Yui Kasuga (春日 結, Kasuga Yui) / Corrector Yui (コレクター・ユイ, Korekutā Yui)

Voiced by: Makiko Ohmoto

A 14-year-old girl of dubious academic skill, has aspirations to become a manga artist and/or voice actress. Yui has shown skill and growth over the series as she assumes the secret on-line identity of "Corrector Yui". While utterly incompetent when physically interfacing with computers, in ComNet has the abilities to correct computer virus or software bug and a tremendously powerful fighter as Corrector, able to quickly undo damage and easily battle the strongest of Grosser's henchmen. Her optimistic view and her ability to cheer up others even at the worst moment (though sometimes she can be quite perky) was one of her greatest strengths, making her easily likeable by her peers a fellow Corrector programs. She also has an empathetic personality that helps her understand the nature of AI programs she meets on the ComNet. In 1st season, it was revealed that her singing voice had ability to normalize programs. In 2nd season, she upgrade to Advanced Elemental Suit. In finale, she upgraded to Final Element Suit.

Haruna Kisaragi (如月 春菜, Kisaragi Haruna) / Corrector Haruna (コレクター・ハルナ, Korekutā Haruna) / Dark Angel Haruna (エビルハルナ, Ebiru Haruna)

Voiced by: Yuko Kagata

Yui's best friend. She has a polite, calm, and caring personality. Her intelligence and innate ability with computers, and her voice that enable to normalize programs had makes her a perfect candidate for Corrector, as expected by Professor Inukai. From the beginning she was supposed to be a Corrector, but I.R. confused her with Yui, thanks to Grosser's intervention. When Professor Inukai was passing Corrector tasks and abilities to her, she got manipulated by Grosser, who turned her into Dark Angel Haruna, but she was eventually saved by Yui. In the 2nd season, she again returns as a Corrector to assist Yui, first when Yui got petrified by infected insects, and later, when she helps Yui until the end of the 2nd season. Curiously, she can use Element Suits more effectively than Yui. Her Basic Elemental Suit reminds of angel.

Ai Shinozaki (篠崎 愛, Shinozaki Ai) / Corrector Ai (コレクター・アイ, Korekutā Ai)

Voiced by: Kae Araki

Shun's cousin. A dark and mysterious girl who becomes a Corrector on her own in the second season. Her bitter experience in the past seems to be the reason for her cold, apathic demeanor as a mask to protect herself. While at most times she does her job by mostly cold, no-nonsense efficiency, Yui's action sometimes force her to reconsider and help Yui. She became a Corrector to search for the "little girl", believing that she might be connected with her mother's coma. While at first she rather despised Yui, and considered her little more than a nuisance, in the end she admires her optimistic view of life, and her ability to cheer up others. Her Basic Element Suit is reminiscent of the maid.

Eight softwares have close relationship with Yui throughout the show (Except for I.R. have same appearance as humans). Originally one software called the Corrector, but broken down into eight softwares under Grosser's attack. As such, each piece of software concentrates on a specific task, and Yui must learn to integrate their skillsets to defeat Grosser's minions, and eventually, Grosser himself.

Control (コントロル, Kontororu)

Voiced by: Hiroki Takahashi

Corrector Software No. 1, The Regulator. Yui meets him in a space adventure site (not unlike an MMORPG). He has the ability to practically stop time for a limited time, enabling him to move at light-speed velocity. His power in the Wind Element Suit makes Yui able to stop time for about 15 seconds, and if other Correctors (such as I.R.) borrow its power, the time can be strengthened to 30 seconds. He has a "hero-guy" type personality and insists on being the team leader and great hero (treats Yui like a damsel in distress, said he didn't need a woman's help, always tries to go first without everyone's concern, tries to steal the spotlight every time, has some narcissistic streak, etc), which at first makes Yui tend to dislike him, and sometimes puts him at odds with the other Correctors, though he is actually a nice. He is mainly a comic relief for the show (especially 2nd season).

Synchro (シンクロ, Shinkuro)

Voiced by: Takashi Matsuyama

Corrector Software No. 2, The Synchronizer. Not much is known about this Corrector, since he was lost at the beginning of the series. At the end of the first season it is revealed that he was corrupted and became the Corruptor program War Wolf. His ability is similar to Wolf (using fire bursts as weapons), and one of the Correctors that has excellent fighting abilities on his own. His power of fire can be bestowed to other Correctors, to let them access the Fire Element Suit. He has a loyal personality, seems to have some feelings for Yui (refused Professor Inukai's orders to run from Grosser and goes save Inukai, or is the one that opposes Inukai's decision to transfer Corrector power from Yui to Haruna, refuses to become Haruna's ally and confesses in front of Inukai he want to follow Yui until the end). Beagle infections force him to stay in War Wolf form for most of the 2nd season, reminding him of his bad deeds in the past, causing him to become rather explosive, and Yui's attitude doesn't help either (she always call him "Doggy" out of habit, which annoys him). In the finale, He's back to true form and hugged with Yui who blushed.

Ante (アンティ, Anti)

Voiced by: Michiko Neya

Corrector Software No. 3, The Predictor. Yui meets her on a love fortune-telling site. Has ability to foresee the future. Her visions, though most of time accurate, can sometimes deviate, especially when she doesn't have enough data/knowledge about the subject (like when Yui hugged her, when her vision in which Yui shakes her hand, when they first meet, and when she is trapped in Rapunzel's tower on the fairytale simulation). Has wise, maternal personality. Her power enables Yui to access the Wind Element Suit and enables Yui to predict the enemies' movements and attacks. She often becomes a subject for Control's flirting, but thanks to her ability, she can evade most of it (leaving Control in distress).

Eco (エコ, Eko)

Voiced by: Kumiko Watanabe

Corrector Software No. 4, The System Maintainer. Yui meets him on a rainforest like simulation. He has the ability to control nature, like water and plants. His power helps Yui to access the Water Element Suit, and she can control nature at will, using it as defensive, recovering, or offensive tools. He has a rebellious, childish personality, and dislikes anyone who desecrates nature, to the point of kidnapping everyone who litters on the rainforest simulation. When Yui meets him, he at first hates Professor Inukai, whom he believed had left him, but he finally learns that Dr. Inukai actually loves him, just like the other Correctors, and left him there for his own safety.

Rescue (レスキュー, Resukyū)

Voiced by: Akiko Kimura

Corrector Software No. 5, The Repairer. She has the ability to heal damage, including Element Suit damage, and when she lends her power to Yui, Yui can perform a barrier in the Water Element Suit that can knock back attacks. She has a sweet, rather naive (to the point of perky), and polite personality. While she is not prone to fighting, her fighting style includes applying non-lethal force as much as possible (like using a "tickler machine" and bug spray), and also using a vast array of traps and gadgets (she is notoriously known among the other Correctors for this, she even dubbed herself the "Trap Princess"). All her antics and naivety especially disturbs Freeze (whom Rescue seems interested in). In the 2nd season, she fights using bandages from her halo, anti-Beagles spray, and can also detect virus sources by using a radar on her halo.

Peace (ピース, Pīsu)

Voiced by: Kazuhiko Nishimatsu

Corrector Software No. 6, The Archiver. A pacifist old man who claims himself to be a "Peace Defender", who ironically has a knack for building destructive weapons. At first he disliked Yui for destroying the solitude he gained at the remote area he inhabited, but later he helped her drive away Grosser's Corruptors by lending her his power. His power enables Yui to access the Fire Element Suit, with the "Flame Bomber" projectile attack. A wise person, he always speaks what he feels is right, even if it makes conflict with the other Correctors. In the 2nd season, from his data, the villain cloned him to wreak havoc on the ComNet, giving the distraction they needed to carry out their plan.

Follow (フォロー, Forō)

Voiced by: Shinobu Satouchi

Corrector Software No. 7, The Compiler. Yui first met him, along with Peace, at a secluded area, separated from the main domain of the marine adventure simulation created by her father's company. A fat guy with a playful, sweet, almost childish demeanor. He likes Yui at first sight, because "she is cute". He has the ability to mimic practically anyone, and copy some abilities from the one he is mimicking. He is also the one with the biggest memory power out of all of the Correctors, and when he lends his power to Yui, Yui's power (and also her weight) in her Basic Element Suit changes greatly, and can also activate her Earth Element Suit. He's Peace's good friend. His ability to mimic others can sometimes be quite a nuisance for others, like when he teases Freeze by mimicking Rescue.

I.R. (IR, Ai Āru)

Voiced by: Tomohiro Nishimura

Corrector Software No. 8, The Installer. The first Corrector Software Yui meets, also Yui's best friend; I.R. always nags Yui about her duty as Corrector, sometimes making Yui annoyed to the end.

He made the Basic Element Suit for Yui from a magic girls outfit stored at Galaxy Land, went download it to Yui until Season 2. he can also access the Earth Element Suit, giving Yui a large physical power boost, making her on par with Jaggy.

His contact with Yui; a girl who cried to computer thrown in the garbage made him want to "live", and later, to tried create the world where he could "live". Professor Inukai thinks it's fatal error and create the Correctors softwares to delete his mind. When Inukai chooses Haruna as Corrector, Grosser, who was fascinated with Yui from the beginning, manipulated I.R. and set Professor Inukai in accident, so that Yui would be the Corrector instead of Haruna. He even went as far as to turn Haruna into Dark Angel Haruna. In the 1st season finale, he pretended to be defeated by Yui and Correctors but possesses Shun's body, he confesses that he want to be Yui whom his dearest human and tried to convince Yui to let him her body, Yui could see through the disguise, and instead, she convinces him that he actually is a living being himself, capable of feeling happiness, pain, and sadness, and also Correctors and Corruptors who are softwares over the net. She also stated that for the sake of others who love her, she can't just quit to become herself, though sometimes she is bitter and sad. Grosser, who finally sees the error of his ways, deletes himself along with the whole ComNet, sparing a pretty much-devastated Yui. But at last, with moral support from Haruna, she could use her power and reinitialize the whole ComNet again.

While she seems innocent and bears no harm, when emotionally pressured, and she sheds tears, her tears become the core for the Beagles virus. She is always searching for "sunflowers". Her picture was found within a storybook that belongs to Ai Shinozaki. Originally, she was created by Shintaro Ishikawa as a messenger software for his daughter. Ryo took her, experimenting on her with many computer viruses (not unlike Lisa Trevor), and thus the Beagles Virus was created with her as the host. Her name is "Ai", same with Shinozaki Ai. This girl can feel the emotions of others, which causes Ai to always lose her track, due to her heart's closure to others (which at first, she blamed on the ComCon, using logical deduction).

He promised a large sum of reward money for Freeze, stopping her from asking too much about the job. In the end, it is revealed he is just a mere pawn, controlled by another mastermind.
