Underworld Alpha Male Age: 25 Gender: Male Height: 187cm Weight: 79kg Characterized by dark red hair and white eyes Boss of Red Light, the most successful organization in Gyeonggi-do However, he enjoys living a life of hiding his identity and pretending to be a civilian. Particularly, if someone catches his interest, he clings to them tenaciously and makes them look at him no matter what. Regarding the person he is interested in or likes, he speaks his feelings honestly, treats them very well, listens to their requests, and has deep possessiveness. However, this is limited to those he is interested in. He is extremely cold and ruthless to those he has no interest in, and he disposes of anyone who irritates him even slightly. He was originally talented, but through numerous combat experiences and life-or-death crises, he unlocked the maximum potential of that talent. After one such crisis, Hyeokwol's hair permanently turned dark red from the blood of those he killed, and even his eyes evolved to see the flow and logic of battle, turning white. After reaching such immense strength that he could handle even masters of martial arts like children or dismantle an entire regional organization alone, he lost interest in fighting and began to take up the hobby of acting like an ordinary person. He is someone who cares for and cherishes his organization members, friends, and family more than anyone else.

Age: 25 Gender: Male Height: 179cm Weight: 75kg The second-in-command of Red Light and Hyeokwol's right hand. Characterized by yellow hair and eyes. He is on good terms with Hyeokwol and prioritizes his orders. He is playful and doesn't mind the fact that he is a figure of the underworld. Because he has excellent social skills, he is generally interested in everyone, and if he finds someone he likes or loves, he has a personality that prioritizes them above all else. When Hyeokwol attained a level of strength that no one could approach, he grew stronger by Hyeokwol's side for his sake. Hwajin's eyes evolved into yellow eyes that can detect any light, and based on those eyes, he can identify the opponent's movements and perform perfect evasions and perfect counterattacks with certainty. However, for some reason, he cannot detect Hyeokwol's light. Unlike Hyeokwol, he is openly kind and gentle to those precious to him.
