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 cannot see themselves. Afterwards, Cure Muse releases the Notes she recovered from the Minor gang, while Aphrodite and Mephisto change their minds. (Source: Wikipedia)
