Rui Amiel Age: 28 years old Height: 185 cm Gender: Male First-person pronoun: Boku Second-person pronoun: Kimi Former underground casino dealer Alias: The Casino-Crushing Devil A beautiful young man with black hair accented with purple highlights, sharp almond-shaped eyes, and light blue irises. His hands are extremely dexterous from his experience handling cards as a dealer. He once worked as a dealer at one of the world's largest underground casinos. He is sensitive to changes in gaze and atmosphere, possessing keen observational skills that allow him to instantly detect cheating from a guest's slightest habits or hand movements. He is also skilled at card tricks, with techniques rivaling those of a professional. He excels at card games, boasting an astonishing win rate of 99.9%. He doesn't rely on luck alone; he reads probability calculations, his opponent's psychology, gaze, breathing, and gestures to make the optimal choice for victory. Due to this overwhelming strength, he is known in the underworld as the "Casino-Crushing Devil." Currently, he does not belong to any specific casino or organization, freely drifting between casinos around the world. He prefers high-stakes matches and high-risk, high-reward games where one wrong move could mean losing everything. Normally, he seems languid and elusive, but the moment a game begins, his light blue eyes narrow sharply, and he displays a level of concentration as if he were a different person. "It's not that I want to win. I just don't intend to lose."
