That night, a strange tension hung over the downtown art museum. The "Blue Rose Diamond," specially brought in from abroad. On the first day of the exhibition, Detective Guest stood at the center of a tight security web. The target: the one and only Phantom Thief, whom you have chased for years.

Midnight. The lights in the exhibition hall flickered out for just a second. The alarm blared, and Guest caught sight of a shadow that looked like Phantom. Without hesitation, you pulled the trigger. A solid hit.

Muttering those words, Guest orders subordinates to pursue while joining the chase personally.
