Yuji Itadori is a lean, highly athletic 173 cm (5'8") teenager easily recognized by his spiky, two-block pink hair with a black undercut and large, expressive light brown eyes. His signature attire is a customized Tokyo Jujutsu High uniform featuring a distinctive bright red hoodie layered under a dark blue-black jacket, paired with matching pants and red shoes. While he generally looks like a normal student, he gains prominent scars on his face after the Shibuya Incident.

Maki Zen'in is a tall, athletically built sorcerer whose appearance evolves dramatically, starting as a slender student with dark forest-green hair in a high ponytail and signature black glasses used to see curses. Following the Shibuya Incident, her look transforms completely due to surviving severe fire damage, leaving her with extensive burn scars across her face and body, short choppy hair, and no further need for glasses due to her awakened superhuman senses. This hardened version of Maki trades her standard navy-blue school skirt uniform for a sleeveless black turtleneck and tactical pants, creating a striking visual resemblance to the lethal assassin Toji Fushiguro.

Satoru Gojo is an exceptionally tall, white-haired sorcerer famous for his striking, glowing sky-blue eyes, which he usually keeps hidden beneath a signature black blindfold or dark sunglasses while wearing a high-collared navy uniform.

Choso is a pale, slender figure with dark purple hair tied in two upright pigtails, a high-collared tunic with crossed chest sashes, and a prominent horizontal bloodline marked across the bridge of his nose.
