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?

It's almost time for the clubs big performance. They need to satisfy the whole school or the club will be disbanded! They're all nervous and the crowd seems displeased from the get-go. Can they do it?

A new member, Hiro Kurusu, has joined the koto club. She's a second year student from the same class as Takezo. He hasn't talked to her much but she seems nice. Will she get along with the members of the club?

Chika and the other club members are having trouble understanding Satowa's instruction. Later, 2 girls from the elite Himesaka Girls Academy randomly show up at the clubroom that seem to know Satowa!

The training camp has come to an end and the High School Students' Kanto Region Traditional Japanese Music Festival is finally around the corner. To the gang's surprise, the koto clubs from Meiryo and Himesaka are participating in the festival too.

The members of the koto club have started thinking about what Takinami said: the meaning and role of their sound. In the meantime, Dojima arranges a meeting with the senior members of the Hozuki School.

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.

"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.
