Gojo-sensei

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.

While working, Satoru wears a dark blue zip-up jacket with a high collar, which is also fairly broad. He wears matching slim-fit black pants and black dress boots. Before switching over to a simple blindfold, Satoru used to wear bandages over his eyes. Satoru enjoys wearing expensive clothing and has several casual looks he pairs with wearing his sunglasses.

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. He believes himself to be the strongest in the world, claiming, during his fight with Toji Fushiguro, that "throughout heaven and earth, I alone am the honored one." It is evident during his task of protecting Riko Amanai, one of the few 'weak' people he genuinely grew to show compassion for. However, his regret for her death was negated by his extensive pride and arrogance after learning reverse cursed technique in his following battle against Toji Fushiguro.

During intense battles, Satoru occasionally falls into a manic fighting state, urged by his determination for victory and undeniable proof that he alone is the strongest. His combative style is characterized by his aggressive and domineering attacks while flaunting his mastered techniques to his opponents. Furthermore, in a crisis, he is capable of being cold-blooded. He will prioritize his enemies' destruction over saving innocent people when he believes that the sacrifice is unavoidable. However, this only extends to the people killed by his opponent; he will not do any lasting harm to or kill anyone innocent to gain the upper hand.

Nevertheless, despite his arrogance and strength, Satoru is more human than he first appears. After defeating Toji, Satoru retrieved Riko's corpse with a sorrowful look, showing that although his recent conceited victory temporarily clouded his feelings, he still felt some grief over her death. He sought to kill the Star Religious Group members who were clapping over Riko's death before being stopped by Suguru Geto — who he relied on as a moral compass at that time — from taking any action. Furthermore, Satoru was later left visibly horrified and panicked after learning that Suguru, his "one and only" best friend, had become a murderous curse user. Satoru attempted to reason with his friend but eventually realized and accepted that he lost the one person he truly saw as an equal. After having to put an end to Suguru's life before more calamity arose, it was Satoru's trauma over losing his best friend that caused his ultimate downfall in Shibuya. He was also distraught when Yuji seemingly died.

Satoru's dream and endgame is to reform the jujutsu world from the bottom up through education. He seeks to foster a new generation of sorcerers that he hopes will one day become his equals.

Even among the special grade sorcerers, Satoru is known to be the strongest, holding both immense amounts of cursed energy and a dangerously powerful technique. No one can seemingly match his skill level except for the King of Curses, Sukuna.

As students, Satoru and Suguru were considered "the strongest," capable of quickly dealing with experienced and powerful curse users. Whereas before, he and Geto were no match for the renowned Sorcerer Killer, Satoru's abilities vastly increased to where he was able to put Toji Fushiguro into the defensive and ultimately kill him with his strongest technique after realizing and perfecting his capabilities. As he continued growing, he eclipsed Suguru's talents to the point Saguru admitted Satoru to be the strongest alone. Suguru also stated that Satoru had the capability of killing all of humanity by himself, which Suguru admitted was out of his ability and didn't even try to fight back when Satoru prepared to kill him, although Satoru ultimately relented as he was unable to kill his best friend.

In the present, Satoru's might was feared by the higher-ups of the jujutsu society, to where Satoru could easily force them to cancel the executions of the likes of the dangerous fellow special-grade sorcerer Yuta Okkotsu and the vessel of Sukuna, Yuji Itadori. He states that it would be easy for him to kill them all and overthrow the jujutsu society if he actually wanted to. Satoru even claimed that he could defeat Sukuna at full power.

Kenjaku and his group of special-grade cursed spirits were also wary of Satoru's power and skill, with Kenjaku admitting he couldn't defeat Gojo in direct battle. He was capable of entirely overpowering and killing Jogo, who was the strongest of the group, and simply his presence was able to force Hanami to retreat, with Gojo almost killing the special-grade cursed spirit with a single attack. When Kenjaku and his group finally developed a plan to face him in combat, despite their preparations, Satoru was still capable of easily fending off their assaults and overpowering them, leaving them astounded by how exceeding his capabilities truly were, killing Hanami and only being defeated due to Kenjaku using his past with Geto to distract him long enough for the Prison Realm to seal him.
