Yuki Tsukumo

Yuki Tsukumo is a character in the Jujutsu Kaisen series. She is one of only four special grade jujutsu sorcerers. 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.

Appearance
Yuki is a 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 eyes with thin eyebrows and pronounced eyelashes.

She has sported a few different outfits but currently appears in a sleeveless, dark-colored vest reminiscent of female Chinese martial artists' attire. The vest is tucked into light-colored high wasted jeans that cover most of her stomach area. She finishes this outfit with a pair of dark boots and red baggy cargo pants.

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 dark sleeveless turtleneck, light-colored jeans, and heeled 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.

Personality
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 ladylike 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 remain intact.

The outspoken Aoi Todo inherited his signature phrase, "What kind of girls do you like?" from her. She asked him this when he was just a little kid in grade school. She was impressed by how a strong boy was bored after beating someone older than him. She took Todo under her wing and supplied him with a whole new avenue for excitement. Yuki's own personal type is a hard-working, tough-guy who isn't afraid to get his hands dirty.

In 2007, Yuki sought out Satoru Gojo to speak with someone of her rank, to who she could relate. She met Geto, and found out from him that she had built a reputation as a lazy sorcerer who bums around overseas. Yuki comically sulked when she heard but quickly revealed she couldn't care less about what Jujutsu Headquarters thought of her. Yuki wants to exterminate curses completely and she feels like Jujutsu Headquarters is only treating the symptoms.

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 continued her conversation with "Geto" eleven years later in Shibuya where she elaborated on her ideals surrounding the jujutsu world. She believes that the next stage of humanity involves breaking away from cursed energy completely. Yuki rejected Kenjaku's method of turning humans into resources that would create widespread suffering, declaring that to be far from the world she pursues.

Yuki dislikes Kenjaku because he's coy and condescending. Their conversation quickly annoyed Yuki and she was ready to beat him up for his attitude. Despite her personal feelings, Yuki prioritized protecting the younger sorcerers and eventually returned them all to Jujutsu High herself. Yuki empathized with Yuji's situation following the Shibuya Incident and apologized for waiting until it was too late to act. She claimed they weren't necessarily allies and distinguishes herself as a humble beauty fighting cursed spirits in her own way.

As a former Star Plasma Vessel, Yuki has a particularly complicated relationship with Tengen. She agreed to protect him 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.

While her allegiances are mostly to herself, Yuki is a supportive comrade who uses her outspoken personality to encourage others. She and Choso weren't overly familiar with each other at first but Yuki listened to Choso express himself in an emotional conversation where she offered support. Yuki was also concerned for Choso's well-being when he offered to be the vanguard against Kenjaku. When Choso made Kenjaku reveal his abilities, Yuki revered Choso and even called him "big brother", a role that defines Choso as a person. Yuki likes the rough men like Choso and dislikes Kenjaku, who she feels the need to "beat into shape" until he's humbled and becomes her type. When Choso attempted to sacrifice himself for Yuki, she encouraged him to live on and had Tengen remove him from the fight.

Yuki is a confident fighter who remains calm and retains her playful demeanor in life-or-death battles. She taunted Kenjaku throughout her fight and smiled through gruesome injuries, always willing to remind him that she only likes the rough type. Even in her final moments, Yuki smiled and goaded Kenjaku as she attempted to take him down with her.

Abilities and Powers
Overall Skill Level: Yuki is an extremely powerful fighter, one of only four special grade sorcerers who possesses incredibly unorthodox abilities. Jujutsu Headquarters knew next to nothing about Yuki's powers despite designating her special grade but she has shown up for her allies and showcased her abilities against some of the strongest opponents available.

Yuki possesses elite combat instincts and is highly talented in jujutsu, capable of using her innate technique, barrier techniques, and domain expansion. She's also fully capable of instructing students and fostering elite talent despite not being a teacher at Jujutsu High. Yuki introduced Aoi Todo to jujutsu and mentored him into the exceptional grade 1 sorcerer he's flourished into. Her training was extremely grueling, enough so to physically scar Todo for life. Todo has shown the fruits of her imparted knowledge time and time again, including learning to use Simple Domain from her.

Yuki displayed her own strength when she effortlessly repelled Uraume's Icefall technique using only Garuda. Uraume had overpowered a large group of sorcerers on their own who were all saved by Yuki's intervention. Yuki used her full strength against Kenjaku and effortlessly exorcised one of his special grade curses with her first attack. Her second attack sent Kenjaku flying and made him question whether he could even tame the wild beast known as Yuki Tsukumo.

Kenjaku's domain expansion severely injured Tsukumo only because she chose to rely on Tengen's help and their countermeasures had a severe miscalculation. Yuki's simple domain couldn't stand up to Kenjaku's domain but using her domain would've likely ended with a different outcome. Yuki continued fighting despite her injuries, and with Choso's help, she drove the curse user into a corner.

Despite initially believing Choso would only hold her back, Yuki fought effectively alongside Choso even while her body was mangled and proficiently utilized reverse cursed technique to heal herself while Choso was holding their opponent off. Once healed, Yuki quickly regained momentum with her pure destructive power but Kenjaku outwitted her and dealt an unexpected fatal blow. Yuki fought to the end and used her innate technique to transform into a black hole with the potential to destroy the world. She suppressed its power using her will and prevented a catastrophe, impressing even the callous Kenjaku.

Master Hand-to-Hand Combatant: Yuki is primarily a close-quarters combatant who supplements her martial arts with her innate technique to unleash devastating attacks. In her first hand-to-hand exchange with Kenjaku, she was able to use a single punch to literally break through his guard and send him flying. Yuki kept Kenjaku, an excellent taijutsu user, on the defensive throughout most of their hand-to-hand combat exchanges. Even with a broken arm and numerous other injuries, Yuki was able to pressure Kenjaku with flurries of kicks and other improvised attacks. A fully healed Yuki easily outmaneuvered Kenjaku at close range and nearly defeated him.

Immense Endurance: Yuki is exceptionally durable for a human being and has a high pain tolerance. She suffered a direct hit from Womb Profusion that dealt her a serious head injury as well as a completely shattered right arm. Not only was Yuki able to move despite her injuries, but she kept her innate technique active and fought Kenjaku on even terms in hand-to-hand combat. While her body quickly reached its limit due to her injuries, Yuki fought through them and continued to use her mangled body to pressure Kenjaku alongside Choso. Yuki even managed to move and activate with her body bifurcated, fighting until the very end.

Great Tactical Intellect: 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 is taken.

As a testament to her jujutsu-related knowledge and intuition, Yuki was able to recognize Ganesha was a cursed spirit foreign to Japan with a single glance. It only took a single activation for Yuki to figure out Kenjaku could manipulate gravity. Further observation of Kenjaku's technique allowed Yuki to figure out its effective range as well as the time needed between activation intervals.

Yuki worked with Tengen to formulate a multi-layered plan to deal with Kenjaku that was nearly successful in several facets. Although the second phase of their plan was miscalculated and Yuki didn't escape Kenjaku's domain unharmed, she knew she needed to keep fighting through her physical trauma so Choso could ambush him in the next phase. When Kenjaku survived the ambush, Yuki quickly deduced how he managed to avoid a fatal blow. She also recognized he would've died if her technique was at full power and that he was still cornered regardless.

While Yuki can keep pace in a cerebral battle with an incredibly experienced sorcerer such as Kenjaku, even she makes mistakes. Not only did she underestimate Kenjaku in her strategy with Tengen, but when Yuki attempted to exploit the time lag in Kenjaku's ability to manipulate gravity, she assumed Star Rage could power through any resistance from Cursed Spirit Manipulation. While this was a safe assumption, it was reckless and turned out to be incorrect, which Yuki herself realized and admitted.

Even in defeat, Yuki quickly improvised a maneuver to take her opponent down with her in a last-ditch effort to do what was necessary for the greater good.
