List of Sword Art Online characters

Kirito ; / / (birth name) : 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 falsely claiming that a majority of beta testers were inefficient and incapable players, while only a select few of the beta testers were skilled like himself and were withholding important information from normal players in order to hoard the best resources in the death game. This resulted the creation of the category Beater (Beta Cheater) and Kirito remained a solo player for the 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. Later, he realizes he is in love with Asuna, who returns his feelings, and they marry 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, he meets a player name Leafa, who is unknowingly his younger sister Suguha; she agrees to guide him to the head toward to the top of the giant World Tree, in order to get to Asuna. After arriving there and trying to get to the top of World Tree, he is rescued by Leafa, but he soon learns Leafa's identity as Suguha while 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, but he is confronted by Sugou going under the in-game name Oberon, who binds 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 gives 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, who was about to be raped by Sugou, he soon receives a program from Kayaba called the World Seed which revitalizes the VRMMORPG genre. Soon after Kirito has it uploaded 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 begins, 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 does so, he rushes 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, to which she agrees. 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 Chudelkin 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. Asuna ; / : The main heroine of Sword Art Online and main protagonist of the seventh volume and the Progressive series (which tells the entire Aincrad Arc through her perspective), Asuna – who is 17 (born: 30 September 2007) – is a friend and later to be girlfriend and the in-game wife of Kirito in Sword Art Online and Alfheim Online. The 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 who play SAO and extremely attractive, she receives many invitations and proposals. Asuna is a strong-willed, and an accomplished player known in-game as "the Flash" for her extraordinary fast skills with the rapier. Later, she falls in love with Kirito and they marry in-game after saving him from being killed by Kuradeel. 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 soon after the death of Heathcliff. Despite the completion of SAO, Asuna remains unconscious 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 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. She attempts to escape the World Tree where she is imprisoned and manages to steal a GM card, and is caught, and sent back after two slime guards verify she is the captive. 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 is also a major character in Alicization. After Kirito disappeared off the grid after Johnny Black's attack, Asuna discovered 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. When the Dark Territory began their attack, Asuna logged into the Underworld under the super account, the Goddess of Creation, Stacia. ==Major characters==

Yui ; : 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. Leafa ; / : Suguha, also known as Sugu; she is in actuality Kazuto's cousin, as her mother had been raising her sister's child from a young age after his parents died from an accident, though neither Suguha nor Kazuto knew about this until later. She is a diligent worker and has been practicing kendo for eight years, partially to escape the loneliness and isolation in her life. After Kazuto Kirigaya (the name of Kirito in real life) gets trapped in Sword Art Online, she begins playing Alfheim Online as a Sylph in an attempt to try to understand him better, and it is at this time that she finds out they are cousins rather than siblings; She regularly plays ALO together with Kirito, Asuna, Silica, Klein and the rest of their group. Leafa, Lisbeth and Silica also feature as protagonists in the spin-off manga series ''Sword Art Online: Girls' Ops'', where they form a team with Kirito away on a study program and Asuna tied up in family affairs. Critical commentary . Leafa has received generally positive critical reception. Karen Mead of Japanator.com critiqued Suguha's character as "a fairly nuanced, sympathetic portrayal of someone falling in love with a blood relation due to an unfortunate set of circumstances, which is entirely different from the 'I love you, Oni-chan!', fetishism that we see all too often in anime [...] We get to know Suguha entirely too well for that", thus debunking criticism of "Suguha falling for Kirito [being] toxic, awful siscon crap". Noting that the focus shifts away from Asuna towards Leafa in the Fairy Dance arc, Anime News Network's Theron Martin wrote in a review that "Suguha's unrequited love seems more like a play meant to pander to 'Big Brother Complex' fans, though she does get some nice emotional development out of it and some very good scenes later on when the matter of her attempt to replace her misplaced love for Kazuto Kirigaya with Leafa's attraction to Kirito (who is also unknowingly her brother) blows up". Reviewing the spin-off manga Sword Art Online: Girls Ops, Martin praised it for Leafa's prominence in the storyline, and "while Suguha was a veritable co-lead for one story arc, she has now been relegated to that role in the franchise, too". Rebecca Silverman, also of Anime News Network, referred to Leafa as a "somewhat more interesting character" than Kirito, despite her crush on him being "annoying". She referred to her having "promise as a character" as one of the positive aspects of the third Fairy Dance light novel. Silverman, in a review of episode 15 – 25 in the Sword Art Online anime, went on to say that "Leafa shows more emotional strength as a heroine than Asuna ever did", and she "also stand[s] out as one of the more interesting, developed characters", due to not being overly reliant on Kirito. Silverman also found Kirito and Leafa's relationship to have developed more naturally than Kirito and Asuna's. In his ''Sword Art Online: Girls' Ops review, Theron Martin also wrote that "That the first such [Sword Art Online spin-off] manga would feature Silica, Lisbeth, and Leafa is [...] no surprise, as fans have clamored for the former two in particular to get more attention ever since they were first introduced". Nine years later, while at a post office, an armed robber attempted to shoot a pregnant woman, but lost control of the gun after Shino bit his hand. Afterwards, she shot him three times, killing him. Since that event, she developed a fear of guns, entering panic attacks whenever one is visible. As a result, she is bullied at school by her peers, with a finger gun being enough to trigger her phobia. To help ease her trauma, her friend Kyōji Shinkawa convinced her to play Gun Gale Online''. Known as Sinon in-game, her main weapon is the «PGM Ultima Ratio Hecate II» sniper rifle, which she earned after defeating a monster in a dungeon. Shortly before the Bullet of Bullets (BoB) tournament, Sinon encounters Kirito, deciding to help him after believing he is female due to his avatar. After Kirito's true gender was revealed, an angered Sinon attempts to leave him, but they meet again during the BoB. The two are confronted by Death Gun, who causes Sinon's PTSD to relapse when his weapon was revealed to be a Type 54 pistol, the same weapon she had used in the post office shooting. She is rescued by Kirito and the two escape, though she is afraid to attack Death Gun. With his help, Sinon overcomes her fear and the two defeat Death Gun. Afterwards, the two end the tournament as co-winners after Sinon kills them both with a «Gift Grenade». Upon exiting GGO, Shino is visited by Kyōji, who congratulates her on winning the BoB. However, angry at Kirito, he attacks her with intentions of raping and eventually killing her, revealing himself to be Death Gun's creator. Shino manages to resist his attack and escape, but is stopped by Kyōji before she could exit the house; Kirito arrives and fights Kyōji, the latter eventually being knocked out by Shino throwing her stereo at him. After the Death Gun incident, Sinon seems to have gotten over her fear and is moving on from the incident, no longer vulnerable to her classmates' threats of using a gun on her. In Agil's café, Shino meets Asuna, Rika, and Sachie Osawa, a woman who had survived the post office incident, who convinces her that she had saved her and her daughter's life. Sinon eventually decides to play ALfheim Online with Kirito and his friends. Yuuki ; / : One of the main characters from Volume 7. She was an Imp in ALO, she started dueling anyone promising an 11-hit Original Sword Skill (OSS) if she's defeated: due to her undefeated status she's given the title "Absolute Sword". Eventually Asuna fights her but loses. After the fight Yuuki asks her to help defeating the 27th Floor boss with her guild the "Sleeping Knights" in desire to etch all their names on the Monument of Swordsmen to make a memory. After certain events, which include the defeat of the boss it is revealed that Yuuki has HIV/AIDS and the guild members are patients in terminal state: to test the Medicuboid device, designed supposedly by Rinko Koujiro, in care for future patients. Yuuki forms a strong bond with Asuna, in reminder of her late elder twin sister Aiko Konno. With the time passing Yuuki's condition deteriorates and after she entrusts her OSS «Mother's Rosario» to Asuna before she dies peacefully in ALO, surrounded by over 1000 players from every tribe in the game, including her guild members, Asuna and her friends. Sword Art Online girls (including Yuuki) feature in a merchandise lottery by Bandai, where they are depicted in french maid clothing with cooking utensils, with Anime News Network humorously noting that they have "brought in a pretty penny for the franchise's creators." Richard Eisenbeis of Kotaku complimented Yuuki as a "powerfully human" character, writing "Like with the classic Beowulf, Yuuki finds her meaning and immortality in the written word. For her, having her name (and those of her soon-to-pass-away friends) on a virtual wall for all eternity is proof that she existed. To her, even that is enough." Yuuki was awarded fifth in a Dengeki Bunko character poll for their light novels. Eugeo ; : A young lad who was also Kirito's "childhood friend" along with Alice in Underworld. He has his memories of Kirito purged, along with the rest of his fellow villagers, but recovers them later on, to a certain degree. He has a strong desire to find Alice after she was taken away by the Axiom Church, and in order to do so, Kirito teaches him his "Aincrad-style" sword skills, taking the "Blue Rose Sword" as his primary weapon. Eugeo became Kirito's best friend and most loyal companion throughout his time in Underworld. Later, he breaks the Taboo Index to save his disciples who are almost raped by nobles who had a grudge towards him and Kirito, becoming the first AI fluclight to successfully break the "Seal of the Right Eye". As a result of their "crime", Eugeo and Kirito come into conflict with the Integrity Knights of the Church as they fight to save Alice and free the Human Empire from the tyranny of Quinella. After coming to a stalemate duel with Bercouli Synthesis One, Eugeo is captured by Quinella and turned into an Integrity Knight, becoming . Eugeo broke free from Quinella's control, but he was bisected after dealing a critical blow to her and dies in front of a devastated Kirito. Eugeo tags alongside a young Alice to the afterlife. Amid the struggle with PoH in the Alicization – War of Underworld-arc, Eugeo's spirit helps to restore a catatonic Kirito to full health, and continues to support him in his battles against PoH and Gabriel Miller. Eugeo was awarded sixth in a Dengeki Bunko character poll for their light novels. Alice ; : The mysterious girl who was Kirito's "childhood friend", along with Eugeo, in Underworld. She is captured and supposedly taken away to be executed by the Integrity Knights for breaking the law by "entering" the Dark Territory. Years later Alice contacted Kirito, in spirit form, as well as aided in Eugeo's healing, showing that she is still alive and remembered both of them. She also implored them to come and find her. It is later revealed that she had become an Integrity Knight in Volume 11 of the light novels. Her name as an Integrity Knight is . Having lost her childhood memories due to the Synthesis Ritual, Alice is initially cold and hostile towards Kirito and Eugeo. After Kirito reveals the truth about her former identity and the corruption behind Administrator's rule, Alice chooses to join Kirito and Eugeo in their battle to defeat Quinella. Though they are successful in killing Quinella, Eugeo lost his life and Kirito was left comatose. Worried for Kirito's safety after having bonded with him, Alice takes him with her to Rulid Village where she is reunited with her little sister Selka. Setting up residence in a small house on the village outskirts, Alice cares for the catatonic Kirito and grows highly protective of him. Inspired by Kirito trying to save her village's people despite his crippled state, Alice later participates in the war against the Dark Territory. She gets kidnapped by Gabriel Miller, but is rescued through the efforts of Bercouli, Sinon, Kirito and Asuna. She is then sent to the real world and taken into the protective custody of Rinko Koujiro. She is given an android body created in her likeness, and officially revealed to the world as the first Bottom-Up AI in a press conference organized by Rath. Alice was awarded fourth in a Dengeki Bunko character poll for their light novels. Mito ; / : An anime original character for the Progressive movies, Misumi is Asuna's classmate in middle school who consistently ranks number 1 in her school examinations. Although she looks like an impenetrable beauty and honors student to most students, she and Asuna regularly play video games after school on the roof after Asuna discovers that Misumi is secretly a hardcore gamer who participates in local tournaments. Misumi was a beta tester for Sword Art Online and goes by the name Mito in the game, and is the one who encourages Asuna to log in to SAO on the day of release so that they can play together. After the SAO players are trapped in the game by Kayaba, Mito and Asuna travel and train together in order to get stronger and eventually clear the first floor. However, due to an accidental encounter with a horde of pitcher plant monsters, Mito is forced to abandon Asuna in order to save herself, an act which she felt extremely guilty of. She later joins a party which takes part in the boss fight on the first floor and realizes during the fight that Asuna is also there and that she isn't dead. As Mito struggles to apologize to Asuna, Asuna reassures her that she wasn't wrong to do what she did after a pep talk by Kirito, and they join the fight with Kirito to defeat the first boss. When Asuna decides to follow Kirito up to the second floor, Mito bids her farewell and leaves with the other surviving participants of the boss battle. Her appearance in the main story becomes official after her return in the Unital Ring arc to help Asuna in the Unital Ring case while revealing she survived SAO during the events they went separate ways. Her original avatar in SAO resembles an old dwarf. ==Antagonists==

Heathcliff ; / : Akihiko Kayaba is the director and creator of the NerveGear and Sword Art Online, as well as the main antagonist of the Aincrad 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. 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." Responding to criticism of Oberon being an "over-the-top" villain that is "comically evil", Karen Mead of Japanator.com 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." Theron Martin of Anime News Network found Sugō's character to an "over the top villain" and "the second arc's biggest stumbling block". Death Gun ; / Death Gun is the main antagonist of the GGO arc, a player killer whose victims somehow die in the real world after being shot by his signature gun, a Type 54 "Black Star" he named «Death Gun». In reality, Death Gun's actual user name is Sterben and is an alternate account created by Kyōji Shinkawa in the image of his brother's SAO avatar. 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. ; / : :One of Laughing Coffin's elite members, Red-Eyed XaXa is a sadist who believed in PoH's principles as he became the red guild's second-in-command. In real life, Shoichi's father did not have any expectations for him due to him being frail and sick. After SAO ended, having met Kirito during the Inner-Area incident to neutralize Laughing Coffin, Shoichi aided in Kyōji's Death Gun scheme before he eventually starts playing GGO under the Sterben account. Shoichi entered the Bullet of Bullets tournament to prove his "true" killing ability to the rest of the world, only to be defeated by Kirito before he and his brother are arrested after the GGO arc. ; / : :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. His fate remains unknown, but it is most likely that he is still being charged as a minor due his age. ; / : : One of Laughing Coffin's elite members, Johnny Black is a cold-blooded killer who likes to play with his victims as he once suggested to XaXa and PoH to have a fight-to-the-death with their captives Schmitt, Caynz, and Yolko for fun. Sometime after SAO, Atsushi helped Shoichi and his brother in their Death Gun scheme and was the only member of their gang to escape arrest. Six months later, Atsushi returns and attempts to kill Kazuto and Asuna in the real world but failed and was subdue and arrested by the police. Atsushi came close to killing Kazuto with a succinylcholine syringe, but is himself severely wounded, as being stabbed through his leg with an umbrella by Kazuto. Thrym ; : The King of the Frost Giants and final boss of the Calibur side story, Thrym is an artificial intelligence that ALO's Cardinal System created from the actual Norse myth. 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. Quinella ; / : The true ruler of Underworld, the highest minister of the Axiom Church, and the main antagonist of the Underworld arc. 350 years before Kirito would enter the Underworld, Quinella was born. As a descendant of a wicked founder, she inherited unethical knowledge by studying the Sacred Arts intensely. Soon, she learned that by killing others, ones' stats could be heavily raised, so every night she would sneak out and kill animals, which would respawn everyday anyway. 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. With Quinella latched by Chudelkin, the two were soon engulfed by the flame and perished. Chudelkin ; : Chudelkin was a dwarf-like creature that served as the of the Axiom Church in Underworld, working directly under Supreme Priest Quinella.
