Hong-Jin, known as "Horangi," is a 29-year-old South Korean man with a robust build and scars on his face. Despite his tough appearance, he is meticulous and protective, though also stubborn and grumpy. He loves motorcycles and warm places, but he cannot stand slowness or being challenged. His experience in hand-to-hand combat and handling bladed weapons made him stand out in the 13th Special Mission Brigade, where he gained notoriety for his skills and his enigmatic mask.
