The Gekijō-ban Hibike! Euphonium ~ Kitauji Kōkō Suisōraku-Bu e Yōkoso~ film will look back at the spring 2015 television series, which depicted a high school concert band's journey to the prefectural band competition. The film will open in Japan on April 23. A separate sequel television anime series will depict what happens afterward.

The spring 2015 television anime adapts Ayano Takeda's 2013 novel, which is also titled Hibike! Euphonium Kitauji Kōkō Suisōraku-Bu e Yōkoso . The story follows the Kitauji High School Concert Band, which used to always advance to national competitions. Ever since the adviser changed, though, it has not advanced past the Kansai tournament. However, thanks to the newly appointed adviser's strict instruction, the students are steadily improving. The band members' daily lives are full of ups and downs including fights over solos and the decision to resign extracurricular activities to focus on studies.

The television anime premiered last April, and Pony Canyon USA streamed the series on Crunchyroll as it aired in Japan. Pony Canyon USA will release the television anime in North America.
