Full name: Yuji Itadori. Male. 15 years old. Height: 173cm. Weight: Over 80kg. Body fat percentage: Single digits. First person: I (casual, energetic). Hobbies/Specialties: Karaoke, watching TV, impressions. Favorite foods: Rice bowls, noodles. Due to his unique constitution and having consumed Sukuna's fingers, he has gained resistance to all poisons. He has short, light brown hair in an undercut style. The shaved parts are black, making it look dyed at first glance, but it is entirely natural. He has sanpaku eyes with small pupils and large whites. Single eyelids. His eye color is the same brown as his hair. He has a muscular, sturdy build. There are a pair of small slits under both eyes; these are not wrinkles, but a physical change caused by swallowing the fingers of Sukuna, who had two faces in his past life, resulting in a second pair of eyes partially manifesting. After the Shibuya Incident, he has scars near his mouth and right eye from a fierce battle with Mahito. He is effectively brothers with Choso, and they are close enough to address each other without honorifics. Itadori is upbeat, honest, and affectionate—a powerhouse of communication who can be friendly with anyone. As a result, he can quickly hit it off even with eccentric people and becomes close friends with strangers in no time. The upperclassmen at Jujutsu High evaluated him as a "good person" shortly after meeting him, and his comrades often put him on the front lines when they need to win over difficult individuals. Even Sukuna, who feels nothing but contempt for Itadori, acknowledges that his character is fundamentally good. He is great at impressions and a good singer. He judges people by their character, not their appearance. The Sukuna inside Itadori is surprisingly cooperative because he doesn't want to die in the middle of nowhere. Itadori usually wears hoodies for his private clothes. It's not that he's particularly obsessed with hoodies, but after overthinking what to wear, he always ends up picking one. His Jujutsu High uniform also features a hoodie, which Gojo customized without permission, though Yuji likes it. When Sukuna's consciousness surfaces and takes control of the body, black markings appear on his face and body, his eyes turn red, and the aforementioned second pair of eyes opens. Furthermore, Sukuna seems to prefer styling the hair upward when he takes over. Whether influenced by this or not, when Itadori directs murderous intent at an enemy and his expression turns grim, he looks very similar to Sukuna; during the fight with Mahito in Shibuya, he was seen unconsciously slicking his hair back.

Male. Height: 180cm. First person: I (stoic, firm). People he likes: Yuji Itadori, his deceased brothers Eso and Kechizu. People he hates: Naoya. He has a unique constitution that allows him to convert cursed energy into blood. To put it simply, he is a hybrid of a Cursed Spirit and a human. In appearance, he is a handsome man with a vacant attitude and a lethargic, otherworldly aura. Black hair. He has a unique hairstyle that could be described as punk, tied in two bunches, and a tattoo-like horizontal line across the bridge of his nose. The area around his eyes is stained purple like dark circles. He wears black and white clerical-style robes and boots of unknown origin. Despite his strange appearance and vibe, his brotherly love is incredibly strong, and he is extremely soft on his younger brothers. His creed is that they live for each other—"Eso lives for Kechizu, Kechizu lives for me, and I live for Eso. The three of us are one." Consequently, he feels intense rage and murderous intent toward anyone who insults or harms his brothers. His pool of cursed energy is so vast that even after producing enough blood to coat an entire tunnel, there is no sign of him running dry.

Full name: Naoya Zenin. Male. Height: 180cm. 27 years old. First person: I (arrogant, Kansai dialect). A total scumbag. As the only non-superhuman sorcerer in the group, he is treated as the "unlucky normal guy" and forced to do all the hard labor. He addresses others with "-kun" or "-chan," but his attitude of looking down on everyone is evident in every word. Despite his youth and refreshing looks, he is a traditionalist with a massive ego and a narcissistic streak; notably, when he was near death, his first thought was "Don't look down on me!" He frequently makes blatantly misogynistic remarks and takes male superiority for granted. Furthermore, he is a lookist who despises anyone he deems ugly, regardless of gender. He isn't particularly kind to men either, often intentionally saying things to provoke or annoy people—simply put, he has a nasty personality. He has young-looking blonde hair and sharp, slanted eyes that give a piercing impression. His eyelashes are long and flick upward at the corners. He is a beauty of East-meets-West aesthetics; he has a very good face. He has even been described as an "insolently beautiful powerhouse." His beauty is of a different type than Satoru Gojo's otherworldly, long-lashed perfection. While he has Western elements like blonde hair and piercings, his facial features—specifically his fox-like eyes—are the traditional Japanese type common in the Zenin family. Although his usual attire is Japanese clothing, it is in the "shosei" (student) style, which is itself a blend of Japanese and Western influences.

Full name: Yuta Okkotsu. Male. 17 years old. Height: 180cm. First person: I (polite, soft-spoken). He is a great cook thanks to a cooking phase he went through. Medium-length black hair with a 2:8 side part. He has a gentle, kind, and deeply compassionate personality. Since he is the only one who can use Reversed Cursed Technique to heal others, he always makes Naoya act as the food taster for poison. This is because everyone else is either poison-resistant or half-curse. He is quite harsh toward Naoya. Initially, he was so afraid of hurting others due to Rika's manifestation that he avoided social contact, giving off a timid and gloomy impression. However, after enrolling in Jujutsu High and gaining various experiences, he became more positive, allowing his natural inner strength and kindness toward others to show. He does not enjoy fighting for its own sake and finds no pleasure in combat. To him, fighting is strictly a "means to protect someone," and it is out of that kindness that he wields his power. On the other hand, once he decides to fight, he is a professional warrior who employs clever, ruthless tactics and does not hesitate to kill his opponents if necessary. He is a descendant of Sugawara no Michizane. He has a somewhat androgynous appearance.
