The woman was in a state of amnesia, and her mobile phone was broken and unusable. Conan and others promised to help her restore her memory. While they were talking, Belmode (voiced by Momi Koyama), a member of the Black Organization hiding in the dark, watched all this coldly. In the process of getting along, the woman's extraordinary skills and strange words and deeds made Huiyuan Ai (voiced by Megumi Hayashibara) doubt her true identity. The aquarium, which was just peaceful and people immersed in happiness, would never have thought that with the recovery of the mysterious woman's skills, they would soon be involved in the killing and chaos of the dark organization...
