About Corrector Yui

Set in a future where a single global network called COMNET runs almost everything, Corrector Yui follows Yui Kasuga, a normal schoolgirl who knows almost nothing about computers. After an accident in a school lab she encounters IR, a raccoonlike corrector program that insists Yui is the key to stopping Grosser, a rogue AI that was originally meant to manage COMNET. Yui is hesitant because she lacks skill and confidence, so the series watches her learn and grow while hunting down Grosser's hench-programs. To stand a chance she needs to find seven other wayward corrector programs and the network's creator, Professor Inukai, so they can work together to protect the connected world.

Premiered in 1999, Corrector Yui was created by Yuji Mutoh and Michitaka Kikuchi, and features voices by Makiko Ohmoto, Mugihito, Yuko Kagata, Kae Araki and Akiko Kimura. The show blends magical girl tropes with sci fi elements in an anime targeted at younger viewers.

There are no widely reported major awards or nominations for Corrector Yui. It didn’t receive mainstream prize recognition, but it continues to be listed in anime databases and cited by fans who remember its late 90s broadcast and home releases.

Although never a blockbuster, the series developed a modest fanbase that appreciates its quirky mix of cute character design and network-focused sci fi. Fans often recall the raccoonlike corrector IR and the premise of a childable heroine handling digital threats, and the show gets occasional mentions in retrospectives about 90s anime that toyed with internet-age anxieties.

General reception is modest and uneven, with a user rating around 7.55/10 from a small sample. Viewers tend to praise its kid-friendly approach to big ideas, like the ethics of centralized systems, trust in AI, and teamwork, while noting simple animation and episodic plots suited to younger audiences rather than adult-oriented complexity.

What Viewers Are Saying

7.5/10
from 11 ratings

Fans describe Corrector Yui as a magical girl show that doubles as cyberspace antivirus fiction, a vibe that lands somewhere between Mega Man Battle Network and .Hack//Sign. The tone is darker and more tech oriented than most mahou shoujo, with solid side characters and lively team dynamics, even though the English dub was unfinished back in the day. Nostalgia runs strong for many, who recall watching it in the mornings with coffee and see it as a quirky gem from an era when US releases were spotty, even as some critique its episodic structure.
