In "Magic File 4: The Osaka Okonomiyaki Odyssey," Ran Mouri makes a brief appearance via a phone call to Conan Edogawa. She informs him that their departure from Osaka must be moved up by thirty minutes due to Sonoko Suzuki's error in the planned schedule. This call forces Conan to leave immediately, preventing him from sharing the okonomiyaki meal Heiji Hattori and Kazuha Toyama intended for him.
