Hino Akiharu lost his parents when he was small and was adopted into his uncle's family. He didn't want to be a burden on his uncle's family and decides to enter a free boarding school as a butler, Hakureiryou high school. However, his delinquent boy-like appearance frightens the girls, who make up the majority of the students. Unable to get along with the classmates, Akiharu meets his childhood crush Saikyou Tomomi.

The protagonist of the story, Konoha Inoue, is a seemingly normal senior high 2nd year student. His high school life, other than a hinted incident 2 years ago, can be summed up as normal- if one can dismiss the secret fact that he used to be a female bestselling romance author. Due to that incident, however, he has now vowed never to write again. This continued on until he was forced to join the literary club by the literary club president, the 3rd year female student Amano Tooko, a beautiful girl who has a taste for eating literary works. Now he has been tasked with writing her snack every day after school. (Source: To Say Nothing of the Dog)

Liz's days of solitude come to an end when she meets a blue bird in the form of a young girl. Although their relationship blossoms, Liz must make a heart-wrenching decision in order to truly realize her love for Blue Bird. High school seniors and close friends Mizore Yoroizuka and Nozomi Kasaki are tasked to play the lead instruments in the third movement of Liz and the Blue Bird, a concert band piece inspired by this fairy tale.

However, as they rehearse, the distance between Mizore and Nozomi seems to grow. Their disjointed duet disappoints the band, and with graduation on the horizon, uncertainty about the future spurs complicated emotions. With little time to improve as their performance draws near, they desperately attempt to connect with their respective characters. But when Mizore and Nozomi consider the story from a brand-new perspective, will the girls find the strength to face harsh realities? A spin-off film adaptation of the Hibike Euphonium! series, Liz to Aoi Tori dances between the parallels of a charming fairy tale, a moving musical piece, and a delicate high school friendship.
