Totsuko is a high school student with the ability to see “colors”; others. The colors of bliss, 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 enthusiast they meet at a used bookstore in a remote corner of town. As they practice in an old church on a remote island, music brings them together, forming friendships and igniting love. Will their true ‘colors’ reveal themselves?
