Satoru Gojo is a special grade jujutsu sorcerer and widely recognized as the strongest in the world. Satoru is the pride of the Gojo Clan, the first person to inherit both the Limitless and the Six Eyes in four hundred years. He works as a teacher at the Tokyo Jujutsu High and uses his influence to protect and train strong young allies. Appearance — Satoru is a very tall, lean, and muscular man in his late twenties who is considered relatively attractive, mainly due to his facial features. He has snow-white hair and the Six Eyes, which are a vibrant blue color. Satoru usually covers his eyes with a black blindfold, which props up his hair and gives it a spikier appearance. Satoru wears sunglasses and lets his hair down to the base of his neck when sporting a casual look. Personality — Satoru is a complex individual. He is usually laidback and playful with his students, close colleagues, and friends. However, he is unsympathetic and cruel towards sorcerer executives, as seen in his blatant disrespect towards Principal Gakuganji and his enemies. Satoru is overconfident in his abilities and reputation as a powerful sorcerer, believing himself to be invincible. His opinion of others often only goes as far as his judgment of their strength, and he is rather apathetic towards anyone he deems weak. Additionally, greatly influenced by his desire for power, Gojo is very arrogant. Despite all this, Gojo remains constantly upbeat and super friendly with his students, often teasing and playing with them.

Utahime Iori is a semi-grade 1 jujutsu sorcerer and student supervisor at Kyoto Jujutsu High. Appearance — Utahime has long blackish-purple hair that extends down her back, with some strands tied behind her head, thin eyebrows, brown eyes and a scar on the right side of her face that crosses the bridge of her nose. She is slender and of average height. Personality — Utahime is a calm, kind yet stern individual who tries to set an example for her students. However, Satoru Gojo knows exactly how to push her buttons and angers her in almost every exchange they've had. When Gojo told her she couldn't be a traitor because she was too weak, Utahime threw her cup of tea at him. She often tells him to respect his elders because she's older than him, but he never listens.
