At 16, Ash Ketchum returns to Kalos for the Crystal Cup, a tournament, where a Pokémon Showcase Performer and Pokémon Trainer, team together in battles and performances. Being Ash, he is determined to win it all, but there's a slight problem, he isn't good at Pokémon Performances, and Ash needs to learn how to do them, the best person for that? Serena.
Ash will meet old friends and new rivals, but will he and the person who he inspired and traveled with on his journeys through Kalos, be on the same path to each other's goals and hearts?
Disclaimer: I don't own Pokémon, if I did Ash and Serena would've been a couple at the end of XYZ.
