Totsuko is a high school student who has the ability to see the “color” of others. The color of bliss, excitement and peace, as well as the color she considers her favorite. Kimi, her classmate at school, has the most beautiful color of all. Although Totsuko doesn’t play any musical instrument, she forms a band with Kimi and Rui, a quiet music lover whom they meet at a used book store in the far corner of town. During rehearsals in an old church on a remote island, music unites them, forming friendship and awakening affection. Will they recognize their true self?
