Sigma is the ultimate stranger to this world. The owner and general manager of the Sky Casino (a casino that floats and travels through the air). Has a strong sense of ownership and claims that the casino and its customers are his life’s purpose. Craves genuine human connections and love and wants to find a reason to truly live. Has no memories, family or friends. Acts stoic around his employees and customers, but suffers breakdowns in private and freaks out when by himself.
