The day of the qualifier for nationals has finally come. Seeing other students upon their arrival at the venue, the Tokise koto club members realize that they're all there seriously aiming to go to nationals.

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.

Himesaka Girls' Academy gave a powerful performance. Now it's time for Hakuto High School to take the stage. Will they give a performance that's the "right answer"? Or will it be different this time?

"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.
