Hino Kahoko is a student whose school is divided into two branches - the Normal Branch, in which students wear grey uniforms, and the Music Branch, in which the students wear white. The school's tradition is a music competition, but it it more common that students from the Music Branch are chosen to compete. Kahoko is surprised one day to encounter a fairy named Lili. Solely because she is the only student to see him, she is the only student from the Normal Branch to be in the competition.
