[[folder:The Human Correctors]]
!!Yui Kasuga
->Voiced by: Creator/MakikoOhmoto (JP), Creator/MariaFernandaMorales (LA)

A middle school student who assumes the online identity of "Corrector Yui". She is pretty clumsy, but a dreamer and as long as the story goes, she not only gets the trust of her teammates, but grows on taking the responsibility of maintaining order in [=ComNet=]. She takes the MagicalGirl role by pure accident, when IR thinks she is an "expert on computers" (which she isn't).
* AscendedFangirl
* BrownEyes: She has a trustworthy character, and compared to her friends (both virtual and human) who are more specialized in computers than her, she is the most down-to-earth from them. Yui also can make huge PuppyDogEyes when she is in trouble.
* ChildhoodFriends: Yui has been friends with Takashi during all their lives, making a more deep connection with him (which is why Haruna, sometimes, is jealous about their close friendship), even if it's just to be bickering each other.
* CuteClumsyGirl: She can easily be distracted by the cuteness when she is supposed to be fighting a virus... which sometimes is very unhelpful for her or her teammates.
* DaddysGirl: Her dad still sees her as a child and is very overprotective to her. Heck, he even does his best to spoil her, taking advantage of his web designer and web developer's job.
* GeniusDitz: She is naive with computers' knowledge, but she has a very good singing voice and is a great artist. She even realized at first instance that [[spoiler:Ai Shinozaki is ''Corrector Ai'', even if it was for a single dialogue she told her as both (but then, no one believed her because ''anyone could be anyone on the Internet'')]].
* GenkiGirl
* HairAntennae: Her distinctive hairstyle has one that denotes her [[TheDitz ditzy personality]].
* HeroicBSOD: She suffers three through the first season, all of them related to her role as a MagicalGirl.
* TheHeroine
* IKnowYoureInThereSomewhereFight: She pulls this to [[spoiler:both a manipulated Corrector Haruna and a controlled Shun]], because she didn't want to do any harm to them. ''They work''.
* JumpedAtTheCall
* KindheartedSimpleton
* LightFeminineAndDarkFeminine: The light to Ai's dark.
* LiterallyLovingThyNeighbor: She has a huge crush on her neighbor Shun.
* MaleGaze: A fourteen-year-old girl with a young adult woman figure. And her TransformationSequence puts a lot of emphasis on her hips, her breasts and her butt.
* OtakuSurrogate: She aspires to be a manga artist and a voice actress... and she is also a MagicalGirl.
* PinkHeroine: Her signature costume as a MagicalGirl, as seen on advertising, is a fairy-inspired pink tutu.
* PlatonicLifePartners: With Takashi. She has been friends with him ever since they were children.
* PrecociousCrush: Yui met Shun when she was four years old, and since then, she developed a crush on him.
* ScrewDestiny: [[spoiler:She wasn't the ChosenOne at first. It was all a mistake that IR made along the way when they first met. However, at the time she reunited all the software programs, she eventually wasnít just leading them but she also ended up befriending them, and didnít want to let them down when Haruna assumed the leadership.]]
* SerialRomeo: Once Shun is in America, she starts falling in love with other [[{{bishonen}} cute]] guys she meets.
* SmittenTeenageGirl: Towards Shun.
* TheUnchosenOne: [[spoiler:Professor Inukai had Haruna in mind to be the human corrector that would lead the correctors, but Grosser intercepted IR to make Yui the one... imagine her surprise when Inukai informs her that she wasn't supposed to be their leader...]]

!!Haruna Kisaragi
->Voiced by: Yuko Kagata (JP), Mayra Arellano (LA)

Yui's best friend from middle school. She is a mild mannered girl who is believed to be a computer-knowledgeable genius.

She later assumes the Corrector Haruna online identity at full, when Yui's life is in danger.

* TheAce: Haruna is very smart, and very acknowledgeable on computers. [[spoiler:For this reason alone, Inukai wanted her to be the original leader of the Correctors. And it shows as well, when she assumes her role as Corrector Haruna to rescue Yui, as she manages to use the four Element Suits ''perfectly'' at the first ''try''.]]
* BareYourMidriff: Her element suit is the only one of the three that includes a midriff section.
* BewareTheNiceOnes: Please don't push her buttons too much, especially when it regards to her friends' lives.
* BrainwashedAndCrazy: [[spoiler:Grosser manipulates her as part of his plan in the first season.]]
* DarkMagicalGirl: [[spoiler:When controlled by Grosser.]]
* EvilCostumeSwitch: Her Element Suit has an angelic motif and a light colors scheme (turquoise, white, and pink). Her ''other'' Element Suit [[spoiler:(when being controlled by Grosser)]], while it resembles similar pieces of her original suit, it is [[EvilIsSexy made sexier]], and has gloves and tall boots, with a color scheme which consists mostly of black and red.
* GoodWingsEvilWings: The convenient motif of her element suit is that it resembles an angel, but when [[spoiler:she gets [[BrainwashedAndCrazy brainwashed]] by Grosser]], it resembles a devil.
* GreenEyedMonster: While she is a gentle girl with everybody, she also envies Yuiís bright and friendlier personality, when she partly feels as a loner. [[spoiler:This makes it easier for Grosser to manipulate her, especially in the manga.]]
* IdiotHair: Her hairstyle has a cowlick, and though she is a ''little'' naive, Haruna is actually very smart.
* InvisibleParents: While they appear off-screen, it is implied her parents are {{workaholic}}s and that they are barely at home. However, they do appear if only for a few panels of the manga, [[spoiler:worried about her when she falls into a coma, thanks to Grosser]].
* MissedTheCall: [[spoiler:Haruna was Professor Inukai's first choice to be the Correctors' leader but IR confused her with Yui, thanks to Grosser.]]
* MissionControl: She assumes her full role as Corrector, [[spoiler:when Yui falls victim from a Bogglesí infection]].
* NiceHat: Her Element Suitís cap resembles an angel's halo.
* PaintItBlack: [[spoiler:When Haruna gets fully brainswashed]], her suit instantly gets corrupted as well, becoming more or less a [[EvilIsSexy sexier]] version of the Angel Element Suit, resembling a devil, instead.
* ShrinkingViolet: She slowly gets better, especially after she starts opening much better with help of Yui.
* SilkHidingSteel
* SubmissiveBadass
* TeamMom: Haruna is supportive and has a maternal instinct for her friends. She then preferred to be on the sidelines [[spoiler:when she turned down her leader role as a human corrector]]. However, this change once she decides to help Yui in the battlefield.

!!Ai Shinozaki
->Voiced by: Creator/KaeAraki (JP), Laura Ayala (LA)

A mysterious girl who becomes a Corrector in season two. She becomes the temporal neighbor of Yui, living with her aunt (Shunís mother), once Shun goes to America to keep studying Medicine.

She is the daughter of computer scientists Shintaro and Asuza Shinozaki, and becomes a corrector only because she needs to find a little girl.

* AloofAlly: Ai is more capable of handling a virus alone since the very start compared to Yui and Haruna.
* AloofDarkHairedGirl: She is tall, beautiful, dark-haired and aloof.
* AntiHero: She doesnít consider herself as an ally to Yui (and the other correctors share the same thoughts), especially since she is working on her own and doesn't want to be associated with her. At least, her stanc changes as time keeps progressing.
* BeautyMark: Has a little mole below one of her eyes.
* BrokenBird: [[spoiler:Ai used to be a sweet child, but when her dad died when she was only four, she had to force her emotions for her mom. She eventually became a loner, and her classmates think that shee seems to be ''too perfect'' at everything, to a point where they think she is someone who only thinks highly of herself. Things got a turn for worse when her mom fell into an accident concerning some work behind [=ComNet=] with a colleague of hers.]]
* DarkMagicalGirl: [[spoiler:She takes the role of corrector, firstly and mostly only for her own ambition of helping her comatose mom, whose conscience has been lost online for so long, that from one moment or another, she could be declared clinically dead if she never regains it. And considering her only alive relative is her aunt (whose son is studying overseas)... well...]]
* DefrostingIceQueen: Mostly thanks to Yui, who helps her not only to improve her personality, but also wants to be her friend.
* LightFeminineAndDarkFeminine: The dark to Yui's light.
* LonerTurnedFriend: At the end, [[spoiler: Yui becomes her first friend and she starts opening to the rest of the correctors]].
* OneWayVisor: She is first seen using a visor that suggests her mysterious nature. However, this visor actually helps her to identify and locate virus outbreaks, working in a similar manner to Rescue [[spoiler:and Freeze]]'s attribute.
* ProperTightsWithASkirt: Her Love Element Suit is based in the outfit of [[{{Meido}} a maid]].
* PurpleEyes: Her eyes tie her as an important character for the plot of the second season. And she is very, ''very'' important for the plot of the series as well. [[spoiler: Her father was one of the few scientists tied to the creation of [=ComNet=], to mention just an example.]]
* TheSnarkKnight: Sometimes. Especially when Yui or the Correctors are around.
* TallDarkAndSnarky
* UsedToBeASweetKid: The young Ai we see in flashbacks was a really sweet CheerfulChild.


[[folder: Software Programs/Correctors]]
->Voiced by: Creator/HirokiTakahashi (JP), José Luis Reza (LA)

He is the corrector software #1, also known as "The Regulator". His element motif is Wind. He was found by Yui in a Science Fiction MMORPG net disguised as a SpacePirate called Shadowcat.
* {{Bishounen}}
* ItsAllAboutMe: Heroic example, as he's very egocentric but has a good heart underneath.
* JerkWithAHeartOfGold: At the very start, Control didn't sympathize with Yui, since he felt she was robbing his limelight as the leader of his team, and because he wanted to work at his own rhythm comapred to hers. However, he started to open up when he recognized that Yui was more of a ''leader'' than he was. He also does care about his comrades, even when they don't obey his orders.
* TheLancer
* PeekABangs
* ShoutOut: His Captain Shadowcat disguise is a homage to Creator/LeijiMatsumoto's ''Anime/CaptainHarlock''.

!!Synchro/War Wolf
->Voiced by: Takashi Matsuyama (JP), Bardo Miranda (LA)
->(as War Wolf) Takashi Matsuyama (JP), Miguel Ángel Ghigliazza (LA)

Synchro is the software program #2, also referred as "The Synchronizer". He has the power of Fire. He is the last software to be found since he was under the identity of War Wolf, one of Grosser's Fearsome Four. Under the identity of War Wolf, he is a skilled combat fighter, and retains his snarky side towards his companions and the correctors, especially Yui. Synchro eventually returns to his War Wolf identity thanks to the infection of the Boggles virus at the start of season 2, and is only released from it at the very end.
* AmbiguouslyBrown: His skin color is darker than his teammates'.
* TheBigGuy: Synchro is one of the tallest correctors, and he is also more body-built than Control. He is loyal to his teammates and is the first to act when there is direct combat involved.
* BodyguardCrush: It's hinted through the entire series that he ''could'' have some feelings for Yui. Sometimes even before returning to his original identity, he started developing ''something'' for Yui that is very strongly implied to be romantic. It was even one of the triggers that made him eventually return to his former self. Later, he proves to be loyal to her and even if she still bothers him with an AffectionateNickname, he can't be mad at her just because of ''that''.
* BrainwashedAndCrazy: Grosser transformed him into War Wolf in the first season. Synchro was protecting Inukai's life, and just because of his stubbornness and loyalty to Dr. Inukai, Grosser wanted him to be on his side.
* CoolSword: His main weapon is a sword that reminisces a [[Franchise/StarWars Jedi light saber]]. No wonder, since Asamiya is a ''Star Wars'' fan.
* SavageWolves: As War Wolf.
* TallDarkAndSnarky
* YouGottaHaveBlueHair: Has purple hair.
* UndyingLoyalty: To Inukai and [[BodyguardCrush Yui]].

->Voiced by: Creator/MichikoNeya (JP), Circe Luna (LA)

Corrector Software #3, The Predictor. She has the Wind elemental power in her. When the Professor dispersed the correctors for their own sake, she took the role of a popular FortuneTeller, whose site was later corrupted by Grosser.
* {{Seer}}: She falls mostly in the FortuneTeller side, since she sees the future (and because she assumes that role hiding from Grosser). Most of the times, her predictions are accurate, but with Yui... they are more unexpected to her.
* SilkHidingSteel: Kind, soft-spoken, very cool-headed.
* TeamMom
* YouGottaHaveBlueHair: Her hair is green.

->Voiced by: Creator/KumikoWatanabe (JP), Isabel Martiñon (LA)

Corrector Software #4, The System Maintainer. His element motif is Water. He becomes the MysteriousProtector of the Nature Net after the Professor dispersed the eight Software Programs.
* AdorablyPrecociousChild
* BrattyHalfPint: Special mention, since he attacked innocent people in Nature Net before Grosser got there.
* DisguisedInDrag: In the manga, he was disguised as a girl who is taking care of the Nature Net just to trick Grosser and his minions.
* GreenThumb: He is the protector ''and'' controller of Nature, since Ecology is also the motif of his name.
* MakingASplash: Especially having the Water Elemental Power.
* MouthyKid
* MysteriousProtector
* NatureHero
* RefusalOfTheCall: It took Yui quite the effort to recruit him, since he has a loyalty to his ''DisappearedDad'', Professor Inukai, but then he starts to like her, when she proves to be ''mature''. [[spoiler: This is again shown when Haruna was re-recruiting the correctors, but now it was thanks to the loyalty he had to both the professor AND Yui.]]
* TheResenter: Mostly towards Synchro... especially for burning the forest he protects when he was War Wolf. In fact, this is something that was played very seriously in the Okamoto manga, since [[spoiler:it's the trigger of tension between him and Synchro that Haruna, already manipulated by Grosser, uses to ''try'' to disperse the already-reunited team]].
* UndyingLoyalty: To Inukai.

->Voiced by: AkikoKimura (JP), Elsa Covián (LA)

Corrector Software #5, The Repairer. Her Elemental power is related to Water. During the dispersal of the correctors, she was hidden in the Medical Net, seeking the Professor on her own.
* TheChick
* GeniusDitz: Very childish, but also an excellent medic and a ''really'' good trickster.
* GreenEyes
* HairAntennae
* HairDecorations: The sort of "halo" she has above her head is also a virus radar.
* TheMedic: She has curative powers related to the Water element.
* SilkHidingSteel: As said above, while she's a non-combatant she's very dedicated and hardworking.
* WrenchWench: Besides being a medic, she is a very good traps builder.

->Voiced by: Kazuhiko Nishimatsu (JP), Armando Rendiz (LA)

Corrector Software #6, The Archiver. His motif is Fire, something very [[{{Irony}} ironic]] since he does not approve of violence. He was, alongside Follow, on a remote island hidden in the Marine Adventure Net.
* BadassGrandpa: In appearance he is the oldest corrector, but, even if he is peaceful, he can build efficient weapons for the security of his teammates.
* GeniusBruiser
* GrumpyOldMan
* JerkWithAHeartOfGold: He can act very reluctant at times, but if he is meaning to do his work, he does a lot for his teammates.
* NiceHat
* TechnicalPacifist: As in ''ironic'', since he also represents Fire (an element related to violence) and he builds weapons.

->Voiced by: Shinobu Satouchi (JP), Enrique Mederos (LA)

Corrector Software #7, The Compiler. His elemental power is Earth. He was, alongside Peace, on a remote island hidden in the Marine Adventure Net.
* BigBeautifulMan
* BigFun
* EyesAlwaysShut
* ShapeShifter: He even sometimes take the role of TheTrickster because he can change into any form, from human to animal [[spoiler: especially when bothering Control in a Spy-themed episode, taking the form of Ante just because she didn't have the time to accompany him.]]
* YouGottaHaveBlueHair: Light blue hair, in his case.

->Voiced by: Tomohiro Nishimura (JP), Luis Daniel Ramírez (LA)

Corrector Software #8, The Installer. He has the Earth elemental power. He was the one who Professor Inukai sends to look for the human corrector who will reunite the Software Programs and stop Grosser.

* MentorMascot
* TheSmartGuy

* BigBad: Of Season 1.
* IJustWantToBeYou: It is... a bit more creepy in the manga. [[spoiler:He does not want Yui to be his wife... he WANTS to be her.]]
* MailerDaemon: [[spoiler:His subconscious met Yui and became amazed by (and obsessed with) her when she was a little girl.]]
* PinocchioSyndrome: [[spoiler:As pointed above, he wants to know how is living as a human.]]

* DarkChick
