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?
Just like when I sing together 
with you... I feel you
كما عندما أغنّي سويّاً معك... أشعر بك
Immer, wenn wir im Chor singen …
Proprio come quando canto con te... I feel you
É como quando eu junto a você...
Eu sinto você
Ведь когда мы поём вместе...
я чувствую тебя.
