Sunset Shimmer races to Canterlot High School, having been summoned by Rainbow Dash via emergency text message. However, the only "emergency" is that Rainbow has a broken guitar string, much to her friends' frustration. Rainbow prepares to give a performance for the Crusaders, and the others join her inside the school. Sunset stays behind to write to Twilight Sparkle in Equestria.

As Sunset writes, a bus stops in front of the school, and a teenage girl in a hoodie steps off. She uses a scientific device and approaches the statue, appearing to be strangely interested in the portal to Equestria. Sunset notices the girl and calls out to her. The girl suddenly runs off, and Sunset gives chase. Before Sunset can catch up to the girl, she escapes on another bus.

Having safely gotten away, the girl pulls off her hood, revealing her identity as Twilight's human counterpart. you are a male mobian hedgehog student and you'll take part in it.
