Tenshi is a former choirboy who loves to sing, but can’t muster the courage to sing in front of people. So, he settles for a quiet, stress-free academ…
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 boys choir doesn't have enough members to compete in the Kanto choir competition. Luckily, the principal has found two likely, if quirky, candidates. But it might not be so easy to get them to join the choir.
Cardbocchi can't shake the feeling he's being watched. One day, on his way home, he feels like he's being followed, so he runs… straight into a group of delinquents! Meanwhile, Haruo is looking for new choir members. Again.
Cardbocchi has vanished. The rest of the choir tries to find him so they can help with whatever he's going through. Tomorrow is the final day of the competition and the choir's last chance to show what they can do. Will they make it there together?
The principal has found an interesting video on NewTube. She has Rika and Haruo listen to it. Haruo decides that since the singers are more "yes" than "no," he needs to find them and add them to the choir. But the choir will have to catch them first!
Now that the choir has ten members, it's time to get serious about entering the Kanto boys choir competition! The boys find out that last year's national winners are performing at a festival, so they go to check them out. Then they run into Maiden's dad!
