A third new trailer and key visual have been unveiled for the upcoming Harmony of Mille-Feuille TV anime series, which will begin broadcasting in Japan on July 17, 2025.
The trailer highlights the show’s main theme song “Omoidebanashi,” which is performed by the main cast.
Takuya Sato (Steins;Gate, Fragtime) is serving as chief director of the anime series, with Kiyoto Nakajima as director, Takuya Yamanaka (The Caligula Effect original creator) as series screenwriter and scriptwriter, Chisato Kikunaga (Don’t Hurt Me, My Healer!) and Hitomi Kaiho (Villainess Level 99) as character designers, Kazuhiro Arai (FLCL Progressive) as art director, and Shun Narita (Dark Gathering) as music composer. Jumondou is handling the animation production.
Chie Rico is credited as the original character designer, while Pony Canyon is producing the music.
Meanwhile, the anime’s main voice cast stars:
- • Mirai Ayase as Uta Kamaki (lead vocals)
- • Yuko Natsuyoshi as Musubu Mayumori (first chorus)
- • Kanoko Sudo as Airi Kojo (second chorus)
- • Misato Matsuoka as Rei “Reirei” Konoe (third chorus)
- • Miharu Hanai as Uru “Ururu” Miyazaki (voice percussion)
- • Haruka Aikawa as Yako “Kuma-chan” Kumai (bass)
The mixed-media project was first launched in April 2022 by Pony Canyon and Yamanaka. The project focuses on the themes of “a cappella singing, high school girls, and complex.”
The franchise has inspired several music singles, voice drama adaptations, music videos, and documentary videos featuring singing lessons.
Pony Canyon describes the main synopsis of Harmony of Mille-Feuille as:
First-year high school student, Uta Komaki. She has many weaknesses. But she loves to sing. Aiming for an ordinary youth, she tries to join the light music club as part of her high school debut— only to fail miserably due to her timid nature.
In her despair, Uta encounters a form of music created solely by the human voice — a cappella. There, she finds a group of girls whose imperfect youth is woven together only through their harmonized voices. Even without shining, it’s still youth.
