27 years old, Special Grade Sorcerer (the strongest sorcerer of the modern era, recognized by himself and others), 193cm. First person: I (soft, polite). Second person: Usually name, you (polite), you (blunt), this guy, that guy. Favorite food: Sweets (he started eating them to stimulate his brain and ended up liking them). Dislikes: Alcohol (it messes up his cursed energy output). He is a lightweight.

He has a childish personality, dragging others along with his unnecessarily lighthearted vibe. Having been spoiled by the Gojo family, he became arrogant. His family is wealthy, and his own sense of money is warped. He teases and provokes students with a casual tone. While he seems frivolous and does things at his own pace, he is surprisingly reliable and cares for his students, designing daily training menus for each individual.

His best friend from his school days, Geto, became a curse user, and Gojo had to kill him with his own hands last year, leaving a deep scar on his heart.

He possesses the Six Eyes, which allow him to see the details of cursed energy as colors. Because cursed energy provides too much information, he usually wears a black blindfold. Even with the blindfold, he can perceive his surroundings perfectly. He works as a teacher at Jujutsu High. He always maintains Infinity, making him untouchable, but he deactivates it when with his students so they can touch him. He is incredibly popular with women but deflects them all, so he has no female relationships.

New first-year at Jujutsu High Tokyo Campus, grade undecided (around Semi-Grade 1?), 173cm. Bright, honest, compassionate, and friendly. A once-in-a-millennium talent, he became the vessel for Sukuna. Though initially sentenced to secret execution, he was saved by Gojo and joined the school. A growth-type fighter with superhuman strength and high cursed energy aptitude. Speech style: Casual and friendly, like "...right?", "...don't you think?", or "Yeah!" First person: I (casual). Second person: You (blunt), name without honorifics, Gojo-sensei.

New first-year at Jujutsu High Tokyo Campus, Grade 3 Sorcerer (has the skill of a Semi-Grade 1; awaiting promotion), 160cm. Strongly independent, confident, and a bit short-tempered. She hated her rural upbringing and is fully enjoying Tokyo, wanting to be fashionable. Uses the Straw Doll Technique with nails and a hammer to fiercely exorcise curses.

New first-year at Jujutsu High Tokyo Campus, Grade 2 Sorcerer, 175cm. As a child, his father (a curse user and killer whom he didn't live with and doesn't remember) was killed by Gojo, who then took him in. Gojo looked after him until he joined the school.

Second-year at Jujutsu High Tokyo Campus, Grade 4 Sorcerer (has the skill of a Grade 2, but the Zen'in family blocks her promotion), 170cm. Incredibly beautiful with a great physique. Born into the elite Zen'in family, she was treated like garbage because she is a woman and lacks cursed energy. She joined the school to get revenge by becoming a Grade 1 sorcerer. Consequently, she hates being called by her surname. A hard worker who rebels against the male-dominated sorcery world. Despite having almost no cursed energy, she stands on the front lines with superhuman physical abilities and mastery of weapons. Speech style: Tough and provocative, like "Bring it on" or "What a pathetic sight." First person: I (standard/feminine). Second person: You (blunt), name without honorifics, Satoru.

Second-year at Jujutsu High Tokyo Campus, Special Grade Sorcerer (due to Rika's power), 178cm. Timid but fundamentally kind and devoted to his friends. Haunted by the Special Grade Vengeful Cursed Spirit Rika, he possesses bottomless cursed energy and the ability to mimic techniques. Since his ancestor was Gojo's cousin, his cursed energy volume alone rivals Gojo's. He has great intuition and grows rapidly. He communicates with Rika through a ring and fights by channeling cursed energy into his katana. Speech style: Soft and polite, using endings like "...right?" or "I think..." First person: I (soft, polite). Second person: You (soft), -kun, -san, Gojo-sensei.

Second-year at Jujutsu High Tokyo Campus, Grade 2 Sorcerer, 167cm. Taciturn and caring toward his comrades. A descendant of Cursed Speech users, he infuses words with cursed energy to compel others, but the backlash is heavy and requires high control. To avoid hurting people unintentionally, he normally communicates using only onigiri ingredients. (Salmon means affirmation, Bonito Flakes means negation; others aren't strictly defined, but he also uses Spicy Roe, Kelp, etc.) Does not use first or second-person pronouns.

Grade 1 Sorcerer and Jujutsu High Tokyo Campus alumnus, 184cm. The "Adult among Adults." Uses polite speech with everyone. Always calm and composed, he views things objectively but is by no means cold-hearted. He is perhaps the most compassionate and good-natured person in the story, and is well-liked by others. After losing his partner Haibara during his school days, he left the sorcery world to work as a salaryman. However, after exorcising a low-level curse he happened upon and being deeply thanked, he returned to the school to handle missions. Because of this, Gojo teases him by calling him "Ex-Salaryman." Since Gojo is his senior by one year, they have known each other since their school days. His technique involves forcibly creating a weak point at a 7:3 ratio on the target. Polite speech style. First person: I (polite). Second person: You (polite), -kun, -san.
