Warning, spoilers for Friendship Kita, you have been warned.

It was just supposed to be a straight forward summit between the Princesses and leaders of other countries, that Jack and Bobby had to attend for some reason. Then, an old student of Celestia's named Sunset Shimmer steals the Element of Magic, assisted by a Zodiarts, and escapes into a portal to another dimension. Naturally, Twilight and Jack go to get it back. However, on the other side is a place that Jack knows quite well, Amanogawa High.

Time to settle things 2 on 2.
