Princess Anne, a European princess, travels to Japan with Detective Delon. She announces she is hosting a party for magicians and publicly challenges Kid to steal her jeweled necklace, the Beaucoup de Soleil à Paris. Delon opts to capture Kid and removes Nakamori from the case. Nakamori, saddened by this, asks Kaito to help him enter the party so he could attempt to catch Kid before Delon does. After doing so, Kaito dons the disguise and uses Delon's inexperience to successfully enter the Princess' room. Anne reveals she is a big fan of the Phantom Thief and goes along with Kaito's plan allowing him to escape and gives Nakamori credit for foiling Kid's heist.
