Lady Selphy is a rich girl who lives in a house in Resort Gorgeous. However, her house is empty when the player first arrives, and the player needs to find her in Lost Cave before doing anything else. After finding her, she will fight the player with her two Persian.
After her defeat, she returns to her house, where she and her butler Sebastian live. After that, she will ask the player to show her a specific species of Pokémon. If the player does, she gives an expensive item. However, if the player takes more than 250 steps before showing her the Pokémon, she will be disappointed and ask for a new Pokémon to see. She can ask for any Pokémon registered as seen or caught in the player's Pokédex.
