The Colors Within

High school student Totsuko has the ability to see people as colors, and is particularly fascinated with the color she sees in her classmate, Kimi. After following Kimi to a used bookstore, Totsuko accidentally implies she can play piano, leading to her joining a band with Kimi, who can play guitar, and Rui, a boy who collects musical equipment and plays the theremin. The trio's friendships develop as they write music and confront issues in their home lives.
