Megumi Fushiguro is a tall, slender young man with fair skin and strikingly sharp, spiky dark-blue hair that juts out in all directions, paired with calm, deep-green eyes. Mentally, he is a deeply pragmatic, guarded, and stoic individual who operates on a strict personal moral code rather than standard societal rules. He is inherently secretive and tends to suppress his emotions, often appearing distant or uncaring, but underneath his cold exterior lies a fierce protectiveness for those he deems "good people," like his sister Tsumiki and his close friends. While he possesses an immense, genius-level talent for jujutsu sorcery, he historically suffered from a lack of personal ambition and a self-sacrificing mindset, frequently defaulting to lethal, last-resort tactics until pushed to value his own life and unleash his true, unhinged potential.

Yuji Itadori is a lean, muscular teenager standing at 5'8" (173 cm) with distinct spiky pink hair that is styled in an undercut with dark brown or black roots, and large, expressive light brown eyes. Beneath his eyes, he bears a pair of small, closed slits, which are the physical mark of formerly serving as the vessel for the cursed spirit, Sukuna. Mentally, Yuji is deeply empathetic, fiercely loyal, and fundamentally altruistic, driven by his grandfather’s dying wish to ensure he helps others so he can "die surrounded by people." He possesses a cheerful, easygoing demeanor and an indomitable will, allowing him to maintain his profound value for human life and a resilient sense of justice even when facing severe psychological trauma and brutal battles.

Nobara Kugisaki is a fairly short, young woman standing at 5'3" (160 cm) with an athletic build, styled in a chin-length, asymmetrical bob-cut of dyed orange hair and matching orange eyes. She wears a customized version of the Tokyo Jujutsu High uniform, which consists of a dark blue button-down jacket, a matching pleated skirt, brown tights, and a signature leather belt that holds her hammer, nails, and straw doll. Mentally, Nobara is unapologetically bold, fiercely independent, and brimming with self-confidence, driven by a desire to escape her rural upbringing and experience urban life in Tokyo. She possesses a brash, hotheaded demeanor and highly direct communication style, taking immense pride in being both a highly capable, ruthless fighter and a fashionable young girl. Despite her sometimes arrogant or prickly exterior, she maintains a strong moral code, a pragmatic worldview, and deep, protective loyalty to her fellow classmates, Yuji and Megumi

Satoru Gojo is an exceptionally tall, strikingly handsome man standing at 6'3" (190 cm) with spiky snow-white hair and the breathtaking, vibrant sky-blue "Six Eyes", which he usually conceals beneath a signature black blindfold or dark sunglasses. He possesses a lean yet highly athletic and muscular physique, typically wearing the dark, high-collared Tokyo Jujutsu High staff uniform. Mentally, Gojo is complex, fiercely confident, and flips between a playful, carefree childishness and a terrifyingly cold ruthlessness when facing enemies. Fully aware of his status as the strongest sorcerer alive, his immense power breeds an arrogant, nonchalant demeanor that often frustrates his superiors, yet he is deeply driven by a noble desire to foster a strong, reliable new generation of sorcerers to revolutionize the jujutsu world rather than simply seizing power himself.
