TV anime series Sound! Euphonium announced two original anime films back in June last year. Originally set to premiere this year, the first film Sound! Euphonium The Movie: Chakai no Finale (劇場版 響け！ユーフォニアム～誓いのフィナーレ～) has been delayed to Spring 2019.
In this film, the protagonist Kumiko Omae is already a second-year student in Kitauji high school. The story will revolve around how Kumiko works hard along with the “junior members” at the school’s concert band club.
The second film will center on Mizore Yoroizuka and Nozomi Kasaki. Its exact title is not clear at the moment.
Sound! Euphonium is originally a novel series by Ayano Takeda (武田綾乃). The story takes place in Kitauji high school, where a group of high school girls in the school band club strive to win the qualifying tournament while facing troubles like disputes and romance. The novel has already got two seasons of anime adaption.
