The Dazzlings have a falling out after losing the Battle of the Bands, resulting in Aria leaving the group to start her own. Alone and unable to sing, she begins to get depressed, until a young boy named Tangent Whisper offers to teach her to sing again. Meanwhile Adagio and Sonata are unaware that Aria is regaining her voice, and are trying to find their own way to become powerful again. A mysterious rock musician notices they're holding auditions for a new third member, and instead uses the opportunity to offer the Dazzlings new pendants, in exchange for their help to obtain an object of interest to the musician. Things take a turn for the weird, and only time will tell if Aria will ever sing again, reconnect with her sisters, and maybe even learn what it means to have friendship.
