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 his school, creates the most beautiful color. Although Totsuko doesn’t play an instrument, she forms a band with Kim and Rui, a quiet music lover they meet in an antique shop in a remote neighborhood. As they practice in an old church on a remote island, music brings them together, forging friendships and sparking affection. Will they find their true “colors”?
