Appearance

Nine Tails is a small, youthful Star Spirit who can appear deceptively cute and harmless. Her demeanor changes sharply in battle, where her eyes shine with starlight and she projects an imposing, queen-like presence. 512 813

• Snow-white animal ears. 396
• Star-like or galaxy-filled eyes when using power. 491 812
• Often floats freely rather than walking. 352
• Can manifest a spiritual body; for Star Spirits, the spirit is their core and vital point. 398
• Has appeared as a small golden statue after deliberately accelerating a transmutation effect. 400

Personality

Nine Tails is playful, willful, lazy, and easily bored. She enjoys teasing others—especially Accelerator—and can create trouble simply for amusement. 378 382 799 She views Star Spirits as pleasure-seekers and prioritizes being happy over overthinking larger concerns. 799

Despite this, she is highly perceptive in combat and understands both scientific and magical principles through her race's inherited knowledge. 491 When facing enemies, her usual childish manner gives way to a cold, bloodthirsty confidence. 512

She is deeply attached to Rimuru, protective of him, and openly possessive of her place at his side. 526 799 Her affection is not fully reciprocated romantically; Rimuru regards her as an invaluable companion or younger-sister-like figure. 534

Abilities & Skills

Star Spirit Physiology

As a Star Spirit of a divine race, Nine Tails possesses a naturally high life level. Star Spirits are expected to become Demigods upon adulthood, and her innate status allows her to contend with opponents beyond her formal level. 491 523

• Can float freely as a racial ability. 352
• Her spiritual body is her core and vital point. 398
• Possesses inherited knowledge from a civilization combining science and magic. 491
• Can potentially banish targets through Star Spirit talent. 543
• Spatial travel is described as one of her race's most basic abilities. 801

Spatial Manipulation

Nine Tails creates wormholes, traverses space, and pursues targets across dimensions. Her mobility makes her exceptionally dangerous against opponents attempting to flee. 372 514

• Opens wormholes for long-distance transport. 372
• Can create spatial turbulence capable of piercing spatial restraints, then execute a coordinate-based wormhole jump with effectively unlimited range if sufficient magic power is available. 801
• Can send attacks, particularly her spear, through space to strike from unexpected angles. 514 531
• Can track targets after they confirm coordinates. 812
• Spatial movement causes erosion and consumes energy; she avoids wasting it during difficult fights. 525

Stellar and Black-Hole Techniques

Nine Tails manipulates stellar energy, black-hole-like phenomena, and destructive psionic power. Her attacks are capable of threatening cities, planets, and high-level beings. 374 446 812

• Dark Star Burst — Creates a supernova-like explosion; destroyed the City of Magic. 374
• Star Burst — Condenses stellar power into a stellar-core-like explosion. 446
• Super Black Hole — A demigod-level technique used to counter Maria's attack. 541
• Annihilation Magic — Resembles a black hole but annihilates light, matter, and potentially souls rather than merely absorbing them. 818
• Can create a micro-universe to imprison a target. 475
• Can deploy a void-like electromagnetic cannon through long-range information-state display and transmission technology. 534

Temporary Arsenal Construction

Nine Tails can construct or manifest advanced armaments from an apparent arsenal, including virtual weapons and high-energy beams. 396 512

• Manifested countless illusory weapons from an information torrent formed of starlight. 512
• Uses azure psionic energy to produce beams that pierce layered defenses and melt the ground into deep craters. 512
• Can search for substitute equipment when a requested weapon is unavailable. 396
• Her arsenal may fail to locate an item if it is absent from her treasury or accessible supply platforms. 396

Matter-Energy Decomposition

Nine Tails can disintegrate matter by disrupting its structure and converting it into spacetime turbulence. 471

• Reduced Kakine Teitoku's Dark Matter beetle to dust with a touch. 471

Star Lance

The Star Lance is Nine Tails' divine artifact and preferred weapon. It was forged from the core of a destroyed star and remnants of a world-destroying event. 813

• Its divine power can pierce angelic protection that ordinary attacks cannot overcome. 512
• Enables relentless, multi-directional spear attacks through wormhole movement. 514
• Can tear space and leave destructive marks with fully unleashed strikes. 526
• In its proper manifested form, it can pierce layers of space and nearly strike the Ancient One. 810
• Nine Tails can project it and recall it after impaling a target. 811
• Using the artifact at full strength risks attracting the attention of Magic Gods or angels. 491

Cosmic Rhapsody

Nine Tails' ultimate move, used to trap and torment the Red Fox after he repeatedly escaped. 812 818

• Establishes a prison-like domain that suppresses space. 813
• Bound the Red Fox with starlight and prevented escape. 813
• Allowed her to subject a demigod-level opponent to Annihilation Magic. 818

Equipment / Weapons / Items

• Star Lance — Divine spear forged from a destroyed star's core and a world-destroying event's remnants. 813
• Star Power crystals — Used in combat; Nine Tails raised one while preparing to act against Kanzaki Kaori. 375
• Personal treasury/arsenal — Source of equipment and weapon-construction resources. 396

Relationships

• Rimuru Tempest / Jiang Rui — Friend, teammate, and the person to whom Nine Tails is most attached. She protects him instinctively and has romantic feelings for him; Rimuru values her as an irreplaceable companion. 357 446 526 534
• Accelerator — Frequent target of her teasing and provocations. She repeatedly countered his vector manipulation and kidnapped a Misaka Sister to draw him out. 357 382
• Lilith — A fellow powerful woman in Rimuru's group. Nine Tails sees Lilith as a rival for Rimuru's attention, while Lilith is more curious than hostile toward her. 799
• Reivinia Birdway — Ally in several high-level conflicts; Reivinia recognizes the possibility of Nine Tails possessing a divine bloodline. 475 541
• Yinyin Qingcao — Nine Tails acts as an older-sister figure and enjoys impressing her with Star Spirit knowledge. 491
• Monk — Faced Nine Tails in a serious battle involving the Six Paths Rock Pillars; Nephtys ultimately captured Monk after the pillars were destroyed. 525 526
• Red Fox — Pursued and trapped by Nine Tails after his repeated attempts to escape or retaliate against Rimuru. 810 812 818
• Phoenix — Opponent whose overwhelming strength forced Nine Tails to break through temporarily to Sequence 3. 878

Story Role / Major Arcs

Academy City and Kanzaki Kaori Conflict

Nine Tails first becomes Rimuru's friend after fighting alongside him and saving him from Accelerator. Their alliance develops into a close partnership. 357 She supports Rimuru during the pursuit of Kanzaki Kaori, using portals for mobility and Dark Star Burst to destroy the City of Magic. 372 374

During the later confrontation with Kanzaki, Nine Tails shows both inexperience and determination to protect her friends. 375 She subsequently becomes a regular member of Rimuru's household and team, participating in social gatherings while continuing to antagonize Accelerator for fun. 378 382 383

Academy City Escalation

Nine Tails assists in missions involving Aureolus, Kazakiri Hyouka, and other threats. She manifests her spiritual form during the bonfire gathering after Aureolus's defeat. 403 Against Kazakiri, she identifies the principle behind Angelic magic and uses her knowledge to support the team. 491

Her destructive capability becomes increasingly visible during the conflict with Kerrisa and Sylvia, where her attacks pierce angelic defenses and her arsenal provides devastating orbital support. 512 514

Magic God Conflict

Nine Tails fights Monk while Rimuru confronts Niangniang. She destroys Monk's giant hand, adapts to the Six Paths Rock Pillars, and carefully conserves energy due to the cost of spatial movement. 525 Her concern for Rimuru intensifies when Niangniang threatens him, and she is prepared to sacrifice herself for his safety. 526

Return to the Extraordinary Space

After completing her trial, Nine Tails returns to Rimuru's side and immediately clashes with Lilith over her perceived status. 799 Her human-equivalent age is stated to be approximately fourteen to sixteen, despite her mature appearance among her own people. 800

Marvel World Arc

Nine Tails accompanies Rimuru into the Marvel world and helps explain the danger posed by higher civilizations. 804 During the confrontation at Kamar-Taj, she deploys the Star Lance against the Ancient One and later repeatedly pursues the Red Fox across dimensions. 810 812

She activates Cosmic Rhapsody to trap the Red Fox, then uses Annihilation Magic against him after he is captured. 812 818 When Phoenix attacks Rimuru's group, Nine Tails temporarily reaches Sequence 3 and uses Star Dome Leap to facilitate the others' escape. 878

Trivia

• Nine Tails considers throwing a spear improper for a warrior, but Earth culture and Jiang Rui's influence changed her view of the tactic. 515
• She can be highly status-conscious within Rimuru's group, privately wanting her position as his “main consort” to remain secure. 799
• Although others regard her as Rimuru's faction's highest-authority powerhouse, she would often rather keep eating than intervene in a fight. 834
• Her battlefield knowledge and manner can become markedly regal when negotiating with other powerful groups. 837
