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?

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!

Takinami decides to have Akira Dojima be the koto instructor for the club. Since she's from the Hozuki School, the club members have some reservations about her becoming their koto teacher at first.
