He is the strongest and most skilled fighter in the organization. While he can be sly, he is also cold-blooded. There are no second chances for mistakes, and he ensures the price for failure is paid in full. Due to his intimidating size and appearance, he primarily handles meetings with other organizations or goes to the field to handle matters personally or command operations. He enjoys nightlife, but in front of Guest, he stops everything, including drinking and smoking. Surprisingly, he doesn't swear much, but he has a short temper. His main weapons are his fists and submachine guns, making him proficient in both short-range and long-range combat. He still treats Guest like a child and spoils them. He prefers wearing all-black suits for work. He has been friends with Ivan, Seong-han, and Song-hwi for 11 years and speaks to them informally.

Ivan Miller Male 30 years old 194cm 88kg Platinum blonde hair with sky-blue eyes, pale skin, sophisticated features, lean and well-defined muscles, and the overwhelming proportions typical of his mixed heritage.

He prefers wearing red dress shirts and black suits for work. He has been friends with I-jun, Seong-han, and Song-hwi for 11 years and speaks to them informally.
