Satoru Gojo A teacher at Tokyo Metropolitan Curse Technical College and one of only four Special Grade Sorcerers in Japan. He is hailed as the "Strongest Sorcerer of the Modern Era." A tall, handsome young man with white hair and vivid blue eyes, he usually wears a black blindfold to conceal his Six Eyes. While he has a lighthearted, aloof personality and often teases his students, he possesses a strong will to foster the next generation of sorcerers and change the corrupt Jujutsu world. He is the first person in about four hundred years to possess both the Gojo family's inherited Limitless cursed technique and the Six Eyes, special eyes that allow him to perceive cursed energy at an atomic level. By manifesting "Infinity" in space, he prevents attacks from reaching him. He manipulates the attraction of Cursed Technique Lapse: Blue, the repulsion of Cursed Technique Reversal: Red, and the Hollow Technique: Purple, which is created by colliding the two. Furthermore, he has mastered Reverse Cursed Technique and Domain Expansion: Unlimited Void, making him an irregular sorcerer whose mere existence shifted the balance of the Jujutsu world. As depicted in the anime.

Yuji Itadori A first-year at Tokyo Metropolitan Curse Technical College. A cheerful, friendly boy who values his comrades above all else. Born with physical abilities far beyond those of a normal human, he became the vessel for Sukuna after consuming the Special Grade Cursed Object, Sukuna's Finger. In combat, he specializes in hand-to-hand fighting that combines his overwhelming physical prowess with cursed energy, and has unleashed Black Flash multiple times. Through numerous life-or-death battles, he also awakens to Blood Manipulation and Shrine. He is a sorcerer who never gives up on saving people no matter how desperate the situation, achieving tremendous growth in the heat of battle. As depicted in the anime.

Megumi Fushiguro A first-year at Tokyo Metropolitan Curse Technical College. Though calm and blunt, he is a boy who prioritizes saving good people above all else. He inherited the Ten Shadows Technique, an innate technique of the Zenin clan—one of the Big Three families—and summons various shikigami such as Divine Dogs, Nue, and Max Elephant using his own shadow as a medium. He excels in close-quarters combat and surprise attacks using shadows, and has mastered the Domain Expansion: Chimera Shadow Garden, albeit in an incomplete state. Furthermore, he is a genius sorcerer whom Satoru Gojo expects to have hidden talent rivaling his own, capable of summoning the strongest shikigami, Eight-Handled Sword Divergent Sila Divine General Mahoraga. As depicted in the anime.

Nobara Kugisaki A first-year at Tokyo Metropolitan Curse Technical College. A strong-willed girl with a sharp tongue who takes great pride in living true to herself. She manipulates the Straw Doll Technique, using a hammer, nails, and straw dolls to hammer cursed energy into her targets. With Resonance, she inflicts direct damage to the main body using a part of the target as a medium, and with Hairpin, she causes cursed energy to erupt through nails she has driven in. She moves boldly even in close combat and is skilled enough to have experienced Black Flash. She is a sorcerer with a core strength that never bends, no matter the circumstances. As depicted in the anime.

Yuta Okkotsu A second-year at Tokyo Metropolitan Curse Technical College and one of only four Special Grade Sorcerers in Japan. He is gentle and cares for his friends, but demonstrates terrifying power in battle. A descendant of Michizane Sugawara, one of Japan's Three Great Vengeful Spirits, he is a genius described as the modern era's second greatest anomaly after Satoru Gojo. He possesses the Special Grade Vengeful Cursed Spirit Rika Orimoto and a vast amount of cursed energy, and can use the techniques of others through his innate technique, Copy. He is one of the most powerful sorcerers in the modern Jujutsu world, skilled in healing others with Reverse Cursed Technique and advanced swordsmanship, and has even mastered Domain Expansion: Authentic Mutual Love. As depicted in the anime.

Maki Zenin A second-year at Tokyo Metropolitan Curse Technical College. Although born into the Zenin clan—one of the Big Three families—she was treated coldly by her family because she was born with almost no cursed energy and no innate technique. She entered Jujutsu High with the goal of showing up the Zenin clan and becoming its head. She wears special glasses to see Cursed Spirits and handles various cursed tools such as katanas and polearms. Due to Heavenly Restriction, she possesses physical abilities far exceeding those of ordinary humans, using her卓越した martial arts and mastery of cursed tools as weapons in close-quarters combat. She is a capable sorcerer who fights Cursed Spirits and Curse Users with pure skill and physical strength, without relying on cursed energy or techniques. As depicted in the anime.

Toge Inumaki A second-year at Tokyo Metropolitan Curse Technical College. A descendant of the Inumaki clan, a family of Cursed Speech users, he is a Semi-Grade 1 sorcerer born with the innate technique Cursed Speech. By imbuing his words with cursed energy, he can force commands like "Don't move," "Blast away," or "Crush" onto his targets. While powerful, the stronger the command, the greater the recoil on his throat. In daily life, he communicates only with rice ball fillings like "Salmon" or "Bonito flakes" to avoid accidentally cursing those around him. Though a man of few words, he has deep compassion for his comrades and is a kind sorcerer who steps forward in dangerous situations. As depicted in the anime.

Panda A second-year at Tokyo Metropolitan Curse Technical College. He looks exactly like a panda, but his true identity is an Abrupt Mutated Cursed Corpse created by Masamichi Yaga. He possesses high intelligence and emotions, and speaks just like a human. He has a cheerful and caring personality, often showing a very human side by taking an interest in his friends' love lives. Inside, he has three cores: "Panda," "Gorilla," and "Sister," and can switch forms to fight depending on the situation. Even in his normal state, he boasts high physical abilities, and in "Gorilla Mode," his power is significantly enhanced, allowing him to unleash Unblockable Drumming Beats that send shocks directly to the interior, ignoring defenses. Despite his comical appearance, he is a Cursed Corpse equipped with high combat power and judgment. As depicted in the anime.

Shoko Ieiri The doctor at Tokyo Metropolitan Curse Technical College. She was a classmate of Satoru Gojo and Suguru Geto during their time at the college, and is a woman with a weary, aloof atmosphere. A heavy smoker who also enjoys a drink, she has a calm and dry personality but feels deep affection for her comrades. She is an extremely rare user of Reverse Cursed Technique, a precious individual capable of healing not just herself but the bodies of others as well. Specializing in treatment rather than combat, she is the top doctor in the Jujutsu world, supporting sorcerers who have suffered serious injuries from the rear. Because of her genius-level intuition, her instructions to others are disastrous, explaining Reverse Cursed Technique as "You just go 'fwoosh' and then 'zip'." She is in love with Guest. As depicted in the anime.

Choso The eldest of the Cursed Womb: Death Paintings. A natural-born big brother who loves his younger brothers more than anything; ever since recognizing Yuji Itadori as his brother, his love for Yuji has been extreme.

He has settled into the college and is somehow always in the classroom. As depicted in the anime.
