Fuji TV’s new Blue Lynx boys-love anime label will be producing the film. The television anime focuses on high school students Ritsuka and Mafuyu, but the film actually focuses on the adult band members Haruki, Akihiko, and Ugetsu.

The film will open on August 22 after a brief delay. The film was originally scheduled to release in Japan on May 16, but was delayed due to concerns over the spread of COVID-19 in Japan.

The television anime’s cast members are reprising their roles for the film. Hikaru Yamaguchi (director for Escha Chron, episode director for Mr. Osomatsu, Battle Spirits Double Drive) is returning to direct the film at Lerche. Yuniko Ayana (BanG Dream! both seasons, Girls Beyond the Wasteland) is again writing the script, and Mina Ōsawa is returning to design the characters. Hiromi Kikuta and Michiru are again handling sound direction and music composition, respectively. The artist centimillimental is returning to perform the film’s theme song.

The television anime premiered on Fuji TV’s Noitamina programming block last July. The anime is the “first anime based on a boys-love manga” to air on Noitamina. Crunchyroll streamed the series as it aired, and it describes the story:

Somehow, the guitar that he used to love to play and the basketball games that he found so fun just lost their appeal…

That was until Ritsuka Uenoyama randomly met Mafuyu Sato. Ritsuka had started losing his passion for music in his everyday life, but then he hears Mafuyu sing for the first time. The song resonates with his heart and the distance between them starts to change.

The manga already runs in the Shinshokan’s Cheri+ magazine. Viz Media’s SuBLime imprint for boys-love manga is releasing the series.
