Totsuko is a high school student with the ability to see the “colors” of others. The colors of happiness, excitement, and serenity, as well as the color she considers her favorite. Kimi, a classmate at her school, radiates the most beautiful color of all. Although she doesn’t play an instrument, Totsuko forms a band with Kimi and Rui, a quiet music lover they meet at a used bookstore in a remote corner of town. Practicing in an old church on a remote island, music unites them, forming a friendship and sparking affection. Will they discover their true “colors”?
