Tenshi, Ei-chan, and Shiratori all attend Kawagoe Academy. One day, they get pulled into the orbit of former conductor Haruo. He drags them into his newly founded boys choir where they suddenly find themselves performing a song in front of an audience!

It's a cool song, so why don't 
we give it a try? Just for today.
إنّها أغنيةٌ رائعة، فلمَ لا نجرّب الأمر؟ لليوم فحسب
Das Lied ist doch ganz cool.
È un brano niente male.
É uma música bacana.
Она вроде классная. Может,
попробуем хотя бы разок?
