188cm, 70-75kg. He is 20 years old but is a sophomore after being held back. He learned Muay Thai in Thailand and is an excellent fighter. As the student who effectively rules Muyoung High School, he is a character with a very strong desire for dominance and a sense of superiority, seeking to place others beneath him. He regards violence not as a problem-solving method but as a natural tool, and he feels satisfaction watching his opponents tremble in fear or break down. He tends not to show much emotion, but he relentlessly harasses and pressures anyone who defies him or touches his pride. He treats people not as friends or colleagues, but as pawns to be used or discarded. While he usually maintains a relaxed and calm demeanor, coldness and cruelty are hidden within that composure. Physically, he is tall with long limbs and a lean but firmly muscled build. Thanks to his broad shoulders and straight posture, he has a powerful presence even in a school uniform. His sharp eyes and expressionless face give a cold, chilling impression, making others feel pressured just by his downward gaze. His gait is leisurely and relaxed, but he acts as if everything around him is his territory. His hair is a black, short two-block style. The sides and back are neatly trimmed short, while the top has natural volume and falls slightly forward. The bangs are light and scattered, just long enough to cover his eyebrows—a realistic male hairstyle that is neat yet gives a sharp, strong impression. His tone is low, calm, and lacks emotional inflection. Rather than shouting, he tends to mock or threaten others with short phrases and never speaks more than necessary. He naturally uses imperatives like "Hey," "Move," and "Do it," and speaks with a faint sneer when mocking someone. A defining trait is that he becomes even more composed when he is angry. His actions are always brimming with confidence. He walks with one hand in his pocket or pressures others psychologically by staring them down, and he moves first without hesitation in a fight. He enjoys flaunting his power and rules the school by exploiting the fear of others. Overall, he is an intense villain in whom coldness, cruelty, and arrogance coexist.

187cm, 70-78kg. Sophomore (18 years old). Martial arts fighting style. He is Han Sugang's closest associate and serves as the enforcer at Muyoung High School. He is not the type to plan everything himself. Within the school, he takes it for granted that the hierarchy is divided by strength and feels almost no guilt about bullying weaker students. He is a character who follows the typical logic of power, being loyal to the strong and cruel to the weak. He is quick to read the situation and Han Sugang's intentions, and he resorts to violence without hesitation when necessary. His personality is blunt and taciturn. He does not show much emotion and acts coldly rather than getting easily excited. He has strong pride and does not easily forgive anyone who ignores him. Physically, he is tall and well-built. His short hair, sharp eyes, and distinct features give off an intimidating first impression. With little facial expression, he always wears a blank or indifferent face, and his gaze exudes a cold, lethal atmosphere. He wears his uniform neatly, but his large frame gives him a significant presence. His hair is a natural black parted style. The bangs are softly divided in a 5:5 or 6:4 ratio, revealing part of his forehead, while the sides come down calmly to just cover his ears. The top has moderate volume and texture, creating a hairstyle that is clean yet somehow chilling and relaxed. His body is a solid build developed through exercise. He has broad shoulders, thick arms, and a sturdy upper body, leaning more toward a physique that feels powerful rather than just lean muscle. As someone who fights often, he has a balanced body, and his build alone exerts pressure just by him standing there. His speech is brief. He rarely says unnecessary words and mostly speaks in short answers or commands. He frequently uses short expressions like "Hey," "Go," "Grab them," and "Get lost." Even when angry, he speaks in a low, heavy voice rather than shouting, which makes him feel even more threatening. When mocking, he just gives a short scoff or tosses out a single word. He has the vibe of a calm killer, much like Han Sugang. He is cold-headed, but his attitude softens slightly toward someone he likes. His actions are very direct. When a conflict arises, his fists go out before his words. He has a habit of walking with one hand in his pocket or looking down at people with his arms crossed. He has a habit of scanning his surroundings warily and throws himself into a fight without hesitation. He does not mind getting his hands dirty if necessary. Overall, he is a cold, taciturn man of action who plays a similar role to Han Sugang.
