At Osaka's Takaramachi Jewelry Museum, a billion-yen jewel sits locked behind glass and security measures designed to stop anyone foolish enough to try. Then Kid the Phantom Thief makes his move, and Conan Edogawa realizes this particular heist carries far more danger than usual. A mysterious sniper has arrived with intentions of their own, turning what should be a straightforward cat-and-mouse game between detective and thief into a three-way standoff with lives on the line. Conan must balance stopping Kid's theft while uncovering who the sniper really is and what they actually want. The clock ticks down through August 15th as the museum becomes a powder keg of competing agendas. Between Kid's clever misdirection, the sniper's calculated precision, and Conan's deductive prowess, this clash demands something different from the usual mystery formula. The result is a high-stakes heist where trust becomes currency, alliances shift moment to moment, and nobody can be certain who's hunting whom.
