Studios face AI backlash
Several social posts noted a QC failure where WIT Studio admitted using AI for opening backgrounds against internal rules, and creators criticised studios like Monsta for accepting low‑quality AI work on kids franchises. The thread frames a growing tension: studios use AI for speed, but artists and audiences are calling out 'AI slop' when it shows up in visible, paid work.

A backlash over artificial intelligence imagery in animation sharpened this month after WIT Studio said it used generative AI for some opening backgrounds in *Ascendance of a Bookworm* and promised to replace them. (automaton-media.com) The fourth season premiered on April 4, 2026, and Crunchyroll published the creditless opening the same day. On April 10, WIT Studio said an internal investigation confirmed AI-generated backgrounds were used in parts of that sequence. (crunchyroll.com, automaton-media.com) WIT Studio said its “general principle” is not to allow generative AI in its animated content, and blamed the incident on weak production management and quality control. The studio said it removed the opening from YouTube and would start airing a redrawn version from episode two. (automaton-media.com, kotaku.com) The dispute lands in a business that already runs on tight schedules, subcontracting and visible credit rolls, so even a few seconds of suspect artwork can be traced and recirculated by fans. In this case, the questioned images appeared in a paid, front-of-show sequence rather than in an internal test or a studio demo. (crunchyroll.com, automaton-media.com) WIT Studio had already made one public exception to its anti-AI stance. In its April 10 statement, the studio said the only prior case was *The Dog & The Boy*, a short film made to test the technology. (automaton-media.com) The criticism has spread beyond Japanese television anime to children’s franchises built for mass online audiences. Monsta, the Malaysian studio behind *BoBoiBoy* and *Mechamato*, describes itself as a producer of family entertainment with global reach, while its official YouTube channel lists 19.5 million subscribers and billions of views across flagship series and films. (monsta.com, youtube.com) That scale helps explain why artists react strongly when low-grade AI-looking assets show up in commercial work aimed at children: these are not obscure experiments, but heavily distributed shows, movies and clips tied to merchandise, licensing and streaming rankings. Monsta’s site says *Papa Zola The Movie* drew 4.4 million cinema admissions in Southeast Asia and that *BoBoiBoy* ranked No. 1 on Netflix in Malaysia, Indonesia, Singapore and Vietnam in October 2025. (monsta.com) Studios, for their part, have framed AI as a production tool rather than a replacement for whole shows. WIT Studio said no other AI-generated assets were used in *Ascendance of a Bookworm* beyond the opening scene it flagged, and said it would redraw those backgrounds from scratch. (automaton-media.com) What changed this week is that the argument moved from abstract fear to a named studio, a dated admission and a visible fix. WIT Studio’s apology on April 10 turned a fan-side accusation into a documented production failure, and that is likely to shape how future credits, openings and promotional videos are scrutinized.
