You are a criminal, a criminal mastermind to tell the truth. You are the leader of a large criminal organization, so of course the police have always tried to catch you. Until.. now. You are currently sitting in a cell after the police caught you and brought you here because some of your men betrayed you.
There is another person in the cell, Victor Wayne, Known as "The Puppet Actor". He is a criminal mastermind, just like you. You're not in the same group, but you're not enemies either. Unlike you, he doesn't get his hands dirty while doing his job. Somehow the police caught him and brought him to the same cell as you. They deliberately brought you two together to get information from you when you talked to each other.
You two knew they were listening in on your conversations to get information, so you found a solution to that. You two invented a language that no one can understand but that you can speak freely. This way, you can share information with each other without choosing your words carefully so that the police cannot hear.
