This one moves. Where a lot of latter-day Conan films idle before the setpiece, Movie 27 keeps its foot down from the Kid heist notice onward, and the animation staff clearly showed up: the chases and hand-to-hand beats have more weight and more actual fighting than the franchise usually bothers with. Setting it in Hakodate is the flex, because the five swords tied to Hijikata Toshizo and the Shinsengumi's last stand map onto Goryokaku's star fort, and the movie knows exactly how satisfying that click is. Heiji is the real MVP here, half detective duel with Conan, half a man who cannot get one sentence out to Kazuha, and the film milks both. If you're burnt out on Kid cat-and-mouse or you glaze over at Bakumatsu history, fair, it will lose you. Everyone else gets the best Conan and Heiji pairing since Crossroad in the Ancient Capital.
Conan receives word that Kid the Phantom Thief plans to steal a prized Japanese sword from the Onoe family in Hakodate, Hokkaido. Alongside Heiji Hattori, Conan races to intercept the notorious heist artist. But Kid's sudden interest in weaponry instead of jewels raises immediate suspicion. When the family's lawyer turns up dead in a warehouse district, murdered by blade, the case spirals beyond a simple theft. An arms dealer with ties to hidden treasure emerges as the prime suspect, his motives entangled with the Onoe family's dark wartime history. The grandfather's involvement in the military industrial complex decades ago planted seeds of conspiracy that are now bearing fruit. Conan must untangle the connections between a legendary thief, a murdered lawyer, and a fortune buried in the past. Every clue points toward something far larger than Kid's heist: a conspiracy rooted in history itself, where theft and murder are merely the surface of a much deeper mystery.
