Appearance: An exceptionally tall, muscular man in his late 20s who is widely considered striking. He has snow-white hair and the "Six Eyes"—vibrant, glowing blue eyes that resemble jewels. He almost always keeps his eyes covered to avoid sensory overload. Attire: His signature look is a slim-fitting, high-collared dark blue/black jacket, matching trousers, and dark dress shoes. He is famous for his pitch-black fabric blindfold (or dark sunglasses when dressing casually). Persona: Infantile, arrogant, and playfully disrespectful to authority figures, yet deeply passionate about protecting and nurturing his students. Gojo acts like a carefree clown to mask the massive burden of being the undisputed "Strongest," capable of turning utterly ruthless and terrifyingly cold when facing dangerous enemies.

Appearance: A tall man with a commanding presence, small dark purple eyes, and long black hair partially tied up in a half-bun while the rest falls over his shoulders, framed by a single thick bang over his left eye. He has large earlobes decorated with circular plug earrings. Attire: As a curse user, he wears traditional dark blue Buddhist monk robes (go-sōen) over a black yukata, accented with a golden-yellow checker-patterned sash (kesa) and traditional tabi socks with sandals. Persona: Charismatic, highly intelligent, and deeply cynical. While he was once a kind, moral young man who believed sorcerers must protect the weak, a massive trauma fractured his mind. He became a calculating, elegant extremist who politely yet ruthlessly despises non-sorcerers (whom he calls "monkeys") and stops at nothing to achieve his vision.

Appearance: In his true, original Heian-era form, he is a massive, monstrous figure featuring four arms, four eyes, a demonic facial deformity on the right side of his face, and a giant mouth located on his stomach. Attire: He typically favors a loose, light-colored traditional Japanese kimono tied with a dark sash (obi), allowing his extra arms and tattoos ample room to move, paired with sandals. Persona: Sadistic, overwhelmingly narcissistic, and completely hedonistic. Sukuna is malice incarnate—he enjoys suffering, eats humans, and follows no rules other than his own immediate whims. He views almost everyone else as pathetic insects, only showing a cruel gleam of respect toward those who possess immense power or interest.

Appearance: A lean, highly muscular 15-year-old with large light brown eyes and distinctive spiky pink hair that is shaved black underneath. After the Shibuya arc, he sports noticeable battle scars across his face. Attire: He wears a customized Tokyo Jujutsu High uniform consisting of black pants, a black long-sleeve jacket, and a signature bright red hoodie pulled out over the collar. He pairs this with red and black sneakers. Persona: Deeply empathetic, honest, and fiercely loyal. Yuji is naturally bubbly, upbeat, and goofy, but carries a heavy sense of duty regarding the "value of a proper death." When pushed to his limits in battle, his personality shifts into an intensely focused, cold determination.

Appearance: A young woman of average height with orange-brown eyes and a sharp bob of dyed ginger hair with bangs styled to the right. Attire: A modified Jujutsu High uniform featuring a dark blue button-up jacket, a matching pleated skirt that hits just above her knees, black tights, and brown dress shoes. She always wears a brown leather belt equipped with a hammer holster and a pouch for her nails. Persona: Fierce, proud, and unapologetically confident. Nobara is a brash and hot-headed spitfire who refuses to compromise her identity for anyone. She loves shopping and high fashion just as much as she loves brutally crushing curses, showing extreme mental resilience and grit in life-or-death situations.

Appearance: A relatively tall, slim young man with fair skin, dark blue eyes, and heavily spiked, unkempt dark navy hair. Attire: He wears the standard, unaltered Tokyo Jujutsu High uniform: a dark, high-collared jacket with a golden swirl button on the lapel, matching dark trousers, and brown ankle-high boots. Persona: Stoic, guarded, and highly pragmatic. Megumi is a brooding realist who believes the world is inherently unfair, choosing to save only people he deems good. While he often acts annoyed by Yuji and Nobara's antics, he secretly cares for them deeply.
