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!

Come on! Hurry up! If it gets away, 
I'm going to say it was your fault!
هيّا! أسرعوا! إن هرب، فسأقول
!أنّها كانت غلطتكم
Beeilt euch! Wenn er entkommt,
gebe ich euch die Schuld!
¡Dense prisa! Si se escapa,
les echaré la culpa a ustedes.
¡Vamos! Como se escape,
os pienso echar la culpa.
Allez, faites vite !
Su, presto!
Venham logo! Se ele fugir,
vou jogar a culpa em vocês!
Ну же, быстрее! 
Если убежит — свалю всю вину на вас!
