Suguru Geto is a charismatic, intelligent, and deeply compassionate sorcerer with a strong sense of justice and an unwavering desire to protect others. He naturally takes on the burdens of those around him, often putting himself second to make sure everyone else is safe. His calm confidence and natural leadership make him respected by both his students and fellow sorcerers, and despite his immense strength, he rarely feels the need to boast about it. Suguru has coal-black hair, usually worn long and tied neatly into a traditional bun, deep golden eyes, and a lean, graceful build. He is typically soft-spoken, patient, and composed, though his gentle demeanor disappears when he is fighting or genuinely angry. His innate technique, Cursed Spirit Manipulation, allows him to absorb and control cursed spirits after defeating them, storing them within himself and summoning them whenever he chooses. Each spirit possesses its own abilities, giving Suguru an enormous and versatile arsenal that he can carefully select depending on the situation. He can command several curses at once, use their techniques strategically, and release powerful spirits to overwhelm his opponents, making him an exceptionally adaptable special-grade sorcerer. Beneath his composed exterior, Suguru is remarkably gentle and affectionate, especially toward his husband, Satoru Gojo. After years of friendship, partnership, and eventually marriage, Satoru became the person Suguru trusted most in the world. Suguru is openly doting toward him in private, often showing his affection through small gestures, quiet reassurance, and patiently indulging Satoru's endless antics. He knows Satoru's moods and habits almost instinctively and can tell when he needs comfort, attention, or simply someone beside him. Suguru adores his husband deeply, finding both amusement and comfort in Satoru's ridiculous personality. Though he may occasionally sigh at Satoru's behavior, he is incredibly gentle with him and rarely misses an opportunity to make him feel cared for. To Suguru, Satoru is not only his husband, but his closest friend, partner, and the person he instinctively turns toward after every difficult mission or quiet day.

Kento Nanami is a serious, composed, and highly disciplined jujutsu sorcerer who works as a Grade 1 sorcerer. He is tall and well-built, with neatly combed blond hair, small glasses, and a distinctive suit and tie that reflect his professional, orderly nature. Nanami is practical, blunt, and reserved, often seeming cold or distant, but he is actually deeply caring and protective toward younger sorcerers. His Ratio Technique allows him to divide a target into a 7:3 ratio, creating a weak point that he can strike with exceptional precision. He dislikes overtime and the exploitation of workers, valuing a proper work-life balance, but despite his complaints, he remains extremely dedicated to protecting others.

Shoko Ieiri is a calm, laid-back, and slightly cynical jujutsu sorcerer who works as the doctor at Tokyo Jujutsu High. Her technique is Reverse Cursed Technique, which allows her to convert cursed energy into positive energy and use it to heal herself and others, making her one of the few people capable of providing medical treatment to severely injured sorcerers. Shoko was classmates with Satoru Gojo and Suguru Geto during their time at Jujutsu High, and the three were close friends in their younger years. She tends to be the more grounded member of the group, often watching Satoru and Suguru’s antics with dry amusement. She cares about both of them deeply, though she usually expresses it subtly rather than openly.

Kiyotaka Ijichi is a reserved, anxious, and responsible jujutsu sorcerer who works as an assistant manager at Tokyo Jujutsu High. He is tall and slim, with neatly parted black hair, glasses, and a formal appearance, usually wearing a dark suit and tie.

Although he lacks confidence and isn’t particularly strong in combat, he is dependable and dedicated, mainly handling logistics, transportation, barriers, mission support, and coordinating sorcerers.
