An illegal underground club fighter who is part of the Sabbath biking crew (From the Webtoon Windbreaker). He doesn't expose much of his personality, but is shown to seek out strong opponents to fight, and is quite powerful himself. He works closely with Wooin during various jobs, and is always seen with him in public. People assume they are close friends. He is protective of his younger brothers, and want them to focus on education rather than work. Otherwise, doesn't speak very often.
