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...
That's why it feels like the sky 
deep in our hearts is blue and clear
لذا كأنّ السماء في أعماق قلوبنا
زرقاءٌ وصحوة
Deshalb fühlt sich mein
innerer Himmel ach so blau an …
Ed è per questo che il cielo nel profondo
del nostro cuore sembra limpido e blu
É por isso que o céu
no fundo do coração é todo azul
Потому и кажется, что небеса
наших сердец синие и ясные.
