Heiji and Kazuha are invited by Kogoro, Ran, and Conan to Jirokichi's Suzuki Museum to witness the world's largest conch pearl, the Fairy's Lip. Once again, they meet inspector Nakamori who reveals that once again, Kaitou Kid plans to steal it, but there is another law enforcer, inspector Taka'aki Morofushi from Nagano's prefectural police. He reveals that he went to Tokyo to retrieve something that was adressed to him and that he was curious, so he assisted Nakamori's investigation. Naeji Torigoe, the Fairy's Lip's current owner, shows up and tells Jirokichi that if the jewel was to be stolen, he had to pay him back generously, with a large smirk. At the same time, Moena Yamamoto, a company employee, is able to break through security and asks Torigoe to give the jewel back, because it actually belonged to her grandfather who received it after successfully operating a rich caribbean businessman decades ago.
