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!

Yup, I could hear you singing
with your whole bodies!
!أجل، سمعت غناءكم بسائر أجسادكم
Gut! Euer ganzer Körper
kam zum Einsatz!
¡Bien, la voz salía del cuerpo!
¡Bien, habéis sacado la voz del cuerpo!
Bien joué,
vos voix sortaient de vos corps !
Sì!
Isso! Vocês cantaram de corpo inteiro.
Ну вот, теперь вижу — 
пользуетесь всем, чем надо!
