"You'll go into the recycle bin and be empty-empty-emptied!"
After Kia Asamiya created Steam Detectives for his son, he looked yet again into an unfamiliar genre, this time for his daughter, who was a fan of Magical Girls. He came up with a story that brought the typical wand-waving, miniskirt-wearing junior high girl Twenty Minutes into the Future by making her a regular girl in the real world and a magical girl online.Fourteen-year-old Yui Kasuga is perky, creative, daydreamy... and at a complete disadvantage for someone that lives twenty years in the future: she's so computer-illiterate that she thinks "delete" is a snack food. Luckily for her, her best friend Haruna Kisaragi is a famous computer expert, taught by her father and her uncle. However, Haruna ain't stupid and Yui has to do her own homework, even though the rest of her friends are off to a virtual theme park. Yui puts the homework disk into her computer and manages to screw up so badly that a virtual creature hidden inside it is awakened by just the right key combination. Thinking he's stumbled upon a super-genius, the creature, IR, commands Yui to load her consciousness onto the "Com-Net" (internet) and become a virtual magical girl.Yui immediately jumps at the chance to fight viruses and wear cute outfits (not to mention, one of the first people threatened by the Big Bad is her father), but as she finds out, there's more to the story than this. Eight sentient programs, of which IR is one, have been created by one Professor Inukai, who is comatose after another program named Grosser rebelled against him and overrode his car. Grosser is after these programs, which uphold the very existence of Com-Net (and, since Everything Is Online, the real world too); presumably, he wants to corrupt everything for some unknown goal. Yui is commissioned to gather all eight and combine their powers with her own to delete Grosser.Yui might turn to cliche once in a while, but in other respects, it's very different. The title character actually wants to be a magical girl, and has dreamed about it and written like stories for a long time. She has a few basic powers with her Fairy Elemental Suit, but each Corrector Program can grant her a different Elemental Suit with different powers, varying the battle tactics. And though the plot might seem straightforward, never fear: Grosser and his Corruptor Programs aren't simple Card Carrying Villains, Inukai's not such a saint himself, the Correctors have their own personalities and quirks, and both Yui and Haruna might not be what they think they are either.
Affectionate Nickname: Yui likes to call War Wolf, to his disgust, as "Doggie" without any teasing from her side (originally it was because she couldnít remember his name). It eventually gets carried on when Synchro returns to his Fearsome Four self-appearance during the second season, something that he initially didnít like it either.
Batman Gambit: How Grosser manipulates Haruna to separate Yui from her Corrector friends and then controlling her. The planner knew their mark would do it to keep Yui out of danger.
Beach Episode: Also counting as a Breather Episode after a whole wham arc and just before the first seasonís climax. In it, Control decides to take a break with his teammates as an excuse to prepare an attack plan against Grosser, while looking for his whereabouts.
Body Horror: Second anime season: The Boggler Virus not only forcibly turns Synchro into War Wolf, but at some point it briefly forces a struggling, panicking Corrector Haruna to beat up Yui with her rod, until Corrector Ai comes in a Big Damn Heroes entry.
Haruna was under the influence of Grosser in the first season.
Grosser ALSO manipulates Shun before the big battle in the first season (and then he possesses him).
The Boggles Virus often manages to change the sitesí NPCs personalities to aggressive ones, and some of the humans that would get trapped in the infected sites would be affected as well... Freeze not only falls once but twice (the latter more dangerous than her previous Fearsome Four role, when the main villain of the second season revealed their real intentions about her "part time job").
Evil Costume Switch: When normal, Corrector Haruna's white and pink suit makes her look like an angel, white bird wings included. When she's Brainwashed and Crazy, it becomes red and black, with bat wings and a devil's tail.
Paint It Black: The Angel and Devil Suits might be separate, but their user's alignment summons one or the other, rather than the switch being intentional.
Magical Girl: The three Corrector girls: Yui, Haruna and Ai.
Magic Music: Yui uses this against Haruna, and later against Grosser.
Mailer Daemon: Grosser's subconscious met Yui and became amazed by (and obsessed with) her when she was a little girl. This developed into him becoming somewhat of a Stalker with a Crush when he saw her again, although even he didn't know why for a long while.
Screw Destiny: Yui was not destined to be a Corrector and at some moment she was about to fully give the mantle to the *real* Chosen One, but ultimately she changed her mind and came back. Just in time, since Haruna was Brainwashed and Crazy.
Superhero Speciation: In the anime and the Okamoto manga, the Corrector Program to Elemental Suit ratio was 2:1, although the powers varied [for example, Yui could get the wind suit from Anti and see the future, or she could get the same suit from Control and stop time]. In the Asamiya manga, though, every program got their own suit.
Taken for Granite: Yui and Freeze, among others, in an episode of the anime's second season. That triggers Haruna's return.
