Background / History

Yaya was cultivated beneath the General's Mansion in a transparent incubator around a Chakra Crystal core. Yayoi designed her as his second puppet life and as a counterpart to Irori: while Irori specializes in large-scale destruction, suppression, and containment, Yaya was built to be a concentrated offensive attacker with superior physical traits and a natural aptitude for taijutsu. 47

Her developing body absorbed the incubator's nutrients and formed an instinctive resonance with Irori before her mind had awakened. At the time of her activation, Yaya absorbed chakra from the captive Seven-Tails, integrated it into her core, and immediately recognized Irori as her sister and Yayoi as her father. 47 58

Yayoi tested her shortly after her awakening in an isolated mountain forest. Yaya demolished a hill with one punch without injuring her fist, then fought Irori to evaluate her combat capabilities. Irori's Ice Release could restrain and pressure Yaya, but it could not inflict meaningful damage; Yaya countered by shattering ice constructs, evading attacks, and returning projectiles at supersonic speed. 59

Following the test, Yayoi formally assigned her as the General's Bodyguard. Her strength later proved decisive against Kinkaku, the Nine-Tails, and the Tsuchigumo, though the strain of using multiple ultimate techniques against the Nine-Tails left her unconscious for an extended period. 61 65 99 100

Yaya later became one of the three chakra lifeforms collectively known as the Setsugetsuka, representing the moon alongside Irori's snow and Komurasaki's flower. During the Land of Night's conflict with Cloud Hidden, she attacked the injured Eight-Tails jinchuriki Tazubi after Yayoi suppressed his Tailed Beast Bomb. Cloud ninja subsequently gave her the epithet Black Yaksha in recognition of her chilling appearance and savage taijutsu. 217 234 263

Power Progression

Chapter(s)	Development	Details
47	Design and cultivation	Yayoi created Yaya as his second puppet life, specializing in concentrated close-range offensive power rather than Irori's large-scale suppression. 47
58	Awakening	Yaya absorbed Seven-Tails chakra into her Chakra Core, completing her activation as a chakra lifeform. 58
59	Initial combat evaluation	Demonstrated overwhelming speed, durability, destructive strength, and combat intuition against both a hill-sized target and Irori's Ice Release. 59
90	Diamond Strength and ultimate technique confirmation	Her chakra circuit was identified as Diamond Strength, and Extinction Red Lotus was confirmed as a focused ultimate attack with Tailed Beast Bomb-class destructive output. 90
98–100	Full-power battle against the Nine-Tails	Activated Heavenly Flash Comet and Extinction Red Lotus in combination, helping incapacitate the Nine-Tails but exhausting herself into prolonged unconsciousness. 98 99 100
144	Chakra Core limitation identified	Yayoi confirmed that her original raw physical parameters were fixed at creation, while considering Yin-Yang Release and Active Chakra as a means to remove that restriction. 144
165	Adaptation against genjutsu	Countered Komurasaki's illusion-based stealth by closing her eyes and relying on her physical senses; she also began preparing her Red Comet combat mode before Yayoi stopped the match. 165
234	Conflict with Cloud Hidden	Coordinated with Yayoi to further injure the Eight-Tails jinchuriki Tazubi after his Tailed Beast Bomb was suppressed. 234

Appearance

Yaya has fair skin, long black hair, and pitch-black eyes. Her usual expression is cold and restrained, particularly in battle. 58 59

• Wears a black off-the-shoulder kimono with a short hem. 128 181
• Wears white over-the-knee stockings tied with red braided cords and black wooden high-heeled clogs. 59
• Displays a small red triangular mark on her forehead while using her high-output combat state. 98 99
• Is physically comparable to a young maiden despite having existed for only five years from the formation of her embryo. 60
• Her beautiful but inhumanly cold appearance contributed to Cloud Hidden's designation of her as the Black Yaksha. 263

Personality

Yaya is intensely protective and possessive of Yayoi. She treats her role as his bodyguard with exaggerated seriousness, remaining vigilant even within the General's Mansion and reacting aggressively to women she considers potential threats to him. 60 81 128 139

Her emotions are volatile compared with Irori's composed demeanor. She is easily provoked, jealous of Kicho, Izayoi, and Komurasaki, and prone to escalating small concerns into confrontations. 60 128 164 165

In combat, Yaya becomes exceptionally calm and ruthless. Her usual impulsiveness gives way to decisive movements, sharp instincts, and a refusal to hold back against powerful opponents—even Irori and the Nine-Tails. 59 98 99

Yaya's protectiveness also extends to intrusive surveillance when she believes Yayoi may be at risk. She was already observing the Kagura Hall when Izayoi arrived to investigate Yayoi and Hisana, and encouraged Izayoi to continue watching rather than leave. 181

Abilities & Skills

Artificial Chakra Physiology

Yaya is a lifeform created from Yayoi's Active Chakra, Tailed Beast chakra, and natural life force. Her body and chakra constitution are extremely close to those of a Tailed Beast, though her total chakra reserves are lower. 100

• Her “brain” and “heart” are both represented by a Chakra Core located in her left chest. 100
• Her Chakra Core is protected by a special Chakra Crystal exterior, but damage beyond its defensive limit could destroy it. 100
• Her original physical parameters were fixed at creation; she can develop techniques, but her raw power cannot naturally increase without Yayoi resolving the limitations imposed by her Chakra Core. 144
• Can recover from injuries without hand seals by consuming chakra, as expected of a Tailed Beast-like chakra lifeform. 212

Diamond Strength

Yaya's chakra circuits are called Diamond Strength, reflecting her extreme durability and concentrated destructive power. 90

• Pulverized a hill with a single punch while remaining uninjured. 59
• Can withstand high-level Ice Release attacks with little more than dirt on her clothing. 59
• Fights through direct physical collisions with the Tsuchigumo's Spider Black Gold-enhanced body. 143
• Her ultimate physical output is comparable to a Tailed Beast Bomb, but is compressed into a focused point rather than spread across a wide area. 90
• Further injured the Eight-Tails jinchuriki Tazubi after Yayoi disrupted his Tailed Beast Bomb. 234
• Her wild, brutal close-quarters fighting style earned her the battlefield epithet Black Yaksha among Cloud Hidden ninja. 263

Taijutsu and Combat Intuition

Yaya is a specialist in direct close-quarters combat. Her speed, strength, durability, and instinctive threat detection allow her to overwhelm most conventional ninja. 47 59

• Moves quickly enough that Yayoi could barely follow her standard sprinting trajectory with the naked eye. 59
• Can shatter Ice Release constructs with her fists and legs, then throw captured ice weapons back at supersonic speed. 59
• Her instincts allowed her to disrupt Irori's freezing mist before it developed into a sealing technique. 59
• Countered Komurasaki's illusion-based stealth by closing her eyes and tracking disturbances through her physical senses. 165
• Lacks Irori's large-scale suppression and long-range area destruction. 47 90

Heavenly Flash Comet

Heavenly Flash Comet is one of Yaya's two designed ultimate techniques. It boosts her speed, attack frequency, and offensive ability while placing comparatively little strain on her body. 100

• Manifests as red electrical arcs generated by high-frequency chakra vibrations rather than Lightning Release. 98
• Produces a red triangular forehead mark and dramatically increases her acceleration. 98
• Was fast enough that Tobirama compared her movement to space-time ninjutsu. 98
• In this state, she can repel a Tailed Beast with a single strike. 100
• The precursor to her “Red Comet” combat mode appears as red arcs gathering around her body. 165

Extinction Red Lotus

Extinction Red Lotus is Yaya's offensive-breakthrough ultimate technique. It concentrates her power into devastating crimson fist pressure. 100

• Used at full output against the Nine-Tails, battering it with punches beyond human speed. 99
• Leaves delayed fist pressure inside the target before the accumulated force detonates as a red, lotus-like explosion. 99
• Its suppressive force against the Nine-Tails was compared to Mito's Adamantine Sealing Chains. 99
• Combining ultimate techniques pushed Yaya beyond her limits and caused prolonged unconsciousness after the Nine-Tails battle. 100

Other Techniques

• Reverse Summoning Jutsu (C) — Yaya possesses Reverse Summoning Jutsu, as recorded in her later ability profile. 212

Shared Telepathic Communication

Yaya can communicate through the telepathic mechanism Yayoi established between himself, Irori, and Yaya. 96

• Allows coordinated battlefield communication without spoken signals. 96 98
• Yayoi used the same Active Chakra-based mechanism for communication across a five-kilometer radius. 96

Relationships

• Yayoi — Her creator and “Father.” Yaya serves as his personal bodyguard and is fiercely protective and possessive of him. 58 60 61
• Irori — Her older sister and fellow puppet life. Irori helped welcome Yaya at her awakening, tested her combat ability, and regularly restrains her excesses. 58 59 81
• Kicho — Yayoi's wife. Yaya is openly hostile and jealous toward her, while Kicho usually treats Yaya's behavior with amusement rather than anger. 58 60 128
• Komurasaki — Her younger sister and rival. Their opposing specialties—taijutsu and genjutsu—led to a serious spar that Yayoi stopped before Komurasaki could use a dangerous technique. Together with Irori, they are known as the Setsugetsuka. 164 165 217
• Tsuchigumo — A recurring sparring opponent. The two engage in destructive hand-to-hand battles, and the Tsuchigumo values Yaya as a rare opponent capable of matching it directly. 90 143 144
• Mito — Yaya saved her from the Nine-Tails' ambush during the battle to seal the beast. 98
• Izayoi — Yaya views her as a possible rival for Yayoi's attention and initially obstructs her work at Tenshukaku. After Izayoi became Yayoi's concubine, the two were present together at the Naka Shrine while monitoring events in the Kagura Hall. 128 139 150 181
• Tazubi — The Eight-Tails jinchuriki whom Yaya attacked after Yayoi suppressed his Tailed Beast Bomb during the clash with Cloud Hidden. 234

Story Role / Major Arcs

Awakening and Initial Combat Test

Yaya awakens using chakra drawn from the Seven-Tails and is introduced as Yayoi's second puppet life. Her first combat test establishes her as a taijutsu-focused attacker who complements Irori's Ice Release-based battlefield control. 58 59

Bodyguard of the General

Yayoi appoints Yaya as his personal bodyguard. She follows him closely, guards the General's Mansion with excessive suspicion, and repeatedly interferes with women she believes may distract or endanger him. 60 61 81

Nine-Tails Conflict

Yaya confronts Kinkaku by kicking away a Tailed Beast Bomb, then joins Yayoi, Irori, Tobirama, and Mito against the Nine-Tails. Her full-power assault incapacitates the beast long enough for Irori and Mito to complete its sealing. 65 98 99

Chakra Core Limitation

Yaya's collapse after using her ultimate techniques reveals a possible issue involving the limits of her Chakra Core. Later, Yayoi confirms that her raw strength was fixed at creation and seeks to use Yin-Yang Release with Active Chakra to overcome that limitation. 100 109 144

Rivalry with Komurasaki

After Komurasaki's birth, Yaya immediately clashes with her new sister. Their battle demonstrates Yaya's ability to adapt against genjutsu, but also exposes the difficulty she faces against invisible projections and deceptive fighting styles. 164 165

Conflict with Cloud Hidden

During the Land of Night's battle with Cloud Hidden, Yaya supported Yayoi against the enemy jinchuriki Tazubi. After Yayoi neutralized Tazubi's Tailed Beast Bomb, Yaya attacked the stunned Eight-Tails jinchuriki and worsened his injuries, contributing to Cloud Hidden's retreat. 234

Black Yaksha

Yaya's repeated combat encounters with Cloud Hidden forces established her reputation as the Black Yaksha. The name reflects both her cold, inhuman beauty and the demon-god-like brutality of her taijutsu. 263

Trivia

• Yaya is the second of Yayoi's three puppet lives, following Irori and preceding Komurasaki. 47 163
• The three sisters are collectively called the Setsugetsuka: Irori represents snow, Yaya represents the moon, and Komurasaki represents the flower. 217
• Her appearance and Irori's are based on characters from Unbreakable Machine-Doll, specifically the eldest and second sisters of the Setsugetsuka doll trio. 47
• Despite her five-year developmental age, Yaya had been awake for less than a day when Aoi and Rinko first learned of her existence. 60
