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!

Okay, let's have you sing 
to see if you're any good or not.
حسناً، فلتغنّوا لنرى ما إن كنتم صالحين أم لا
Dann zeigt mir mal,
ob ihr zu irgendwas gut seid.
Canten para que pueda evaluar
si sirven o no.
A ver, cantad para ver si valéis.
J’ai besoin de savoir
si vous êtes utiles, chantez.
Allora,
Enfim, não sei se vai dar pra
aproveitar, mas vamos lá!
Ладно, пойте. 
Поймём, стоите вы чего-то или нет.
