Corrector Yui

Yui is an average schoolgirl who lives in a future where all computers are supported by a single global network known as COMNET. Yui is a computer-illiterate girl who after a computer-lab accident is approached by IR, a raccoon looking corrector computer program, which tells her she must save COMNET. She must stop the rogue A.I. (Artificial Intelligence) computer program known as Grosser and his hench-programs from taking over the world. Grosser was originally designed to be that manager of all of COMNET. At first she's very reluctant to play the heroine because of her complete lack of knowledge and ability with computers. To save COMNET she must find and gain the trust of the other seven wayward corrector programs. They must also find the creator or COMNET Professor Inukai, to help stop Grosser for good.

Initially airing in 1999 to 2000, Corrector Yui has only very recently been fully translated to English, which is why there hasn't been much discussion or reviews for it.

[Theme and tone]
Despite being of the magical girl genre, this series' thematic probably has a lot more in common with something like Mega Man Battle Network and even .Hack//Sign, rather than the typical magical girl anime. Its thematic similarities to .Hack//Sign extend to some of Sign's darker themes as well. Notably, the uploading of one's consciousness to a virtual world (and the potential consequences that could arise from that) is a major theme in both series.

While this ... series is pretty light, humorous, and upbeat most of the time, it occasionally has surprisingly dark moments in the story that can range from serious to grim or unsettling. These moments create a nice tonal contrast when they pop up. Much of the story and interactions between characters can also often be surprisingly thoughtful, particularly how side characters interact with Yui and how they develop as characters as a result.

[Plot]
There are two "arcs" in Corrector Yui that are essentially halved up like a "season 1/season 2" kind of deal. The structure of each half of the anime follows that the introduction starts off with a bang that sets the overall plot in motion, then for about the first half of the arc it focuses on introducing and interacting with new characters while the plot partially progresses in the background of each episode, occasionally with some well-executed foreshadowing of plot elements that you likely won't see coming. Characters introduced in the first half of each arc continue to be relevant later on.

In the second half of each arc, the series directly focuses on the main plot and its major characters. A healthy helping of character development occurs in general, though the first halves of each arc in particular serve as nice build ups to the plot and character developments in the second half of each arc (rather than otherwise feeling rushed).

It's worth pointing out that the series has a nice sense of subtlety when foreshadowing major plot elements, this sense of subtlety also typically reflects onto how the characters act. It doesn't quite hit you over the head with how characters really feel in regards to more serious moments. I found this nuance to be refreshing, and it helps make things more tonally consistent in these serious moments.

Overall, I'd say Corrector Yui has a more complex plot than most magical girl series, along with a pretty good build-up to major plot events. Its sense of subtlety will likely ensure that the twists in the story stay surprising. Prior to watching all of it, I had read claims that it had virtually no real plot or backstory. Thankfully those claims would appear to have been a straight-up lie, or perhaps the result of rather poor media literacy.

[Characters]
The protagonist is the titular Yui. She is very kind-hearted, but can be childish and clumsy. Amusingly, given the setting of this anime, she is extremely inept at using computers. She isn't a flawless combatant either, and there are many times she gets overpowered or needs help to overcome obstacles. Yui's character develops really satisfyingly, and she actually proves to be very perceptive and sensible as the story goes on. When things get tough, she is persistently kind-hearted almost to a fault, willing to take significant risks to herself if it means a happier outcome for others. I found her character to be very endearing, and I think she fits the role of protagonist in this kind of story perfectly.

The cast of characters are likeable and have a diverse range of personalities that work well together, particularly since Yui's interactions with each of them are quite entertaining. The interaction between Yui and a certain antagonist (to be vague for the sake of keeping this spoiler free) is particularly interesting and I feel should be noted. They're both great foil characters to each other, and she is the primary factor for his character growth. It's one of my favourite character dynamics in general.

The primary antagonist of the first arc creates a nice sense of mystery regarding his motives, and I feel he served to be a pretty great antagonist in general. The second arc's antagonist doesn't have motives that are quite as engrossing, but the circumstances surrounding them are quite interesting, managing to make good use of a primary theme of the series.

[Comedy]
Comedy is fairly prevalent in Corrector Yui, often taking on a light-hearted humorous tone. It's also my personal favourite genre of anime, and this got a lot of laughs out of me to the point that I'd say the comedic aspect is one of the better parts of the show. Of course, comedy is subjective to some extent, so feel free to disagree. An important part of the execution of comedy lies in the quality of voice acting, which I'd say was done rather well.

Thankfully the comedic aspects are placed and blended in sensibly; without at all interfering with the tone and pacing of more serious moments. Which I'd say is worth mentioning since this does have important portions of the plot that are genuinely dark and/or serious.

[Art/animation]
90's anime typically have my favourite artistic styles, and Corrector Yui provides as such. The linework, shades of colours, and overall style are quite likeable for me, and it's all pretty consistently drawn as well. I very much enjoyed the visuals in general.

I found the animation to be pretty solid, and the fight scenes are usually quite dynamic. Like other anime of its kind, it has transformation and special attack sequences that are reused when appropriate.

[Music]
The soundtrack is sincere, cute, bubbly, and somewhat adventurous. I enjoy it to the point that I've found myself looking it up just to listen to it randomly. It kind of gives me the vibe of a nostalgic video game's soundtrack (though I've only watched this in 2021). I particularly adore the opening of the first half of the series, the singer of which has a rather elegant, soulful, jazzy voice. Easily one of my favourite openings ever.

[Enjoyment/Conclusion]
Corrector Yui is among the best hidden gems of anime I've had the pleasure of experiencing. I enjoyed just about every aspect of it more than I was expecting to, ranging from the story, characters, voice acting, music, and overall style and visuals. I imagine that it's rather obscure simply because it has only been fully translated recently (from the time of this review). Had it been given the translation and marketing it deserved, I'd be surprised if it wouldn't have been held in the same high regard as other major series of its kind.

CorrectorYui

Mixed Feelings

After 3 years watching sporadically and even theming my profile around it, I finally finished this anime.

Corrector Yui is an anime that never really took off stateside with an unfinished dub which is a shame since it has a unique concept with a cyberspace magical girl pretty much acting as an antivirus software...despite said girl being very inept with computers.
It's a very fun anime with enjoyable side characters and humor with its character dynamics that fleshes out both the team of heroes and the team of villains, which is always a plus. Yui, our titular protagonist, has a very cute design and attacks and ... as she gains experience, gets 3 more forms with their own powers that are all distinctly and well designed. Watching her gain confidence in herself as a Corrector and build relationships with her fellow Correctors that are scattered across the world wide web (or ComNet as it's called in-universe) is heartwarming.
So, if I'm singing this anime's praises, why the mere 7/10? The answer lies in pacing.
The first 25 or so episodes are a solid 8, they strike the perfect balance between being episodic and character-driven and being plot and narrative-driven. The Big Bad has a solid build-up in being a formidable foe and there are some fun unexpected twists in terms of Corrector's and their identities.
However, the 2nd half of the show is a solid 6. A new threat and new characters are introduced but the pace slows to a crawl, being heavily episodic and feeling like nothing's happening in the grand scheme of things up until the final 7-8 episodes. The Big Bad is heavily lacking in gradual build-up making the finale feel rushed and new attacks/power-ups come very late into the show, further contributing to that rushed feel, even if there are satisfying and well-earned character development scenes.
So, despite having a good concept and cast along with great art and music, the execution could've been better, leading to my rating having mixed feelings.

Not Recommended

As of the time of writing this review, the craze in the anime scene is isekai. As of the time of this title's release date, (one of) the craze(s) was the success of massive genre defining titles like Sailor Moon and Cardcaptors -- the mahou shoujo genre.

This anime original is pretty much exactly a cashgrab akin to today's filler isekai titles that get an anime adaptation. The show's episode and plot structure is episodic with little to no continuity between one episode and the next. The show is effectively a computer virus take on the battle-mahou-shoujo with the same ditzy heroine tropes and other ... 90s comedy tropes. There is virtually little to no backstory or even plot besides transforming every episode to fight monster-of-the-episode about 50+ times.

Characterization-wise, there are pretty much nothing but caricatures of the memorable characters of genre.

I suppose a child of maybe age 12 or lower may enjoy this anime but for the most part, this show offers nothing that another title of the same genre cannot offer. Moreover it's take on the year 2020's scene of computers is pretty inaccurate (not that the low score had anything to do with this, for more details, see my profile page for the exact rating criteria) and for anyone watching as of the time of this review, you will have a good cringe at what the anime's idea of a computer or advanced AI/technology is.
