Harmony of Mille Feuille is slowly tuning itself into one of the most heartwarming entries of the Summer 2025 anime season. With its soft visuals, musical themes, and an ensemble of emotionally grounded characters, the show has just dropped a brand new trailer, key visual, and a full preview for Episode 1. Alongside these announcements, a music video of the opening theme has also been released, stirring both curiosity and emotion among viewers.
The anime centers around a quiet high school girl named Uta Komaki who enters her first year with dreams of joining the light music club. But unlike the confident students already part of it, Uta’s timid and self critical personality becomes her biggest hurdle. As the show opens in April, we witness her awkward hesitation and emotional vulnerability as she stands on the edge of something life changing. This gentle yet relatable approach to storytelling is exactly what gives Harmony of Mille Feuille its charm.
Produced by Studio Jumondou, the anime is directed by Kiyoto Nakajima with writing by Takuya Yamanaka. Character designs are handled by Chisato Kikunaga and Hitomi Kaiho, lending the show a visual softness that complements its emotional tone. The newly released trailer offers glimpses into this world filled with music, friendship, and the inner turmoil of teenagers who are still figuring out where they belong.
Adding to the anticipation, the music video for the series’ opening song “Omoide banashi” has also been released. It blends scenes from the anime with lyrical visuals, creating a moving introduction to the emotional landscape the show is ready to explore. The song itself sets the tone with its gentle melody and nostalgic mood, hinting at themes of growth, longing, and finding harmony within chaos.
The cast brings together a talented lineup of voice actors. Misato Matsuoka plays the lead character Rei Konoe, though she will not be present at the upcoming live commemorative event for the show’s theme song. However, other main cast members will be in attendance at the Pony Canyon Head Office event on August 3. Mirai Ayase will appear as Uta Komaki, Yuko Natsuyoshi voices Musubu Mayumori, Kanoko Sudo plays Airi Kojo, Miharu Hanai portrays Uru Miyazaki, and Haruka Aikawa brings Yako Kumai to life. This live event will mark one of the first big interactions between fans and the show’s universe, providing a more immersive connection for those already emotionally invested.
Episode 1 is officially scheduled to premiere on July 17, and preview images alongside the synopsis are now available on the anime’s website. The first episode promises to capture Uta’s initial struggles and her first impressions of high school life. Viewers will follow her as she stumbles emotionally but quietly begins to observe the bonds and melodies forming around her. It is a character driven beginning that leans into realism rather than dramatics, promising a story that grows as its characters do.
Harmony of Mille Feuille is setting the stage for a coming of age journey grounded in vulnerability, small victories, and emotional expression through music. The show aims to resonate with anyone who has ever hesitated to take the first step or felt lost in a room full of noise. With each announcement, trailer, and visual, it continues to invite viewers into its quiet but deeply resonant world.
