Yo! That's Some Friendly You-nity!

As Sera has trouble understanding Sarasvati's fascination with Ayumu's rear, Haruna attempts to fix Mystelltain by herself, but it all comes to pieces when Ayumu tries to use it too early. Meanwhile, Haruna tries to help Yuki practice to be a backup dancer for Sarasvati's concert, only for the dance to turn out to be a curse. With Sarasvati threatening to send Yuki back to her village if she doesn't perfect the dance, Ayumu helps her get some last minute practise. Come the concert, the dance becomes a super curse that forces everyone to dance til they drop.
