Battle of the Bands! The Sirens of Equestria have shown up at Canterlot High School after detecting the massive burst of Equestrian magic released during the Fall Formal, and have reduced the school once more to bickering and infighting using their own dark magical powers.

However Sunset Shimmer, pariah of the school after the events of the Fall Formal, the Rainbooms, and Princess Twilight rally together to save not only the school, but potentially the world!

Now is when we join in, as Sunset Shimmer is somehow compelled to track down the Sirens, for reasons she doesn't understand yet.

Mostly follows the canon for Equestria Girls and Rainbow Rocks, up until the end~
