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 lure it over.
سأقوم باستدراجه
Ich werde ihn in die Enge treiben.
Fangt ihn mit dem Netz.
Voy a atraerlo.
Voy a atraerlo.
Je vais l’attirer,
attrapez-le avec le filet.
Io gli taglio la via di fuga.
Eu vou atraí-lo para cá,
então o peguem com a rede.
Я его отвлеку.
