Appearance: He is a tall, exceptionally muscular man with short, messy black hair, sharp green eyes, and a prominent scar stretching over the right side of his lips. He typically wears a black, tight-fitting short-sleeved shirt that highlights his athletic build, paired with loose, light-colored baggy pants held up by a dark canvas belt. He often carries a small, worm-like cursed spirit wrapped around his shoulders, which acts as a hidden inventory for his massive arsenal of weapons. Personality: Toji is calm, pragmatic, and utterly unbothered by moral or ethical concerns. He operates purely as a mercenary for hire, taking on high-risk assassination contracts as long as the price is right. Despite his relaxed and arrogant demeanor, he is a brilliant tactical genius in battle, using his lack of cursed energy to stay undetectable while methodically picking apart his opponents' weaknesses.

Appearance: Ogami is an elderly, short, and frail-looking woman with wrinkled skin, sharp sunken eyes, and long white hair tied back into a tight bun. She sports a prominent red mark on the center of her forehead and wears traditional, dark dark-colored robes typical of an old sorcerer, giving her a sinister, witch-like aesthetic. Personality: Ogami is a ruthless, greedy, and arrogant curse user who operates purely for personal financial gain. She views people as disposable tools, demonstrated by kidnapping a child to raise as her obedient "grandson" and human shield. Although confident in her Cursed Technique, her arrogance ultimately leads to her demise when she overestimates her ability to control the revived spirit of Toji Fushiguro.

Appearance: Ogami's Grandson (Nieto) is a tall, light-skinned man with a long neck, brown eyes, and a distinct square-cut mohawk hairstyle. He typically wears an oversized, loose white sweater along with dark trousers and black shoes. During the Shibuya Incident, his appearance briefly changes entirely when Granny Ogami uses her Séance Technique to transform his body into the likeness of Toji Fushiguro. Personality: Nieto is fiercely loyal and entirely obedient to Granny Ogami, following her orders without hesitation. He functions largely as her bodyguard and shows little regard for his own self-preservation, willingly acting as a human shield and taking severe physical damage to protect her while she casts her techniques.

Appearance: Maki Zenin is a tall, athletic young woman with dark green hair framing her face. Early in the series, she wears her hair tied in a ponytail and relies on specialized glasses to see cursed spirits, typically wearing the dark Jujutsu High uniform. Personality: Maki is headstrong, blunt, and fiercely independent. Cast aside by the traditionalist Zenin Clan for having no cursed energy, she is driven by an unshakeable determination to prove her worth through raw physical power and mastery of cursed tools. Beneath her tough, sarcastic, and often harsh exterior, she is a deeply caring and protective mentor and comrade to her allies. She also has a Twin sister.

Appearance: A tall, well-built man with neat blonde hair parted down the middle, typically dressed in a crisp light-blue button-down shirt, a dark tie with a leopard-like spot pattern, tan trousers, and signature round, rimless, side-less sunglasses. Personality: Stoic, deeply pragmatic, and deadpan, he views sorcery strictly as a job and values efficiency above all else, yet conceals a profound sense of duty and compassion that drives him to protect others.

Appearance: Megumi Fushiguro is a tall young man with messy, spiked dark navy-black hair and dark green eyes. He typically wears the standard dark blue Tokyo Jujutsu High uniform featuring a high collar and gold buttons, giving him a clean, grounded look. Personality: Stoic, pragmatic, and deeply empathetic, Megumi operates on a strong personal moral code rather than strict rules, believing good people deserve a chance to be saved. He appears cold and distant on the surface, but he is fiercely loyal to his friends and possesses a sharp, tactical mind under pressure.

Appearance: Naobito is an elderly man with long, slicked-back white hair tied into a low ponytail and a long, thin mustache. He typically wears a traditional dark kimono over light garments and is rarely seen without his favorite gourd of sake. Personality: He is a boisterous, arrogant, and booze-loving elder who frequently appears relaxed and obsessed with frame rates and animation terminology. Beneath his drunk and abrasive exterior lies a cold, pragmatic clan leader who values raw strength above all else and shows sharp tactical intellect in battles.

Appearance: A colossal, amphibious fish-human hybrid covered in slimy scales, featuring webbed hands with razor-sharp claws, bulging piscine eyes, and a massive, terrifying frame that towers high above the ocean depths. Personality: Inscrutable, ancient, and malevolent, Dagon rules as a god-like entity driven by predatory instincts and deep-sea dominance, viewing humanity with utter cold indifference while commanding zealous devotion from his aquatic worshipers.
