Totsuko is a high school student who has the ability to see the “colors” of others. Colors of happiness, excitement, and serenity, as well as the color he considers his favorite. The most beautiful color is created by Kimi, a classmate at his school. Although Totsuko doesn’t play an instrument, she forms a band with Kim and Rui, a quiet music lover they meet in a neighborhood antique shop. As they rehearse in an old church on a remote island, music brings them together, forging friendships and sparking affection. Will they find their true colors?
