Harmony of Mille-Feuille (2025) – A Beautiful Blend of Voices, Dreams & Emotion | Release Date, Cast & Where to Watch

🎶 Harmony of Mille-Feuille – A Beautiful Blend of Voices, Dreams, and Layers of Emotion


“A singing voice is like mille-feuille — layered, fragile, and unforgettable.”That poetic line defines the heart of Harmony of Mille-Feuille (Japanese: うたごえはミルフィーユ), an upcoming anime series that harmonizes music, adolescence, and emotional depth in a fresh new way.


Launching July 17, 2025, this mixed-media project by Pony Canyon and creator Takuya Yamanaka takes center stage with a full anime adaptation by Jumondou. Combining vibrant characters, the charm of high school friendships, and the technical beauty of a cappella, this anime is poised to hit all the right notes.


🎵 What Is Harmony of Mille-Feuille?


At its core, Harmony of Mille-Feuille is about voices — not just musical, but emotional, personal, and shared. The story follows a group of high school girls with a shared passion for a cappella, an intricate form of vocal music without instrumental accompaniment.


The characters bring their own insecurities, ambitions, and stories to the choir room, each layering their own “voice” onto the group — just like the layers of a mille-feuille pastry. The series beautifully explores the connections formed through music, growing pains, and creative struggles.


👩‍🎤 Main Characters & Voice Cast


The ensemble cast is split into two groups — the main unit and Parabola, another rival vocal group — each with their own unique styles and stories.


🎤 Main Group

  • Musubu Mayumori – Yūko Natsuyoshi

  • Airi Kojō – Kanoko Sudō

With additional characters voiced by talents like Iori Saeki, Mayumi Shintani, and Kaori Nazuka, the series boasts an impressive voice cast that anime fans will immediately recognize.

The theme song "Omoidebanashi" (Nostalgic Talk) is performed by the main cast — a fitting, emotionally rich piece that captures the anime’s tone. With Shun Narita composing the background score, fans can expect lush harmonies and emotionally resonant music throughout.
