Makoto (Kyoko Yoshine) transfers to Omotesando High School in Tokyo from Kagawa Prefecture. Makoto was enthusiastic in the chorus back at her old high school and she looks forwards to joining the well-known chorus at Omotesando High School. Additionally, her prior teacher, Ariake Suzuki (Yuu Shirota), is now an advisor of the chorus at Omotesando High School. He taught her the joys of the chorus. But, the chorus at Omotesando High School is now in decline and is set to be abolished. Makoto decides to rebuild the chorus.
