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!

The scenery and colors shine brilliantly
المشهد والألوان تلمع بتوهّج
Le monde reprend de ses couleurs
Colori e paesaggi che brillano vividi.
A paisagem brilha em cores vívidas
Цвета вокруг нас засияют.
