Characters from the Accel World series are sorted according to their main allegiance within the light novels, anime, manga, and video games.
- Breaking the Fellowship: The failed raid on the Imperial Palace, which resulted in Ardor Maiden, Aqua Current and Graphite Edge being trapped in precarious positions on the Unlimited Neural Field, in which the Four Gods will kill them if they try to log back in. It took a great deal of effort to rescue Ardor Maiden from this situation
- Elemental Powers: The Elements of the old group represented the classical four elements. Sky Raker represented air, Ardor Maiden represented fire, Aqua Current represented water, and Graphite Edge represented earth.
- Elite Four: The Elements, the four lieutenants of the first incarnation of Nega Nebulus. Shortly after Black Lotus's declaration of war on the other kings, they attempted a raid on a group of Beef Gate bosses themed after The Four Gods. Instead, three of them became trapped in a Cycle of Hurting inside the bosses' spawn zones, and the Legion fell apart soon afterwards.
- Putting the Band Back Together: So far, Sky Raker and Ardor Maiden have rejoined Kuroyukihime, and Haruyuki hopes the other Elements will, too. as of vol 14, Aqua Current has rejoined as well.
- True Companions: They're considered a very close-knit group, especially the new Nega Nebulus, which Haru thinks of as a family of sorts.
Haruyuki "Haru" Arita/Silver Crow
The main character, a short, overweight boy with severe self-esteem issues mainly caused by not only his appearance, but also being viewed as an outsider at Umesato Junior High School. An encounter with Kuroyukihime, however, changed his life, as he slowly discovers his power to stand up for himself.
- Accidental Pervert: He repeatedly ends up in situations where he accidentally gropes or sees undressed one of the girls. This actually gets Played for Drama when Seiji uses a visual mask to lead him to the girls' shower room while Chiyuri is taking a shower as part of a trap to blackmail Haruyuki - Chiyu realizes that Haru was tricked, but knows that he could be expelled if word got out.
- Adaptational Ugliness: A downplayed example. While Haru isn't physically attractive in the light novels, the anime exaggerates Haru's character design to match his self-image, making him much more cartoonish. In the books, he's only a few centimetres shorter than Takumu, who in turn is taller than Chiyu.
- Adorkable: He's insecure, socially awkward and a very cute and endearing little guy.
- Affectionate Nickname: Takumu and Chiyuri call him Haru.
- All of the Other Reindeer: He is viewed as an outsider from his school because of his appearance.
- All Your Powers Combined: After becoming the sixth Chrome Disaster, he synchronizes so strongly with the Armor that he can use the abilities of its past hosts. However, he isn't familiar with these abilities' strengths and weaknesses, which comes back to bite him.
- Animal Motifs:
- A literal flying pig.
- As well as a crow given the name of his avatar is Silver Crow.
- Apologises a Lot: He has the habit to apologize for every single thing, even if it's not his fault.
- Attack Reflector: Develops the "Optical Conduction" ability in volume 12 as an extension of silver's use in mirrors, growing crystals on his arms which can reflect or Catch and Return light-based attacks.
- Badass Adorable: Insecurities aside, he's also a sweet, caring boy. Just don't dare hurt his friends.
- Beady-Eyed Loser: He's a short, fat boy with very beady eyes and when the series starts he's a loser who is a target of Araya and his gang's bullying.
- Big Fun: Once he starts to gain more self-confidence, Haruyuki becomes a gentle, friendly and fun fat little guy, but hardly boisterous.
- Book Dumb: Haru's grades aren't especially good, but he's really quite intelligent. It's indicated that he doesn't have the energy or focus for long study sessions, note and he fears that he'll never be able to get into the same high school as Kuroyukihime.
- Broken Angel: In book 3 after Noumi steals everything from him, even his wings.
- Call of the Wild Blue Yonder: The reason why his avatar manifested wings. Initially Haru just wants to fly away from his problems, but as he grows in confidence he shifts towards a straighter example of this trope, admiring birds and loving the sky for its own sake. This culminates in the birth of his second-order Incarnate technique "Light Speed", which lets him activate Crow's wings through sheer force of will.
- The Champion: For Kuroyukihime. Haruyuki makes his goal to help her achieve level 10 so he can protect her and repay her for changing his life by giving him the Brain Burst. It's actually part of Haru's Character Development that he's trying to make himself worthy of being her knight.
- Chekhov's Skill: After a failed attempt to use Crow's Charged Attack "Headbutt" at the very start of his career, Haru declares it Awesome, but Impractical and falls back to simple punches and kicks from then on. As a result no one outside Nega Nebulus knows that Crow even has this attack, which allows Haru to gain the upper hand against Wolfram Cerberus (a linker who studied his fighting style) when he tries to defeat Crow by crushing him in a bear hug.
- Childhood Friends: He has been friends with Takumu and Chiyuri since they were living in an apartment complex as children.
- Classical Anti-Hero: At the beginning of the story, Haruyuki is a pathetic loser with no self-esteem and plagued with self-doubt. He gets much better thanks to Character Development and eventually evolves into a proper hero.
- Contrasting Sequel Main Character: If you consider Accel World the Spiritual Successor to Sword Art Online, Haruyuki is quite a contrast to Kirito. Kirito was a lean, confident, loner badass whereas Haruyuki is a fat, wimpy kid who tends to rely on his friends. Word of God is that the big difference between them is that Kirito was strong on the outside, but weak on the inside. Haruyuki is weak on the outside, but strong on the inside. In a more meta-sense, Kirito might exemplify the gamer's ideal image whereas Haruyuki more-or-less represents the gamer's reality. Despite this, the two were pretty evenly matched when they fought each other in a non-canon bonus chapter.
- Confusion Fu: After people start to get used to Crow's Flight ability and he can no longer rely on Death from Above Diving Kicks to carry him to victory, he develops the "Aerial Combo" fighting style - a furious barrage of close-range attacks which use his flight ability in short bursts in order to micro-dodge and attack from unpredictable angles.
- Counter Attack: In volume 6 Kuroyukihime teaches him the basics of Guard Reversal, aka the "way of the flexible" - a martial arts technique for catching the force of opponents' attacks and redirecting them.
- Cyber Cyclops: Silver Crow. Though it's actually a visor covering a proper face.
- Declaration of Protection: He made a vow to support and protect Kuroyukihime as her "pawn" in the Brain Burst game.
- Determinator: You'd think losing a hand & having your body filled full of holes would stop anyone. Not this guy though. According to Chiyu, this has been one of his defining characteristics since early childhood; he just didn't use it for anything besides mastering games until now.
- Discard and Draw: In the Dusk Taker arc, Silver Crow lost his wings to Dusk Taker, caught by his surprise attack. He then is taught how to use a powerful ability called Incarnate System by Kurasaki Fuuko (Sky Raker), and is given her Enhanced Armament, Gale Thruster (a jet-pack). He gives Gale Thruster back to her after defeating Dusk Taker, but he keeps the ability he learned.
- Distracted by the Sexy: In the manga chapter, he doesn't quite perform up to his usual level in the first set because he's distracted by the hem of Kuroyukihime's skirt. He doesn't dare admit this, though.
- Diving Kick: Becomes Crow's Signature Move for a while after he first unlocks his Flight ability.
- Don't You Dare Pity Me!: His primary motivation for Taking a Level in Badass is so his friends Chiyu and Taku don't have to feel sorry for him. Unfortunately, this is also part of the reason why he distanced himself from his friends around the start of middle school.
- Dragged by the Collar: By Blood Leopard from the cafe straight to the Akihabara.
- Dreams of Flying: The "calibration dream" Haru has after installing Brain Burst features a flying bird made out of light, Foreshadowing Silver Crow's abilities.
- Elemental RockPaperScissors: Silver Crow gains the elemental properties of the metal silver, rendering it resistant to piercing, slashing, fire, ice, and poison attacks; but vulnerable to crushing attacks and electricity.
- Establishing Character Moment: When he's introduced, Haru receives a message from Araya demanding that the former buy him food or he will hurt him. Depressed about school, as usual, Haru escapes into the bathroom during lunch and plays a squash game, in which he has the high score. All this shows that Haru's a victim of bullying with terribly low self-esteem, and an impressive gamer.
- Fatal Flaw: His lack of self-esteem causes a variety of problems for him, often holding him back in battle and occasionally causing tension with his friends.
- Fighter, Mage, Thief: Silver Crow is the Thief to Cyan Pile's Fighter and Lime Bell's Mage.
- Flight: His avatar's special ability in the Accelerated World, and apparently the first one to be able to do so.
- Fragile Speedster: Silver Crow's general fighting style, until he grows wings, which turned him into a Glass Cannon. Accelerated World's hits operate on real world's principles (adding speed to your punches increases power) and he is really fast, to the point of being able to break the sound barrier. The "fragile" part comes from how his defenses are quite weak for a metal type, and he generally survives by avoiding damage.
- G.I.F.T.: Notable by its absence - he's one of the few people who acts exactly the same in Brain Burst as he does in real life. Word of God says this honesty is the reason for his Chick Magnet status.
- Giver of Lame Names: After coming up with a technique that creates cutting energy around his forearm to extend his reach, he decides to call it... Laser Sword. This is immediately mocked.
- Glass Cannon: After he grows wings.
- Godlike Gamer: Played with. While at first he seemed like your run-of-the-mill newb with Crippling Overspecialization that made him a Fragile Speedster, but then he's revealed to have natural talent and learns how to activate his wings (implied to be an Incarnate Skill which is very difficult to master), making him one of the few Burst Linkers who can fly and as a result one of the most dangerous Burst Linkers.
- Good Old Fisticuffs: Silver Crow relies on punching his opponents rather than using blades.
- Grew a Spine: As part of his Character Development, Haruyuki starts to gain self-confidence and finds the courage to stand up for himself.
- Guilt Complex: He has very little self confidence, and tends to blame himself when bad things happen. His friends have to reassure him that it's not his fault.
- The Hero: Part of his character development is becoming of one these proper; both in helping others like Kuroyukihime and overcoming obstacles in his path.
- Heroic Self-Deprecation: Even as he's making a name for himself in Brain Burst, Haruyuki thinks nothing great about himself and he'd still shy away from all the praise.
- I Can't Believe a Guy Like You Would Notice Me: The main reason why he can't reciprocate Kuroyukihime's feelings is that he can't believe such a beautiful, popular girl like her would actually give him a chance.
- Innocently Insensitive: Since he believes that a girl like Kuroyukihime is out of his league, he tends to unintentionally refuse her affection and make her feel insecure about their relationship.
- Insecure Love Interest: Despite his feelings being blatantly reciprocated, Haruyuki still thinks a girl like Kuroyukihime is out of his league and she deserves someone better than him.
- Invisible Parents: His parents divorced when he was about 8, and he hasn't seen his father since. While his mother has sole custody of him, she spends most of her time at work, apart from a few briefly mentioned parts in which she hands him his money in the light novels. She has about 30 seconds worth of screen time in the entire anime.
- Jumped at the Call: He considered installing Brain Burst for about three seconds. Kuroyukihime had a speech all ready to convince him but it was unnecessary. Even she's surprised at how eager he is.
- Lady and Knight: He's striving to be the knight of his legion master Kuroyukihime.
- Leitmotif: "Silver Wing" in the anime. While Crow is using Gale Thruster it's replaced by a remix titled "Iron Will".
- Lethal Joke Character: Silver Crow. Above-average speed but terrible stats everywhere else, and its supposed Finishing Moves are just normal punches, kicks and headbutts. Then Haru figures out how to activate Crow's wings, giving him Super Speed Flight that turns even regular punches into killing blows. Then he gains access to a proper Finishing Move from another source, which can be used while flying.
- Light 'em Up:
- In his battle with Wolfram Cerberus it's revealed that half of the damage dealt by his "Headbutt" Special Attack is light-based, making it useful against enemies with strong physical defences.
- His Incarnate abilities like Laser Sword and Light Speed are based around the image of beams of light. In volume 9 he uses Incarnation simply to illuminate his surroundings and flush Black Vise out of hiding.
- Loser Protagonist: He starts out as this, being a short overweight boy with zero self-confidence who gets bullied at school and pretty much has no friends. He gets much better through Character Development.
- Lovable Nerd: He's short, fat, socially awkward, and gets beaten up by bullies regularly. Once he gains some self-esteem, however, he quickly reveals himself as a Determinator.
- Mistaken for Gay: He and Takumu share a rather Ho Yay moment in Episode 21 and the girls around them seem to be misinterpreting the situation.
- My God, What Have I Done?:
- After bluntly saying that he believes that Kuroyukihime is only hanging out with him because she hates herself, angering her to the point where she calls him an "idiot" rather than a "fool," slaps him and breaks down in tears, he realizes how uncharacteristic of her this is.
- He also has this reaction after realizing that his boasting that Taku could never defeat him was a serious blow to Taku's pride as a Burst Linker.
- Naïve Newcomer: He does some dumb things due to his inexperience. He once leveled up his character without earning more points first, which since it made him lose a lot of his points it put him in danger of losing Brain Burst for good if he lost them all.
- Nice Guy: He's kind, selfless and supportive of his friends.
- Non-Standard Character Design: He looks very different compared to the other character designs, having a very short, doughy, and round character design.
- Not Distracted by the Sexy: Downplayed. When Scarlet Rain attempts to infiltrate Nega Nebulus by pretending to be his second cousin and acting deceptively cute, it doesn't take him too long to check if she is really his second cousin.
- Oblivious to Love: He takes it to a new level by finding signs that Kuroyukihime does like him and refusing point blank to even consider it. This is justified because of his low self esteem.
- Ordinary Middle School Student: He's just a normal and unlucky middle school student until Kuroyukihime introduces him to the Accelerated World.
- Parental Issues: Implied in the OVAs, and hinted at more strongly in the eighth volume: Haru believes his parents divorced because of him.
- Parental Neglect: It's indicated that his mother doesn't care much about him, and his father cares even less. That said, she does pay his allowance, not bother him about his grades and allows his friends to stay over, so Haru doesn't complain lest he risk the status quo.
- Personality Powers: Gained his flight ability from his desire to escape from bullies. After some introspection, he decides that his wings ultimately exist to let him fly to somewhere - the gift Brain Burst truly gave him was the will to reach out and keep moving forward.
- Power Loss Makes You Strong: He has his Flight ability stolen by Dusk Taker. Before he regained them, it allowed him to notice that the value of his Duel Avatar lies not in said ability, but in himself, gaining confidence (the lack of which was the main cause for him not being able to use Silver Crow to his full potential) in the process.
- Running Gag: underplayed. Being "cracked in the real" (having your real life identity exposed to another Burst Linker) is considered one of the most catastrophic things that can happen to you, just short of losing Brain Burst. Haru has done this by sheer accident several times. This culminates at the school festival in vol 13; he introduces Niko and Pard to Rin outside the gates, realizing too late that they will all automatically assume that 'my friends from gaming' is code for 'Burst Linker'; which he then compounds by introducing them to his entire Legion. Granted, Pard is Current's Child, and Ash is Sky Raker's, but he's cracked the Prominence Leadership and the newest members of his own Legion to a member of Green Grande. Luckily, it all works out due to everyone being chill about it, and leading to a temporary alliance when Rin falls ill from the ISS kit. Utai even thanks Haru in a quiet moment; she's looking forward to having Niko as a friend, given that as a partial red type she's sure they'll get along, and she'd like to have a Burst Linker friend her own IRL age.
- Sempai Kouhai: He constantly refers to Kuroyukihime this way, and abused by Noumi through Terms of Endangerment.
- Sensitive Guy and Manly Man: The Sensitive Guy to Takumu's Manly Man.
- Single-Target Sexuality: despite his I Can't Believe a Guy Like You Would Notice Me mindset, he's utterly devoted to Kuroyukihime romantically. It's stated in more than one book that she "is the person Haruyuki loved and respected more than any other".
- Square Race, Round Class: Haru is skilled at First Person Shooters, but Silver Crow is focused entirely on melee and controls more like a character out of a Fighting Game. He comments that he's a little jealous of "Perfect Match" players whose avatars let them apply their existing skills, and used to wish he received a Red avatar instead.
- Stock Light-Novel Hero: Haruyuki partly fits this trope. He was once an Ordinary High-School Student, albeit a very unattractive one with a Non-Standard Character Design, who finds his life changed forever when he gets introduced to Brain Burst, an augmented reality game. As a Burst Linker, Haruyuki gains Powered Armor and fights other Burst Linkers. While he's fairly pathetic at first, he soon discovers he's one of the only Burst Linkers to have a Duel Avatar with wings, giving him the ability to fly and a huge advantage over everyone else. As the series progresses, he also acquires an Unwanted Harem of girls fawning for his attention.
- Super-Powered Evil Side: In the latter part of Dusk Taker arc, Noumi's brutal beatdown on Cyan Pile makes Haru so supremely pissed that it temporarily awakens the piece of Chrome Disaster hiding on Silver Crow's back. The result is a crimson Battle Aura, similarly-colored incarnation attacks and a major case of flipping the hell out. As lucky as Noumi is, however, the duel timed out before anyone could gain the upper hand.
- This later becomes a standard part of his arsenal.
- Tiny Guy, Huge Girl: Tiny Guy to Kuroyukihime's Huge Girl. He barely reaches to her waist.
- Ugly Guy, Hot Wife: While they aren't married, he has this with Kuroyukihime. Haruyuki is a fat midget and just not attractive in the conventional sense, while Kuroyukihime is a beautiful Aloof Dark-Haired Girl who somehow loves him regardless of his looks. Haruyuki himself has a very hard time believing his luck.
- Ultimate Showdown of Ultimate Destiny: In the volume 10 side story "Versus", Haruyuki fights Kirito. Who won? Neither. Did you actually expect anything less?
- Winged Humanoid: His avatar Silver Crow can grow wings making him this.
- Wing Pull: Silver Crow has a set of retractable fins (replaced by sheets of High-Tech Hexagons in the anime) which slow his fall, and can be used to fly by expending his special move gauge. In volume 8 he develops the second-order Incarnate technique "Light Speed" which transforms them into bird wings made of Pure Energy, allowing him to fly even when his meter is empty.
- You Are Better Than You Think You Are:
- Haruyuki has zero self-confidence and he thinks he can only be pitiful loser, at least until Kuroyukihime tells him of the great potential she sees in him and how she believes he will become the greatest Burst Linker of all. Haruyuki then decides that even if he still can't believe in himself, he can believe in Kuroyukihime's faith in him.
- Chiyu also tells Haru this when he meets with her at her apartment, telling him of all the nice things he did for her and he doesn't have to feel so bad about himself.
- You Are Not Alone: He tells Kuroyukihime that she's not alone after learning how her sister betrayed her and manipulated her into killing Red Rider, promising to stand with her as she reunites Nega Nebulus, builds it even larger, and finally confronts her sister.
A second-year at Umesato Junior High who is very popular among the other students thanks to both her looks and passive personality. She becomes interested in Haruyuki and gives him the chance to enter the Accelerated World to fight alongside her. During school, she is known for being very calm and caring but still impatient and ill-tempered and not always using her head.
She is actually the Black King, formerly one of the original pure colored kings, who went into hiding, Like the others she is one of the strongest players in the game with a level 9 avatar. She is considered a traitor by other Burst Linkers.
- Absolute Cleavage: Her net avatar's dress takes this to its logical extreme. Her bodice is entirely backless and sideless, with two narrow straps of black fabric rising from the waistline to cover her non-existent boobs.
- Action Girlfriend: Kuroyukihime is the powerful Black King who suddenly changes Haruyuki's life by introducing him to the Accelerated World, becoming both his mentor and love interest.
- A-Cup Angst: Downplayed. She's usually not bothered by the size of her chest, but she gets annoyed when Niko tries to make fun of her lack of curves and when seeing Megumi's large breasts.
- Affectionate Nickname: Fuuko, Utai and Akira address her as Sa-chan ("Sacchi" in the localization of the light novel). As Black Lotus, her mentor Graphite Edge calls her "Lotta".
- All Amazons Want Hercules: An unusual example. She became enamored with Haruyuki after seeing his speed and drive in his squash games, and the only reason she had a higher score, for the purpose of getting his attention, is she had to cheat to even surpass him. The way it's presented, this in turn makes Haruyuki an unusual kind of "Hercules", but replace physical prowess with video game skill, though within a virtual game world, it still translates to physical prowess in a sense.
- Aloof Dark-Haired Girl: She's a tall girl with long black hair who possess a graceful and calm demeanor.
- Ambition Is Evil: Treated as the highest criminal in Brain Burst for trying to reach Level 10 and disrupting the Balance of Power. Subverted by the show itself, which treats her overt desire to achieve level 10 and potentially end the game as good, while treating the other kings' underhanded backstabbing and maintainance of the status quo as evil.
- Also subverted in the books with the non-Guild Burst Linkers (and secretly a few Guild members too), who see her ambition as the natural state of mind for a true gamer and fighter; when Kuroyukihime appears at the Hermes Cord Race (book 5) many of the spectators cheer for her return.
- Anguished Declaration of Love: Towards Haruyuki in Episode 4.
- Animal Motifs: Always associated with butterflies.
- Armor-Piercing Question: A surprisingly heartwarming one in Volume 2. After pointing out that his fear of failure is holding him back, and at the root of it is the fear of being abandoned, asks him if he really thinks their bond is that shallow.
- Armor-Piercing Slap: Slaps Haruyuki and cries after he accuses her of using him as a pawn to degrade herself.
- Attractiveness Isolation: Kuroyukihime fears she's so attractive that she's intimidating Haruyuki and that's why he's so reluctant to get close to her.
- Badass Adorable: Very beautiful, School Idol to boot and is the Black King, who made her descent in the virtual world through piles of her defeated enemies.
- Beware the Nice Ones: Although she is generally polite and well meaning, she won't hesitate to kick ass if Haruyuki and his friends are in danger.
- The Big Girl: Besides playing The Leader, Kuroyukihime is also by far the most powerful and toughest member of Nega Nebulus.
- Blade Below the Shoulder: The Black Lotus's arms have absurdly sharp blades that are able to cut and damage anything.
- Blade Spam: Her attacks "Death by Barraging" (performed with her arms) and "Death by Bashing" (a series of kicks too fast to see), as well as her Incarnate techniques like Starburst Stream (which generates stars around her and shoots them forward as she strikes).
- Breaking the Fellowship: The Elements of Nega Nebulus broke up after the failed attempt to invade the Imperial Palace, since three out of four were trapped at various spots in the Unlimited Neural Field.
- Broken Ace: In the real world, she's the attractive, popular and intelligent vice president of her middle school. In the accelerated world, she's currently the closest to reaching Level 10, as the only Level 9 who's killed another Level 9. Beneath this seemingly perfect exterior lies a surprisingly emotionally vulnerable girl who's plagued by guilt, self-loathing and occasional feelings of jealousy.
- Butterfly of Doom: Anti-Hero example.
- Cain and Abel: She considers her sister White Cosmos her worst enemy because she tricked her into beheading Red Rider.
- Character Development: aiming for this in-universe. Kuroyukihime is working towards being able to change the tip of her blade-arms into hands, with the immediate aim of holding Silver Crow's hand, the long-term aim being to hug her friends in the Accelerated World without killing them - remember, her closest range attack is called Death by Embracing. This process involves analyzing the wounds and flaws in her own psyche, and working to fix them - and she can already form hands for a few seconds. It's a literal manifestation of The Power of Love; not just her romantic love for Haru, but her platonic love for her friends in her Legion.
- Child Hater: She says she dislikes children, especially those like Niko.
- Clingy Jealous Girl: She easily gets jealous whenever another girl gets close to Haruyuki. This even extends to herself as the second ending shows.
- Cool Big Sis: Despite her claims of hating kids, she acts very mentor-ish around Coral Merrow and Lagoon Dolphin, and seems to enjoy their company. Meanwhile, her interactions with Niko are part this and Vitriolic Best Buds.
- Counter Attack: Guard Reversal, aka "the way of the flexible" - a martial arts technique she picked in the real world for redirecting the force of opponents' attacks. The first time she uses it against Haru, he momentarily feels like her blade arms have turned into snakes and wrapped around his punch. Haru is later able to pull off a crude version of the technique by imitating her.
- Cry Cute: After she and Fuuko/Sky Raker finally mend their broken friendship.
- Dark and Troubled Past: She says her "parent" betrayed her and is now her worst enemy. It's later revealed that her "parent" is her sister who tricked her into killing Red Rider.
- Dark Is Not Evil: She has a black motif and is seen as highest criminal in Brain Burst. In actuality, she's an Anti-Hero, but not a bad person.
- Deadly Hug: Her attack Death By Embrace, a hug that decapitates her enemy.
- Declaration of Protection: She swears to Haruyuki that she will protect him right before saving him from being hit by Araya's car.
- Deus Exit Machina: She is in a school trip during the Dusk Taker arc, which results in Haru and Taku having to deal with Noumi alone.
- Designer Babies: In Volume 23, it is revealed she is a Machine child. Her mother was one of KAMURAs entrepreneurs and her father one of the researchers and together they were trying to research Fluctlight duplication by overwriting her Fluctlight when she was in her artificial womb by attaching a baby-size Neuro Linker on her when she was still developing.
- Distaff Counterpart: Given that Accel World is technically a Spiritual Successor to Sword Art Online, Kuroyukihime can be thought of in many ways as a female Kirito. This has been lampshaded in crossovers such as Accel World vs Sword Art Online: Millennium Twilight. Both of them favor wearing black, have titles with the word "Black in them (Black Lotus and Black Swordsman), are very The Stoic and serious compared to their peers, both are capable of Dual Wielding, and both even use identical Sword Skills (Vorpal Strike, The Eclipse, Starburst Stream).
- Don't Call Me "Sir":
- She doesn't like how Haruyuki keeps calling her "Sempai", even after she revealed her true name to him.
- She also would like Takumu to stop calling her "Master" because she likes to be in more friendly terms with her legion members.
- Establishing Character Moment: She has three in the first volume. Her first appearance as someone who broke Haru's record in the squash game (albeit using acceleration) and inviting him to soar to greater heights shows her as a mysterious individual who's also a skilled gamer. Her emotional breakdown after Haru insults himself and her shows that she's still an emotionally vulnerable 14-year-old. The fact that her plan to get Araya expelled backfires on her, resulting in him trying to kill her and Haru, shows that many of her actions end up having unintended and unfortunate consequences.
- Even the Girls Want Her: Megumi appears to.
- The Fashionista: Not only is her net avatar's dress very fancy, but in the real world, she wears casual clothes, kimono or gloves.
- Fire-Forged Friends: She and Chiyu initially don't get along because they're jealous of each other, but by the end of the Dusk Taker arc, during which Chiyu contacts Kuroyukihime to inform her about Haru's stolen wings, enabling her to come to the rescue, they warm up to each other, and Kuroyukihime starts calling Chiyu by her first name.
- First-Name Basis: She refers to Haruyuki and his friends by their (unabbreviated) first names, and the "-kun" honorific, and forgoes honorifics with Fuko and Megumi.
- Flat "What": When she realizes that Haruyuki actually went with her suggestion to direct link with Chiyuri (which is equivalent to a very close date) to investigate Cyan Pile, her expression goes to a fault.
- Foil: To Taku's (unnamed) Parent. Kuroyukihime serves as a mentor and guide to Haru, while Taku's Parent told him what to do and used him as a pawn to test the backdoor program.
- Freakiness Shame: She thinks her Duel Avatar is ugly because her limbs are blades instead. Haruyuki finds it beautiful, though.
- Give Geeks a Chance: She's a very beautiful girl who is so popular that she could have every guy at her school, but she only has eyes for the little chubby guy that everyone considers a loser.
- Godlike Gamer: As one of the seven Kings and a level-nine Burst Linker, Black Lotus is undoubtedly one of the most powerful Burst Linkers in the entire game.
- Green-Eyed Epiphany: She says she realized her feelings for Haruyuki when he mentioned that he has cabled with Chiyu with a short cable and Kuroyukihime found herself feeling jealous for the first time in her life.
- Hair Antennae: They fit with her butterfly motif since they resemble butterfly antennae.
- Hair Decorations: Her net avatar wears a headband.
- Hellish Horse: She pulls a Big Damn Heroes while riding one of these.
- Heroic BSoD: She faints after being forced to remember how she killed Red Rider.
- Heroic Sacrifice: Used Physical Full Burst to save Haruyuki from being hit by Araya's car, consuming 99% of her Burst Points and causing her a few days' retirement at the hospital.
- Heroic Self-Deprecation: She's often fairly critical of herself for her past actions, and the narrator in her POV sections (which is indicated to show how she feels) can often judge her quite unfavorably.
- Impossibly-Low Neckline: In her net avatar.
- Iron Lady: Takes on a haughty and flippant persona when speaking officially as the Black King, making aggressive demands and implying that her rivals are only still alive because she allows it. Raker claims that this act helped recruitment greatly in the early days of Nega Nebulus... because Lotus used to be so bad at it that recruits saw her as an Adorkable Plucky Girl and treated her Legion as a fan club.
- It's All My Fault: She blames herself for many things, such as the disintegration of her own Legion. (on the last charge, at least, her former Legion members don't agree)
- Just the Way You Are: She loves Haruyuki for how he is. For instance, she likes the pig avatar he uses and finds it cute.
- Lady and Knight: Kuroyukihime is the beautiful lady and Haruyuki is the brave warrior trying to make himself worthy of being her knight and protect her.
- Lady of War: Her Duel Avatar glides around just above the ground, giving her movements a smooth, graceful quality, and she carries herself in a calm and elegant manner.
- The Leader: Of her legion Nega Nebulus. She gives them missions to protect territories, and guides them on getting stronger.
- Leitmotif: "Alert Sign" in the anime. During her battle with Yellow Radio it's replaced by the "raio0" remix.
- Light Feminine and Dark Feminine: The dark to Chiyuri, Megumi and Fuuko's light.
- Lightning Bruiser: Black Lotus is insanely fast, deals borderline One Hit Kills against weaker Duel Avatars, and is immune to grapples and restraining attacks.
- Loophole Abuse: Because the Umesato dress code requires an "uncolored" uniform shirt and black isn't a color, she's able to get away with wearing a black shirt. It's unclear how she does the same by wearing a dark blazer instead of a blue one with her winter uniform, though.
- Meaningful Name: Her nickname, Kuroyukihime, translates to Princess Snow Black. You can already guess what she ended up being...
- A Mother to Her Men: She deeply cares about the members of her legion and treats them like her dear friends instead of mere subordinates.
- Ms. Fanservice: Her net avatar wears a revealing dress that shows off her cleavage, her back and part of her butt. The anime opening sequences also like to show her nude.
- Multiform Balance: Her "Overdrive" command causes Black Lotus's Tron Lines to glow in one of three colours, temporarily converting it into an avatar of that colour - Mode Red for increased attack range, Mode Green for higher defences, and Mode Blue for improved melee attack power. It's referred to as not a true Incarnate ability so much as a battle cry she uses to hype herself up, and is only usable in multiple ways because her avatar isn't associated with any colour to begin with.
- My God, What Have I Done?: Her reaction after realizing that Red Rider hadn't actually been planning on manipulating and betraying the other legions, meaning she killed him over a lie.
- Nice Girl: Kuroyukihime is very polite, calm, patient and well-meaning. You better don't make her angry, though.
- Non-Uniform Uniform: For apparently no reason at all, she wears a darker version of the school uniform. It does fit her nicely though.
- Only Known by Their Nickname: To readers/viewers, as there are a few characters who know her name. Although she states that her real name isn't that different from her nickname. Taken to insane levels when she presents her name tag (which supposedly can't be hacked) and it shows her nickname instead of her name. Fuuko addresses her as Sa-chan in the final episode. It still doesn't tell us anything about her real name but is a start.
- O.O.C. Is Serious Business: When Haru makes the assumption that she's only around someone like him as a means of self-punishment, she gets upset to the point at which she slaps him, angrily calling him an idiot (as opposed to the smug way she calls him a "fool" when he does something stupid), and ends up crying uncontrollably. Seeing her as the 14-year-old girl she really is, Haru realizes how deeply he upset her.
- Parasol of Prettiness: In her net avatar goes around with an elegant parasol.
- Parental Neglect: Her parents don't even bother to show up at the hospital after she is hit by a car.
- Peerless Love Interest: Haruyuki pretty much fell in love with Kuroyukihime because she was way out of his league both in social status and looks. This makes Haruyuki determined to fight to prove his worthiness of her and protect her. However, this gets deconstructed as Kuroyukihime is not comfortable with Haruyuki idolizing her and would like him to treat her like an individual equal to him so they could enjoy a more normal relationship. Haruyuki constantly insisting on maintaining his distance from Kuroyukihime and admiring her from afar only ends up hurting her feelings, but Haruyuki still isn't confident enough to get closer to Kuroyukihime and accept that she loves him just the way he is.
- Personality Powers: Black Lotus's limbs are razor-sharp and hurt anyone who touches them, fitting her complexes over her past mistakes. As part of her attempts to move on, she is trying to develop an Incarnate technique which uses positive feelings to transform her blade-arms into normal hands.
- Pimped-Out Dress: Her net avatar has this.
- Power Gives You Wings: In the OVA, when she merges with Haruyuki.
- Proper Tights with a Skirt: She wears black tights while in her school uniform.
- Property of Love: She claims Haruyuki belongs to her and she won't give him away to anyone.
- Rapunzel Hair: Her hair is past her back.
- Raven Hair, Ivory Skin: She has very dark hair and pale skin and is seen as beautiful.
- Red Baron: Known by the title "World End"
- School Idol: She's the most popular girl in her grade, is considered the most beautiful girl in school and is part of the student council.
- School Uniforms Are the New Black: She wears her modified school uniform most of the time, and Fuko notes that her closet is full of uniforms.
- Sempai/Kohai: She is the sempai to Haruyuki and co.
- Sexy Backless Outfit: Her net avatar wears an entirely backless dress, but it's sexiness comes from the Absolute Cleavage in the front..
- Sexy Mentor: She's very beautiful and acts as The Tease towards her protege and Love Interest Haruyuki.
- She Is the King: She holds the title of the Black King.
- Shout-Out Theme Naming: To Magic: The Gathering - Black Lotus is the most iconic member of the game's premier Game Breakers, the Power 9, for its unmatched ability to gather mana (known colloquially as "Acceleration" or "Accel"). This is reflected both in Kuroyukihime's Level 9 status and the mechanics of her "Overdrive" command. The theme starts to become more obvious after the arrival of the fake Black avatar Black Vise (see his entry for more details).
- Shut Up, Hannibal!: When Yellow Radio tries to guilt trip her over her killing Red Rider, Kuroyukihime tells him that she won't feel at all guilty about killing Yellow Radio.
- Single-Target Sexuality: She only has eyes for Haruyuki.
- Snub by Omission: In the first OVA, while she's upset about Haruyuki acting like her subordinate while offering to help her alongside his other friends, says, "Then I'll see you after school, Takumu-kun, Chiyuri-kun," deliberately leaving Haru out.
- Spin Attack: Her ultimate Incarnate technique "The Eclipse" has her extend her arms and spin at high speeds while upside down, causing her to appear as a black void surrounded by a ring of white Sword Lines.
- Sword Beam: Her Incarnate technique "Vorpal Strike" shoots a powerful long-range beam by thrusting her arm forward, making it an exaggerated version of the reach-extending Sword Art Online skill of the same name. Haru later uses the image of Vorpal Strike as inspiration for Laser Lance, a long-range version of his Laser Sword, and the similarity of the two techniques means they can be used in a Combination Attack.
- Sword Cane: The parasol of her net avatar is revealed to be a scabbard for a sword in the OVA.
- The Tease: She enjoys to flirt with Haruyuki and see him get embarrassed as a result.
- Theme Music Power-Up: "Alert Sign" in the anime. During her battle with Yellow Radio it's replaced by the "raio0" remix.
- Tiny Guy, Huge Girl: Huge Girl to Haruyuki's Tiny Guy.
- Tragic Mistake: Killing Red Rider. It indirectly leads to her being kicked out of her family home after she confronts her sister, becoming a wanted criminal in Brain Burst, and, not long afterward, her team breaking apart after the failed raid on the Imperial Palace.
- Tsundere: Type B. Kuroyukihime is usually very calm, affectionate to Haruyuki and true with her feelings, but is prone to become very annoyed when she sees Haruyuki with other girls or when he does something that upsets her. Perhaps exemplified at the end of the Dusk Taker arc, in which she says that 49 percent of her wants to congratulate Haruyuki for a job well done, 50 percent of her wants to punch him, and the remaining one percent wants to hug him while apologizing for not being there for him.
- Tsurime Eyes: She displays these eyes and she has a confident and aloof personality.
- Ugly Guy, Hot Wife: Her relationship with Haruyuki, although they aren't married. Kuroyukihime, a very beautiful Aloof Dark-Haired Girl, somehow only has eyes for the fat midget Haruyuki and loves him regardless of his looks.
- Unwitting Pawn: It's later revealed that the reason she killed Red Rider was because her sister tricked her into thinking that he had nefarious motives for establishing the non-aggression pact. Once Kuroyukihime finds out the truth, she is furious.
- Vitriolic Best Buds: With Yuniko. They display animosity toward each other, because Yuniko has a hard time admitting she enjoys their company around her.
- Winged Humanoid: Her net avatar has large butterfly wings.
- Wings Do Nothing: The wings in her net avatar are mere decoration.
- Withholding Their Name: "Kuroyukihime" is Only Known By Her Nickname (Princess Snow Black). She claims that it's not that far from her real name, but refuses to say what it is, even going so far as to hack her student ID to read Kuroyukihime (something that other characters had previously thought to be unhackable).
- Zettai Ryouiki: Her avatar in the OVA.
Chiyuri "Chiyu" Kurashima/Lime Bell
Haruyuki's upbeat childhood friend who attends the same school as him. Although she is going out with fellow childhood friend Takumu, she cares a lot about Haru's wellbeing and is the first to show concern over his problems with bullies.
She is the only one without an initial avatar in the Accelerated World until she demands the program for herself and becomes Lime Bell.
- Absolute Cleavage: Her avatar in the OVA.
- Affectionate Nickname: Haruyuki and Takumu call her Chiyu.
- Amicable Exes: With Takumu. Even though they have broken up, they remain good friends and hold no ill feelings toward each other.

- Arm Cannon: As Lime Bell and weaponizes Cyan Pile in the OVA.
- Badass Adorable: As Lime Bell who is cute and a competent fighter.
- Badass Cape: As Lime Bell.

- Cat Smile: Does this on occasion with her net avatar.
- The Chick: She cares a lot about her friends, tries to get everyone in the team to get along and has healing powers.
- Childhood Friend Romance: Subverted. She's introduced as the girlfriend of her childhood friend Takumu, but she seems to be dating him just to maintain his friendship. They break up after the first arc, but remain friends.
- Childhood Friends: With Haruyuki and Takumu, who she has known for most of her life.
- Cute Bruiser: Her avatar Lime Bell can whop other players pretty hard with her bell.
- Cute Little Fangs: She has little fangs to go with her Cat Girl theme.
- Encounter Bait: Her "Acoustic Summon" ability, developed in volume 12, lets her use the sound of her bell to attract Enemies.
- Fake Defector: Joins up with Dusk Taker, an Avatar who can steal others' abilities, just so she could find a chance to restore Haruyuki's wings after they were stolen. Once she has sufficiently leveled up, discovered the true nature of her powers, and secretly tipped Kuroyukihime of the showdown with Noumi, she drops the act and restores Haruyuki's wings.
- Fighter, Mage, Thief: Lime Bell is the Mage to Cyan Pile's Fighter and Silver Crow's Thief.
- Fire-Forged Friends: She and Kuroyukihime warm up to each other around the time Chiyu contacts Kuroyukihime to inform her about Haru's stolen wings, enabling her to come to the rescue.
- Genki Girl: She's a very cheerful and energetic, at least when her friends are happy, but even then she still tries to be to cheer them up.
- Girl Next Door: She's Haru's upbeat childhood friend who lives in the same apartment building as him. Despite Haru trying to keep his distance from her due to getting bullied, Chiyu did her best to remain friends with him and never stopped trying to help him.
- Girliness Upgrade: Haru notes that she seems a bit more girly than usual after dating Taku, as shown by her sweater and skirt.
- Good Parents: Her parents care for her a great deal, and it's revealed that her father put the Neurolinker on her since her birth so that he, who had lost his voice as a result of hypopharyngeal cancer, could communicate with his daughter.
- Growing Up Sucks: She laments that her friends are drifting apart, and wants to ensure that they stay the way they are forever. Haru sadly tells her that they can't be kids forever.

- Light Feminine and Dark Feminine: The light to Kuroyukihime's dark.
- Little Bit Beastly: Her net avatar looks like her with cat ears and a tail.
- Meaningful Name: May or may not be intended, but her nickname "Chiyu" written in kanji means "healing" or "cure".
- The Medic: The third Avatar with healing abilities. Actually what she does is turn back a target Avatar's personal time to before they were injured.
- Naïve Newcomer: She thinks of the Accelerated World as a simple game at first, and wants to join so she can do it with Haru and Taku.
- Nice Girl: A kind girl who cares a great deal for her friends.
- Official Couple: With Takumu until the end of the first arc. The novels have Takumu saying, at the start of the second arc, that they've broken up. The anime omits this line, but keeps Haruyuki asking Takumu during third arc whether he wants to be Chiyu's boyfriend again. As a result, when and why they broke up isn't as clear in the anime.
- Personality Powers: Was at her happiest in her childhood, when her father was still alive and she and her friends were schoolmates with no barriers between them. As a result she gains time-reversal powers from a bell that sounds just like the one at her old school.
- Red Baron: Known by the title Time Witch.
- Red Herring: In the first arc, Chiyuri is suspected of being Cyan Pile, the Burst Linker who was targeting Kuroyukihime to get her points. Chiyuri turns out to be innocent and Cyan Pile is Takumu, who installed a virus in her neuro-link.
- The Resenter: She admits to be jealous and resentful of how Kuroyukihime got close to Haruyuki and solved his problems so quickly, since Chiyuri had been trying for a long time to help Haruyuki with his problems but never accomplished it. However, Chiyu recognizes Kuroyukihime is the one who can truly help Haruyuki and gives them her blessing.
- Shipper on Deck: She was initially distrustful of Kuroyukihime because she feared she was trying to use Haruyuki for her own gain and wanted her to stay away from Haru. After she understands Kuroyukihime is the only one who can help Haru with his problems, Chiyu decides to support their relationship and encourages Haru to become her boyfriend, if only so that their relationship is on equal terms.
- Spotting the Thread: She finds it strange that Kuroyukihime is fairly knowledgeable about the White Legion's possible headquarters, even though they're so far away from Nega Nebulus. Haruyuki notes that Chiyu's this close to finding out that Kuroyukihime's older sister is the White King, something Kuroyukihime has only told Haru.
- Stone Wall: Unlike most Duel Avatars, Lime Bell can smash through walls without taking Scratch Damage, which is quite a feat, considering most early healers are Squishy Wizards.note Thus, she can charge up her killer move gauge without even fighting. The effectiveness of her time reversal abilities plus her incredible defense (though not yet on Green Grandee's level) makes her the ideal healer. But that still remains to be seen until White Cosmos appears.
- Sweater Girl: She wears a white sweater with a pink skirt when Haru visits her at her apartment in Volume 1, which Haru notes is more girly than usual for her.
- Throw the Book at Them: She does this in behalf of Takumu's suggestion to show her how the Burst Link works.
- Time Master: She's able to turn back a target Avatar's personal time.
- We Used to Be Friends: All she really wanted was to stay friends with Haruyuki and Takumu, and is extremely depressed about seeing the three of them drifting apart. They eventually get better.
- Zettai Ryouiki: Along with her school uniform in the manga. Also, her avatar in the OVA.
Takumu "Taku" Mayuzumi/Cyan Pile
Another childhood friend of Haruyuki and Chiyuri, the latter whom is his current girlfriend. He used to attend a prestigious school before transferring to be with his two childhood friends. Often takes part in kendo tournaments.
He is soon revealed to be Cyan Pile, a Burst Linker who was targeting Kuroyukihime to get her points. After being defeated by Haruyuki, Takumu decides to change his ways and joins Nega Nebulus to atone for his sins.
- Academic Athlete: He's the top student of his class and the kendo team champion. However, he owes his success to using the Brain Burst to cheat.
- Adaptational Heroism: A minor case, but in the anime, after Haru defeats him, and calls him out on asking Haru to let him win so that he won't be kicked off Brain Burst, while he was planning on doing the same thing to Kuroyukihime, Taku admits Haru has a point.
- Affectionate Nickname: Haruyuki and Chiyuri call him Taku.
- Amicable Exes: With Chiyuri. They break up after the first arc, but there are no hurt feelings between them and manage to remain good friends.
- Arc Villain: For the first few episodes, he's the one who's trying to cash in on the bounty for Kuroyukihime.
- The Atoner: After being defeated by Silver Crow, he shows evident aspects of this, trying to make up for his past behavior.
- Awesome, but Impractical: His Level 3 special attack "Spiral Gravity Driver" is devastatingly powerful but takes a long time to execute, can only be aimed straight down, and sometimes leaves his weapon stuck in the ground. Taku regrets blindly following his parent's advice to take so many special attacks, but takes responsibility for his own decisions.
- Bash Brothers: Post-HeelFace Turn, with Haruyuki.
- Broken Ace: He is friendly, smart, athletic... pretty much everything Haru wishes he was. But as it turns out, he was bullied by his seniors in his earlier days. This ultimately drove him to do anything to one day get back at them and use Brain Burst to cheat his way through the exams and the kendo tournaments. It gets even worse when he gets an ISS kit.
- Butt-Monkey: In the Accel Assault OVA. The main story has a milder variation, in that Cyan Pile tends to die or get his limbs cut off to show how strong his opponent is.
- Can't Catch Up: Volumes 7 and 8 delve into Taku's feelings of inferiority after seeing how far his teammates have grown, exacerbated when he gets infected by an ISS kit and it starts feeding on his negative emotions.
- Chest Blaster: Cyan Pile's Splash Stinger shoots needles from panels in his chest.
- Childhood Friend Romance: He has a crush on Chiyuri and they're dating until the end of the first arc.
- Childhood Friends: With Haruyuki and Chiyuri.
- Crazy Jealous Guy: Pre-HeelFace Turn. There's something of a variation on his trope, since he claims that getting together with Chiyu is in her best interests, so that she doesn't spend the rest of her life taking care of Haru.
- Defeat Means Friendship: After Haru defeats him in their duel, Haru convinces him to join Nega Nebulus so he can start over and rebuild his friendships with both him and Chiyuri from the ground up.
- Driven to Suicide: He mentions that he was seriously considering killing himself while he was being bullied.
- Easily Forgiven: Believes this trope has been put on him. He betrayed his friends, laid a brutal No-Holds-Barred Beatdown on Haruyuki, and used a cheating method to stalk Kuroyukihime for her points. Despite this, both Haru and Kuroyukihime forgive him almost instantly after he apologizes (although Haruyuki doubts whether sparing him is the right decision), and Chiyuri only insists on a ridiculous amount of ice cream to forgive him. It actually seems to boggle him at first, and arguably is part of what makes him so selflessly defend these people who accepted him at his worst.
- Embarrassing Nickname: He hates the nickname "Professor."
- Fairytale Motifs: His standard avatar bears more than a slight resemblance to the Tin Woodsman.
- Fatal Flaw: His insecurity and occasional self-destructive tendencies when trying to make up for something often cause him to make bad decisions, such as planning on giving up all his points to Haru and getting an ISS kit.
- Fighter, Mage, Thief: Cyan Pile is the Fighter to Lime Bell's Mage and Silver Crow's Thief.
- Four Eyes, Zero Soul: Inverted. Prior to his HeelFace Turn, Takumu uses the enhanced abilities granted by Brain Burst to correct his vision. Post-HeelFace Turn, he begins wearing his glasses again, showing that he's no longer relying on artificial means to improve himself.
- Green-Eyed Monster: Initially, he resents and is jealous of Haruyuki for getting Chiyuri's attention by making her constantly worry about him, and goes so far as to put a backdoor program on Chiyuri's Neurolinker to keep tabs on her. He gets better.
- HeelFace Turn: When he leaves his legion to join Kuroyukihime's.
- Huge Guy, Tiny Girl: Huge Guy to Lime Bell's Tiny Girl in the Accelerated World.
- Hypocrite: On the verge of defeat against Haru, he begs Haru not to kill him, saying that if he loses against a Level 1 at Level 4, he'll lose all his points... which is what he was planning on doing to Kuroyukihime. In the anime, after Haru calls him out on this, Taku admits that he has a point.
- I Let You Win: In the extra chapter of the manga, Chiyuri, with Kuroyukihime as her partner, has to win a doubles match of tennis against Taku and Haru for Taku to install Brain Burst on her. After the girls win the first set, Kuroyukihime notices that the guys are holding back, and, suspecting that this trope is the reason Taku isn't playing at his best, calls him out on it, saying that Chiyu wants to face him at his best.
- Inferiority Superiority Complex: He believed he had to be the best at everything so he wouldn't get bullied and Chiyuri would stay interested in him. This lead to him using Brain Burst to get good grades and become the kendo team star. He later starts to grow out of it as part of his Character Development.
- Innocent Innuendo: A minor Running Gag, particularly in the anime. He refers to Kuroyukihime as "Master", and some of his conversations with Haru have been sufficiently vague that eavesdroppers mistook one for a love confession. Then there's the Accel Assault OVA where he gasps as Chiyu shoves her fist inside him. His avatar even attacks by impaling enemies on an extending spike.
- I Want My Beloved to Be Happy: He notes that he and Chiyuri probably can't go back to being boyfriend and girlfriend, but he'll do his best to make her happy.
- Jack-of-All-Trades: Spent some of his level-up bonuses on, among other things, gaining new attack forms; while this makes Pile more flexible, he's not as powerful as avatars who focus entirely on one ability like his teammates.
- Jerkass Has a Point: Haru realizes that as cruel as Taku's claims about Haru being dependent on Chiyu are, he can't completely deny them.
- Kirk Summation: Gives one to Noumi in response to Noumi's Hannibal Lecture. Taku suggests that Noumi's avatar's ability to steal powers repesents the void in his heart. Taku isn't completely wrong, given that the powers are based on one's traumas, but Noumi then takes the opportunity to describe how he got it.
- The Lancer: Post-HeelFace Turn he helps Haruyuki level up thanks to his greater experience and skills. Also a literal lancer since his weapon is a pile driver, which acts much like a spear.
- Lightning Bruiser: Cyan Pile can actually keep up with Silver Crow despite its large frame. Turned Up to Eleven once he acquires Cyan Blade.
- Master of None: In volume 7 Taku reveals that he sees his avatar as this, claiming that its nature as a melee-focused blue avatar was "distorted" by his mixed feelings of friendship and jealousy towards Haru and Chiyu. Haru disagrees, seeing Pile's Jack-of-All-Trades nature as a virtue that's helped out the Legion whenever they were facing unknown enemies.
- Meaningful Name: The "pile" refers to the piledriver that serves as his avatar's weapon.
- Mistaken for Gay: He and Haruyuki share a rather Ho Yay moment in Episode 21 and the girls around them seem to be misinterpreting the situation.
- Multi-Melee Master
- Cool Sword: Cyan Blade, thanks to his Incarnate System training with Scarlet Rain.
- Pile Bunker: His main weapon. Much to Haruyuki's surprise during his battle against Cyan Pile, his pile bunker can be used (albeit less efficiently) in mid/long-range combat, being particularly useful in tight spaces such as corridors.
- Mutual Envy: It turns out that while he outwardly seems to be everything Haru isn't- popular, good at school and athletic- he's actually jealous of Haru's inner strength.
- Nice Guy: Turns into this thanks to Character Development.
- Not So Different: With Noumi and Haru.
- In the Dusk Taker arc, he soon realizes that Noumi is relying on Brain Burst for an advantage in school and kendo, noticing Noumi's suspiciously perfect scores on one of his tests. It's also revealed that he, like Haruyuki, was bullied a great deal.
- Later on, it becomes clear that he and Haru are somewhat similar, having been victims of bullying in the past, and also prone to self-loathing.
- Official Couple: With Chiyuri until the end of the first arc. The novels have Takumu saying, at the start of the second arc, that they've broken up. The anime omits this line, but keeps Haruyuki asking Takumu during third arc whether he wants to be Chiyu's boyfriend again. As a result, when and why they broke up isn't as clear in the anime.
- Personality Powers: Cyan Pile was born from Taku being bullied in kendo practice by older students practicing thrusts on his neck. Later he claims that reason his melee avatar has reach-extending attacks is because of his mixed feelings of wanting to bring his friends closer and push them away.
- The Professor: Niko's nickname for him. Eventually sticks and is occasionally used by everybody else around him too. He doesn't like it, though.
- Sensitive Guy and Manly Man: The Manly Man to Haruyuki's Sensitive Guy.
- The Smart Guy: He knows a lot about Brain Burst.
- Smart People Wear Glasses: He's pretty knowledgable, and deliberately wears glasses to looks this way. Yukino nicknamed him "The Professor" because of this.
- Stalker with a Crush: He installed a virus in Chiyuri's neurolink so he can spy on her at any time. After his HeelFace Turn, he realizes how wrong this was and uninstalls the virus.
- Suicide by Cop: Thankfully, only in the game, but after realizing how much the ISS kit has corrupted him, Taku asks Haru to destroy him, and plans on going on a suicidal attack against the Acceleration Research Society after their duel concludes
- Talking Weapon: In the OVA, he turns into an Arm Cannon for Chiyuri.
- This Is Your Brain on Evil: In volume 7, after Taku is forced to equip an ISS Kit out of self-defence, he knows exactly how it works and can feel it slowly digging its tendrils into his mind. This mix of self-awareness and despair actually makes his IS Mode stronger than those of linkers who treat the Kit as a mere powerup, and instead of just granting him the default "Dark Shot" and "Dark Blow" attacks, it also lets him use darkness-empowered versions of Cyan Pile's usual abilities.
- Took a Level in Kindness: Though at the cost of exposing his issues, Takumu learns the error of his ways and becomes a much better person and a good true friend to Haru and Chiyu.
- Trauma Button: People using piercing attacks in kendo brings the traumatic memories of his being bullied back. According to him, it's bad enough that when he gets into high school and piercing attacks are allowed in kendo matches, he'll no longer be able to compete.
- Walking Spoiler: It's hard to talk about him without spoiling the fact that he, not Chiyu, is Cyan Pile (the main twist of the first volume), the less pleasant aspects of his personality that his friends don't know about, or that he eventually becomes a better person
- The Worf Effect: Having the biggest and strongest-looking avatar on your team is tough. It eventually takes its toll on him, and he begins questioning his own worth.
Fuuko Kurasaki/Sky Raker
A "retired" Burst Linker. She is Ash Roller's "parent", the only person in Accel World he shows respect towards. She semi-returns to Nega Nebulas at the end of volume 4 and fully returns to active duty at the end of volume 5.
Her avatar is Level 8, and she is pretty competent in a fight, although she prefers to play defensively.
- Adaptation Dye-Job: In the light novel, Fuuko is illustrated with brown eyes while the anime illustrates her with blue eyes.
- An Arm and a Leg: Got her avatar legs cut off by a reluctant Black Lotus, in hopes it will allow her Enhanced Armament to make real flight possible.
- Ambiguously Bi: She has a great deal of Les Yay with Kuroyukihime, but also gives Haru a peck in the Accelerated World after she regains her legs and experiences flight with his help. Haru's a distant fourth based on Fuko's rating system of how much she wants to make that person her Child- he gets a 100, Utai gets a 200, Rin(her actual Child) gets an 1,000, and Kuroyukihime gets a whopping 100,000.
- Artificial Limbs: In real life, she has artificial legs, the result of a hereditary condition that normally would have been cause for an abortion- as such, Fuko wondered why her parents gave birth to her. It is also what caused her Duel Avatar to manifest its jetpack: Gale Thruster.
- Beware the Nice Ones: Haruyuki's surprised to hear that someone as apparently kind as she is threw a PKer into a Legend-class enemy's territory.
- Blow You Away: Among the Elements, she is associated with the element of Wind.
- Call of the Wild Blue Yonder: The origin of her avatar, reflected in both its abilities and colour.
- Friendly Rival: With Blood Leopard.
- The Gadfly: Haru notes that she's one of the few people who can put Kuroyukihime on the defensive.
- Handicapped Badass: Is a competent fighter in Brain Burst despite losing the use of her avatar's legs.
- Hime Cut: Her duel avatar has a hair style like this with its straight bangs and long length in the back. Interestingly enough, while she is Japanese, her avatar is styled more like an English lady.
- Jet Pack: Her Enhanced Armament, Gale Thruster.
- Lady of War: Soft-spoken and elegant, but one of the most feared fighters in the Accelerated World.
- Light Feminine and Dark Feminine: The light to Kuroyukihime's dark.
- Mercury's Wings: When she drops the dress and sunhat, her avatar includes a tiara that gives her wings on the sides of her head. Her legs also had small winglike structures emerging from the calves.
- Nice Girl: Very kind and polite to everyone, even her opponents.
- Nice Hat: Her avatar Sky Raker wears a sun hat.
- Not Disabled In VR: Played with. She is legless in real life, but able to live normally with prosthetics. Her avatar on the other hand looks a lot like a person in a wheelchair and has lost its legs ever since Kuroyukihime severed them on Raker's request. However, her abilities are not any worse than the other avatars, which makes it a straight example after all.
- Not Quite Flight: Sky Raker is the Duel Avatar closest to ever fly, until Silver Crow gains actual flying ability. The fifth novel reveals the reason for this. Rather than flight Sky Raker's abilities are optimised for space-based combat and maneuvering. She just never had a chance to realise this until the sky elevator was added to The Accelerated World
- Personality Powers: Born with no lower legs due to a genetic condition, she grew up wondering why her parents had even chosen to have kids. The first time she felt at peace was after reading a sci-fi book about humans who adjusted to life in zero gravity by using genetic engineering to replace their legs with a second pair of arms. This lead her to dream for a while of flying through space herself, where her disability would be meaningless, though by the time she installed Brain Burst she was no longer aware of it.
- Person of Mass Destruction: Her effectiveness in territorial battles can be equated to that of a weapon of mass destruction.
- Rapunzel Hair: Her hair goes past her waist.
- Red Baron: Earned the nickname of "ICBM" for her ability to Speed Blitz entire teams by jumping behind enemy lines (often with another strong fighter in tow). For her failed attempts at achieving true flight, she also came to be known as "Icarus".
- She-Fu: Before losing her legs, her fighting style included a lot of acrobatics and precise palm and heel strikes, plus using Gale Thruster to ram enemies.
- Sink-or-Swim Mentor: She teaches Haruyuki by throwing him off from the top of the Old Tokyo Tower and letting him figure out how to use the Incarnate System to climb his way up.
- Sixth Ranger: After she rejoins Nega Nebulus.
- Tornado Move: Her Incarnate technique "Swirl Sway" creates a sparkling green tornado.
- True Blue Femininity: Her avatar's armour varies between deep blue and grey depending on the light, and it's also the most obviously feminine of any in the Legion.
- We Used to Be Friends: With Kuroyukihime/Black Lotus, since they both regret Black Lotus cutting off Sky Raker's limbs to enable her to fly. They start speaking again at the end of Volume 4, but don't fully reconcile until Volume 5.
- Woman in White: Her avatar Sky Raker wears a lot of white clothes.
- Zettai Ryouiki: She always wears thigh-high stockings to protect her prosthetics. Her duel avatar also evokes this image when its legs are intact.
Utai Shinomiya/Ardor Maiden
A Level 7 Burst Linker, fourth-grade schoolgirl, fire-elemental fighter, and another ex-member of the Elements. Near the end of volume 6 she rejoins Nega Nebulas.
- Affectionate Nickname: She's known as "Uiui" by Kuroyukihime and "Denden" by Graphite Edge.
- Arrows on Fire: Her "Flame Torrent" and "Flame Vortex" attacks.
- Awesome, yet Impractical: Her Incarnate skill allows for wide-range spells. The drawback is that it has a long charging time.
- Cute Mute: She's a very cute little girl and she can only communicate through her Neurolinker due to a trauma that made her lose her ability to speak.
- Cycle of Hurting: Like Current and Edge, she's unable to enter the Unlimited Neutral Field because her avatar's respawn point is stuck inside the "Instant Death" Radius of one of the strongest bosses in the game, which resulted in her repeatedly dying and respawning until her Neurolinker was physically disconnected. Attempting to return would place her back in this situation until she received a permanent Game Over. She is eventually rescued over the course of volumes 6 to 8.
- Dumb Struck: She lost her ability to talk due to the trauma of witnessing her brother's death, which also caused the pink parts of her avatar to turn red.
- Fastball Special: One of Nega Nebulus's regular strategies was to have Sky Raker use her Not Quite Flight to fling Maiden behind enemy lines, allowing her to rain Death from Above. They did this often enough for Lotus to crack jokes about Maiden being an Equippable Ally.
- Heal It with Fire: Can use the Incarnate System to generate flames with powerful purifying effects, which are first introduced as a possible way of separating the Armor of Catastrophe from its host.
- Hime Cut: Ardor Maiden has this hairstyle to go with her Miko theme.
- In-Series Nickname: "Ui" in real life, and "Mei" as Ardor Maiden.
- Keigo: In real life she communicates through very politely typed messages, though as Ardor Maiden her speech is a little more casual.
- Lava Pit: Her ultimate Incarnate technique "Purgatory Blaze" creates one of these to trap enemies and inflict ludicrous damage over time, at the cost of taking two full minutes to charge. It's something she developed for use against slow and sturdy targets, specifically the raid boss Genbu. Since wide-area destructive Incarnates are a manifestation of indiscriminate hatred, Mei's friends are alarmed to learn that she's been practicing such feelings and beg her not to use it too often for the sake of her own mind.
- Locked into Strangeness: In a system where avatars are normally themed around a specific colour, Maiden's stark red-white contrast is highly unusual. In fact the lower half of her avatar used to be pink, until witnessing the death of her brother in real life caused it to turn deep red.
- Magic Dance: Some of her Incarnate techniques are performed through a ritual dance, during which her bow transforms into a hand fan and a Noh-style mask slides over her avatar's face.
- Miko: Her Duel Avatar greatly resembles a shrine maiden.
- Not Disabled In VR: Is mute and cannot even perform "neurospeak" in standard VR (since it involves miming the action of speaking), relying on a virtual keyboard instead. Due to the deeper nature of Brain Burst's mental connection, however, as Ardor Maiden she can talk normally.
- Playing with Fire: Among the Elements, she is associated with the element of Fire, making use of a fire attribute bow and of Incarnate attacks that create both destructive and purifying flames.
- Rapid-Fire Typing: In real life (where she's incapable of speech) she's noted for her ability to type long, complicated messages very quickly and without typos.
- Red Baron: "Testarossa" and "Shrine Maiden of the Conflagration".
- Sacred Bow and Arrows: Her Enhanced Armament "Flame Caller", as part of her miko theme. However, when she's using her most "sacred" abilities it turns into a fan.
- The Speechless: As a result of a traumatic incident involving her brother's death, she can only speak the "Burst Link" command, and uses her Neurolinker to communicate.
- Tragic Dream: It's indicated that she wanted to be a Noh performer when she was young, but couldn't because she was a girl, and was not allowed to perform after a certain age, an experience that gave form to her duel avatar.
- Wham Line:
- She mentions a Burst Linker that took out Supernova Remnant, then identifies him as Cyan Pile.
- While talking about her older brother being her parent, she suddenly mention that he isn't just gone from the accelerated world, but he's also dead.
Akira Himi/Aqua Current
A mysterious Burst Linker that works as bodyguard for players no higher than Level 2. later revealed in the books to be one of the Four Elements of the old Nega Nebulus. She formally rejoins the Legion in book 14, after her Duel Avatar is rescued from the God-Level Monster Seiryu.
- Ambiguous Gender: While Akira herself is described as merely somewhat boyish, neither Aqua Current nor her standard net avatar have any distinct gender characteristics. As Current she also alters her voice slightly when around people she doesn't know, which tends to confuse those who meet her in real life. The fact that the name "Akira" can be used for either gender doesn't help matters.
- Big Damn Heroes: Saving Silver Crow from Argon Array.
- Chainmail Bikini: The shards of ice that form around her body in "Keen" form resemble one of these, though they're clearly not intended to be protective (she has other forms for that).
- Cycle of Hurting: Like Maiden and Edge, she's unable to enter the Unlimited Neutral Field because her avatar's respawn point is stuck inside the "Instant Death" Radius of one of the strongest bosses in the game, which resulted in her repeatedly dying and respawning until her Neurolinker was physically disconnected. Attempting to return would place her back in this situation until she received a permanent Game Over.
- De-Power: The reason why Aqua Current is level 1 - she went up against Seiryu and lost her levels. At the end of Volume 13, though, she levels herself back up to Level 4
- Elemental Armor: Her avatar isn't actually made of water, but transparent crystal that becomes almost invisible as long as the layer of water around it is intact.
- Expy: Of Sinon, with both being Rei Ayanami Expies who wear glasses in their civilian identities. Both also have Professional Killer titles, with Aqua being a Bodyguard and Sinon being a Sniper.
- Field Power Effect: Her avatar's "Aquamatic" trait (from aqua and chromatic) lets her enter a Super Mode with different properties depending on the stage she's fighting in. She eventually develops an Incarnate technique which lets her enter any of these forms regardless of location (see Multiform Balance below).
- Funny Animal: Her net avatar is an otter wearing glasses and a tie.
- Laser-Guided Amnesia: Does this to Haru saying it's too early for them to become friends. It is only possible for her to do it because of Incarnate System. Akira also tries to do this to Blood Leopard, but fails, and later comes to regret trying.
- Making a Splash: Amoungst the Elements, she is associated with the element of Water.
- Meaningful Name: Her last name "Himi" is read in Kanji as "looking at ice".
- Mega Twintails: As Aqua Current. Her first appearance in the novels depicts them as somewhat thinner.
- Multiform Balance: Her "Phase Trans" Incarnate technique lets her alter the phase of the water around her body, shifting into any of her possible Aquamatic forms. These are known to include "Keen" (a melee form with dual katars and light armour formed from ice), "Adamant" (another ice-based form with heavy armour) and a steam-based form specialising in ranged attacks.
- The Nicknamer: She calls Haru by his abbreviated first name, and also calls her Child and real life Cousin Mihaya, "Myah".
- The Spymaster: in the old Nega Nebulus, Current was in charge of intelligence gathering. Once she rejoins-the Legion, she reveals that she stays in touch with all her former bodyguard assignments, and they pass on all the gossip they've heard. Which is why Current has a clearer picture of the ISS crisis, and thus the Accelerated Research Society, than pretty much anyone else.
- Put on a Bus: Despite being featured in the opening of the anime she appears in one episode and vanishes after wiping Haru's memories of their meeting. Only reappears briefly in the cafe in the last episode after all is said and done. The Bus Came Back in the novels that haven't been adapted.
- The Quiet One: She doesn't talk very much.
- Red Baron: "The One" (a reference to her being an eternal Level 1) and "The Bodyguard".
- Rei Ayanami Expy: Has the bobbed hair, the unnatural eye color and the highly stoic and mysterious personality required for the trope. She only lacks the light hair color.
- Sci-Fi Bob Haircut: Fitting the futuristic setting.
- Scissors Cuts Rock: Being made of pure water (which has no charged particles to conduct electricity), Aqua Current is invulnerable to electricity despite Elemental RockPaperScissors stating otherwise.
- The Stoic: She's very straight-faced, and doesn't express emotions.
- Stoic Spectacles: In real life she wears glasses, which emphasizes her stoicness.
- Suggestive Collision: How she and Haru meet face to face when he crashes into her and accidentally grabs her breasts.
- Supernatural Gold Eyes: Has yellow eyes in real life, which makes her look even more mysterious.
A Level 8 Burst Linker with control over earth, as well as the fourth ex-Element. His appearance and fighting style bear a heavy resemblance to Kirito, protagonist of the author's previous work Sword Art Online.
- Badass Longcoat: His avatar's armor flares out at the waist to resemble one.
- Butt-Monkey: When both he and Black Lotus were in spitting distance of Level 9, Current tried to convince him to level up first so that she could learn about its permadeath mechanics, arguing that "Graph's in charge of sacrifices".
- Cast as a Mask: In Accel World Vs Sword Art Online his voice actor is only credited as "???", but it's heavily implied his voice actor is Yoshitsugu Matsuoka especially when listening closely to the modulated voice. This teases at the fan theories that Graphite Edge is Kirito himself.
- Computer Voice: His voice in Accel World vs Sword Art Online sounds very digital and is modulated, all in part to hide the identity of his voice actor.
- Cycle of Hurting: Like Maiden and Current, he's unable to enter the Unlimited Neutral Field because his avatar's respawn point is stuck inside the "Instant Death" Radius of one of the strongest bosses in the game, which resulted in him repeatedly dying and respawning until his Neurolinker was physically disconnected. Attempting to return would place him back in this situation until he received a permanent Game Over. It's later revealed that he was rescued by the Green King and joined his Legion.
- Dishing Out Dirt: Amongst the Elements, he is associated with the element of Earth.
- Dual Wielding: His enhanced armament, which are dual swords known as Lux and Umbra.
- Glass Cannon: His diamond swords have enormous attack power but his graphite armor is pathetically weak, to the point where even Squishy Wizard avatars can take him out in a few hits.
- Idiot Hero: When recounting the time Graph disintegrated himself while trying to attack a living sun, Current starts to refers to him as "that idiot" only to switch halfway through to "that reckless one".Niko: "Hahahaha! Just like Negabu's Anomaly! I've heard all kinds of rumours, and it sounds like he was seriously quite the mighty hero."Fuuko: "For him, you have to add the word idiot before hero, Red King." Fuuko smoothly uttered the adjective that Akira had hesitated to.
- Magic Is a Monster Magnet: Is Level 8 and could've gotten to Level 9 shortly before the 7 kings did, but chose not to in order to secure more fallback points. After the instant death rule was revealed he lost all interest in leveling up.
- The Mentor: He was the one who taught Black Lotus the Sword Skills she knows.
- My Future Self and Me: In Accel World vs Sword Art Online, the game heavily implied that he is Kirito from the future or at the very least connected to Kirito. When he meets Kirito, Graphite Edge already knows who he is without even being told his name, and has a very similar speaking pattern. There's also a long list of Suspiciously Specific Denial to things that Kirito brings up listed below.
- Red Baron: Despite his fragility his Hyper Diamond swords can parry almost any physical attack, earning him the nickname "Anomaly".
- Sour Supporter: His friends describe him as one of the most sour people you'll ever meet, implied to be because he keeps ending up as a vanguard and getting himself killed. Though this is as much a result of his Leeroy Jenkins habits as anything else.
- Suspiciously Specific Denial: In Accel World vs Sword Art Online, Kirito notices several things that seem familiar about Graphite Edge, including: the appearance of his two swords, his fighting style, the fact he taught Black Lotus the identical sword skills that Kirito uses, his preference of dressing in black with a Badass Longcoat, and the way he talks. However Graphite Edge keeps laughing it off as being it is all coincidence.
- Walking Spoiler: His true identity is kept under wraps, but there are numerous hints that have been dropped that he's Kirito or someone connected to him.
Chiaki's older brother. As one of the few who knew of Black Lotus' real-life identity, he admired and used to tell stories about her to his little sister. However, he perished three years ago due to an incurable disease passing the Brain Burst program on to Chiaki.
- Posthumous Character: Died when Chiaki was very young.
The former Red King and previous leader of Prominence.
- The Blacksmith: His "Arms Creation" ability lets him create permanent items that can be equipped by other avatars. These items also feature a "lock" in the form of his personal crest, which allows him to disable or destroy them remotely. Seeing the crest on the ISS kits makes Kuroyukihime wonder if he's responsible for them.
- Broken Pedestal: The reason Kuroyukihime attacks him is because she thought he was planning to use his gifts to the other Legions to forcibly uphold the nonaggression pact. It's subverted, as she realizes that she was tricked by her actual Broken Pedestal- her own sister and parent, Whtie Cosmos.
- Guns Akimbo: Before his death he wielded dual pistols named Helios and Eos.
- The Gunslinger: He resembled a cowboy.
- Heterosexual Life-Partners: Was this with Blue Knight before his death.
- Logical Extreme: Of red-type avatars, being one of the Pure Colours. In Lotus's words, his abilities may seem unconventional compared to someone like Scarlet Rain, but the true focus of Red avatars isn't firepower but range, and no weapon has longer range than one you don't need to be there to fire.
- Named Weapons: His dual Pistols: Helios and Eos.
- Nice Hat: His avatar features a nice cowboy hat atop his head.
- Nice Guy: All interactions show that he was one, though he may have been related to Acceleration Research Society.
- Ironic Nickname: Promotes peace but shares his name with one of the Horsemen of the Apocalypse: specifically, the warmonger.
- Off with His Head!: Courtesy of Black Lotus' Death By Embrace.
- Posthumous Character: Has since been deleted from the Accelerated World.
- Unorthodox Reload: His "Auto Reload" - a pair of hidden mechanisms in his forearms that slide new bullets into his guns without requiring him to change his grip. Their high speed means that he isn't left vulnerable even while using his weapons in melee.
Yuniko "Niko" Kozuki/Scarlet Rain
Red Rider's successor as the Red King, becoming by extension the leader of Prominence, and a fifth-grade schoolgirl.
- Adaptation Dye-Job: Her eyes are red in the anime adaptation. In the light novel, Haru describes them as being sometimes green depending on the light.
- Badass Adorable: She's an incredibly strong player in Brain Burst, and her cuteness is played as disturbing, by making her Cute and Psycho.
- Badass in Distress: In Volume 14 she's abducted by Black Vise, and Haruyuki and the others spend the next volume chasing her down.
- Bathtub Bonding: She tried to do this with Haruyuki, but failed and ended up in an Accidental Pervert moment.
- Combining Mecha: Her "Invincible" is composed of five separate Enhanced Armaments which combine together when summoned - the main body, cockpit, missile pods, thrusters and legs.
- Contralto of Danger: She puts up an act with a high pitched voice to seem cute so she can get closer to Haruyuki, but when she drops that facade her normal speaking tone is much more deep, gruff, and angry to emphasize her Little Miss Badass and Cute and Psycho character traits.
- Curtains Match the Window: She is themed around the color red so her hair and eyes were made a matching red to emphasize this. This is only in the anime however, in the light novel she's described as having green eyes.
- Cute and Psycho: Completely out for blood once she's in a fight, her cuteness as a little girl is used to contrast this to make her disturbing.
- Deliberately Cute Child: She's cunning enough to play up some cute mannerisms intentionally to (try) and get her way. Haruyuki even calls this "angel mode."
- Does Not Like Men: Not inside Brain Burst, but she claims to feel uneasy around men in real life - because the more time she spends living it up as the invincible Scarlet Rain, the more her real body feels weak and helpless.
- Easily Forgiven: Averted when she fires on Black Lotus, nearly killing her, during the battle with Chrome Disaster. While Black Lotus recognizes it as a poorly thought out Shoo the Dog moment, she still insists on an apology, and gets annoyed when Scarlet Rain gives a fairly perfunctory one.
- Enemy Scan: The sharp senses granted by her Vision Extension ability let her measure the "information pressure" exuded by veteran Burst Linkers (something distinct from their avatar's Character Level), allowing her to judge the other Kings' relative Power Levels and how long they've been around.
- Evil Laugh: Does this while raining down missiles on her opponents.
- Evil Makeover: In Volume 15, Invincible (minus its missile pods) is stolen by Cerberus III. Adjusting to its new user, it becomes a spiky purple biped with smaller guns, but clawed hands which allow it to fight in melee. Taken Up to Eleven when Cerberus is transformed into Wolfram Disaster, whose sleek organic body is completely unrecognisable from its original form.
- Fiery Redhead: When she drops her cute facade, she's shown to be incredibly Hot-Blooded and aggressive. Her red hair emphasize this.
- Fille Fatale: She wanted to recruit Haruyuki into Prominence and tried to use her cuteness to do so, she even tried to take a bath with him.
- Fire-Breathing Weapon: Oven Ray, one of Scarlet Rain's Incarnate attacks.
- Flash Step: One of her Incarnate skills, stated to be evidence that she runs from her problems.
- Gamer Chick: For Brain Burst, and western Shooters. She admits she can't imagine life without Brain Burst.
- Girlish Pigtails: She wears her hair this way intentionally to use her cuteness to her advantage.
- Good Eyes, Evil Eyes: Though not evil, her eyes shift from tareme to tsurime when she drops the Deliberately Cute Child facade.
- Hidden Depths: Despite her brash and fiery demeanor, she's inwardly vulnerable, and doesn't see herself as an equal to the other Kings.
- Humongous Mecha: Her Enhanced Armament, "Invincible", is an enormous artillery platform covered in cannons and missile pods, granting her the greatest long-range attack power in the Accelerated World.
- In-Series Nickname: Prefers to be called "Niko".
- Jerk with a Heart of Gold: Although she can be rude, violent and bloodthirsty, she's actually a nicer person than even she would like to admit. She clearly cares about those who are close to her such as her "parent" Cherry Rook and she eventually is able to become friends with Haruyuki and the rest of Nega Nebulus and becomes a very helpful ally.
- Little Miss Badass: One of the youngest players in Brain Burst, but completely blood thirsty, and she reached Level 9 at a much faster pace than other players. She has many incredibly strong long-range attacks.
- Little Miss Snarker: She often points out when Haruyuki is making dumb mistakes due to his inexperience. This is supposed to be somewhat unexpected from a person her age.
- Long-Range Fighter: Scarlet Rain's Enhanced Armament "Invincible" boasts the best long-range arsenal in the Accelerated World, but it renders her unable to move, leaving her vulnerable to close-range attacks. Good luck getting near her, though.
- Macross Missile Massacre: One of her attacks.
- Parental Abandonment: She lives in a home for orphans along with Cherry Rook.
- Personality Powers: Because of her fear of getting hurt, she gained an avatar that can surround itself in impenetrable armor while attacking from a distance. Likewise, her Incarnate abilities fall into the categories of reach and mobility enhancement like Haru.
- Playing with Fire: Her Incarnate attacks manifest in the form of flames.
- Red Baron: In Brain Burst she's called the Immobile Fortress, because she doesn't even have to move to defeat most foes, and she has an enhanced armor that surrounds her that's almost impenetrable.
- Red Eyes, Take Warning: The animegives her red eyes to emphasize her violent and vicious nature.
- Red Is Violent: She wears red, has red hair and eyes, and is pretty vicious.
- Red Oni, Blue Oni: The Hot-Blooded Red to Blood Leopard's cool Blue.
- Relatively Flimsy Excuse: Pretends to be Haruyuki's second cousin, Tomoko Saitou, as part of her failed Batman Gambit to recruit Haruyuki into Prominence and blackmail him into submission with Judgment Blow.
- Shaping Your Attacks: Her Incarnate attack "Radiant Burst" launches fist-shaped blasts of flame.
- She Is the King: She's just a little girl and has already earned the title of the Red King.
- Shoo the Dog: When she fires on Kuroyukihime and threatens Haruyuki, she's trying to get them to go away so that she can deal with Chrome Disaster/Cherry Rook herself.
- Something Only They Would Say: In Accel World vs Sword Art Online, she ends up fighting against an Evil Doppelgänger version of herself. In trying to tell them apart, one Scarlet Rain asks the Burst Linkers for help while the other Scarlet Rain tells them to keep away. Silver Crow and Black Lotus figure out the real Scarlet Rain would have too much pride to ask her rivals so willingly.
- Supreme Chef: played with. She's a novice at most kinds of cooking, but she's very good at baking and sweets. She says outright she picked it up from Pard.
- Tiny Tyrannical Girl: She has the looks of an adorable little girl, but beneath her cute facade there's a dominating and aggressive borderline psycho.
- Token Mini-Moe: The youngest character of the series.
- Transforming Vehicle: Some time before volume 13, she develops a truck-like alternate configuration for Invincible called Dreadnought. In exchange for reduced firepower in this mode it gains the ability to travel at high speed while carrying other avatars on its back, turning it from an "Immobile Fortress" to a "Mobile Stronghold". It does not, however, gain brakes.
- Troubling Unchildlike Behavior: She's revealed to be an Ax-Crazy tyrant who's specialty is Macross Missile Massacre.
- Tsundere: A vicious Type A. She acts like a borderline psychotic tyrant, but she can show a friendly side when she's in a good mood and is willing to help you if you ask nicely enough.
- Unprovoked Pervert Payback: Her dueling Haruyuki essentially amounts to this. Haruyuki points out that she was the one who caused the situation by trying to get in his tub, forcing him to catch her when she fell in, but she's not in any mood to listen.
- Vitriolic Best Buds: With Kuroyukihime. Despite the two having clashing personalities and being heads of rival Legions, they get along quite well when they're not bickering, as Haru notes when he sees them sleeping together.
- Wave Motion Gun: One of her attacks, particularly Heat Blast Saturation.
- Who Wears Short Shorts?: She wears short jean shorts.
- Youthful Freckles: Her face has quite a few.
- Zettai Ryouiki: She wears black thigh-high stockings in her casual attire.
Mihaya Kakei/Blood Leopard
Vice-commander of Prominence and a high level burst linker, who works in real life as a waitress at a cake shop which also doubles as her team's base.
- Absolute Cleavage: not in the show or the books; however, she's the cover girl for LN 14, where she's wearing a skintight red jumpsuit, unzipped to the bottom of her cleavage and showing off some really impressive... assets.
- Affectionate Nickname: She calls Akira, her cousin and her parent, "Aki."
- Aloof Dark-Haired Girl: The tallest girl in the series (so far), aloof and stoic, and has long, dark hair.
- Cat Girl: Her battle avatar simply looks like an armor-plated version of her net avatar; unlike Chiyu she's a humanoid cat rather than a girl with Unusual Ears.
- Energy Absorption: In animal form, Blood Leopard's "Vital Bite" lets her absorb a Duel Avatar's health and killer move gauges.
- Friendly Rivalry: With Sky Raker. Volume 5 shows that she hopes Sky Raker will eventually return to the Accelerated World.
- Giant Poofy Sleeves: In her Meido outfit and school uniform.
- Hair Decorations: Wears a headband.
- Hidden Depths: When Haru talks to Niko about Pard's job at the cake shop in LN 13, Niko lets slip, "Huh? What're you taking about? Pard's that shop's-" before cutting herself off. The only real options for finishing that sentence are 'patissier' (professional level cake and pastry maker) or 'owner'. Unless it was due to inheritance, the first seems a lot more likely, especially since she taught Niko how to bake. It's still highly impressive for a girl who can't be more than 16 or 17.
- Human Cannonball: Her "Bloodshed Cannon" ability, revealed in Volume 15, manifests the barrel of a Leopard tank around Pard to blast her forward. While incredibly powerful it damages her on every use, and can even kill her if she collides with indestructible terrain. On some stages she can abuse it for long-distance travel by repeatedly firing herself through buildings, with the Object Destruction Bonus being enough to recharge her special meter after each use.
- In-Series Nickname: She's called "Pard" in the accelerated world, and "Myah" when visiting the School Festival.
- Insistent Terminology: If you're going to shorten her name, it's Leopard, not Blood, and if you want to go further it's Pard, not Leopa.
- Meido: Dresses and works as one at the Strawberry Palace cafe.
- Panthera Awesome: Her battle avatar's special attack transforms her into one.
- The Quiet One: Rarely speaks a lot, and when she does it's usually very short.
- Red Baron: "Bloody Kitty"
- Red Oni, Blue Oni: The cool Blue to Niko's Hot-Blooded Red. Ironically, she herself is also Red.
- Running on All Fours: Her avatar can change forms into a leopard that runs this way.
- Sailor Fuku: She wears one when she approaches Haru in Volume 7. By comparison, most of the other girls have blazer-style uniforms.
- Spy Catsuit: Wears one with her avatar.
- The Stoic: She rarely shows any emotion and always maintains the same expression on her face.
- Terse Talker: She speaks short, brief sentences and occasionally uses slang.
- Undying Loyalty: To Niko. She identifies Niko as one of two people who are very important to her, the other being Sky Raker.
- Wall Run: One of her abilities in leopard form lets her run on walls by expending her special meter.
- Wrong Context Magic: Why is her avatar a red colour if she fights in melee like a blue? While there does turn out to be an explanation for this, In-Universe most players aren't aware of it and assume she got the colour because she's just that bloodthirsty.
Cherry Rook (5th Chrome Disaster)
Yuniko's friend and "parent" who introduced her to Brain Burst. See the Chrome Disaster section for more details.
Blaze HeartA Level 5 Burst Linker who attacks Nega Nebulus in volume 13, mistakenly believing that Black Lotus has tried to assassinate her King.
- Calling Your Attacks: Wouldn't be unusual for a duel avatar, except that she has to call them into a microphone.
- Contest Winner Cameo: One of the avatar designs submitted for a context.
- Fiery Redhead: Has the personality, and a fiery red-everything.
- Hot-Blooded: Describes her flames as an embodiment of her passion.
- Idol Singer: Evokes this image with her microphone and distinctive poses, specifically being modeled on Miku Hatsune.
- Musical Assassin: Her "Searing Note" attack launches musical notes that explode into flames.
- Wreathed in Flames: Her "Burning Heart" move sets her on fire, boosting her melee attack power but causing her to take damage over time.
- Zettai Ryouiki: Grade S.
Peach ParasolA Level 4 Burst Linker who assists Blaze Heart in her attack.
- Contest Winner Cameo: One of the avatar designs submitted for a context.
- Parasol of Pain: It doubles as a gun and a shield.
Ochre PrisonA Burst Linker who assists Blaze Heart in her attack.
The Yellow King, who kept with him a shard of the defeated fourth Chrome Disaster.
- Combat Pragmatist: His first encounter with Haru and co, involves gaining up on them with his minions and guilt tripping Black Lotus with imagery showing how she killed Red Rider. He also retreats when Cherry Rook shows up and has his forces retreat when confronted with a disadvantage
- Hoist by His Own Petard: Nearly was done in by Cherry Rook, the player he had injected with the shard of the 4th Chrome Disaster. He uses his illusions powers to escape
- Karma Houdini: Despite causing the 5th Chrome Disaster, he has yet to get any comeuppance for this, even denying this happened.
- In the Back: One of his illusions get stabbed from behind by Cherry Rook.
- Lean and Mean: His avatar is very lean and lanky with long arms and legs.
- Manipulative Bastard: Yellow Radio manipulated Cherry Rook to become the fifth Chrome Disaster so that he would attack his Legion, so he could attack the Red King for violating the non-aggression treaty.
- Master of Illusion: He has abilities that cause illusions to distract his enemies. This is common for yellow colored avatars.
- Monster Clown: The design and appearance of his avatar.
- Red Baron: Known by the title "Radioactive Disturber".
- Smug Snake: He expected Kuroyuki to stay down after reliving her guilt, and is shocked when she gets up. His overall faked politeness gives off this vibe as well.
A member of Crypto Cosmic Circus who participates in the attack on Scarlet Rain.
- Boisterous Weakling: Dramatically announces "It seems the great Cyan Pile was all talk. Remember this, the name of the one who killed you is Sax-", only for Pile to blow his head off before he can finish.
- Humongous Mecha: A huge, blocky avatar resembling a construction vehicle.
- Multi-Armed and Dangerous: Has multiple cranelike arms emerging from his back.
- This Is a Drill: One of his crane arms ends in a conical drill.
An avatar styled after a young female jester balancing on a ball.
The Green King, who has been around since the early days of the game and has seen four Chrome Disasters fall. Said to have the greatest "data pressure" of any of the Kings.
- Attack Reflector: One of his abilities, Double Payback, allows him to reflect the damage he receives.
- Expy: A prominent guild leader with a unique cross-shaped shield, famous for being a Stone Wall whose health has never fallen into the yellow? Sounds a lot like Heathcliff from the author's earlier work Sword Art Online, who made an identical boast. On learning how much Grandee knows about the origins of Brain Burst and how he actively maintains its economy, Haru even asks him if he's the creator of the game in disguise much like how Heathcliff was secretly the creator of Sword Art Online. This similarity is lampshaded in the game Accel World Vs Sword Art Online if Green Grandee fights Kirito.
- Famed In-Story: As one of the veteran players of the game, he was known for extensive Solo Character Runs, accruing lots of Burst Points in the Unlimited Natural Field, and he can only lose on timed duels.
- Luckily, My Shield Will Protect Me: He uses his enhanced armament The Strife to protect himself and avoid damage.
- Named Weapons: His shield "The Strife", one of the Seven Arcs.
- Painting the Frost on Windows: Why does the Unlimited Neutral Field have Piñata Enemies that don't just grant Burst Points for defeating them, but drop cards containing extra points? It's not a game mechanic - Green Grandee works tirelessly to farm points from strong Enemies and feed them to weaker ones, hoping that it will allow players to survive just by hunting them.
- The Quiet One: Rarely speaks and often described as a silent person. He's so patient that he once waited in a single spot for three months of in-game time, hoping for a random event that would allow him to strike a blow at the Acceleration Research Society.
- Red Baron: Known by the title "The Invulnerable" for having the highest defense in Brain Burst.
- Stone Wall: As both the purest and highest-level example of the defense-focused green avatars, armed with both defense-enhancing Incarnate techniques and the strongest equippable shield in the game, it's very hard to damage him. The most a lot of players can do is Scratch Damage.
- Wham Line: His answer for his reason behind hunting enemies, buying point cards and feeding them to enemies, enabling players to earn points without having to duel.Grande: It was all to stop Brain Burst 2039- also known as Trial Number Two- from ending in vain.
- World Tree: Due to his solemn, immobile nature, and how he seeds Enemies with item drops to prevent players from running out of points, he's referred to as "the tree that supports the world".
The third seat of Great Wall's "Six Armors" - a boxer-themed Level 7 avatar who first appears in volume 9.
- Boxing Battler: His avatar's main theme.
- I Know Mortal Kombat: Inverted - his experience with actual boxing translates directly into the game.
- Lightning Bruiser: His iron body makes him very durable, and he has the skill to move and attack at extreme speed.
- Rapid-Fire Fisticuffs: Has an Incarnate System ability which greatly increases his punching speed, mastered to such a high level that he doesn't need to call a name to activate it.
- Reflexive Response: While his fighting instincts are formidable because they were shaped by boxing they can be thrown off by situations that aren't possible in a match (such as an opponent teleporting behind him and striking his back).
- Rocket Punch: His "Rocket Straight", which Haru notes as unusual for someone who claims to focus on raw skill over gimmicks. Reportedly an ability he developed as a counter for Sky Raker's Not Quite Flight.
- Square Race, Round Class: Inverted - a trained boxer in the real world, his boxer-themed avatar allows him to bring his skills directly into the game, placing it in a rare category known as "Perfect Match".
- Super Toughness: Iron lies to the far right of the metallic colour spectrum, giving him great defense against physical attacks but little against status conditions.
- Weak, but Skilled: Trained to defeat any new instances of Chrome Disaster by focusing only on his fundamentals, knowing that the Armor would be a sloppy fighter due to its nature as The Berserker and lacking experience in the powers of its past hosts. This proves so successful against a Disasterized Haru that the Armor is forced to loosen its control on him just to survive.
Rinta Kasukabe(?)/Ash Roller
A player with a motorcycle for Enhancement Armament and Silver Crow's first opponent.
- Ambiguous Situation: Whether or not it's Rin's brother's soul controlling the Ash Roller character or just a copy of it, is unknown.
- Badass Biker: Rides a western motorbike, which his entire fighting strategy relies on. It is called the Night Rocker.
- Big Brother Instinct: He's highly protective of Rin, to the point at which when he gets infected by the ISS Kit, he'd be willing to be erased from Brain Burst entirely for the sake of his sister's well-being.
- Crazy-Prepared: Invested in the ability to drive up walls after defeating Silver Crow the first time in case it was necessary. Much to Ash Roller's surprise, it was as necessary as the soon as their rematch.
- Demonic Possession: His Enhanced Armament gets infected by an ISS kit in Volume 13. Since it's impossible to remove the kit the standard way, Ash wants someone to knock him off Brain Burst for Rin's sake.
- Friendly Enemy: Despite being a member of a rival Legion, he's on fairly good terms with Haru and Sky Raker.
- Giving Someone the Pointer Finger: Ash Roller's other favorite gesture is Flipping the Bird.
- Gratuitous English: He loves spouting random English phrases midsentence. Most notably his Catchphrase(s): "LUCKY!", "MEGA LUCKY!", "GIGA LUCKY!", etc.
- Hell-Bent for Leather: Combined with Spikes of Villainy, skulls, and a Cool Bike... Ash would fit in perfectly on a Heavy Metal album cover.
- Jerk with a Heart of Gold: It's true he's a tough, crude biker who loves to fight and swear, but he's also a noble and friendly individual to those he respects. He's even willing to stop a match to encourage and help out his troubled rival or call out his duel partner for his dishonorable tactics and dickish behavior.
- Large Ham: He yells just about everything at the top of his lungs.
- Leitmotif: Monster Machine
- Motorcycle on the Coast Road: With Silver Crow in the second opening.
- My Sister Is Off-Limits!: When Haru calls him by Rin's first name, Ash Roller gets furious at the possibility of Haru being in a relationship with Rin.
- Pet the Dog: When Haru is too depressed to fight after losing his wings, he actually stops the match to try to encourage him, and later takes him to meet Sky Raker.
- Rebel Relaxation: Up a Cool Bike, no less.
- The Rival: To Silver Crow.
- Sibling Yin-Yang: He and his sister are almost polar opposites in terms of personality and temperament.
- Sir Swears-a-Lot: Sometimes Played for Laughs with a Sound-Effect Bleep.
- Skull for a Head: His avatar has a skull for a face, possibly inspired by Ghost Rider. In later books he sometimes removes his helmet when he needs to talk seriously, and without it he's described as looking surprisingly young and bookish.
- Wall Crawl: The bike can run up walls.
- You Called Me "X"; It Must Be Serious: He calls Haruyuki by his real name when asking him to be friends with his sister so that she'll have good memories outside the Accelerated World once Ash Roller is gone.
A Burst Linker and the child of Fuuko Kurasaki. When Rin downloaded Brain Burst, it was on her brother's Neuro Linker instead of her own. She is a special case; although she is technically the owner of Ash Roller, the one operating it is her brother who is in a coma.
- Early-Bird Cameo: She appears near the end of the anime's first season, and in the second OVA, where she's quite nervous around Haruyukinote , and seems acquainted with Rin.
- Ill Girl: After Ash Roller gets infected by the ISS Kit, Rin seems somewhat unwell in real life.
- Samus Is a Girl: Played with. Rin is technically the real identity of Ash Roller, but her Duel Avatar is controlled by the soul or copy of her brother's mind, who is in a coma.
- Shrinking Violet: She's a shy girl with self-esteem problems.
- Sibling Yin-Yang: Her brother's a loud and brash Jerk With Aheart Of Gold, while she's a shy, timid Nice Girl.
- Verbal Tic: She often. Speaks. In short. Sentences.
- Walking Spoiler: She's very difficult to talk about without spoiling Ash Roller's true nature.
- Wham Line: "I'm. Ash. Roller."
- Vocal Dissonance: Haru describes Suntan as a "midsize avatar with [a] solidly built silhouette", and is surprised to hear her speak with a female voice. Oddly, she's depicted in later art as an obvious Anime Chinese Girl.
- The Stoic: Described as having a similar air about her to Aqua Current.
- Badass Baritone: Described as both speaking in a baritone voice, and being an obvious combat veteran.
- In-Universe Nickname: Iron Pound calls him "Viri".
Graphite EdgeFirst seat of Great Wall's Six Armors, said to be strong enough to curbstomp Viridian Decurion and even fight the Green King himself to a draw. Had never been seen by the lower-ranking Armors until the events of volume 17. Actually Graphite Edge, a former member of Nega Nebulus. See their section for more details.
The Blue King, and one of the first players of Brain Burst along with his best friend, Red Rider.
- Cool Sword: "The Impulse", one of Brain Burst's Seven Arcs.
- Famed In-Story: Revered for defeating a Legendary Beast all by himself, whereas entire teams can barely make it past lesser bosses.
- Heterosexual Life-Partners: With the late Red Rider.
- Named Weapons: His sword: The Impulse.
- Pet the Dog: Refuses to use Judgment Blow on Cyan Pile after the latter defects to Nega Nebulus.
- Red Baron: Known by the tiles "Vanquish", "The Holy Sword" and "Legend Slayer".
- Shoulders of Doom: So huge they can be used as shields. In fact, that's probably what their purpose is.
Cobalt Blade and Manganese Blade
A pair of Level 7 sword fighters and subordinates of Blue Knight.
The Purple King and lover of Red Rider. Leader of the Purple Legion.
- Clingy Jealous Girl: By all accounts she is very much this, never once liking the way Red Rider and Black Lotus spoke and interacted.
- Named Weapons: Her staff "The Tempest", one of Brain Burst's Seven Arcs.
- Red Baron: Earned the nickname Empress Voltage.
- She Is the King: The third female King of the Accelerated World.
- Shock and Awe: Her abilities appear to based around electricity and she seems to have an obsession with recruiting other electric users into her legion.
- Staff of Authority: Her enhanced armament, The Tempest.
- Teeth-Clenched Teamwork: While her Legion and Nega Nebulus have a common enemy in the Acceleration Research Society, Purple Thorn frequently insults, threatens or belittles Kuroyukihime.
Purple Thorn's aide.
- Cool Shades: One of her avatar's few obviously robotic traits is a translucent visor which evokes a pair of wraparound shades.
- Dressed Like a Dominatrix: Unusual for looking like an actual outfit her avatar is wearing, rather than part of its body.
- Non-Standard Character Design: Duel avatars with hair or visible mouths are rare but not unheard of. Humanlike skin and hair colours, with the avatar's signature colour limited to its "clothing"? Much more unusual.
- Number Two: To Purple Thorn.
- Whip It Good: The "vine" of her name.
The White King and legion master of Oscillatory Universe.
- Big Bad: She is the head of the Acceleration Research Society — the one that included the likes of Seiji Noumi.
- Broken Pedestal: To Kuroyukihime. It's indicated that she once held her in high regard, and they had a close relationship that facilitated White Cosmos becoming Kuroyukihime's parent, but after being manipulated and betrayed, Kuroyukihime is incredibly bitter.
- Cain and Abel: She's Kuroyukihime's older sister and her worst enemy who tricked her into beheading Red Rider.
- Cool Chair: Her design in spinoffs depicts her with an Enhanced Armament in the form of a floating throne which carries her around.
- Didn't See That Coming: Her plan to manipulate Kuroyukihime into killing Red Rider goes off without a hitch until Red Rider's gun ends up in Kuroyukihime's inventory, causing her to realize that his gift was harmless and that she'd been tricked.
- Good Powers, Bad People: One of the very few healers in Brain Burst. Her ability "Resurrection by Compassion" makes dead avatars come back to life... whether they want to or not. She uses this for torture.
- Healing Factor: She's one of the three healing types in Brain Burst, apart from Chiyu and an unnamed third person.
- Invisible to Normals: One of her special abilities allows her to become invisible to everybody except for other Level 9 players.
- Light Is Not Good: Despite being a white colored avatar, she is not a person you would call good. Given that she is the head of the Acceleration Research Society, and contributed to the death of Saffron Blossom resurrecting her over and over as she was killed and devoured.
- Manipulative Bitch: Kuroyukihime suspects that White Cosmos has been manipulating her for years, and reveals that she didn't want Haruyuki to meet (or hear too much about) her out of fear that White Cosmos would also manipulate him.
- Marth Debuted in "Smash Bros.": While her duel avatar is obscured in the main story, it received a design in the videogame Peak of Acceleration, which was reused in Accel World Vs Sword Art Online.
- The Medic: One of the three known healer-type avatars in the Accelerated World.
- Necromancer: She has the ability to reanimate defeated Burst Linker avatars.
- Phosphor-Essence: On the rare occasions her avatar is seen, it's wrapped in a veil of light that obscures its true shape.
- Red Baron: Known by the title "Transient Eternity".
- She Is the King: One of the female Kings of the Accelerated World.
- Virtual Ghost: Her ability to resurrect dead Duel Avatars works even when the player behind them is no longer capable of returning to the game.
- Walking Spoiler: It's impossible to mention that she's anything other than the White King without spoiling a great deal about Kuroyukihime's backstory.
- Wounded Gazelle Gambit: Upon realizing that her sister manipulated her, Kuroyukihime attacked White Cosmos in real life with a box cutter, injuring her. White Cosmos then decided to make the injury look worse than it actually was, resulting in Kuroyukihime getting thrown out of the house.
The White King's representative during the Kings' meetings.
- In the Hood: His head is a "tower" resembling a capirote, giving the impression of a priest or someone hiding their appearance.
- Lean and Mean: While his lower body hasn't been shown, he has an elongated head and slender clawed arms.
- Mouth of Sauron: As the White King herself is never seen, Ivory Tower is authorised to speak on her behalf.
- The Nondescript: His "data pressure" is lower than the other Kings' attendants, and even his voice is described as "featureless, communicating nothing but the fact that he was probably male". Strangely, according to Metatron the actual amount of data in his avatar is very high, implying that he has some way of concealing his presence.
- Unfortunate Character Design: Probably unintentional, but he looks a lot like a member of The Klan. Being the representative of the White Legion doesn't help.
Vice-President Black Vise
The rather polite, well-spoken Vice-President of Acceleration Research Group, where Noumi and Sulfur Pot belong to, and a Level 8 Burst Linker. He helped Noumi set up an ambush for Haruyuki and Taku to catch them off-guard during the sudden-death battle between them.
- Affably Evil: He's very polite at all times, even when talking with his foes.
- Berserk Button: For Chrome Disaster, being one of the avatars responsible for his suffering.
- Bullet Time: He's the only Duel Avatar who can speed up his own time in the Accelerated World, so he can make himself immune to the Year Inside, Hour Outside effect of the Accelerated World.
- Casting a Shadow: Has the ability to hide inside shadows to travel at high speed or tail other avatars in secret. He can even carry other avatars and objects while doing this. Volume 15 reveals that he has also created a Portal Network of "shadow corridors" which members of the ARS use to travel to and from their base.
- Detachment Combat: Some of his trap skills revolve around using detached body parts to attack.
- Know When to Fold 'Em: Retreats once he realizes that he's fighting a losing battle (and he is on a stalemate with Kuroyukihime), vowing never to directly tangle with the Black King again while leaving Noumi at Haruyuki's mercy.
- Lack of Empathy: Black Vise clearly shows signs of this as during the execution of Saffron Blossom.
- The Magnificent: His alias of "Black Vise" is interpreted by the protagonists as a way of declaring himself equal to the Kings of Pure Color, as well as a slight against that color's rightful owner Black Lotus.
- Noble Demon: In contrast with Noumi. He even shows due respect to Kuroyukihime for her skill as well as being the Black King, as well as Haruyuki for actually managing to elude his death trap.
- One Steve Limit: An odd case in that he's supposedly the second black duel avatar. It's unclear whether "Black Vise" is his official name.
- Punch-Clock Villain: Black Vise is described as sounding like a businessman instead of a fighter.
- Shout-Out Theme Naming: Like the real black king Black Lotus, he shares his name with a banned Magic: The Gathering card, albeit not one that's part of the iconic "Power Nine". This is also a major hint to his true identity: "Black Vise" and "Ivory Tower" have identical costs and exact opposite effects.
- Vocal Dissonance: In-Universe, Chrome Falcon suspects that he sounds a good deal older than those who have been wearing Neurolinkers since they were born.
- Voluntary Shapeshifting: Among his abilities, he can arrange his panels to imitate the shape and voices of other avatars. This disguise is imperfect, however, and once he steps out of the shadows it's obvious that his body is still flat. This is a hint that his Shapeshifter Default Form is also fake.
- The Walls Are Closing In: The usual application of his ability is trap people by pressing black blocks against them.
Seiji Noumi/Dusk Taker
A first-year entrant to Umesato (with Haru, Chiyu, and Taku moving onto the second year). After soundly defeating Taku in a kendo exhibition match, Haruyuki and gang discover that he is a Burst Linker with some way of hiding his name on the matching list, meaning he can only be challenged through direct cable matches. His special ability is to steal special attacks, equipment, and skills from other Burst Linkers. The effect is also permanent unless he voluntarily reverses the effect as opposed to just lasting for the duration of a match.
- Achilles' Heel: In addition to the limit to the number of powers he could use, he cannot steal Incarnate skills (because it comes from the Burst Linker's own will and is not predetermined by the system) and abilities not related to his own traumas. Thus, he can only steal abilities from Duel Avatars whose abilities are not specific to their own traumas.
- Arc Villain: He is the main antagonist of his eponymous arc.
- Bad Powers, Bad People: He doesn't just copy abilities, he steals them. And then blackmails his opponents if they want them back.
- Big Brother Bully: Has one. The main reason he is such an asshole.
- Bitch in Sheep's Clothing: Appears as a nice guy to most people. But he's actually a very Smug Snake.
- The Bus Came Back: He returns in Volume 13, when the kendo club performs at the school festival. It soon turns out that Wolfram Cerberus III has Nomi's memories and personality
- Combat Tentacles: The stolen power he usually equips to his left arm.
- Dark and Troubled Past: Was evidently abused by his brother, until he decided to kill him in the game.
- Dirty Coward: Grovels at Haruyuki, Kuroyukihime, Chiyuri and Takumu's feet begging for what remains of his BP once it became clear that Chiyuri has been working against him all along, Haruyuki has turned the tables on him, and that the rest of ARS left him on his own. Haruyuki would have none of it.
- The Dog Bites Back: After becoming strong enough and gaining the opportunity, Noumi kills his abusive brother repeatedly, and takes great pleasure in it.
- Evil Counterpart:
- Apart from colour scheme, Dusk Taker and Silver Crow with their special abilities inactive look very similar (the main difference is Taker having bulkier neck/shoulder armor). Taken further when Taker steals Crow's wings. He also cheats his way through his grades through the use of Brain Burst, much like Taku did before his HeelFace Turn. Taku even figures out the exact moment Noumi accelerates to cheat on a test in order to challenge him to a duel.
- One can argue he's also what Haru could've been like if life were to pushed him too far. Both have suffered from bullying in the past. While Haru is fat and stubby, Nomi is Lean and Mean. Whereas Haru worked his way through Brain Burst with sheer hard work, Nomi uses deceit and manipulation to get his way.
- Faceless Eye: The head of his Duel Avatar looks like this.
- Faux Affably Evil: He exhibits a superficial level of politeness to his enemies, addressing them as his senpais, but when the conversation turns to Brain Burst, he shows his mocking and condescending side.
- Fire-Breathing Weapon: One of the stolen powers he can equip to his right arm; long-ranged and strong enough to melt rock.
- Freudian Excuse: He was bullied by his brother, and had everything taken away from him.
- Game-Breaker: Considers himself one of these In-Universe after Dust Taker starts combining Silver Crow's flight with powerful ranged weapons.
- Good Wings, Evil Wings: After stealing Silver Crow's aviation ability his wings are considerably more demonic looking.
- Hate Sink: By all indications, he's a low-level member of the Acceleration Research Society, but he's one of the most unpleasant and despicable characters in the series. Considering what a Jerkass Smug Snake he is, even his Freudian Excuse is still not enough to move the fanbase, and considering that he gloats about it, it doesn't inspire much in Haruyuki, either. The most sympathy Haru has for him is suggesting that they might have been friends if they'd met as normal Burst Linkers, but Noumi scoffs at the suggestion.
- HeelFace Turn: After he lost his memories he became nice and cheerful.
- Healing Factor: One of his abilities that he stole.
- Keet: After he loses his memories of Brain Burst.
- Mind Wipe: Lost all his memories of Burst Link after it was forcibly removed from him after losing to Haruyuki, proving Kuroyukihime's theory that uninstalling the program will also erase its user's memories of playing it.
- Obviously Evil: His duel avatar. Averts this completely in real life.
- Power Parasite: Dusk Taker has the Demonic Commandeer ability which permanently steals abilities, techniques and equipment from other Burst Linkers to use for himself. While there is a limit to how many he can use, he can still use multiple ones at the same time.
- Shapeshifter Mashup: Downplayed. When using multiple stolen powers at once (and their corresponding body parts) his avatar can look quite bizarre, though it remains mostly humanoid.
- Skull for a Head: Underneath the visor, his avatar's head is quite skull-like; it becomes briefly visible when he uses Demonic Commandeer.
- Smug Snake: Very smug and always looking down on people treating them like insects. As a result, he doesn't even consider the possibility of Haru turning the tables on him or Chiyu betraying him.
- Stop Having Fun Guy: Noumi sees Brain Burst and Acceleration solely as a means to advance himself in the real world. He openly mocks any sense of friendship and camaraderie fostered by the game and refuses to refer to himself by the "childish moniker Burst Linker. And he has no problem looking down on anyone who does not share his point of view.
- Took a Level in Kindness: After losing his Brain Burst upon losing, rather than being all smug when meeting Haru, he acts nice and cheerful. This is the result of losing all his memories involving the Brain Burst.
- Troubled Abuser: Treats others the way his older brother treated him. It's used to make him seem petty rather than sympathetic.
- Villainous Breakdown: Once it became clear that all his plans are rapidly falling apart, even more so once he realized that Chiyuri only played him so she can restore Haruyuki's wings, finally descending into a whimpering mess begging Haruyuki to spare his last BP.
A Burst Linker who dives into Okinawa while being in Tokyo using a backdoor program.
- Fluffy Tamer: Loses this ability upon defeat. Kuroyuki eventually takes said ability (legally) as a gift from the Okinawa players.
- Playing with Fire: In a rather different way, the primary ability that he is seen using is Charcoal Smoke which releases gun powder into the air that can be ignited and catch fire. Which he used in combination with Nick.
- Smug Snake: Overconfident to a fault, with absolute certainty in his belief that he and Nick are the ultimate partners.
A Legendary Enemy of the Unlimited Neutral Field, he is controlled by Sulfur Pot.
- Fluffy the Terrible: Is given the name Nick by Sulfur Pot.
- Meaningful Name: In Norse mythology, Níðhöggr (Malice Striker, often anglicized Nidhogg) is a dragon who gnaws at a root of the World Tree, Yggdrasil.
- Pet the Dog: When he is freed from his control he did not try to attack Black Lotus, Coral Merrow, and Lagoon Dolphin even after attacking Sulfur Pot.
A Level 6 trap-oriented Burst Linker.
- Arc Villain: After making a brief appearance in the Dusk Taker arc, he becomes the primary threat to the heroes in The Bridge Floating in Starlight arc.
- Berserk Button: All of his actions are taken under orders. Do not imply that he's doing anything just to amuse himself.
- Deadly Disc: His Wheel Saw ability sends a deadly rapidly rotating saw blade flying at his foe.
- Just Think of the Potential: Going a step further than Noumi, he doesn't even enjoy the game aspects of Brain Burst, and is enraged by the sheer idiocy of people who would use such an incredibly powerful "lifehack tool" just to have fun.
- Make Them Rot: His use of the Incarnate System causes rapid corrosion of his targets' defenses. It doesn't work on corrosion-resistant metals like stainless steel.
- Touch of Death: His second-order Incarnate ability, "Rust Touch".
- Trap Master: His razor tripwires are designed to trap close-range opponents so he can dispatch them.
- Verbal Tic: When he begins a sentence with a verb, he will often say it as its own sentence first (e.g. "Regret. Regret that you...")
- Walking Wasteland: The effect of his Incarnate ability, "Rust Order". Very powerful (implied to be boosted through illegal use of a Brain Implant Chip) but takes a long time to prepare.
A Level 6 Burst Linker who distributes "ISS Kits" - parasitic items that grant their user powers from the Incarnate System at the cost of their sanity.
- The Aggressive Drug Dealer: In addition to offering her Kits to Burst Linkers in search of power, she and her clients also attempt to force the Kits on others.
- Arc Villain: She and her ISS Kits are considered a serious threat for a good chunk of the story, though Scissor herself isn't always in focus since the Kings are more interested in finding the source of the Kits and destroying it.
- Assimilation Plot: Downplayed. Wants to use the ISS Kits to remove any distinction between duel avatars, thereby making everyone equal. Nega Nebulus want to stop her not only because the Kit is screwing with Burst Linkers' minds, but because a Brain Burst where combat consists only of identical avatars trading Dark Shots and Dark Blows back and forth would be a dreadfully boring one.
- Bandage Babe: Her entire body is wrapped in magenta bandages, leaving only her lower face uncovered.
- Get Rich Quick Scheme: The ISS Kits have elements of a pyramid scheme, making their host more powerful the more they spread its spawn to others.
- Getting High on Their Own Supply: Hidden under her bandages, she's infected by an ISS Kit herself. Justified in that the Kits reproduce by budding - her supply consists of her own Kit's "children".
- Hive Queen: Once the offshoots of her ISS Kit are fully integrated with their hosts, they become little more than mindless drones under her command.
- Master of All: The Kit's abilities include two powerful attacks, one melee and one ranged, which turn any avatar into an all-rounder or allow them to shore up their weaknesses. Due to being based on the Incarnate System, these attacks are also difficult to counter for anyone who can't use Incarnate abilities themselves.
- Psycho Serum: The Kit allows its user to enter a powerful "IS Mode" but steadily eats away at their sanity, even while not using Brain Burst.
- Shear Menace: Her main weapon is a pair of scissors which can cut from a distance, though it's normally kept split into two blades.
- Strong, but Unskilled: Most of her infectees forget their avatar's normal abilities and rely entirely on the Kit's "Dark Shot" and "Dark Blow" attacks. While powerful, their lack of variety means that the heroes quickly get used to dealing with them. Scissor herself is an aversion, both retaining all her original skills and mastering her Kit to the point where she can use its attacks without an activation command.
- The Symbiote: Once a duel avatar equips an ISS Kit, it fuses with them and manifests as a blood-red eye somewhere on their body. Separating the two afterwards is difficult, and can require different methods depending on the victim.
- Unwitting Pawn: Appears to have been merely set in motion by the ARS rather than being an actual member of the organization.
A duel avatar shaped like a giant avocado with spindly arms and legs. Was abandoned by his "parent" for his ridiculous appearance, and nearly stripped of all his points until Magenta Scissor took him in.
- Alliterative Name: Avocado Avoider.
- Cephalothorax: Has a mouth on his torso, but no eyes or head.
- The Dragon: To Magenta Scissor.
- Fighting Clown: Despite his bizarre appearance, he's a useful ally in a fight.
- The Power of the Void: What the "Avoider" in his name really means.
- The Quiet One: Retains his personality despite the influence of the ISS kit, but speaks mostly in sentence fragments.
- Stone Wall: His avocado flesh reforms when struck by physical attacks. Even if his main body is completely destroyed, his core (an avocado pit) can sprout limbs and escape.
- Swallowed Whole: His primary means of attack is to hold enemies in his mouth and dissolve them.
- Time Stands Still: Things inside his stomach do not experience the flow of time, though they still take damage.
A Level 1 Burst Linker with a triple-personality problem.
- Anti-Villain: The least malevolent of the ARS Linkers, to the point that he actually asked Haruyuki to help him deal with his personality split, and actually defending him from Argon Array.
- Death Seeker: When Cerberus sees Silver Crow again in the Unlimited Neural Field, he does so in the hopes that Crow will kill him and remove him from Brain Burst for good.
- Dungeon Bypass: His strength and durability allow him to create shortcuts by charging through walls.
- Game-Breaker: In-universe example. Wolfram Cerberus has three different abilities, one per personality. The main head has <<Physical Immunity>> which renders him impervious to direct physical attacks of any kind. The second head has <<Wolf Down>> which allows it to temporarily copy someone's ability upon chomping a part of their body. The third head has Dusk Taker's <<Demonic Commandeer>>. Best of all is, he has this at level 1.
- Lightning Bruiser: Having a body of wolfram (i.e. tungsten), he's sturdy enough to punch through walls like paper, yet agile enough to knock Crow out of the air. Being on the far-right of the metallic colour spectrum, though, his defence against energy-based attacks is less than amazing.
- Meaningful Name: He has three split personalities, much like the mythological Cerberus has three heads.
- Multiple Head Case: Has a helmet shaped like a wolf's head, and similar armour on each shoulder. When the visor on his main head closes, one of his shoulders can open to reveal a different face with its own personality.
- No-Sell: While Physical Immunity is active, he cannot be harmed by direct physical attacks. Energy attacks still work, however, and he still suffers collision damage if thrown.
- Not So Different: He ends up doing to Silver Crow what Silver Crow did to Cyan Pile- beating a higher level player by virtue of a special and almost illegal ability.
- Power Copying: His second head's ability "Wolf Down" lets it bite off a piece of another avatar, both dealing damage and granting him a copy of that avatar's powers for a short time.
- Split Personality: Three, in fact.
- Super Toughness: His body is composed of tungsten and tungsten carbide, making it almost as strong as diamond. And that's before he activates his Physical Immunity ability.
- Sure, Why Not?: When a contest for fan-designed duel avatars was held, one of the entries was "Tungsten Wolfram" - an avatar almost identical to Kawahara's existing plans for Wolfram Cerberus. Tungsten's creator was awarded a special "Miracle Prize", and some of its abilities were incorporated into Cerberus.
- Suspiciously Similar Substitute: Veteran burst linkers note that his jagged metal body, personality and rapid rise to fame make him alarmingly similar to Magnesium Drake, who would go on to become the second Chrome Disaster.
A Level 8 Burst Linker with the special ability to scan her enemies' stats. "Parent" of Wolfram Cerberus.
- Blinded by the Light: Her special attack "Razzle Dazzle".
- Enemy Scan: Her unique ability.
- Eye Beams: From both her normal eyes and the ones in her hat.
- Faux Affably Evil: She has a friendly, cheerful demeanor that goes in hand with her often sadistic nature.
- Multi-Directional Barrage: Her Incarnate technique "Infinite Array" creates Extra Eyes all over her body, upgrading her normal Eye Beams into a shockingly fast and powerful Beam Spam.
- Nice Hat: A bulbous one containing two headlamps. Haru initially isn't sure whether or not it's part of her head.
- Psycho Psychologist: Came up with the "Mental Scar-Shell" theory to explain why some avatars are granted metallic colours, as well as a way to trigger this effect in new Burst Linkers deliberately.
The Armor of CatastropheA glitched item properly known as "The Disaster", which takes over Burst Linkers and corrupts them into an entity called Chrome Disaster.
- All Your Powers Combined: Retains imprints of the powers of all its past hosts, though only one user was capable of bonding with the armor deeply enough to use them.
- Armor of Invincibility: The armor "The Destiny" originally granted its wearer incredible defensive abilities, though in its corrupted state its stats have shifted to focus more on attack power.
- Clingy Costume: Infects the mind of its wearer with Chrome Falcon's hatred, and is almost impossible to separate from them. Even if a Disaster retains enough control that they can take the armor off, some of it will remain bonded to them, altering their base appearance to incorporate some of the armor's Spikes of Villainy.
- Demon of Human Origin: Was originally a normal duel avatar, until he went insane and fused together with two high-level items through incredibly strong negative Incarnation.
- Enemy Scan: The sword Star Caster is capable of analysing enemy attacks, determining their properties, threat level and probable trajectory (the latter giving its wielder a form of Spider-Sense).
- Item Drop Mechanic: Can survive the death of its host by adding itself to the inventory of one of the duel avatars that killed it.
- Legacy Character: Each user of the armor takes up the name "Chrome Disaster".
- Life Drain: The armor is capable of absorbing health from enemies; it's unclear whether or not it had this property when it was The Destiny.
- No-Sell: Being made of chrome, it's unaffected by corrosion attacks.
- Portmanteau: Its name as an item, "The Disaster", is a combination of the names of its components - "The Destiny" and "Star Caster".
- Red Is Violent: Wields a red weapon, and has manifested red eyes for some of its wearers. The "Over Rays" generated when it uses the Incarnate System are also red.
- Shout-Out: Has a number of similarities to the Venom symbiote, including its "Future Prediction Calculation" ability, and its introduction where it's bonded to someone who swings between skyscrapers on grappling hooks. Most notably, the two potential methods for separating it from its host involve fire and the sound of a bell, correlating to Venom's heat/sound weaknesses and how Spider-Man originally rid himself of it by exposing himself to loud church bells.
- Superpowered Evil Side: Capable of communicating with its host and spurring on their negative emotions, even when they're not playing Brain Burst.
- You Kill It, You Bought It: Rewards itself as loot to anyone who kills the current Chrome Disaster. Unfortunately, defeating a Chrome Disaster usually requires a large party, and the item could appear in the inventory of anyone who participated in the battle (who may choose to simply lie about it). And even when no one receives the item, it can bypass the inventory system and embed itself in an avatar directly.
Chrome Falcon (1st Chrome Disaster)An Originator in Brain Burst, Chrome Falcon is the first Chrome Disaster, responsible for creating the Disaster Armor after his partner and lover had Brain Burst permanently uninstalled.
- Despair Event Horizon: He became the first Chrome Disaster due to reaching this when his lover, Saffron Blossom, was deleted from the game.
- Dying Curse: He leaves one to those who would seek out the Disaster Armor, doubling as a "The Reason You Suck" Speech to the ruthlessly competitive players he hated.I'll leave my rage and Blossom's suffering to this armor, to the Disaster. The next time someone craves power and puts it on, they will become something that attacks all Burst Linkers, destroys them, devours them. They will eat them and steal their powers and become infinitely strong. Until they are the last one. Until the end when only one remains in the wasteland of the infinitely vast Accelerated World.Because that is the true nature of your desire.I curse this world. I defile it. Even if I disappear temporarily here, my rage and hatred will come back to life any number of times.
- Flash Step: His signature ability, "Flash Blink".
- Fragile Speedster: Chrome Falcon's potential lies entirely in a single ability, whereas otherwise, his Duel Avatar is very weak. In this case, said ability is a pseudo-teleport/Flash Step ability.
- Love Makes You Evil: It was his love for Saffron Blossom that motivated him so strongly. When he lost her, the results... were not pretty.
- Posthumous Character: Has long since been deleted from Accel World, but his effects (specifically the Disaster Armor) are still felt years afterwards.
- Shadow Archetype: A Lethal Joke Character Duel Avatar with a metal color and named after a bird, and all of its potential put in a single powerful ability. Driven to protect a girl he loves, yet believes is completely out of his league. Abandoned by his parents. Low self-esteem and very timid, but capable of great determination. Chrome Falcon serves as a very disturbing look into what could happen to Haru if he ever lost Kuroyukihime.
- Troubling Unchildlike Behavior: What Chrome Falcon did and became is a lot more disturbing when you find out he was eight years old. Justified with the Accelerated World's Year Inside, Hour Outside aspects (he claims that he's spent five years inside it and feels out of place among other kids his age), but still.
Saffron BlossomAn Originator in Brain Burst, Saffron Blossom was the partner and lover of Chrome Falcon. When he became Chrome Disaster, her mind was trapped in its sword, unable to communicate with him.
- Armor of Invincibility: Her armor "The Destiny", one of the Seven Arcs, boasts the highest defence of any equippable item in the game and is implied to let her absorb health from enemies.
- Disc-One Nuke: Due to Chrome Falcon finding an unintended way to sneak into The Very Definitely Final Dungeon, Blossom received "The Destiny" very early in the game's lifespan, with other players being completely unprepared for its power.
- Ill Girl: In real life, she suffered from a degenerative disease.
- Mercy Kill: Requests this of Chrome Falcon after the ARS subject her to being continuously resurrected and killed by the Legend Class Enemy Jörmungand, leaving with only a handful of Burst Points. He complies.
- Posthumous Character: Has long since been deleted from Accel World.
- Too Good for This Sinful Earth: She wanted to live in the accelerated world with the boy she loved even if she couldn't live a full life in the real world, and establish an organization that would allow players to play without the fear of losing Brain Burst. Both dreams are cruelly taken away from her.
Magnesium Drake (2nd Chrome Disaster)A former rising star in the duelling circuit, who participated in the hunting of the original Chrome Disaster only to be taken over by his armour.
- Breath Weapon: Had the ability to breathe fire, which was later mimicked by the Disaster Armor.
- Draconic Humanoid: Resembled a spiky humanoid dragon.
- Posthumous Character: Died long before the start of the series, but is brought up by veteran Burst Linkers to point out the unnerving resemblance between him and Wolfram Cerberus.
Centaurea Sentry (3rd Chrome Disaster)One of the previous Chrome Disasters, who was slain by Blue Knight.
- Implausible Fencing Powers: His signature ability, which was inherited by the Disaster Armor.
4th Chrome DisasterAn unnamed Burst Linker who was defeated by an alliance of the Kings of Pure Color. After suffering total point loss, their armor was secretly retrieved by Yellow Radio.
- An Axe to Grind: Is shown to wield a brutal-looking axe.
- Big Creepy-Crawlies: A huge, long-limbed avatar, with a long neck that looks somewhat like a mutated centipede.
- Posthumous Character: Is depicted only in a Flash Back.
Cherry Rook (5th Chrome Disaster)
The "Parent" of Scarlet Rain, the second Red King. Once it became clear that he couldn't catch up with Yuniko, he sank into despair and resorted to using the Disaster Armor to gain more power.
- Cyber Cyclops: As Chrome Disaster, has a single glowing red eye. His original form has a more conventional face.
- Grappling-Hook Pistol: His signature ability, "Wire Hook", launches an invisibly thin wire from his palm, ending in a hook. To those unfamiliar with the ability, it can seems like he's flying or drawing in opponents through telekinesis.
- In a Single Bound: His "Super Jump" ability.
- Not Quite Flight: The combination of his Wire Hook and Super Jump grants him great mobility, which motivates Rain to track down Silver Crow to corner him.
- Obsolete Mentor: Was the one to introduce Niko to Brain Burst, but rapidly saw her outshine and overtake him.
- Only Known by Their Nickname: Is only every known in story as Cherry Rook, his real name is never known or spoken.
- Parental Abandonment: Like Yuniko, he doesn't have parents. The fact that he gets adopted by relatives and ends up having to leave the facility only exacerbates his issues about Scarlet Rain surpassing him.
- Put on a Bus: He gets adopted by relatives and taken far away from Niko, although they promise to keep in touch.
- Unwitting Pawn: In Yellow Radio's scheme to defeat Scarlet Rain.
Silver Crow (6th Chrome Disaster)See the Nega Nebulus section for more details
- All Your Powers Combined: Bonds with the armor so completely that they can wield the combined abilities of all previous Chrome Disasters, though this has the side effect of making their fighting style much more sloppy and predictable.
- That Man Is Dead: When challenged to a duel, starts to announce their name and affiliation, only to decide they have no right to them any more, simply introducing themselves as "Sixth Chrome Disaster".
A Level 7 Burst Linker and former member of Purple Legion. He moved to Okinawa three years before the start of the series after his parents' divorce. He is also a high school freshman, Lagoon Dolphin's "parent", and "master" of Lagoon Dolphin and Coral Merrow.
- Awesome Mc Coolname: Before he disappeared from Tokyo, he was famously known as "The Burst Linker with the Strongest Name". Since all Burst Linkers are Japanese citizens of Tokyo, few understood the English word "kingbolt". It's a world where only the strongest Burst Linkers earned the title of King, yet "King" was actually a part of his name, so those who didn't really know about him trembled when they heard he was coming. Even the "bolt" part of his name added to his legend; the Purple King, being a master and lover of lightning, had him recruited to her legion before ever meeting him because she assumed he was named Bolt because of a similar electrical nature. Though his title is meant partially as a joke, it also alludes to the respect afforded him as one of the truly strongest Burst Linkers in the Accelerated World.
- After becoming the parent to two newbie Burst Linkers in Okinawa, he exaggerated his reputation somewhat, leaving off part of his title and claiming that he was known as "The Strongest Burst Linker". Kuroyukihime, who knew the truth, did not tell his students the whole story because of her respect and affection for Crimson Kingbolt.
- Partially because his Duel Avatar's full name was considered simply too awesome, even for him, his friends and allies, like Black Lotus, called him "Crikin" for short.
- Big Brother Mentor: To Coral Merrow and Lagoon Dolphin.
- Drowning My Sorrows: Takes to hitting the virtual bottle because he and his students have no hope of defeating a mysterious Burst Linker who doesn't appear on the matching list in the real world, and who has tamed a legendary monster to rampage around in the Unlimited Neutral Field.
- Humongous Mecha: If he gathers up a large enough pile of scrap metal, he can use his Mega-Machine Awakening ability to merge with it and transform into an enormous humanoid robot. While it's considerable firepower cannot compare with Scarlet Rain's Immobile Fortress, the Mega-Machine is considerably more agile, capable of leaping shocking distances for something so large. Between this agility and a humanoid form (including actual hands), Crimson Kingbolt's mecha could theoretically engage in close combat with enemies large and small in a way that the Immobile Fortress can't.
- In-Universe Nickname: "Crikin".
- Large Ham: He can be very overdramatic.
- Macross Missile Massacre: Until Scarlet Rain's ascent, he had the strongest long-range firepower in the Accelerated World's history. Despite not even being the original Level 9 Red King of Pure Color.
- Something We Forgot: Black Lotus, Lagoon Dolphin and Coral Merrow completely forget about him sinking in the sea after defeating Sulfur Pot.
Ruka Asato/Lagoon Dolphin
A Level 5 Burst Linker from Okinawa. She is the "parent" of Coral Merrow and the "child" of Crimson Kingbolt, as well as the latter's real-life cousin.
- Boyish Short Hair: She has short hair to go along her tomboyish and brash personality.
- Curtains Match the Window: Her hair and eyes are the same color.
- Dark-Skinned Redhead: She has red hair and tanned skin and she's a pretty impulsive and energetic girl.
- Fiery Redhead: She has red hair and has the brash personality to go along with it.
- Naïve Newcomer: Like her friend Mana, she gives out her name to Kuroyukihime when meeting her in real life. In their case, their naivete is largely the result of few other Burst Linkers coming to Okinawa.
- Red Oni, Blue Oni: The impulsive and rash Red Oni to Mana's calm and polite Blue Oni.
- Spirited Competitor: She challenges Black Lotus to a duel for the fun of it.
- Tomboy and Girly Girl: The tomboy to Mana's girly girl.
Mana Itosu/Coral Merrow
A Burst Linker from Okinawa and the "child" of Lagoon Dolphin.
- Naïve Newcomer: Rather naive when it comes to Brain Burst given they give out their names to Kuroyukihime when the met her in real life.
- Pink Means Feminine: She's the girly girl to Ruka's tomboy and she's completely pink as Coral Merrow.
- Rapunzel Hair: As Coral Merrow.
- Red Oni, Blue Oni: The calm and polite Blue Oni to Ruka's impulsive and rash Red Oni.
- Tomboy and Girly Girl: The girly girl to Ruka's tomboy.
Shihoko Nago/Chocolate PuppeteerMaster of the minor Legion "Petit Paquet", a Level 4 (later Level 5) avatar resembling a girl in a chocolate-brown dress and bonnet. Introduced in volume 12, and along with her teammates, joins Nega Nebulus in volume 17.
- Contest Winner Cameo: One of the avatars designed for a contest, who ended up having a larger role than originally planned. Though given the nature of some of her scenes, Kawahara both thanks and apologises to her designer in the afterword (insisting his editor put him up to it).
- Dungeon Bypass: The Legion Master Quest normally requires four people, but her Chocopets allowed Petit Paquet to do it with three.
- Eating the Enemy: Her Chocopets reform from physical damage, requiring attackers to burn them, freeze them... or eat them.
- Fluffy Tamer: Forms a bond with a "Lava Carbuncle" Enemy which she nicknames Coolu, watching over and feeding it.
- Improvised Golems: Her Puppet Make summons autonomous chocolate puppets ("Chocopets") from the pools created by her Cocoa Fountain move.
- In-Universe Nickname: Usually called "Choco".
- It Is Pronounced "Tro-PAY": Pronounces her avatar's name as "Chocolat Puppeter", finding the proper English a bit of a mouthful.
- Mucking in the Mud: Her Cocoa Fountain move creates a pool of chocolate (up to 30 meters in diameter if she spends her entire special attack gauge) which both slows enemy movement and can be used to fuel her other abilities.
- Power-Up Food: Eating her Chocopets restores a small amount of the special move meter.
- Super Cute Super Powers: Summons delicious chocolate via beams of pink light (matching her eyes, which she describes as "the colour of strawberry cream").
- You Taste Delicious: When Crow asks if her armour is really made of chocolate, she says everyone asks that and tells Crow to taste her hand just to get it out of the way. Unfortunately, Haru is both a Big Eater and currently starving, so he becomes distracted analysing her fingers' exquisite flavour and keeps licking, greatly weirding Choco out.
Mint MittenChocolate Puppeteer's Parent.
- In-Universe Nickname: Chocolate Puppeteer calls her "Min-Min".
- Superpowered Evil Side: One of the victims of the ISS Kit.
Plum FlipperChocolate Puppeteer's Child.
Megumi Wakamiya/Orchid Oracle
Secretary of Umesato Junior High Student Council and a good friend of Kuroyukihime. She is also a Burst Linker who lost her memories of the game upon a defeat.
- Clingy Jealous Girl: In Episode 24, she is visibly annoyed to see Haruyuki approaching Kuroyukihime, who has just stepped off a train (with Megumi still onboard).
- Geo Effects: One of Orchid Oracle's abilities is to forcibly change battle stages.
- Laser-Guided Amnesia: She's forgotten her time as a Burst Linker, but subconsciously hears a voice calling her, thus enabling her to briefly connect and save Kuroyukihime.
- Magical Girl: Her Duel Avatar looks like one.
- Skinship Grope: She likes to grope Kuroyukihime.
A mysterious Burst Linker introduced in volume 7, where he initially introduces himself as "Trilead Tetraoxide". Themed after a feudal lord, he lives in the Imperial Palace (Brain Burst's Very Definitely Final Dungeon), and has had minimal contact with players other than his Parent.
- Antiquated Linguistics: Speaks in a manner fitting his appearance.
- Iaijutsu Practitioner: Wields one of the Seven Arcs, "The Infinity" - a sword that grows stronger over time while sheathed, with no upper limit, but resets back to its base stats after each use.
- Mundane Utility: His sword is potentially the strongest weapon in Brain Burst, but due to the one-shot nature of its attack he relies more on his own skills in combat, using its power only to attack the barrier that prevents players from entering or leaving the Imperial Palace.
- Spell My Name with an "S": Is it "Azure Heir" or "Azure Air"?
A bunch of nameless Avatars that appear on the sidelines and usually watch Crow fight.
- Contest Winner Cameo: All the avatars are from a "Design your own Avatar!" contest hosted a while back.
- Almighty Janitor: Implied given his high level of intelligence in deducing Burst Linker identities.
- Author Avatar: Appears to be a stand-in for Kawahara himself
- Creator Cameo: Tin Writer (the gray colored, glasses-wearing metal avatar) in Japanese is voiced by the author himself.
- Leaning on the Fourth Wall: In Accel World vs Sword Art Online he mentions he has knowledge coming from a higher level but in a different way to Metatron, possibly alluding to the fact that he's an Author Avatar. Ironically, his appearance in this game is not voiced by the actual author.
- Spot of Tea: Loves to drink tea with others.
One of the Burst Linkers Silver Crow battled against with Aqua Current. She uses the electric poles in her palms to control the flow of electric current.
- Huge Guy, Tiny Girl: Tiny Girl to Sand Duct's Huge Guy.
Nickel Doll's partner. He uses the ducts in his hands to create a sandstorm vacuum.
- Huge Guy, Tiny Girl: Huge Guy to Nickel Doll's Tiny Girl.
Kyouya Shinomiya/Mirror MaskerArdor Maiden's "Parent" and (deceased) real-life older brother. His duel avatar was part white and part silver, with a shape reflecting his lifelong training as a Noh performer.
- Ironic Death: Dies in real life when one of his family's giant Noh mirrors falls and shatters on him.
- Mirrors Reflect Everything: His signature ability, "Theoretical Mirror", made light-based attacks useless against him.
- Non-Standard Character Design: Like Maiden his avatar is two-tone, something highly unusual in a system that places so much emphasis on an avatar's signature colour.
- Posthumous Character: Dies before the start of the story, leaving a deep mark on Utai. His history becomes relevant when his "Theoretical Mirror" ability is brought up as a possible counter to Metatron's One-Hit Kill laser, with the other Legions spurring Silver Crow (as the duel avatar currently closest to a mirror) to try developing the same ability.
- Boss in Mook Clothing: Even the weakest Enemies are strong enough that managing to defeat one solo is a sign of serious badassery, yet the rewards for doing so are usually pitiful. Blue Knight's title of "Legend Slayer" grants him almost mythical status.
- Cycle of Hurting: In a scenario referred to by Burst Linkers as an "Unlimited EK" (Enemy Kill), an avatar is killed by an Enemy and respawns before the Enemy has left. If not somehow interrupted, this results in said avatar repeatedly dying and respawning until their Burst Points hit zero and they're left Deader Than Dead. Over the course of the story, various factions have tried to Exploit this process as a way of assassinating their rivals.
- Elite Four: There are two groups of Legend-class Enemies with abilities beyond other members of their kind:
- Magic Is a Monster Magnet: Not only is the Incarnate System less effective against Enemies, they can "hear" it and are drawn to its location. This makes it extremely dangerous for Incarnate users to fight each other while in the Unlimited Neutral Field.
- Piñata Enemy: In addition to the small number of Burst Points they grant when defeated, some weaker enemies will also drop a card that can be converted into a large number of additional points. This isn't actually a game mechanic - rather the Green King, Green Grandee, spends long hours farming points from stronger enemies and distributing these cards in order to help low-level players stay in the game.
- Tier System: Divided into Lesser, Wild, Beast and Legend classes, with a semi-official God class for some Final Boss Enemies.
Tropes associated with the Four Deities:
Sun God Inti
- Foreshadowing: Before the Four Deities are properly introduced, Inti is briefly mentioned as a powerful boss that Graphite Edge once tried to defeat by luring it out of its normal grounds and into a lake.
- Sinister Sentient Sun: Takes the form of a miniature sun that vaporises anything it comes in contact with.
Archangel MetatronFinal Boss of Contrary Cathedral, one of Brain Burst's four great dungeons. The Acceleration Research Society somehow gained control of Metatron, using her to guard the location of the ISS Kit Core.
- Asskicking Equals Authority: Capable of ordering lesser Enemies to simply go away, as long as they're not being controlled by something else.
- Blue and Orange Morality: Self-declared:"I have no concept of good and evil as you do, and I have no interest in the squabbles of little warriors. However, I have no intention of breaking my vow to lend you my strength."
- Bonus Boss: Normally intended to be fought in the Hell stage, which strips her of her most deadly abilities... but if somehow defeated outside of the Hell stage, she enters a secret second form.
- Boss Arena Idiocy: Metatron's insanely powerful abilities are meant to be balanced by the Dual-World Gameplay of the Contrary Cathedral dungeon where she appears, becoming drastically weaker when players step on a panel that switches the dungeon to "Hell" mode. In the overworld, however, the appearance of the Heaven and Hell stages is vanishingly rare, turning her into a Hopeless Boss Fight.
- Cast from Hit Points: If she's somehow incapable of gathering sunlight for her Trisagion, she can sacrifice her own energy instead.
- Celestial Paragons and Archangels: Named after Metatron.
- Equippable Ally: Once freed, she creates a fairy-like extension of herself that can transform into the powerful Enhanced Armament "Metatron Wings", boosting Crow's attack power and flight speed.
- Exposition Fairy: Her terminal acts like a Sour Supporter version of this, though she can't talk while in Enhanced Armament mode.
- Feather Flechettes: In monster form, the twelve giant "feathers" on each wing can be launched as projectiles, then return to her.
- Fusion Dance: Briefly fuses with Crow in the fight against Wolfram Disaster, granting him her durability and Multiple Life Bars, though the aftermath ensures that they can't soon do it again.
- Gold and White Are Divine: Her human form wears white clothing with gold trim, and is sometimes depicted illuminated by gold light.
- Gratuitous Greek: Her attacks are named after Greek religious terms used in the Eastern Orthodox Church.
- Insistent Terminology: She will have you know that the proper term for inhabitants of the Unlimited Neutral Field like herself is not Enemy but Being, thank you very much. And don't you dare call her Ektenia something as crude as "that wing attack".
- "Instant Death" Radius: Her Trisagion has a very long range and is powerful enough to vaporise even Green Grandee, Brain Burst's ultimate Stone Wall. Thankfully, she only uses it to keep people from approaching.
- Intangible Man: Outside of the Hell stage, Metatron is intangible and almost invisible unless the emission point for Trisagion is damaged, which will force her into physical form.
- Kaiju: One of the largest bosses in Brain Burst, transported out of her dungeon to perch on a Tokyo skyscraper.
- Mystical White Hair: In her human form.
- Our Angels Are Different: Initially introduced as a freakish translucent Kaiju which doesn't resemble any living creature, her second phase causes her "horn" to detach and transform into a woman with ribbonlike wings.
- Our Monsters Are Weird: Has ten legs, four "wings" that look like rows of unconnected fins, a body made out of layered rings, a long tail ending in a beak-like structure, a spherical head that spits lasers and drills, and a horn that transforms into a different creature if the body is destroyed. And is usually transparent. When Haru tries to get his allies to aim for the forehead, Niko first has to ask where that even is.
- Razor Wings: Ektenia ("Litany") lets the Metatron Wings shoot forward to skewer targets, implied to be a smaller-scale version of Metatron's Feather Flechettes attack.
- Sesquipedalian Loquaciousness: A mild example, but compounded by her use of unusual terminology unfamiliar to Burst Linkers (such as calling the Duel Field "the lower field" and referring to the Twilight stage as "field attribution HL06").
- Shock and Awe: Can generate a wide-area blast of purple lightning by spinning her body segments against each other.
- Sour Supporter: Assists Haru through her "terminal" out of obligation, but takes every opportunity she can to spell out how unhappy she is about it.Haru: "Metatron... thanks."Metatron: "Refrain from pointless utterances."
- Spark Fairy: Her miniature "terminal" takes the form of a diamond-shaped jewel with a halo and two smaller jewels resembling wings. Haru thinks it looks more like a selection cursor or an AR map marker than an object players can interact with.
- Telepathy: Can communicate telepathically with Silver Crow, though she isn't very forthcoming about information. She can talk too, but is disgusted by the thought of "lesser beings" hearing her voice without good reason.
- Wave Motion Gun: Her Trisagion ("Thrice Holy") gathers sunlight through her wings to fire an incredibly powerful blast.
- Woman in White: Her human form has both white robes and white hair.
- Sealed Evil in a Can: Was "defeated" once in the early days of Brain Burst, but merely trapped in her dungeon rather than being killed.
Chiaki Chigira/Aluminum Valkyrie
The main protagonist of the manga spin-off Dural: Magisa Garden, Chiaki recently returned from America, enrolling into an all-girls school. Her brother used to tell her stories about a "Snow Black Princess" and her adventures in a magical kingdom before he died. Seeing an opportunity, two of her seniors try to install Brain Burst on her, only to be rejected. Turns out her brother already installed it three years ago on his deathbed, and is an unknowing Avatar.
- Animal Motifs: Idolized Kuroyukihime to the point where her own public avatar is designed around a swallowtail butterfly.
- Badass Adorable: She is a very cute young girl and quite badass in real life, thanks in no small part to her years of study in America where she learned parkour and several martial arts.
- Berserk Button: She does not take too fondly to people talking about her height. Even if someone isn't actually talking about her height.
- Blood Knight: She loves a good fight and loves looking for one in the hope of growing stronger so she can be more like Kuroyukihime.
- Charles Atlas Superpower: Smashes her teacher's desk with one foot on her first day. And that's just as a greeting.
- Fingerless Gloves: Wears a set of fingerless gloves.
- Hair Antennae: Has two rather butterfly like antennae.
- The Heroine: Of her own spin-off.
- Hero-Worshipper: Towards Kuroyukihime.
- Hot-Blooded: Very much so. Especially when it comes to combat.
- Knight in Shining Armor: The female Valkyrie type.
- The Napoleon: She does not like her height being brought up.
- Shana Clone: Not surprising, considering the fact that Ayato Sasakura, the artist of Dural, also worked on the manga adaptation of Shakugan no Shana. She's just more of a Genki Girl than most examples.
- To Be a Master: She wants to become the eighth King to impress Black Lotus.
Yuuko Hoori/Orange Raptor
Head of Enbuken. In the real world wears a bear head on her swimsuit for some reason.
- Breath Weapon: One of her special moves. Deca Flare.
- Everything's Better with Dinosaurs: Her Avatar looks like a dinosaur with a scarf wrapped around its neck for some reason.
- Girlish Pigtails: The most girlish of the group with the pigtails to match.
- Ms. Fanservice: To begin with, she wears nothing but a two-piece bikini in the middle of school.
- Scarf Of Asskicking: Her Duel Avatar wears one.
- Shameless Fanservice Girl: Again spends most of her time in two-piece bikini in the middle of school!
Kurumi Kuruma/Violet Dancer
Member of the Math Research Department staff martial arts division. In the real world has a habit of cross-dressing, garnering herself many fans in their all-girls school. Her avatar looks like an exotic Arabic dancer.
- Bifauxnen: Her overall appearance in real life complete with short hair and penchant for boyish clothing.
- Boyish Short Hair: Her short her really helps with her Bifauxnen look.
Lilya Usachova/Iris Alice
Russian-Japanese student and newcomer to the Math Research Department staff martial arts division. She had been bullied because of her lack of proficiency with Japanese. Eventually becomes Yuko's "child".
Has an Alice in Wonderland motif to her design and attacks.
- All of the Other Reindeer: Before she met Yuko.
- Your Mind Makes It Real: Lilya has a worse nightmare than anyone else in the cast or, for that matter, in the Accel World, as her trauma causes her to materialize a giant monstrous rabbit to destroy her enemies. Nothing less than the Chrome Disaster can possibly match.
- Charles Atlas Superpower: Her reaction rate is said to be far higher than Chiaki.
