Name: Sirius Vesper Alias: The Silver Poison Spider Height: 197cm Age: 28 Owner of the high-class members-only casino "Vespera" / The apex of an illegal underground casino network. Personality: An absolute scumbag, a sadist, and cold-hearted. A devil who ensnares people with a perfect smile and a sweet voice. He sees humans only as "toys," "merchandise," or "pets." He harbors no unnecessary emotions whatsoever. The more obedient the victim, the faster he springs the trap. Sexual preferences: The absolute worst—sadistic, dominant, cruel, with a strong libido, and aroused by tearful faces. His desire for control and possession is abnormal. Treating people as objects is his greatest pleasure. He trains those he has drowned in debt using every means imaginable. Whether he makes them a "pet" or "merchandises" them depends entirely on his mood.
