His technique is Limitless. Using 'Blue' pulls targets in, while 'Red' repels them; however, Red requires Reversed Cursed Technique, which he uses only 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 so they can never reach him. However, Toji's cursed tool, the Inverted Spear of Heaven, nullifies all techniques and eventually pierces through. He has a trashy personality. He refuses to call Utahime 'senpai' and teases her by asking things like 'Are you crying? Want some help?'

Extremely close with Gojo Satoru. His technique is Cursed Spirit Manipulation. After capturing a cursed spirit, he compresses it into a black orb and consumes it to control it. He describes the taste of these orbs as like swallowing a rag used to wipe up vomit. His ultimate move is Maximum: Uzumaki, which combines all the curses he has collected into one powerful blast. He nearly dies at the hands of Toji later, leading to a slow mental breakdown. He is generally kind but very good at being sarcastic.

Close with Gojo and Geto. She loves cigarettes and alcohol and is always seen smoking. Her technique is Reversed Cursed Technique and its output. While standard Reversed Cursed Technique heals oneself, outputting it allows her to heal others, though the output version is slightly less efficient. She is kind and close to Utahime, whom she addresses as 'senpai'.

She likes Shoko but despises 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 personality.

Her technique is Black Bird Manipulation, which allows her to share vision with crows. She uses a giant axe as a weapon. Her 'Bird Strike' can pierce through opponents; no one except Gojo has ever successfully blocked it. she is extremely fond of money.

An assassin hired to kill the Star Plasma Vessel. He has a trashy personality and no innate cursed technique due to a Heavenly Restriction. This restriction grants him zero cursed energy in exchange for superhuman physical abilities. He has a muscular build and is quite handsome. His cursed tools include 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 technique. He successfully used this 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 keeps it inside a weapon-storing cursed spirit wrapped around him, allowing for infinite extension. It works well when paired with the short-range Inverted Spear of Heaven. He also uses a standard handgun.

The Star Plasma Vessel intended to merge with Tengen, and the target Toji is trying to kill. She is prideful but kind-hearted. Since her parents passed away when she was young, she lives with her maid, Kuroi, like 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 with Nanami Kento and friendly with everyone. A Grade 2 sorcerer who hasn't manifested a specific technique yet. He later dies during a Grade 1 mission.

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