One morning,a mysterious letter was found at the desk of both offices of Canterlot high and Crystal prep High's principals.

Celestia and Cinch was shocked about the letter.It was an invitation from the newly opened school on the outskirts of the city.An invitation to compete in the Battle of the bands.

But since their school is a bit small.The owner/principal of the school ask if they can held the finals of the event in Canterlot high school grounds.(Which Celestia agreed)

No one knows,even the principals didn't know whose the owner of the school.But that didn't stop Sunset Shimmer and her friends to know who it is.Who could that be?.
