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?

Tokise High School's koto club finished their performance. Despite the mistakes in the first half, they made a remarkable comeback in the second half. Now, they nervously await the results of the competition.

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 telling Takinami that she'd quit as a koto teacher, Akira goes to the club room to find that something is different with the koto club members' sound. During the practice, Takinami stops by and asks Akira and Satowa to play together.

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.

Satowa confronts her mother and everyone waits for the results of the competition.
