As Noise confronts the Cures, he reveals he was created from the sorrow of humans. Hibiki senses that Noise is suffering himself, refusing to fight against him. As Noise attempts to absorb Hibiki, Hummy jumps inside him with the Legendary Score and sings a newly written melody in a bid to purify the Notes within him, encouraging the girls to transform and fight again and try to reach Noise's feelings. As the girls desire to see Noise smile and Hummy's determination peak, the Fairy Tones combine into a new Crescendo Tone, which grants the Cures Crescendo forms. Together the girls manage to combine their powers and purify Noise, who smiles before disappearing.
