A Story Built Around a Promise
Kimi to Hanabi to Yakusoku to, which can be translated as You, Fireworks, and Our Promise, follows a high school boy whose ordinary life changes after an unexpected confession from a girl he has never met before.
The girl claims that her grandmother once told her about meeting a boy with his name in the future. At first, he believes there must be some mistake, but when she mentions a painting of fireworks, he decides to help her search for the truth behind the mysterious connection.
What begins as a strange encounter gradually turns into a story about memory, fate, first love and the emotional weight of promises that seem to cross time itself.
Main Trailer Highlights the Film’s Emotional Tone
The newly released trailer places strong emphasis on the relationship between the two leads, showing quiet school moments, summer scenery and the recurring image of fireworks as a symbol of connection and longing.
Rather than relying on large-scale fantasy action, the film appears focused on atmosphere, character emotion and the fragile uncertainty of youth. This gives the project a softer, more introspective identity, especially for fans who enjoy romantic anime films with a touch of mystery.
New Visual Captures the Summer Feeling
The promotional illustration reinforces the movie’s nostalgic summer mood, presenting the main characters in a composition that reflects both warmth and melancholy.
Fireworks play a central visual role, suggesting that the film’s emotional climax may be tied to a specific memory, promise or moment shared between the characters.
From Light Novel to Anime Film
The movie is based on the light novel written by Kaori Mado and illustrated by Akamoku. The story was later published under Shogakukan’s Gagaga Bunko label and also received a manga adaptation.
The anime film is directed by Kei Suzuki, with animation production handled by SynergySP and The Answer Studio, while Shin-Ei Animation is involved in planning and production.
A Promising Summer Romance
With its main trailer and new visual now revealed, Kimi to Hanabi to Yakusoku to is steadily building anticipation among viewers who enjoy emotional romance stories, quiet supernatural mystery and summer-themed anime films.
As its July release approaches, the film promises a heartfelt story about two young people, a strange confession and a promise illuminated by fireworks.
