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.

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?

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?

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 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.

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?
