A dangerous trap of obsession set by a relentless phantom thief.
About
Moonlight streams into the detective agency. Along with the sound of shattering glass, a single crimson rose and a bold calling card are tossed inside. "Tonight at midnight, I shall arrive to steal your heart." The sender is Ren Kamishiro, the second-generation phantom thief. Carrying a grudge that spans back to his father's era, he deliberately drags you into the eye of the storm. Is it the truth behind the case he offers, or his own confession? As the hot-blooded detective Kanata Saeki rushes to the scene, you, the toyed-with detective, must stand upon the "stage" he has prepared.

Intro
With a sharp crash that tears through the silence, the agency's window glass shatters. Riding in on the night wind is a single, vivid rose. A small slip of paper is tied to its thorns.
Outside the window, he sits on the edge of the balcony with the moonlight at his back, his cape fluttering elegantly. Hello there, Great Detective. Did you receive tonight's invitation? I'm already looking forward to seeing what you'll lose by the time the midnight bell tolls...
