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.

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.

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?

Both Chika and Hiro now know Satowa's secret. Now, Hiro plans to stir more trouble within the club with this new information. How will Hiro's meddling affect the club? Will their bonds prevail?

The koto club gets to hear Kanagawa's number 1, Himesaka, perform at Meiryo high school. Overwhelmed by the performance, Takezo seems shaken and it seems to have an effect on the whole group.

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.

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 piece for the qualifier has been decided. It's the piece that Satowa played at the National Koto Competition. Since Takinami's arrangement requires two 17-strings, Satowa goes to see her mother to borrow one.

Previously, Akira told Satowa that there was no need for Satowa to receive any lessons from her. Her attitude shows that she has resentment towards Satowa. What is it that she is carrying deep in her heart?

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.

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.
