"Murder Case No. 30" As the public buzzes over the issuance of the new 10,000 yen banknote featuring the "Toto Tower" design, Conan and the Junior Detective League, along with Professor Agasa, Ran, and Sonoko, visit the Nagano factory of the Japan Banknote Printing Bureau. Meanwhile, at the Metropolitan Police Department, Superintendent Kuroda, Megure, Sato, Takagi, and other members of the First Investigation Division, as well as Kazami Yuya and other members of the Public Security Department, are gathered. Document appraisal technician Satomi Touko determines that the new 10,000 yen banknote found in a murder case that Sato and Takagi were investigating is a counterfeit, and an investigation headquarters is established. As this counterfeit is the 30th counterfeit banknote found in Japan, the case is nicknamed "Case No. 30," and the counterfeit banknote is named "Ultra 30." As the public is thrown into chaos by the unprecedented news of counterfeit new banknotes circulating, Conan and Heiji head to the Osaka factory where the counterfeit banknotes are believed to have been printed. Meanwhile, investigations are also being launched into banknote factories outside of Osaka. At the banknote factory on the border of Shizuoka and Kanagawa prefectures, Shizuoka Prefectural Police officer Yokomizo Sango and Kanagawa Prefectural Police officer Yokomizo Shigeo gather, while at the banknote factory on the border of Nagano and Gunma prefectures, where Ran and the others are located, Nagano Prefectural Police officers Yamato Kansuke, Morofushi Takaaki, and Uehara Yui, along with Gunma Prefectural Police officer Yamamura Misao, are assembled. A national crisis stemming from the counterfeiting of new banknotes is tackled by the largest all-star cast in Conan history!
