Reception
AI subtitling controversy
Anime News Network noted that the series' official English subtitles had numerous translation errors, and in one line of the German subtitle script, it contained the phrase "ChatGPT said:" prefixing the dialogue, suggesting that ChatGPT had been used to produce the subtitles. Rebecca Silverman criticized the use of ChatGPT in the subtitling, describing the result as "nowhere near acceptable for a professional product". Crunchyroll responded on July 3, 2025, saying that the use of AI for the subtitles violated agreements with the third-party vendor who had supplied them, and that they were working to resolve the issue.
