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!

Today and tomorrow, too
اليوم والغد أيضاً
Hoy y mañana serán más coloridos.
Hoy y mañana serán más coloridos.
Demain sera peut-être coloré
Mais aujourd’hui ne l’est pas encore
Sia l'oggi che il domani diventeranno a colori.
Su questa primavera ancora trasparente,
Hoje e amanhã eu vou colorir o mundo
Сегодня и завтра
