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.

Take care when locking up!
انتبهن عند إقفال المكان
Schließt das Tor
ordentlich ab, ja?
Que no se les olvide cerrar.
No os olvidéis de cerrar.
N’oubliez pas de fermer à clé.
State attente quando chiudete!
Não se esqueçam de trancar tudo.
Проверьте, закрыты ли все двери!
