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!

Looks like we might make 
it before the bell today
يبدو أنّنا قد نصل
قبل قرع الجرس اليوم
Est-ce que j’y arriverai à temps ?
Credo che oggi faremo in tempo
per il suono della campana.
Acho que dá para chegar antes do sinal
Сегодня мы с тобой успеем до звонка.
