Siren decides to leave the Minor Trio, prompting Hummy to recount their shared past. She reveals how Siren once helped her during a singing contest when other fairies attempted a trick, allowing Hummy to sing the Melody of Happiness. Moved by these words of friendship, Siren instead creates a Negatone from a music sheet that corners Hibiki and Kanade. Cure Muse appears again to encourage the pair to defeat the entity. Following the battle, Hibiki, Kanade, and Hummy must find a way to convince Siren to return to her good self.
