Totsuko is a high school student with the ability to see “colors” in others. The colors of happiness, excitement, and peace, as well as the color she considers her favorite. Kimi, a classmate at her school, radiates the most beautiful color. Although she doesn’t play an instrument, Totsuko forms a band with Kimi and Rui, lovers of quiet music that she meets in an antique shop in a corner of town. As they practice in an old church on a remote island, music brings them together, makes friends, and inspires love. Will they discover their true “colors”?
