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 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?

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.

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.

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?

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.
