Kumara is a multi‑tailed fox spirit and high‑class magic beast in That Time I Got Reincarnated as a Slime, formerly serving under Clayman as Ninehead and later reborn as the divine beast‑type upper Holy-Demonic Spirit “Heavenly Star Nine-Tailed Fox,” one of Rimuru Tempest’s Twelve Guardian Kings.
Kumara is a rare member of the Ninehead species, a legendary multi‑tailed fox monster.
She begins as one of Clayman’s “Five Fingers,” later becomes a floor guardian of Ramiris’s labyrinth, and finally awakens as the “Illusory Beast King.”

Voice Actor (Anime): Sayumi Suzushiro
Kumara’s original form is that of a small fox-like monster with multiple tails, small enough to fit in a person’s arms.
In this child fox form she looks like an adorable pet, which sharply contrasts with the power she actually wields.
When she transforms into a humanoid, she appears as a beautiful fox‑kin girl with black hair tinged with brown and golden eyes.
Her mannerisms and old‑fashioned, refined speech give her a calm, elegant aura.
As she grows under Rimuru Tempest and trains as a labyrinth guardian, she develops a “grown‑up” adult form.
In this mature form she is described as a peerlessly beautiful, country‑toppling femme fatale whose charm borders on supernatural.
After her awakened evolution into a Divine Fox, her beauty and charisma further intensify.
Her hair color changes from brown‑shaded black to radiant gold, symbolizing her new status and power.
On the surface, Kumara is bright, friendly, and easy to get along with, often acting as a mood maker.
She enjoys interacting with people in Tempest and at the Ingracia academy, where she studies alongside human children such as Chloe Aubert.
However, true to her fox nature, she is also sly, calculating, and not nearly as innocent as she looks.
She can be quite manipulative when it benefits her, especially when she wants special treatment from Rimuru Tempest.
Kumara is very competitive and strongly dislikes losing, both in battle and in status.
This makes her clash frequently with Apito, whose straightforward and warlike personality is the complete opposite of Kumara’s.
Despite their frequent friction, Kumara and Apito recognize each other’s strength and end up as grudging rivals who push one another to improve.
Kumara openly acknowledges Zegion as someone she cannot hope to match, honestly accepting him as the strongest of the labyrinth’s guardians.
Her loyalty to Rimuru Tempest runs deep and is flavored with possessiveness and a desire to be “the one he dotes on the most.”
Underneath her happy life in Tempest, she still harbors a burning hatred toward the Eastern Empire that destroyed her homeland, waiting for a chance to take revenge.
When she wants something from Rimuru Tempest, she is shamelessly tactical.
She deliberately reverts to her younger, cuter form, looks up with pleading eyes, and “asks sweetly,” fully aware of how hard it is to say no to her.
Origin and the Fall of the Hidden Monster Village
Kumara was born in a hidden village called the Hidden Monster Village (Youmaguo), a secret settlement of non‑human beings near the Eastern Empire.
Her mother, Quo, was the village chief and a powerful fox demon comparable to a demon lord seed in strength, yet also a gentle leader who maintained the village as a peaceful sanctuary.
Because the village gathered many strong monsters, the Eastern Empire saw it as a potential threat.
The Empire launched an invasion, and although both sides suffered huge losses, the Empire ultimately destroyed the village.
Young Kumara, identified as an ultra‑rare Ninehead, was captured alive as a valuable specimen.
Information about her reached Clayman, who obtained her from the Empire and brought her into his service.
Under Clayman as Ninehead
Clayman told Kumara about the Empire’s role in destroying her home, fueling her hatred and helping her grow in power.
Driven by revenge and grief, she developed more tails and rose all the way to become one of Clayman’s “Five Fingers,” specifically the “Thumb.”
At the same time, Clayman feared her potential.
To ensure she could not betray him, he branded her with the curse “Demon Dominate,” a domination spell that compelled her obedience regardless of her will.
At this stage, Kumara did not yet have the power or class to transform into a human.
Her usual form was just a small, many‑tailed fox beast, usually about house‑cat size and often carried in Clayman’s arms.
In battle, she could enlarge herself into a massive three‑tailed fox monster.
Even in this “still incomplete” state, her magicule quantity rivaled pre‑forced‑awakening Clayman, marking her as an incredibly gifted monster.
Walpurgis and Rescue by Rimuru Tempest
Kumara accompanied Clayman to the Demon Lords’ banquet, Walpurgis, as one of his attendants.
Clayman intended to use the event to destroy Rimuru Tempest, but his preparations collapsed under Rimuru Tempest’s careful countermeasures.
When the debate among the demon lords stalled, Guy Crimson proposed settling matters through battle under his “might makes right” philosophy.
This escalated into a conflict involving not only the demon lords but their subordinates as well.
Kumara, under the control of Demon Dominate, was forced to fight Ranga, Rimuru Tempest’s shadow wolf.
However, Ranga had already received the blessings of an awakened demon lord and massively outclassed her.
Caught between Ranga’s overwhelming power and her own struggle against Clayman’s curse, she was quickly driven to exhaustion and collapsed.
Ranga, sensing something wrong, brought her before Rimuru Tempest, who identified and removed Clayman’s domination spell.
After Clayman’s defeat and destruction, Kumara was freed from his control.
Rimuru Tempest took her into Tempest, and she spent some time under Ranga’s care, slowly recovering her health and original cheerful personality.
Joining Tempest and Becoming Kumara
Grateful to Rimuru Tempest and Ranga for saving her, Kumara pledged her allegiance to Rimuru Tempest.
Rimuru Tempest then formally named her “Kumara” (meaning “Nine Demonic Radiance”), causing her to evolve and gain nine tails.
At this point, she came under the protection of the Monster Federation Tempest.
She also began to integrate into Tempest’s society, meeting its people and slowly building real friendships instead of coerced ties.
Ranga later recommended her as a floor guardian for Ramiris’s massive underground labyrinth.
Kumara accepted, becoming the guardian of Floor 90, while her separated tails served as area guardians for Floors 81–89.
Life as a Labyrinth Guardian and Student
As Kumara’s power continued to grow, her tails developed independent wills and split off into separate entities.
This sudden division greatly reduced her own magicule pool, leaving her with an almost childlike body and drastically weakened power.
Rather than treating this as a problem, Rimuru Tempest cleverly turned it into an opportunity.
He enrolled her in the Ingracia Kingdom’s academy, the same school where he had worked as a teacher, so she could receive “re‑education” alongside human children.
Kumara thus lived a double life: labyrinth floor guardian in Tempest and schoolgirl in Ingracia.
During this time, she befriended children like Chloe Aubert, attended classes, and matured emotionally while slowly mastering her powers.
Through her experiences in Tempest and at the academy, Kumara grew from a traumatized tool of Clayman into a more balanced, socially adept person.
Her body developed from a little girl form into a beautiful young woman, and she eventually rose to stand among the “Ten Lords of the Labyrinth.”
Her adult form was praised as having the beauty of a country‑toppling courtesan, and she became confident in using this appearance strategically.
This form later plays a key role when she confronts those responsible for her mother’s death.
Revenge Against Kanzus of the Eastern Empire
During the Eastern Empire’s invasion of the labyrinth, Kumara finally faced Kanzus, the man responsible for destroying her homeland and killing her mother Quo.
Kanzus was a cunning enemy equipped with the unique skill “Plunderer,” which allowed him to summon Quo and her tails, now turned into his weapons.
Using Quo’s five tails as independent fighters, Kanzus launched wave after wave of attacks that drove Kumara into a temporary corner.
Emotionally, the fight was brutal: she had to battle the image and power of her beloved mother wielded by the enemy who killed her.
But Kumara had already surpassed the level of her mother’s five tails.
She recalled and unified all eight of her own tails, gathering them back into herself and unleashing her ultimate technique.
In her nine‑tailed state, she used Nine-Tail Continuous Slash, a devastating finishing move.
This attack cut through Kanzus and ended their long‑standing grudge, allowing her to finally avenge her mother and her destroyed village.
Notably, by this time Kumara could shift into her adult, bewitching form at will.
She used this glamorous appearance when she slew Kanzus, making her revenge not only powerful but dramatically fitting.
Awakening and Becoming the Illusory Beast King
During the “Clash of Dragons and Demons” arc, Rimuru Tempest prepared for an upcoming war against the heavens.
To strengthen his key subordinates, he distributed a massive stock of 1.2 million souls stolen by Shion’s ultimate skill partner Shion’s support entity Ciel from Guy Crimson.
Kumara received 100,000 souls from Rimuru Tempest and used them to undergo an awakened evolution.
She ascended from Heavenly Star Nine Beast to Divine Fox, an upper Holy-Demonic Spirit of the Earth Spirit Beast type.
With this evolution, she gained the ultimate gift Illusory Beast King (Bahamut).
This ability integrated and elevated her existing skills, greatly enhancing her combat capabilities and control over her tails.
At the same time, Rimuru Tempest granted her the title Illusory Beast King (Chimera Lord).
She was formally recognized as one of the Twelve Guardian Kings, elite protectors who stand just under Rimuru Tempest and his topmost lieutenants.
Before her awakening, Kumara already exploited an interesting loophole.
She had Rimuru Tempest announce and “call” the names of her eight tails, granting them a naming‑like power‑up, similar to how Gabiru’s loyalty shifted through re‑naming.
After her own awakening, the benefits of the tails’ empowerment fed back into her.
She gained full, absolute control over all eight tails, and their combined strength further amplified her own.
Although among the Twelve Guardian Kings she is considered in the lower ranks in terms of battle experience, her raw specs and potential place her near the top tier.
She continues to train, filling in her weakness in experience with repeated simulations and battles.
Clayman Revenge Spin‑Off (Alternate Scenario)
In the spin‑off work Clayman Revenge, an alternate storyline is presented.
In this version, Clayman intervenes before Kanzus can kill Quo, leading to Kumara’s entire clan being taken into Clayman’s service instead of being wiped out.
Because Quo survives in this timeline, Kumara remains in a child fox state and sleeps for long periods.
When Clayman later attempts to use her original name Ninehead, stopping halfway through, Kumara responds faintly even in her slumber, hinting at her latent connection to him.
This spin‑off changes the timing and circumstances of her meeting with Clayman but keeps her as a rare and prized Ninehead.
It provides an alternate emotional angle, where her mother is alive and her relationship with Clayman is less purely exploitative.
Base Species and Evolution
Kumara is originally a Ninehead, an ultra‑rare multi‑tailed fox monster species.
Her bloodline comes from her mother Quo, a monster comparable to a demon lord seed, making Kumara’s potential extremely high even in childhood.
Her evolutionary path proceeds as follows:
Ninehead (base fox beast form)
Heavenly Star Nine Beast (intermediate evolution)
Divine Fox – upper Holy-Demonic Spirit, Earth Spirit Beast (awakened evolution)
Each evolution boosts her magicule capacity, tail count, and control over tail‑born abilities.
By the time she becomes a Divine Fox, she has complete authority over earth‑gravity, space, and her tail army.
Tail Beasts and the Eight Divisions
Kumara’s core ability is to separate her tails and turn them into independent subordinate monsters.
Originally this manifests as the intrinsic skill Tail Beasts, which later becomes Eight Divisions as she develops it.
She keeps one tail as her “main body” and splits off the remaining eight as separate beings, each with its own mind and specialty.
These eight are collectively called the Eight Divisions and are:
White Ape:
Specializes in staff‑based martial arts and unique body techniques.
Uses wind‑based sorcery, creating vacuum blades and wind barriers.
Moon Rabbit:
Controls ultra‑high‑intensity gravity over wide areas.
Its power fluctuates with the moon’s phases but is terrifyingly strong even at “new moon” levels.
Black Rat:
Spreads lethal plague and disease over large territories.
It is ideal for long‑term attrition and battlefield contamination.
Thunder Tiger:
Cloaks its body in lightning and excels in high‑speed melee assaults.
Because of this, Kumara herself gains extremely high resistance to lightning.
Winged Serpent:
Rules the atmosphere and can freely manipulate oxygen concentration and other air components.
It can suffocate enemies, alter combustion conditions, or disrupt magic based on air.
Sleep Sheep:
Wields illusion and hypnosis powers.
It forces enemies into deep sleep while showing them blissful dreams, making them drop their guard.
Flame Bird:
Manipulates a special flame that burns only enemies, not surrounding trees or structures.
This makes it ideal for precise, battlefield‑safe incineration.
Mirror Hound:
Moves freely between mirror‑like surfaces and can create reflective barriers at will.
The mirrors can reflect magic and other techniques back at attackers.
All eight are essentially extensions of Kumara’s power, not independent “species” she tamed.
They scale with her own growth and become dramatically stronger when Rimuru Tempest calls their names and when Kumara awakens.
Initially, controlling the Tail Beasts is taxing and leads to her power being divided too evenly among them, weakening her central body.
Over time, especially through her studies and training at the labyrinth and the academy, she learns to balance the distribution and command them efficiently.
In the labyrinth, each of the tail beasts becomes an area guardian for floors 81–89.
Kumara herself oversees Floor 90, coordinating them like a commander in a multi‑layered defense system.
Gravity Control and Illusory Beast King (Bahamut)
Kumara specializes in gravity manipulation.
Even before awakening, she can control localized gravity to immobilize enemies or crush them.
Initially, she uses Gravity Control as a standalone ability.
Later, this power is integrated into her ultimate gift Illusory Beast King (Bahamut).
Illusory Beast King (Bahamut) grants her:
Thought Acceleration: Rapid thinking and decision‑making in battle.
Omni‑directional Perception: Enhanced senses that detect threats and information in all directions.
Demon Lord’s Haki: Overwhelming aura that can intimidate or pressure weaker foes into submission.
Gravity Domination: Wide‑range gravity manipulation, strong enough to oppose planetary‑level gravitational forces.
Space Domination: Manipulation of space, allowing teleportation, space barriers, and battlefield control.
Multiple Barriers: Layered magical defenses that shield her and allies against various attacks.
With these combined, Kumara can warp the battlefield, crush enemies with gravity, shield herself with multiple overlapping barriers, and coordinate her tail beasts with near‑perfect information and timing.
Her nine‑tailed form becomes a living fortress and execution ground.
Combat Style and Techniques
Kumara’s preferred combat style is tactical and layered rather than straightforward brute force.
She excels at using her Eight Divisions, gravity, and illusions to outmaneuver and overwhelm opponents rather than trading blows head‑on.
In earlier years, under Clayman, she relied heavily on automatic combat by her tails while she concentrated on gravity manipulation from a safe distance.
This approach made her powerful on paper but left her with relatively little direct combat experience.
After joining the labyrinth, this weakness became apparent.
Colleagues like Apito and Zegion could simply bulldoze through her tricks and force close‑range confrontations where her inexperience showed.
To address this, she underwent intense training.
She sparred repeatedly with her own tail beasts, ran combat simulations, and accumulated real battle experience in the labyrinth’s endless stream of challengers.
Her signature finishing move is Nine-Tail Continuous Slash.
In her full nine‑tailed state, she channels the combined power of all her tails into a flurry of devastating strikes that can slice through even high‑ranking enemies like Kanzus.
In large‑scale battles, she uses:
Gravity to immobilize or compress enemy formations.
Tail beasts to spread disease, illusions, lightning, and control of air.
Mirror Hound to reflect spells and Flame Bird to precisely burn down priority targets.
Later in the story, especially in the web version’s final arcs, she participates in large battles against angels.
By then, she has largely overcome her experience gap and fights confidently as a front‑line guardian.
Strengths and Weaknesses
Strengths:
Kumara’s biggest strengths are her versatility and battlefield control.
She can attack, defend, and control the environment simultaneously via gravity, space control, tail beasts, and multi‑layered barriers.
Her bloodline gives her absurd raw potential, and after her awakening and “name‑boost” trick with the Eight Divisions, her stats rival or surpass some higher‑ranking Twelve Guardian Kings.
Her ability to fight as a one‑woman army makes her ideal for defending labyrinth floors and strategic positions.
Weaknesses:
Her main weakness is and has always been combat experience, especially against simple, overwhelming power.
Opponents like Apito or Zegion who charge straight through her tricks and fight at point‑blank range are difficult for her to handle.
She also has an emotional vulnerability regarding her mother and her destroyed homeland.
Enemies exploiting these emotional scars, as Kanzus did by using Quo’s summoned tails, can temporarily destabilize her.
Nonetheless, by the time of her awakened evolution and angelic wars, Kumara significantly mitigates these weaknesses.
She becomes a seasoned fighter capable of both subtle schemes and direct, overwhelming offense.
Rimuru Tempest
Rimuru Tempest is Kumara’s current master and the one she owes the most to.
He freed her from Clayman’s domination spell, took her into Tempest, gave her a name, and later bestowed upon her the souls needed for awakening.
Kumara’s loyalty to Rimuru Tempest is absolute, but it also carries a strong personal attachment.
She wants to be the one he favors the most and competes, silently or overtly, with others for his attention.
Her habit of reverting to a child form and using cute behavior to ask favors from Rimuru Tempest shows how comfortable she feels around him.
He, in turn, trusts her enough to assign her critical roles like labyrinth floor guardian and one of the Twelve Guardian Kings.
Clayman
Clayman was Kumara’s first master, who bought her from the Eastern Empire.
He exploited her hatred of the Empire, using it to drive her growth, but simultaneously shackled her with Demon Dominate to prevent rebellion.
Under Clayman, Kumara rose to the rank of “Thumb” among his “Five Fingers,” which shows how much he valued her as a tool.
However, the relationship was fundamentally one of dominance and fear rather than trust.
Even though she had the power to seriously injure or even kill Clayman by “exchanging blows,” she could never act on it due to the domination curse.
During her fight with Ranga at Walpurgis, she secretly sent a thought‑message asking for help, desperate to escape Clayman’s control.
After Clayman’s fall, Kumara’s life improved drastically, and he remains a symbol of her dark past.
In alternate stories like Clayman Revenge, the dynamic shifts somewhat, but in the main timeline he is primarily the one who exploited her suffering.
Ranga
Ranga is both the first opponent to overwhelm Kumara in fair combat and one of her saviors.
At Walpurgis, he defeated her completely but understood that she was being controlled and not purely an enemy.
Ranga carried her to Rimuru Tempest, which directly led to the removal of Clayman’s curse.
Afterward, he took care of her in Tempest, and she often rested on his head or by his side, feeling safe there.
He later recommended her as a labyrinth guardian, directly impacting her career path within Tempest.
Kumara regards Ranga as a precious friend and benefactor, someone she feels comfortable around and eager to make proud.
Apito
Apito is a magic insect “Legion Bee” magic user and another labyrinth floor guardian.
Her personality is straightforward, honest, and very battle‑oriented, making her almost the polar opposite of Kumara’s sly, calculating style.
Because of this contrast, they often argue or clash, especially when their methods differ.
Their frequent disputes sometimes give the impression that they can’t stand each other.
In reality, both recognize the other’s strength.
They form a competitive rivalry where each uses the other as a benchmark to improve, and their friction helps sharpen both of them as guardians.
Zegion
Zegion is Apito’s old acquaintance and the strongest member of the Ten Lords of the Labyrinth.
He is widely acknowledged as the pinnacle of labyrinth defenders.
Kumara, despite being the guardian of deep Floor 90, knows she is nowhere near Zegion’s level.
She straightforwardly admits that he is “the strongest” and doesn’t delude herself about surpassing him any time soon.
This clear sense of hierarchy doesn’t bother her; instead, it gives her a model of ultimate power to look up to.
It also frees her from pointless competition with someone in a different league, allowing her to focus on her own growth.
Quo (Mother)
Quo is Kumara’s mother and the former head of the Hidden Monster Village.
She was a fox demon equivalent to a demon lord seed in power but ruled gently, creating a peaceful sanctuary for non‑humans.
Kumara inherits her tail‑division ability from Quo’s bloodline.
Quo herself could divide into multiple powerful tails, and when Kanzus used Plunderer to summon her and her tails, their combined strength nearly overwhelmed Kumara.
The Eastern Empire’s destruction of the village and Kanzus’s murder of Quo became the central trauma of Kumara’s early life.
Her hatred of the Eastern Empire and her burning desire for revenge both stem from this tragedy.
When Kumara finally surpasses her mother’s level and defeats Kanzus with Nine-Tail Continuous Slash, she symbolically steps out of Quo’s shadow.
It is both a personal catharsis and an affirmation that she has grown beyond even her powerful lineage.
In the Clayman Revenge spin‑off, Quo survives due to Clayman’s intervention, changing Kumara’s development and emotional environment.
This alternate continuity shows how much her life is shaped by her mother’s presence or absence.
