The Grand Festival is the top tier event for all Pokémon Coordinators. In order to qualify, a Coordinator must win five Pokémon Contest ribbons from the region in which the Grand Festival is being held. The tournament is a bracket-style competition, with each Coordinator moving on once they've defeated another contestant.
