Yuki Tsukumo

Biodata

Personality

Yuki is carefree, forward, and theatrical. Upon meeting Yue Liusi, she immediately examines his physique and squeezes his shoulder, prompting him to call her behavior creepy. She had also hoped to make a dramatic entrance in Shibuya and enjoy the younger sorcerers’ admiration 21.

Her teasing manner coexists with genuine concern. She warns Yue against impulsively challenging the Higher-Ups, then openly supports him once he commits to acting. After witnessing his overwhelming strength against Yuta Okkotsu, her embarrassment over having underestimated him quickly gives way to relief that he is their ally 26 29 32.

Yuki is intensely curious about unfamiliar powers and their wider applications. Mai Zenin’s improvement interests her as a possible breakthrough for other sorcerers, while Suguru Geto’s reincarnation prompts questions about death and his present condition. She wants greater strength because it would allow her to accomplish more, rather than treating power as an end in itself 42 47 48.

Abilities & Skills

Star Rage

Yuki possesses the cursed technique Star Rage, which Yue Liusi expresses interest in studying 48.

• She tests Yue’s chakra using her own technique and recognizes its threefold nature 47.
• She seeks the same lasting access to chakra that Mai receives, hoping to experience her technique fully unleashed. Yue postpones the request; no enhancement is confirmed 48.
• The supplied chapters do not demonstrate Star Rage’s combat effects 47 48.

Reflexes and Combat Assessment

• Evasion: Dodges a thin red slash sent toward her during Yue’s assault on Jujutsu Headquarters; the attack slices through a nearby house 29.
• Energy-control analysis: Deduces that Yue compresses his technique’s power into a line and stabilizes it with cursed energy. She judges his precision comparable to Satoru Gojo’s and wonders whether his eyes possess a special trait like the Six Eyes 29.
• Threat recognition: Recognizes Hajime Kashimo as a strong sorcerer, despite Shoko’s skepticism toward his claim of being the strongest from four hundred years earlier 46.

Instruction and Technical Insight

• Teaching: Aoi Todo is identified as her pupil. Yue later entrusts her with Mai Zenin’s combat training 21 39.
• Practical training: Takes Mai into several battles and observes her newly expanded use of Construction 47.
• Chakra analysis: Identifies Yue’s energy as a “trinity.” This observation helps him understand his perception of innate techniques through the body, soul, and brain 47.
• Indirect contribution: Yue credits her insight with helping him complete the fusion of Nine-Tails Chakra Mode and Lava Release Chakra Mode 48.

Story Role / Major Arcs

Shibuya Aftermath

Yuki arrives as Special Grade reinforcement after Kenjaku has escaped with Uraume. Surprised by Yue Liusi’s strength, she questions him about the apparent return of Suguru Geto. Yue explains that Kenjaku has occupied Geto’s body and acquires cursed techniques through possession 21.

She then learns that Kenjaku has prepared remote Idle Transfiguration, the incarnation of ancient sorcerers, and the release of numerous cursed spirits. Her expression darkens at Yue’s warning that Tokyo will return to the conditions of the Heian Golden Age 21.

Confrontation with the Higher-Ups

Yuki brings news that Tengen may know how to unseal Satoru Gojo and understand Kenjaku’s plans. She proposes having Yuji Itadori meet Yuta Okkotsu first to deceive the Higher-Ups, followed by a visit to the Tombs of the Star Corridor 25.

Privately, she informs Yue of his renewed death sentence and Megumi Fushiguro’s appointment as Zenin Clan head. Although she cautions Yue against underestimating the Higher-Ups, she ultimately supports his advance on Jujutsu Headquarters 25 26 29.

After the purge, Yuki recognizes the intent behind Yuta’s public challenge to Yue and stays to watch. Yue’s Kurama Mode leaves her stunned by how far his strength exceeds her expectations 31 32.

Culling Game Operation

At Shoko Ieiri’s birthday party, Yuki raises concerns about their limited manpower and asks Yue for a plan. When he insists neither manpower nor planning is necessary, she agrees to follow his lead 34.

Before the colony operation, Yue assigns her to protect Shoko, who will coordinate their efforts, and train Mai. Yuki subsequently joins them in Tokyo No. 2 Colony, where she witnesses the reincarnation of Jogo, Suguru Geto, and Toji Fushiguro 39 40.

During Jogo’s confrontation with Yue, she moves the others away before Maximum Technique: Meteor falls. She later understands Yue’s approach to controlling the colony: using overwhelming strength to enforce a direct proclamation 42 43.

Investigating Chakra

After training Mai, Yuki presses Yue to explain her sudden improvement, hoping the method could benefit many other sorcerers. He warns that it would be difficult to distribute widely but allows Yuki to experience his chakra directly 47.

Her analysis helps Yue understand his ability to study innate techniques. She then witnesses him reproduce Construction and complete his fusion armor. When she requests an enhancement like Mai’s, Yue defers the discussion; her subsequent appeal to Shoko is also unsuccessful 47 48.

Relationships

• Yue Liusi — Ally and subject of persistent curiosity. She supports his challenge to the Higher-Ups, follows his Culling Game leadership, and seeks access to his chakra 29 34 47 48.
• Shoko Ieiri — Friend and assigned protectee. Yuki teases her about Yue and tries to encourage their relationship after learning that he prefers the gentle older-sister type 34 38 39.
• Aoi Todo — Her pupil; she uses his build as her point of comparison when examining Yue’s physique 21.
• Mai Zenin — Combat trainee. Mai’s improved performance leads Yuki to investigate the broader potential of Yue’s chakra 39 47.
• Suguru Geto — An acquaintance whose reincarnation fascinates her. His refusal to entertain her questions irritates her, and she approvingly watches Shoko kick him after his teasing remark 42.
• Tengen — Coordinates a proposed visit to Tengen and remarks on Tengen’s unusual trust in Yue 25 27 29.
