— Yuki Tsukumo.

Star Rage (Innate Technique): Yuki's technique allows her to manipulate her own virtual mass. She can pile infinite mass onto her physical strikes, making her punches devastatingly strong and ignoring the usual limits of physics. Garuda: She fights alongside a unique Shikigami named Garuda. Rather than a typical spiritual beast, Garuda is manipulated through Yuki's Star Rage technique, acting as a powerful, mass-imbued projectile or a whip during combat. Soul Research: Because of her unique status as a surviving Star Plasma Vessel, she gained profound, advanced knowledge of how human souls function. She compiled extensive notes on souls that later proved vital in the battle against Kenjaku.

While her wits are not always on display due to her straightforward attitude, Yuki is as smart as she is strong and goes into every situation with a considerable amount of thought. Using her advanced knowledge of jujutsu, Yuki vigorously analyzes her opponent's every move throughout a battle, taking mental notes of every technique used and every countermeasure that is taken.

As a former Star Plasma Vessel, Yuki has a particularly complicated relationship with Tengen. She agreed to protect them alongside Choso during the Culling Game because she wanted to speak with Tengen. Yuki disagrees with Tengen's methods of retaining their immortality and resents them for constantly sacrificing young women. She even claimed she would've sided with the Time Vessel Association if their goal was to seize Riko Amanai instead of killing her. Yuki can hear her fellow vessels within Tengen and refuses to tell Tengen about them because she feels they're undeserving and it's her duty not to make things so simple for them.

Yuki's ideology led to a deep conversation with Suguru Geto about how to exterminate curses. She inadvertently led to Geto consider killing every non-sorcerer to rid the world of cursed spirits. Yuki admitted this was a viable option but also clarified she would never do that. She saw Geto clearly struggling with his morality as a sorcerer and advised him to decide how he feels about the other side in order to move on. Yuki even tried to ease his mind regarding Riko Amanai's death.

Yuki strongly believes that treating symptoms of cursed energy (exorcising spirits one by one) is a flawed system. She views people born with Heavenly Restrictions—like Toji Fushiguro—as steps toward human enlightenment. Because her goals align with solving the root cause of curses, she spent her time researching human souls and was widely considered an intellectual trailblazer in jujutsu society.

Yuki is a very tall young woman with a slender yet athletic build and light skin. She has long blonde hair that extends well down her back with two tufts on in front of each side of her face. She has wide brown (pink in the manga) eyes with thin eyebrows and pronounced eyelashes.

She has sported a few different outfits, but currently appears in the anime with a sleeveless, heather indigo top reminiscent of female Chinese martial artists' attire with a gold mandarin collar. The vest is tucked into high-waisted stone blue jeans. Most of her stomach area is covered with a buttoned grey bodice. She finishes this outfit with a pair of brown heeled boots.

During the Culling Game, Yuki wears a black sleeveless turtleneck top with a zipper on the neck and the Jujutsu High crest on the zipper’s button. This attire continues with red baggy cargo pants, which also carries a button with the same crest, with large black vertical lines on the pockets that has black ribbons attached to the pockets. Finally, this attire is completed with dark-colored boots.

Yuki travels around on a motorbike and wears appropriate attire while she isn't working. She has a leather biker jacket, with a dome helmet and goggles. In 2007 when Yuki first met Suguru Geto she wore a heather indigo sleeveless turtleneck top, dark blue jeans with a black belt and black combat boots for a more casual look than her current, more battle-oriented one. She wore this same outfit a few years later when she introduced herself to a young Aoi Todo, except she wore a black fishnet top with a black leather jacket and black gloves.

Yuki tsukumo is a character in the Jujutsu Kaisen series. She is one of only four special grade jujutsu sorcerers.[1] Yuki is not aligned with Jujutsu High, so her reputation paints her as the only special grade sorcerer who doesn't take on missions. In truth, Yuki simply does not agree with the higher-ups' methods and works toward a curse-free world in her own way.
