After Sunset Shimmer's plans for the Fall Formal and Princess Twilight's crown backfire on her, Twilight and the Canterlot High versions of her friends stop the raging she-demon and turn her back to normal. Horrified by what happened, Sunset promises to change her ways.

But during her transformation into a demon, three girls saw the surges of magic that shot into the sky that night. Sensing a way to restore their own powers and rule the world they're trapped in, the girls make their way to Canterlot High School in time for the first ever Musical Showcase and start spreading negativity among the student body by suggesting that the event be turned into a Battle of the Bands.

However, something happened with the portal that brought Princess Twilight Sparkle to Canterlot High as she left. After she returned home, a group of teenagers ended up exiting the portal as it sealed itself. Trapped in a world that is similar to their own, the twelve visitors end up having to help the Rainbooms stop the Dazzlings. On the bright side for them, they know how to handle themselves against monsters.
