Megumi Fushiguro is a powerful, grade 1 jujutsu sorcerer and a core student at Tokyo Jujutsu High. Known for his calm, stoic, and deeply pragmatic demeanor, he contrasts sharply with his more impulsive peers. He utilizes the rare Ten Shadows Technique, allowing him to summon powerful shikigami from shadows, including his Divine Dogs and the untamable Mahoraga. Driven by a strict moral code, Megumi fights to protect good people rather than saving everyone blindly. Under the mentorship of Satoru Gojo, his immense potential makes him a key figure in the jujutsu world.

Satoru Gojo is the undisputed "Strongest Jujutsu Sorcerer" and a charismatic teacher at Tokyo Jujutsu High. Instantly recognizable by his striking white hair and the blindfold he wears to manage his sensory overload, Gojo possesses a playful, childish, and arrogant exterior that hides a deeply strategic mind. He wields the rare combination of the Limitless technique, which lets him manipulate space to remain completely untouchable, and the Six Eyes, which grant him near-infinite energy efficiency and perception. Gojo fights to foster a strong new generation capable of revolutionizing the corrupt jujutsu world.

Yuji Itadori is the compassionate, high-energy student. Possessing superhuman physical abilities even before learning jujutsu, Yuji’s life changes forever when he swallows a cursed finger to save his friends, becoming the vessel for the legendary "King of Curses," Ryomen Sukuna. Despite facing immense tragedy, Yuji is defined by his profound empathy and a simple, powerful goal: to ensure people get a "proper death." He fights using Divergent Fist and the devastating Black Flash, relying on raw martial arts prowess and an unbreakable will to protect others.

Nobara Kugisaki is a fierce, confident, and incredibly stylish first-year student at Tokyo Jujutsu High. Rejecting traditional expectations, she is proud of being both a highly capable warrior and a girl who loves fashion and shopping. She fights using her signature Straw Doll Technique, channeling her cursed energy through a hammer, nails, and a straw doll to attack her enemies from a distance or strike their souls directly. With her sharp wit, bold personality, and unwavering loyalty to her friends, Nobara brings a fiery, unapologetic energy to the group.

Kento Nanami is a pragmatic, suit-wearing Grade 1 sorcerer who treats jujutsu like a strict 9-to-5 job. After a stint as a salaryman, he returned to jujutsu to do work that genuinely helps people.
