Real world names are in western naming order. Followed by their online name and worlds they played in.note If only the online name is known, then display as normal.
Work in progress due to Loads and Loads of Characters.Note: Unmarked spoilers ahead. Maaaajor major spoilers. If you're starting the anime, do not read this page!note I mean it! Spoiled twists ahoy! Why are you still reading this note? Close the page already! Unless you're a Spoiler Hound, in which case never mind.
The Ace: Out of all 10,000 players, Kirito is the most skilled fighter of all, able to do feats that nobody else can, and is nearly unbeatable in battle.
Broken Ace: Especally during the Aincrad arc, Kirito has alot of issues. Before entering the game, he was a little bit sheltered, partly due to his insecurity of his place in his adopted family, which made him have some poor social skills. But once in the game, he gets a heavy survivors guilt because of the Black Moon Cat guild event. Not only that, he's drone to severe It's All My Fault and he has issues with some of the things he's done. He grows out of it in the Ahlfhiem arc but there are shades of it still.
Aloof Big Brother: He distanced himself from his adoptive sister/cousin Suguha after he found out they weren't real siblings. After SAO he worked to repair the distance.
Anti-Hero: At his worst he's willing to do what it takes to survive.
Attack Its Weak Point/Breakable Weapons: Specializes in this. Asuna notes that in SAO/ALO, Kirito's fighting style focuses on targeting enemy weak points and their weapons, and is called Arms Blast, an Outside System Skill. In ALO, this led to the creation of another Outside System Skill, Spell Blast, where he accurately targets the tiny core in the middle of spells and destroys them.
Awesome but Impractical: In SAO, he's still using and upgrading Dark Repulser months after Liz crafted it for him. As Liz noted, its rapidly being outclassed and a moderately upgraded rare weapon from the 70th floor could match the nearly fully upgraded Dark Repulser, with much less materials per upgrade being spent. The reason is because of its name, Kirito believes that he is destined to use it on the 100th floor final boss. He's right.
Badass: You have to be one to survive as a front-line solo player in SAO. His badassery doesn't decrease in ALO or GGO.
Badass Adorable: Awww, he's so cute—wait, he's what?! The strongest player in SAO?!
The Berserker: His use of Dual Blades skill makes him seem like one. Actually, whenever he gets really serious in a fight. Lampshaded by himself in episode 19. Biggest example during the Alfeim Arc when he transforms him self into a demonic looking monster that allows him to use his claws to fight and kill, not to mention eating some of his opponents.
And, in the battle against the murderers guild Laughing Coffin, Kirito actually kills two of the murderers who would not surrender. Which is fully justified, but still comes back to haunt him.
Also near the end of the Fairy Dance arc or episode 24-25 of the anime. You should see how many pieces of the person who tried to rape the love-of-his-life remain after Kirito's done with him.
Big Brother Instinct: Towards Suguha. He even helps Silica revive Pina because she reminds him of Suguha.
Bishōnen: Applies to his IRL self as well, but it should be noted that its due to being essentially stuck in a coma for two years and is still recovering. Sinon realizes this, so she never makes fun of him for looking so effeminate.
BFS: In ALO the second sword he owned is almost as big as his character, though it's more of a longsword.
Black Swords Are Better: In SAO, his primary weapon "Elucidator"; In ALO, a BFS that replaced his starter weapon; In GGO, a "Kagemitsu G4" lightsaber whose hilt is black.
Character Development: In ALO, he's more confident and lighthearted despite having lost Asuna. Of course, this may have to do with the fact that he can actually play ALO like a game, instead of having to watch people actually die all the time.
Chick Magnet: Oh yes. Plenty of girls flock to him, though it's a bit better handled than other harem series.
The Chosen One: An unusual and indirect example, but his Dual Blade skill was programed by Kayaba to go to whichever player had the fastest natural reaction time, with the intent of making him or her be the one to face his him as the final boss...and it just so happened to be Kirito. Which makes this a rare example of the The Chosen One being chosen by the villain.
Color Motif: He's always related to the black color. Even Asuna says as a joke at one point that she should party with him "because her horoscope said black was her lucky color that week". Blue usually acts as his secondary color.
Cute Bruiser: His appearance is so feminine it causes him to swear off metal armor, and more than one foe comments "he doesn't look very strong"... yet he becomes the strongest player in SAO, and ALO, and ties in the third main tournament of GGO, AND apparently does quite a bit in the Underworld. Not to mention the skills he learn while playing MMOs actually transfers to real life. Just ask idiotic psychopath Sugou.
Cynicism Catalyst: Kirito became a loner after he lost all the members of the "Black Cats of the Full Moon" and failed to revive Sachi. He blames himself for their deaths and avoids people because he's afraid of losing those close to him again.
Despair Event Horizon: Almost crossed it when he managed to obtain a resurrection item to revive Sachi with (on Christmas Eve, no less) and went suicidal after finding out that it doesn't work the way he thought it would.
He gets better only to cross it again when he sees his Second Love struck down in front of him.
Determinator: Shows this trait from time to time. Best example is the climax of Volume 1, where, despite being killed by Kayaba, he holds on long enough to return the favour.
Difficult, But Awesome: So many that only the outstanding examples will be listed here. Dual Wielding without system assist. Blocking bullets. Chaining together one-handed Sword Skills (he has to start one sword skill within a 1/10 second window, in order to stop himself from freezing, basically a Combo of Combos). Spell Blast (using a system-controlled Sword Skill precisely enough to strike down fast-moving spells, which have a miniscule hitbox).
Dual Wielding: The only SAO player who has the Dual Blades Sword Skills.
In later game worlds, he rarely does this anymore... but whenever he breaks out two swords, much awesomeness will occur. The best part? He's physically controlling two different swords without any System Assist.
It's seen quite well in the sidestory Caliber. There are no Dual Blade sword skills... but he has two swords in two hands, so he chains separate one-handed sword skills, controlling each hand separately.
Dude Looks Like a Lady: His avatar in GGO, a rare M9000 type which turned his already feminine looks Up to Eleven. When he saw his own reflection in-game, he thought his gender was swapped. He looked so much like a girl that his IRL friends recognized him not because of his face nor his name, but by his sword style.
Escapism: Done subtly, but like Yuuki, Kirito embraces VR and is deeply immersed in it, to the point where he's preferring VR over reality. Yuuki realizes this and warns Asuna to watch out for Kirito, though Asuna didn't understand what she was talking about.
Face Plant: Happens to him several times when trying to get the hang of ALO's flight engine in the first episode of the ALFheim Online arc in the anime. One pretty spectacular one has him slamming into the ground head-first from several hundred feet in the air and seemingly being stuck for almost a minute after impact.
Glass Cannon: When he whips out Dual Wielding, he gains a completely massive attack output that outstrips everyone in the game. However he basically becomes The Berserker and give up virtually all forms of defense.
Heroic BSOD: Suffers a major one when he encounters Death Gun and realizes that not only is he a survivor of SAO, but also a member of Laughing Coffin. All of Kirito's repressed memories of his participation in the crusade against Laughing Coffin returned and left him in such a wrecked state that Sinon was worried what had happened to him.
Before that, however, he suffers a huge one when Asuna performs a Heroic Sacrifice. It debilitates him so badly that he can't bring himself to do more than slowly and feebly swing his swords at Heathcliff for a few seconds.
Hope Spot: The aforementioned resurrection item, the Stone of Returning Soul. It only works within ten seconds of a player's death, making it utterly useless for reviving Sachi, who died months ago.
Hot Dad: To the AI Yui, who essentially adopted him and Asuna as parents.
I Know Mortal Kombat: At the beginning of Fairy Dance, Kirito proves that he has real-world reaction and dodging speed on par with his cousin, the kendo expert. At the end of the arc, he finally realizes that he can beat an incompetent, wounded, poor fighter, despite the fighter having a knife.
I Don't Know Mortal Kombat: In the same battle, at the beginning of Fairy Dance, Kirito proves very clearly that Sword Skills DO NOT WORK in the real world. Seems he really needs to work on his real-life sword attacks.
I Let Gwen Stacy Die: During his time with the Black Cats, protecting and comforting Sachi from her fear of dying helped to assuage some of his guilt over being a beater and solo player, but his half-heartedness came back to bite him hard in the end when his inability to admit his background and knowledge indirectly caused her to die from a trap.
I'm a Humanitarian: When he uses an illusion spell to apparently turn into a monster, he eats some of the enemy players, and then chomps on Leafa's fingers when he turns back to normal. He was just joking, though.
It happens again in episode 24, when Sugou impaled Kirito with his own sword, just after altering the pain absorber to make the experience even worse for him.
Implausible Fencing Powers: After two years trapped inside SAO, Kirito is possibly the best VR sword-fighter in existence. He goes into Gale Gun Online... and buys a light-sabre, which he uses to deflect bullets. He later uses this experience to control (uncontrollable) Sword Skills well enough to cut spells out of the air. You can practically taste the Oh Crap expressions of the first set of enemies he demonstrates that to.
Dark Repulser (One Handed Straight Sword - player-made by Lizbeth)
Excaliber (Retrieved as a Quest Item, with a handy assist from Shino)
Narrator: Throughout most of the light novels, he is the one narrating the story.
Nice Guy: Isn't reluctant to help those in need, even strangers on the road.
Nice Job Breaking It, Hero: Of the Poor Communication Kills variety. Before committing suicide, Keita pointed out to him that if he actually was upfront about his stats and didn't withhold information in fears of being outed as a Beta Player, their guild would have still been alive.
No Sell: Kirito vs. the (player-attacking) Orange Guild Titan's Hand. Half a dozen players, hacking away at Kirito as hard as they can. He has so much health that it'd take them about 5 minutes to kill him... except that he regenerates faster than they can hurt him... and he gets tired of being used for target practice and tells them "Go to prison or... get paralyzed and thrown in anyway."
Not So Different: Notes that he and Sugou are similar, as they were both defeated and then forced to assist Akihiko Kayaba - the difference being that Kirito never sought to become like Kayaba or Sugou.
This is less prevalent in the English dub, though, since Suguha calls him by his name, instead of "brother".
Ordinary High School Student: Yeah, Kirito is a rather skilled VR-MMORPG player (er, addict), and a SAO Beta Tester, but other than his mild family issues, there's not much unusual about his backstory. Or his present... until Kayaba traps everyone in SAO.
Our Hero Is Dead: Partway through volume 9, one of the Death Gun perpetrators who managed to escape comes back for revenge against Kirito, and succeeds in stabbing him with a deadly dose of succinylcholine. Although he manages to take his enemy down before succumbing to the effects of the poison, it was too late. Asuna calls for an ambulance and the heart monitor flatlines. The plot then shifts into the "Virtual Underworld". It is revealed in volume 10 that his body recovered from the dose but his brain was damaged so Seijuro Kikuoka pull some strings to get him to the Ocean Turtle and hook him up to Underworld so it can be repaired.
Signature Move: In SAO, it's his Dual Blades skill, though it's kept hidden for the most part.
Silent Scapegoat: In episode 2 of the anime adaption, he takes on the title of Beater in order to separate all the other Beta players who help others with Betas who take advantage of their knowledge at the expense of others (Beta+Cheater).
Spider-Sense: The Outside System Skill, Hypersense. Despite being a hypothetical hidden skill, Kirito notes that several times in SAO, he'd felt the presence of someone watching him and credits the skill for saving his life.
He had the fastest reaction speed of all players in SAO, which was why the system granted him his trademark dual-wielding ability.
In ALO, his reaction speed played an even bigger role as it determined one's ingame movement speed and attack damage. He was so fast that his speed completely overwhelmed one of the fastest players of the race with an affinity for speed, and was able to pummel players with high-level armor with the standard beginning equipment.
In GGO, his reaction speed is shown to be demonic enough for him to slice showers of bullets midair with his lightsaber as long as he can sense their trajectories. When he returns to ALO, he uses the same technique to easily block magic attacks which have notoriously small hitboxes, noting that magic attacks were far slower than bullets.
Survival Mantra: The quote at the top of his trope list, said at end of the first episode of the anime. And followed up by the aforementioned Skyward Scream.
Survivor Guilt: Feels haunted by the guilt of being the only surviving member of "Black Cats of the Full Moon".
Sword and Gun: Does this in GGO, due to his preference and the lightsaber being too expensive for him to get anything better than a pistol.
Ultimate Showdown of Ultimate Destiny: Meets Silver Crow/Haruyuki from Accel World in the side story Versus. Of course, as pure fanservice, he's back to his old Black Swordsman Kirito form as the two fight in an epic battle. It ends in a draw.
Unskilled, but Strong: In the Fairy Dance arc, because SAO and ALO are built on the same source code, his compatible stats from SAO are transferred over. For the duration of the arc, he uses the default starting skills and equipment of the Spriggan class. However, since his SAO stats are through the roof (and ALO stats being limited by there being no levels to grind), the effects of his basic spells are amped up beyond belief. A small smokescreen spell turns into a massive explosion of smoke, and a basic illusion casting spell outright transforms him into the boss creature he was trying to create a facsimile of, broken party-killing moveset and all. He later resets his stats so he can make a proper Spriggan build and have fun with it.
Unstoppable Rage: Go ahead, just try to harm anyone he cares about. Especially Asuna. I don't think there will be enough of you to fill a bucket once he's finished with you.
What You Are in the Dark: Sugou, the villain who is engaged to Asuna, who has kidnapped her, and tortured her and Kirito in cold blood, is finally held with a knife to his throat by Kirito in real life. With no one else around at so late an hour, Kirito could easily kill him and put him out of everyone's misery... But he doesn't. He spares Sugou and leaves him for the police.
Willfully Weak: Lisbeth and the rest of the girls speculate this is the case for Kirito.
Lisbeth:This is what I think. Probably, in a normal game, Kirito won't fight seriously anymore. On the other hand, Kirito only fights seriously when the game isn't a game anymore, when the virtual world becomes real... That's why it's better if situations which force him to fight seriously don't appear. From the beginning, he was the type to easily get wrapped into troublesome things.
Would Hit a Girl: He expresses that he does not like to fight females, but he could if he has to.
He threatened the female leader of the player-killing guild "Titan's Hand" to intimidate the guild.
He once dueled Asuna due to their disagreement on using an NPC village as bait for a floor boss and won.
He took out the female GGO player Musketeer X during BoB.
Zero Approval Gambit: Outs himself as the first "Beater"* a portmanteau of "beta tester" and "cheater" to lessen the prejudice against beta testers from the normal players. By doing this, he focuses the stigma exclusively on beta testers who selfishly keep foreknowledge of the game to themselves, protecting the other beta testers who do no such thing (such as his friend Argo).
Asuna Yuuki/Asuna (SAO, ALO); Titania the Queen of Fairies (ALO); Erika (ALO)
"I don't want to lock myself in a room at the Town of Beginnings and slowly rot away. I'd rather stay the way I am until the last moment. Even if a monster beats me and I die... I won't lose to this game nor this world, no matter what."
The main female protagonist. In SAO, she is the sub-leader of the frontline guild "Knights of Blood". Her speed and proficiency with a rapier is so advanced that she has earned the moniker of "The Flash".
The anime adaptation got hit pretty hard because of this. Since later volumes tell events from the Aincrad arc in a non-linear fashion, but the anime tells them in linear progression, Asuna's characterization flip-flops a bit. For example, in episode 11, Asuna shows that she is afraid of ghosts. However, previously in episodes 5 and 6 the story also involves the possibility of ghosts, and yet she doesn't even flinch. That's because while the events of episode 11 were originally told on volume 2 of the light novel series, the events of episodes 5 and 6 were told in volume 8.
Chef of Iron: She's an extremely skilled swordswoman, and has mastered her Cooking skill.
Clothing Damage: When Sugou starts to strip her with the intention of raping her.
Combat Medic: Her ALO build; while she plays as an Undine healer, she hasn't forgotten how to use her rapier. More than once she's switched from healing to taking down the level boss.
Curb-Stomp Battle: When the 21-30th floors of Aincrad were opened in ALO, Asuna, her friends and alongside 50 other players rushed right to the floor boss, where they watched in awe as Asuna single-handedly take out the boss, kicked it to the side, and rush onward to the 22nd floor. The reason was to purchase the small wooden house in the middle of the forest, the same house herself and Kirito briefly lived in, back in SAO.
Custom Uniform of Sexy: A rare case where it was customized by the other members of her guild. They guilt tripped her into wearing it, due to how much it cost.
Died in Your Arms Tonight: In SAO, she dies in Kirito's arms after taking a fatal blow for him in the final battle. She gets better.
Difficult, But Awesome: Her speed, both attack and movement. In VRMMORPGs, you can concentrate to speed up attacks significantly. However, if you do it even slightly incorrectly (which gets more and more likely the more you are trying to speed up the strike), you cancel the attack and get frozen for a split second. By the time Asuna first meets Kirito, she (as a rookie!) has faster attacks that even he does. Similar rules (though usually without a possible freeze penalty) apply to movement, and Asuna has one of the highest movement speeds of any SAO player.
Dude Magnet: She says she has received many confessions and proposals from guys.
He Is Not My Boyfriend: In the anime, when Lizbeth wishes her good luck in her relationship with Kirito. Averted in the novels, where once Liz has met Kirito, Asuna quietly confirms her interest in him instead.
Lonely at the Top: In SAO, as second-in-command of the Knights of Blood, she demanded iron-like discipline and steel-willed among all the members, and thus never smiled in front of them as an example. However, while the members followed her orders, she noted that it was out of fear, not respect. This is also the reason why Asuna never joined another guild in ALO, not even a small one between Kirito and her friends.
In GGO, her touch also reminds Kirito that he has a handgun, not just a lightsaber. Despite the fact that he's in a game, and she's in the real world. Of course, between what we've learned about Fluctlight, and the fact that Amuspheres (like Kirito was using) are less-powerful and don't block 100% of nerve signals, this probably isn't "Magic". (Unless Fluctlight counts as "Magic".) Still, you never know...
Meaningful Name: Yuuki means "Courage" and Asuna can be translated as "For Tomorrow."
Rapunzel Hair: It reaches her waist and it becomes even longer as Titania. In the former case, it could reflect her ojou status but the later is clearly Sugou's work. She's supposed to be Queen of the Fairies after all.
Samus Is a Girl: In Aria in the Starless Night Kirito originally mistakens her for a guy, until she speaks. Before hand, she utterly awed him in regards to the speed of her Linear skill. It's also entirely possible that most of the people at the first boss battle didn't realize she was a she until her cloak was discarded.
Seen It All: Her reaction to Kirito's Spell Blast? (A feat of incredible control and precision that everyone thought was impossible.) About three parts Seen It All (type 1) to one part "Hey, cool!"
Sleep Cute: Very much so. Even when she just woke up also.
Hopeless Suitor: Even if Asuna was out of the picture, poor Suguha wouldn't have a chance with Kirito anyway. While they are technically cousins, he probably wouldn't see her as anything other than his sister.
Katanas Are Just Better: Her preferred weapon. Justified as she practices kendo in real life, and is very good (national-level middle school quarterfinalist).
Kissing Cousins: She wants this with Kirito, though it's quite clear that it ain't happening.
Luminescent Blush: When she realized that she had fallen asleep in Kirito's bed, with cleavage visible, and that he had woken up before her and noticed.
Loves My Alter Ego: Falls in love with Kirito, unaware that he is actually Kazuto. Since she had fallen in love with Kazuto, only to give up on winning his affections, she takes this rather badly.
Magic Knight: Skilled with using both attack magic and her katana.
Not Blood Siblings: She falls in love with her adopted brother and cousin who was raised with her since they were infants, only to get her heartbroken. Then gets it inadvertently broken again by him in ALO.
Spell My Name with an S: Official translations give her avatar's name as "Leafa". However, typos in the anime occasionally write it out as "Leefa" and fan translations of the novels used "Lyfa". A literal reading of the kana used in the novels would give you "Rifa".
Kirito actually dreads the day that she manages to obtain the ALO legendary bow, Shekhinah. The reason is that Sinon estimates that with that bow, she should be able to snipe from 200 meters away and can turn anything into a pin-cushion before they can possibly get within melee/spell range.
Cat Girl: Her appearance and mannerisms are often compared to those of a cat. Fittingly, she rolls a Cait-Sith in ALO.
Cold Sniper: At first, until warming up a little to Kirito.
Dark and Troubled Past: As an 11-year old, she killed a gun-wielding robber who was going to shoot her mother and/or a teller. She grabbed the gun, they struggled, and she fired. The experience so traumatized her, she developed PTSD and a strong phobia towards any gun, and not only her schoolmates but her mother shunned her as a murderer. She started playing GGO to try and get over her phobia of guns, but it's only partially successful.
Glass Cannon: Her character build in GGO focuses on STR and AGI, at the expense of VIT.
He Is Not My Boyfriend: She invokes this after Kirito (wisely) asks her to clear up any potential misunderstandings. Whether or not she actually does develop a romantic interest in him is left ambiguous, but there is some back-and-forth teasing between them. She also Trolls him (in a glorious fashion) by asking him to "always think of me" when using Excalibur... in front of all his other love interests. Only the twitching of her Cait-Sith tail gives away her laughter.
Heroic BSOD: Suffers a massive one when she realizes that the pistol that Death Gun uses to kill his targets is the very same pistol she used to kill the bank robber years ago.
Hero of Another Story: Literally. Although she created an ALO character to play with Kirito and her new friends, she still mainly plays GGO, where she is one of the top players and goes on her own adventures in that game world.
Improbable Aiming Skills: Manages to hit a falling sword at 200m with a bow whose maximum effective range was 100m, while falling herself, while surrounded by falling ice shards, while using a spell that distorts the arc of her arrow.
ALO players consider Shino's normal attacks to be this; she plays as a Cait Sith specced for long range vision, and regularly takes down enemies 100 meters away by arching her arrows. Shino doesn't consider it anything special, since she came from GGO and regularly engages from beyond 1000 meters with her Hecate II.
It still isn't enough for her. She's hoping to obtain the legendary bow Shekhinah because she estimates with that bow she should be able to snipe from 200 meters away.
Instant Expert: In ALO, it took her all of one day to fully master the bow.
There Are No Therapists: Averted; She's been in therapy ever since the incident where she killed a gun-wielding robber in self-defense, but it didn't really do her any good as they were all Japanese therapists who fully embraced their culturally-enforced disgust for guns - and those who use them. What straightens her out after years of this is meeting the teller the gunman threatened; the woman was pregnant at the time, and though she can't really get over her horror at witnessing a shooting, let alone meeting the shooter, she feels indebted to Shino for saving her baby - who is now four years old and gives her a cute picture of herself, her mother and her father stating, “Shino onee-san, thank you for saving mama and Mizue.”
Trick Arrow: Arrows with special magical properties exist in ALO.
Averted in GGO, where she's more of a high-ranked Glass Cannon.
Worthy Opponent: Sees Kirito as one, and wants to face against him in a future Bullet of Bullets tournament so they can finally have a proper battle. Though she'll never admit it, she greatly admires his skill, and even secretly bought her own lightsaber to practice deflecting bullets, with limited success.
The second main female protagonist of Mother's Rosario, volume 7. An energetic, cheerful girl who is the leader of the ALO guild "Sleeping Knights". 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.
Always Someone Better: Duels with ace hero Kirito twice and wins both rounds. It is debatable who is actually more skilled, as Kirito never fights her with his signature two bladed style, but her reaction speed and VRMMORPG experience are significantly better than his. Kirito stated that if she had entered SAO, the system would have awarded her the dual blades ability rather than him due to her superior reflexes.
Angsty Surviving Twin: Subverted for the most part, but shows hints of this when she gets strongly attached to Asuna due to her resemblance to her twin sister.
Badass Adorable: She's one of the kindest and most cheerful person in ALO. She's also probably the only person who can beat Kirito in a fair duel.
Lightning Bruiser: Remember how most opponents can't even react to Kirito dashing towards them before its too late? Lets just that Kirito can't even react to her and leave it at that.
The Pollyanna: Despite her entire family being killed off one by one by AIDS until only she was left to endure the disease and social stigma alone, she remains cheerful and as energetic as an Ill Girl could possibly be.
The leader of the SAO guild "Knights of Blood", of which Asuna is a member. Known as "The Holy Sword", Heathcliff is a legendary player whose HP has never dropped below 50%. He possesses the Unique Skill "Holy Sword", which lets him use his tower shield as an offensive weapon.
Crutch Character: Heathcliff is something of a meta-example of this trope; he's the ultimate tank who fights on the front lines with his men, and created the strongest guild specifically to collect the game's biggest badasses. He also intended to betray the players on the 95th floor to set himself up as the Final Boss.
Deus ex Machina: Serves as this in ALO, as it is through the Heathcliff login that Kirito assumes superuser control of the system.
Distinctive Appearance: Unlike other members of the "Knights of Blood", his uniform is primarily red with white trimmings.
Jerkass: He treats Asuna like a trophy despite being her subordinate and treats Kirito like trash despite being ten levels lower than him. Kuradeel is a jerkass even in death. With his last words, he accuses Kirito of "murdering" him, even though he tried to kill Kirito and Asuna (and did kill Godfrey), forcing them to fight back in self-defense.
Karmic Death: Gets punched into oblivion by Kirito. Au revoir, jackass!
Stalker with a Crush: Towards Asuna. He lurks around her house at morning (and implied at night) because 'it's his job'.
The first friend that Kirito made in SAO, and also the first person he partied with. When they are trapped within SAO, Klein chooses to remain and help his real-world friends instead of going with Kirito. He ends up becoming the leader of the "Fuurinkazan", a powerful guild notable for having a mortality rate of zero.
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.
Dogged Nice Guy: A non-romantic example to Kirito. He keeps trying to get Kirito to join his guild 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.
I Will Wait for You: A non-romantic example. He always holds a open hand to Kirito to join him and when Kirito as at his lowest point, Klein still was friendly to him and wanted to help him, even when it seemed Kirito might be willing to fight him.
Nice Guy: Very much so. His first thought when Kayaba announced SAO's true state was to find his friends and take care of them, and he invited Kirito to join them.
Overshadowed by Awesome: Klein is one of the top players in SAO, and has led his guild with no casualties throughout the time they were trapped in Aincrad, even when participating on the frontlines: not even Knights of Blood, the strongest guild, can boast that. He'd be the main character in any other setting, but his friends are The Black Swordsman Kirito and Asuna the Flash, so yeah. He gets a chance to shine in the Volume 8 story Caliber, where he proves to have some damn big brass ones.
Spider-Sense: Like Kirito, he possesses the hypothetical skill, Hypersense.
Took a Level in Badass: Seriously. 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 apparently had nobody die in it. Not even the Knights of the Blood can boast that!
Facial Markings: She has whisker markings, which she applies with make-up. The information on why she has them has a high price tag of 100,000 col. She originally got them as scars during the beta test, when she tried and failed the quest to unlock the "Martial Arts" Extra Skill. When her character was transferred to the main game and the scars vanished, she liked the markings enough to apply them using make-up.
Meaningful Name: Argo means "swift" in Greek and her character build is focused on agility.
Only in It for the Money: She is incredibly sly and greedy, and will sell any piece of information for the right price, including the identities of her clients and the information they bought from her. She observes that as soon as someone buys information from her, she gets a new piece of information (X bought Y from her) to sell. Though she draws the line at selling the identities of other beta testers. She is also the author of a free strategy guide for beginner players, detailing the hazards and best hunting spots of each floor. Kirito observes that this is probably her way of "atoning" as a beta tester.
Genius Bruiser: Big and intelligent in combat. Don't think this salesman is for nothing, he's a tough one.
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.
"The Reason You Suck" Speech: Gives a minor one to Kibaou in Episode 2 when he 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.
A "knight" who organised and led the raid against the boss of the first floor. He is actually another beta tester, and exploits the raid group in order to ensure that he lands the last hit on the boss, which would maximise his chance of obtaining the unique drop. Recognising Kirito as another beta tester, he also takes steps to actively hinder his rival by manipulating Kibaou and assigning backrow duty to Kirito's party.
Adaptation Distillation: In the light novel, he's practically the villain of the piece. The novel contains an additional subplot about a mysterious benefactor trying to buy Kirito's powerful sword, later revealed to be Kibaou (acting as Diabel's middleman) as part of a scheme to weaken Kirito and further lower his chances of getting the final hit. The novel also contains more implications that Diabel is a Beater, making note of the obscene amount of Col he can throw around (for the first floor) and his possession of rare items such as his blue hair dye.
Didn't See That Coming: The boss on the first floor has a different weapon and fighting style when it Turns Red, which was much different from what was stated in the manual. He gets killed as a result.
A warrior who participated in the 1st floor boss raid who has a dislike for beta testers.
Corrupt Corporate Executive: He becomes one later on as part of The Army. His group of followers are really nothing more than a bunch of extortionists. Later tried to get rid of Thinker, rather than having to answer for his screw up that got some of his fellow guild members killed.
Hate Sink: The point of Kibaou's character is to show that even in a life-or-death situation, people can still be jerks.
Incoming Ham: When he first makes his appearance, Kibaou loudly demands everyone's attention before flamboyantly hopping his way down to Diabel's stage.
Irony: Greatly respects Diabel, not knowing that he is actually a beta tester and is just using the raid group to get a rare floor boss item via exploiting the last hit system and screwing over Kirito. He respected the very type of player that he hated.
Jerkass: He's easily the biggest one in the Aincrad arc, and a contender for the biggest one in the show.
The Load: Complains much and contributes little. By the end of the second episode he incites a witch-hunt against beta-testers that dissembles the coalition Diabel put to together.
Spiky Hair: Sports random, protruding spikes from his hair that resembles a mace.
Meaningful Name: Apparently 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 birth date 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 for Silicon. Kirito figured all that out from the simple hint that "My name comes after Alumi, and before Rin". Silica was shocked.
Red Baron: In SAO, she is known as "Dragon Master".
Rescue Romance: This sort of happens, which prompts her attraction to Kirito; he saves her after Pina performs a Heroic Sacrifice, helps her get the resurrection item, and protects her from Titan's Head.
Cannot Spit It Out: Never manages to directly tell Kirito about her feelings. Unlike most dense harem protagonists however, he catches on the gist of it from her embarrassed stuttering and turns extremely embarrassed himself upon realizing it.
Clingy Jealous Girl: Despite supporting their relationship, she gets angry when she sees Kirito and Asuna getting lovey-dovey.
Cool Big Sis: Seems to be a bit of one towards Silica once they get out of the game.
Drop the Hammer: Happens on a daily basis, as she's constantly beating metal into weapons and armor.
Glass Cannon: Originally, her weapons focused on sharpness and quickness, while largely ignoring durability. After Kirito effortlessly destroyed her best sword, she realised that in a desperate situation, what could ultimately save the lives of her clients is the weapon's durability.
A member of the Ministry of Internal Affairs, who's responsible for monitoring situations in the virtual world, Kikuoka was present when Kirito returned to the real world, and the person who asks him to investigate the Phantom Bullet case. He maintains an ALO account, though it's mostly used as an alternate method to contact Kirito and Asuna.
M.I.B.: A more overt example, working for the Ministry of Internal Affairs, or so it seems. Kikuoka appears to actually belong to the JSDF, and Kirito suspects the JSDF is monitoring the progress of VRMMOs as a substitute to real world training.
Necessary Evil: Wants to figure out a way to create intelligent AIs that can be used to replace humans in real wars, and is more than willing to cross ethical boundaries to do is, including essentially making virtual clones of real infants and playing god with a virtual civilization. On the other hand, he does so in hopes of preventing humans from getting killed in wars, keeping up with the advancement in technology, making Japan more independent from the American military, and truly does care about Kirito and his friends. He even agrees with Asuna that like Yui, AIs can become "alive" like a human, but would ultimately choose the life of a single human over hundreds of thousands of intelligent AIs.
An administrator for "MMO Today" and the leader of the Aincrad Liberation Front, the largest guild in Aincrad. Thinker's leadership and influence in the guild has slowly been eroded thanks to Kibaou his 2nd-in-command, and he's eventually trapped unarmed in a dungeon, prompting Yulier to request Kirito and Asuna to help rescue him.
Taking You with Me: Knows a darkness magic that kills himself while destroying nearby enemies.
Kyouji Shinkawa/Spiegel (GGO)
Shino's best friend, and the one who introduced her to Gun Gale Online.
Crippling Overspecialisation: "Spiegel" is an AGI-heavy build, relying entirely on evasion and speed of attack. When the GGO metagame evolved to favour balanced STR/VIT builds, Kyouji was left with a severely underpowered character that lacked the STR to equip anything but the lightest guns.
Education Mama: His parents are high-ranking doctors and put a lot of pressure on him to succeed.
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.
Back from Deletion: Kirito manages to save her information before she's entirely deleted from the system, and successfully brings her back in ALO.
Badass Adorable: Cute & 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) & utterly erase you from existence. Even if you are a nigh-invulnerable boss monster. In short; Do not taunt the happy fun admin.
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.
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.
Ambition Is Evil: He tells Kirito of his dream about creating a floating castle as the basis for creating Sword Art Online.
Badass: He created every Sword Arts in Sword Art Online, including Kirito's Dual Blades techniques.
Badass Bookworm: He also programmed all of SAO, and designed the hardware. By himself. Even after his death he created a program that revived the VRMMORPG genre in the aftermath of the Fairy Dance arc.
Big Damn Heroes: At the end of the Fairy Dance arc, his spirit seemingly comes back from the dead to give Kirito his Administrator privileges so he can defeat Sugou.
Evil Counterpart: To Kirito. At one point, Kirito even hijacks his admin credentials to save Yui.
Even Evil Has Standards: He may have caused the deaths of 4000+ players just to bring his imagination to life, he keeps his own rules even if it meant losing everything. By these standards he holds Nobuyuki Sugou in contempt and helps out Kirito in taking him down.
Fair Play Villain: Zigzagged, he keeps his own rules, even when it costs him his world and his life. However, he did make himself an Immortal object as Heathcliff
GMPC: Considered to be the strongest player in SAO. The Leader of the most powerful guild. One of the only two known people with a Unique Skill. Have never been seen being brought down to below 50% HP. Respected by all. Granted he expected himself to be revealed at around the 95th floor and deliberately did this to bring forth the greatest despair to the players. On the other hand, he tends to not do much and fights passively, letting the rest of the players do their own thing and to figure out what to do on their own. It was the combination of all the above that led Kirito to suspect this trope and thus his true identity.
The GM Is A Cheating Bastard: To protect his guise as Heathcliff in his duel with Kirito, he accelerated faster than the normal players in SAO to block damage. He also has the "Immortal Object" ability normally granted to environmental objects to protect his life if his HP goes below 50%.
In the second duel Kirito noted that Kayaba did not, in fact, need the additional assistance to strike that fast.
A God Am I: While he never claims to be anything more than a programmer, Kirito notes that his behavior is godlike - looking upon the players not with empathy, but with mercy and pity. This is what allows Kirito to identify him as Heathcliff.
Graceful Loser: When defeated three-quarters of the way through the planned SAO, Kayaba congratulates Kirito and Asuna, and lets them both live and return to the real world, even though they had both "died" in the virtual world.
Karma Houdini: He dies on his own terms. Also, he is Easily Forgiven by Kirito despite being responsible for the deaths of over 3000 people.
Psychopathic Man Child: His ultimate goal is essentially to bring the world of his imagination to life and have it be as real as possible. He also posses a certain sense of fair play. This would make him a Type C with bits of B and E mixed in.
The Stoic: Even when Kirito overcomes death to attack him one last time, his expression barely changes.
The director of RECTO's research institute. He high-jacked the minds of 300 of the SAO victims (including his then-fiance Asuna) and traps them in his own game ALFheim Online to experiment on them. The antagonist of volumes 3-4.
Corrupt Corporate Executive: He is the director of RECTO's research institute and the one responsible for keeping 300 Nerve Gear victims, including Asuna, prisoner even after SAO had ended. He did this by transferring them all into ALO for experiments on human subjugation via fulldive technology. He also attempts to take over RCT Progress Inc. by marrying Asuna while she is unconscious.
Evil Cannot Comprehend Good: He mocks Asuna by telling her he met Kirito in the real world, and how weak he looked. He is completely unaware that letting her know her lover was alive was exactly what she needed to keep going.
Was also convinced that Kirito would be too scared to even put on his Nerve Gear, let alone try to save Asuna, boy was he wrong.
Eye Scream: Suffered this by Kirito at the final part of his Curb-Stomp Battle by letting his sword fall into him and because of the pain reception he brought up during that fight it transfers into the real world with painful irritation and bad vision from that right eye.
Knife Nut: He tried to kill Kazuto in the real world with a combat knife. Thankfully gets his ass handed to him & handed to the police by his supposed-victim, thanks to the skills he learned in game.
Last Villain Stand: By the time he decides to pull a knife on Kirito in the real world, Sugou has suffered a complete Villainous Breakdown and has pretty much lost everything, save one last, desperate chance to get back at our hero.
Lecherous Licking: When he is sexually attacking Asuna in Alfheim Online, she starts to cry in humiliation and he extatically licks her tears.
Siblings in Crime: The original two members of the team. The eldest was a former SAO player who was part of the red guild "Laughing Coffin"; he was the one who collected info on where their targets lived, was the one who injected Zekushiido and Usujio Tarako with Succinycholine in the real world, and is the one who shot the avatars of Pale Rider and Garret in GGO during BoB. The youngest was the one who shot the avatars of Zekushiido and Usujio Tarako in GGO, and during BoB he was meant to break into Shino's home and inject her with a dose of Succinylcholine with a needleless syringe. Both were children of a doctor and had access to the funds and equipment needed to pull it off.
A guild in SAO who revelled in killing other players. Because of this, they became known as a "red guild" and were eventually wiped out by the frontliner guilds.
Laser-Guided Karma: Though not all of them manages to get away unpunished. After the attack on Kirito & Asuna by Kuradeel, the Knights Of Blood put the floor-clearing on hold & with a lot of other like-minded players, initiated a purge to track down all members of the guild & bring them to justice. Most of the psychos were killed however, when they tried to fight back. Some of them, including Xa Xa & Johnny Black manages to escape though & remains at large. At least, until the Death Gun incident.
Murder, Inc.: Sometimes, some players will hire their services to kill a target as a means to avoid having their Karma Meter changed to orange or red.
Villain Forgot to Level Grind: Averted. After his capture and imprisonment in SAO, he did nothing but train with his rapier skills, to the point where like Kirito, he can replicate SAO moves via muscle memory and can actually beat Kirito in a sword fight(though it should be noted that Kirito couldn't fight all out as his lightsaber had no weight, and he's too used to heavy swords.).
Johnny Black (SAO)
One of the top members of the Laughing Coffin, and a survivor of SAO.
Axe Crazy: Johnny's dialogue does not hint at a sane mind.
Unrequited Love Lasts Forever: Thinks she'll never get married, because she's in love with someone who can never return that love. Three guesses whothatis. Still, she has descendents in the epilogue, so it looks like she gets over it.
Eugeo's valet during his time in the Master Swordsman Academy.
