First-year high school students Kana, Reimi, and Hibiki are apprentices at the Karasuma Phoniatric Clinic, where the power of healing through song is combined with conventional medicine. One day when the girls' teacher is out, one of the clinic's patients takes a sudden turn for the worse. Is there nothing these apprentices can do to help?
