Totsuko is a high school student with the ability to see the “colors” of others. He values the colors of happiness, excitement, and peace as his favorite colors. Her school friend, Kimi, embodies the most beautiful color of them all. Although she doesn’t play an instrument, Totsuko forms a band with Kimi and Rui, a quiet music lover who meet at an antique shop on a remote corner of town. While they practice in an old church on a remote island, music brings them closer, forges friendships, and awakens feelings. Will they find their true “colors”?
