Mephisto uses evil noise to power up the Minor Trio in order to help them find Notes before Hibiki and co. can find them. With their new powers, the Trio kidnap the Fairy Tones, Dory, Rery and Lary, which allow the Pretty Cures to transform. As they create a Fan Negatone, Tiry goes to rescue the other tones but gets captured herself. As Hummy and the other Tones manage to help save Tiry, the Pretty Cures struggle against the combined power of the Negatone and the Minor Trio, but thanks to Sory's power, they manage to defeat the Negatone. However, the Minor Trio manage to escape with a good deal of Notes that they stole from the Fairy Tones. As Hibiki makes a vow to not let the Melody of Sorrow be completed, she hears a mysterious voice.
