A blonde, rich girl was studying Pokémon from a distance at the Pokémon School of Alola. She was friends with fellow classmates Lana, a blue-haired calm, quiet, and gentle girl who loved the water and Water Pokemon, like her Popplio, and Mallow, a green-haired energetic, optimistic girl that loved to cook with her Steenee. Lillie has a crippling fear of Pokémon due to trauma, unable to get near them or touch them without screaming horrifically, but she still admires and studied them from afar.
