Wit Studio Apologizes for AI Backgrounds in Ascendance of a Bookworm

The opening credits freeze on my screen and a dozen fans are already screenshotting. You feel that small, sinking click—the moment a show you trusted looks like it was half-made. For Wit Studio, that click echoed into a public apology.

I’ve followed anime production for years, and you probably have strong feelings about who draws what. Let me walk you through what happened, why the backlash landed so hard, and what it means for studios that promise human craft while flirting with generative tools.

Fans paused the new episode and shared screenshots — the opening looked off

The anime was Ascendance of a Bookworm: Adopted Daughter of an Archduke, streaming on Crunchyroll. Viewers noticed backgrounds in the first episode’s opening sequence that carried the telltale glitches and awkward textures many now associate with AI image generation. Screenshots spread fast on X (Twitter), and the thread of complaint tightened into a public roast.

Within days Kotaku and other outlets ran the story. Wit Studio responded on April 10, six days after the premiere, admitting an internal review found generative AI used in cuts of the opening. Their statement promised to redraw the offending background for episode two and to replace the opening sequence in episode one, while also reaffirming a general policy against generative AI in production—blaming the lapse on production-management failures.

Did Wit Studio use AI in Ascendance of a Bookworm?

Yes. Wit Studio publicly confirmed limited use of generative AI in the opening cuts of episode one after fan reports and screenshots. They said the use was an exception, and named the art studio involved—NAM HAI ART—as not responsible for that specific incident.

The team had a prior experiment, and fans reminded them of it

Back in 2023, a short called Dog and Boy credited AI directly in the production notes. The experiment—made for Netflix’s creators-and-tech initiative—listed AI for background art and music, even giving credit lines like “AI (+ Human)” without naming the supervising artist. Fans never forgot the awkward crediting, and this recent slip felt like history repeating.

Netflix Japan defended that short as an “experimental initiative” involving rinna’s image generation, framed as a response to industry labor shortages. Critics pointed out that the real problem wasn’t experimentation but how credit and compensation for human artists were handled—an issue that keeps resurfacing when studios lean on automated tools.

I remember interviewing George Wada, Wit’s president, when the studio was trying to set a different standard—working with CloverWorks on Spy x Family in order to protect staff from crushing schedules. You can feel the cognitive dissonance: a studio that talks about salaried creators and humane schedules, then gets publicly shamed for AI backgrounds that look like they were pasted in by a machine.

This contradiction is jarring, like a seamstress who finishes a gown beautifully and leaves the hem glaringly raw.

What will Wit Studio do about AI backgrounds?

Their public plan is short and concrete: redraw the opening for episode two, replace the first episode’s opening, and revise production guidelines and management checks to prevent a repeat. They framed the problem as a procedural failure, not an editorial choice to substitute human craft with automation.

Audiences and animators kept pointing to the same worry — labor and trust

Fans aren’t just policing aesthetics; they’re protecting the idea that people made what they love. Animators and background artists face low pay and intense schedules across the industry—Mappa’s crunch culture has become shorthand for what studios try to avoid. Using AI in this climate reads as a cost-cutting move disguised as innovation.

AI’s spread through animation can feel like a cracked mirror: the reflection of a beloved show is there, but the surface fractures the image until details are lost.

Wit’s apology addresses the immediate optics, but it won’t fix deeper labor economics or rebuild trust unless it follows with transparent credits, named human supervisors, and clear pay practices. You should watch whether studios like Wit and platforms like Crunchyroll and Netflix start publishing who did what on every episode—including tools used and names of the human artists—because fans and professionals will judge by deeds, not promises.

How common is AI in anime production?

It’s increasing, especially for experiments, shorts, and in some background or in-between work. Companies like rinna and other image-generation toolmakers have run pilots. But transparency varies: some projects credit AI bluntly, others bury it in production notes. That inconsistency is a major part of today’s debate.

For you and me as viewers, the key is simple: if a studio says it prefers hand-made art, it should match actions to words. If it worries about shortages, pay artists a living wage instead of substituting human skill with automated shortcuts. Brands will lose credibility fast if audiences keep catching them half-finishing the job.

Are studios ready to choose between speed and the craft that built anime’s fandom, or will the compromise keep eroding trust?
