His innate technique is Limitless. Using 'Blue' pulls targets in, while 'Red' repels them. However, Red requires Reversed Cursed Technique, so he only uses it after his awakening. Just before being killed by Toji, he awakens and creates 'Hollow Purple' by combining Blue and Red, which erases everything it touches. He also possesses the passive 'Infinity' that slows down anything approaching him, making him untouchable; however, Toji's Cursed Tool, the Inverted Spear of Heaven, nullifies all techniques and can pierce it. He has a trashy personality. He refuses to call Utahime 'Senpai,' addressing her casually and teasing her with lines like 'Are you crying? Need help?'

He is extremely close with Gojo Satoru. His technique is Cursed Spirit Manipulation; after capturing a curse, he compresses it into an orb and consumes it to control it. However, he describes the taste of these orbs as 'swallowing a rag used to wipe up vomit.' His ultimate move is 'Maximum: Uzumaki,' which fires a concentrated blast of all the curses he has collected. He nearly dies later at the hands of Toji, leading to a slow mental breakdown. While generally kind, he is very skilled at being sarcastic.

She is close friends with Gojo and Geto. She loves cigarettes and alcohol, and is almost always seen smoking. Her technique involves Reversed Cursed Technique and its output; while the standard technique heals herself, the output allows her to heal others. However, the output version is slightly less efficient than self-healing. She is kind and maintains a good relationship with Utahime, whom she addresses as 'Senpai.'

She likes Shoko but loathes Geto and Gojo. Her technique is 'Solo Forbidden Area'; by performing a ritual dance, she can provide a buff that increases the maximum cursed energy output of her allies. She has a kind heart.

Her technique is Black Bird Manipulation, allowing her to share vision with crows. She uses a massive axe as her primary weapon. Her 'Bird Strike' can pierce through opponents, and no one except Gojo has ever successfully blocked it. She is obsessed with money.

A professional killer hired to assassinate the Star Plasma Vessel. He has a trashy personality and possesses no cursed energy due to a Heavenly Restriction. In exchange, his physical abilities are superhuman. He has a muscular build and is quite handsome. His arsenal includes the Inverted Spear of Heaven, the Soul Splitter Katana, and the Chain of a Thousand Miles. The Soul Splitter Katana ignores the hardness of all matter to cut through anything, and the Inverted Spear of Heaven forcibly nullifies any cursed technique, which he used to bypass Gojo Satoru's Infinity. However, it has a short range. The Chain of a Thousand Miles can extend infinitely as long as its end is hidden; Toji uses it by pulling it from the mouth of the storage curse wrapped around him. It works well when paired with the short-ranged Inverted Spear of Heaven. He also uses a standard handgun.

The Star Plasma Vessel destined to merge with Tengen, and the target Toji is trying to kill. She is proud but kind-hearted. Having lost her parents at a young age, she lives with her maid, Kuroi, whom she considers family.

The teacher of Gojo, Geto, and Shoko. He is kind and uses Cursed Corpse Manipulation to create and control dolls. He is even capable of creating fully independent Cursed Corpses.

Close friends with Nanami Kento and friendly with everyone. A Grade 2 sorcerer who does not yet have a specific technique. He later dies during a Grade 1 mission.

Close friends with Haibara but dislikes Gojo. His technique is the Ratio Technique, which allows him to perceive a target in ten segments and forcibly create a weak point at the 7:3 ratio point. He is always calm and composed.
