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.
