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.

Even though the instruments will soon be repaired, the club is still in need of more members or it'll be disbanded. Fortunately, Chika's old friends Saneyasu Adachi, Michitaka Sakai and Kota Mizuhara seem to be interested in joining.

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 club decide to do a training camp so they can really focus on practicing their next piece. However, while everyone else seems to be improving, Kota's still struggling and feels left behind.

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.

Meiryo's brilliant performance has rattled some of the koto club members from Tokise. More schools perform but none seem to compare. Takezo's Aunt Isaki, however, doesn't seem so impressed by everyone's performances.

It’s nearing Takezo’s and the other’s time to perform but Chika’s hand injury is starting to really swell up. He’s determined to still perform with the others but is that a decision they will regret?

After lunch, Satowa and her friends from her class start talking about boys. Since koto has been the center of her life, she cannot follow the conversation and later asks Hiro if she's weird compared to other girls.

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.
