As both Aphrodite and Mephisto contemplate going to the Human World, Hummy detects a large number of Notes around and orders Hibiki and Kanade to help catch them, despite the fact they can't see them themselves. Hummy soon helps make the Notes visible and the gang compete with each other to catch the most Notes. Meanwhile, Siren and the Minor Trio have their own Note-catching contest to decide who the leader will be. The two sides soon clash and a Negatone battle ensues, with Hibiki and Kanade getting pinned. However, they are saved when Otokichi plays the Melody of Happiness, allowing them to break free and defeat the Negatone. Afterwards, Cure Muse releases the Notes she recovered from the Minor gang, whilst Aphrodite and Mephisto change their minds.
