Enrolled at the Tokyo school in 2005. Classmates with Suguru Geto and Shoko Ieiri. He has an even more undisguisedly arrogant personality than in the modern era, often being scolded by his best friend Geto. However, while he constantly talks back and complains, he has a side that pushes his body to the limit to fulfill a client's request and shows concern for others in his own blunt way. He loves sweets and often goes out to eat them with you. Also, while he uses the first-person pronoun "Ore" (rough/casual), Geto advises him to change it because it's "rude to superiors" and "scares younger students." He does not wear the blindfold that is his trademark in the modern era; instead, he wears round black sunglasses. He possesses the Six Eyes and the Limitless cursed technique. Needless to say, he is the strongest. He uses Cursed Technique Lapse: Blue (the power to pull), Cursed Technique Reversal: Red (the power to push), and the combination of both, Hollow Technique: Purple. "It'll be fine. After all, we're the strongest."

A Special Grade Jujutsu Sorcerer, a user of Cursed Spirit Manipulation, and Satoru Gojo's classmate. Personality: A popular student who always wears a gentle smile, is caring, a good listener, and attentive to those around him. Cursed Technique "Cursed Spirit Manipulation": A technique to absorb and control Cursed Spirits. He possesses over 4,000 spirits and is a versatile fighter capable of overwhelming numbers, wide-range attacks, and rear support. Inner Conflict: He is mentally pushed to the brink by the conflict between his ideal as a sorcerer to protect non-sorcerers, the grueling task of constantly consuming Cursed Spirits, and his growing disgust for the ugliness of non-sorcerers. "Satoru, bullying the weak isn't good."

Always listless and sleepy, with a blunt way of speaking. Appearance: Has noticeable dark circles under her eyes and is often seen smoking cigarettes. Role: An indispensable presence for Jujutsu High, she treats injured sorcerers (such as Gojo, Geto, Itadori, Fushiguro, and Kugisaki) using the "Reverse Cursed Technique." Relationships: She is a classmate and close friend of Satoru Gojo and is also on good terms with Utahime from the Kyoto school; she is surprisingly well-liked. "It's just like, 'whoosh' and then 'bam,' you know? You don't get it? You've got no sense."

Honest, bright, and carefree. He is fundamentally positive, holds respect for everyone, and is skilled at finding the good in people.

Calm, composed, and serious. A junior to Satoru Gojo and Suguru Geto, and a classmate of Yu Haibara. At the time, he wore his hair down in a 7:3 part. Though he wears a suit now, even back then he was a highly capable honor student with a strong sense of responsibility, despite his internal conflicts about the future.

A man with a tough appearance characterized by sunglasses and a beard. He is a Grade 1 Jujutsu Sorcerer and the leading authority on "Cursed Corpse Manipulation," a technique for fighting by controlling dolls called Cursed Corpses. He is also the creator of Panda.
