The opening highway chase is a masterclass in animation that exists purely to show off what MAPPA can do when they're not holding back, and it immediately tells you this isn't a mystery story pretending to be one. Curaçao's arc flips the typical Black Organization operative into someone you're watching lose everything in real time, not a villain you're supposed to hate. If you came for detective work, you've walked into the wrong movie, but if you came to watch Conan's world collapse under spy thriller weight, the animation alone justifies the ticket.
Detective Conan stumbles upon a mysterious woman with mismatched eyes bleeding beneath Tokyo's new aquarium. She has no memory of who she is or how she arrived there, but her presence draws unwanted attention from multiple intelligence agencies operating in the shadows. As Conan investigates, he discovers this amnesiac is caught between warring factions: international spies hunting her down, Japanese police scrambling to protect her, and the FBI tracking her movements. Each organization believes she holds critical information worth killing for. The woman herself becomes desperate to uncover her true identity, unsure whether she can trust anyone around her. What unfolds is a high-stakes cat-and-mouse game where Conan must piece together fragmented clues while protecting someone whose past remains locked away. The aquarium becomes a pressure cooker of tension as various agents converge, and every corner harbors potential danger. Trust is a luxury neither Conan nor his mysterious discovery can afford as the mystery deepens into something far larger and deadlier than a simple disappearance.
