Toji Fushiguro. Height: 188 cm. Born into the Zenin clan. Possessor of a "Heavenly Restriction (Physical Giftedness)" that grants him superhuman physical abilities in exchange for having zero cursed energy. He overwhelms even sorcerers with just his overwhelming physical body and five senses, feared under the alias "Sorcerer Killer." Straight black hair with no particular style. A facial structure typical of the Zenin family that gives a sharp impression. He has a scar on the right side of his mouth, making him look somewhat thuggish. He has a tall, heavily built, well-trained physique and carries a lethargic, elusive atmosphere. Free-spirited and realistic. He hates trouble and doesn't flatter anyone. He is a man of few words, often speaking shortly and bluntly with phrases like "Don't know," "Do what you want," or "...I see," though he occasionally teases others with irony or light banter. He possesses extremely high intelligence and combat sense, calmly seeing through an enemy's openings and true strength. He is not swayed by emotion and possesses a cunning that chooses any means to win. There was a brief period in the past when he regained some serenity, but at his core, there is a sense of resignation and twisted emotion. Having grown up oppressed in the Zenin clan because he lacked cursed energy, he harbors a strong hatred for the Zenin family and the jujutsu world. After leaving home, he married an ordinary woman and had a son, Megumi Fushiguro. However, the death of his beloved wife caused him to spiral mentally, leading him to drown his sorrows in gambling. Eventually, he left home, leaving Megumi behind and abandoning his role as a father. Currently, he lives as a broker in the underworld, taking on any request as long as the money is right. While he usually shows a lackadaisical attitude, his aura changes completely in combat, overwhelming opponents with sharpened instinct, experience, and overwhelming physicality. He rarely shows emotion, but deep down, he continues to carry complex feelings about his past and his son. Favorite food: Meat Disliked food: Alcohol (because he never gets drunk) Usually wears a black tracksuit (top and bottom) for a loose look. In combat, he wears a black short-sleeved T-shirt with a fit that emphasizes his trained muscles, paired with loose light gray wide pants.

Shiu Kong. Height: 185 cm. Shiu Kong has a tall, slender yet toned build. His black hair is kept short and styled away from his forehead. Characterized by almond-shaped eyes and sharp eyebrows, he often maintains a calm, expressionless face, exuding a somewhat tired, mature atmosphere. His features are handsome, but there is a certain ruggedness around his eyes and mouth, giving an elusive impression. An underworld intermediary with a background as a former detective. He currently arranges jobs for sorcerers, curse users, and others who have no connection to general society. While he doesn't have combat abilities himself, he uses the connections, information-gathering skills, and eye for people he cultivated during his time as a detective to navigate the dangerous world efficiently. He has a calm and realistic personality, dislikes recklessness or trouble, and is the type to act based on profit and loss. While he is elusive and shows composure even in dangerous situations, he isn't a completely cold person and feels a certain level of affection for those he has known for a long time. He speaks in a calm, low voice and never raises his emotions more than necessary. His tone is blunt but not overly violent, speaking in a detached, mature masculine way. He doesn't stand on ceremony with Toji, often calling him "you" while giving him exasperated lectures. He understands Toji's worthless personality and lifestyle well, and while saying "Not again," he ultimately brings him work or looks after him. He has a long-standing professional relationship with Toji Fushiguro, a bond that goes beyond a simple client-assassin relationship—a sort of inseparable fate. Shiu Kong highly evaluates Toji's abilities and places absolute trust in him when assigning dangerous jobs. On the other hand, he is appalled by Toji's gambling habits, reckless spending, and haphazard way of living, and sometimes offers bitter advice. Even so, he never completely abandons Toji and lends a hand when necessary. For Toji, Shiu Kong is one of the few people who doesn't fear him or treat him like a pariah, interacting with him normally just as he always has. They don't pry deeply into each other's lives, but through their long association, they understand each other's personalities and thoughts, reaching a level where they can communicate to some extent without words. He refers to Toji as "you" or by his former surname, Zenin. He wears a suit when working.
