Oberon the Fairy King (妖精王オベイロン, Yōsei-ō Obeiron) / Nobuyuki Sugō (須郷 伸之, Sugō Nobuyuki)
Voiced by: Takehito Koyasu (Japanese); Todd Haberkorn (English)

Nobuyuki Sugō is the main antagonist of the Alfheim Online arc. He is the one responsible for keeping 300 NerveGear victims, including Asuna, prisoner even after SAO had ended. He did this by transferring them all into ALO for experiments on human subjugation via fulldive technology. He also attempts to take over RECT Progress Inc. by marrying Asuna while she is unconscious. He displays a perverse interest in consummating this marriage while Asuna is still comatose. In ALO, he takes on the identity of Oberon the Fairy King and makes Asuna his queen, Titania. When he and Kirito finally meet, he flaunts his GM status as well as the results of his research by critically damaging Kirito by increasing Kirito's pain limit and impaling him. However unlike Kayaba, he is a poor fighter and he is defeated by Kirito when the consciousness of Akihiko Kayaba reminded Kirito how he was defeated by Kirito's determination, before aiding him in overcoming Sugō's GM status by using his Kayaba ID Heathcliff and removing Oberon GM Status. Kirito then blinds and dismembers him after setting Sugō's pain limit to the maximum. All 300 victims are released from ALO, but Sugō makes another attempt to attack Kazuto while he is making his way to Asuna in the real world, now blind in one eye and insane after his defeat. However, he is once again subdued by Kazuto, who puts the unarmed combat skills he had learned in SAO to useful effect and ends up cutting his neck. Sugō later survives the cut and is then interrogated for his crimes.

The character was lauded as an "excellent villain" by Kotaku's Richard Eisenbeis, describing him as "cowardly, fancies himself a god, and is torturing people just to make money. More than that, he is also constantly threatening to rape Asuna—both in the game and in the real world. Simply put, he has the greatest hallmark of a good villain: He is a guy you love to hate."[31] Responding to criticism of Oberon being an "over-the-top" villain that is "comically evil", Karen Mead of found to be partially true, writing "would the show be better overall if Sugou was a more subtle villain who didn't take every opportunity to be an absolute douche? Maybe, but keep in mind, as a show about online interactions, demonstrating The Greater Internet Dickwad Theory is definitely in SAO's purview. He may not be a great character who's going to make anyone's "Top Villains We Hate to Love and Love to Hate" list, but he's a villain that makes perfect sense within the context of SAO's world."[32]

Theron Martin of Anime News Network found Sugō's character to an "over the top villain" and "the second arc's biggest stumbling block".[8] However, Rebecca Silverman (also of Anime News Network) disagreed, writing "Sugou actually feels the least over-the-top as he plots how to use the VR technology for his own ends [when compared to the other characters]", and praised him as "nicely evil".[33]

He and his brother, a former member of the red SAO guild Laughing Coffin, used the Death Gun account to commit murder: Kyōji normally posing as Sterben and using a «Metamaterial Optical Camouflage Mantle» to spy on other players inputting their real life details so his brother can make his way to the house of a potential victim to inject the person with succinylcholine, a drug capable of stopping the heart, at the exact moment the victim's player is shot. During the Bullet of Bullets Tournament, the brothers switched roles while enlisting another Laughing Coffin member to assist them due to the multiple victims they selected.

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. Having been forced to bear the pressure of taking over his family's hospital while bullied at school, Kyōji was more fascinated with Shoichi's murderous exploits in SAO while becoming disillusioned with the real world. Kyōji finally snaps after a famous GGO player tricked him and multiple other newer players into creating weak, agility focused avatars knowing that there was going to be a patch that would give his strength focused character an edge in the upcoming Bullet of Bullets tournament. This resulted with Kyōji creating the Sterben account in XaXa's image and committing murders as Death Gun with the help of XaXa and Johnny Black. Kyōji is also revealed to be romantically obsessed with Shino, having Shoichi be Death Gun during the BoB so he can personally kill her in a murder-suicide and be "reborn" with her in a new world where their modern worries won't exist. But Kirito manages to save Shino and Kyōji is placed in police custody.

But in a departure from usual NPCs, Thrym is one of few whose core programming is connected to ALO's language engine to be a more realistic character. In the game storyline, Thyrm emerged from Aflheim and used the stolen Excalibur to conquer the Hill Giants' realm of Jötunheim. With Jötunheim turned to a frozen wasteland after losing the World Tree's blessing, Thrym created his fortress Thrymheim from the frozen spring of the Hill Giant leader Urðr, after its waters were lodged in the tree's receding roots. Thrym then uses his forces, and players he recruits on a false quest, to slaughter the native beasts to cripple the power of Urðr and her sisters so he can reach the surface of Alfheim and obtain the golden apple growing on top of the World Tree. But as Kirito and his party realize upon taking Urðr's quest to stop him, Thrym's actions would cause a chain of events that would result in the Ragnarok scenario and ultimately reset ALO. The group find Thrym and manage to defeat him with the help of a NPC named Freyja, who was revealed to be Thor in disguise.

She raised her stats to a ridiculously high level and decided to take control over the Underworld. Fooling people into believing she was a goddess, she created the Axiom Church and made laws to maintain the people to a certain degree. In the process, she tried to find a way to transcend the limit of that world, the «Life» of that world. She unlocks the forbidden System Control Authority command on the brink of death and immediately uses it to recuperate herself, restoring her beauty and «Life» to her former appearance as a youth. After being critically wounded in a battle against Kirito, she attempted to preserve herself by leaving to the real world but was intervened by the gruesome senate Chudelkin, who set his body ablaze to reach her.

The 10 Most Powerful Sword Art Online Characters, Ranked

Sword Art Online is packed with powerful characters - heroes and villains - but who is the strongest of them all?

Sword Art Online started as a series of light novels, and from there, became a massive phenomenon; the series now includes multiple seasons of the anime, as well as a feature film. The original story of Kirito and Asuna, players trapped in a full-dive video game where death has become real, has evolved - the days of being stuck in Aincrad are gone, but the world of VRMMOs in this universe has simply expanded. From the Nine Realms of New ALfheim Online to the Augma and real-life augmented reality, this universe is packed with complex and powerful characters - and these are the strongest of all!

RELATED: 10 Great Anime Featuring Strong Female Protagonists

10 Administrator/Quinella

From the latest season of Sword Art Online, the Administrator seems at first to be an all-powerful being within the world of Project Alicization. However, Quinella has more weaknesses than you might expect. At the start of her season, Quinella rules the virtual world with an iron fist - and so effectively that she is actually able to sleep most of the time, waking only to check on things. She understands the code of the virtual world perfectly, and is functionally immortal as a result. However, her attempts to expand her powers by transferring memory into the Cardinal becomes her downfall (plus, of course, annoying Kirito, which is a guaranteed way to end up killed).

9 Death Gun

One of many villains who have found a way to kill within the virtual world, Death Gun is the main villain of Gun Gale Online. As an incredibly powerful player and accomplished killer (who manages to take out several players over the course of this arc), Death Gun is another character who you might think would be deserving of a higher spot on this list. However, Death Gun was not a single player - but was revealed to be a group of killers operating under a single name. While still incredibly capable, this takes Death Gun from a seemingly impossible killer to simply a trio of murderers with a particularly well-laid-out plan.

8 Leafa

Kirigaya Suguha didn’t have a huge part to play in the original Sword Art Online, but since then, she has become an incredibly capable player. In ALfheim Online, she was the one who was able to teach Kirito the ropes, and was evidently extremely good at the game (let’s be honest, being able to teach Kirito anything is something of a feat in itself!). She is also one of the five fastest Sylphs in the game, as well as one of their best fighters, having won fighting tournaments in-game. In addition, when in the real world, she is also trained in Kendo, meaning that her strengths aren’t just online.

7 Sinon

Another character who has been able to teach Kirito a thing or two, Sinon is one of the main characters introduced in the Gun Gale Online series. She starts out as an incredibly capable player in this game, and has managed to get herself a rare weapon: a PGM Ultima Ratio Hecate II. With it, she is an incredibly accurate sniper, something that carries over to when she starts to play ALfheim Online, where she is an archer - and able to shoot arrows further than should be possible.

RELATED: Anime To Watch If You Like The Dragon Prince

However, she ranks so high on this list because of her inner strength - especially in the real world. After a childhood of trauma, she started to play GGO to deal with her trauma around guns, and facing her fears makes her stronger than any online ability could.

6 Alice

Another one from the newest season of Sword Art Online, Alice easily becomes one of the most powerful characters in this series. The original Alice is just a young girl with a talent for the sacred arts, but after she is turned into an Integrity Knight, she becomes epically powerful - and is able to take on Eugeo and Kirito together, after they have defeated the other Integrity Knights in their path. Alice also gets extra points for strength because of her ability to overcome the loyalty of the Integrity Knights, blow out her own eye, and take on Quinella - and for the strength taken to make her final sacrifice.

5 Oberon

Oberon, aka Sugou Nobuyuki, is the King of the Fairies, and one of the more diabolical villains of the Sword Art Online world (and there’s some stiff competition for that title!). Not only is he incredibly powerful within the original ALfheim Online (and is potentially one of the strongest players in-game), but he is one of the most powerful people outside the game, too. He is rich, greedy, and extremely smart, able to ‘kidnap’ the minds of three hundred people to use for his own experimentation. Oberon is the perfect example of someone who is powerful both in the virtual world, and in the real one.

4 Yui

Yui may be an AI, rather than a human, but any fan of this world will tell you that that doesn’t mean she isn’t a hugely important character in the world of Sword Art Online. Originally created as a mental health AI for Aincrad, Yui became the adoptive child of Kirito and Asuna, and has proved to be incredibly powerful - and useful - over the years.

RELATED: 10 Anime To Fill The Void After Game Of Thrones

Her status as an AI means that she has the ability to go into any of the virtual worlds and manipulate things no others could. She is also able to go into the guts of the game to find out the real-world locations of people that others couldn’t. Her lack of a body may slow her down, but that doesn’t mean that Yui isn’t one of the most powerful characters in this universe.

3 Asuna

Now we’re into the big three - and of course, Asuna has to be up here. One of the two main characters of this universe, Asuna is a particularly powerful player in her own right. In Aincrad, she rose through the ranks to become one of the highest ranking members of the Knights of the Blood Oath. Known as the Flash due to her incredible speed, she is one of the best fighters in the entire game. Later seasons don’t always do her justice, unfortunately, as she is kidnapped and held prisoner for most of ALfheim Online, and a lesser part of both GGO and Project Alicization. However, her abilities in the augmented real world in Ordinal Scale are incredible, and her sheer grit when it comes to finding Kirito in Project Alicization are phenomenal.

2 Heathcliff

The last villain on the list is also the original big bad of Sword Art Online: Heathcliff. Real name Kayaba Akihiko, he played as Heathcliff, the leader of the Knights of the Blood Oath, and was unbeatable in-game. Of course, this wasn’t because he was such a skilled player, but because he was secretly the creator of the entire thing. He designed NerveGear, the Cardinal System, and the Seed, and was the orchestrator of the entire death-game that was Aincrad. Not only is he incredibly intelligent in the real world, he is ruthless, capable, and one of the most unbeatable in-game players.

1 Kirito

Who else could get the number one slot? From the start, Kirito has always had the advantage over everyone else in the virtual world. Originally one of the beta testers for Sword Art Online, he has moved through this universe gaining almost unlimited power, and the kind of weaponry that would make any player jealous. No matter what game he plays, he becomes ridiculously capable almost immediately… with the exception of his appearance in Ordinal Scale, where he learned that real world fighting takes a little more than virtual battles do! However, overall, there can be no denying it - Kirito has the anime-protagonist power of being essentially unbeatable… but we love him for it anyway.
