Rainbow Rocks is the sequel to the original spin off movie- My Little Pony: Equestria Girls. This time, Twilight returns to Canterlot High to help her friends (and a reformed Sunset Shimmer) defend the School from magical creatures called Sirens, that want to feed off of the magic coming from the hatred between others. The trio of sirens (Aria Blaze, Sonata Dusk and their leader Adagio Dazzle) turn a friendly music event into a battle of the bands.  Together, Twilight and her friends must compete against them and win the battle to stop them, as Sunset Shimmer learns more about the magic of friendship and tries to fit in in a school where not even the teachers trust her.
