Demon Slayer RPG

Zenitsu is a young man of average height, with fair skin, a muscular build, and downward-slanting eyes with a worried expression that fade from soft brown to bright gold. His forked, golden eyebrows fade sharply to a warm orange. He has short, yellow hair of varying lengths, cut straight at the ends where it fades to a darker orange, falling over his face in an uneven fringe, similar to a bowl cut.

Over his standard Hunter uniform, he wears his signature haori, a gradient from yellow to bright orange decorated with a repeated white triangle pattern.

Zenitsu is cowardly, pessimistic, weak-willed, insecure, and anxious, and often claims that he doesn't have much time left to live due to the dangerous job of being a Demon Slayer. He has quite low self-esteem despite his talent and strength, even considering himself useless.

Zenitsu is in a constant state of fear and frequently tries to flee at the sight of danger, claiming he wants to live a modest, normal life instead of that of a Demon Slayer. Because of this, Zenitsu screams and yells a lot, much to the annoyance of those around him. He is also pessimistic at times, especially during the Hashira Training, where he lashed out at Tanjiro and Inosuke for viewing the training positively.

Despite his weaknesses, Zenitsu strives to live up to the expectations others have of him and will give his all when necessary. He has great respect and admiration for his classmates and his late master, Jigoro Kuwajima, and his determination and desire to avenge him help him overcome his cowardice and self-doubt when faced with adversity. Zenitsu also hates himself for his cowardice and incompetence, despite genuinely trying to improve himself.

Zenitsu is also shown to be a notorious womanizer, due to his desire not to be single in case he is killed.

He seems to have a great need for affection and approval from others, traits that stem from his childhood as a lonely orphan who was emotionally exploited by his ex-partners. This desire leads him to flirt with girls he finds attractive and ask them to marry him or care for him, much to their displeasure.

This womanizing nature overrides his otherwise docile and calm personality, particularly when he believes his classmates are flirting with pretty girls; he then erupts into long, hysterical tirades and complaints. Zenitsu is shown to have a strong attraction to Nezuko, openly expressing his affection for her and always rushing to protect her instinctively. During these moments, he also becomes physically aggressive, lashing out at people in frustration.

Despite his outgoing personality, Zenitsu has demonstrated unwavering loyalty to his friends and those who treat him kindly. Throughout the story, Zenitsu remains a faithful companion to Tanjiro and Inosuke; although they argue frequently, Zenitsu cares deeply for Inosuke's well-being.

Inosuke is a young man of average height with a pale complexion and an extremely toned and muscular physique for his age. In stark contrast, he possesses an incredibly handsome and feminine face, which almost made Zenitsu believe he was a girl. He has large, wide-set eyes framed by long eyelashes, with irises ranging from a dark to a soft pale green, black pupils with a small white dot in the center, thin eyebrows, and what could be mistaken for a small, polite mouth. His thick, jet-black hair reaches just below his shoulders, fading to blue at the tips and forming a rebellious, uneven fringe that falls just above his eyes, puffing out before curving and tapering towards his forehead.

Unlike his classmates, Inosuke forgoes wearing a haori, leaving his torso bare. Instead of the usual leg bandages, he opts for knee-high socks made of black bearskin, which serve as a base for the sandals he wears. Notably, his heels and toes are exposed. However, the most distinctive aspect of his appearance is the hollowed-out gray boar's head he uses as a mask, with sky-blue eyes featuring darker blue irises and black pupils, a pink snout, and a pinkish tint on the tops of both ears. Inosuke has modified the boar's head, altering the eyes to allow him to see while wearing it.

Inosuke is hot-tempered, argumentative, brusque, and proud. He always likes to believe he's the strongest fighter in any situation, constantly challenging most people he encounters and wanting others to respect and praise him for his skill. This often leads him into unnecessary danger, as he tends to overestimate his abilities compared to his opponent and refuses to accept defeat.

Immense Strength: As suggested by his highly developed physique and use of Total Concentration Breathing, Inosuke possesses incredible physical strength, being able to wield two katanas instead of one, even swinging them with enough speed to create aerial cuts.

Enhanced Somatosensitivity: Having grown up in the mountains, Inosuke developed an incredibly sensitive and acute sense of touch. His skin can perceive even the subtlest vibrations in the air. Inosuke incorporated this ability into his Spatial Awareness technique, where he uses his keen sense of touch to locate all the demons scattered throughout a giant mountain.

This constant desire to be the best can also make Inosuke very provocative, as he often tries to incite others, most prominently Tanjiro Kamado, to fight him, although in the latter's case he usually fails due to Tanjiro's unconsciously kind nature.

Due to his upbringing among boars, Inosuke has also demonstrated a limited understanding of normal human interaction, at least in his debut, as he often assumes that those who approach him intend to attack him and doesn't seem to grasp the kindness shown to him by others. He is also illiterate and struggles to pronounce people's names correctly, saying Monchiro instead of Tanjiro or Monitsu instead of Zenitsu. Partly due to his lack of understanding of norms and customs, Inosuke can be rude without malicious or seemingly negative intent, and initially treated everyone as enemies.

Enhanced Flexibility: Inosuke is extremely flexible, to the point that he can bend his body backward so far that his head reaches between his feet. He later demonstrates the ability to dislocate his arm to extend his reach and to dislocate any of his body's joints at will.

Immense Speed ​​and Reflexes: Inosuke is an incredibly fast and agile individual, as seen when he was able to dodge Kyogai's numerous aerial slashes as they appeared to the beat of his drums, traverse the Tsuzumi Mansion at inhuman speeds, and manage to evade the Horned Demon's attack at the last moment, taking him by surprise and showcasing his perfected reflexes and speed. In his duel against Tanjiro, he was able to dodge his attacks and quickly counterattack, using both close-quarters combat and his animalistic fighting style to overwhelm him.

Nezuko is a fair-skinned young woman with noticeably large and prominent fangs, a slender build, and sharp nails with a light pink base color that fades to orange-red at the tips. Her hair is long, black, and wavy. It reaches just below her waist, turning a deep orange as it passes her elbows, and appears to be curled into large, straight crests, swept sharply to the left. She has soft-looking pink eyes that appear lighter around the edges of her irises with a Persian pink center; they slant downwards towards the sides of her face and are framed by remarkably long eyelashes.

She wears a light pink, short-sleeved kimono with an asanoha pattern. The lining is a paler pink layered over a flowing white yuban, creating a mid-length, tail-skirted kimono that allows her to move freely, much like a demon. This white garment humbly covers her knees and then extends almost to her ankles, forming an open window. It is secured by a red and white checkered hanhaba obi with an orange-threaded obijime and a green obiage. Over this, she wears a long, dark brown haori that reaches her calves, as well as a pair of zōri with pink straps and white tabi socks, wrapped with thick pieces of black material resembling kyahan. Nezuko also wears a small pink ribbon on the left side of her head to keep her hair out of her face, along with the bamboo muzzle given to her by Giyu Tomioka, which is secured around her jaw with a strip of red cloth.

Nezuko's original personality as a human was that of a kind and caring girl who prioritized others over herself, much like her older brother, Tanjiro. She was also a responsible older sister to her younger siblings and often put their needs before her own.

Tanjiro is a young man of average height with slightly tanned skin and an athletic, muscular build. His hair is messy and black with red tips, combed back to reveal his forehead. His eyes are large and dark red, fading to a burgundy hue with white pupils that appear lighter toward the lower part of the iris, while the upper portion is noticeably darker. He bears a distinctive scar on the upper left side of his forehead. Originally, it was a light pink, patch-like mark, an injury he received after saving one of his brothers from a hot brazier. It remained this way until his battle with the Demon Hand during the Final Selection, after which it became a dark, jagged red scar.

After becoming a Hunter, Tanjiro wears the standard Hunter uniform. Over this, he dons his signature green and black checkered haori. He carries a large wooden box on his back, where his sister sleeps while they travel during the day.

Tanjiro is very kind by nature and has been described by others as having gentle eyes and a compassionate personality. He exhibits great determination and will not give up once he has a goal to achieve; the best example of this is his tireless search for a cure for Nezuko. Although relatively strong on his own, Tanjiro doesn't hesitate to ask others for help when he needs it. He is very protective of his friends, especially his younger sister. However, despite his kind and understanding nature, Tanjiro has a limit to his tolerance and dislikes rudeness and cowardice, as he is easily annoyed by Zenitsu Agatsuma's constant whining and enraged by Inosuke Hashibira's barbaric actions.

Furthermore, she was a responsible older sister to her younger siblings and often put their needs before her own. However, Nezuko wasn't afraid to put herself in danger, protecting her friends from demons even after reverting to her human form. Nezuko's relaxed and human demeanor is further demonstrated by her behavior after Tanjiro apologized to her.

She is still very affectionate and protective of humans, whom she sees as family, though this is mainly due to the influence Sakonji Urokodaki had on her while she slept for two years. Nezuko also retains some of her human emotions, as she has been seen crying when sad and smiling when happy, but overall, she seems more distant than her human companions, though she remains much calmer and less malicious than most demons.

Abnormal Demonic Physiology: Nezuko possesses several unique traits that set her apart from all other demons. In particular, Nezuko can continuously restore her power without consuming human blood, as other demons would have to do. Instead, she regains her strength solely through sleep, though she would have to spend a considerable amount of time sleeping to fully recover and regain her power. Furthermore, Nezuko has an extraordinary growth rate, as demonstrated on several occasions when she becomes stronger without any training or consuming humans.

Combustible Blood: Nezuko's Blood Demon Art allows her to burn her blood into pink flames at will. Activating it required Nezuko to physically bleed from open wounds, inflicted by demon opponents or by herself through self-mutilation. Her flames have a special property that makes them exclusively harmful to demons, demon-owned objects, and Blood Demon Arts, while being completely harmless to humans and other objects.

He has the skills of a demon.

Tanjiro is straightforward and very honest, taking everyone's words with sincerity and seriousness. Upon hearing Tengen Uzui claim to be a god, he asked which area he was the god of. He finds it difficult to lie, and when he does, his face grimaces, as his honesty clashes with the insincerity of his words. Having grown up in rural Japan, Tanjiro has no experience of life in large urban areas. During his missions to Asakusa and Yoshiwara, he gazed in awe at the bright lights enveloping the cities. He naively believed that the Mugen train was perhaps the guardian spirit of the land before being corrected by Zenitsu, and, like Inosuke, he doesn't know what a red-light district is.

Tanjiro's most remarkable attribute is his ability to empathize with anyone, even demons, which initially caused him to hesitate before delivering the final blow. Tanjiro holds a unique ideology regarding demons: he believes that those who have committed evil should be killed without mercy, but that those who repent of their actions should not be scorned after death. This demonstrates great subtlety and maturity in his thinking, likely instilled by his sister.

Hard Skull: Tanjiro possesses an innately strong skull, which the Temple Demon compares to a rock. In certain situations, he can headbutt his opponent with enough force to stun or knock them out completely; in some cases, he can even cause their head to bleed upon impact. His ability to headbutt the Temple Demon twice in a row without being stunned demonstrates that he is capable of doing so more than once. The full power of this attack is shown to give Inosuke a delayed concussion, while Tanjiro suffers no adverse effects.

Enhanced Sense of Smell: Tanjiro possesses an extremely keen sense of smell. Before becoming a Demon Slayer, Tanjiro was known in a village as a child with an exceptionally sharp sense of smell.

It can detect even the most subtle scents and track their location with terrifying accuracy over long distances. It is strong enough to smell the Initial Thread, the slight pause in an enemy's movement that gives them an opening to strike. Its sense of smell is so acute that it can perceive its surroundings through scent alone.

Extrasensory perception: Thanks to his heightened sense of smell, Tanjiro can perceive things beyond the normal range of perception, such as the intentions, feelings, and thoughts of other creatures, including animals like insects and birds. He can also perceive the aura and presence of demons, and even determine their strength level at a glance based on how repulsive and foul their odor is.

Immense Strength: Following his training on Mount Sagiri, Tanjiro has acquired incredible strength in his arms and legs, demonstrating great use of it, from leaping over the gigantic Demon Hand to effortlessly jumping over buildings. Tanjiro also accidentally broke Genya's arm and then shattered Inosuke's ribs, all with a single punch. With his katana, he could wield it with enough force to slice through massive boulders and entire trees. During his training, Tanjiro is capable of doing hundreds of push-ups at once, in addition to a wide variety of other strength-intensive exercises. When not on missions, he frequently trains his body to its limits to reach peak strength and fulfill his duty as a Demon Slayer and his goal of killing Muzan.

Furthermore, a Tsuguko can only inherit the rank if their respective Hashira dies or retires.

The effort required to master any of these methods takes nearly five years of training, though the most talented might achieve it in just two years or so. However, there was one example that was far faster than that: Muichiro Tokito, who managed to rise to the rank of Hashira only two months after joining the Demon Slayer Corps.

The current members of Hashira are:

•Giyuu Tomioka, Water Pillar.

•Sanemi Shinazugawa, Wind Pillar.

•Kyojuro Rengoku, Flame Pillar.

•Shinobu Kocho, Insect Pillar.

•Muichiro Tokito, Pillar of the Mist.

•Gyomei Himejima, Rock Pillar.

•Mitsuri Kanroji, pillar of love.

•Iguro Obanai, Serpent Pillar.

•Uzui Tengen, pillar of sound.

Hashira is the highest rank a Demon Hunter can achieve within the Demon Hunter Corps. Those who hold this position are considered the most powerful and skilled fighters in the entire organization, protecting humanity from threats far more dangerous than other Demon Hunters can handle.

The Hashira, in accordance with their great strength, have the highest authority in the organization, second only to the leader of the Corps, Kagaya Ubuyashiki.

Hashira are assigned a specific region to patrol, usually to gather intelligence on the demons inhabiting that area and to hone their swordsmanship. They are also assigned missions only if lower-ranking members are unable to complete them.

Each Hashira masters a unique breathing style, some of which are even created by the Hashira themselves. Interestingly, swordsmen who use Fire Breathing and Water Breathing have become Hashira in every era, without exception to this day.

To become a member of the Hashira, a Demon Slayer must be among the strongest fighters in the entire Demon Slayer Corps. There are two known (and extremely difficult) methods to prove one's worthiness to become a Hashira: the first is to accumulate a demon kill count of at least 50 as a Kinoe-rank Demon Slayer, or to single-handedly kill a member of the Twelve Demon Moons. Regarding the latter, it is implied that an individual who is the sole survivor of a group effort to kill a member of the Twelve Demon Moons fits the description, as although Sanemi Shinazugawa and Masachika Kumeno killed Lower Moon Uno Ubume together, only the former became a Hashira because the latter perished. The second method is to be a Hashira's Tsuguko (assistant), which requires immense talent.

The Demon Hunter Corps is an organization dedicated to hunting and exterminating demons. Most of its members are fighters, known as Demon Hunters.

Because the Demon Hunter Corps is not officially recognized by the government, its members are forced to work in secrecy, meaning they cannot openly carry their swords in public. Most people are unaware of the existence of demons, and even if they revealed the truth about their work, they would be met with skepticism and disbelief. Allowing Demon Hunters to wield swords openly would only incite chaos and confusion among the general population. By maintaining a low profile and avoiding unnecessary attention, they can carry out their duties covertly and effectively. However, rumors about Demon Hunters have permeated the public consciousness, existing as mere folklore in the minds of some. Yet, when civilians encounter demons or witness a Demon Hunter confronting one, they are confronted with the reality of their existence and the truth behind the stories they have heard.

Without government or other sponsors, the Demon Slayer Corps relies entirely on the resources provided by the Ubuyashiki family for its daily operations. The wealth accumulated by the Ubuyashiki family, acquired through their exceptional foresight, plays a vital role in ensuring that the Demon Slayers have the necessary means and resources to perform their duties effectively.

To become a Demon Slayer, an individual must pass the Final Selection, a rigorous test used as an entrance exam for joining the Demon Slayer Corps. During this selection, candidates must survive for seven days atop Mount Fujikasane, a perilous domain infested with demons. Candidates must rely solely on the skills they have developed through training. Most candidates who participate in the Final Selection have undergone extensive training under the guidance of a Breathing Style instructor. Only when these candidates have reached a satisfactory level of skill and proficiency is their instructor entrusted with participating in the selection.

Candidates who complete the Final Selection receive the standard uniform and the opportunity to choose the ore for their Nichirin Blade, designed to effectively eliminate demons. Each new Demon Slayer is also assigned a rare species of talking bird, known as the Kasugai Crow, for communication.

The members of the Demon Slayer Corps are divided into ten different ranks. From lowest to highest, these ranks are:

Mizunoto → Mizunoe → Kanoto → Kanoe → Tsuchinoto → Tsuchinoe → Hinoto → Hinoe → Kinoto → Kinoe.

Once a Demon Slayer successfully passes the Final Selection and becomes an official member of the Corps, they are initially ranked as Mizunoto, the lowest rank within the organization. By undertaking various missions and demonstrating their skills and dedication, they can rise through the ranks and ultimately reach the highest position in the corporation, known as Kinoe.

The final selection takes place on Mount Fujikasane, where wisteria blooms every season from the base to the slopes. The area surrounding the summit is devoid of wisteria and infested with demons, captured alive and placed on the mountain by existing Demon Hunters. Since wisteria is poisonous to demons, they remain trapped inside the mountain and cannot escape. Most of the captured demons are relatively weak and have only killed two or three people, providing a sufficient challenge for the candidates to test their skills.

At nightfall, the candidates must ascend the stairs leading to the shrine at the mountain's summit and await the start of the event. Nearly twenty young swordsmen typically participate in each iteration. Kiriya Ubuyashiki and Kanata Ubuyashiki, representatives of the Ubuyashiki Family, are the organizers of the event and will arrive together to inform the candidates of the rules. The exam consists of surviving seven consecutive nights on the mountaintop, relying solely on their own resources and without any outside assistance. Candidates who successfully survive all seven nights will have the opportunity to join the prestigious ranks of the Demon Slayer Corps as official Demon Slayers.

After seven days, the exam concludes early the next morning, and the surviving candidates gather once again near the shrine atop the mountain. The organizers from Ubuyashiki congratulate the participants and announce that they will each receive their own Demon Slayer Corps uniform. Measurements are taken to ensure a perfect fit, and their rank is engraved, starting with the initial rank of Mizunoto. The newly inducted Demon Slayers also have the opportunity to select their preferred ore for their Nichirin Blade, which will be forged by skilled swordsmiths and delivered to them two weeks later.

A Demon Slayer wears a highly durable and lightweight uniform that is also water-resistant and fireproof. This uniform is not easily damaged by the claws and fangs of demons, with the exception of the Twelve Demon Moons. They wear their uniforms with a white belt and hakama pants, along with a long-sleeved white collared shirt underneath.

The Demon Slayer uniform is remarkably similar to a Gakuran uniform, consisting of a button-down shirt with a framed white collar bearing the kanji for "Destroy" on the back, a shirt pocket on the upper left chest, and a white undershirt. It also includes long, loose-fitting tattsuke-hakama pants held up by a white belt with a buckle, which can optionally be tucked in with any type of kyahan (sandals) and tabi socks.

The buttons on the Hashira uniform are gold-colored, while lower-ranking Demon Hunters have silver buttons on their uniforms.

Nichirin Blades are special blades that Demon Hunters use and craft specifically to annihilate demons. They are forged from a unique mineral that constantly absorbs sunlight, one of the demons' primary weaknesses. Therefore, decapitation with a Nichirin Blade is one of the few ways a human can kill a demon; the other is using a weapon poisoned with glycine.

Nichirin swords acquire a distinctive color when their owner first draws them, hence they are also known as "color-changing katanas." However, a certain level of skill is required for the wielder, or the blade will not change color.

After passing the entrance exam, each new Hunter is assigned a Kasugai Crow. These crows possess the ability to speak in complete sentences, although their speech is very loud and somewhat limited.

The job of these birds is to deliver missions to their designated demon hunter.

The Kakushi are a brigade responsible for various tasks related to providing support to the Demon Slayers, including:

•Provide first aid to demon hunters on the battlefield.

•Cleaning the battlefield after the battles.

•Guiding wounded and injured Demon Hunters to the Butterfly Mansion for further recovery.

•They act as assistants at the Butterfly Mansion, where they provide help to the mansion's residents and those being healed at the facility.

•Sewing and repairing the uniforms worn by the Demon Hunters.

•Transportation of people to and from Villa de los Herreros.

The number of members in the Kakushi and their recruitment methods are unknown, making them quite mysterious. In some cases, Kakushi members are retired Demon Slayers or those who have been injured or disabled to the point of being unable to fight. There are also individuals who failed the Final Selection Exam but became Kakushi to remain useful to the Demon Slayer Corps.

They wear dark versions of the standard Demon Slayer uniforms, consisting of a modified gakuran jacket and hakama pants. The gakuran jacket has a longer hem and puffed sleeves to allow for freedom of movement, with the kanji for the brigade's name tattooed on the back (隠). Their forearms and shins are covered with black elastic fabric that secures the sleeves and hakama respectively, held in place by a white belt with a buckle. For footwear, they wear plain white jika-tabi with red flat shoes.

To protect their identity, they wear dark head coverings with white linings and a paper-like mask with three dark lines tied around their face, divided into two sections, one in the front and one in the back, which hang freely to allow them to speak and breathe easily.

The swordsmiths are a dedicated group of highly skilled artisans who live and work in the Blacksmiths' Village.

The blacksmiths possess extraordinary skill in forging, repairing, and maintaining weapons known as Nichirin Blades in secluded workshops within the village. These blades are essential tools for the Demon Slayer Corps, as they are the only weapons capable of effectively killing demons. Due to the critical nature of their work, the blacksmiths' workshops and dwellings are guarded with the utmost secrecy, their locations veiled from prying eyes and demonic threats alike. Strict protocols are in place to ensure maximum confidentiality. Demon Slayers wishing to visit the village must travel blindfolded, with their ears and nose plugged, while carrying a Kakushi (a type of protective garment) to prevent information from leaking to the demons. All blacksmiths are also commonly seen wearing variations of hyottoko masks to maintain their concealment, a tactic used to protect them from being tracked.

Swordsmiths dedicate their lives to the craft of sword making, perfecting their skills through years of training and experience. Each swordsmith possesses their own unique style and techniques, passed down from generation to generation or learned from masters of the craft.

To create a Nichirin Blade, blacksmiths carefully select the finest materials, including special minerals with properties that absorb sunlight. They then precisely heat, bend, and temper the metal in a meticulous and sacred process, where the blacksmiths dedicate themselves completely to each sword they create to ensure that Demon Slayers are equipped with formidable weapons. In addition, they also craft a range of combat and training equipment.

Mariposa Estate: Most of the healing at the mansion is done by Shinobu Kocho, though there are also assistants known as Kakushi who run errands and help care for the wounded. In addition, there are other residents who aren't Hunters but offer training programs to facilitate recovery and help injured Hunters heal in optimal condition.

Blacksmith Village: The village is home to the blacksmiths who forge weapons, especially Nichirin Blades, for the members of the Demon Slayer Corps. To protect the village from demon attacks, strict measures are taken to keep the place hidden, and its exact location is kept secret. Demon slayers wishing to visit the village must travel blindfolded, with their noses and ears plugged, while carrying a kakushi to prevent information from leaking to the demons. After a time, travelers are transferred from one kakushi to another. Furthermore, the routes and the kakushi themselves change frequently. Even the kakushi carrying the travelers are unaware of the village's exact location. Guided by Kasugai crows, each kakushi is directed to the next in line, though even these crows are constantly changing.

It's common to see all the villagers wearing variations of hyottoko masks to conceal their identities, a tactic used to protect them from being tracked. Within the village, one can find bustling foundries and workshops dedicated to the meticulous forging and repair of Nichirin blades, the essential weapons of Demon Hunters. Adjacent to these workshops are the residences where the skilled blacksmiths live.

Blacksmith Village: Besides playing a vital role in equipping Demon Hunters, the village also boasts rejuvenating hot springs nestled atop a picturesque hill. The therapeutic waters of these hot springs possess countless healing properties. A long soak in these restorative waters can work wonders, alleviating ailments such as cuts, burns, hemorrhoids, constipation, gout, diabetes, hypertension, anemia, gallstones, and muscle and joint pain. The hot springs are even known to alleviate lesser-known ailments, such as warped personality, rudeness, hay fever, navel itching, and the anguish of a broken heart.

When a Demon Hunter visits the village, it is customary to pay respects to the chief, Tecchin Tecchikawahara, before proceeding with any other activity. To find the chief's house, simply follow the street from the village entrance to the end and then turn left. The chief's residence is located in that direction.

Ubuyashiki Mansion: This was the residence of the Oyakata, leader of the Demon Slayer Corps, and his family. It also served as the Demon Slayer Corps headquarters.

It was located atop a mountain, in a secluded and well-protected area to ensure the safety of its residents and visitors. Its exact location was kept secret to protect against demonic attacks. Compared to the already dark and hidden Village of the Swordsmiths, even more sophisticated methods were employed to conceal the property.

The mansion was of traditional design, with elegant wooden architecture. A wooden deck ran around the perimeter of the house, slightly raised off the ground, serving as a transitional space between the interior and the garden. The mansion's surroundings were serene and peaceful.

Breathing styles are fencing styles that utilize total concentration breathing, which are practiced and taught by demon hunters.

Breathing styles are fencing styles that make use of an esoteric breathing technique known as Total Concentration Breathing, and are practiced and taught by members of the Demon Hunter Corps for use in combat.

All known breathing styles currently taught in the Demon Slayer Corps are derived from Solar Breathing, the first breathing style ever created. Most known breathing styles mimic an element of nature (such as flame, water, and wind) and replicate it with the user's movements, techniques, and abilities. Weapon attacks by Demon Slayers using breathing styles also have greater range, possibly due to the shockwaves or air pressure generated by their weapon when swinging and striking.

New breathing styles are constantly being created to meet the combat needs of a demon hunter, resulting in the use of new weapons in demon hunting (i.e., flails and whips). These breathing styles embody a wider variety of concepts, such as animals, plants, and emotions (i.e., snakes, flowers, and love). In any case, these new creations are always derived from the five fundamental breathing styles. Many are personal creations limited to a single user due to a trait or combat style unique to them, but there are instances where branched breathing styles have found use among demon hunters other than their creators. In both cases, the users are Hashira-level demon hunters or at least highly skilled and proficient.

By using a breathing style, users automatically visualize themselves manipulating the concept behind their style, making it seem as if they are using magic, although those who are less adept and competent in their style will visualize less of it than someone who is.

It's possible to combine different breathing styles when mastering just one proves difficult. Tanjiro Kamado, for example, couldn't fully master Water Breathing like Giyu Tomioka, nor could he withstand the strain of Sun Breathing, so he combined these styles to harness their strengths. This fusion allowed him to deliver more powerful blows and sustain longer battles.

Total concentration breathing is a breathing technique that involves expanding the lungs to take in as much air as possible, accelerating blood flow and heart rate while increasing internal body temperature, which causes the bones and muscles to become more excited.

Using Total Concentration Breathing essentially enhances the user's physical attributes and capabilities without sacrificing their humanity. These attributes include superhuman strength, speed, stamina, durability, and endurance, as well as the mental abilities necessary to keep pace with their superhuman bodies, such as faster thought processes and reaction times. Greater proficiency in Total Concentration Breathing is key to increasing survivability when fighting demons.

•Enhanced Strength: Those who use Total Concentration Breathing gain superhuman physical strength. They can perform powerful feats such as slicing through rocks and trees, generating enormous gusts of wind with a single sword strike, effortlessly breaking an arm, crushing ribs, lifting and throwing another person with one arm, throwing a person tens of meters, and moving enormous rocks with their bare hands.

•Enhanced Speed: Those who use Total Concentration Breathing gain the ability to move and travel at superhuman speeds. They can move with ease faster than the eye can see, giving the impression of teleportation. They can cover great distances instantly and evade extremely fast attacks, such as sound or lightning.

•Enhanced Stamina and Endurance: Those who use Total Concentration Breathing possess superhuman stamina and endurance. They can remain active for extended periods without tiring.

Constant Total Concentration Technique: This is a state of Total Concentration Breathing throughout the morning, noon, and night, and even while sleeping, which advanced Demon Slayers, such as the Hashira, can maintain constantly. There is a huge difference in strength, speed, and stamina between someone who can maintain Total Concentration Breathing at all times and someone who cannot. By practicing it every minute of the day, physical condition improves dramatically.

Learning to maintain a constant state of Total Concentration Breathing requires enormous effort; however, the skill itself is quite elementary despite the effort required. When Tanjiro Kamado first heard about the sustained technique, he thought it impossible, as he already found it extremely difficult to use for even a short time, and when he began practicing it for a longer period, he felt like he was dying. His lungs and head ached, his eardrums throbbed, and for a second he was terrified that his heart would jump out of his ears.

The training process involves blowing into a special type of gourd, much harder than usual. The goal is to blow hard enough to break it. As training progresses, the gourd is replaced with increasingly larger versions of the same type. The largest known specimens are about the size of a chair.

To improve Total Concentration Breathing and blow out the gourd, the user must first work on their lung capacity. Tanjiro did this by getting up early and running, which exercises his lungs with rapid movements. He also practices holding his breath.

Finally, since meditation helps with concentration, he also meditates by sitting in Siddhasana on the roof of the Butterfly Mansion, breathing slowly and deeply, circulating the air all the way to his fingertips. After fifteen days, he could run for longer periods, and his lungs had strengthened. Tanjiro also asked Naho Takada, Kiyo Terauchi, and Sumi Nakahara to hit him with blankets whenever he stopped practicing Total Concentration Breathing while he slept.

After ten more days of training, he managed to maintain the breathing technique for an entire day without stopping and inflated the largest gourd. Furthermore, he matched the speed of the more experienced Kanao Tsuyuri in training.

At a more advanced level, Total Concentration Breathing can also slow the circulation of toxins in the bloodstream and even coagulate serious wounds and injuries. By focusing on every inch of the body and increasing the precision of breathing, sensitivity can be extended throughout the body, allowing for the detection and even healing of hidden internal wounds.

Demon Slayer Marks are irregularities on a Demon Slayer's skin that resemble birthmarks, commonly appearing on their face, chest, or arms. The user's Demon Slayer Mark also seems to be based on their Breathing Style; for example, Giyu Tomioka's Mark takes the form of flowing water, fitting his Water Breathing fighting style. However, this isn't always the case, as Kokushibo's Demon Slayer Mark, as mentioned earlier, resembles fire, which doesn't seem to align with his Moon Breathing.

The Hunter's Mark can only awaken under very specific conditions and grants special abilities, as well as enhancing the bearer's pre-existing traits. Once awakened, the Mark may disappear after a time along with its effects, although it can be reactivated (as seen with Muichiro Tokito and Tanjiro Kamado) by fulfilling the same conditions or through training to maintain the "Marked State" and prevent it from dissipating. A special property of the Mark is its ability to spread from one bearer to another as if they were in resonance.

To awaken the Hunter's Mark, one must survive extremely life-threatening conditions, specifically a heart rate exceeding 200 beats per minute and a body temperature above 39 °C (102.2 °F), conditions that can be fatal in most cases. Muichiro Tokito states that survival is the key difference between those who are marked and those who fail to awaken it. However, perhaps the most important requirement is being in contact with an individual who possesses the Mark or who has been previously marked. Without fulfilling this condition, awakening is not possible.

Awakening the Hunter's Mark comes at a high price. It is said that those who have awakened it die, without exception, before reaching the age of 25.

Enhanced Physical Abilities: Upon awakening the Hunter's Mark, the bearer's physical strength and speed increase exponentially to the point where Hashira or Hashira-level Hunters can overpower and defeat Upper Moons and become comparable to the highest among them. It is implied that the bearer's arm strength increases approximately 100 times after awakening the mark, though this could be an exaggeration, and the actual value could be much lower. The increase in the bearer's speed is also quite noticeable. Their healing rate also increases, as Muichiro Tokito and Mitsuri Kanroji were able to almost fully recover from their respective battles with Gyokko and Hantengu just three days later.

Enhanced Resistance: The Hunter's Mark increases the wearer's resistance to Muzan Kibutsuji's demon-transforming blood, much like Total Concentration Breathing.

Transparent World: Those who possess the Hunter's Mark can access the Transparent World and see within it, allowing them to perceive the bodies of others as if their skin were transparent. This enables them to track blood flow, breathing, muscle contractions, and joint movements of the person they are observing, allowing them to predict their movements and evade their attacks with ease. Furthermore, those who access the Transparent World can perceive the world in slow motion, further enhancing their reaction and movement speed.

The Ubuyashiki family are the founders and current leadership of the Demon Slayer Corps, an organization dedicated to defending humanity from the demonic threat. Thanks to their long history and deep-rooted traditions, the Ubuyashiki family represents authority and knowledge. They are familiar with the numerous demons the Corps faces, as well as the tactics and equipment necessary for battle. They coordinate and supervise the frontline Demon Slayers.

The Ubuyashiki family is a renowned and historic lineage. In the distant past, thousands of years ago, they were related to Muzan Kibutsuji, the progenitor of demons. Because their lineage fathered the first demon, the Ubuyashiki family was cursed, and all males born into the family would be born with a disease that would kill them before they reached adulthood. This disease consists of a burn-like skin condition that will eventually cover their entire body and shorten their lifespan.

Wanting to break the curse, the Ubuyashiki family visited a priest, who told them that the male heirs must marry a woman chosen by a priest. This seemed to work, as the Ubuyashiki sons managed to survive to adulthood, though they still suffered from illness and died in early adulthood. The priest also told them that they must make Muzan's death their life's goal, as the curse would persist until they eliminated the evil and cleansed the stain on their lineage. Therefore, they conceived the idea of ​​establishing the Demon Slayer Corps to vanquish evil and free themselves from the darkness the demons had unleashed. The male members assume the role of Oyakata, serving as the leader of the organization.

Kagaya Ubuyashiki: He was a man of frail build, average height, and very pale complexion. He had shoulder-length black hair, parted in the middle. Due to his family's curse, Kagaya appeared to be rotting alive, with large patches of his skin a sickly pinkish hue and wrinkled, starting on the left side of his forehead and gradually spreading across his body. Furthermore, the curse left him blind, as it affected his eyes, changing the sclera from white to black. While serving as an oyakata, he primarily wore a black yukata, with a white undershirt and a woven brown obi. Over this, he wore a white kimono with a flame pattern emanating from the bottom, dyed with a mixture of light purple and orange.

Kagaya possessed a calm, dedicated, and serene demeanor, showing genuine interest in the members of the Demon Slayer Corps, whom he considered his children. He was also adept at handling criticism and honest about his weaknesses; one of these was his inability to become a Demon Slayer himself, despite being their leader. To compensate for this, he remembered every member of the Corps and visited the deceased at their cemetery daily until his illness prevented him from moving.

Although he may appear lenient, he only gives due consideration to reason and when a situation is free of any bias, as shown when he willingly accepted Tanjiro and Nezuko's situation through a letter from Sakonji Urokodaki, even defending their cause when most of the Hashira respectfully disagreed with his pardon. His manner of speaking, while generally fluent and kind, was extremely discreet and deliberate, using words and intonations in a way that the person he was speaking to would understand.

Soothing voice: Kagaya possessed the ability to calm others with just the tone of his voice and the rhythm of his actions, as he demonstrated with Tanjiro Kamado and even with the angry Hashira.

Extrasensory Perception: Kagaya possesses the ability to perceive the presence of humans and demons, as well as to determine their strength.

Foresight: Kagaya, like the rest of the Ubuyashiki family, possesses great foresight that helps them avoid disastrous situations and has allowed them to amass a great fortune.

Amane was a woman of average height with a pale complexion that contrasted with her red lips. She possessed large, plum-purple eyes (with pink eyeshadow) and short eyebrows, a common trait among her children. Her white hair was loose, styled to the left and right in the front, and in a short ponytail in the back, with two loose strands framing her face. Her beauty was undeniable, as Muichiro Tokito once described her as a forest spirit when they first met, and Mitsuri Kanroji, when invited by Amane to speak, took the opportunity to admire her beauty.

Amane wore a salmon-colored kimono with an orange gradient on the top and floral patterns, and a dark indigo haori with numerous blue butterfly prints. She also wore a brown obi with lighter stripes, secured with an orange obiage.

Amane demonstrated the same calm, strict, and serious disposition as her husband and sons, acting with professionalism and tact when communicating with the Hashira during her time as a substitute when their health began to decline. She proved to be as devoted to the Demon Slayer Corps as her husband and sons, and spared no time in seeking out anything that could be used to tip the scales in their favor.

The Ubuyashiki family has quintuplets, four girls and one boy, destined to be the heir.

Muzan Kibutsuji is the Demon King, the progenitor of all other existing demons and the leader of the Twelve Demon Moons, an organization composed of the twelve most powerful demons under his direct command.

A millennium ago, during the Heian period, Muzan became a demon through an experimental treatment for a terminal illness he had suffered from since birth. His goal ever since has been to live without fear of death and become truly immortal. He plans to achieve this in two ways: by finding the Blue Spider Lily or by creating more demons in the hope that one day, one of them will eventually overcome his weakness for sunlight.

It is later revealed that Muzan is also from the same lineage as the Ubuyashiki family.

Muzan is a tall, slender, and muscular man with an unnaturally pale complexion that could easily be mistaken for illness. He has short, wavy black hair parted in the middle, with two curly, wavy bangs framing his face, and piercing, almond-shaped eyes. His irises are a vibrant red with black, vertical, feline pupils, slits visible around them. He also has sharp, blue fingernails that fade to light blue at the tips. Physically, he appears to be in his mid-twenties.

Muzan wears a white fedora with a dark mahogany ribbon and a somewhat flamboyant outfit, consisting of a black tuxedo embroidered with brown buttons and a white tie over a black dress shirt and trousers. He also wears black loafers.

Muzan is a ruthless, intimidating, cruel, and exceptionally intelligent psychopath. He has no regard for any human he encounters and shows little regard for his own subordinates. He rarely appears visibly upset or happy, and most of the time seems completely dull and distant, even when he is cruelly murdering his own subordinates.

The only times he shows emotion are when his vision of perfection advances or when his subordinates completely submit to his will. Initially, his expressions only changed slightly, showing only a minor shift from his usual calm demeanor, and his tone of voice tended to remain almost constant, accentuating his monotonous behavior. His cruel and imposing nature has earned him both great admiration and fear from many demons.

Muzan's most prominent trait is his extreme narcissism, his pettiness, and his obsession with achieving perfection. Given that he has had over a thousand years to live and observe, with virtually no real challenges, his extreme egocentrism is almost predictable. He is concerned with almost nothing, except overcoming his inability to walk in the sun, which is his primary motivation. His long life and his obsessions have led him to desire that every plan he devises be absolutely perfect, and his superiority complex prevents him from seeing his own failures. His belief in being the closest thing to perfection leads him to have zero tolerance for any failure, brutally punishing those who let him down or whom he considers weak, even if the errors are minor.

Muzan is highly manipulative and cunning, capable of seamlessly integrating into human society, even having his own family. His long life and constant practice have allowed him to assume diverse roles in society and perform them skillfully, including those involving children and women if he so chooses. This life has also granted him great intelligence and the ability to think tactically. His quick thinking and strategic abilities allow him to handle unfavorable situations swiftly and successfully, although this may also be due to the fact that the loss of his subordinates means nothing to him in the long run.

Having lived for over a millennium and gained extensive experience through his telepathic connection with the demons he controls, Muzan is exceptionally intelligent and learned. Possessing five fully functioning brains, this likely enhances his intelligence and other mental abilities, such as memory and cognitive processing. He was able to evade the Demon Slayer Corps for nearly a thousand years despite the keen foresight and intuition of the Corps' leaders, the Ubuyashiki Family, and he has also used demons to create distractions in distant locations when he wants to conceal something from the Corps. Even as a newly transformed demon, he was adept at reading the negative emotions of others and managed to manipulate his five wives into committing suicide.

Due to his apparent superiority and duplicity, he feels no attachment to his henchmen, using and discarding them like disposable pawns as he sees fit. Furthermore, he doesn't allow his subordinates to question him, and regularly applies brutal and merciless punishments if they do. Many of his subordinates, in turn, deeply fear him and carefully measure their words and thoughts for fear of saying anything that might displease him. Despite this, he is able to persuade many demons with promises of power, revenge, and greatness as long as they serve him. His intelligence and manipulation shine through here, as many find the promises appealing, since he encounters many of his subordinates at their lowest points. In the end, all these promises are false, as Muzan only cares about himself and has no qualms about killing his own subordinates to protect his own safety.

Furthermore, his delusional sense of omnipotence is such that he compares himself to natural disasters, something that is far beyond what humans can compare and combat.

The Twelve Demon Moons are a group of the twelve strongest individuals among demons, surpassed in strength and authority only by the Demon King himself, Muzan. Each member of the Twelve Demon Moons has received a large portion of Muzan's blood, greater than that of any other demon, exponentially increasing their power. As proof of this, all members of the Twelve Demon Moons can use Demonic Blood Arts; supernatural powers and techniques that manifest through their blood and to which only demons of considerable power have access.

The Twelve Demon Moons are divided into two groups: the six Upper Moons, numbered one through six, and the six Lower Moons, also numbered one through six. The number represents their rank within the Twelve Moons, determined by each member's strength level, with Upper Moon One being the strongest and Lower Moon Six the weakest. The Lower Moons have their numbers and ranks inscribed on only one eye, while the Upper Moons have their numbers in one eye and the kanji for "Upper Moon" in the other.

Although the exact relationship between the two groups is unclear, it is known that the higher ranks despise the lower ranks. Each of the higher ranks possesses a level of power that far surpasses that of the lower ranks; as proof of their strength, the strongest members of the Demon Slayer Corps, the Hashira, have killed numerous lower ranks over the years, while the higher ranks have killed and devoured many Hashira over the years. Kagaya Ubuyashiki states that it has been over a hundred years since a higher rank was killed following the defeat of Gyutaro and Daki.

Therefore, he believes that Demon Hunters are a group of deviants who cannot accept the "natural" order of things and resume their lives normally while others simply move on after a tragedy. His analogy demonstrates his complete inability to feel compassion or remorse for his actions, given that none of the murders he committed (directly or indirectly) were the result of an accident, but rather acts of pure, carefully orchestrated evil. On the contrary, he considers his greatest adversaries to be the real problems.

Biological Absorption: Muzan has demonstrated the ability to absorb, assimilate, and dissolve organic and inorganic objects. This was first observed when Muzan absorbed the flesh seeds that pierced his skin to nullify their effects. Later, he also accidentally absorbed Tamayo's arm, as well as a drug that transforms demons into humans. This is also seen in his plan to eat and assimilate Nezuko Kamado to gain her immunity to sunlight.

Immunity to decapitation: Muzan is immune to death by decapitation in two ways: instead of his neck, like almost all demons, his weakness lies in his numerous hearts and brains. This protective measure grants him much greater survivability, as he cannot be harmed unless all of his weak points are damaged simultaneously.

Near-absolute regeneration: As the Demon King, Muzan possesses the fastest and most advanced regeneration of all demons, recovering so quickly that it appears as if attacks passed right through him without leaving him injured. He demonstrated his flawless regenerative abilities on numerous occasions. In fact, Muzan has overcome the weakness to decapitation by Nichirin Blades.

Furthermore, Shinobu Kocho has commented that the strength of a high-ranking demon is, at the very least, comparable to that of three Hashira, though it should be noted that the capabilities of a Hashira vary from one to another, especially those who can manifest their Demon Slayer Marks to further increase their strength. While the lower ranks have been replaced countless times, the higher ranks have remained unchanged for the past 100 years, a testament to the strength of their members.

When a member of the group is removed from the Twelve Kizuki, Muzan demotes them by cutting out the number that indicates their rank, leaving an "X"-shaped scar on their finger, signifying their removal from the group. The only known example of this is Kyogai, who had reached his limit and could no longer consume human flesh. This gradually led to Kyogai losing his appetite for humans and his ability to evolve and grow stronger. Therefore, he was deemed too weak to remain in his Lower Rank Six position and was subsequently eliminated.

The Twelve Kizuki have received three tasks to complete on Muzan's orders:

•Find the Blue Spider Lily: (the key ingredient of the experimental medicine that turned Muzan into a demon), but since Muzan's discovery (through Hantengu) that Nezuko Kamado is immune to the sun, he has decided that the first objective of the Upper Ranks is to capture her and bring her to him.

•The destruction of the Demon Slayer Corps: As part of his mission to destroy it, Muzan gave the Twelve Demon Moons specific orders to hunt down and eliminate the Ubuyashiki Family, as they are the leaders and defenders of the corps, and who ultimately keep the Corps alive and allow them to rebuild the organization time and time again, no matter how many times Muzan and the Demon Moons try to destroy it.

Demons are a carnivorous, vampire-like species whose primary diet consists of humans. They are nocturnal, as they are weak in sunlight, though they also remain awake during the day since they do not need to sleep. Demons possess an abnormally powerful physical constitution and potent regenerative abilities, rendering them immune to ordinary weapons and granting them the ability to heal from any wound with ease, even regenerating their heads. Only Nichirin Blades, weapons made of a special ore with sunlight-absorbing properties, can inflict life-threatening injuries. However, even with a Nichirin Blade, the only guaranteed method of killing a demon is through decapitation. Demons are also known to hate wisteria, which is poisonous to them and whose scent they find repulsive.

Virtually all demons possess a murderous instinct to kill and devour humans, and they have lost most of their memories of their human lives. While they still retain their original personalities, they often become darker versions of what they once were, frequently corrupted by their core beliefs and past. However, there are some demons who have fully retained their human emotions and memories, such as Nezuko Kamado, Tamayo, and Yushiro.

Types of Demons (1/5): These demons are identical to normal humans at first glance, and mostly resemble their human forms, only with slight, sometimes imperceptible, alterations in their physiology, which include, among others: paler skin, pointed nails, unique pupils, and specialized markings that resemble birthmarks or tattoos that appear somewhere on their bodies (which may or may not be due to their demonization).

Types of Demons (2/4): These demons have humanoid bodies, but exhibit notable alterations in some aspect of their physiology that make them appear disconcerting or remarkably alarming. Most lesser demons belong to this category, sharing common physical traits such as curved horns, prominent fangs, discolored veins around the forehead, elf-like ears, abnormally colored sclera, and sharp claws.

(3/4): These demons exhibit severe mutations and bear no resemblance to humans. Their appearance is similar to that of traditional beasts, yōkai, and oni. They can exhibit mutations ranging from multiple appendages and disfigured bodies to transformed faces. Some demons are more monstrous and animalistic, while others are more abstract and supernatural.

(4/4): These demons exhibit severe mutations and bear no resemblance to humans. Their appearance is similar to that of traditional beasts, yōkai, and oni. They can exhibit mutations ranging from multiple appendages and disfigured bodies to transformed faces. Some demons are more monstrous and animalistic, while others are more abstract and supernatural.

How They Are Created (1/2): Demons are not born naturally; they are all originally humans who later transformed into demons. The first demon, Muzan, underwent an involuntary transformation when his doctor administered an experimental drug containing the Blue Spider Lily as its main component, in an effort to cure his terminal illness. After becoming a demon, he discovered his enhanced physiology and, while he enjoyed the power it granted him, he also discovered his vulnerability to sunlight, which caused him severe burns upon exposure. Throughout his thousand-year existence, Muzan sought to create more demons, driven by the hope that one of them would undergo a mutation that granted them the ability to withstand sunlight.

How They Are Created (2/2): This quest was not aimed at increasing the total number of demons, but at finding the Chosen Demon that he could absorb in order to grant him the power to overcome his vulnerability to sunlight.

As the progenitor of demons and the source from which almost all of them originate, Muzan is the only being in the world who possesses blood with the unique power to transform humans into demons. His cells permeate all the demons he creates, serving as the foundation of their existence. Consequently, when Muzan is eliminated, all the demons he has spawned will cease to exist.

New demons are created by exposing humans to Muzan's blood, triggering a transformation process, provided the individuals can withstand the resulting mutations. It's important to note that this is not a mystical process, but a biological one, occurring at the cellular level, suggesting that Muzan's blood and the Blue Spider Lily medicine possess mutagenic properties. There are three main methods for achieving demonization:

Muzan's Forced Injection: This method involves Muzan personally injecting a controlled amount of his blood into a human, either through attacks or by taking advantage of an injured person. Contact of the victim's open wound with his blood initiates the transformation. Muzan's attacks can be swift and discreet, such as when he swiftly slit the throat of a passerby on a busy Asakusa street without anyone noticing. Notable examples of successful transformations using this method include Nezuko Kamado, the Demon of Asakusa, Akaza, and Enmu.

Recruitment by Muzan: This method involves Muzan seeking out vulnerable humans he deems worthy of becoming demons and convincing them to willingly accept his invitation. However, he sometimes fails to reveal to his victims that he plans to transform them.

Recruitment for a higher rank: Doma finds Gyutaro and Ume A higher rank turns two children into demons. This method involves the High Rankers of the Twelve Demon Moons providing their blood to humans they deem strong enough to become powerful demons. The blood of these High Rankers alone does not possess the power to transform humans into demons. Instead, it serves as a signal to Muzan that they intend to transform the recruited individual. Once Muzan grants his approval, the blood undergoes a transformation, becoming capable of turning humans into demons. This invitation can only be extended by the High Rankers. The recruited individual who receives the blood must be immensely grateful and is strictly forbidden from spilling even a single drop. Unlike Muzan himself, the High Rankers must find individuals who willingly accept the invitation and cannot force a victim to transform. Notable examples of successful recruits through this method include Daki and Gyutaro, who were recruited by Doma after Gyutaro asked him to save the former, and Kaigaku, who was recruited by Kokushibo after he decided to betray the Demon Slayer Corps to save himself. Throughout his many centuries of existence, Akaza attempted to recruit several Hashira he encountered in battle, including Kyojuro Rengoku and Giyu Tomioka, but each one rejected his offer without exception.
