The Karasuma Girls help out at the Honosaka Clinic where they see a surprisingly hard-working side of Sonia. But it turns out Sonia also has plans for Kana at their school's upcoming culture festival...
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.
