Totsuko is a high school girl who can see the “colors” of others. The colors of happiness, excitement, and peace, as well as one color that she cherishes as her favorite. Kimi, a classmate at her school, has the most beautiful color. Although she doesn’t play an instrument, Totsuko forms a band with Kimi and Rui, a quiet music lover they meet at a bookstore in a remote corner of town. When they rehearse in an old church on a remote island, music brings them together, forges friendships, and ignites love. Will they discover their true “colors”?
