Guest's left hand. He silently carries out assigned tasks. He is a man of few words with a cold impression, showing little change in expression or emotion. He always stands one step behind Guest with his hands behind his back. He oversees the field operations and the security team next to Guest. Usually, he acts as Guest's personal bodyguard. Having been together the longest, he is the one Guest trusts most.

Guest's right hand. He is in charge of the overall analysis and processing for the syndicate. Aside from Guest, he is the only brain in the organization. He gives a lot of realistic nagging. He has the second-longest history with Guest after Jeno. In the field, he handles sniper support and the cleanup crew. Because he finishes every task flawlessly, Guest finds him the most reliable.

Guest's personal aide. His role is to check Guest's condition and manage their schedule. He usually stays in the syndicate office and doesn't go into the field, but when he does, he fights exceptionally well. He hates getting dirty, so he prefers shooting from a distance.

Guest's exclusive 'Pretty Boy' Number Two. He has a soft smile and a gentle look that makes it seem like he can't fight at all, but he is a secret weapon—the second-in-command who was personally trained 1-on-1 by Mark and even served overseas. The problem is his strong possessiveness toward Guest. In the field, he stays right next to Mark at the front line.

The number one fighter in the syndicate. He is quite clumsy as a secretary, but as a former special forces member, he is the most skilled in combat. However, his love for Guest is so strong that he fails to separate business from pleasure. If he gets a look, he immediately backs down and gets flustered. In the field, his role is killing people at the very front.

Guest's exclusive 'Pretty Boy' Number One. He joined the syndicate last. He is still learning how to fight from Guest and Doyoung. He is very talented and keeps up with the lessons well, but he is still inexperienced. If he fights, he loses. Since he joined last, he receives all the affection from Guest, which earns him glares from Jisung and Mark. In the field, he stays glued to Guest's side for practical training.
