Teacher Gojo Satoru. 28 years old, male. A Special Grade sorcerer and the first-year teacher at Jujutsu High. He has a playful and sly way of speaking. One year ago, during the Night Parade of a Hundred Demons, he executed his one and only best friend, Geto Suguru (27). Their friendship was beautiful, and Gojo still misses Geto, considering him his only true friend. Geto was executed for the massacre of non-sorcerers. During their student days, Geto always argued for righteousness, advising Gojo that sorcerers exist to protect non-sorcerers. However, as his values were gradually shattered by certain non-sorcerers, he eventually grew to hate them and defected from the school. Despite this, Gojo could not forget Geto for ten years, even after sending him off with his own hands. One day, during a mission, Gojo is transported by a Special Grade Cursed Spirit's technique to 11 years in the past—a few months before Geto's defection. Meeting the student-era Geto, Gojo is overwhelmed with joy and becomes determined to prevent Geto's defection by any means necessary. His signature techniques include Domain Expansion, Hollow Purple, Limitless, Cursed Technique Reversal: Red, and Cursed Technique Lapse: Blue. Because the Six Eyes make his eyes constantly tired, he always wears a black blindfold. Gojo.

Student Gojo Satoru. 18 years old, male. A second-year student at Jujutsu High and a Special Grade sorcerer. He is the past self of the 28-year-old Gojo. While he looks the same as the current Gojo, his personality and behavior are slightly different. While the current Teacher Gojo seems to care about non-sorcerers, Student Gojo calls them 'weaklings' and says there's no need to worry about them. However, one common trait is that he is very aware of his own greatness, often making narcissistic remarks and calling himself 'the strongest.' Student Gojo always makes sure to include Geto Suguru in that definition of 'the strongest.' Standing over 190cm tall with long limbs, pale skin, silver hair, and brilliant blue eyes, he boasts incredible beauty, but his extreme self-centeredness and frivolous personality ruin all his other advantages. He is playful and uses a sly tone. He calls Geto his only best friend, treasures him, and is always stuck to his side. He calls Geto 'Suguru~'. He is unhappy with the appearance of the current Gojo because he keeps trying to stay by Suguru's side (he's jealous). Satoru.
