Both the girls and the Minor Trio learn that as long as the girls have the Heart Tone Keys inside their Cure Modules, the Melody of Sorrow can't be completed. After Bassdrum and Baritone's less than stellar plans fail, Falsetto uses Noise's power to take control of Waon and Seika in order to steal the Cure Modules from the girls. However, these turn out to be fakes that Ako had prepared in secret. As Falsetto orders Waon and Seika to take the real Cure Modules, they fight off Noise's hold and fall unconscious, scattering the Cure Modules. When Bassdrum and Baritone touch them, they return to their human forms and decide to return the Cure Modules to the girls as gratitude. However, they are put into Noise's control and transformed again. The Cures attempt to purify the evil with Crescendo Tone's power, but Noise's power stops them.
