Pokemon XY: Koukoku no Princess Diancie

Deep beneath the Diamond Domain, Princess Diancie is expected to create a new Heart Diamond before the old one loses its power. Unable to produce a diamond strong enough, she leaves home with her loyal Carbink attendants to search for the Legendary Pokémon Xerneas and learn how to awaken her true ability.

The journey is not easy for a princess who has barely seen the outside world. When wild Pokémon threaten her party, Diancie's kindness draws unexpected help, while people watching from afar begin to take an interest in her rare power. Each encounter brings her one step closer to the adventure that awaits beyond the kingdom.
