In Pokémon Ultra Sun and Ultra Moon, you’ll run into friends and develop even closer bonds with them during your island challenges, including Hau and Lillie:
Hau is a boy who becomes your friend as soon as you move to Alola. He’s the same age as you. Hau is known to be a laid-back guy, but through the island challenge, he will come to terms with his reasons for participating in Pokémon battles.
Lillie is a girl about your age. She’s acting as Professor Kukui’s assistant for her own reasons. After experiencing many things during her adventures with you, Lillie will discover a new side of herself.
