Yuki Tsukumo

Biodata

Power Progression

Background / History

Yuki was formerly a Star Plasma Vessel and already knew about Tengen before joining Kaneki’s mission. Once Choso guided the group to the Cursed Warehouse, she knew the remaining route to the Tombs of the Star Corridor 13 15.

Her goal is to eliminate cursed energy and create a peaceful world without cursed spirits. This directly opposes Kenjaku’s plan to optimize cursed energy by merging humanity with Tengen, an explanation that leaves her furious 12.

Kaneki’s account of the future identifies Yuki as someone who would die fighting Kenjaku while protecting Tengen. Tengen explains that, in that future, her response to Kenjaku’s open-barrier domain left Yuki exposed to its sure-hit effect. This is a foreseen outcome, not Yuki’s fate in the altered events shown here 10 14 15.

Appearance

• Hair: Blonde 10.
• Face: Described as pretty, combining strength with softness 9.
• Height: Taller than Kaneki, whose height is stated as 171 centimeters 38.

Personality

Yuki normally has a carefree manner, but becomes direct and urgent when the situation demands it. After learning that Kenjaku could obstruct Gojo’s release, she immediately pushes the group to find Tengen; upon meeting Tengen, she asks outright for the Back of the Prison Realm 13 15 38.

She is protective of her allies and willing to make painful sacrifices. She objects to Kaneki and Choso facing Kenjaku without sufficient support, and gives Kaneki her right arm to help him acquire Star Rage—but only after asking what he intends to achieve 13 14.

Her trust in Kaneki rests on evidence rather than his claims alone. She finds his predictions plausible and learns from Nanami and the others that his warnings saved their lives 12.

Abilities & Skills

Star Rage

Star Rage adds virtual mass to Yuki or her technique-derived shikigami, producing exceptionally powerful physical attacks 13.

• Heavy strikes: Turns ordinary punches into blows with vastly greater impact. Against Kenjaku, she breaks both of his blocking arms and sends him flying more than a hundred meters 13 45.
• Controlled mass: The increase depends on her conscious will 13.
• Restricted targets: It affects only herself and the shikigami formed from her technique, not ordinary surrounding objects 13.
• No matching durability increase: Greater mass does not automatically make her body tougher 13.
• Black Hole potential: Accumulating virtual mass to an extreme can produce a black hole. The self-destructive version associated with Yuki could potentially affect the entire world 35 48.
• Precision limit: She cannot perform Kaneki’s proposed controlled black-hole application through a small cursed-tool shikigami; she recognizes that his much finer cursed energy control may make it possible 35.

Garuda

Garuda is a mechanical-looking, serpentine shikigami resembling a chain of vertebrae. Yuki creates it by turning her cursed technique into a cursed tool and can summon it at will 13.

• Mass-enhanced combat: As Star Rage’s only eligible target besides Yuki, Garuda can carry the technique’s virtual mass 13.
• Thrown attacks: Pierces the Elephant God in Shibuya and later wounds Tachibana Mio during the domain battle 8 21.
• Whip attacks: Yuki swings it as a long whip against Kenjaku 45.
• Independent support: Breaks ice trapping allies and holds back Uraume and Tachibana Mio while Yuki attacks Kenjaku 20 22.
• Persistence during burnout: Garuda does not disappear when Yuki enters cursed technique burnout, provided she still has cursed energy 21.

Domain Expansion: Star Balance Domain

Yuki’s domain manifests a star-studded environment. Its specific sure-hit effect is not described in the supplied passages 20.

• Domain clash: Reaches a stalemate with Tachibana Mio’s Court of Words That Bind Fate 20.
• Maintenance limit: Collapses when Kenjaku’s amplified gravity injures Yuki badly enough that she cannot sustain it 21.
• Barrier adjustment: Learns to reverse its internal and external conditions, a countermeasure intended to buy time against an open-barrier domain 11 28 37.

Reverse Cursed Technique

Yuki can regenerate lost limbs and recover from severe injuries 13 21 47.

• Regrows the right arm she voluntarily gives Kaneki 13.
• Heals while inside Okkotsu’s domain after he confirms that its sure-hit effect will not target her 21.
• Regenerates the hand severed by Sukuna and returns to battle 46 47.

Anti-Domain Techniques

• Simple Domain: Uses it against Kenjaku’s attacks and Womb Profusion. During the later defense of Tengen, it lasts long enough for Tengen to dismantle the surrounding barrier before it collapses 21 45 46.
• Hollow Wicker Basket: Masters it before the soul-exchange training 37.
• Falling Blossom Emotion: Attempts it during training in Kaneki’s body; mastery is not confirmed 38.

Soul Knowledge and Black Flash

• Soul-targeting methods: Possesses knowledge that could help Itadori precisely sever the boundary between Sukuna’s soul and his vessel’s soul 11.
• Written research: Kaneki uses her notes to reach Tsumiki Fushiguro’s consciousness and restore her will to live 45.
• Black Flash: Lands several Black Flashes on Todo while inhabiting Kaneki’s body, accelerating the engraving of cursed techniques into his brain 38.

Relationships

• Ken Kaneki — Ally and training partner. She gives him her arm to acquire Star Rage, agrees to exchange souls for training, and permits him to use her body to make Mahoraga adapt to her technique 13 37 38 48.
• Aoi Todo — Her student. Their coordination lets her bypass Kenjaku’s gravity with Boogie Woogie; Todo also swaps her to safety after Sukuna severs her hand 45 46.
• Yuta Okkotsu — Fellow Special Grade Sorcerer and combat partner. He supports her against Kenjaku, protects her while she heals, and teaches her domain-condition reversal 20 21 28.
• Choso — Ally in the defense of Tengen. They combine his blood attacks, her physical offense, and Todo’s position-swapping against Kenjaku and Uraume 38 45.
• Tengen — Connected through Yuki’s former status as a Star Plasma Vessel. Yuki obtains the Back of the Prison Realm from her and ultimately remains to protect her 13 15 16.
• Kenjaku — Enemy whose plans fundamentally oppose her own. He is responsible for her predicted death, and she repeatedly confronts him in the altered timeline 12 14 23 45 47.

Story Role / Major Arcs

Shibuya Intervention

• Garuda interrupts the Elephant God’s technique, but Yuki arrives after Kenjaku has destroyed Kaneki’s left arm and part of his torso 8.
• She attempts to stop Kenjaku leaving; his swarm of cursed spirits obstructs her, allowing him to escape with Uraume and the Prison Realm 9.

First Defense of Tengen

• Receives the Back of the Prison Realm and participates in planning around Kenjaku’s open-barrier domain 15 19.
• Clashes domains with Tachibana Mio, suffers severe injuries, and heals before rejoining the assault 20 21 22.
• Kenjaku conceals a miniature Uzumaki behind cursed spirits. Yuki avoids a direct hit to her vital organs but loses a chunk of her left flank 23.
• Survives the encounter when Kenjaku and his allies withdraw under cover of Uraume’s ice 23.

Training Before the Culling Game

• Helps develop the group’s countermeasures through soul knowledge, barrier training, and soul exchange with Kaneki 28 37 38.
• Her training in Kaneki’s body contributes to Star Rage and Ten Shadows becoming permanently engraved in his brain 38.
• Remains with Maki, Choso, and Todo to guard the Tombs of the Star Corridor while Kaneki’s team seeks Angel 38.

Renewed Assault on the Tombs

• Fights Kenjaku with Choso and Todo, using their coordinated attacks to force him to expand Womb Profusion 45.
• Emerges unscathed when Tengen dismantles the Emptiness Barrier just before her Simple Domain fails 46.
• Sukuna interrupts her attack on Uraume and severs her hand. Todo rescues her, and she regenerates the limb 46 47.
• Returns to pressure Kenjaku alongside Maki while Gojo, Kaneki, and Mahoraga fight Sukuna 47.
