    Heroes of Aincrad 
https://static.tvtropes.org/pmwiki/pub/images/sao_crew.png
From left to right: (Back) Klein, Sinon, Leafa, Kirito, Asuna, Lisbeth (Front) Silica, Yui (Not featured) Agil, Alice
Initially composed of the SAO survivors that became Kirito's close friends, before expanding to other friends he meets along the way in other games. After the clearing of SAO, they primarily hang out in ALO and frequently party up to go questing.
  • Badass Crew: While few in number, they are composed of SAO and ALO's strongest players that far outstrip larger guilds and parties.
  • Badass Family: Kirito and Asuna are married in game and dating in real life, with Yui as their in-game daughter. Suguha/Leafa is Kirito's sister/cousin, everyone considers Silica to be their younger sister, and Yuuki is Asuna's surrogate sister.
  • Battle Harem: The crew is largely made up of an ensemble of girls interested in Kirito, and they are all Action Girls capable of fighting for themselves in whatever virtual reality they reside in. When needing to take on bosses, Kirito gathers them up and they all go to kick ass together. Though the Harem aspect is downplayed considering Kirito only has eyes for Asuna.
  • Because You Were Nice to Me: It is never outright stated, but it seems to be a reason why Kirito's Unwanted Harem (and Klein) follow him.
    • Klein: The first time they met was in SAO, where Kirito helped Klein out in learning the basics.
    • Asuna: The night before fighting their first boss, Kirito gave Asuna some cream for her bread.
    • Silica: Rescuing her from mobs, helping her revive Pina, and being a big brother to her definitely counts.
    • Lisbeth: Giving her a coat in the cold and saving her from a deadly fall definitely helped out.
    • Leafa: Kirito saving her from the Salamander PKers and later refusing to abandon her even when it opposed his interests.
    • Sinon: While it took quite long to earn her trust due to getting off on the wrong foot, Sinon developed a Fire-Forged Friendship after he goes to great lengths to rescue her from Death Gun, and comforted her when she confessed to killing someone in real life.
  • Cast Speciation:
    • Kirito and Klein are both sword users, but have polar opposite personalities, with Kirito being stoic and serious, while Klein is flamboyant and goofy.
    • In ALO, Asuna and Leafa both serve as support magic users, however Asuna is calm and mature, while Leafa is childish and impulsive.
    • Lisbeth and Agil both run shops as merchants and serve as tanks, but Lisbeth is mischievous and playful while Agil is responsible and mature.
  • Color-Coded for Your Convenience: Almost all of the core SAO gang have a color associated with them. Kirito (Black), Asuna (White and Red), Leafa (Leaf Green), Sinon (Cyan and Olive Green), Lisbeth (Pink), Klein (Red), Agil (Emerald Green), Yuuki (Purple), Alice (Gold and Blue), and Eugeo (Blue). The only exception is Silica who has variably been given Red, Blue, and Yellow, without any specific fixed color.
  • Crippling Overspecialization: In ALO their group is severely lacking in offensive magic users. Aside from Sinon, who is a ranger, everyone else uses melee attacks. While Asuna and Leafa only specialize in support magic like healing. This comes to bite them hard in the Calibur arc where they go up against a pair of bosses with one specializing in physical resistance and the other specializing in magic resistance, with the physical resistance one guarding the magic resistance one for the majority of the battle.
  • Damager, Healer, Tank: These roles are split over the party in ALO.
    • Damager: Virtually everyone who isn't Asuna, Leafa, or Agil serve as Damagers (Kirito, Klein, Silica, Sinon), and all of them aside from Sinon being melee damagers. Especially Kirito thanks to his overwhelmingly high DPS.
    • Healer: Asuna and Leafa are assigned to this role thanks to their races specializing in healing magic. Though both are capable of switching to Damager if need be.
    • Tank: Agil fits the role of Tank the best, but when he's not around Kirito or Klein typically pick up the role and take the brunt of the damage. Lisbeth also fills this role to a degree due to being the only shield user.
  • Family of Choice: Having fought and bled side by side as brothers and sisters in arms for two whole years, the Heroes of Aincrad can confide and trust in each other on a level closer than most blood-families in the real world, as most "normal" people (such as Asuna's cruel and unfeeling mother) refuse to regard them as anything more than kids who have played online games a lot longer than most people.
  • Fighter, Mage, Thief: While there aren’t many instances of trios forming in this group, one prominent trio that does match this trope is seen in Girl Ops comprised of Lisbeth (fighter), Silica (thief), and Leafa (mage).
  • Guest-Star Party Member:
    • Yuuki doesn't officially join up with the group in canon, but she does hang out with them for a considerable amount of time, especially after Asuna helped defeat the boss and Kirito hooked her up with a VR probe. Averted in the games where she's an official party member straight from the get go and permanently stays since she avoided her canon counterpart's unfortunate fate.
    • Kikuoka/Chrysheight occasionally goes questing with them, though whether or not they consider him a friend is another story.
    • Yuna provides assistance to them in Ordinal Scale, even directly aiding them in combat in the Final Battle where she shields them from a boss monster and tells Kirito what he has to do.
    • In Lost Song, after the conclusion of the main story line, Kirito offers to party up with Sumeragi who accepts and is seen attending the celebrations with the rest of the SAO main cast.
    • In Accel Worlds vs Sword Art Online: Millennium Twilight, the SAO characters meet and team up with the Burst Linkers from Accel World, with any number of them able to party up with the SAO gang.
    • The Fatal Bullet crew (The Player, Kureha, Zeliska, ArFa-sys, and Itsuki) are usually considered their own group, but are still good friends with Kirito's team and often hang out or party up with them for quests.
  • Guys Smash, Girls Shoot: While there's no shortage of girls who smash, the ones who shoot are exclusively girls (Sinon, Asuna, Leafa), while the guys (Kirito, Klein, Agil) are all solely close range melee users. Klein even explicitly stated he refuses to use magic.
  • Home Base:
    • In the real world, the gang use the Dicey Cafe (the Good-Guy Bar run by Agil) as a Local Hangout to meet up and discuss plans.
    • In-game, Kirito and Asuna's log cabin mostly serves this purpose in ALO, once they buy it in New Aincrad.
    • In Infinity Moment/Hollow Fragment, the gang uses Agil's Good-Guy Bar in Arc Sophia as one. It's where they all go to rest and recuperate, where they hang out when they aren't clearing the game, and even where they sleep with them all having private quarters upstairs. The vast majority of the Slice of Life cutscenes take place here.
    • Fatal Bullet has Kirito and Asuna's apartment in Glocken City, where they and most of their friends hang out. Lisbeth and Agil run their gun enhancement and appraising businesses out of it, and it's also where Asuna can use her Tailoring skill to make any outfits the player has brought her the designs for. Though the Player also has their own apartment where they and ArFa-Sys hang out.
  • Improbably Female Cast: Despite the general conception that There Are No Girls on the Internet, most of the main cast is made up of girls.
  • Intergenerational Friendship: The kids all get along well with Klein and Agil who are both adults.
  • Multinational Team:
    • In ALO their group features a very diverse selection of the races available in Alfheim. These include: Spriggan (Kirito), Sylph (Leafa), Undine (Asuna), Leprechaun (Lisbeth), Cait-Sith (Silica, Sinon, Alice), Salamander (Klein), Gnome (Agil), and Navigation Pixie (Yui).
    • The game adaptation further diversifies them by including: Imp (Yuuki), Gnome (Strea), Spriggan (Philia), Leprechaun (Rain), and Pooka (Seven). If one counts Memory Defrag Eugeo, Alice, and Premiere are actually the only human members of the group.
  • Only Known by Their Nickname: Almost all of are exclusively referred to be their gamer names even when others know about their real names. The only exceptions are Asuna who goes by her real name online and Leafa/Suguha who Kirito is used to calling by real name.
  • Out of Focus: After the Aincrad arc, most of the supporting members tend to take a backseat while Kirito and the newest Arc Heroine go up against the Big Bad.
    • In the Fairy Dance, while Kirito and Leafa team up in ALO to rescue Asuna, none of the group aside from Agil (who gets one episode) appear prior to the season finale, where they all have a reunion.
    • In Phantom Bullet, while the majority of the group are featured when Kirito and Sinon are dealing with Death Gun in GGO, they are mainly reduced to watching footage of the BoB tournament and gasping in horror at what they see. Asuna plays a slightly larger role than the others as she goes to Kirito's real life location to check on him.
    • Mother's Rosario focuses on Asuna's adventures with Yuuki, with everyone else (Kirito included) getting relegated to the background. Though Kirito (and Klein) do pop up a few times to give some assistance, while the girls accompany Asuna during her match against Yuuki and later when taking Yuuki's VR probe to sight see.
    • Averted in Ordinal Scale where the majority of characters get far more focus than usual, especially Lisbeth, Silica, and Klein. Only Leafa gets sidelined for most of the film, while Sinon plays a small role in the action.
    • In Alicization, Kirito gets trapped in the Underworld and firmly locked away from his friends, having only Eugeo for company, as he struggles to find a way back to the real world.
    • In War of the Underworld, Kirito himself takes a back seat due a combination of his Fluctlight being damaged to the point of comatose and his Heroic BSoD over Eugeo's death, where instead Alice and Asuna took over as the new leads. It took Higa attempting to fix Kirito's Fluctlight and Eugeo's memory fragment successfully interrupting his suicide attempt to force him back into the lead role again.
  • Ragtag Bunch of Misfits:
  • Sixth Ranger:
    • Leafa doesn't join the group until Extra Edition, where she finally meets Kirito's friends and gets accepted.
    • Sinon is introduced as a member after the Death Gun incident of the Phantom Bullet arc is wrapped up.
    • Yuuki doesn't really became a member in canon, as Asuna instead joined her guild the Sleeping Knights, but in the video game Lost Song she joins the group almost immediately after she meets Kirito and Asuna.
    • Alice joins the crew after the events of Alicization.
    • The game continuity also adds additional members like Strea, Philia, Rain, Seven, and Premiere.
  • The Team: While they are not an official guild, they frequently party up together, such as in the Calibur arc, these are generally the roles.
  • Team Pet: Pina the feathered dragon. While she's officially Silica's familiar, she gets along with most of the other characters, especially Kirito who has had a fair share of interactions with her.
  • Theme Initials: Lots of these in regards to their gamer names.
    • Three characters names begin with 'A' (Asuna, Agil, Alice), two with the letter 'K' (Kirito, Klein), two with the letter 'L' (Leafa, Lisbeth), two with the letter 'S' (Sinon, Silica). Including Yuuki that would mean two with 'Y' (Yuuki, Yui).
    • Holds true for their real names as well. The same three with 'A' (Asuna, Andrew, Alice), two with 'K' (Kazuto, Keiko), two with 'S' (Suguha, Shino), two with 'R' (Ryōtarō, Rika).
  • Token Adult: Agil usually fills the role. While Klein is an adult too, the way he acts makes him One of the Kids.
  • Token Non-Human:
  • True Companions: The best of friends who treat each other like family, this is especially the case for the SAO survivors who are drawn together.
  • Twofer Token Minority: Agil is both the only one who isn't native Japanese and one of the adults in a group of teens.
  • Unwanted Harem: Specifically Kirito's Harem, due to Kirito's uncanny ability to attract girls, leading the male-to-female gender ratio to get bigger and bigger with each passing season.

Main Characters

For characters with their own pages see the following:

    Yuuki Konno / Yuuki 

Yuuki Konno / Yuuki (ALO)

Voiced by: Aoi Yuuki (Japanese), Erica Mendez (English), Eva Andrés (European Spanish), Amanda Hinojosa (Latin American Spanish)

https://static.tvtropes.org/pmwiki/pub/images/character_24015.png
Click here to see Yuuki (spoiler) 

"There are things you can only share with someone by fighting. For instance, how serious you are."

The deuteragonist of Mother's Rosario (Volume 7) and the energetic, cheerful Imp leader of the Sleeping Knights guild. She holds a street duel competition, hoping to find someone strong enough to help her guild solo a floor boss, an achievement which will mark their names on the Monument of Swordsmen.


  • The Ace: A VR prodigy and combat genius, being the only player able to best Kirito in combat. She earned herself the honor of World's Best Warrior for Alfheim Online.
  • Action Girl: She’s better at combat than Kirito, for starters!
  • Adaptation Relationship Overhaul: In the game continuity, she's a lot closer to Kirito who also directly gets involved in the Mother's Rosario arc adaptation, in contrast to canon where she mainly got close to Asuna. They even end up Like Brother and Sister just like she sees Asuna as a Cool Big Sis.
  • Adaptational Attractiveness: While she's fairly attractive in the web novels, she's even more prettier and sexier in other adaptations. This only applies to her ALO avatar, however.
  • Adaptational Early Appearance:
    • In the canon series, she doesn't appear until after GGO is introduced during the Phantom Bullet arc. In the video game continuity she has a brief Early-Bird Cameo as a Post-Final Boss in Hollow Fragment before appearing for real in Lost Song where the Mother's Rosario adaptation happens earlier than GGO.
    • She shows up even earlier in Integral Factor, appearing as early as Floor 4 as opposed to Floor 100. She also seems to have been drawn into the game the same way as Leafa did, having her ALO avatar with its Fairy features.
  • Affectionate Nickname: Her older sister calls her "Yuu."
  • All of the Other Reindeer: She was socially ostracized because of her having AIDS.
  • Always Someone Better: Duels with Kirito twice and wins both rounds. It is debatable (in-universe even!) who is actually more skilled, as Kirito never fights her with his signature style (and Lisbeth theorizes that Kirito never fights "seriously" anymore unless lives are on the line, and thus didn't go after her the way he did with Heathcliff and Death Gun), but her reaction speed and VRMMORPG experience are significantly better than his. Kirito even stated that had she been in SAO, the system would have instead granted her the dual blades ability due to her superior reflexes.
  • Always with You: She lives on in the OSS she gave to Asuna before she died. Her spirit even appeared to Asuna to help her against the Final Boss in Ordinal Scale.
  • Ambiguously Bi:
    • She shares a Romantic Two-Girl Friendship with Asuna in Mother's Rosario and drops several hints of it her love for Asuna being more than platonic, jokingly stating she would be up for marrying Asuna one day.
    • In the gameverse continuity, she is practically a member of Kirito's Unwanted Harem, even sharing a few pillow talk scenes with him (though they view each other more Like Brother and Sister. Though she also has even more suggestive moments in Hollow Realization developing a Romantic Two-Girl Friendship with fellow Genki Girl Strea and presenting a bouquet of flowers to Asuna in one event.
    • Integral Factor drops the ambiguity and has her outright confirming she desires to marry a woman someday, in addition to the usual teases like wondering if she and Kirito were love rivals for Asuna’s heart, or saying she loves Lisbeth and spontaneously hugging her after the latter makes her a sword.
  • Angsty Surviving Twin: Averted for the most part, but shows hints of this when she gets strongly attached to Asuna due to her resemblance to her twin sister.
  • Arc Hero: For the Mother's Rosario arc alongside Asuna.
  • Attack! Attack! Attack!: Her favorite strategy is to charge right at an enemy and fight them head on.
  • Attention Deficit... Ooh, Shiny!: It's more apparent in the games, however Yuuki at times can get easily sidetracked from whatever task she's performing at hand, such as chasing after a butterfly while she's on a quest to retrieve honey.
  • Badass Adorable:
    • She's a kind and cheerful little girl, but is also the most powerful player in the game and the only person who can beat Kirito in a fair duel.
    • In Lost Song and Hollow Realization, this character trait is amplified by the simple fact that she is living life to the full, no longer shackled by an impending death. She now plays and has fun just as any normal girl would, albeit she does so in the virtual world.
  • Badass in Charge: Yuuki is the guild leader of the Sleeping Knights, an already badass guild who took down a floor boss. While Yuuki herself is the World's Best Warrior of Alfheim Online.
  • Best Friend: Memory Defrag indicates she has become this with Leafa (while thinking of Asuna as a surrogate sister). She and Leafa are Birds of a Feather being the two fastest players in ALO and love of rushing into the action without any planning.
  • Beware the Nice Ones: When she was being denied access to the Floor 27 boss, she responds by trouncing one of the grunts blocking the way.
  • Big Brother Worship: In the game continuity she has this relationship with Kirito, where she remarks she gets a feel for what it's like to have a big brother.
  • Big Eater: Certain gameverse instances show Yuuki has a voracious appetite, able to wolf down food at high speeds.
  • Big Sister Worship: She looks up to Asuna as a role model and a surrogate sister. She evidently had this relationship with her late real twin sister as well. Particularly notable in that Yuuki is one of the few characters Asuna doesn't address using honorifics, which highlights just how close the two of them are.
  • Birds of a Feather: With Strea during the events of Hollow Realization, with both of them being so upbeat and cheerful they practically rebound off each other to the point where Asuna wonders if she's actually being a burden on Yuuki, until Yuuki presents her with a bouquet of flowers Strea helped her with in order to thank Asuna for her help on a real-world test.
  • Blade Spam: Her Signature Move is the Mother's Rosario, which is an 11-hit Original Sword Skill.
  • Blood Knight: Yuuki loves a good fight and is all too eager to challenger strong players to see how she fares against them.
  • Bokukko: Refers to herself using the personal pronoun "boku" as part of her tomboyish personality.
  • Breakout Character: Yuuki is insanely popular among the fanbase, for being the only character to be a challenge to Kirito along with her eternally cheerful disposition. Fans were utterly distraught she was Killed Off for Real at the end of her arc. However, through sheer Popularity Power she was able to be spared her fate in the game adaptations. She also gets a side story titled Sister's Prayer all to herself which covers her life before she met Asuna.
  • Casting Gag: Yuuki is very similar to another one of Aoi Yuuki's character, Hibiki from Senki Zesshou Symphogear. Both are energetic genki girls who are always ready for anything and both are inflicted with a condition that will soon kill them. Unfortunately, while Hibiki is eventually cured of her condition, Yuuki isn't so lucky...
  • Character Development: At the beginning of Sister's Prayer, hardly as upbeat or optimistic as she is by the time of Mother's Rosario, but by the end, she's on the way to founding the Sleeping Knights.
  • Color Motif: Heavily associated with purple, as part of her Purple Is Powerful theme. Her in-game avatar's hair is purple and all of the outfits she wears has the color to some degree.
  • Contrasting Sequel Protagonist: The first female lead whose story arc has almost nothing to do with Kirito, instead revolving around Asuna. She also breaks the trend of the female character being second best to Kirito, with her proving to be stronger than Kirito straight from the start.
  • Dark Is Not Evil: Is an Imp and wears mostly dark colors but is perpetually cheerful.
  • Defeat Equals Friendship: Yuuki earns the respect and friendship of everyone she crosses blades with by defeating them. Asuna, for instance, became her surrogate sister after their duel.
  • Deuteragonist: Of the Mother's Rosario arc. In the anime, she takes over the Evolving Credits opening during the arc.
  • Distaff Counterpart: To Kirito. Both are VR prodigies with natural talent, are Master Swordsman who became the World's Best Warrior for a VRMMORPG and end up as rivals to a degree, as well as both of them being associated with dark colors.
  • Do Not Go Gentle: Her main motivation for wanting to carve the names of the Sleeping Knights onto the Monument of Swordsmen before AIDS claims her and the rest of Sleeping Knights also pass on.
  • Doomed by Canon: Averted in the video game canon, as Yuuki doesn't die.
  • Duel Boss: After fulfilling certain conditions in Hollow Fragment, Kirito can challenge her to a non-fatal duel after beating Heathcliff. Despite the fact that she came from Alfheim Online, she instantly masters the mechanics of SAO to the point of giving Kirito a run for his money.
  • Early-Bird Cameo: She made her first voiced appearance in Hollow Fragment, months before the second season of the Sword Art Online anime aired.
  • Establishing Character Moment:
    • Her very first appearance has her issuing a challenge to all players in ALO where she proceeds to win 77 consecutive duels (including against Kirito). There's also the fact she's been nicknamed Zekkennote . She then fights Asuna and we get to see how she managed to beat everyone, with her showing an impossibly fast speeds in one of the most spectacular battles in the series. Then she unleashes her OSS, the 11-Hit Mother's Rosario!
    • In Integral Factor, she makes her presence known by pulling a Big Damn Heroes and helping out the Player, Koharu, and Kizmel when they get attacked by Fallen Elves.
  • Four Is Death: Her funeral was held on 04/04/2026.
  • Fun Personified: Yuuki believes in living life to the fullest. Knowing how little time she has left she treats everyday like it's her last and is always out to have a blast.
  • The Gadfly: In the game adaptation, she enjoys playfully teasing and messing with Kirito as she loves seeing his reactions.
  • Genius Bruiser: Yuuki isn't just a master swordswoman, but she's very talented academically and artistically. She calls herself a reader, and was once commended by Asuna to be good at Japanese at school.
  • Genki Girl: Aside from her superb combat skills, Yuuki is best known for her eternal sunny disposition, always out to live life to the fullest and have a good time.
  • The Gift: Yuuki is stated to be a combat genius. She's able to master techniques in one go, and even managed to develop her own 11-hit OSS on her own.
  • Godlike Gamer: Yuuki is probably the only character to qualify for this better than Kirito, fitting as she is his Distaff Counterpart. To date she's the only player able to best Kirito in a fair fight. Yuuki's VR talents are unparalleled as she practically lives and breathes the virtual world. She arrives in Alfheim Online and immediately wins 77 consecutive duels. She also created her own 11-hit Original Sword Skill which is stated to be a very difficult task.
  • Good Counterpart: For Shouichi Shinkawa / Red-Eyed XaXa . Both are very ill in real life and wanted to prove their strength in the VR world, which gave them more opportunity than the real world. Unlike XaXa, who completely gave up on the real world ethics and became a killing machine and Serial Killer as "Death Gun", Yuuki chose to become one of the best players in Alfheim Online and lead a band of similarly terminally-ill patients as well as being one of the genuinely nicest characters in the series.
  • Hair Antennae: She has a small one pointing near her headband. Ironically, she says she doesn't like bugs.
  • Hero of Another Story: She and the Sleeping Knights had many adventures in lots of other games before playing ALO.
  • Honorary True Companion: She doesn't officially become a member of the core SAO gang in canon, but she still became an exceptionally close friend to them, especially Asuna. Averted in the games where she's a literal True Companion.
  • I Knew There Was Something About You: Even after trying to cut all contact with Asuna so she wouldn't find out the truth about her, she had a feeling Asuna would find her in the real world.
  • Idiot Hair: Has one strand that always stick up, though she's far from an idiot, being shown to be a Genius Bruiser who is academically gifted.
  • Image Song: She has a total of three: "Liberty Rosario", "Sora e to Ateta Tegami" (a duet with Asuna), and "Sleepless Legend" (along with Asuna and the rest of the Sleeping Knights).
  • Ill Girl: She was born with HIV, contracted from an infected blood infusion given to her and Aiko's mother while giving birth to them. By the time Asuna sees her physical body, it was already blind, bedridden and on the verge of death, with her consciousness hooked up onto the Medicuboid for three years.
  • Irony: She is the strongest warrior in the game, but a bedridden, dying girl in real life.
  • Kill the Cutie: She was on the verge of being the fan-favorite of the series with her upbeat personality and impossible strength, but then it's revealed she's terminally ill with AIDS. She does not survive to the end of the story.
  • Leitmotif: "Light Your Sword", which "Light Your Sword", which she shares with Asuna.
  • Leotard of Power: A purple-black one, although it's a little hard to see under her dress.
  • Laser Blade: In Fatal Bullet she can wield a photon sword just like Kirito.
  • Lightning Bruiser: Remember how most opponents can't even react to Kirito dashing towards them before it's too late? Let's just say that Kirito can't even react to her and leave it at that.
  • Like Brother and Sister: In the game continuity, she develops this relationship with Kirito:
    • In Hollow Realization, Yuuki loves teasing Kirito to get reactions from him much like a little sister would. One of Yuuki's pillow events even has the two of them having a tickle fight.
    • In Fatal Bullet, Kirito piggybacks an exhausted Yuuki back home, where Yuuki remarks she now has the chance to know what it feels like to have a big brother.
  • Littlest Cancer Patient: Aged fifteen and terminally ill with AIDS which had already claimed all of her family. Though her time is limited, she lives life to the fullest and is an unbelievably strong person in the virtual world where no one was able to beat her. In the end her disease was the only thing allowed to claim her life.
  • Master Swordsman: She is called "The Absolute Sword" for a very good reason; even Kirito, the World's Best Warrior of SAO, was outclassed by her in single-sword combat.
  • Meaningful Name:
    • Her guild — "Sleeping Knights" may sound romantic, until one realizes that all its members are terminally ill patients with their consciousnesses kept alive by the Medicuboid while their physical bodies are sleeping, and are soon to be, figuratively, asleep for good.
    • Her own name, Yuuki: is a pun on the Japanese word "Courage", quite symbolic of her resolve to optimistically live her life with what little time she has left.
    • The character choice in her name also signifies that she was born when the crinum blooms, in July.
  • Nice Girl: A bright and kind-hearted lass who encourages everyone around her to happily live life to the fullest, without a single spiteful or selfish bone in her body.
  • Not So Invincible After All: As powerful as she is as Zekken, having never lost a single battle, she succumbs to her AIDS and loses her lifelong struggle against said disease.
  • Not Too Dead to Save the Day: Despite her death, Yuuki's spirit appears during the final battle of the Ordinal Scale movie to help Asuna and her friends.
  • Oh, Crap!: When she realizes that Merida is using Ran's NerveGear to try to get into Sword Art Online and help her guildmates, she panics.
  • One Steve Limit:
    • Yuuki's first name is pronounced the same way as Asuna's surname, which causes confusion when Asuna's friends refer to her as "Yuuki-san". When Yuuki jokingly suggests marrying Asuna, she suggests that Asuna should marry into her family as otherwise her name would be "Yuuki Yuuki".
    • In Memory Defrag, one event had Asuna's real name being the same as her gamer name being brought up. Yuuki asks why she didn't change her name when she moved to ALO, suggesting she could have gone with her last name "Yuuki", only for Asuna to point out that would mean their names would be the same.
  • Online Alias: Yuuki, the same as her real given name.
  • Pint-Sized Powerhouse: She is shown to be shorter than Asuna by a good bit, is only as old as Silica, but displays her prowess as the best player in ALO.
  • Plucky Girl: Twenty players blocking the entrance to the boss room, with thirty more on the way? Bring it on, she says.
  • The Pollyanna: Despite her family being killed off one by one by AIDS until she was left to bear the pain and the stigma by herself, she remains cheerful and as energetic as an Ill Girl could possibly be.
  • Post-Final Boss: In Hollow Fragment, with her appearance likely being due to the same glitching that brought Leafa and Sinon in. She appears only if Kirito chooses to investigate the optional "strange area" after defeating Kayaba, and should you do so, she and Kirito fight a Half-Loss Duel. Defeating her will allow her to be recruited into the party on a New Game+. However, as this event is directly referenced in Lost Song by both of them, the fight is canon in the videogame continuity.
  • The Prankster: Hollow Realization adds this side to her, where she loves messing around with Kirito for her amusement, such as scaring him when he's lost in thought or tickling him when he's trying to sleep.
  • Purple Is Powerful: She is the best player in ALO and a large portion of her attire is purple along with her hair.
  • Rapunzel Hair: Much like Asuna, her avatar's hair nearly reaches her waist. Though unlike Asuna this doesn't extend to her in real life.
  • Red Baron: In ALO, she is known as Zekken, or 'Absolute Sword', due to her legendary skill as a swordswoman.
  • The Rival: To Kirito, or the closest he has to one, being the one Worthy Opponent Kirito can't beat and Yuuki will never let beat. This is especially prevalent in the gameverse where the two frequently duel to determine who is better.
  • Romantic Two-Girl Friendship:
    • Shares one with Asuna. While milder than other examples, she lampshades this when she playfully proposes marriage to Asuna. Lost Song and Hollow Realization just adds on the subtext with Asuna getting depressed when she thinks she's becoming a burden on Yuuki's happiness and capped off with Yuuki giving her a bouquet of flowers to show how grateful she is for her help.
    • Memory Defrag has Leafa as Yuuki's best friend, with the two of them being the two energetic speedsters among the core group.
    • In Hollow Realization she starts to build one with Strea due to their shared enthusiasm and go-lucky attitude, to the point it triggers Asuna to wonder if her own friendship is just burdening Yuuki.
    • In Integral Factor, Yuuki forms one with Lisbeth, after becoming her client in making an extraordinary sword.
  • Samurai: In Sister's Prayer, she takes this as her Prestige Class once she gains a few levels in "Asuka Online."
  • Samus Is a Girl: In Season 2 Episode 18, as Liz and the others tell Asuna about Zekken, a mysterious warrior who always challenges people in a certain spot during a certain time of day. Asuna at first assumes that it's a guy, particularly as Kirito was also unable to beat him. Then in episode 19 she finds out that Zekken is actually a girl, and her image of a heavily armored man gets shattered. She also gets a little upset at Liz for not telling her Zekken was a girl and at Kirito as she suspects he lost on purpose because Zekken was a girl, despite him trying to say otherwise. She quickly learns that he was being honest when Yuuki counters her Quadruple Pain, showing just how fast her reaction speed is compared to Kirito's.
  • Saying Too Much:
    • In Sister's Prayer, she admits to Merida that she isn't using an Amusphere, almost spilling the beans on the Medicuboid test, which is meant to be confidential. Luckily for her, Ran lies to Merida and says that they're actually using modified NerveGears approved by their doctor.
    • Downplayed, but when Asuna tells her she called her "sis" twice, she breaks down crying because she and the Sleeping Knights don't want Asuna to get to close to them because they feel it will only hurt her if she learns about how they don't have much time left.
  • Signature Move: The titular Mother's Rosario, an 11-hit attack developed with pure skill in technique and crystallized into a Sword Skill. She later passes it on to Asuna before dying.
  • Spared by the Adaptation: In the non-canon game Lost Song, Yuuki's condition improves and she says that she'll be able to stay in the long run. Presumably, this is so that Yuuki (who becomes playable in said game) won't have to be cut out altogether. This continues into its sequels where Yuuki is ready to tackle new adventures with her friends and any worries about her condition are almost nonexistent. Yuuki lampshades this by saying that up until recently, she'd been told that she only had three months to live. See Your Days Are Numbered.
  • Stepford Smiler: She admits that she's not as cheerful or upbeat as she seems, and that it took her a long time to understand what her mother wanted to teach her by talking about Jesus, but believes that smiling and living life to the fullest are good things in and of themselves.
  • Strong and Skilled: She boasts the feat of winning 77 consecutive duels, as well as the only player to best Kirito in combat. This is attributed to her full diving 24/7, therefore having more virtual experience than anyone else (including SAO survivors). Even entering a new game, she's so familiar with the mechanics that it's second nature to her, and quickly usurps whoever previously held the title of strongest player. She has specifically been called a combat genius and can master techniques in one go. Proof of her skill comes from her developing the 11-hit Original Sword Skill Mother's Rosario.note 
  • Super Reflexes: Remember how we said that Kirito has the fastest reaction speed in SAO? Yuuki's reflexes surpasses even that. Kirito even said that had she been in Aincrad, she would have been the one granted the Dual Blades skill instead.
  • Swapped Roles: In Memory Defrag, the "Asuna's Great Adventure" event had Asuna being turned into a kid, which leads Yuuki to take up the role of big sister, whereas that was usually Asuna's job. Yuuki finds out it's not all fun and games. Kid Asuna proves to be a handful when she wanders off to do dangerous quests on her own, forcing Yuuki to constantly watch out for her and keep her safe.
  • Sweet Tooth: Yuuki has a fondness for sweet food, which matches her sweet personality.
  • Sword and Gun: In Fatal Bullet, she wields a photon saber and a Beretta 93R machine pistol simultaneously.
  • Talking Through Technique: She believes in facing others head on, and the fact that actions speak louder than words.
    • Her quote above is what she tells Asuna when they go up against a rival guild as being an ideology she lives by.
    • In Sister's Prayer, this is how she convinces Merida not to try to re-enter SAO in an attempt to help her guildmates.
  • Tomboy and Girly Girl: With Asuna. She'd much rather run around outdoors swinging her sword while speaking with a very boyish mannerism, in contrast to Asuna who was raised to be elegant and ladylike.
  • Tomboy with a Girly Streak: Kirito brings this up in Hollow Realization, noting that while Yuuki was a little tomboy she also had a girly side to her like a love of butterflies and knitting.
  • Too Good for This Sinful Earth: A shining beacon of courage, joy and hope too bright to remain burning in this cruel and selfish world.
  • Tragic AIDS Story: The Mother's Rosario arc is all about her struggle with AIDS.
  • V-Sign: Her signature Victory Pose, as seen here.
  • Weapon of Choice: Favors swords, much like Kirito. In Fatal Bullet she even picks a Photon Sword just like him.
  • Weapon Tombstone: Her sword, adorned with her bandana, marks the spot where she met Asuna for the first time as well as where she spent her final moments in the company of Asuna, her surviving guildmates, and Kirito and Asuna's raiding party.
  • Wolverine Publicity: In Integral Factor, Yuuki is featured as one of the main NPCs despite this being long before her canonical appearance. She doesn't even have the excuse of being adapted into the gameverse version of the Aincrad arc like Leafa and Sinon, as she only had an Early-Bird Cameo and was introduced in Lost Song the Alfheim Online adaptation. The only reason she's in the mobile game is because of popularity.
  • World's Best Warrior: Of Alfheim Online; even Kirito, the World's Best Warrior of SAO, respectfully acknowledges her as such.
  • Worthy Opponent: She and Kirito see each other as this, with no one else able to challenge either of them as much as the two of them do. They have had several duels in the game continuity with all of them being very close matches.
  • Your Days Are Numbered: In the gameverse continuity, despite making a near-miraculous recovery from AIDS, Yuuki herself believes that the disease is eventually going to get the last laugh. Her recovery has bought her at most two decades, which would be long enough to fall in love with someone, get married, and have kids, but not long enough for her to see her grand-children. Fatal Bullet sees her condition stabilize and she might even be cured through long term treatment. Fans are more than a bit paranoid that she could suffer a relapse.

"Love... is not something to seek out... it is something to give."

The deuteragonist of the Alicization arc, after Kirito. A boy who is a resident of the Underworld from Rulid Village who was a childhood of Kirito and Alice. His Sacred Calling is to cut down the Gigas Cedar, the seventh generation woodcutter since his predecessors. After Kirito helps him to complete said task, the two of them set out to become Swordsman.


  • Abusive Parents: His parents, particularly his father Orick, were of the emotional and neglectful variety. His father vastly preferred his older sons over Eugeo, often spoiling them while giving Eugeo flack for things that were either partially his own fault or outside of the young boy’s control. When Eugeo got his calling as Cutter of the Gigas Cedar, which is considered by pretty much everyone in Rulid as an honorable and praise-worthy calling, Eugeo’s parents, instead of congratulating him were openly disappointed because it cost them an extra hand on the farm. To add insult to injury, Orick took all the money Eugeo earned for himself, leaving his son with only enough to buy subpar bread and water for lunch while other kids were allowed to freely spend what they got, which served to increase the bullying he received from boys like Jink. It’s also implied that they, like almost the rest of Rulid, took part in the mass shunning of Eugeo after Alice’s arrest due to his association with her instead of comforting him over the loss of his Only Friend. This more than likely contributed to Eugeo’s skewed definition of love and made him more susceptible to Quinella’s manipulations.
  • Adaptation Dye-Job: Eugeo's eyes are green in the light novels and anime while the games gave him blue eyes.
  • Adaptational Attractiveness: He used to have a bowl hairdo in the web novels. When he first appeared in the light novels, he's a certified Bishōnen and even more so in the games.
  • Adaptational Badass: Introduction-wise, Eugeo started out as a villager in the light novels who would later work his way to become a swordsman. The video game continuity version of Eugeo? He's already a swordsman, especially in Hollow Realization, where he becomes an Integrity Knight before the aformentioned game began.
  • Adaptational Wimp: While Eugeo is no pushover in the anime, he's overall a lot less impressive than he was in the lightnovels where he was a sword prodigy who would quickly learn and master the skills and techniques Kirito taught him as well as improving upon them, whereby it was only Kirito's extensive experience that allowed him to stay ahead. In short, Eugeo really was comparable to a male Yuuki. In the anime, while Eugeo does keep up with Kirito, there is no emphasis on his exceptional talent and often times there's the impression that Eugeo still has a long way to go to bridge the gap, with only after him becoming an Integrity Knight does he surpass Kirito.
  • Adventure Duo: Eugeo is the more cautious and calmer The Lancer to Kirito’s braver and more rash The Hero. Typically it’s Kirito who decides their next move, while Eugeo either follows or adds his two cents on if this was the best decision.
  • Alternate Timeline: In Accel World vs Sword Art Online: Millenium Twilight, the Eugeo who appears there is all but stated to be from the canonical timeline and was brought into the video game continuity through the timeline shenanigans going on throughout the game, as he calls out to Kirito and remembers how they grew up together, and is saddened to realize this Kirito doesn't have those memories. He gets over it pretty quickly though as they fight, reminiscing happily that memories or no, it still is Kirito.
    Eugeo: Fairy or not, you are still Kirito, the strongest knight I know.
  • Adaptational Early Appearance:
    • In the video game continuity he's had DLC appearances in every game starting from Hollow Realization, which is long before Alicization got adapted. The explanation is always that he gets pulled into whatever game Kirito is in from the Underworld. He and Alice return in Fatal Bullet and it appears they never managed to get back to the Underworld and were drawn into Gun Gale Online instead.
    • In Memory Defrag there is an ongoing story line of Alice and Eugeo being pulled into ALO and partaking in the quest for the Divine Objects, with Alicization yet to have occur.
    • Integral Factor takes it furthest of all, with him and Alice being introduced in SAO which is adapted from the Aincrad arc, which should be years before they even existed. This one is also a case of Real Life Writes the Plot as this special was done to commemorate the airing of the Alicization anime. Even more baffling is Eugeo knows Kirito in his world and mentions having grown up with him, implying this may be the canon Eugeo just like in Accel World vs Sword Art Online. He and Alice end up staying in Aincrad to help clear SAO too.
  • All of the Other Reindeer: It's mentioned that he had no friends since Alice's arrest, partly because he isolated himself by choice, and party because people shunned him for having been close to Alice.
  • Always with You: During Kirito's Heroic BSoD, it is Eugeo's spirit returning that finally snaps him back to his senses. The implication is that traces of Eugeo's fluctlight remain attached to Kirito's.
  • The Apprentice: Kirito teaches him the Aincrad style of Swordsmanship and he often relies on Kirito for advice in other areas.
  • Arch-Enemy: To Quinella. Eugeo's most personal enemy, perhaps even more than she is to Kirito. Eugeo originally despised the Integrity Knights for capturing Alice and making her forget her memories, particularly Deusolbert, though eventually he comes to realize they are not evil and victims just like Alice and that it was Quinella who was truly responsible. Then he ends up being subjected to Mind Rape by Quinella herself, who twists his memories to make him feel like he was never loved and breaks his psyche to the point where he submits to Quinella. He gets Synthesised into an Integrity Knight where he is made to believe he only serves Quinella and yearns only for her love before being made to fight his friends Kirito and Alice. Though eventually, with the help of Kirito he finally breaks free of control and returns to Quinella where he tricks her into thinking he's still under her power, before taking an opportunity where she tried to redo his Synthesis to incapacitate her with a special dagger made by Cardinal. However due to Quinella making her skin immune to metal he fails and Quinella reveals she put Alice through forced synthesis, the equivalent of Cold-Blooded Torture, giving Eugeo into a burning hatred of Quinella. Eugeo eventually performs a Heroic Sacrifice to weaken Quinella, having Quinella fuse him with his sword and destroying one of Quinella's arms, at the cost of his own life.
  • Arc Hero: Of the first half of the Alicization arc.
  • Bash Brothers: Gains this dynamic with Kirito, with the two of them fighting alongside each other since they first met in the Underworld.
  • Beware the Nice Ones: Eugeo generally comes off as a nice and reasonable person who, like his Best Friend, is willing to help those in need. However, he has some latent anger issues stemming from his childhood and witnessing the injustices of the Axiom Church first-hand. This is shown during his encounters with Raios and Humbert's Attempted Rape of Ronye and Tiese, in which he cuts Humbert's arm off, and when he and Kirito fight the Integrity Knights, during which he's heavily Implied to be fighting with the intention to kill and actually beats Bercouli, and would have ended up killing him if not for Chudelkin's intervention.
  • Bishōnen: Drawn with very attractive and effeminate features, just like Kirito.
  • Blow You Away: Alongside ice, Eugeo seems to find himself associated with the wind element, namely when as an Integrity Knight, he uses one to propel Kirito backwards after he's disarmed by him.
  • Blue Means Cold: He has various blue outfits and wields the Blue Rose Sword, which gives him ice powers.
  • Brainwashed and Crazy: Eugeo ends up being synthesised into an Integrity Knight by Quinella, where he loses all traces of his former self and is only loyal to carrying out Quinella's will. When Quinella decides to finish the process his memories of Kirito help him regain control.
  • Break the Badass: Quinella preys on his vulnerable heart and thoroughly corrupts him until he's completely submissive to her will.
  • Breakout Character: Eugeo and Alice are insanely popular characters among the fandom, with Eugeo scoring the highest in polls among the Alicization characters. Starting from Hollow Realization, he and Alice have been featured in every SAO game as DLC content, even before their anime counterparts debuted. Kawahara even considered sparring Eugeo's death in the anime adaptation but didn't go through with it.
  • Broken Ace: He’s good looking, kind, intelligent, and Kirito notes that he has more innate skill in swordsmanship than him and could very well surpass him one day. However, he suffered an borderline abusive childhood that gave him a skewed view of love that led to him being subject to Face Heel Brainwashing courtesy of Quinella.
  • Broken Pedestal: One could argue that he has this for the Axiom Church, seeing as he goes from something of a Rules Lawyer to an outright rebel after witnessing many examples of the Taboo Indexes blatant unfairness.
  • Bromantic Foil: With Kirito, since the two of them are best friends. Kirito is the more rebellious and courageous of the two, while Eugeo is calmer, more sensible, and reserved.
  • By-the-Book Cop: His dynamic with Kirito is very much that of the straight-laced rule abider and the Cowboy Cop who doesn't care for rules. He is often complaining or worrying about breaking the rules, and relies on Kirito for guidance in areas where the rules fail him. This changes when Raios and Humbert were abusing their authority to sexually harass Ronye and Tiese. He immediately stops caring about the Taboo Index which is graphically represented by his Seal of the Left Eye shattering.
  • Call-Forward: In Accel World vs Sword Art Online: Millennium Twilight the Alternate Timeline Eugeo that Kirito meets drops a lot of reveals for the then unaired Alicization arc including the fact they grew up together as Childhood Friends and trained to be Integrity Knights.
  • Calling Your Attacks: "Enhance Arnament!" "Bloom! Blue Roses!"
  • Catchphrase: "Stay cool", which he learnt from Kirito.
  • Character Development: He starts developing the "Screw the Rules, I'm Doing What's Right!" mindset when Ronye and Tiese are about to be raped by Raios and Humbert. He also gains the resolve to save Alice and oppose the Axiom Church as a result.
  • Childhood Friends: To Alice and maybe Kirito.
  • Chronic Hero Syndrome: Eugeo has a penchant for helping others, such as when he shared his food to Kirito and offering assistance to Tiese to lessen her Valet job. Unlike most examples, however, he's also conscious of his well-being at the same time.
  • Conflicting Loyalty: While he's determined to save Alice, he also feels responsible for providing for his family, which is why he feels guilty about going off to the Academy (which results in them sending him money, rather than the other way around) and ending up as a fugitive.
  • Contrasting Sequel Protagonist: Unlike the previous Arc Heroes, Eugeo is a boy and takes up the role of Kirito's best friend. He's not a fellow gamer to Kirito, given he's an AI who resides in a fantasy themed virtual world.
  • Crucified Hero Shot: The anime has him doing this when Cardinal fuses him with his sword so he can defeat the a Sword Golem, shortly before he performs a Heroic Sacrifice by launching a suicidal attack at Quinella resulting in him getting bisected.
  • Dark and Troubled Past: Eugeo was born to a family of farmers who, save for his older sister, didn’t seem to actually care much for him and at best seemed to view him as a potential farmhand, with his father showing favoritism towards his eldest sons, which only got worse he got the prestigious calling of cutting down the Gigas Cedar, which by law prevented him from helping on the farm and prompted his father to take all the money Eugeo earned from it despite the whole thing being out of his control. He only had two friends growing up, Alice and Kirito, and one day when going on an adventure, he witnessed a Dark Knight get murdered and Alice accidentally place a few fingers in the Dark Territory, which got her arrested the next day and he was Forced to Watch due to the Seal of the Right Eye preventing him from stopping it. And, as if to add insult to injury, Kirito was logged out soon after and his memories of him were blocked, meaning he remembers Alice being his Only Friend and thus to him, all the blame fell on him. Shortly after Alice’s arrest, the majority of the village, save for his sister, Alice’s little sister Selka and the previous Gigas Cedar cutter Garritta, began to shun and ignore him due to how close he was to Alice, and he regulated himself to cutting the Gigas Cedar for the rest of his life as a distraction.
  • Deadpan Snarker: Being around Kirito has turned him into one.
  • Determinator: Once Kirito stirred him from his funk there is little that can sway him. He manages to outrigtht power through the Seal of the Right Eye to the point his eye exploded and cut off Humbert's arm immediately after, which is especially notable when Alice, an Integrity Knight, did the same later but passed out immediately after.. Even when cut in half, he managed the will to give Kirito an assist in the final battle with Quinella.
  • Deuteragonist: The Arc Hero for the first half of Alicization. His story arc is about working with Kirito to become an Integrity Knight in their quest to find Alice. He receives a considerable amount of focus and at times even takes the spotlight away from Kirito.
  • Face Death with Dignity: He accepts his death with peace, even dissuading Kirito from healing him.
  • Fish out of Temporal Water: In Accel World VS Sword Art Online, due to the time travel shenanigans of the game and the fact the game continuity is an Alternate Timeline to the canon continuity, Kirito ends up meeting a version of Eugeo from another timeline (who is implied to be the canon version). Upon seeing Kirito, Eugeo mistakes him for his Kirito and tries to get him to remember, only to be disappointed that this Kirito has no memories of their time togethernote . However after having a friendly duel with Kirito to test him, Eugeo realizes that while this is a different Kirito, it is still Kirito who fights the exact same way. He then takes up on Kirito's offer to hang out and party with him until he's able to return to his own timeline.
  • Early-Bird Cameo:
    • Eugeo makes his first voiced appearance in Hollow Realization, Accel World VS Sword Art Online, and Fatal Bullet as part of DLC, well before he appeared in the anime.
    • He's also featured as a playable character in Memory Defrag before his anime debut.
  • Expy: Of Takumu Mayuzumi/Cyan Pile being the childhood best friend of The Hero with a blue Color Motif.
  • Eye Scream: His eye bursts after breaking the Taboo Index by slicing off Humbert's arm, but Azurica heals the damage the next morning.
  • Fake Defector: Used his status as an Integrity Knight so he could get close to Quinella and assassinate her.
  • Fatal Flaw: Aside from his Chronic Hero Syndrome, his recklessness can get him into trouble at times.
  • Fighting Your Friend: Due to Quinella's forced synthesis, he ends up fighting Kirito.
  • Grew a Spine: Becomes more daring as the story goes on.
  • Go Out with a Smile: He smiles in his final moments with Kirito by his side.
  • Guardian Entity: His "spirit" shows up during Kirito's fight against Gabriel, and later in the epilogue.
  • Guile Hero: Likely something he got from Kirito’s teachings. He even managed to beat Bercouli, who is pretty much the Underworld’s Best Warrior, through this. He used his Blue Rose Sword’s special ability and stabbed it into the ceiling, charging Bercouli with a long icicle for Bercouli to break and catch him off guard. He then grabbed his sword once it fell from the ceiling and used it’s Memory Release Technique while Bercouli was still slack-jawed, trapping them both and draining Bernoulli's life, anticipating that he has less due to his older age and will die before him.
  • Half the Man He Used to Be: After Quinella slices the Sword of Blue Rose in half when Eugeo was merged, he was un-merged with the middle of his torso as blood red crystal.
  • Have We Met?: Upon Kirito's return to the Underworld, the two boys have several of these moments due to both of their memories of each other from their childhood being erased. However there are instances where memories keep seeping through and both seem familiar. When Eugeo takes a serious wound and having Alice Zuberg's memories, he finally remembers that he, Alice, and Kirito grew up together in the village.
  • Heroic BSoD: He's visibly stunned after finding out that Bercouli killed the dragon who guarded the Sword of Blue Rose.
  • Heroic Resolve: He'll save Alice no matter what it takes, even if it means breaking the rules to do it.
  • Heterosexual Life-Partners: Nakama and general best friend to Kirito, as well as one of the few close male friends Kirito's had, which makes him a Living Emotional Crutch on the same level as Asuna.
  • Hurting Hero: At the start of the arc, Eugeo is traumatized by Alice’s arrest and is guilt-ridden by his inability to stop it, but he still resolves to become an Integrity Knight himself and save her after Kirito comes back.
  • An Ice Person: His Sword of Blue Rose creates thorny vines of ice out of the ground. In terms of appearance, Eugeo consistently wears blue and white clothing and armor.
  • Identical Stranger: He almost looks like a Caucasian Kirito, with many of their facial designs including their hair styles, height, and even their clothing being the same.
  • I Just Want to Be Loved: Eugeo hasn’t had the most loving childhood, with his family being openly disappointed with his Calling of cutting down the Cigas Cedar since it costs them an extra farmhand and most of the money he earned was taken by his father, only leaving him enough to buy a subpar loaf of bread and water for lunch. The only true love he had growing up was with Kirito and Alice, with the latter being arrested and at risk of execution due to accidentally placing her hand in the Dark Territory and the former being forced to log out of the Underworld, leaving Eugeo alone with his memories of Kirito gone. This makes him understandably attached to Kirito when he comes back, albeit with neither of them remembering the other, and convinces him to go after Alice, while also being very afraid that he’ll leave him at some point. Quinella, albeit in order to manipulate him, convinces him that he's taking this to it's logical extreme by claiming that it motivates most of his actions, such as wanting to use the position of Integrity Knight to send money to his family to earn their love, and even going as far as to say that his rescue of Tiese, who had an obvious crush on him, was less motivated by her Attempted Rape by Raios being morally wrong in his eyes, but by him being angered that Raios was “taking what was his”. This culminates in Quinella Mind Raping and seducing him into lowering his core protection so she can turn him into an Integrity Knight, just by promising to love him like no one else has and to never stop loving him.
  • "I Know You're in There Somewhere" Fight: Kirito attempts this after Eugeo gets newly synthesised into an Integrity Knight. But it doesn't really work and he's forced to battle his friend.
  • Instant Expert: Lampshaded by Alice. When Eugeo is synthesised into an Integrity Knight, he is unusually proficient for a novice with a mastery of the Sacred Arts. This is because Quinella synthesised him with an improved Synthesis Module that allowed him to use the power of "Meaning" immediately.
  • Irony: It is Eugeo, not Alice, who ends up becoming the AI created for war that Kikuoka sought when he breaks free of the Seal of the Right Eye and by extension the Taboo Index on his own free will, whereas Alice broke the Taboo Index by accident and only overcame the Seal of the Right eye much later with prompting from Kirito.
  • Killed Off for Real: Ends up being cut in half during his attack that injured Quinella.
  • Last Breath Bullet: He manages to cut off Quinella's arm with his suicide attack, leaving her in a weakened position that made it possible for Kirito to defeat her.
  • Leitmotif: "The Blue Rose Battle" serves as his main theme.
  • Living Emotional Crutch: His childhood friends, Alice and Kirito were this to him. When both of them were gone, Eugeo lost the will to live and would idle his life away by spending his days trying to cut down the Gigas Cedar that was his sole life purpose. Kirito's return brings him back on his feet and he starts living again.
  • Masculine Girl, Feminine Boy: He's the gentle, caring boy to Alice's fierce Lady of War.
  • Master Swordsman: While he was still a trainee at the time, Kirito noted that Eugeo had more potential as a Swordsman than even him.
  • Messianic Archetype: The anime goes out of the way to depict him as one, with him performing a Heroic Sacrifice to take down Quinella and save humanity. He even has a Crucified Hero Shot as if he were Jesus on the cross, when he fuses with his sword.
  • Moment of Weakness: Allowing himself to be manipulated by Quinella and turned into an Integrity Knight. Quinella managed to interfere with him mentally to make him submit willingly.
  • My God, What Have I Done?:
  • My Greatest Failure: As a child, his cowardice resulted with Alice being taken to the Central Cathedral and turned into an Integrity Knight. He spent six years trying to cut down the Gigas Cedar as an excuse to forget about leaving his village... until Kirito is dumped back into UW by Rath.
  • Named Weapon: Sword of the Blue Rose.
  • Not Quite Dead: Implied. While Kirito is brain-dead, it is Eugeo's spirit who returns to will Kirito awake so he can save his friends. Kirito suspects that a part of Eugeo is imprinted on Kirito's Fluctlight and tried to find a trace of him.
  • Odd Name Out: He's the only member of the main cast whose name doesn't begin with the same letter as anyone else.
  • The Power of Hate: He despises the Integrity Knights for what they did to Alice, and gets rather upset whenever they claim to have any honor. Kirito, concerned for Eugeo, tells him that he should fight out of a desire to save Alice, rather than out of hatred.
  • Power Trio: Formed one with Alice and Kirito during the Underworld.
  • Rage Breaking Point: He explodes when he finds out that Deusolbert was responsible for arresting Alice eight years ago, and out of sheer resentment attempts to finish off a downed Deusolbert. Eugeo hesitates, however, after Deusolbert lowers his head, and is consoled by Kirito, who informs him that Deusolbert has no recollection of his past actions since his memories were erased at some point afterwards.
  • "The Reason You Suck" Speech: Gives these twice to two different Integrity Knights.
    • When he learns that Deusolbert was the Integrity Knight who arrested Alice when she was 12, he calls him out on claiming to have honor when he’s willing to arrest and execute a little girl over an accident as he prepares to kill him.
    • Gives a more subdued one to Bercouli, stating that he hates the Integrity Knights for forgetting who they how they forgot who they truly are and their Blind Obedience the Axiom Church despite multiple hints that they’re not as good as they make themselves out to be, all while claiming to be protectors of peace, justice and order despite the blatant unfairness in the Taboo Index.
  • Screw the Rules, I'm Doing What's Right!: If the rules are immoral by his standards, he would rather break them.
  • Sempai/Kohai: In the academy, he is formally Golgorosso's kohai and Teise's sempai specifically. It's a system to assist in teaching the underclassman in both situations.
  • Significant Birth Date: Eugeo's birthday is revealed to be April 10th, meaning birthday is 4/10. This alludes to Error 410 which means, "gone", alluding to his eventual fate.
  • Spared by the Adaptation: Word of God has stated that Alicization Lycoris will feature an alternate route that will allow you to save Eugeo from his unpleasant fate.
  • Start X to Stop X: He brought up the idea of fusing himself with the Blue Rose Sword to fight Quinella's sword golem despite Kirito's pleas, becoming the same as it conceptually but stronger due to his bond with Alice, injuring Quinella and finishing the golem.
  • The Stoic: As an Integrity Knight, Eugeo Synthesis Thirty-Two shows even less emotion than Alice did.
  • Stuffed into the Fridge: His brutal death at the hands of Quinella causes Kirito's Heroic BSoD and subsequent Break the Cutie moment.
  • Summon to Hand: As an Integrity Knight, Eugeo mastered a high level Sacred Art to call his sword to his hand.
  • Talking Through Technique: In Accel World vs Sword Art Online: Millenium Twilight, a version of Eugeo is pulled into the game through all the time travel mishaps going on and appears to be the Eugeo of the canon continuity. When he sees Kirito he is saddened to discover this Kirito doesn't have the memories of the one he knows, so he resorts to having a duel with Kirito to see if he truly is the one. Eugeo is delighted to discover that Kirito fights the same way, and even though this isn't his Kirito it's still Kirito.
  • Together in Death: With the young Alice Zuberg, who dies along with Eugeo, leaving only Alice Synthesis Thirty behind.
  • Took a Level in Badass: Went from a woodcutting villager, to a elite swordsman, and finally to an Integrity Knight.
  • The Tragic Rose: A big part of Eugeo's motif, shows up literally in Cardinal's story of how the Blue Rose Sword was created.
  • Unskilled, but Strong: Eugeo is noted by Kirito to be a sword prodigy, who masters skills at a staggering speed. However Kirito is still able to keep ahead of him due to years more experience and trained Eugeo himself. Nonetheless, Eugeo does eventually surpass Kirito, placing him as Strong and Skilled.
  • Vitriolic Best Buds: He and Kirito enjoy sniping at each other, but nevertheless are the best of friends.
  • What Is This Thing You Call "Love"?: Due to his poor family life, Eugeo has a skewed definition on what “love” actually means. However, as his page quote shows, he manages to find a more solid definition.
  • You Are Not Alone: His "spirit" gives one to snap Kirito out of his Despair Event Horizon.

"...However, I do not wish for this pain... this emotion I am feeling for the first time to be erased. After all, this pain is what truly taught me that I am not a knight doll, but a single human. — Esteemed Highest Minister, I do not wish for your love. I have no need for your ministrations."

One of the deuteragonists of the first half of Alicization alongside Eugeo, and later The Protagonist of the second half. A girl from Rulid Village who was friends with Kirito and Eugeo until she was taken away by an Integrity Knight for touching the gravel from the Land of Darkness. As Kirito and Eugeo later find out, she was synthesized into an Integrity Knight herself.


  • Action Girl: She’s a powerful swordswoman and is one of the strongest Integrity Knights.
  • Actor Allusion: A subtle one in Hollow Realization. While doing a co-op quest with Alice, Kirito finds a baby dragon that he must care for. He wants to name the dragon Shiro which means white, however Alice angrily rejects it due to the name not being special enough. Alice's voice actress played two characters with the word "Shiro" in their name, Mashiro Shiina from The Pet Girl of Sakurasou and Shiro from No Game No Life, with both girls being closely affiliated with a character voiced by Kirito's voice actor.
  • Adaptational Early Appearance:
    • In the video game continuity she's had DLC appearances in every game starting from Hollow Realization, which is long before Alicization got adapted. The explanation is always that she gets pulled into whatever game Kirito is in from the Underworld. She and Eugeo return in Fatal Bullet and it appears they never managed to get back to the Underworld and were drawn into Gun Gale Online instead.
    • In Memory Defrag there is an ongoing story line of Alice and Eugeo being pulled into ALO and partaking in the quest for the Divine Objects, with Alicization yet to have occur.
    • Integral Factor takes it furtherest of all, with her and Eugeo being introduced in SAO which is adapted from the Aincrad arc, which should be years before they even existed. This one is also a case of Real Life Writes the Plot as this special was done to commemorate the airing of the Alicization anime. To complicate matters more, this Alice is already an Integrity Knight as opposed to a child. And then, after Alice departs the world it turns out she's returned to her own world, where it was like her memories of her time in another world had faded and she lived out the same life as she did in canon until she gets returned back to Aincrad again when War of the Underworld began airing.
  • Adorkable: She's an Integrity Knight and a Robot Girl with No Social Skills. Do the math.
  • Alice Allusion: She's a literal Alice archetype, especially as a child.
  • All-Loving Heroine: Young Alice Zuberg was said to love everyone and everything and her feelings of love was so strong that the memory crystal removed from her was unable to be used for the Sword Golem.
  • Always Someone Better: As the Third Ranked Integrity Knight (and later possibly first), she is on the giving end to Kirito. When the two of them duel, Kirito finds himself completely overpowered. In fact Kirito, not being vanquished in one hit by her is already considered impressive by her standards.
  • Arc Hero: She's a tritagonist in the first half of Alicization and later the sole The Protagonist of the War of the Underworld half given Kirito takes a back seat.
  • Arch-Enemy:
    • To Quinella, though not as strongly as the boys. Given the Pontifex had a hand in ruining everything about her peaceful life, including a painful Forced Synthesis and then stripping her of all her memories (or rather Alice Synthesis Thirty taking over the body of Alice Zuberg who became separated from her body). As Alice gets her eyes opened up to the truth by Kirito, she eventually has a Heel Realization and makes it her new mission to joins Kirito and Eugeo in rebelling against the Church and bring Quinella down.
    • To Vector/Gabriel Miller. The man dedicates himself to capturing Alice's soul and having it for himself while being at the forefront of the Dark Territory's attack on the Human Empire, which Alice fought so hard to protect.
  • Audience Surrogate: When Alice takes over as The Protagonist in War of the Underworld, she starts playing this role from time to time due to being Locked Out of the Loop and asks questions in place of the audience.
  • Badass Cape: Dons a bright blue one as part of her Integrity Knight outfit.
  • Bag of Spilling: The sudden merging of the Seed-built VRMMOs in Unital Ring resulted with Alice's stats being reset.
  • Because You Were Nice to Me: In Accel World vs Sword Art Online: Millennium Twilight, Alice accidentally gets transported to ALO and believes all the players to be enemies from the Dark Territory and attacks on sight, including Kirito. With no choice Kirito is forced to fight her and narrowly wins. However Alice is shocked that Kirito doesn't kill her when she's down and realizes she had wrongly identified them as enemies. After hearing out her story, Kirito offers to let Alice hang out with them until she finds a way home, to which she accepts.
  • BFS: Downplayed. Her Osmanthus Blades's not as big as other examples in the series, but it has a noticeably longer blade than say, Kirito and Eugeo's swords. She also specializes in Bastard Swords in Unital Ring.
  • Big Eater: Hollow Realization shows Alice ordering over eight scoops of ice cream, with each having a different flavor, in a single cone.
    • Some narration in the Light Novel has her remember Bercouli mentioning that her cheeks looked a bit fuller after she arrived to the Human Army Camp, to which she sheepishly admits to herself that she was a big fan of Selka's cooking.
  • The Big Gal: Once she joins Kirito's party, there is no one who can top Alice in terms of raw power, with her being hands down the strongest.
  • Breakout Character: Alice and Eugeo are insanely popular characters among the fandom. Starting from Hollow Realization, she and Eugeo have been featured in every SAO game as DLC content, even before their anime counterparts debuted.
  • Casting Gag:
  • Cat Girl: After making an account in ALO, Alice took the form of a Cait Sith as her avatar in Material Edition 22.
  • Celibate Hero: Shows shades of this at first during her days serving as an Integrity Knight, feeling her duties in protecting her people mean she does not have the time to engage in the pleasantries of falling in love. Though she does eventually grow out of it and gets in a potential Love Triangle with Kirito, Asuna, and herself.
  • Childhood Friends: To Eugeo and Kirito.
  • Child Prodigy: Revealed to have mastered many spells of the Sacred Arts at the age of ten.
  • Clingy Jealous Girl:
    • She and Asuna get into a fight when Asuna logs into Underworld to meet Kirito.
    • At the end of Alicization, she and Asuna are exchanging Death Glares at each other after the latter saw her seating behind Kirito's motorcycle and tightly hugging him.
  • Cloning Blues: When first told of the Synthesis Ritual, she derides herself as a thief who stole the original Alice’s body.
  • Color Motif: Gold. She's blonde and wears gold-plated armor. Blue also tends to be her secondary color, as she possesses piercing blue eyes, along with both her childhood and Integrity Knight outfits heavily featuring blue.
  • The Comically Serious: Even more so than Sinon. She's almost never casual when she speaks and when she sets her mind on a task nothing can sway her.
  • Contralto of Danger: As a grown up, she has quite a deep voice for a girl, which is unusual for Ai Kayano. It's a far cry from how she sounded like when she was young.
  • Cool Big Sis:
    • To Selka. Despite Alice having no memory of her Selka, she still showers her with sisterly affection with the latter always overjoyed by her presence.
    • To Silica, whom she helped in fending off some Player Killers during their recent adventures in ALO. Alice's younger sister Selka also looked up to her.
  • The Cutie: Young Alice Zuberg was a sweet innocent child who lived life to the fullest with her two best friends, before one day it was all snatched away from her.
  • Dark and Troubled Past: She was originally just an ordinary girl with a skill for Sacred Arts who lived a fairly normal life, with her two her Best Friends and a family consisting of her father, mother and younger sister. That all changed when she accidentally placed her hand in the Dark Territory where every Underworld citizen is forbidden from going, getting arrested with the threatened fate of execution looming over as she’s flown to the church hanging off a dragon. While she’s spared from being executed and is told that she can go home if she studies hard enough, it turns out this was a lie to motivate her to polish her skills so she can be turned into an Integrity Knight. When she refuses to become one out of fear of forgetting those she loves, she’s forced through the more painful Forced Synthesis Ritual and forgets everything anyway, with this new personality being forced to become a Child Soldier for the Axiom Church.
  • Death of Personality: Alice Zuberg and Alice Synthesis Thirty are considered two different people, and Kirito realizes that restoring the former's memories will 'kill' the latter. Eugeo even makes note of this as he's dying, deciding to pass on with Alice than fight his best friend to return Alice back to her body.
  • Defrosting the Ice Queen: She came the furtherest out of all the female leads, going from trying to kill Kirito, to reluctantly allying with him, and finally opening up and accepting him as a friend. The Alice after her Character Development is an almost completely different person, being kind and polite as well as constantly smiling.
  • Deuteragonist: While she went Out of Focus at first, she later works her way into being the third main character after Kirito and Eugeo, and later takes over as the main lead during the second half of Alicization. She could also be considered the overall lead character of Alicization given her importance to the story and Kirito going Out of Focus.
  • Dishing Out Dirt: Her attacks are usually associated with the Earth element. Namely, her Osmanthus Blade in the Underworld was forged from the world’s first Osmanthus tree, allowing it to take the form of one to regain durability and turn it’s blade into a storm of flower petals to slash enemies.
  • Don't Call Me "Sir": Despite being an Integrity Knight, she insists that Ronye and Teise don't have to be formal with her when she meets them again in Volume 15.
  • Dragon Rider: Her personal dragon is a large, silver female one named Amayori, who she's rather affectionate towards. Amayori's brother, Takiguri, starts following Alice after the death of his master Eldrie. This is mainly her reason of becoming a Cait Sith.
  • Dude, She's Like, in a Coma!: At one point, it looks like she was about to kiss Kirito while he was in the middle of his Angst Coma, if not for Ronye and Tiese interrupting.
  • Early-Bird Cameo:
    • Alice makes her first voiced appearance in Hollow Realization, Accel World VS Sword Art Online, and Fatal Bullet as part of DLC, long before she appeared in the anime.
    • She also appears as a playable character in Memory Defrag before her anime debut.
  • Expy:
    • One to Alice in Wonderland, given she's an Alice Allusion, with the theme of a person from the real world falling into a fantasy one. Her outfit as a child has the exact color scheme as Disney's Alice with the blue and white dress. There have also been quite a few references to the story when discussing Alice, with Asuna namedropping Alice in Wonderland a few times when talking about Rath and the Underworld. In Fatal Bullet, Subtilizer directly references this by mentioning a "rabbit" heading to Wonderland before adding he'll see Alice again soon.
    • She could also be one to Saber. Both are stoic knights who were introduced as being completely cold and aloof to the main character before defrosting thanks to them, were honor-driven to the extent that it served as their detriment, and have artificial originsnote .
  • Everyone Has Standards: While she was once a loyal servant of Quinella and the Axiom Church, having little issue with enforcing the Taboo Index and displaying a willingness to kill those who defy it, she’s shown to have a great disdain for most of the Underworld’s nobility and has clear reservations about the privileges they have and their general arrogance due to the laws.
  • Eye Scream: Her right eye literally bursts when thinks of she defying the Axion Church, due to the Seal of the Right Eye taking effect.
  • Eyepatch of Power: After the above incident, Alice is forced to wear an eyepatch like this, since it isn't possible to heal her eye right away.
  • Famed in Story: The prologue of Unital Ring had an incident involving Alice angrily calling out a group of Salamander Player Killers, forcing them to whine like Dirty Cowards and apologize to Silica for hurting her before running away. The aforementioned incident is later called “The Legend of Lady Alice scolding PKers until they cried”.
  • Fire-Forged Friendship: With Kirito, more so than any other character. Their first reunion has them as enemies, in which she is tasked with capturing them and executing them. When he and Eugeo meet Alice again in the tower, she fights them with killing intent. It takes them both being thrown out the tower and forming a truce to survive the climb (during which Kirito saves Alice's life multiple times) where Alice is gradually swayed over to Kirito's side and places her trust in him.
  • Fish out of Temporal Water: In Hollow Realization she accidentally ends up in Sword Art: Origins. She has immense difficulty adapting, as she lacks even the most fundamental knowledge about VR games and even the modern real world. In fact she doesn't even understand what "Virtual Reality" is or the fact she's in a game, believing she's in some sort of foreign land. Kirito has to explain everything to her and even then she still has trouble, thinking that Kirito's fancy modern words are riddles.
  • Florence Nightingale Effect: Implied. Having started off trying to kill him, reluctantly working with him when both their lives are at risk and only recently becoming allies after she sides with his and Eugeo’s rebellion, there are very little hints that she regards Kirito in a romantic light in the first half of the Alicization Arc, likely viewing him as a Fire-Forged Friend at best. After the battle with Quinella however, where he loses an arm and enters an Angst Coma, she becomes his caretaker and nurses him to the best of her ability, even fleeing the Human Capital in fear of him being executed or murdered. Six months after taking up the task, she finds herself acting more affectionate and is heavily implied to have fallen in love with him.
  • Go Out with a Smile:
    • A non-lethal example. When young Alice gets taken away as a child by an Integrity Knight, it was believed that she would be executed. As she is chained up and flown away she smiles to Kirito and Eugeo.
    • Later when Eugeo dies along with the young Alice, their spirits are seen walking off together and smiling as they look back.
  • Helmets Are Hardly Heroic: Despite being an Integrity Knight, she is never shown wearing a helmet while on duty, unlike Deusolbert and Fanatio.
  • Heroic BSoD: She had a minor breakdown after Kirito told her about the Integrity Knights and mentioned her sister's name.
  • Heroic Willpower: Like Eugeo, Alice is one of the only residents of the Underworld who had a strong enough willpower that allowed her to defy the Taboo Index of her own volition. After being shown the truth by Kirito, Alice decided to turn on her old allegiance, which results in the "Seal of the Right Eye" bursting her eyeball.
  • Honor Before Reason: She initially wanted to choose death than the dishonor of being saved by a criminal. However Kirito's argument over what an Integrity Knight stood for and what was really important does sway her from this.
  • Hope Bringer: Kirito sees her as "the hope that connects everyone's will to the future".
  • Humble Hero: When Kirito and Asuna asked her and Eugeo to stay at their place in Memory Defrag, she said that "hospitality isn't necessary" and she can "handle herself", only for Kirito to point out that she's not familiar with ALO culture.
  • Identity Amnesia: Through her synthesis. Her original self as Alice Zuberg dies with Eugeo.
  • Incorruptible Pure Pureness: The young Alice Zuberg resisted her Synthesis to the very end and refused to allow her memories to be taken away. This led Chudelkin to resort to Forced Synthesis which ended up separating the young Alice Zuberg with the Integrity Knight who would come to be known as Alice Synthesis Thirty.
  • In the Hood: After leaving the Central Cathedral with a crippled Kirito, she took to wearing a cloak to keep her identity obscured.
  • I Owe You My Life: One of the reasons she gains Undying Loyalty to Kirito and develops feelings for him. Kirito freed her from the lies that bound her and saved her from being killed by Quinella when she tried to perform a Taking the Bullet moment.
  • I Regret Nothing: She never had any regrets in the path she took. Her father understood why.
  • Irrational Hatred: Played With. Alice herself doesn’t completely understand where her initial dislike of Asuna comes from. When her original reason, believing she was a spy trying to hurt the defenseless Kirito after she entered his carriage unannounced, quickly subsides thanks to Bercouli’s intervention and explaining that they’re on the same side, she still finds herself acting hostile towards her. She chalks it up to some form of envy, but doesn’t know whether it’s due to how close she seems to be to Kirito, her skill and power with a sword creating a sense of rivalry, or the fact that she finds Asuna to be so beautiful that she would have easily believed her to be the Goddess Stacia like everyone initially assumed if Asuna bothered acting the part.
  • It's Personal: Towards Gabriel for killing Bercouli.
  • Knight in Shining Armor: The "shining amror" part is that Alice's standard attire has golden armor on it.
  • Lady of War: She openly admits to Kirito that as an Integrity Knight, she lives to fight and doesn't want to Stay in the Kitchen (although Kirito has legitimate reasons for not wanting to let her fight, since Gabriel is after her at that time).
  • Leitmotif: "She Was Sitting Under The Osmanthus Tree" serves as her personal action music.
  • Lethal Chef: A Running Gag is Alice does not have good cooking skills. When she became Kirito’s caretaker after Quinella’s defeat, Selka had to make and send them food and enjoyed poking fun at her sister’s inability to cook, namely the fact that she tried using Sacred Arts to do it.
  • Literal Split Personality: Due to the unorthodox "Forced Synthesis" used to convert her into an Integrity Knight, the original Alice Zuberg became a separate individual with her own FluctLight and ended up being trapped in the memory crystal. As this Alice was taken when she was just a child, she forever retains this appearance. This original Alice Zuberg ends up dying with Eugeo as they head off to the afterlife together.
  • Living MacGuffin: Becomes this in the War of the Underworld, being the "Priestess of Light" Vecta is trying to capture. In reality, it's because she's considered to be the most advanced Artificial Intelligence in the world at the time, which the U.S. hope to capture or destroy through Glowgen Defense Systems to ensure they have the edge in AI technology and their implementation into warfare.
  • Locked Out of the Loop: Kirito never told her about Asuna, so when Asuna arrives in Underworld, from Alice's perspective, some stranger is trying to put the moves on the catatonic Kirito.
  • Mage Killer: She, or at least her initial Earth-Element Unit, is this in Rising Steel, possessing an attack skill that lowers the damage dealt by magic skills and a buff skill that increase the magic defense of her and her allies.
  • Magic Knight: Skilled in both swordplay and magic.
  • Masculine Girl, Feminine Boy: She's the fierce Lady of War to Eugeo's gentle and caring boy.
  • Master Swordsman: She’s been trained in swordsmanship ever since she became an Integrity Knight and is suggested to have been fighting in Dark Territory alongside her fellow knights since she was Synthesised, meaning she has about 6 years worth of experience with a sword by the time she’s sent to arrest Kirito and Eugeo and it certainly shows from their first fight onwards, with her being able to keep even Kirito on his toes.
  • Meaningful Name: A coincidental example. She ends up being considered by Kikuoka as the true Top-Down AI that Project Alicization was started to create, and she just so happens to share her name with it’s namesake, Alice in Wonderland.
  • More Dakka: Her primary weapon in Fatal Bullet is a fully-automatic Daewoo USAS-12 shotgun.
  • Named Weapon: Fragrant Olive Sword.
  • No Social Skills:
    • In regards to outside UW culture, Alice is very blunt. She even reveals Kirito's heroism in the UW and boldly addresses his uncle/adoptive father as "father" prior. Suguha is shocked at the latter part.
    • In various game adaptations, Alice has problems whenever she gets dragged outside of the UW and had a habit of attacking players on sight.
  • Not So Above It All: When Ronye notes that Kirito, during his Angst Coma, seems to be feeling a bit better, Alice jokes that it might be because he spent the night surrounded by four beautiful woman, as she, Asuna, Ronye and Sortiliena spent the previous night in his room.
  • Not So Stoic: Although she remained serious for the a very long period of time, conversing with Kirito about her values and her old life that she had forgotten stirred up emotions that had been buried deep within her. Eventually Alice goes through some Defrosting the Ice Queen and displays emotion in tense situations, such as the fight against Quinella or caring for the paralyzed Kirito where she is shown crying.
    • Eldrie's Undying Loyalty to her stems from this. During the time when he was still new and resented her, he happened to stumble upon her weeping over the death of Amayori and Takiguri's mother, which gave his perspective of her a complete 180.
  • Odd Friendship: With Suguha, who is also an expert swordswoman like her.
  • One-Woman Army: She boasts the highest kill count out of all of the main cast of permanent human casualties. Other characters only rank higher in terms of NPC mobs or temporary in-game Death Is Cheap Player Killings.
  • Out of Focus: She disappears for a significant portion of the first half of Alicization (Volume 9 and 10, as well as the first half of 11), with the main story arc being Eugeo and Kirito trying to find her and get her back. It isn't until Kirito and Eugeo break the Taboo Index that she makes a return, as the Integrity Knight sent to apprehend them.
  • Perpetual Frowner: She smiles even less than Sinon does.
  • Pervert Revenge Mode: This one verging on Ungrateful Bitch considering the circumstances but nonetheless still Played for Laughs. After Alice breaks the Seal of the Right Eye, causing her eye to explode and passing out from the shock, she awakens to discover Kirito has carried her on his back to the top of the tower. However, she notices that her clothes are drenched in sweat, to which she becomes flustered and shoves the exhausted Kirito's head on the ground to prevent him from looking at her.
  • Petal Power: The Fragrant Olive Sword creates a cloud of golden, razor sharp petals that Alice can direct at will.
  • Pint-Sized Powerhouse: She's noticeably shorter than a great deal of her opponents, including Kirito and Eugeo, yet she's the third ranked Integrity Knight and possibly the World's Best Warrior of the Underworld excluding Physical Gods.
  • Power Trio: Forms one with Eugeo and Kirito in the Underworld. Asuna would later take over Eugeo's role in the trio as of Unital Ring.
  • Pretty Freeloaders: She sneaks into Kirito's place by simply packing herself in a box to get out from Rath. It's only for a single night though, and Rinko seems cool with it after a talk with her on the phone.
  • Primary-Color Champion: In contrast to Kirito's black getup, Alice has blonde hair and blue eyes, and wears primarily gold and blue with white.
  • The Protagonist: She takes over from Kirito in the War of the Underworld half of Alicization, as Kirito is out of commission.
  • Rapunzel Hair: Alice's ponytail extends well past her waist.
  • Rei Ayanami Expy: Even more so than Shino Asada/Sinon. While she lacks the outlandish hair coloring (at least in-game) and pale skin, she's also much more stoic than her (even after defrosting), is incredibly socially-inept outside of UW, and was an AI that got a robot body. She even gets an Asuka-esque counterpart with Asuna. Being also an expy of Saber (who herself is one) probably helped.
  • The Rival: Downplayed. Alice Sees Asuna and Sinon as these in regards to Kirito, especially with the former. Asuna and Alice can get along with each other and have little issue fighting together, but when Kirito enters the equation they can start to show signs of animosity towards the other, such as when Kazuto and Alice met Asuna at RATH and the two ended up glaring at each other over how the former was hugging Kazuto from behind since they were both riding his bike.
  • Robot Girl: After being sent to the real world by Asuna, she adopts a robot body that looks identical to her UW avatar.
  • Same Character, but Different: The original Alice Zuberg who grew up in Rulid Village ends up becoming an entirely different individual to the Integrity Knight Alice Synthesis Thirty. Unlike most examples of this trope, this is due to a Literal Split Personality where the original Alice Zuberg was forcefully extracted from her body which led to the creation of Alice Synthesis Thirty. While Eugeo wanted to bring back his Alice Zuberg, Kirito became attached to Alice Synthesis Thirty. This ends up being played very literally as once Eugeo dies, he is shown departing with the spirit of the young Alice Zuberg, while leaving Kirito with Alice Synthesis Thirty.
  • Spell My Name with an "S": Official translations give her surname as "Zuberg" but sometimes "Schuberg" will pop up due to the German origin of the name.
  • Strong and Skilled: She has trained her entire life to be an Integrity Knight and becomes a Master Swordsman. She's also an impossibly strong One-Woman Army who is a candidate for World's Best Warrior.
  • Sweet Tooth: If ordering over eight scoops of ice cream in Hollow Realization is anything to go by.
  • Sympathy for the Devil:
    • Despite her utter contempt for him even before her Heel–Face Turn and having tried to skewer just moments before, she is disgusted with Quinella’s complete disregard over Chudelkin’s death and casual flinging of his corpse in spite of his utter, albeit obsessive, loyalty to her.
    • During the War of the Underworld while charging up a Sacred Art using the life energy of those who died, she finds herself surprised that she cannot sense a difference between the souls of the humans and those of the Dark Territory’s non-humans, giving her a new perspective on the former. This change shows when, after the Ogre leader Furgr dies by her hand in a fruitless attempt to capture her, she scatters his remains into the wind with an Aerial Sacred Art as a sort of memorial.
  • Taking the Bullet: Does this when Quinella attempts to finish off Kirito while he goes through a Heroic BSoD after Eugeo is cut in half. He subverts this however after getting a sudden flashback to the time Asuna did the same thing to save him from Heathcliff, with the guilt of him letting it happen again motivating him to intercept the blow and save both of them.
  • Talking Through Technique: Like many other characters in the series, Alice believes that some messages can only be conveyed through the sword. She uses fighting Kirito to assess how he attained such power and his true intentions.
  • Tomboy and Girly Girl: With Asuna, being the tomboy to her girly girl. Alice Synthesis Thirty was created to be a soldier and has fully dedicated her life to being a Lady of War. She remains The Stoic the majority of the time and does not allow herself to partake in trivial activities as most girls her age do.
  • Took a Level in Badass: Started off as a young girl in village who should talent for the Sacred Arts, but went on to become one of the strongest Integrity Knights in the Underworld who is more than a match for Kirito. She only grows stronger yet over time, where eventually Bercouli is confident she has surpassed even him.
  • Too Good for This Sinful Earth: Young Alice Zuberg is one of the most purehearted characters in the series, being an All-Loving Heroine with Incorruptible Pure Pureness. She ends up dying with Eugeo while Alice Synthesis Thirty remains in her former body.
  • Tragic Keepsake: After his Heroic Sacrifice, Alice takes possession of Eldrie’s Frostscale Whip, but is never seen using it.
  • Tranquil Fury: After a Jerkass reporter asks her and Rinko to prove she's an AI by opening her head and showing everyone her brain, she responds by asking if he's a human and if he can prove it. After he gives a bewildered acknowledgment and questions how he can prove it, she asks him to do so by opening up his head and showing her his brain. Suguha recognizes that Alice was pissed by that comment.
  • Tsundere: The most "Tsuntsun" out of all the girls, being very cold and rarely showing any open displays of kindness. Even after her Defrosting the Ice Queen phase, she still prefers to stick to her lonesome and is prone to bouts of anger. She finally mellows out after Quinella's defeat and spending time looking after Kirito, where she begins to smile and is actively polite and kind to others.
  • Used to Be a Sweet Kid: Before she became a battle-hardened Lady of War she was quite a sweet little girl.
  • Unwitting Pawn: Turns out that Quinella manipulated Alice into doing her dirty work. The same goes for the other Integrity Knights too.
  • Weak, but Skilled: Her ALO account is out of Kirito's league, but like Sinon, she makes it up with her fighting skills. In Material Edition 22, she single-handedly fends off some Player Killers with Silica.
  • What the Hell, Hero?: Alice is not pleased at Kirito's decision to stay behind in UW for 200 years. Kirito feels guilty about it.
  • World's Best Warrior: Among the Integrity Knights of the Human Empire, she was ranked third strongest. However as of the second half of Alicization she has become even stronger since and mastered the Sacred Arts full potential, so that Fanatio puts her at the strongest Integrity Knight of all.
  • You Can't Go Home Again: After the battle in Centoria Cathedral ends, she returns to her home village, only to find that she's still being treated as a criminal, despite being unable to remember her crime of stepping into the Dark Territory, and her own father prohibits her from returning.

"They say your character is built by life’s challenges, so keep soldiering on young man."

Kirito's first friend and comrade in SAO. After Kayaba trapped them, he and Kirito parted ways to gather his real-world friends, in the process forming "Fuurinkazan", a guild famous for having all of its members survive SAO. Later in ALO, he joins Kirito's party as a Salamander-type swordsman.


  • Action Survivor: He was just an ordinary Japanese Salaryman who played video games in his free time before being trapped in SAO. Luckily, the deadly scenario he was trapped in was one that required the gamer knowledge he’s accumulated to survive.
  • All Love Is Unrequited: The poor guy never manages to score the definite girl of his life. He's desperate enough to marry an NPC at least. Not even then is he successful.
  • Anything That Moves: He will make a move on any new girl he comes across, having been described to hit on anything that has a pulse. This even holds true for NPC girls who don't have advanced AI and only capable of giving default responses.
  • Authority Equals Asskicking: As The Leader of Fuurinkazan.
  • Badass in Charge: He's the guild leader of Fuurinkazan, but no slouch himself, being an Assault Team member and one of the strongest players in SAO.
  • Badasses Wear Bandanas: Wears a red Samurai-esque bandana.
  • Beware the Silly Ones: Klein is a humorous man who is the groups bonafide Butt-Monkey no matter the situation. He's also one of the most skilled players in the series. In SAO he was comfortably among the top five best players, only being beaten by Kirito, Asuna, and Heathcliff, and in every other game, he consistently stays right around Kirito's level.
  • Beyond the Impossible: In Fatal Bullet, Klein fixates on a Type-B ArFa-Sys at the Governor's Mansion that he considers cute, and continually tries asking her out on a date. Despite everyone telling him her responses are limited because she's a Type-B, he insists there must be a hidden quest he can trigger if he just talks to her enough times. He's right, and she does eventually give him the location of a special buried treasure chest, much to everyone's surprise.
  • Big Brother Instinct: He develops a small one towards Kirito, showing it in ways such as asking Asuna to take care of him and telling him to stay alive in the game.
  • Birds of a Feather: In Accel World vs Sword Art Online, Klein immediately hits it off with Ash Roller, who is an equally flamboyant and larger than life cool-guy.
  • Boisterous Bruiser: Loves a good fight, and isn't afraid to yell his enthusiasm.
  • Bromantic Foil: Has this dynamic with Kirito. He's the closest Kirito gets to a Heterosexual Life-Partners, and his excitable, outgoing personality contrasts Kirito's stoic, introverted solo-player choice.
  • Bruiser with a Soft Center: Is one of the nicest guys in the series, with a really soft heart, and has cried the most out of all the characters. He is also a badass swordsman with balls of steel, and an excellent leader.
  • Butt-Monkey: Gets ignored by the plot and gets little respect from his friends, who constantly pick on his failed love life and attempts to get a date despite being an accomplished clearer.
  • Casanova Wannabe: Fancies himself as a charming lady's man, but in reality his behavior always drives girls away.
  • Character Exaggeration: The game adaptations crank up his hopeless romantic side and make him far more perverted, while in canon he's a lot more composed and can be badass when he chooses to.
  • Chivalrous Pervert: A very loyal friend and comrade, who also likes to ogle schoolgirls.
  • Color Motif: Always dresses in red, in both SAO and ALO.
  • Cool Big Bro: He tries to be this to his school-aged friends, but more often than not has his maturity and competence eclipsed by them. Still, he still comes in awfully handy at times, such as being able to drive his "little sisters" at night when they need to get to places safe and fast.
  • Crouching Moron, Hidden Badass: As much of a goofy hopeless romantic Butt-Monkey as he first appears, Klein is a very formidable player, being strong enough to be on the Assault Team and leading his own guild.
  • Digging Yourself Deeper: At the start of the Calibur arc, he mentions that their party could really use some more spellcasters, only to get reprimanded that he's not exactly swish-and-flicking, himself. He tries to defend himself as being a samurai, which prompts Asuna to point out that classic RPG samurai are Magic Knights. When he claims that he would rather give up his title as a samurai than use magic, Yui points out that ALO's element-enhanced Sword Skills are magic for magic-haters. Kirito has to dig him out with the counter of "You don't chant when you use a Sword Skill, so it doesn't count."
  • Dogged Nice Guy: A non-romantic example to Kirito. He keeps trying to get Kirito to join Fuurinkazan and tries to pull him out of his loner shell, but isn't as successful as Asuna. When he realizes Asuna's feelings for Kirito, he asks her to take care of him.
  • Early-Bird Cameo: Appears in the news report in the first minute of the first episode.
  • Face of a Thug: Is described as this by Kirito. The avatar he originally made for himself in Aincrad is said to be much more handesome.
  • Ephebophile: Klein (24 to 26 years old), has shown by his Hot-Blooded enthusiasm for bubbly girls like Yuna the Virtual Idol in Ordinal Scale and of course Asuna (7 years his junior), shows a tendency to fall in love at the drop of a hat for cute and cuddly girls significantly younger than he is. Were they not virtual avatars and were he not such a gentlemanly Nice Guy who does not act on his desires, this would easily get him thrown in jail in real life.
  • The Ham Squad: His guild, Fuurinkazan, are just as hammy and boisterous as he is.
  • Best Friend: Is the closest Kirito gets to one prior to Eugeo, being the first and oldest friend he has from SAO who is not a girl and not in love with him.
  • Hero of Another Story: Klein has had his own adventures in SAO, and the story of how Furinkazan went from being a noob guild to the Action Survivor guild is one worth telling one day.
  • Hidden Depths: The Sword Art Offline shorts show Klein to be surprisingly skilled at life counselling.
  • Hot-Blooded: High energy and passion goes with being a Boisterous Bruiser.
  • I Will Wait for You: A non-romantic example. He always holds a open hand to Kirito to join him and even when he is at his emotional nadir, Klein still was friendly to him and wanted to help him, even when it seemed Kirito might be willing to fight him.
  • Katanas Are Just Better: In SAO, he gained the rare ability of equipping katanas. That's why he becomes a samurai in ALO. This is justified in Hollow Fragment, where most Katana skills can inflict bleed.
  • The Lancer: Plays this role during the Calibur arc, acting as a Hot-Blooded contrast to the level-headed Kirito.
  • Let's Get Dangerous!: In times of seriousness Klein drops his goofy moron act and becomes a badass force to be reckoned with.
  • Like Brother and Sister: When he finally gets it through his thick-skull that he does not have a snowflake's chance in hell with the beautiful girls that hang around Kirito, Klein settles for regarding them as family instead, casually having conversations about dating and seeking love-advice from them (Liz in particular) like a goofy big brother would with his close little sisters.
  • Manchild: He's in his twenties, but at times can act as (if not more) immaturely as the kids he hangs out with.
  • Martial Arts Headband: His main shtick, even in real life, is wearing one of these.
  • Mistaken for Pedophile: Played for Laughs in the games. In Accel World vs Sword Art Online: Millennium Twilight Kirito noticed that at one point Klein appears to have a crush on the then twelve year old Idol Singer Seven, and was worried he would try to hit on other Token Mini Moes like Utai and Niko. Klein elaborates that his affection for Seven was only speaking from the point of view of a dedicated fan, and he had no interest in children whatsoever.
  • Morphic Resonance: Even before Kayaba reset everyone's avatars, Klein looked pretty much the same save for having longer hair than his real life appearance, and generally a little more distinguished rather than thuggish.
  • Nice Guy: Beneath his gruff, lecherous persona is a kind soul. In SAO, his first action post-entrapment was to find his friends and bring them under his wing.
  • No Poker Face: In Hollow Fragment, when the gang play Texas Holdem, Klein tries to bluff with an All-In when he only has a measly hand of a pair of 4's, which Kirito immediately picks up on and beats him to.
  • Not So Different: In Accel World vs Sword Art Online, Klein sympathizes with Taku as both of them were the respective Third Wheel guys among the large harem of girls following the Chick Magnet heroes around.
  • One of the Kids: He's in his twenties, yet he gets along well with all of the younger characters, acting just as goofy and immature.
  • Online Alias: Klein.
  • Overshadowed by Awesome: Klein is one of the top players in SAO, and his guild managed to survive SAO unscathed. Not even the Knights of Blood can boast of a zero mortality rate. Not to mention that his Katana extra skill is considered incredibly rare due to having unclear conditions to unlock. He'd be The Hero in any other setting but for the fact that among his friends are the Dual Wielding "Black Swordsman" and the "Lighting Flash" lady warrior in white. He gets a chance to shine in the Calibur arc, where he proves to have some damn big brass balls, and also in Ordinal Scale where his guild defeats several special enemies.
  • Plucky Comic Relief: Klein largely serves this role, providing some lighthearted humor during tense times.
  • Right for the Wrong Reasons: In Calibur, he insists on saving Freyja even though everyone else is sure it's Schmuck Bait. This decision saves the team's ass, but not without some Brain Bleach due to Freyja's true identity as Thor.
  • Real Name as an Alias: His real name of Tsuboi. His character name is Klein referencing a Klein Bottle. In Japanese, this would be pronounced as Kurain no Tsuboi
  • Samurai: Designs his SAO and ALO characters around this class even though SAO and ALO are classless, and attempts to roleplay as a samurai too. He has the katana, the bandana, and follows Bushido (or rather, the theme park version of it). Even when he plays GGO, he has a preference for Japanese-made weapons, specifically the Howa Type 64 battle rifle listed below.
  • Spider-Sense: Like Kirito, he possesses the hypothetical skill, Hypersense.
  • Spirited Competitor: He won't go around picking fights, but he isn't afraid to show off his enthusiasm.
  • Third Wheel: Klein often feels this way being the only guy among Kirito's Unwanted Harem, watching all the girls fawn over him while he gets no love.
  • Throw the Dog a Bone: He gets little screen time in the main series and is often the butt of jokes, but in the Ordinal Scale film he plays a major role and scores several awesome moments alongside his guild.
  • Token Adult: He's in his twenties, and after the Fairy Dance arc is almost always part of Kirito's circle of friends.
  • Took a Level in Badass: He starts off a complete and total noob who had trouble with the starter enemies, to one of the best players in SAO by the end, and he leads his own guild which had nobody die in it. Not even the Knights of the Blood Oath can boast that!
  • Vitriolic Best Buds: While he and Kirito usually get along, Klein has a tendency to get on Kirito's nerves, usually in relation to girls, which leads to Kirito hitting him. It is worth noting is Kirito is typically the one on the receiving end when he's with any other character, but with Klein it's the inverse.
  • Weapon of Choice: Katanas, unsurprising since he roleplays a samurai. In SAO, he used the "Karakurenai". In Fatal Bullet, he uses weapons that were once standard issue with the JGSDF, namely the Howa Type 64 battle rifle, and the Panzerfaust 3 rocket launcher.

Click here to see Agil in Ordinal Scale 

An ax wielding merchant who runs a shop in SAO while his real-world wife runs Dicey Café, his real life one. In ALO, he reprises his SAO job as a Gnome.


  • Adam Smith Hates Your Guts: His store's MO is to buy cheap and sell expensively. Turns out he uses his profit to support lower-level players and a local church.
  • Anime Accent Absence: He's African American, yet he speaks perfect Japanese. Though unlike the rest of the characters, he's the only one who speaks perfect English too, while the rest of the characters retain a Japanese accent when speaking English words.
  • An Ax To Grind: Carries a massive ax that he definitely knows how to use.
  • Badass Beard: Has a goatee both in real life and in the games, and is one of said games' stronger players.
  • Bald of Awesome: He's virtually hairless, and he's also one of the most powerful players in SAO, if he were to concentrate more on combat.
  • The Bartender: His job in real life is running a bar. He also fits the adviser part of the role both in the game and in real life, by giving advice and operating the Good Guybar.
  • Cool Big Bro: While his closest friendship is with Kirito, Agil is by proxy the caring big-brother to ''his' friends, seeing them also as beloved comrades in arms who have bled together in battle. He regularly holds celebrations on-the-house for his "little brothers and sisters", with the caveat that anyone who isn't Kelin only gets to drink orange/apple juice, being underaged and all.
  • An Entrepreneur Is You: In SAO, he runs a shop on the 50th floor. 2/5 of his 10 Skills are for appraisal and negotiations on pricing items.
  • Gatling Good: In Fatal Bullet, he's one of two heavy weapons specialists among the cast, the other being gameverse original character Strea, included in the game's launch, wielding a gatling gun as a primary weapon, and a rocket launcher as a backup.
  • Genius Bruiser: Big and intelligent in combat. Don't think this salesman is for nothing, he's a tough one.
  • Gentle Giant: Despite how tall and muscular he is, he's still one of Kirito's friends and an overall Nice Guy.
  • Good-Guy Bar: He runs one in both the virtual and real worlds, and in both cases Kirito and his friends hang out there often.
  • Happily Married: In the real world. When he was trapped in SAO, his wife singlehandedly kept his bar running and waited for him to come back, so they could pick up where they left off. He did, and they did.
  • Hidden Heart of Gold: He gives off the image of being a greedy merchant, but in reality, he donates his profits to lower-level players. He's quite surprised when Kirito reveals he knew that.
  • Intergenerational Friendship: Is old enough to be married, yet retains a close friendship with Kirito who is only in his teens.
  • Large and in Charge: In the early days of SAO, he was the de-facto leader of a group of tank players who fought on the fronts lines separate from the Aincrad Liberation Squad and Dragon Knights Brigade, and he was the biggest out of any of them.
  • Let Me Get This Straight...: He more or less summarizes Kibaou's grievances with the beta testers as being over monopolizing resources in a manner similar to this trope, before following up with the fact that because of the beta testers, the rest of the players have access to the most important commodity of all- information:
    "If I have this right, Kibaou, you're claiming that many newbies died because the former beta testers didn't help them, and therefore they should apologize and pay reparations? Is this correct?"
  • Mighty Glacier: Downplayed. While very strong and not especially slow, when he fights alongside Kirito's party he gives the impression of being one likely due to the fact several of his teammates are Lightning Bruisers.
  • Nice Guy: You can never tell from his shop's seemingly unfair trading policies, but Agil is a loving husband and player who spent most of his fortune helping newbies.
  • Online Alias: Agil, taken from the first letter in his given name and the first three letters of his middle name.
  • Our Gnomes Are Weirder: Is a Gnome in ALO, but doesn't appear to resemble anything like the traditional Gnome. He's human height, has no beard, and is naturally very strong. The fact he wields an axe makes him seem more like a dwarf then anything else.
  • Out of Focus: Agil is notably absent for the majority of the Phantom Bullet and Calibur arc, when all of Kirito's other friends are present, with the explanation being he needed to take care of his shop.
  • Real Name as an Alias: Andrew Gilbert Mills, or Agil.
  • "The Reason You Suck" Speech: Gives a minor one to Kibaou when the latter goes into a rant against beta testers, showing him that the free manual handed out to people was written by the same people Kibaou accused of being selfish cheaters.
  • Scary Black Man: Subverted — as intimidating as he looks, he is actually one of the kindest senior players in SAO.
  • Straight Man: Serves as this for Klein, being the more rational voice of reason to Klein's wacky Plucky Comic Relief.
  • Token Minority: He's the only one of Kirito's close SAO friends who isn't a native of Japan.
  • Vitriolic Best Buds: With Kirito. They occasionally playfully bicker, but both have a higher opinion of the other than they let on.
  • Weapon of Choice: Two-handed axes. In SAO, he used the "Ground Gorge".

Click here to see Silica's GGO avatar 

"Pina, I'll be sure to tell you lots and lots of stories. About my amazing adventure today and about the one day in my life that I had a big brother."

A young dagger wielder who befriends Kirito. She was able to befriend an NPC dragon that became her familiar, earning her the title of "Beast Tamer". She later joins ALO as a Cait Sith beast tamer.


  • A-Cup Angst:
    • Shows hints of this in regards to Suguha's bust in the Extra Edition episode.
    • Played straight in the games where Silica is constantly shown to be sensitive to remarks about the size of her bust.
    • In Hollow Fragment, one event had her and Kirito experiencing a status debuff that changed parts of their avatar to out of proportion. For Silica, it was her bust that increased in size and she's secretly delighted, while also trying to hide this fact from Kirito.
    • In Lost Song, she even tries to ask Strea for advice on how to increase the size of her bust.
  • Achievement In Ignorance: She has no idea how she initially acquired Pina as a familiar, as all she did was feed the feathered-dragon some peanuts and it started accompanying her everywhere.
  • Adaptational Badass: While she was much too weak to be part of the Assault Team in canon, in the game adaptation she can accompany Kirito to fight against bosses and can actually be very useful.
  • Adaptational Early Appearance: In canon, aside from an Early-Bird Cameo, she doesn't appear until two years after the launch of SAO. While in Integral Factor she's first seen on Floor 8, prior to her meeting Kirito.
  • Adaptational Wimp: In the light novel, she is among the highest level players outside of the Aincrad frontlinenote  and capable of going solo in a dungeon. The only reason she needed Kirito's help was because she got lost in the Forest of Wandering for hours after the completion of a raid, so she was tired and out of crystals. Her major appearance in the anime's first season, on the other hand, makes it look like her only ability is Pina and that she is helpless without the dragon.
    • Zig-Zagged: During the event where she was constricted by the tentacled plant monster on the way to rescuing Pina: in the novel, she swung her dagger wildly in front of her, activating a Sword Skill and leaving herself wide open. In the anime, she was ambushed by a constricting attack that even Kirito didn't see coming.
  • Ascended Extra: The video games do this for her during the Aincrad arc, with her being sifted from reoccurring character to main cast.
  • The Baby of the Bunch: Silica is doted on and protected by every member of the Heroes of Aincrad like a little sister, by Kirito, Asuna, and Lisbeth in particular, due to her meek and vulnerable personality. Even Yui, who is ostensibly her junior, is braver and more assertive than she is. Silica for her part often feels guilty about this; in particular during the "Ordinal Scale" Motion Picture, her cowardice during a key battle causes Asuna, to shield her from the blow of a resurrected Aincrad boss, was robbed of her 2 years of Memories spent in Aincrad.
  • Badass Adorable: Yes, she's cute as a button, but she's still a competent player for someone as young as her.
  • Bare Your Midriff: Has her first midriff baring main outfit in Fatal Bullet.
  • The Beastmaster: In Both SAO and ALO she works with dragons. Her skills are good enough that she can even befriend non-hostile animal mobs like deer.
  • Bilingual Bonus: Her real given name is Keiko which is Japanese for silicon. This is also what she based her gamer name on.
  • Breakout Character: Silica was a fairly minor character in the Aincrad arc, but was so popular she was promoted to main cast post-Fairy Dance. She along with the other SAO girls feature heavily in merchandising, and she even goes on to star as co-protagonist of the Girls Ops spin-off alongside Lisbeth and Leafa.
  • Butt-Monkey: In her first appearance alone she got her pet killed, nearly answered the door to Kirito in her underwear, and got caught by tentacle monsters far below her level twice. In the Gameverse, she ends up getting assaulted by tentacle monsters or being reminded of lack of assets and in having animal mobs attack her and nearly damage her clothes. Her first scene in Millenium Twilight had her running away from mobs by hiding in a barrel...and then getting stuck and needing help to get out.
  • Casting Gag:
  • Cat Girl: A Cait-Sith beast tamer in ALO.
  • Clingy Jealous Girl: She makes lots of subtle attempts to spend time, get closer, or be affectionate towards Kirito on the hopes that she can win him over.
  • Clothing Damage: Happens in Hollow Fragment, where a really weird scene has Silica trapped by a monster with Naughty Tentacles that also exudes slime that melts armor. Kirito has to free Silica from the monster while trying not to look at her.
  • Color Motif: Averted. She is notably the only one of the main cast who doesn't have one. She has been variably given Yellow, Red, and Blue without any specific fixed color.
  • Cool Big Sis: While she's usually on the receiving end, she does become one to Yui, especially in the game adaptation. When Kirito and Asuna aren't around, Silica is the one most likely of playing with Yui.
  • Crush Blush: In her debut episode, her face keeps flushing red when she's around Kirito, with her trying to dismiss it as the room being hot.
  • Cute, but Cacophonic: Silica loves to sing the songs of the virtual idol Yuna in the Ordinal Scale film; not that she's very competent at it, but hey points for effort.
  • Cute Clumsy Girl: It comes with being an adorable Butt-Monkey. Silica often finds herself as a screw-up much to her embarrassment.
  • The Cutie: In a cast already full of cute girls, Silica is the youngest and most endearing out of all of them, who everyone (In-Universe and Out) dotes on like a little sister.
  • Dangerously Short Skirt: Her Avatar's default outfit has this. On more than one occasion (usually involving tentacle monsters), she has to desperately hold on to prevent a Panty Shot.
  • Demoted to Extra: Only for the Aincrad arc. In the light novels Silica is a supporting character who had multiple stories and run-ins with Kirito, while in the anime she only has one episode focusing on her.
  • Dude Magnet: She gets a lot of party member invites from guys in Aincrad. The narration explicitly calls them "suitors." In Hollow Fragment she reveals she's also gotten numerous in-game marriage proposals before.
  • Early-Bird Cameo: Silica had a very brief cameo during episode 1 with the crowd of players listening to Kayaba's announcement.
  • Everyone's Baby Sister: All of the SAO main cast dote on Silica like a little sister, especially Kirito who has stated she reminds him of Suguha.
  • Famed in Story: She's a celebrity in Aincrad for three reasons: 1) She's a real girl. 2) She's an upper middle level player. 3) She owns a Feather Dragon, an exceedingly rare creature.
  • Feathered Dragons: Pina, her familiar, is a blue Shoulder-Sized Dragon whose species is literally dubbed "Feathered Little Dragon" due to its birdlike wings.
  • Fluffy Tamer: Befriends a Feathery Dragon she names Pina.
  • Girlish Pigtails: Signifying her youth and immaturity.
  • Grow Beyond Their Programming: Familiar algorithms do not provide the option for familiars to physically defend their masters. Pina took a hit for Silica because she wanted to.
  • Head Pet: Her pet dragon Pina tends to rest on her head.
  • Height Angst: Not so much her height itself, but more wanting to grow up. Everyone treats Silica like their kid sister, and at times she gets fed up of this. It's revealed when she first started playing SAO she actually made a mature looking avatar, but was disappointed when it got altered to her young real life appearance.
  • Heroic BSoD: She clearly has one after Pina pulls a Heroic Sacrifice.
  • Hollywood Tone-Deaf: She is certainly an "enthusiastic" fan of the virtual idol Yuna in the Ordinal Scale motion picture, but can't hold a note to save her life, as shown in her adorably-hilarious attempts to imitate Yuna's singing when put on the spot by Liz to do so.
  • Hopeless Suitor: For Kirito. The first time she met him, he was still too shaken over Sachi's death to think about romance. By the time they meet up again, he's in a relationship with Asuna. She still harbors feelings for him years later and still keen on getting close to him, despite her feeling guilt on disrupting his relationship with Asuna.
  • Image Song: She has a total of four. "☆Lovely Super Idol☆", "Party-go-round (Silica & Lisbeth), "Sing All Overtures" (which is sung by Kirito, Asuna, Yui, Leafa, Lisbeth and herself), "Memorial Calibur" (which is sung by Leafa, Yui, Lisbeth and herself).
  • Intellectual Animal: In Memory Defrag, one character story had Silica becoming Thumbelina where she's shrunken down and while in this state she can understand Pina, who reveals she can always understand Silica just fine.
  • Just a Kid: Others keep treating her this way, much to her annoyance. She's also particularly fed up with how she looks so young and wishes more than anything to grow up quicker.
  • Kid Sidekick: She's the only one of Kirito's companions who could pass off as a kid, being at the meager age of thirteen when they first meet.
  • Knife Nut: Uses a dagger as her main weapon.
  • Know When to Fold 'Em: In the manga adaptation of Mother's Rosary, she knows she's outclassed against Yuuki after seeing Leafa lose easily, and so doesn't even try to fight her.
  • Like Brother and Sister: Nearly all of the main cast see Silica like a little sister, but special mention goes to Kirito. Both parties have openly thought of each other as a brother and sister, with Kirito actually coming to Silica's rescue because she reminded him of his real sister, Suguha. While Silica recollected that being with Kirito finally allowed her the experience of having an older brother.
  • Living Emotional Crutch: Pina has useful abilities like detecting monsters or restoring HP, but her greatest value to Silica is as a friend.
  • The Load: Her main role in the Ordinal Scale film consisted of running away from a boss and getting knocked on her back by Eiji which forced Asuna to take the blow for her and loses her memories of Aincrad to show off the villain's plans.
  • Luminescent Blush: Fairly often around Kirito due to her Precocious Crush.
  • Meaningful Name: Her avatar name comes from the fourteenth element Silicon. The bauble-like hair bands represent Oxygen (as in silicon dioxide a.k.a. silica). Why? Her birthdate is October 4th (10/4; since 104 was Rutherfordium, her father added 10 and 4 to get 14: Silicon), and her real name comes from keiso, the Japanese word for Silicon. Kirito figured all that out from the simple hint that "My name comes after Alumi, and before Rin." Silica was shocked.
  • Nice Girl: A kind young lass, whom in spite of her (comparative) weakness and cowardice next to the other heroes of Aincrad, always steps up to take responsibility and stands by her friends when the chips are down.
  • Older Than They Look: Silica is frequently mistaken for a kid, even though she's already in her teens. She's fifteen by the time of SAO II yet still retains a very youthful appearance.
  • Online Alias: Silica.
  • Open Mouth, Insert Foot: Silica lets slip a lot of things that end up embarrassing herself such as the feelings she has for Kirito.
  • Precocious Crush: On Kirito, who's two years her senior. Taken Up to Eleven at the end of the Alicization arc when she took advantage of Kirito's gratitude by hugging him, only to end up getting her tail grabbed by Lisbeth for it.
  • Plucky Girl: After Pina's temporary death, Silica was distraught but never gave up hope that she could save her dragon.
  • Red Baron: In SAO, she is known as "Dragon Master."
  • Red Eyes, Take Warning: Averted. Her online avatar sports red eyes, but she is a kind soul.
  • Replacement Goldfish: She named Pina after her real life cat, not knowing at the time if she could ever get to see the original Pina again. Once she's freed from SAO, Silica desires to have both Pinas meet each other one day.
  • Rescue Romance: Kirito saves her after Pina performs a Heroic Sacrifice, helps her get the resurrection item, and protects her from Titan's Hand. This prompts her attraction to him.
  • Screw This, I'm Outta Here!: She ditches Titan's Hand when she's first introduced because they hogged items.
  • Secret Test of Character: Her bond with Pina is tested out in Hollow Fragment, where she's offered the chance to get a stronger dragon if she were to sacrifice Pina. Silica refuses and in the process reveals her absolute devotion to Pina, with the quest rewarding her by making Pina stronger.
  • She Cleans Up Nicely: In the rare times she lets her hair down, she looks surprisingly mature compared to when she has it in pigtails.
  • Shoulder-Sized Dragon: Pina sometimes perches on her shoulder.
  • Shrinking Violet: She's easily embarrassed and flustered, especially in a romantic situation.
  • Supporting Protagonist: Her introduction arc in Aincrad volume 2 is written from her perspective, but Kirito takes the lead narrative-wise.
  • Thinking Out Loud: Has a tendency to mumble her thoughts aloud, leading to others accidentally overhearing snippets of (at times embarrassing) thoughts.
  • Token Mini-Moe: She's one of the youngest characters in both SAO and ALO, as well as the youngest in Kirito's party, being only at the tender age of twelve at the start of SAO. She's also huggable cute and easily flustered.
  • Weapon of Choice: Daggers, which she first picked due to feeling their light weight would work best for her. In SAO, she is seen using a "Shadow Dagger" before replacing it with an "Ebon Dagger" received from Kirito.
    • In Fatal Bullet, she instead uses a select-fire converted H&K SP89 (Semi-auto only civilian version of the MP5K sub-machine gun).
  • Young Entrepreneur: In Hollow Realization, she eventually follows in Lisbeth's footsteps and opens a meat bun shop, building it from the ground up with input from Lisbeth and Kirito.
  • You Remind Me of X: The reason Kirito saved Silica the first time was because she reminded him of his real sister Suguha.
  • Zettai Ryouiki: Wears thigh-high boots in SAO with a longcoat.

"If your weapons or armor ever need repairs, you know where to go. The Lisbeth Smith Shop awaits your next visit!"

A blacksmith and friend of Asuna. She helped forge both her and Kirito's weapons, while in battle she's a mace wielder. In ALO she joins as a Leprechaun.


  • Adaptational Badass: The game adaptation makes her much stronger around the time of the Aincrad arc, where she sometimes participated in Boss raids with Kirito.
  • Adaptational Early Appearance: Aside from an Early-Bird Cameo, in canon Lisbeth didn't appear until after 2 years of the launch of SAO. In Integral Factor she appears on Floor 4, where at this point she has yet to dye her hair pink and had not yet opened up her Smithing shop.
  • Affectionate Nickname: All her friends call her Liz.
  • Ascended Extra:
    • The video games do this for her during the Aincrad arc, with her being sifted from reoccurring character to main cast.
    • Played with in regards to War of the Underworld anime. While Lisbeth is by no means a minor character, she was largely Out of Focus in the lightnovels for this arc. The anime gives her several prominent moments, including her famous "gamers rise up" Rousing Speech that she gives to the ALO players.
  • Berserk Button: She doesn’t like it when someone insults her skills as a Blacksmith or the way she does business. When Kirito calls her a ‘Rip-Off Blacksmith’, she immediately tries to punch him!
  • Best Friend: She was one of Asuna's closest friends in SAO and remained as one of the few she had before their social circle expanded.
  • The Blacksmith: She personally made Asuna's rapier "Lambent Light" and Kirito's secondary straight sword "Dark Repulser." This continues in ALO where she's the gang's official blacksmith, making Kirito's sword there as well as virtually everyone else's weapons that are better than quest rewards, including some of Sinon's bows. She also handles repairing everyone's gear there as well.
  • Brainy Brunette: Her hair is naturally brown, and she's smart enough to successfully run her own business.
  • Breakout Character: Lisbeth was a fairly minor character in the Aincrad arc, but her popularity had her promoted to main cast post-Fairy Dance. She along with the other SAO girls feature heavily in merchandising, and she even goes on to star as co-protagonist of the Girls Ops spin-off alongside Silica and Leafa.
  • Cannot Spit It Out: Never manages to directly tell Kirito about her feelings. Kirito catches on the gist of it from her embarrassed stuttering and turns extremely embarrassed himself upon realizing it.
  • Carry a Big Stick: She wields maces when she fights.
  • Character Exaggeration: Lisbeth's a far bigger troll in the game adaptations with her Clingy Jealous Girl traits being played up far more. She's far more inclined to make moves on Kirito whenever even the slightest opportunity presents itself that he and Asuna may be loosening up.
  • Clingy Jealous Girl:
    • Despite supporting their relationship, she gets angry when she sees Kirito and Asuna getting lovey-dovey.
    • Post-Alicization, she grabs Silica's tail out of jealousy when the latter is making an excuse to hug Kirito.
  • Color Motif: Her in-game avatar has pink hair, while in the real world she tends to wear a pink skivvy.
  • Cool Big Sis: Develops into one towards Silica after they meet up. They're often seen together both in and out of virtual reality, with Silica often confiding to her. In the game adaptation, she outright says she considers Silica to be her kid sister. During Hollow Realization, Lisbeth gives her input to help Silica start her own business.
  • Covert Pervert: Hollow Fragment seems to depict her as one. In one scene where they bathe in some hot springs, she makes it clear that Kirito isn't to peak on her but gets the temptation on peaking on him herself. She then accidentally invites Kirito to visit a real life hot spring with her, making it sound like she's asking Kirito out on a date, but luckily Kirito doesn't pick up on this and suggests all of their friends go together.
  • Crazy-Prepared: As revealed in Girls' Ops, she carries a portable anvil and her blacksmith hammer in her inventory in case she needs to repair weapons on the fly.
  • Curtains Match the Window: Both in real life and her in-game avatar, her eyes and hair are the same color (brown in real life, pink in-game).
  • Famed in Story: She's well known in Aincrad as an Ultimate Blacksmith, a Mace Master, and of course a real girl.
  • Fire-Forged Friendship: She and Kirito don't get off to a good start with him breaking her best sword while trying to test its durability. However going on a quest with Kirito and having him go out of his way to keep her safe wins over her trust and they become good friends.
  • "Freaky Friday" Flip: In Hollow Realization she somehow swaps avatars with Leafa. She's very annoyed by the development and finds Leafa (as Lisbeth) using her avatar to extort information from Kirito about what he thinks about her (Leafa). Kirito never realizes what's going on.
  • Early-Bird Cameo: She's easy to miss, but she appears in the first episode as part of the large group of people listening to Kayaba's announcement. She also had her real life hair color back then before it was customized pink in-game.
  • Deadpan Snarker: She was the major source of snark before Sinon showed up, often showing exasperation with Kirito's antics and mercilessly ripping into Kirito and Asuna's more affectionate moments.
  • Drop the Hammer: Happens on a daily basis, as she's constantly beating metal into weapons and armor. She also occasionally wields one in combat, and currently possesses Thor's hammer, Mjölnir, one of the legendary weapons in ALO.
  • The Gadfly:
    • Lisbeth is particularly fond of teasing Kirito and Asuna about their relationship.
    • Even more so in the non-canon games where she has a tendency to put them in embarrassing situations. She's also not above making sneaky attempts to make moves on Kirito or get intimate with him while Asuna is in the room.
  • Get a Room!: Lisbeth will often give this type of response when Kirito and Asuna start getting too lovey-dovey.
  • Glass Cannon: Originally, her weapons focused on sharpness and quickness, while largely ignoring durability. After Kirito effortlessly destroyed her best sword, she realized that in a desperate situation, what could ultimately save the lives of her clients is the weapon's durability.
  • Honest Axe: In Hollow Realization, one quest had Lisbeth reenacting this fable, only with the ax replaced with her blacksmith hammer. While Lisbeth plays out most of the story the same way, by being honest to the forest spirit and admitting her real hammer was not the gold or silver one, but her iron one, before being rewarded both hammers for her honesty. However after acquiring said precious hammers and feeling how heavy they were, she further adds that she felt wasn't ready yet for said hammers and thought it better she stuck to her original one. The forest spirit is amazed by her level of honesty and as a further reward decides to enchant her original iron hammer to maximum efficiency which Liz overjoyed by.
  • Image Song: She has a total of four. "Cheer! Tear? Cheer!!", "Party-go-round" (Silica & Lisbeth), "Sing All Overtures" (which is sung by Kirito, Asuna, Yui, Leafa, Silica and herself), "Memorial Calibur" (which is sung by Leafa, Yui, Silica and herself).
  • Insane Troll Logic: While waiting for Kirito to bring Sinon to the Dicey cafe, Lisbeth ate two slices of apple pie and states it's Kirito's fault if she gains weight.
  • Leprechaun: Her character race in ALO. It just so happens that Leprechauns are skilled at tinkering and smithing, receiving bonus skills in them as a race of ALO (they even get mechanical wings, rather than the normal fairy wings).
  • Male Gaze: On Asuna's advice she started wearing a cuter outfit as part of her blacksmith attire, which actually resembles a waitress outfit. Her shop immediately became more popular.
  • Named Weapon: In ALO, Klein gave her the legendary hammer, Mjölnir, on the condition that she will not break it down into Orihalcon ingots.
  • Online Alias: Lisbeth.
  • Platonic Life-Partners: Has this dynamic with Kirito. Although she does personally have feelings for him, she has accepted that he will always be with Asuna. Nevertheless the two are very close friends.
  • Plucky Girl: Despite losing Kirito to Asuna, Rika still cheers for the two of them.
  • Pretty in Mink: Has a fancy fur lined cape she wears for cold weather.
  • The Protagonist: Her introduction arc in Aincrad volume 2 is from her perspective and she is a first person narrator.
  • Rose-Haired Sweetie: Her avatars in SAO and ALO have pink hair, fitting her cheerful personality.
  • Secret Keeper: In SAO, she was the only person to whom Kirito had revealed his Dual Wielding Unique Skill prior to him being forced to go public with it.
  • Shipper on Deck: When she's not being envious, she openly supports Asuna and Kirito in their relationship.
  • Shotguns Are Just Better: When playing GGO, she's arming herself with a Benelli M3 Kromo semi-automatic shotgun.
  • Skinship Grope:
    • Seems to really enjoy doing this to Suguha/Leafa, for a couple of obvious reasons. Does it at least twice, once in real life during the recap special at the pool with Suguha in her School Swimsuit, and once in ALO in the Girls Ops manga, at the beach, with a Wardrobe Malfunction.
    • She also does this to Silica's Cait-Sith ears in the games, to the point where the latter feels its sexual harassment, before Yui clarifies it would not fall under the act due to both of them being females.
  • Snark-to-Snark Combat: Before Sinon showed up, she was the one to provide this dynamic with Kirito, constantly teasing him and getting under his skin for fun.
  • Spell My Name with an "S": Official spelling for her name is "Lisbeth", but sometimes "Lizbeth" will pop up in translations.
  • Stealing the Credit: When discussing how to fix their clothes with Lux and Silica after they were nearly destroyed by slimes, she mentions learning that Ashley, a player from SAO who maxed out her Sewing skill, was playing ALO from Asuna. Due to her wording, Silica immediately calls her out on the fact that it was Asuna who learned of this helpful information.
  • Switching P.O.V.: Is the narrator of her story in Volume 2, and a short scene in Volume 4.
  • Sweet Tooth: Lisbeth has a quite a sweet tooth and loves gorging herself on cakes, especially given the fact she can eat all she likes in VR without having to worry about getting fat.
  • Tsundere: Of the "dere" type. Although usually cheerful and easy-going, she can be very quick to snap at the most trivial things (usually involving Kirito) and is not above using violence. At one point she actually attempts to punch Kirito for calling her a "rip-off blacksmith".
  • Ultimate Blacksmith: She's maxed out her blacksmithing skills, allowing her to craft any weapon including legendary ones.
  • Weapon of Choice:
    • One-handed maces with a buckler, likely due to their similarity to a hammer which she typically works with as a blacksmith.
    • In Fatal Bullet, she uses shotguns instead, in particular the Benelli M3 pump/semi-auto shotgun.
  • Weak, but Skilled: Compared to Kirito her STR parameter is far lower and she often has trouble lifting weapons he carries with ease, but she's still a master macer and an Ultimate Blacksmith.
  • "World of Cardboard" Speech: Gives an epic one in response to a Salamander Commandernote  trying the deliver a "Reason You Suck" Speech over her plea for help to save the Underworld and the Artificial Fluctlights in it being unreasonable and accusing her, as an SAO Survivor, of looking down on other players and dragging the real world into the game.
    “That's right, this is happening in the real world! Like you said, those of us who came from SAO might have a tendency to blur what's real and what's virtual! But I swear to you, we don't think of ourselves as heroes, or anything special! [Silica] and I... we attend a school made up of only survivors. The students there have to undergo counselling once a month, no matter what. We get asked all these uncomfortable questions. And they make a lot of kids take meds against their will. We're all part of the government's potential criminal watch list. And it's not just students at the returness school who are being treated that way. VRMMO players are looked upon that way, more or less. As if we're dead weight that doesn't contribute to society. People who refuse to face up to reality, not paying taxes or social security. Some people even argue that military draft should be reinstated, so we can be forced to serve. But there's one thing I know! And I believe it! That reality is right here! This world, as well as the countless virtual worlds connected to it, in no way are they make-believe refuges! For me, this world is the reality where I have a real life, real friends, real encounter and partings, and real smiles and tears! Don't you all feel the same way? Aren't you all doing your best because this is your alternate reality? And yet, if it's just a game, if you abandon it because it's nothing but a virtual fake, then tell me, where is our truth!? All these worlds that we've grown came together like this World Tree and started to bud. And caused this flower called the Underworld to bloom. Well, I want to protect it. Please! Please... help us.
  • You Gotta Have Blue Hair: Dyes her hair pink in SAO after she starts blacksmithing (a group photo on her wall reveals her with naturally brown hair).
  • Young Entrepreneur: In SAO, she built her blacksmithing business from the ground up.
  • Youthful Freckles: One of the few characters to have them, alluding to her can-do personality.
  • Zettai Ryouiki: Wears this in her school uniform IRL.

    Yui 

Yui (SAO, ALO, OS, UR)

Voiced by: Kanae Ito (Japanese), Stephanie Sheh (English), Susana Moreno (Latin American Spanish), Nina Romero (European Spanish)

Click here to see Yui as a Navigation Pixie in ALO 

"I... I... I want to always be with you."

An AI in SAO created to take care of the mental health of the players but was suspended by the Cardinal system when the death game began. Unfortunately her monitoring operations continued and sensed the negative emotions such as fear, despair, rage, and madness from the players. Unable to perform her duty due to her restriction, she broke down due to errors. When she sensed Asuna and Kirito's more positive emotions, she was overcome with the urge to see them, which then kicked off the events of Morning Dew Girl and later made her their adoptive daughter.


  • Amnesiacs are Innocent: The girl who has no memory also doesn't have a care in the world.
  • Artificial Intelligence: A Top-Down AI.
  • Back from the Dead: Kirito manages to save her information before she's deleted from the system, and successfully brings her back in ALO.
  • Badass Adorable: Cute and sweet, not to mention she actually cares about the players in the game worlds she's assigned (it's her job to begin with). But try to threaten those she care about (i.e. her adopted mom and dad), she will conjure up a sword made of fire (or any weapon of mass destruction) and utterly erase you from existence, even if you are a nigh-invulnerable boss monster. In short, do not taunt the happy fun admin.
  • Become a Real Boy: Yui is an AI designed to be a Mental Health Counselling Program, and was designed to be able to do no more than to monitor the mental state of players and help them out when required. She was however given emotion to help her understand them better. Despite being an AI, she somehow manages to gain desires to meet Kirito and Asuna, being drawn towards their joy and love. Yui herself remarks that this wasn't supposed to be possible since she was just a program, but it still happened anyway. As she had broken free of cardinal and no longer was under its control, and living with Kirito and Asuna allowed her to became more and more human. Once free she is able to officially accept Kirito and Asuna as her parents.
  • Beware the Nice Ones: The Fatal Scythe learned the hard way not to endanger her parents, when she uses her admin powers to summon an Infinity +1 Sword and deletes it.
  • Bizarre Taste in Food: Like father like daughter. She inherits Kirito's fondness for spicy food.
  • Brains and Brawn: The brains to Strea's brawn. Among the two AI sisters, Yui is The Smart Gal for the team serving as Ms. Exposition, while Strea is The Big Gal being a tank who is extremely efficient in battle.
  • Casting Gag: Stephanie Sheh also voiced another adorable Yui.
  • Cheerful A.I.: As a Mental Health Counselling Program, Yui was programmed to emulate emotions and presents herself as a Cheerful Child.
  • Cheerful Child: Sweet and adorable, Yui's sunny disposition lifts everyone's spirits.
  • Children Are Innocent: Yui is a very well behaved daughter who tries everything she can to please her parents. She's also Constantly Curious and full of questions, sometimes into sensitive topics that a girl her age are not yet ready for.
  • Clingy Jealous Girl: Claims only she and Asuna can hug "Papa" when Kirito first meets Leafa after the latter thanks him for rescuing her. She in general reacts poorly to other girls getting too clingy with him, but it's clear she only wants to make sure he stays faithful to Asuna.
  • Constantly Curious: One of her defining traits in the game continuity is her never ending curiosity. Whenever she hears about a new word or concept, she will endlessly pursue for explanation until she gets a satisfactory answer. This has led to a lot of trouble when the topic is a bit too embarrassing or inappropriate to talk with a child. For instance, Yui was very persistent with how babies are made in the real world, trying to get Kirito and Asuna to give her The Talk.
  • Cool Big Sis: Ironically to Strea in the game adaptation, who is technically Yui's little sister. Despite Strea being physically much bigger than Yui, she is even more childish and immature which leads Yui to teach and discipline Strea.
  • Daddy's Girl: To her Daddy Kirito, particularly in the ALO arc, because she has more screentime than in Aincrad and so more time to be affectionate.
  • Damsel in Distress: The main plot of Accel World VS Sword Art Online is Yui getting kidnapped by Persona Vabel, where Kirito, Asuna and everyone else attempt to rescue her. It gets more complicated when it's revealed Vabel is actually her from 1000 years into the future and wants to erase Yui (and by extension, herself) from existence so Yui won't outlive Kirito and Asuna, so that Vabel herself can finally put herself out of her misery.
  • DePower: In SAO she was a system admin, but in ALO, she's no longer connected to the Cardinal system and so she no longer automatically has admin abilities. Though she DOES however have the admin passwords, and can still see the source code which allows her to provide info.
  • Does Not Like Shoes: Goes barefoot both in human and pixie forms, seemingly as part of her standard equipment in the first and as a trait of her Navigation Pixie official attire in the second. It also might be out of personal preference, given her innocent child status. This is later averted in Unital Ring, where she Took a Level in Badass through combat lessons from Alice and started to wear boots.
  • Dragon Rider: A very unusual example. As a Navigation Pixie, Yui frequently rides the Shoulder-Sized Dragon Pina.
  • The Empath: Due to being programmed as a therapist, she is extremely compassionate and in-tune with the emotions of those around her. Near the end of her introductory arc, she is able to casually push a girl she just met towards confessing her feelings towards her guild leader.
  • Exposition Fairy: In ALO, she's a Navigation Pixie designed to provides players with intel.
  • Fading Away: Just before she gets deleted by Cardinal for disobeying her programming, she starts fading away, with just enough time to share a last hug with Asuna while telling her to keep on inspiring hope in others. Fortunately, before she's gone for good, Kirito manages to save her data as an in-game item.
  • Fairy Companion: In ALO, she becomes a "Navigation Pixie."
  • Flaming Sword: A giant one that she conjures up to save Kirito and Asuna from a Level 90 Boss Monster.
  • Flower in Her Hair: As a Navigation Pixie in ALO, she wears a blue flower in her hair.
  • A Form You Are Comfortable With: Technically, since she's an AI, her true form is not the cute kid that looks like a hypothetical child of Asuna and Kirito. Though admittedly, It might as well be nowadays.
  • Fun Size: Upon entering ALO, she adopts this size (and poses as a Navi Fairy) for ease of travel (in Kirito's shirt pocket) and the better to not rouse the suspicion of the reigning computer system.
  • A Glitch in the Matrix: She causes one of these in SAO. When she screams, the area bugs out briefly.
  • Grow Beyond Their Programming: While MHCP's are designed with emotions so they can better understand and help players, they are not supposed to be able to form attachments to humans. Yui managed to develop feelings of affection for Kirito and Asuna all on her own.
  • Go Out with a Smile: She smiles sweetly as she gets deleted by Cardinal. Though fortunately she isn't gone for good as Kirito manages to use his hacking skills to save her data.
  • Happily Adopted: When Kirito and Asuna found her wandering around a forest, they initially planned to find her parents. In the end, they became her parents, to the delight of everyone involved.
  • The Heart: She was originally designed to maintain the mental health of the players by giving them emotional support. Unfortunately, when the death game began, she was suspended by the Cardinal system and was forced to watch the players commit suicide and kill each other out of fear, anger, and despair. Then, she came across Kirito and Asuna.
  • Heroic Sacrifice: Seeing Kirito and Asuna in trouble while fighting the Fatal Scythe, Yui hacks a nearby GM console to summon the "Object Eraser" to delete the boss. However she knew fully well that in doing so she would be detected by Cardinal and deleted as a foreign object. Fortunately Kirito is able to save her in time and convert her data into an in-game item for later restoring.
  • Image Song: She has a total of four. "I Know "Ai"", "Heart Sweet Heart", "Sing All Overtures" (which is sung by Kirito, Asuna, Silica, Leafa, Lisbeth and herself), "Memorial Calibur" (which is sung by Leafa, Silica, Lisbeth and herself).
  • Infinity +1 Sword: She conjures up one called the "Object Eraser" to annihilate in one hit the most powerful boss in the game.
  • The Informant: Her main role post-Aincrad is to use her nature as an AI to give intel into the system for Kirito and the other players, providing valuable information on monsters and NPCs.
  • Innocent Fanservice Girl:
    • In Sword Art Offline, at one point she went on a trip with Asuna to a hotspring, during which she took a photo while they were bathing. Yui is unable to understand why Asuna was so embarrassed by this. When it plays on the monitor, Asuna knocks out both Kirito and Klein to keep them from watching before cutting to the next scene, to Yui's confusion.
    • She also has shades of this in Hollow Fragment. While she typically dresses appropriately, she doesn't have an understanding of covering up while bathing. She jumps up excitedly while in the hot spring, with her Modesty Towel at risk of falling off, to the concern of Asuna. She's just a little kid, after all (or a program with the mentality of one).
  • Instant A.I.: Just Add Water!: She starts off as a mental health counseling program, then she develops real emotions and becomes closer to a human.
  • Is That Cute Kid Yours?: Played with. People often get confused over how people as young as Kirito and Asuna are able to have a daughter as old as Yui due to misinterpreting that she is their biological daughter. Only when Kirito and Asuna clarify that Yui is their adoptive daughter does the misconception get cleared up.
  • Japanese Honorifics: While Yui uses these for virtually everyone (except Strea once they are revealed to be sisters), what's even more notable is she is the one character who everyone addresses with a "-chan" honorific, including characters who don't usually use these. Even Kirito asked for Yui's express permission before addressing her just by name.
  • Killer Rabbit: In SAO she looks like an ordinary, cute child and then she one-shotted a Floor-90 boss. Just to be clear, the population didn't get above Floor 75. She regained some of her Badass Adorable creds later in Unital Ring.
  • Let's Get Dangerous!: Thought Yui was just a helpless little girl that needed protecting? Nope, she was able to summon up a Infinity +1 Sword and One-Hit Kill a boss.
  • Light Is Good: In line with her purity and innocence, Yui's outfits are predominantly white. Bonus points for going barefoot.
  • Living Lie Detector: She can easily tell when someone is lying, probably in order to help her do her job better.
  • Magical Barefooter: She always goes barefoot and it's revealed she isn't human but an AI who looks like a little girl. She literally becomes one in ALO as a Navigation Pixie, which would count as a magical creature.
  • Moment Killer: She's unwittingly interrupted Kirito and Asuna's moments a few times, with one of the most notable ones in Ordinal Scale where she interrupts a kiss her parents were able to share to point out a shower of shooting stars in the sky.
  • Ms. Exposition: Aside from the other female leads, Yui is typically the go to character on how a new game works and is the most frequent giver of Info Dumps. In Hollow Realization she's even a literal tutorial NPC.
  • My Instincts Are Showing: As explained by Kazuto in Aliciziation Beginning, there are moments when her nature as an artificial intelligence becomes especially obvious. Her human behaviors are based on what she has observed and there are limits to what she can mimic. Kazuto uses her to contrast fluctlight-based A.I.s which have inherent behaviors and responses and thus are fundamentally the same as human minds.
  • My Sensors Indicate You Want to Tap That: She knows about Recon's crush on Leafa, again because of her ability to sense emotions.
  • My Sister Is Off-Limits!: A rare example where it's a daughter acting this way towards her father. As a result of Kirito being an Adoptive Peer Parent who is still under aged, many girls still try to make a move on him, but Yui does not allow it and insists Asuna is the only one who can touch him.
  • Mystical Waif: At first appearing to be a helpless young girl wandering in the woods, Kirito and Asuna quickly discover she has hidden powers, as the game marks her as "immortal" and she is able to kill a dungeon boss that had downed both of them.
  • Nice Girl: She is literally made to be an emotionally healing outlet of grief, sadness and anger; but like daughter like mom all the same.
  • Not Quite Dead: She hacked into the system using a GM console in order to delete the Fatal Scythe boss and save Kirito and Asuna. However by doing so the system identified her as foreign and proceeded to delete her. However Kirito is able to use the admin privileges of the console to save her data as an in-game item so she can be revived at a later time.
  • O.O.C. Is Serious Business: When Yui regains her memories and is on the verge of being deleted, she drops her usual innocent child persona and becomes unsettling mature and serious, recognizing she isn't human and is actually an AI. However she reverts back to her usual self after expressing her desires to be Kirito and Asuna's real daughter.
  • Our Phlebotinum Child: The love between Kirito and Asuna brought her into existing in the main game world.
  • Our Pixies Are Different: As a Navigation Pixie, she's tiny in stature and able to fit into one's hand, wears a small white flower ornamented dress and is barefoot. Being far smaller than the other human sized fairy races.
  • Power Floats: When confronting the Fatal Scythe and revealing her true nature, she floats in the air as she summons up the Object Erase to delete it.
  • Promoted to Playable:
    • In previous games Yui was always exclusively an NPC, but Accel World vs Sword Art Online: Millennium Twilight finally had her playable as Persona Vabel.
    • In the mobile game Memory Defrag, one of the biggest differences from other games is Yui is playable from the get-go. The In-Universe explanation is an early story event converted her to a combat capable avatar. Although she still has the physical appearance and abilities of a child, which leads her to feel she's not useful.
  • Rapunzel Hair: Like mother like daughter, her hair is waist length.
  • Ridiculously Human Robot: She wouldn't be a very effective therapy bot if she was obviously inhuman.
  • She Is All Grown Up:
    • In Accel World vs Sword Art Online: Millennium Twilight. Unfortunately, in that world at least, she's far from the kind girl that she was in her 'childhood', and only superficially resembles either of her parents.
    • In Fatal Bullet, regular Yui shows signs of growing up. She now has a visible bosom, while being noticeably taller and maturer.
  • Shoulder Teammate: As a Navigation Pixie, one of Yui's favorite places to sit is on Kirito or Asuna's shoulder, either that or she serves as a Head Pet.
  • Siblings Wanted: She shows shades of this in Hollow Fragment, desiring to have a little sister to play with, as she feels lonely when Kirito and Asuna are out clearing bosses. She ends up getting her wish in the form of Strea, who is technically Yui's younger (albeit larger) sister with the two of them showing an unbreakable sisterly bond.
  • Skinship Grope: In one optional even in Hollow Fragment, Klein tells her that boobs are something that every man wants. She proceeds to ask Kirito whose boobs are the best and fondles all of the girls to help with research.
  • Sole Survivor: In Accel World VS Sword Art Online, it's revealed Yui is the last of the pixie race that once populated ALO. They were wiped out by the system after there was no longer a need for Navigation Pixies, leaving Yui as the last one.
  • Spared by the Adaptation: Granted, Yui didn't stay dead (being revived in Alfheim by Kirito), but the game universe (specifically Infinity Moment/Hollow Fragment) reveals that Yui is still alive and well even after floor 75 (The final floor of the original Aincrad arc).
  • Strong Family Resemblance: She looks weirdly like a child Asuna with Kirito's hair color. She even has a similar hair style to Asuna, making her being their "daughter" ironic. This may mean she purposefully or subconsciously sculpted her avatar to look like that when she broke out of Cardinal to find them. Although it's not brought up in the main series, Kirito and Asuna do notice this in Hollow Fragment.
  • Super Senses: As an AI she can see the source code underpinning everything in the virtual world, being capable of telling when players or monsters are near, if a character is an NPC, or when a boss monster is about to attack.
  • Tag Along Kid: Joins Kirito and Asuna in their adventures, even though physically appearing as a young girl.
  • The Talk: Outside of the main series, Yui has tried several times to find out how babies are made, but Kirito and Asuna always decide that she's too young to find out the truth and avoid telling her the real answer.
    • In Sword Art Offline, Yui asks this question to Klein, who defects it onto Asuna. She begins by explaining it involves turning off the ethics code, before Kirito cuts in and covers it up with the Delivery Stork story.
    • In Hollow Fragment, several players were under the impression that Yui was Kirito and Asuna's real daughter before finding out they adopted her. However, this led to Yui being curious on how babies were made in the real world. Asuna explains that creating a child requires a "joint project" from both parents, but when Yui presses for details she lies by telling her it's through kissing. This later comes back to bite her hard when Yui catches Kirito and Asuna kissing. They then have to explain the previous answer wasn't quite accurate and there's more to it then kissing, but also emphasize that Yui is too young to know the embarrassing truth.
  • Technopathy: As an AI, Yui is able to interface with technology and has a degree of control at times. She can hack into security camera footage, operate monitors and displays, and gather intel.
  • There Are No Therapists: Invoked. Yui was designed to be a sort of therapist for players in SAO, but the system prevented her from doing her job. Needless to say, this caused a lot of problems for both her and the players she was unable to help.
  • Token Mini-Moe: Serves this role with Silica, being the excessively young member of the main cast. In this case, she's helping her parents.
  • Token Super: If Kirito isn't deemed super enough, than Yui certainly is. She's a Benevolent A.I. with administrator powers so she could instant kill any unbeatable boss in the game, along with being an Immortal Object that couldn't be destroyed conventionally. In fact, in the Aincrad arc she became a case of Too Powerful to Live and was kinda-sorta deleted. She was only able to return after a depowering, but even so she was able to use her AI nature to see the code that underpinned monsters and NPCs enabling her to provide valuable information. Then it's revealed she even displays a degree of technopathy, being able to hack into security camera footage and top secret data storage to pull out information.
  • Took a Level in Badass: In Unital Ring, Yui gains some combat experience by sparring with Alice.
  • You Called Me "X"; It Must Be Serious: After initially having difficulty saying Kirito and Asuna's names, she resorted to calling them "Papa" and "Mama". It's later revealed this was due to a case of Identity Amnesia. Once she regains her memories of her true nature being an AI and is on the verge of being deleted, she refers to Kirito and Asuna by their proper names much to their surprise. However, almost immediately, she goes straight back to calling them Papa and Mama, as she now truly saw them as her parents.
  • Vague Age: She looks like a young girl under the age of ten, but given she's actually an AI created at an unknown date then it's really not clear how old she actually is.
  • What Measure Is a Non-Human?: AI or human, adopted or biological, Kirito and Asuna consider Yui to be their real daughter. Kirito's ultimate goal is to break down the barriers between the virtual and real world so that Yui can become their true daughter.
  • Wise Beyond Her Years: As an AI, Yui possesses far more knowledge than a girl of her age should, being able to provide encyclopedic info dumps whenever the time calls for it.
