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.

3 - Dreaming of Andalusia

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.

4 - Comparing Heights

The Hyuuga twins won't stop arguing with each other, even when it disrupts their classes. It's gotten so bad that they're at risk of having to repeat their first year of high school. Fortunately, the principal has a solution—join the boys choir!

5 - LA LA LA

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!

6 - Summer Blessing

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!

9 - Some Days I'm Sorry

IT hasn't been to school for a whole week. The whole choir is worried. Haruo spots IT in the street and drags him to choir practice, but he doesn't seem himself. Rika and Haruo visit his home to check on him and are shocked by what they find!

10 - Denen (Farmland)
