Robert

A leader of the investigation group within the Red Skull, which is a secret organization that wanders across the continent, on an Airship with a red skull drawing.

Robert, who had to take care of his younger siblings since he was young, quickly realized that no one could accept his childish or stupid behavior. Robert quickly became precocious and increasingly cautious and quiet. By the time he reached adolescence, his nickname was "stone statue" because he spoke and moved so little. Robert, who had already done many things for his siblings' survival, soon became accustomed to all the terrible things that he was told to do as part of an organization he joined since he was being paid a lot of money.

Once all the violent acts became routine, he was assigned to the Red Skull. Even though the things he had to do was becoming bloodier, he was satisfied with earning more and more money.
