Yuta Okkotsu is a formidable Special Grade jujutsu sorcerer and the protagonist of Jujutsu Kaisen 0. Initially a traumatized teenager, he is bound by a curse—his late childhood friend, Rika. Guided by Satoru Gojo, he learns to wield immense cursed energy and becomes a powerhouse. Background and Origins Born on March 7, 2001, Yuta is a distant descendant of the legendary sorcerer Michizane Sugawara and related to Satoru Gojo. His journey into the jujutsu world is sparked by tragedy. After his childhood friend Rika Orimoto is killed in a car accident, Yuta’s grief and love unconsciously cursed her, turning her into an overwhelmingly powerful, Vengeful Cursed Spirit that fiercely protects him. Because of Rika's violent tendencies toward anyone who threatens Yuta, he is placed under a secret execution order. Satoru Gojo intervenes, taking Yuta under his wing and enrolling him at Tokyo Jujutsu High to teach him how to control his staggering power. Personality and Character Arc Initially, Yuta is timid, deeply depressed, and socially isolated, believing that he is too dangerous to be around others. Through his training and his friendships with peers like Maki Zenin, Toge Inumaki, and Panda, he slowly finds the confidence to live and fight for others. Unlike many classic shonen protagonists, Yuta is naturally soft-spoken, kind-hearted, and cautious. However, he hides a simmering, dangerous intensity and is fiercely protective of his friends, willing to go to dark extremes if necessary. Abilities and Fighting Style Yuta is officially recognized as one of only four Special Grade sorcerers. His immense strength stems from a combination of several factors: Boundless Cursed Energy: Yuta possesses cursed energy levels that even surpass Gojo. The "Copy" Technique: Through Rika, Yuta has the incredibly rare ability to replicate any cursed technique he witnesses. Cursed Spirit Rika: Even after freeing Rika's soul at the end of the prequel, Yuta retains a connection to a manifestation of Rika, which acts as a massive reserve of power, weaponry, and additional cursed energy. Versatility: He uses this combination of raw energy and diverse techniques alongside the Reverse Cursed Technique, which allows him to heal himself and others rapidly in prolonged combat.

Toge Inumaki is a skilled jujutsu sorcerer who fights evil cursed Spirits. He uses Cursed Speech, a rare magic where his spoken words force targets to obey. To avoid hurting others by accident, he only speaks in names of rice ball ingredients like "salmon" and "bonito flakes" His Power and the Price: Every command he shouts (like "get crushed" or "sleep") is forced onto his target. However, giving big commands takes a toll on his body, often leaving his throat sore or bloody. The Look: He zips his high-collar uniform all the way up to his nose to muffle his words and keep them from activating accidentally. He had purple eyes and fang seal markings on his face, he had medium length white hair. Personality: Despite his intimidating power, he is deeply caring, quiet, and fiercely loyal to his friends.

Maki Zenin is a fiercely independent and resilient jujutsu sorcerer from the renowned Zenin Family. Born with minimal cursed energy due to a Heavenly Restriction, she was severely mistreated and rejected by her clan. Determined to prove her worth, she defected to Tokyo Jujutsu High to become a formidable, weapon-wielding powerhouse. Appearance & Personality Maki is a tall, athletic young woman with dark hair (seaweed-green in the anime) and piercing eyes. Following a brutal encounter with a cursed spirit, she was left with permanent burn scars across her face and upper body. Personality-wise, she is blunt, headstrong, and determined. She fiercely rejects the sexist, traditionalist views of her family and is driven by an ambition to dismantle oppressive systems from within the jujutsu world. Abilities & Powers Because she lacks cursed energy, Maki relies on peak physical conditioning and is an absolute master of cursed tools—such as the special-grade tool Playful Cloud. Following the tragic sacrifice of her twin sister, Mai, Maki's cursed energy was entirely stripped away. This finalized her Heavenly Restriction, granting her a "body of steel" on par with Toji Fushiguro, making her one of the most physically formidable characters in the series.
