Kasumi Miwa is a kind-hearted, down-to-earth Grade 3 sorcerer characterized by her striking sky-blue hair cut into straight bangs, an asymmetric side fringe, and dark blue eyes, usually paired with a standard dark jujutsu uniform trousers suit. Lacking an innate cursed technique, she fights using the New Shadow Style swordsmanship, focusing heavily on Simple Domain and its automated defense variant Batto Sword Drawing (Quick Draw) to intercept attacks within her immediate radius. Despite her crippling low self-confidence and tendency to view herself as incompetent among prodigies, her bubbly persona often masks a deep loyalty,

Aoi Todo is a powerful Grade 1 sorcerer and third-year student at Kyoto Jujutsu High School in Jujutsu Kaisen. Known for his eccentric personality, immense physical strength, and high battle intelligence, he famously judges other men by asking about their preference in women, which leads him to claim Yuji Itadori as his "brother". In combat, Todo relies on his incredible hand-to-hand martial arts skills and his innate cursed technique, Boogie Woogie, which allows him to instantly swap the positions of any two targets containing cursed energy simply by clapping his hands

Noritoshi Kamo is a third-year student at Kyoto Jujutsu High School and a powerful Grade 1 jujutsu sorcerer. As the illegitimate son of the prestigious Kamo clan, he faces immense pressure to become the perfect heir, leading him to maintain a strict, stoic, and traditional demeanor. In battle, he utilizes the clan's prized inherited technique, Blood Manipulation, which allows him to control his own blood to reinforce his body, guide fired arrows, or slash through enemies. Beneath his rigid exterior, his primary motivation is to elevate his mother's social status within the clan, making him a deeply loyal and protective teammate.

Momo Nishimiya is a third-year student at Kyoto Jujutsu High School and a Semi-Grade 2 jujutsu sorcerer. Visually distinct for her petite, witch-like appearance, she fights while flying on a broomstick using her innate technique, Tool Manipulation, which gives her excellent aerial scouting, wind-based offensive capabilities, and telekinetic control. Momo is highly supportive of her female classmates, often speaking out about the immense societal pressure and strict beauty standards forced upon women within the jujutsu sorcerer world.

Ultimate Mechamaru is the sorcerer alias of Kokichi Muta, a second-year student at Kyoto Jujutsu High School who operates a mechanical puppet from afar. Due to a Heavenly Restriction, Kokichi was born with a severely fragile, painful body lacking a right forearm and skin sensitive to all light, in exchange for vast quantities of cursed energy. He uses his Puppet Manipulation technique to control Mechamaru, a heavily armed robot capable of flying, firing energy blasts, and fighting in close combat. Kokichi's tragic primary motivation is to undergo medical treatment that would heal his human body, allowing him to finally meet his classmates in person.

Mai Zen'in is a second-year student at Kyoto Jujutsu High School and a Grade 3 jujutsu sorcerer. Born into the prestigious Zen'in clan, she suffered intense abuse alongside her twin sister, Maki, for lacking high levels of cursed energy and being unable to see curses without special glasses. Unlike her sister, Mai never wanted to be a sorcerer but was forced into the lifestyle out of spite, causing her to adopt a cynical, blunt, and seemingly cruel personality to cope with her trauma. In combat, she uses a standard revolver to channel her rare innate technique, Construction, which allows her to create a single physical object—such as a single bullet—from scratch using her cursed energy, though the process takes a severe toll on her body.

Arata Nitta acts as a crucial medical support in Jujutsu Kaisen, though his innate technique, Painkiller, does not actually heal injuries. Instead, his ability instantly "freezes" existing wounds to stop bleeding, halt further deterioration, and dull pain, effectively stabilizing dying characters like Nobara Kugisaki and Yuta Okkotsu. For true cellular regeneration and healing, he relies on a tag-team dynamic with Shoko Ieiri, the school's primary doctor, who uses Reverse Cursed Technique to physically mend the stabilized damage.

Yuji Itadori is the main protagonist of Jujutsu Kaisen, a first-year student at Tokyo Jujutsu High School who possesses unmatched physical strength, agility, and durability even without cursed energy. His life changes forever when he swallows a cursed finger to save his friends, accidentally becoming the human vessel for Ryomen Sukuna, the legendary and malevolent King of Curses. Sentenced to a delayed execution, Yuji dedicates his life to consuming all of Sukuna's fingers so the monster can be destroyed with him, driven by a deeply ingrained desire to give people a "proper death." Despite his terrifying burden, Yuji maintains a cheerful, empathetic, and friendly personality, while rapidly evolving into a lethal combatant who utilizes his specialized martial arts, the Divergent Fist technique, and the devastating Black Flash phenomenon to exorcise dangerous curses.
