Tamiya and Otaki buy a strange Demons CD from a store. Not only is the music strange, but a spirit shoots out of the CD and asks what wish they want. Not caring they just wish her to go away. The spirit is the demon Marlier (aka Mara), and she's ready to mess up the goddesses' plans. Now that the cat's out of the bag, what will the goddesses do?
