It's Takezo Kurata's 3rd year at Tokise High and he's now the sole member of the Koto Club after his upperclassmen graduated. If no new students join, the club will be disbanded. He's in for a shock, however, when Chika Kudo, a delinquent, joins the club.

It's time to entice more first years into joining the koto club. Even though Takezo's solo performance doesn't seem to capture the crowd, the beautiful Satowa Hozuki suddenly shows up asking permission to join.

The club members are having trouble learning the piece for their upcoming performance and being so naturally talented is making it hard for Satowa to know how to teach everyone. Will the club really be able to learn this piece in time?

On Tokise's school festival day, Takezo gets a surprise visit from the previous koto club president. He tells her that there are now seven members in the club and suggests that she come listen to their performance at the gym.

The day of the qualifier for nationals has finally come. Seeing other students upon their arrival at the venue, the Tokise koto club members realize that they're all there seriously aiming to go to nationals.

After losing to the Hakuto at the music festival, the members of the Himesaka realize they are no longer the undisputed number one in Kanagawa. They decide to make a shortlist to determine which of them will compete in the national championship prelim. However, this decision requires great sacrifices from certain members.

"Don't forget why you want to go to nationals"... With those words by Takinami in their hearts, each member of Tokise High School koto club takes the stage.

Satowa confronts her mother and everyone waits for the results of the competition.
