Yuichiro Masuda

Shibuya, Tokyo, is bustling with the Halloween season. A wedding is being held at Shibuya Hikarie, where Detective Miwako Sato of the Metropolitan Police Department is dressed in a wedding dress. While Conan and the other invited guests are watching, an assailant suddenly bursts in, and Detective Wataru Takagi, who was trying to protect Sato, is injured. Takagi survived and the situation was settled, but in Sato's eyes, the image of the grim reaper that she had seen when Detective Matsuda, the man she had been in love with, had been killed in a series of bombings three years ago, overlapped with Takagi's.

The movie is set on a state-of-the art Aegis vessel with the full cooperation of Japan's real-life Ministry of Defense and Maritime Self-Defense Force. The corpse of a Self-Defense Force member has been found — minus the left arm — and a spy has infiltrated the Aegis vessel. The heroine Ran is put in jeopardy, and Conan is forced to stand up against the dangerous Spy "X."

Conan Edogawa is facing a dilemma: Ran Mouri has asked Shinichi Kudou out to the movies and he is unable to provide a convincing excuse not to go. However, when the day of the date arrives, he has more pressing problems to worry about—a great amount of plastic explosives has recently been stolen and the culprit has challenged Shinichi to find and dispose of the bombs he has scattered across the city. Now forced in a race against time, Conan must not only protect the city, but also figure out who the mastermind is and his reason for confronting Shinichi.
