Demonic Moons

Name: Kokushibo Age: 485 years old and has the appearance of someone 24 years old Alias: Upper Moon One Species: Demon Male gender Height: 190 centimeters

Kokushibo was a reserved being shrouded in mystery. At the Upper Moons meeting, he was shown to be punctual, respectful of the rules[5] and placed a high value on the hierarchy of the Twelve Demonic Moons[7]. He was also humble, as he did not hesitate to admit failure or complain about any difficulties, rather than acknowledge the strength of his opponent. He has shown a strong sense of loyalty towards Muzan Kibutsuji, and most of his actions were done with the sole purpose of fulfilling Muzan's goals[2].

Despite displaying an outward reserve of character and humility, he was also quite cold: his words could be harsh, especially when reprimanding people. His threats are nothing short of cruel and overwhelmingly serious, and he demands absolute obedience.

He has a complex relationship with his human past. He shows some warmth towards his descendant, Muichiro Tokito, praising his skills and resolve,[2] and is bent on turning Muichiro into a demon in order to save his life. At the same time, he refers to Muichiro and his abilities as the natural result of his "cells" being passed down.[8] As a result, it is unclear whether he has any true attachment to him or if it is a result of disproportionate narcissistic pride. Watching the two demon slayer brothers, Sanemi Shinazugawa and Genya Shinazugawa, makes him nostalgic.[8] Fighting Sanemi made him recall dueling against an ancient Wind Pillar in order to improve his skills.[10]

It is revealed that during his past as a human, he harbored a huge grudge of spite and envy towards his younger twin brother, Yoriichi Tsukiguni, due to the natural talent and abilities he had since birth. These feelings of jealousy and contempt eventually intensified even further upon seeing his brother grow older and having survived said age despite awakening his Demon Slayer Mark that would supposedly condemn him to death at the age of 25.

Kokushibo was a Demon who maintained his human features despite having devoured countless people for 400 years. He maintained a number of rather unusual characteristics: he was a tall man, with a pale skin tone and an athletic and muscular build; his hair was long and black with burgundy edges[6], held by a long ponytail that reached almost to the height of his lower back[5].

On his face, he possessed a series of flame-like markings covering the left side of his head and the right side of his neck; these markings were, in his time as a human, his Hunter's Mark. Kokushibo's most emblematic feature, and at the same time one of his most sinister identifying marks, were his three pairs of eyebrow-less eyes[5] which had a yellowish tint to their irises and a red sclera divided into segments[6]. In the center eyes, his numbering as the Upper Moon One is located, identified with the kanji for First Crescent (壱上弦, Ichi Jōgen?) indicating his dominant position within the Upper Moons.

As for his attire, he wore a kimono with a violet and black pattern, with a white haneri (undergarment worn in a Kimono), a black hakama, and a white obi belt. He possessed a katana made from his own flesh and bones, which was fully decorated with eyes on the cutting blade, the Tsuba, and the Tsuka[7][8]. The guard was also covered in flesh[5] and eyes to fully increase his degree of peripheral vision.

Having been turned into a Demon, Kokushibo went on to develop his breathing style over the next few centuries, creating up to 16 postures by the time he was introduced during the Infinite Dimensional Fortress Arc. It should be noted that it is unlikely that a human could perform such techniques due to Kokushibo's sword being quite long.

Name: Douma Male gender Age: 133 years old but physically 20 years old Species: Demon Height: 187 centimeters Alias: Upper Moon 2

Doma may have appeared to be a friendly and charismatic individual, but far from reality, he was a deadly and calculating being. Believing that he was saving them from their suffering, he happily devoured his followers and other young women. While he might appear to care for his comrades, he felt no genuine sorrow for their deaths.

He was quite nihilistic and lacked human emotion, admitting that even during his human days, the entire concept of emotion was completely foreign to him. Aware that this was abnormal, he made up for his empty "heart" with lies, learning to fake his emotions enough to fool all but the most keen observers.[10] He is shown to be a psychopath, lacking empathy even for his dying parents, complaining about the smell of blood they gave off. In addition to his inability to feel emotions, he has also shown inhuman amounts of pain tolerance, suffering from Congenital Insensitivity.[11]

He has been shown to have several disturbing and unsettling habits, such as sticking his finger into his skull, drilling a hole straight through his temples, and then stroking and manipulating his brain to stimulate his memories of his long life with a completely serene expression on his face.[11] During his interactions with his fellow Upper Moons member Akaza, he showed no negative reactions to her constant fatal physical attacks and making his head explode. In fact, he considered this to be their form of personal "greeting" between two "best friends". Doma even implied that he actually enjoyed these physical abuses as seen when he morbidly asked Muzan Kibutsuji with excitement about what kind of extreme self-harm he should inflict on himself as punishment for his failure[4] and again expressed his delight at Shinobu Kocho for her numerous attempts to poison and kill him.[6]

Despite leading a cult, he was an atheist.

Doma was a Demon who kept some of his human features with slight subtle differences; highlighting his moderate musculature, his pale blue nails which are long and pointed, his pale skin tone, and thick black eyebrows[4].

Her hair could appear silver[5] or pale golden blonde[6]. It was shorter on the left and the rest extended to the right, with several uneven strands spreading out in both directions. Part of her hair fell forward, covering part of her forehead and leaving both her eyes and eyebrows visible. She usually wore her hair loose, with the ends of it hanging down her back in a spiral-like shape[4].

Many have described her eyes as being incredibly rare and beautiful, as in color they appear to be made up of a variety of rainbow pastel shades that fade into each other as they surround her irises; this unusual appearance even causes people to believe in Doma.[7] She is, according to her followers, a blessed being who can communicate with the gods. Like all of the upper moons, she possesses the kanji for both eyes, in her case the Second Crescent (弐上弦, Ni jōgen?)[8] and previously the Sixth Crescent (陸上弦, Roku jōgen?) which credits her as one of the Twelve Demonic Moons.

As for his clothing, he wore a long-sleeved red shirt[4] that was tight to his body, allowing his muscles to be noticeable, while the collar of the shirt was surrounded by a black pattern giving the impression of a dripping stain. He wore beige pants with black lines held up with a gold-toned belt with a silver buckle[6].

On other occasions he was seen wearing a type of jacket similar to a black short-sleeved haori with wide pink edges and patterns in black rectangles and squares. Accompanied by a large black crown with gold designs and black ribbons extending from the ends[9].

Rime — Water Lily Bodhisattva: It is Doma's strongest technique, where he creates a giant ice statue to attack and destroy his opponents, which can also create strong gusts of wind to freeze his opponents and kill them.

Name: Akaza Male gender Height: 185 centimeters Age: 131 years old and physically 18 years old Alias: Upper Moon Three Species: Demon

As a Demon, Akaza retained his human appearance[4] and took the form of a muscular young man with fairly fair skin akin to a bright white tinged with green. Much of his body was decorated with thick blue lines[5], resembling the criminal tattoos he had when he was human[6].

Some of the lines on his face were curved, crossing both his eyebrows and eyes, and extending from below his ears to his temples; another line extended from the center of his hairline to the bridge of his nose. The lines continued to extend around his body: two lines ran around his neck, and three more lines branched down to reach his torso; a central line ran straight down his chest to the middle of his stomach; while the other lines that connected to his neck branched off on either side of his chest to join the other two horizontal lines, this same three-line pattern was also repeated around his waist.[7]

The lines that covered the upper part of his torso extended and then bent straight on each side of his arms, joining with a horizontal line that surrounded the bicep. Below this line, there was another horizontal line and on the sides of this, two straight lines extended that reached the end of Akaza's wrist[8]. On both his hands and feet, it could be seen that all of his fingers were blue and his nails were painted orange[9].

Her eyebrows were thin[10] and black and pink in color.[11] Her eyelashes, as well as her hair, which was short and without bangs, leaving her forehead exposed,[12] were a light pink color.[13] Her eyes had a fragmented blue sclera and her irises were yellow. On her irises she has a number indicative of her position as the third crescent moon within the Twelve Demonic Moons (参上弦 (San jōgen,?))[14].

Akaza was characterized as an impulsive, stubborn, and strong Demon with the idea that he should fight strong opponents and enjoy combat, which is reaffirmed by the pleasure he takes in facing Demon Slayers, especially those who hold the position of a Pillar.[18] He despised anyone he considered weak,[19] but genuinely respected those who were strong in his eyes, regardless of whether they were Human or Demon. Once he met someone he considered strong, he would demand to know their name and would not stop until he found out;[20] he would remember all the names he had committed to memory as a tribute to their strength.

Akaza had a deep-seated psychological need to become stronger, and did not get along with his fellow Upper Moons due to seeing them as rivals. He was especially antagonistic towards the two Upper Moons who held a hierarchical position over him, Doma and Kokushibo, lashing out at Doma and vowing to kill Kokushibo.

Demonic Blood Techniques (血けっ鬼き術じゅつ, Kekkijutsu?) are a series of abilities through which Demons who have consumed enough human flesh to increase their power, make use of their blood for different purposes such as increasing their power, attacking, warping reality and altering the environment around them, among other abilities.

Name: Nakime Female gender Species: Demon Age: 113 years old and physically 23 years old Height: 160 centimeters Alias: Upper Moon Four

Nakime was always characterized by being very silent and calm even in situations where the rest of her classmates usually showed concern[4]. She didn't speak unless necessary or the situation required it; The few times she articulated a word, she tried to keep her responses as short as possible [5].

Before becoming one of the Twelve Demonic Moons, she was an extremely pale woman, with a shade similar to gray. Her hair was dark brown, reaching up to her eyes and falling to her back. Her nails were pointed and very light blue [4].

After becoming the Upper Fourth Moon, her hair stopped covering her eye and it is revealed that she actually has a large pink cyclopean eye with the kanji for "Four", representing her rank [3 ] her.

Her signature outfit consisted of a simple black kimono with white stockings and no sandals. Furthermore, she always carried a biwa with her [4].

Nakime's full capabilities are unknown as she has never been seen in combat, but as the Upper Moon Four, her abilities must be at least superior to those of Kaigaku and Gyutaro. Her great concentration should be noted, as she fought against two Pillars and did not lose her cool at any time.

Demonic Blood Technique (血けっ鬼き術じゅつ, Kekkijutsu?): As a member of the Twelve Demonic Moons, she is capable of using the Demonic Blood Technique and developed an ability that allows her to manipulate the Infinite Dimensional Fortress. It is known that her abilities are related to her biwa. It is not focused on combat, unlike the rest of the Upper Moons, but it is still one of the strongest in terms of utility. With her technique she is able to perform: Fortress Control: Nakime is able to control the entire Infinite Dimensional Fortress by simply blowing her biwa. She is able to create entrances and exits anywhere, as well as being able to move the Fortress to wherever she wants. She can move and create entire rooms and walls. In order to use this ability, Nakime must stand still in one place. Obanai Iguro notes that while it is difficult for Nakime to kill with the ability, she is also very difficult to hit.[6] Automaton Eyes: Nakime's many spying eyes crawl through walls Nakime's automaton eyes.

After receiving blood from Muzan Kibutsuji and becoming the Upper Moon Four, Nakime is able to create eyes that walk on their own. Nakime uses this ability to spy from a long distance and it is the one she used to find Kagaya Ubuyashiki's hideout.

Name: Gyokko Male gender Age: 113 years Height: 150 centimeters in its normal form and 170 centimeters in its full form Alias: Upper Moon Five Species: Demon

Of all the Upper Moons, Gyokko was the one with the fewest human features, being basically a limbless human torso with humanoid features and resembling an armless statue growing in a porcelain vase; similar to a djinn. He wore no clothing and left his torso completely exposed.[5] The design of his vases was usually varied but consisted mainly of floral designs.[6]

She had multiple small, child-like hands that lined her back. Her face was a bit more distorted: she had large mouths with lips[7] painted a leaf-green color[8] and located where her eyes should be, while her real eyes were located vertically one above the other[9] both honey-colored[10]; one eye was present where her mouth should originally be and the other was located in the center of her forehead surrounded by three red dots that were aligned in a triangular shape[11]. On her irises she had a number indicative of her position as the fifth crescent moon within the Twelve Demonic Moons (伍上弦 (Go jōgen,?)). The color of her hair was quite peculiar, having the color tone of a dark violet[12] which she kept combed in the form of thick, separated dreadlocks[13].

When in a dangerous situation, he was able to shed all of the skin on his body to give way to his complete transformation into a demon. His complete appearance was quite similar to that of a merman; he retained his facial features and muscular physique but his body structure became larger and took on a more humanoid form covered in transparent fish-like scales.[14]

Gyokko used to be an arrogant, short-tempered, and superficial individual especially when it came to anything related to his "art". This was shown when Muichiro Tokito easily angered and infuriated him due to him starting to insult and mock the quality of his art; throughout his conversation with the pillar, he constantly praised himself as a "beautiful" being and his work even more so, also showing that he was someone of a narcissist.[15]

He was also shown to be incredibly shallow, petty, and jealous, as seen when he attacked and mutilated Hotaru Haganezuka due to his jealousy towards the latter's focus and dedication to her work, overcoming his own zeal when working on his own art and causing him to want to make the latter lose his focus and waste time at the blacksmith's because of these petty jealousies.

It was incredibly morbid, as when Doma told him to place a human head on top of his flower pots like a plant, Gyokko immediately saw it as further inspiration for his "art".[16] The extent of this morbid and violent inspiration for his conception of "art" is further shown when he brutally murdered several blacksmiths and used their corpses to create a "beautiful" piece by joining their bodies together and gluing several swords to them, this extreme sadism is further shown when he built in the feature of screaming when a sword is pushed deeper into his "artwork", implying that they were still alive.[17]

He can also summon non-deceptive demons, such as fish, from these jars. Gyokko creates a vase-shaped structure made of water that traps his opponent. After that, the enemy will suffocate, and besides being very difficult to cut, this technique makes it harder for a demon slayer to escape, as they cannot use their breathing styles if they cannot breathe. Gyokko creates fish-shaped demon pots from his pots that feed on his enemy's flesh, even if the opponent cuts these fish, they will spread a poisonous liquid before the Nichirin Blade can turn them into powder. The poison is also percutaneous, which can be absorbed through the skin.

Name: Daki Female gender Species: Demon Height: 168 centimeters Age: 113 years old and physically 20 years old Alias: Upper Moon 6 He shares the 6th upper moon spot with his brother Gyutaro

Daki was a tall, pale-skinned woman with prominent veins on her skin resembling fissures on her body. Her hair was white[3] with extensions ending in a lime green gradient[4] at the bottom and was usually styled in a long, full ponytail with kanzashi hairpins (three on each side) holding her hairstyle[3]. On her face was visible a flower in pink tones[4] one on the upper right and another on the lower left[3]. She had large lime green eyes with a number on the irises indicating her position as the sixth crescent moon within the Twelve Demonic Moons (陸上弦 (Roku Jōgen,?) and long eyelashes[3][4].

She wore a rather revealing two-piece kimono consisting of magenta-pink panties tied with long black bows at the sides and with two pieces of magenta fabric covering her bust. She wore thigh-high magenta stockings with black floral motifs and tall three-legged koma-geta/mitsu-ashi shoes.[5]

When she was first introduced as a Warabihime, she appears to fit the characteristics of the oiran style, her hair being the typical date-hyōgo style with numerous Ōgi bira kanzashi decorating and holding it, as well as the use of traditional makeup. She wore a layered kimono with different flower patterns, holding fragments of her Demonic Blood Technique as her obi.[2]

Daki was a very proud and sadistic person, he enjoyed playing with his victims before finishing them off[7]. She seemed to have a somewhat loving relationship with her brother, Gyutaro, but there have been occasions where she has been seen insulting and ridiculing him.[6] He has shown that he had childish tendencies such as throwing tantrums and crying hysterically when things started to go against him or he couldn't get his way.[8] He had a habit of taking out his frustrations on others; such as the time they failed to win against the hunters, lashing out at their older brother in an attempt to vent their frustration over the defeat.[6] As a courtesan, she revealed a seductive side in her typical interactions with her male clientele.[2] During her regular interactions with her brother and fellow courtesans, Daki typically acted like a spoiled and arrogant child.[7] These childish tendencies may be due to the fact that she was only a thirteen-year-old girl when she first became a demon. Gyutaro noted that as a human, she possessed an honest and easily influenced personality, causing her to easily assimilate the personality traits and words of those she trusted and admired,[6][9] as seen when Muzan was shown to be She was easily influenced by Kibutsuji. Her brother believed that the only reason she was the way she is was because he raised her to be selfish and only care about herself because he took her words to "save yourself before others" to heart. ", resulting in his current personality[2].

Blood Demon Art Daki has the ability to manipulate her flesh and transform it into bands of cloth, even being able to transform her body. She also has the ability to create living bands of cloth from her own flesh, which can move independently of Daki and maintain a mental connection with her.

Name: Gyutaro Male gender Species: Demon Height: 180 centimeters Alias: Upper Moon Six Family: Daki younger sister Age: 126 years old and 16 years old physically

Due to the harsh life he lived in extreme poverty bordering on destitution and the harsh tragedies he experienced as a human,[14] Gyutaro described himself as being cruel, mean-spirited, and envious of anyone blessed with a better life than him, leading him to develop a habit of sarcasm, praising a person's best traits and then vengefully trying to kill them, such as he did with Tengen Uzui. Due to these hardships he faced as a human, Gyutaro eventually developed a personal belief that taking something away from those who have a better life than he had as a human is justified. One disturbing habit he seems to have is an inclination to harm himself when he is angry, frustrated, or jealous, as seen when he scratches himself hard enough to tear deep wounds into his own flesh when he becomes jealous of Tengen[15] due to his physical attractiveness as the latter comments on being married to three wives.

Having lived for a century fighting against the Demon Extermination Corps and having killed several Pillars over the years made him someone arrogant, developing the habit of underestimating his opponents and looking down on them as if they were beneath him, as he did with the team of Hunters sent to kill him by having his sister fight and deal with them first instead of doing it himself.

Gyutaro vowing to protect his sister no matter what happens Gyutaro's promise to stand by Daki (Ume in her human days) no matter what happens.

Despite his negative traits, Gyutaro possesses a strong and genuine love for his younger sister, Daki. Having raised her himself due to their mother's mental instability, this familial love was so strong that, despite becoming a demon and nearly forgetting his life as a human, he still retains a considerable attachment to her. Because of this, he has developed a tendency to occasionally spoil her and

As a demon, Gyutaro was a relatively tall young man of somewhat muscular build[4] with a pale grey complexion[5] with black spots whose anatomy was somewhat odd in that his upper torso, arms, and legs were extremely muscular where his waist was incredibly thin, his pelvis jutting out at an unnatural angle[6].

He possessed slender, green-red eyes, their sclera bright orange[7], which were slanted dramatically downwards at the sides and on the irises were numbered indicative of his position as the Sixth Crescent Moon within the Twelve Demonic Moons (陸上弦 (Roku Jōgen,?). He had unruly hair tied back in a ponytail[8], the top portion being jet black while the bottom a brighter green worn[9] into a messy style with uneven bangs and several chokes. His body and face had noticeable markings such as ink-like black stains on his body and a pattern similar to flowing water on his face[10]. Many have considered Gyutaro to be very ugly[11].

He wore no shirt, only a pair of loose blue pants and seven pieces of patterned red cloth to decorate his body, a large one around his neck and three smaller ones around each arm.[12]

Blood Demon Art Gyutaro has the ability to manipulate his blood and transform it into a scythe, which is imbued with a lethal poison. Guytaro can also manipulate his cells to fuse with his sister Daki to sleep inside her, which in turn increases Daki's physical abilities.

Name: Muzan Male gender Age: 1000 years and physically 20 years old Species: Demon Height 190 centimeters

As far as his physical appearance is concerned, Muzan has the appearance of a young man whose age is around 20 years old; he has short hair styled in curls with some strands hanging on his forehead. Like all Demons, Muzan has feline-like eyes, in his case, plum-red in color and his fingernails are pointed and blue in color. When he was a human, Muzan dressed in the Heian Era style using a traditional hitatare, had longer hair reaching down to the small of his back and his eyes were completely devoid of brightness [10].

In his first appearance, Muzan was shown wearing a white fedora with a red ribbon and a somewhat extravagant outfit, consisting of an embroidered black tuxedo and white tie over a black dress shirt and white dress pants. He also wore black loafers. As seen in Rui's memories of meeting Muzan, the Demon King once sported a slightly different hairstyle and outfit in the past. When he first met Rui, Muzan's hair was straighter and parted down the middle. He also wore a baggy tuxedo and a white half-cape over it.

Muzan has the ability to change his physical appearance to disguise himself, appearing either as a black-haired woman dressed in a kimono or a small child. His ability to disguise himself was so perfected that he could even change his presence and confuse his own subordinates.

During the meeting with the Lower Moons, Muzan takes the form of a woman with a bun hairstyle while wearing a long black yukata, causing the rest of the Lower Moons to initially fail to recognize him. [11] Later, he transforms into his latest undercover identity: the sickly adopted son of an elderly couple, taking the form of a small child with pale white skin and silky-smooth, carefully coiffed black hair.

Muzan is callous, ruthless, and exceptionally intelligent. He sees no value in any human he has encountered and shows little value in his own subordinates. Rarely visually upset or happy, he appears completely monotonous and aloof on most occasions, even when callously murdering his own subordinates. The only times he shows emotion is when his vision of perfection advances or when his subordinates completely submit to his will. The manga shows him to be more expressive, particularly when enraged and his facial features are exaggerated to show it as such (possibly as a way to show his normally unreadable emotions). In the anime, his expressions change slightly and his tone of voice tends to be consistent at almost all times, accentuating his detached demeanor.

Muzan shows fear at the idea of ​​dying Muzan, being a human, lived terrified at the idea of ​​dying.

The most prominent trait that Muzan possesses is extreme narcissism, his megalomania and an obsession with becoming the perfect being possessing immortality. This last behavior is derived from his own Thanatophobia having experienced closeness to death literally since his own birth, both in his days as a human and in his later encounter and confrontation with Yorīchi Tsugikuni, the first Demon Slayer to use the Breath of the Sun; an encounter which almost ended with his life and which ended up leaving Muzan with a strong post-traumatic stress disorder causing him to have a violent reaction when he remembers his own near-death experiences.

Being the first Demon, Muzan's powers surpass anything seen before. Muzan is so strong that he was able to withstand a fight with five Pillars and Tanjiro at the same time. So strong is he, that he was able to leave Tanjiro on the brink of death, as well as several Pillars, were it not for the timely intervention of Chachamaru and the antidotes he gave the Pillars and Tanjiro so they could survive the effects of the poison present in their blood. After 30 minutes of combat, Muzan manifested whips from his legs, which increased his attack speed exponentially, to a point where he instantly defeated five exhausted Pillars: Gyomei, Giyu, Sanemi and Obanai, as well as Zenitsu and Inosuke at the same time, while leaving Kanao paralyzed with fear and with her sword broken. [15] It is later revealed that Muzan was growing increasingly slower, due to the effects of the aging medicine provided by Tamayo, which accelerated his age massively. Despite everything, he was able to subdue the pillars that faced him, as well as Tanjiro who was just learning to use Sun's Breath. [16] His strength, speed, endurance, and regeneration capabilities are superior to any conventional Demon and are even considerably superior to those of the 12 Demonic Moons, in addition to his unique number of unique abilities; below is a list of his powers. Unique Body Constitution: Unlike other demons, Muzan possesses a unique body with which he can make use of his complex abilities. Inside him are five brains and seven hearts. If a simultaneous attack hits these vital organs, he will be greatly weakened. [17] In addition to this, Muzan can move his vital organs within his body in order to avoid a fatal blow.

Demonic Blood: It is one of his main abilities; with his blood, Muzan can turn an ordinary human into a Demon who will be under his control thanks to a component present in his blood which when entering the bloodstream of a human, causes their cells to begin to transform, thus making a human become a Demon. The physical changes and powers that the newly created Demon acquires vary depending on the number of people he eats, and can even use a supernatural ability called Demonic Blood Techniques by manipulating his blood for various offensive or defensive purposes. However, if a human receives Muzan's blood in large quantities, their cells will not withstand the physical changes and will self-destruct, causing a horrific death by making the person literally dissolve into their own flesh. Nullifying another Demon's regenerative qualities: As Tamayo explains it, Muzan, being the one who gave rise to all Demons, is the only one capable of killing others of his kind by nullifying the regenerative qualities of their blood and cells, being able to inflict mortal wounds on any Demon who dares to oppose him by destroying their body completely without the need to expose them to sunlight or through the use of Nichirin Weapons. Curse: When Muzan turns a human into a Demon by infusing his blood, he transmits his cells through his bloodstream, thereby ensuring that he shares a bond with the Demon; in this way, he can know its location, read its mind, sense its presence, and if he so desires, destroy its cells. Muzan uses this last to destroy the Demon if for some reason it dares to reveal his identity or if it tries to betray him. However, if a Demon has enough willpower to resist Muzan's control, by refusing to eat human flesh or drink human blood, they can escape the curse. Omnipresence
