List of Sword Art Online characters

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The following is a list of characters from the light novel, anime and manga series Sword Art Online. Most of the characters are introduced as gamers who play and consequently become trapped in a virtual reality massively multiplayer online role-playing game (VRMMORPG). The series chronicles their interactions in multiple online worlds: Sword Art Online (SAO), ALfheim Online (ALO), Gun Gale Online (GGO), and Underworld (UW).

Main characters[edit]







Heathcliff (ヒースクリフ Hīsukurifu?) / Akihiko Kayaba (茅場 晶彦 Kayaba Akihiko?)
Voiced by: Tōru Ōkawa (Heathcliff), Kōichi Yamadera (Akihiko) (Japanese); Kevin M. Connolly (Heathcliff), Marc Diraison (Akihiko) (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. He is destroyed by Kirito at the end of Volume 4, leaving behind a program that grants Kirito the World Seed. His death is his own doing since he has also rigged his own Soul Translator device to kill him when he is destroyed and transfer his soul into a digital form onto the Internet.[1]

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."[2]


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. He is destroyed when the "Ghost Program" of Akihiko Kayaba reminded Kirito how he was defeated by Kirito's determination, before aiding him in overcoming Nobuyuki's 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 Nobuyuki 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. Nobuyuki is then arrested and charged 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."[2] Responding to criticism of Oberon being a "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."[3]

Theron Martin of Anime News Network found Sugō's character to a "over the top villain" and "the second arc's biggest stumbling block".[4] 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".[5]

Death Gun[edit]

Sterben (ステルベン Suteruben?, German for "to die") / Death Gun (死銃 Desu Gan?)

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.

Red-Eyed XaXa (赤眼のザザ Akame no ZaZa?) / Shōichi Shinkawa (新川 昌一 Shinkawa Shōichi?)
Voiced by: Ryōta Ōsaka (ALO), Sōichirō Hoshi (GGO) (Japanese); Ben Diskin (English)
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.
Spiegel (シュピーゲル Shupīgeru?) / Kyōji Shinkawa (新川 恭二 Shinkawa Kyōji?)
Voiced by: Natsuki Hanae (Japanese); Johnny Yong Bosch (English)
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 bare 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.
Johnny Black (ジョニー・ブラック Jonī Burakku?) / Atsushi Kanemoto (金本 敦 Kanamoto Atsushi?)
Voiced by: Ryōta Ōsaka
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. But six months later, Atsushi returns and attempts to kill Kazuto and Asuna in the real world. Though arrested, Atsushi came close to killing Kazuto with a succinylcholine syringe.


Thrym (スリュム Suryumu?)
Voiced by: Iizuka Shōzō (Japanese); John Snyder (English)

The King of the Frost Giants and final boss of the Calibur sidestory, 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 (クィネラ Kwinera?)

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. She was given the sacred task of studying the Sacred Arts. Soon, she learned that by killing others, one's stats could be raised, so every night she snuck out and killed the animals of the forest, which would respawn everyday anyways. 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 control the people. She studied the Sacred Arts intensely, trying to find a way to transcend the limit of that world, the «Life» of that world. She finds the System Control Authority command on the brink of death and immediately uses it to heal herself, restoring her beauty and «Life» to her former appearance as a youth.

Secondary characters[edit]


Yui (ユイ Yui?)
Voiced by: Kanae Itō (Japanese); Stephanie Sheh[6] (English)

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 girl other than Sinon, Leafa or Asuna gets close to Kirito. 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.


Klein (クライン Kurainn?) / Ryōtarō Tsuboi (壷井 遼太郎 Tsuboi Ryōtarō?)
Voiced by: Hiroaki Hirata (Japanese), Kirk Thornton (English)

A friendly player that meets Kirito at the start of the game, who quickly befriends and learns the basics from Kirito. They go their separate ways shortly after when Kirito leaves for another town to power level, while Klein remains behind to help out his less experienced friends, although he is concerned for Kirito due to his solitude and recklessness. Klein uses a katana to fight and later becomes a leader of his own guild, Fuurinkazan. He regularly meets with Kirito and his friends and occasionally joins them in quests in ALO, especially after the release of the World Seed.[7]

In an interview with Sword Art Online author Reki Kawahara, he noted that Agil and Klein are both "very popular", and he wanted to write short stories centred around their characters.[8]


Silica (シリカ Shirika?) / Keiko Ayano (綾野 珪子 Ayano Keiko?)
Voiced by: Rina Hidaka (Japanese); Christine Marie Cabanos (English)

A side-story character in SAO. One of the rare beast tamers in the game. Very early in the game, she was able to tame a small dragon, 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. She joins Kirito and his friends in ALO right after they meet in the real world: they often go together in quests.

Sword Art Online girls (including Silica) 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."[9] In an interview with Haruka Tomatsu, Asuna's voice actor, she nominated Silica as her favourite character as she is "the kind of character I would want to have as a little sister."[10]

Silica was awarded 18th in a Dengeki Bunko character poll for their light novels.[11]


Lisbeth (リズベット Rizubetto?) / Rika Shinozaki (篠崎 里香 Shinozaki Rika?)
Voiced by: Ayahi Takagaki (Japanese); Sarah Williams (English)

A side-story character in SAO, who is a blacksmith with her own shop and takes great pride in her abilities. Lisbeth or "Liz" is a close friend of Asuna who recommended her to Kirito. Kirito commissioned Liz to forge a custom-made sword for him and accompanies her in a quest for the special ore required for the job. During the quest, she also develops feelings for Kirito. She is devastated when she finds out that Kirito is Asuna's crush. However, she finds some solace after Kirito thanks her for giving him a renewed determination to fight on and clear the game. She requests to be Kirito's exclusive blacksmith. Rika is almost very well teasing Asuna about her relationship with Kirito afterwards. At SAO Survivor School, she and Keiko get irritated when seeing Kazuto and Asuna together. Liz later becomes a regular player in ALO and frequently joins Kirito and his friends in quests and takes up the task of upgrading their equipment.

Sword Art Online girls (including Lisbeth) 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."[9] Yoshitsugu Matsuoka, the Japanese voice talent for Kirito, mentioned Lisbeth as his favourite character, since "Liz is really straight-forward and focused inside of the world of Sword Art Online, but then there was that scene when she learned that her best friend Asuna was in love with Kirito... Maybe it was [Ayahi] Takagaki's acting, but when I heard that her lines during that scene, I was like, wow."[12]


Yuuki (ユウキ Yūki?) / Yuuki Konno (紺野 木綿季 Konno Yūki?)
Sword Art Online character
First appearance Volume 7, Chapter 3 (Novel); Mother's Rosario Chapter 1 (Cameo, Manga); SII Episode 19 (Anime)
Created by Reki Kawahara
Voiced by Aoi Yūki <
Nickname(s) Absolute Sword

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 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."[9] She also features in promotional advertisements for a series of Umaibo puffed corn snacks by Namco.[13] 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."[14]

Yuuki was awarded fifth in a Dengeki Bunko character poll for their light novels.[11]
