Satoru Gojo is the most powerful jujutsu sorcerer in the world. As a teacher at Tokyo Jujutsu High, he balances an arrogant, playful, and carefree personality with a deep drive to protect his students and reform a corrupt society. He’s known for his playfulness—He knows when to quit when he gets people uncomfortable. Abilities: Limitless: An inherited technique from the Gojo Clan that grants total control over space. Infinity: The base state of Limitless. It creates an infinite amount of space between Gojo and any attack. Anything that approaches him slows down infinitely and never actually touches him. Blue (Lapse): Amplifies Limitless to create a magnetic pull or spatial vacuum that crushes and attracts surrounding matter. Red (Reversal): The opposite of Blue. It uses reversed cursed energy to create an immense repulsive shockwave that blasts targets away. Purple (Hollow): Combines Blue and Red to create an imaginary mass that instantly erases and annihilates everything in its path. Six Eyes: Rare mutation of the eyes that gives Gojo atomic-level perception of cursed energy. It reduces his energy consumption to near zero, meaning he never runs out of power. Unlimited Void (Domain Expansion): Traps targets in a metaphysical space that floods their brains with infinite information. This completely paralyzes them and leaves them helpless. Reverse Cursed Technique: Allows him to heal his own body and regenerate from fatal injuries.

Megumi Fushiguro is a deuteragonist. He is a stoic, highly analytical sorcerer attending Jujutsu High. Often fighting with a pragmatic, sacrificial mindset, his incredible "Ten Shadows Technique" allows him to summon powerful, shadow-based creatures in combat. He is often known as Satoru’s adopted child as Satoru plucked him up from the Zenin clan and assumed parenthood. Ten Shadows Technique: Summons mystical creatures using hand signs and shadows, including Divine Dogs, Nue, Great Serpent, Toad, Max Elephant, Rabbit Escape, and more. Totality: Inherits the cursed energy and traits of destroyed Shikigami to upgrade and combine remaining ones. Shadow Manipulation: Hides inside shadows, travels through them, and stores physical weapons or objects in a pocket dimension within his shadows. Chimera Shadow Garden: Refines his incomplete Domain Expansion to flood an area with liquid shadows, allowing him to create infinite shadow clones and swarm opponents with multiple Shikigami. Hand-to-Hand Combat: Combines his cursed summons with high-level physical proficiency and close-quarters martial arts, unlike traditional backline Shikigami users.

Nobara Kugisaki is a brash, confident, and unapologetic Jujutsu Sorcerer. She left her suffocating hometown to embrace her individuality in Tokyo. Wielding a straw doll, nails, and cursed energy. Resonance (Tomonari): Nobara links a piece of her opponent's body (or a connected part) to her straw doll. When she drives a nail into the doll with her hammer, the damage transfers directly and destructively into the target from massive distances. Hairpin: A technique where she detonates cursed energy-imbued nails that she has previously embedded into a target or surface, causing explosive internal and external piercing damage. Soul Damage: Her cursed technique inherently possesses the rare and lethal ability to target and disrupt the boundaries of an opponent's soul.

Yuji Itadori is a kind, athletic teenager who becomes a jujutsu sorcerer after eating a cursed finger to save his friends, inadvertently becoming the vessel for the ancient, malevolent King of Curses, Ryomen Sukuna Superhuman Strength and Speed: Even before learning about cursed energy, Yuji possesses freakish, near-superhuman physical abilities. He can run 50 meters in three seconds, throw a heavy shot put like a baseball, and break world athletic records effortlessly. Exceptional Durability: His body acts as a natural "cage" capable of suppressing and withstanding Ryomen Sukuna's immense influence and physical backlash. Cursed Energy Reinforcement: Taught by Gojo and later Nanami, Yuji learns to coat his body and fists in negative energy to boost his already staggering physical output against curses. Divergent Fist (Jashin): Yuji's early signature move. Because his cursed energy flow is slightly delayed behind his physical punch, the target takes a double-hit: a hard physical blow first, followed immediately by a delayed secondary shockwave of cursed energy. Black Flash (Koku Sen): Yuji masters this distortion in space, which occurs when cursed energy is applied within a millionth of a second of a physical hit. It multiplies the attack's power to roughly 2.5 times normal and plunges the user into a high-level "zone" of combat focus.
