Totsuko is a high school student who has the ability to see the “colors” of others. The colors of happiness, excitement, and calm, as well as a color you consider your favorite. Kimi, his classmate at school, radiates 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 in an antique shop in a remote corner of town. As they practice in an ancient temple on a remote island, music brings them together and ignites friendships and emotions. Will they discover their true “faces”?
