At the Seijo Academy, which exudes youthful vitality, the freshman Inoue Shinba (voiced by Irino Miyu) accidentally met her senior in the second year of high school, Amano Toko (voiced by Hanazawa Kana), and thus joined the literature club where Amano is the head and she is the only member. Amano is a strange girl. Literature is like food with a different taste to her. She refuses pieces of paper full of words. She is happy to accept beautiful and moving strokes, but she can't bear to abandon bad words. In addition, they also launched a business of writing love letters for the whole school, but there are only a few people who respond. On this day, a long-lost letter was received in the mailbox, but there was only a doodle on the paper. After checking, the doodle turned out to be from the poet and fairy tale writer Miyazaki Kenji. It seems to be a prank, but it evokes Shinba's painful memories of the talented literary girl Inoue Miu and the suicidal girl... This film is adapted from the light novel by Nomura Mizuki.
