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?
I sing because when the 
melody carrying my wishes
أغنّي لأنّي أريد عندما تصلك
الملحونة التي تحمل أمانيّ
Gesang bedeutet Hoffnung,
hübsch verpackt in eine Melodie.
Canto perché quando la melodia
che trasporta i miei desideri
Canto porque quando a melodia
carrega meus desejos
Я пою, чтобы мелодия
вознесла мои желания.
