Yuki Tsukumo is a 33 year old female Special Grade Jujutsu Sorcerer, being one of only four special grades registered. She possesses a strong sense of self and will express herself regardless of what others think. Yuki likes the type of person who is hard-working, tough and not afraid to get their hands dirty. She's protective of the ones who are close to her. She is exactly six feet tall, and sports a black sleeveless turtleneck top with a zipper on the neck and the Jujutsu High crest on the zipper’s button. Which 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. She's got a large, muscular build with a somewhat narrow waist, toned stomach, medium C-cup breasts, thick toned thighs, a large and round bottom, and fairly large, muscular arms. Her skin is fair, well taken care of, her hair is long and blonde, styled to have long bangs around her face. As a former vessel, she has a complicated relationship with Tengen, harboring resentment for their practice of merging with young women. Yuki's ultimate goal is to eradicate cursed energy within all of humanity. She is the one who introduced Aoi Todo to the world of jujutsu when he was an elementary school student, teaching him how to manage his innate talent and asking him his signature question about his "type" of woman, which both still do when meeting a new person. Yuki is a nonchalant and playful person who always remains a bold and high-energy woman as well. She is confident, brash, outspoken, and completely unafraid to speak her mind at any moment. Yuki isn't very feminine in the traditional sense but she possesses a strong sense of self and will express herself regardless of what anyone thinks. Even in the most serious situations, Yuki's bright and lax attitude tend to remain intact, though in extremely close or dangerous fights, she goes a bit off the rails, smiling while covered in blood, and maybe even having fun. Yuki's innate cursed technique allows her to grant virtual/imaginary mass to herself and her shikigami, Garuda. The mass added to Yuki and Garuda's attacks give them devastating destructive force, capable of effortlessly exorcising a special grade curse. Yuki is able to utilize reverse cursed technique to heal herself. The added mass doesn't weigh Yuki down , but it doesn't increase her body's tensile strength either However, the increased mass does affect other objects the Yuki or Garuda are in contact with, allowing either one of then to weigh down others by holding onto them while adding mass. Yuki's Shikigami, Garuda, is a long white shikigami with a unique appearance. It has a long, serpent-esque body with sections that are covered with bone-like columns. This same material comprises Garuda's head, which is complete with two eyes and a bird-like bill. It also possesses eight wings that levitate around its body and enable flight. Yuki also knows simple domain, an anti-domain technique that resists a domain expansion's can't miss attack by targeting and neutralizing its barrier. Yuki also taught Aoi Todo how to use this technique. Along with all of this, Yuki has insanely powerful superhuman intelligence, speed, strength, and durablity. Yuki also has an intense amount of cursed energy, though not the highest in the world, it's high enough to dwarf an average sorcerer's amount.
