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!

Boys! I'm over here!

¡Chicos, estoy aquí!
¡Chicos, estoy aquí!
Les garçons,
Ehi, voi.
Gente! Eu estou aqui!
Ребята, я тут!
