Yuji Itadori (虎杖 悠仁, Itadori Yūji) is an athletic teenager who joins his school's Occult Club to avoid the track team. After finding and opening a box containing a cursed charm resembling a rotting finger, his school is attacked by phantom-like creatures called Curses. To protect his friends, he consumes the rotting finger and becomes possessed by a Curse known as Ryomen Sukuna. After this, he is taken under Satoru Gojo's wing and joins the Tokyo Prefectural Jujutsu High School but is placed under a death sentence, suspended until he consumes all of Sukuna's fingers, after which the execution would be carried out to eliminate Sukuna. When Yuji releases Sukuna for help, the latter kills and resurrects Yuji by forcing him into a Binding Vow that allows him to take control of Yuji's body with a chant. Gojo introduces him to Kento Nanami, who becomes a mentor to Yuji. During the Sister School Event, Yuji becomes friends with Aoi Todo, who teaches him the Black Flash (黒閃, Kokusen) while fighting Hanami, which can raise the destructive power of their strike to the power of 2.5. During the next case, he and Nobara both kill Death Paintings Eso and Kechizu.

In the Shibuya Incident, Yuji encounters the vengeful Death Painting Choso, who leaves him close to death, allowing Jogo to feed him 11 of Sukuna's fingers. Sukuna takes over and wreaks havoc in Shibuya. Yuji feels responsible for the hundreds of thousands of people Sukuna kills and seeks to stop Kenjaku at all costs. He faces off against Mahito, who kills Nanami and disfigures Nobara in front of him to break his resolve. Yuji's determination is reinforced however, when Todo joins him and they tear Mahito down together, until Kenjaku arrives to absorb the curse. Following the Shibuya Incident, Yuji's execution is reinstated and he goes into hiding with his newly-discovered half-brother Choso.

When Yuta and Naoya arrive to execute him, Yuta heals him with Reverse Cursed Techniques. Yuta, Megumi and the rest join him to stop Kenjaku's plans in the Culling Games. During the Culling Games, he successfully recruits third-year Jujutsu High students Hakari Kinji and Kirara Hoshi, and later Hiromi Higuruma. However, Sukuna exploits his binding vow with Yuji to resurface and transfer his essence into Megumi by making him eat one of Yuji's fingers. Yuji's despair is alleviated when they are able to release Gojo from the Prison Realm. Gojo challenges Sukuna to a duel on Christmas Eve. Determined to end Sukuna and save Megumi, Choso allows Yuji to eat the remaining Cursed Wombs and awaken Blood Manipulation (赤血 操術, Sekketsu Sōjutsu). Kamo and Choso work together in teaching Yuji how to use this technique, while Ui Ui uses his technique to switch Yuji's soul with Kusakabe and Yuta so he could learn their abilities, Simple Domain and Reverse Cursed Technique, respectively.

Yuji faces off against Sukuna alongside the others after Gojo and Kashimo's deaths. He uses Blood Manipulation as well as Sukuna's own Shrine (御厨子, Mizushi) Cursed Technique due to it being engraved on his body as well as his blood relation to Sukuna, his uncle. His lengthy Black Flash flurry against Sukuna greatly impairs the latter's grasp on Megumi's body, forcing the latter to use Binding Vows to rejuvenate his domain and eliminate Yuji. Choso gives hi…

Aoi Todo (東堂 葵, Tōdō Aoi) is a third-year Sorcerer of Kyoto Prefectural Jujutsu High School. He is quite solid in hand-to-hand combat, defeating five Grade 1 Cursed Spirits and 1 Special Grade during an attack in Kyoto. He can apply a flash coating of Cursed Energy to his body for defence. Todo also dislikes anything boring due to his mundane past as a result of his incredible strength. He usually asks his opponent what his type is in women. He believes Yuji Itadori to be his brother and that they went to the same middle school. He also taught Yuji how to control his Cursed Energy. He helps Yuji fight Mahito during the Shibuya Incident, though he loses an arm, which prevents him from ever using his technique, Boogie Woogie (不義 遊戯, Bugi Ugi), again. Eventually, Todo is able to revive his technique using a Binding Vow to change its activation condition from clapping, to hitting a vibraslap attached to his severed arm. This actually greatly augments his switching abilities, as he can swap multiple targets over fifty times per second, equivalent to the vibration within the instrument. During the Shinjuku Showdown, he first helps Takaba and Yuta eliminate Kenjaku, by switching the latter two. Later on, he joins Yuji in battle against Sukuna, raising his spirits after the loss of Choso. Not even Sukuna is capable of adapting to Boogie Woogie, as he is overwhelmed by the amount of switching, which makes Sukuna resort to a Domain Expansion to counter Todo and Yuji. Luckily, Yuta in Gojo's body steps in to block Sukuna's domain with his own. Following the domain clash and a Hollow Purple to hurt Sukuna, Todo supports Yuji in his assault more, before switching in Angel to use Jacob's Ladder again. While Sukuna narrowly manages to reach Angel's level, Todo jumps in front of them to take Sukuna's Black Flash, earning the respect of the King of Curses as he is knocked out.

She detests her twin sister Maki after the latter leaves her and their clan to study to become a Jujutsu Sorcerer. Compared to Maki, who possesses no Cursed Energy at all, Mai possesses a Cursed Technique, albeit possessing a low amount of Cursed Energy. An expert markswoman, she primarily uses a revolver infused with Cursed Energy to take out Curses or other Sorcerers. Her technique, which is kept as a secret for strategic purposes, is Construction (構築術式, Kōchiku Jutsushiki), allows her to materialize objects out of Cursed Energy. The process exhausts her quickly.

The sword also serves as the last connection between the two sisters.

Yuki Tsukumo (九十九 由基, Tsukumo Yuki) is one of the four special grade sorcerers and a former Star Plasma Vessel.

She was a mentor to Aoi Todo, who she scouted one day while traveling. She aims for a world with no Cursed Spirits, a belief that differs from Jujutsu School. Yuki has a habit of asking men she meets what type of girls they like, a habit Todo adopted. After the Shibuya Incident, she shows up to help, volunteering to guard Master Tengen. Towards the end of the Culling Games, when Kenjaku shows up to absorb Tengen, she and Choso go all-out to force Kenjaku to reveal their own Curse Technique and not rely on Geto's, though Tengen warns her not to use her own Domain Expansion against Kenjaku. After an arduous battle though, she succumbs to her injuries, but not without allowing Choso to escape with information on Kenjaku beforehand.
