Upon reaching Verdanturf Town, the heroes encounter Drew, who is unable to compete in the upcoming Contest because his Roselia was defeated by the Phantom and his Dusclops. May, taken aback, decides to focus on her own training for the Contest. Suddenly, the Phantom shows up, prompting Ash to challenge him to a battle. Before they can engage, a woman appears and attempts to chase the Phantom but is unsuccessful. Eager to uncover the Phantom's true identity, she asks the heroes for their help in revealing who he really is.
