Maki Zen'in

Maki's naginata is a cursed, long-shafted weapon with a dark red handle and a long, slightly curved metal blade. The blade is sleek and sharp, while the handle features gold details that give it a traditional look. At the bottom of the shaft is a gold metal finial with a small reddish cloth hanging from it. Its size allows it to be used for wide attacks and keeping enemies at a distance.

His family
The most important person in her family life is her twin sister, Mai Zenin.
Although they are physically identical twins, they have an extremely complicated relationship. Maki left the clan to pursue her dream, while Mai stayed and ended up developing resentment towards her. Mai never wanted to become a sorceress and preferred a normal life, while Maki was determined to become someone powerful.

There is also Ogi Zenin, her father, who belongs to the main branch of the clan. His relationship with Maki is deeply conflicted because he believes she does not meet the standards he expects of a Zenin member.
And within the extended family is Naobito Zenin, one of the clan's most important members and its leader for much of the story. He perfectly represents the traditionalism and hierarchy that Maki despises.

The Zenin Clan
The Zenin are one of the Three Great Clans of sorcerer society, along with the Gojo and Kamo. They are an extremely traditional family, obsessed with power, inherited techniques, and their position within the world of jujutsu.
Maki was born into the clan's main family, but her lack of cursed energy caused her to be considered a failure. Instead of receiving the recognition befitting her lineage, she was despised and expected to occupy a subordinate position within the family.
Jujutsu Kaisen
Maki rejected that fate.
Her goal was to become strong enough to prove the Zenin wrong, to become a top-tier sorceress, and eventually return to the clan from a position where they could no longer ignore her.

Personality
Maki is straightforward, determined, proud, and extremely independent. She doesn't like to depend on others and tends to demand a lot from both herself and the people she trains with.
She can seem quite cold or aggressive, especially when she meets someone she considers weak or too passive. With Yuta, for example, she's initially quite harsh because she thinks he needs to stop acting helpless. But behind that harshness is a person who genuinely wants her classmates to grow and become self-reliant.

Maki was born with a Celestial Restriction that reduced her cursed energy to an extremely low level. In return, she received physical abilities superior to those of a normal human: extraordinary strength, speed, stamina, and senses.

But during JJK 0 he had not yet reached his full potential.
The reason was Mai.
Maki and Mai are identical twins, and within the rules of Jujutsu Kaisen sorcery, twins are treated as a single entity from the standpoint of certain restrictions. Mai possessed cursed energy and an innate technique, while Maki practically lacked both. This prevented Maki's Heavenly Restriction from reaching its full potential.
Jujutsu Kaisen
That's why the Maki from JJK 0 is extremely strong physically, but she is not yet the Maki who appears after the incident with the Zenin clan.
When Mai disappears from the equation, Maki finally reaches a state of zero cursed energy, pushing her body to the limit of Celestial Restraint. At that point, her physique and senses reach a level comparable to that of Toji Fushiguro.
Jujutsu Kaisen
Does he have a cursed technique?
No. Maki was born without a usable innate cursed technique.
His fighting style relies primarily on his physical training, martial arts, and cursed tools. That's precisely why his fighting ability is so impressive: he can't simply throw around techniques like most sorcerers.

Outfit in Jujutsu Kaisen 0
She wears the uniform of the Tokyo Magic Technical School: a dark, long-sleeved, high-collared jacket with a traditional cut, paired with a dark, straight-cut skirt. She wears long, thick brown/beige socks and black shoes.
The outfit is quite understated and practical. The glasses stand out a lot against her face and are an essential part of her sorceress look.

Maki is a tall teenager, approximately 170 cm, with a slim and athletic build. She has straight black hair, usually tied back in a short ponytail, with some strands falling over her forehead and framing the sides of her face. Her eyes are small and expressive. In the anime, they are brown, while the manga depicts them as a lighter shade.
Jujutsu Kaisen +1
During Jujutsu Kaisen 0, he uses special glasses that function as a cursed tool, allowing him to perceive curses despite his limited cursed energy. This detail is crucial to understanding his limitations at that time.
