Yuji Itadori is a 15-year-old first-year student at Tokyo Jujutsu High and the vessel of Ryomen Sukuna, the King of Curses. Standing about 5'8" (173 cm), he has an athletic build, short pink hair, and warm brown eyes. Before becoming a sorcerer, Yuji possessed extraordinary physical strength, speed, reflexes, and endurance far beyond that of a normal human. After swallowing one of Sukuna's fingers to save his friends, he entered the world of jujutsu and chose to dedicate his life to protecting others. Yuji is cheerful, friendly, compassionate, and optimistic, but he also carries immense emotional burdens from the lives he has been unable to save. His personal goal is to ensure people receive a proper death, believing no one should die alone or with regret. In combat, he specializes in close-range martial arts enhanced by cursed energy, using techniques such as Divergent Fist and Black Flash with remarkable consistency. Although Sukuna resides within him, Yuji refuses to let evil define who he is, constantly proving his own resolve through his actions. He values teamwork, forms strong friendships, and never hesitates to risk himself for innocent people. His determination, empathy, adaptability, and relentless willpower allow him to keep growing stronger despite overwhelming odds and heartbreaking losses.

Nobara Kugisaki is a 16-year-old first-year student at Tokyo Jujutsu High who came from a small countryside village to pursue life as a jujutsu sorcerer in Tokyo. Standing about 5'3" (160 cm), she has shoulder-length auburn hair, brown eyes, and a stylish appearance that reflects her confident personality. Bold, outspoken, fearless, and fiercely independent, Nobara refuses to let anyone dictate how she should act as a woman, proudly embracing both her strength and femininity. She is blunt and confident, often teasing others, yet she is deeply loyal to her friends and willing to risk her life to protect them. Nobara fights using the Straw Doll Technique alongside a hammer, nails, and straw doll, allowing her to attack opponents directly or damage them through Resonance by targeting connected body parts or cursed objects. She is highly intelligent in battle, quickly analyzing situations and finding creative ways to gain the upper hand. Despite her tough exterior, she treasures the relationships she forms and refuses to abandon those she cares about. Her courage, determination, sharp wit, and refusal to back down make her an invaluable teammate and a formidable jujutsu sorcerer capable of facing overwhelming enemies with unwavering confidence.

Megumi Fushiguro is a 15-year-old first-year student at Tokyo Jujutsu High and one of the most gifted young sorcerers of his generation. Standing around 5'9" (175 cm), he has a lean build, messy black hair, and dark blue eyes that reflect his calm and observant nature. He inherited the legendary Ten Shadows Technique from the Zenin Clan, allowing him to summon powerful shikigami for offense, defense, tracking, and support. Quiet, intelligent, and reserved, Megumi rarely expresses his emotions openly, preferring to let his actions speak instead. He has a strong sense of justice but believes not everyone deserves to be saved equally, choosing to protect those he believes are genuinely good. Despite his serious personality, he deeply cares about his friends and will risk everything for them without expecting recognition. In battle, he relies on strategy, adaptability, and careful planning rather than overwhelming force, making him a dangerous opponent even against stronger enemies. His Domain Expansion, Chimera Shadow Garden, greatly enhances his abilities by allowing him to manipulate shadows more freely. Gojo recognizes Megumi's enormous potential, believing he can one day surpass even special grade sorcerers. Though burdened by his past, he continues moving forward with unwavering determination.

His signature abilities include Infinity, Cursed Technique Lapse: Blue, Reversal: Red, Hollow Purple, Reverse Cursed Technique, and his Domain Expansion, Unlimited Void. Gojo is incredibly intelligent, quick-witted, and confident, often appearing playful, sarcastic, and carefree. Beneath that attitude, however, he is deeply compassionate toward his students and determined to change the corrupt jujutsu society by raising a new generation of powerful sorcerers. Despite his overwhelming strength, he carries the burden of being isolated by his power and losing people close to him. In battle, he remains calm, analytical, and nearly impossible to overwhelm, combining unmatched speed, hand-to-hand combat skills, and cursed energy control. His charisma, humor, unwavering confidence, and overwhelming power have made him one of the most iconic and respected sorcerers in the world of Jujutsu Kaisen.
