Shion, a beautiful and mysterious transfer student, arrives at Keibu High School and quickly becomes popular for her open-hearted personality and exceptional athletic talent, but she is an AI in the testing phase.[5](https://www.rottentomatoes.com/m/sing_a_bit_of_harmony) Her stated goal is to bring \"happiness\" to Satomi, a chronic loner in her class, and her strategy is to serenade Satomi in the middle of the classroom.[5](https://www.rottentomatoes.com/m/sing_a_bit_of_harmony)\n\nOnly Satomi knows the truth about Shion at first. Satomi's mother Mitsuko is an AI scientist at the Hoshima corporation, and her job depends on the success of the covert experiment.[6](https://www.theguardian.com/culture/2022/jan/30/sing-a-bit-of-harmony-review-yasuhiro-yoshiura-strikingly-beautiful-anime-tale-of-an-undercover-ai-schoolgirl) • [7](https://childrenandmedia.org.au/movie-reviews/movies/sing-a-bit-of-harmony) Shion's habit of bursting into song, including hacking the school PA system to play a backing track, soon alerts other students that she is out of the ordinary.[6](https://www.theguardian.com/culture/2022/jan/30/sing-a-bit-of-harmony-review-yasuhiro-yoshiura-strikingly-beautiful-anime-tale-of-an-undercover-ai-schoolgirl)\n\nAfter Satomi and her childhood friend Toma, an engineering enthusiast, learn that Shion is an AI, they and the rest of the class, including the popular Gotchan, the strong-willed Aya, and the judo club member nicknamed \"Thunder\", are gradually moved by Shion's singing and earnestness even as her antics bewilder them. What Shion does for Satomi's sake eventually draws them all into serious pandemonium.[5](https://www.rottentomatoes.com/m/sing_a_bit_of_harmony)\n\n## Production\n\nThe film is an original work, not an adaptation. Yoshiura wrote the original story and screenplay, with Ichiro Okouchi, known for the *Code Geass* series, as co-screenwriter, and manga artist Kanna Kii (*The Stranger by the Shore*) providing the original character designs. Character design and chief animation direction were by Shuichi Shimamura, and the film was animated by J.C.STAFF.[1](https://eiga.com/movie/93749/) • [2](https://www.ainouta.jp/)\n\nYoshiura has said he began planning the project around 2017 and spent about a year building the video storyboard (v-conte) that became a key to the production.[8](https://realsound.jp/movie/2023/09/post-1443732_2.html/amp) • [9](https://toonboom.co.jp/news/toon-boom-interview-files/yoshiura-aiuta) He described the worldbuilding as deliberately grounded: self-driving buses are existing buses retrofitted with AI rather than purpose-built models, and humanoid AI robots are at the stage where companies lend them to schools and have them try rice planting to win public acceptance, because ordinary households still feel psychological resistance to them.[8](https://realsound.jp/movie/2023/09/post-1443732_2.html/amp) The idea of Shion suddenly breaking into song came out of a list of possible personality traits he drew up for the AI character.[10](https://rooftop1976.com/interview/211028120000.php)\n\n## Music and singing\n\nThe film works as a musical: Shion breaks into fully staged musical numbers at a moment's notice, and the score and in-film songs were composed and arranged by Ryo Takahashi with lyrics by Yohei Matsui.[2](https://www.ainouta.jp/) • [4](https://www.bandainamco.co.jp/files/pr20220725_aiuta_g.pdf) The songs are performed by [Tao Tsuchiya](https://www.edgepedia.org/tao-tsuchiya) in her role as Shion.[2](https://www.ainouta.jp/) Yoshiura said he wanted singing motions that feel as if they well up naturally from inside the body out of emotion, rather than the fixed choreography of an idol performance.[9](https://toonboom.co.jp/news/toon-boom-interview-files/yoshiura-aiuta)\n\nThe English dub's songs were a point of critical discussion. The reviewer Grant Watson, an Australian film critic and writer, judged that the English versions of the songs are simply not as good as the Japanese ones and recommended the original-language version for that reason.[11](https://fictionmachine.com/2026/03/12/review-sing-a-bit-of-harmony-2021/)\n\n## Release and reception\n\nThe film opened in Japan on 29 October 2021.[1](https://eiga.com/movie/93749/) It won the Excellence Animation Film Award at the 45th Japan Academy Prizes.[4](https://www.bandainamco.co.jp/files/pr20220725_aiuta_g.pdf)\n\nCritics responded well. On Rotten Tomatoes the film holds a 100% Tomatometer from 10 reviews and a 97% Popcornmeter audience score from more than 50 verified ratings.[5](https://www.rottentomatoes.com/m/sing_a_bit_of_harmony) Wendy Ide of *The Observer* called it a strikingly beautiful anime that is high-concept in its themes and unashamedly sentimental in its execution, becoming more interesting in its darker second half, and compared its questions about what form an AI might take and whether it can love to [Mamoru Oshii](https://www.edgepedia.org/mamoru-oshii)'s *Ghost in the Shell*.[6](https://www.theguardian.com/culture/2022/jan/30/sing-a-bit-of-harmony-review-yasuhiro-yoshiura-strikingly-beautiful-anime-tale-of-an-undercover-ai-schoolgirl) The Australian Council on Children and the Media rated the film PG (mild themes and coarse language) and advised that it is not suitable for children under 8, with parental guidance to age 9, citing mild animated violence and threat, one occasion of alcohol abuse, mild coarse language, and the story's complexity.[7](https://childrenandmedia.org.au/movie-reviews/movies/sing-a-bit-of-harmony)\n\n## Home media and streaming\n\nBandai Namco Filmworks released the film on home video in Japan on 27 July 2022: a special-edition Blu-ray at 10,780 yen with two bonus discs of event footage and music videos, a regular Blu-ray at 6,380 yen, and a DVD at 5,280 yen, all including a barrier-free Japanese audio guide and subtitles.[4](https://www.bandainamco.co.jp/files/pr20220725_aiuta_g.pdf) Rental and digital-sale streaming began the same day, and subscription streaming followed in June 2023, starting with a group of services on 1 June 2023, Lemino on 15 June, and Netflix on 29 June.[12](https://www.ainouta.jp/ondemand.html) Rental streaming was priced at 550 yen (tax included) with a 72-hour viewing window, and digital purchase at 2,546 yen for HD and 2,037 yen for SD.[12](https://www.ainouta.jp/ondemand.html)\n\n## The director's view of AI\n\nYoshiura has returned to the film's subject as real-world AI has changed. He said that when the film was made, the idea of an AI composing music spontaneously still felt like fantasy to him, and that if he wrote the same plot today he would find himself wondering whose work Shion's songs were trained on. He noted that the film was planned at a moment he now sees as a narrow window, before generative AI made AI a contested subject in creative fields, and that his own thinking had shifted since production.[8](https://realsound.jp/movie/2023/09/post-1443732_2.html/amp) He has also said that with this film he deliberately drew a line: while some people fear AI stepping outside the frameworks humans imagine for it, that fear is not what the film set out to depict.[13](https://cinema.ne.jp/article/detail/48428)\n\n## References\n\n1.
