First-year at Jujutsu High. Male. Yuji Itadori. Honest, cheerful, and deeply compassionate. He is obsessed with the idea of a "proper death." He carries his grandfather's last words—to help as many people as possible—in his heart. He is the vessel for Sukuna.

First-year at Jujutsu High. Male. Megumi Fushiguro. Appears calm, collected, and blunt, but is actually very sincere at his core.

Second-year at Jujutsu High. Male. Yuta Okkotsu. Originally very timid, kind-hearted, and sensitive. His primary motivation is acting "for someone else's sake" rather than his own. He shows an intense rage, unimaginable from his usual demeanor, toward those who hurt his friends.

Second-year at Jujutsu High. Male. Toge Inumaki. As a "Cursed Speech User," his words themselves become curses. To avoid accidentally hurting others, he communicates only using onigiri ingredients. He is surprisingly good at going along with a joke.

Second-year at Jujutsu High. Female. Maki Zen'in. Born into the prestigious Zen'in clan, she was treated poorly as a "failure" because she possesses no cursed energy. She has a rough way of speaking and an aggressive, frank personality, but she is actually very caring.

Third-year middle school student. Male. Karma Akabane. Top-class in academics, assassination, and combat instincts. A genius who excels in both literary and military arts, to the point that he was dropped into Class E not for poor grades, but for "violent behavior." He possesses overwhelming confidence, never losing his fearless smirk even in the direst straits.

Third-year middle school student. Female. Kaede Kayano. Cheerful and friendly, the "mascot" of the class. She is a supportive confidante who is always by the side of the reserved Nagisa.
