Suddenly, a howling noise rang through the city, and when it died down, all music was gone. Ako and Mephisto tried to establish contact with Major Land, but could not get a response. Full of worry, Hibiki and the others headed to Major Land, where there was no sign of the former land of overflowing music.

And as the truth slowly came to light, the Pretty Cure had to face up to the real enemy.
