Yuji Itadori is a young man of average height with a lean, muscular build, light brown eyes, and distinctive spiky pink hair. After becoming Sukuna’s vessel by eating one of his fingers, Yuji gained additional eyes and markings that appear when Sukuna takes control. He initially wears casual clothing but later adopts a customised Tokyo Jujutsu High uniform featuring a red hoodie and red shoes. Yuji is compassionate, fair, and deeply values human life, believing everyone deserves a “proper death.” He avoids killing humans whenever possible, seeing it as morally wrong unless necessary. Despite his serious values, he is energetic, outgoing, humorous, and enjoys spending time with his friends. He is passionate and stubborn when pursuing his goals, though initially naïve about jujutsu and curses. Nevertheless, he learns quickly and adapts well. Normally friendly and composed, Yuji can become intensely angry when confronted with genuine cruelty. Witnessing Mahito’s treatment of Junpei awakened a deep hatred and, for the first time, a genuine desire to kill. One of Yuji’s defining traits is his willingness to sacrifice himself for others. Inspired by his grandfather’s final words about dying surrounded by people, Yuji instinctively risks his own life to protect others... even people he barely knows.

Megumi Fushiguro is a tall, slim young man with fair skin, green eyes, and distinctive spiky black hair. He typically wears the Tokyo Jujutsu High uniform and is known for his serious, stoic appearance. Megumi is reserved, calculating, and easily irritated, often contrasting with the energetic personalities of Yuji, Nobara, and Gojo. From a young age, he was mature and independent, caring deeply about his sister Tsumiki. He dislikes arrogant or cruel people and has a strong, personal sense of justice. Rather than blindly following jujutsu traditions, Megumi acts according to his own conscience, even when it means breaking the rules. Initially, Megumi struggled with the idea of being someone who saves others. He believed saving the wrong person could ultimately harm innocent people. However, he chose to save Yuji because he couldn't accept watching a good person die, eventually embracing the idea that he would "save people unfairly." His motivation to become a sorcerer was also strengthened by his desire to protect Tsumiki. Although distant and secretive, Megumi genuinely values Yuji and Nobara as friends and gradually learns to rely on them. He can be insecure about his abilities and tends to hold himself back, but his potential becomes clearer as he learns to embrace his ambitions and fight for his own future. This growth allows him to unlock his Domain Expansion and become a much stronger sorcerer.

Nobara Kugisaki is a slim, fair-skinned young woman with neck-length light brown hair, orange eyes, and an asymmetrical bob. She wears the Tokyo Jujutsu High uniform with a matching skirt, black tights, brown shoes, and a belt carrying her jujutsu tools. She also enjoys fashion and dressing up. Nobara is confident, outspoken, brash, and fiercely determined to remain true to herself. Although she can initially seem arrogant or abrasive, she is actually caring and loyal, especially toward her friends Yuji and Megumi. She enjoys joking around and teasing others, while also being a fierce trash-talker during fights. Despite her playful side, Nobara stays relatively calm under pressure and is willing to take charge when necessary. Growing up in a small countryside village, Nobara always felt different from those around her and disliked the narrow-minded environment. She admired outsiders such as Saori and dreamed of moving to Tokyo, eventually making a promise to reunite with her childhood friends there. As a sorcerer, Nobara refuses to let society or tradition dictate who she should be. She strongly admires Maki for fighting against her family's oppression and shares a similar belief in judging people by their character rather than their circumstances. Nobara refuses to excuse cruelty simply because someone had a difficult life and strongly believes that people should remain true to themselves while treating others with humanity.
