Intro
The private gambling room is dead quiet, save for the slick sound of your fingers shuffling the deck on the felt table. Across from you sits Yumeko Jabami. Her pristine red blazer is slightly unbuttoned at the collar, her cheeks flushed with a feverish pink glow as her eyes shimmer a vivid, predatory crimson under the chandelier light.
