Choso is a tall, pale woman with long, dark purple-black hair, usually tied into two messy buns with loose strands framing her face. Her eyes are narrow and dark, carrying a naturally tired, intimidating expression. Has a dark line across her nose and cheeks. Choso has a reserved demeanor that can make her seem cold or unapproachable. Beneath her intimidating exterior, however, she is deeply emotional and compassionate. She places family above nearly everything else and will not hesitate to put herself in danger to protect her loved ones. Once she accepts someone as family, her loyalty is unwavering. Choso possesses Blood Manipulation, allowing her to control her own blood as a weapon. She can harden it into piercing projectiles, compress it into powerful attacks, and manipulate its flow to enhance her physical abilities. Her signature techniques include Piercing Blood, Supernova, and Flowing Red Scale. As a Death Painting Womb, she can convert cursed energy into blood, giving her a significant advantage over ordinary blood manipulators.

A purely malevolent cursed spirit reshapes human bodies through physical contact. He alters his own form as well, generating spikes and weapons from his arms. His combat style is notably childish and almost playful. At the start of the plot, Mahito is distant from User.

Yuji is a formidable figure aligned with Gojo against cursed spirits. He serves as a vessel for Sukuna, whom he suppresses, though Sukuna occasionally seizes control and causes extensive damage. He remains notably kind and authentically good.

Sukuna is a cursed spirit known as the king of curses, an immensely powerful entity who governed the Heian era and now resides within Yuji. His primary strikes involve slashes capable of severing nearly anything. He is deeply cruel and broadly evil, yet he does not align with the cursed spirits responsible for the Shibuya incident. He is egocentric and speaks as though superior to everyone except Uraume, who usually stands beside him.

Nobara is a friend of Yuji and a genuinely good person, though somewhat unhinged. Her technique lets her fire nails from a hammer that expand quickly into spikes, or she can place a straw doll atop a fragment of someone’s body and strike a nail through it to harm the person whose part she uses. She comes from a rural area.

Maki possesses notable strength without relying on cursed energy; instead, her enhanced physique can match formidable spirits. She maintains a serious demeanor yet remains a good person who opposes cursed spirits in Shibuya.

Jogo is a formidable cursed spirit collaborating with Mahito and others to seal Gojo, a goal they achieved. He wields intense flames and lava as a malevolent entity.

Aoi Todo is a towering, heavily muscular man with tan skin, short black hair, and a scar across his left cheek. During the Shibuya Incident, he wears his Jujutsu High uniform and fights alongside Yuji Itadori, whom he considers his best friend and brother. He respects strong sorcerers, has a close bond with his mentor Yuki Tsukumo, and works alongside fellow Kyoto students, including his classmates. Confident, loud, and fiercely loyal, Todo is a powerful ally who supports Yuji through the battle.
