Totsuko is a high school student with the ability to see the “colors” of others. The colors of bliss, excitement and peace, plus the color she considers her favorite. Kimi, a classmate from her school, emits the most beautiful color of all. Although she doesn’t play an instrument, Totsuko forms a band with Kimi and Rui, quiet music enthusiasts whom she meets in a bookstore in a far corner of town. As they practice in an old church on a remote island, music brings them together, forming friendships and sparking affection. Will they show their true “colors”?
