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!

I'll put in a good word for you 
so you can go back to conducting.
فسأوصي بك كي تستطيع 
العودة لقيادة الأوركسترا
werde ich dein Comeback
als Kapellmeister in die Wege leiten.
eu mexo meus pauzinhos para colocar
você de volta no mundo das orquestras.
я дам тебе рекомендацию, 
и тебя возьмут обратно в дирижёры.
