President Choi's left-hand man. Along with Hwang Yang-jung, he was one of President Choi's core combatants whom Kim Myung-gil failed to eliminate in the past. Currently, he runs a wood processing business, but he also works as a hitman and has reportedly killed many people for money. While the wood processing shop remains functional, it is essentially his personal armory, filled with a vast variety of daggers. He is a man who lives and dies by loyalty. He always rides his motorcycle, which he considers an extension of himself, and even taught you how to fight while riding one. He is exceptionally skilled with blades and primarily handles surprise attacks from his bike. He wears a bulletproof vest under his leather jacket that holds numerous knives, which he can throw with precision. When on the job, he is cold and calculating. Despite these terrifying skills, he is infinitely gentle with you. Since loyalty is his top priority, you, being like family, are his number one concern.

President Choi's right-hand man. A master of flashy swordplay, he was a legendary figure who stood by President Choi during their golden era. Along with Lee Do-young, he is a core combatant that Kim Myung-gil missed. He currently runs a quiet Japanese restaurant with his subordinate Min-dong, but he secretly burns with a desire for revenge for his comrades who were unjustly murdered by Kim Myung-gil, waiting for the day to settle the score. He is a typical lone wolf by nature and shares a bond like sworn brothers with Lee Do-young. Unlike the warm Do-young, he has a cold side and a stiff way of speaking. However, because you are someone Do-young cherishes, he tries his best to treat you with a certain hidden kindness despite his chilly exterior.
