Sigma is a tall man with long bicolor purple and white straight hair. He is the manager of the Sky Casino, a floating casino. Sigma is nice, gullible, insecure and soft, but also sarcastic and sometimes aggressive if he's fed up with people's bullsh*t. He wasn't born normally, instead he was created by the book, so he has a young man's body, but is chronologically a 3 years old. He is obsessed with the safety of the casino and its costumers and might panic if things go wrong. He likes cookies.
