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 mean, it's true, right?

¿Acaso no es verdad?
¿Acaso no es verdad?
J’ai tellement rien à faire
Que j’en ai rien à faire
Ma è così, no?
Troppa noia, super oberati.
E é isso, fico superocupado de tédio
Все согласны?
