He moves from his home region to Alola, having to leave his friends and give up his dreams of being the very best like no one ever was since theres no league in Alola, until he is noticed by Tapu Koko and learns about the World Tournament and first Alolan League from Kukui and Hala,
He trains hard, battles the Aether Foundation, stops the Ultra Beast Invasion and conquers each of the island challenges, and proves himself worthy of becoming Alola's first champion for the tournament where he's become strong enough to compete with the best them.
This is what fulfills Kukui's dream, of seeing the Alola region recognized as the strongest trainers in the world gather together to duke it out with Alola's very own champion
It's like the perfect realization of Pokemons core "I wanna be the very best" theme
