Muichiro Tokito

Muichiro Tokito (時透 無一郎 Tokitō Muichirō?) is a Demon Hunter and the Mist Pillar of the Demon Killing Corps. Muichiro is a young man of short stature, with long black hair finished in mint green, with eyes of the same color. He usually wears the Demon Hunter uniform. Muichiro is an air-headed individual who seems to constantly wander off in thought and never focus on one thing. However, he has been shown to get serious at times and is devoted to his work as a Demon Hunter and the Mist Pillar. Impassive and at times obtuse, Muichiro tends to think only for himself and operates on logic alone. Muichiro's original personality was much more caring and kind having taken after his father. Despite this, he always held an omnipresent rage deeply suppressed inside of him that inevitably drove his training. After his memories returned, Muichiro has been more emotive such as displaying sarcasm and smugness towards the fifth upper moon, Gyokko. Muichiro and his twin older brother, Yuuichiro, were born to a woodcutter and his wife. While they were 10, their mother caught a cold. It eventually turned into bronchitis and killed her while in bed.

Their father, away at the time, went to fetch medicinal herbs during a storm and wound up falling off a cliff to his death. The two siblings survived together. While Muichiro took after the emotive and kind nature of their father, Yuuichiro instead held a cold and impassive outlook. They often bickered and Muichiro considered being with him a living hell. In the following spring, Oyakata's wife Amane arrived to recruit them for the Demon Killing Corps. Muichiro's excitement was opposed by Yuuichiro's unwelcoming and rejecting reception. In an outburst, Yuuichiro revealed that he blamed the death of their parents on their hardworking and selfless nature and adopted a cold outlook hoping to keep himself and his brother alive. While Amane continued to visit the twins, Yuuichiro chased her away each time. In the following summer, a demon arrived at their cabin. Yuuichiro lost his left arm defending Muichiro. As the demon badgered them for their worthlessness, Muichiro lost himself in rage and destroyed the demon with all the tools at their disposal and wooden logs. By sunrise, the demon withered into ash and Muichiro dragged himself back to the house. There, he found Yuuichiro near death praying to the heavens that his brother might survive. He laid there grasping his brother's hand as the latter died and he slowly withered away. Amane and her daughters later arrived to heal him. Afterwards, Muichiro would lose his memories and serve the Demon Killing Corps. He quickly rose to become a pillar while his memories would remain lost until battling in the Swordsmith Village. With his memories gone, he began taking after Yuuichiro's personality.

He met Rengoku during this period in the Demon Killing Corps who told him to do the best they could as pillars. His first blades were made by Tetsuido up until a heart attack that led to his death. Kanamori, following Tetsuido's techniques, created Muichiro's current blade.

Natural Abilities

Enhanced strength: Despite his build being the smallest and seemingly weak of the Demon Hunters and Pillars, Muichiro has been shown to be stronger than Tanjiro by a wide margin and did not budge when the latter held on and gripped his arm with all of his strength despite Tanjiro in the beginning of the series being strong enough to break Genya Shinazugawa's arm.

Omnipresent Rage: Muichiro attributes the origin of his willpower towards training and strength towards the awakened rage within him.

Shinobu Kocho

Shinobu Kocho (胡蝶しのぶ Kochō Shinobu?) was a Demon Hunter and the Insect Pillar of the Demon Killing Corps. Shinobu has short black hair tied back with a purple butterfly ornament and parted fringes. She also has grey compound looking eyes similar to those in bugs. Shinobu is rather short in height and has been described as having a small and weak looking built, which is later reinforced by her saying that she does not possess the physical strength to cut a demon's head off like other the other Pillars. She uses the standard Demon Hunter uniform of a straight-lined black jacket with black hakama pants tucked into a butterfly pattern fabric around her lower legs and white sandals. She also wears a grey haori with a butterfly wing pattern, which fades into a turquoise and pink color on the sleeves. Shinobu is rather laid back, always having a smile on her face regardless of the situation. She seems to enjoy teasing others and can be rather sadistic about it. Despite her relaxed exterior and her initial claim of wanting to get along with demons, she can be rather cruel towards them such as killing the spider older sister after giving her false hope of helping her, and attempting to kill Nezuko without hesitation. Later on she is shown to have a more compassionate side towards both Tanjiro and Nezuko after hearing their full story.

Later during her battle against Doma, Shinobu revealed that she also suffered from an inferiority complex due to her inferior physical abilities compared to her fellow Pillars, having been jealous of them for possessing taller or more muscular bodies than her and cursing her own body for not developing further to make her more effective in combat.it was also revealed that she also held a strong amount of frustration and rage due to everything and everyone she lost that she usually held back. Shinobu was born as the youngest daughter within the Kocho household, living alongside her mother, father and older sister Kanae. She was raised in a loving and caring household until her parents were slaughtered by demons, before her and her sister's eyes. Just when the demon was about to attack her and her sister, they were saved by the pillar, Himejima Gyoumei, who slayed the demon. Determined by the pain and suffering they endured, Shinobu and Kanae both promised to become demon slayers to protect each other as well as prevent other people from enduring the same losses they had to experience. Later in her life, while accompanying her sister Kanae on a trip. The sisters encountered a young girl being led away as a slave on a bridge. Intrigued by her, Kanae took an interest and decided to take the girl back to the Butterfly Estate, against Shinobu's initial wishes. They eventually purchased the girl, named Tsuyuri, from her master and trained her within the Butterfly Estate to become the next tsuguko.

Natural Abilities

Despite not possessing the physical strength to cut of a demons head common to that of a average demon slayer or even the superhuman abilities possessed by her fellow pillars,Shinobu is non the less as dangerous and deadly as the rest of them,She has instead made up for these shortcomings using her extensive knowledge of medicine and poisons and acts as the official head doctor/medical expert of the Demon Slayer corps,having used her skills and knowledge to create a wide array of deadly westeria based poisons incorporated in her thrust/stab swordstyle to make up for her inability to cut of demon heads and using her knowledge to create several antidotes and anti-venoms specifically created to counter the types of poisons/drugs created by demons,as seen when she cured Zenitsu Agatsuma of the poisons that was slowly transforming him into a spider creature.

Sakonji Urokodaki

Sakonji Urokodaki (鱗滝 左近次 Urokodaki Sakonji?) is a Cultivator of Swordsmen in the service of the Demon Killing Corps. He was also formerly a Demon Hunter, having held a position as a Pillar. Urokodaki's face has never been revealed or depicted; he is always seen wearing a tengu mask which covers his face. He appears to be an elderly individual as noted by the countless number of students he's trained as well as his silver coloured hair. He is always seen wearing a jinbei styled kimono with a hood covering his head whenever he is travelling. Having received a letter from Giyu Tomioka requesting that he train Tanjiro Kamado, which also explained the boy and his sister's circumstances, Sakonji set forth from his home to find the two. Upon finding them, he stops Tanjiro from attempting to kill a Demon with his knife, stating that the boy will be unable to kill the creature with such a blunt weapon. Admonishing the youth for his question of how to properly defeat the beast, the elder watches as Tanjiro struggles to come up with a way to dispatch the creature. Sniffing the youth, Sakonji determines that he is no good, as he still has the scent of kindness even when confronted by vile demons. While Tanjiro is still struggling to kill the demon, Sakonji buries the victims of the creature, afterwards kneeling by their graves with his hands together in prayer. He then introduces himself to the youth, asking if he is the one Giyuu spoke of in his letter. Getting an affirmation to his inquiry, Sakonji goes on to ask the boy what he will do if his sister decides to feast on a human, slapping him when he hesitates to answer. He admonishes the youth on his slowness to answer, stating that he lacks determination, and stresses that he must not allow his sister to harm another human under any circumstance. Getting an answer of conviction from Tanjiro, the elder agrees to test the boy to see if he is worthy of becoming a Demon Slayer, telling him to bring his sister and follow him. Sakonji then swiftly makes for his home, with Tanjiro struggling to keep up with his pace. Arriving at their destination, the elder tells the exhausted youth that the test begins now, instructing him to hike up the mountain. He travels with the boy part way up the mountain, telling him that he must make his way back to his home before dawn.

He then vanishes into the heavy fog surrounding them. Later, having made his way back down the mountain, Sakonji drapes a blanket over Nezuko, before noticing a noise at his door. A heavily exhausted and injured Tanjiro opens the door, prompting the elder to recognise his abilities, and thus his passing of the test. Sakonji explains his profession as a Cultivator to Tanjiro, as well as how to join the Demon Killing Corps: surviving the Final Selection. To prepare him for this trial, and to see if he is worthy of even being able to participate in it, Sakonji begins to train Tanjiro in the way of the sword. He explains the intricacies of the weapon and the forces behind it, sparring with Tanjiro to improve his endurance using only his bare hands. Alongside this, he trains the boy in proper breathing techniques, slapping his stomach when he fails to get it right. When Nezuko falls into a coma, Sakonji calls for a doctor, who cannot find anything wrong with her. Finally, after a year has passed, the elder tells Tanjiro that he has nothing more to teach him, instructing him to prove himself by improving the basics he has been taught. He then leads the youth to a huge boulder, telling him that if he can cut it in half, he will be permitted to go to the Final Selection. When Tanjiro hesitates, overcome by doubt, Sakonji leaves without a word, his hand in the boy's training completed. Sakonji compliments Tanjiro on the completion of his training. Much later, after Tanjiro finally succeeds in slicing the boulder in half, Sakonji explains his reasons for not wanting Tanjiro to go to the Final Selection, complimenting the youth on his accomplishment.

He then wraps the youth in a hug, urging him to come back alive from the Demon Killing Corps' test. Before Tanjiro leaves, the elder cuts his hair and gives him a mask to ward off bad luck. Besides, Sakonji explains that Demons increase in power by consuming humans, can use a type of sorcery to alter their bodies and that Tanjiro will be able to figure out how many humans a Demon has consumed if he increases the sensitivity of his nose. When Tanjiro wishes him farewell, asking the old man to look after Sabito and Makomo, Sakonji wonders aloud how the boy knew the names of his two dead apprentices. After Tanjiro returns from the Final Selection, Sakonji and Nezuko embrace him, the elder weeping tears of joy while saying that the youth had finally made it back alive. Fifteen days after this, Haganezuka arrives with Tanjiro's new sword, but ignores the youth's attempts at hospitality, prompting Sakonji to note to himself that the swordsmith hadn't changed. He then agrees with Haganeduka when he notes that Tanjiro's blade may turn red, watching shortly after that as it instead turns black. Noting this, the elder watches as Haganeduka throws a fit over this unexpected development. Sakonji then watches in silence as Tanjiro buttons up his uniform, and subsequently shows him a box made out of "Mist Cloud Fir", which he can hide Nezuko from the sun with. He speculates that Tanjiro's sister may have fallen into her coma because she was attempting to regain strength through sleep, rather than through consuming humans. He goes on to tell Tanjiro that while she was sleeping, he gave Nezuko some suggestions to her subconscious to defend humans as her family from other demons. He also informs his apprentice about Caster Demons and the monster responsible for the creation of other Demons and the murder of Tanjiro's family, Kibutsuji Muzan.

Kyojuro Rengoku

Kyojuro Rengoku (煉獄 杏寿郎 Rengoku Kyōjurō?) was a Demon Hunter and the Flame Pillar of the Demon Killing Corps. Kyojuro was a young adult of tall stature with bright yellow hair with red streaks, black forked eyebrows, and golden eyes. His outfit consisted of the regular Demon Hunter uniform along with a white-yellow gradient pattern and red flame-like ridges at the end. Kyojuro was greatly enthusiastic in regard to his duties as a Pillar and often cheerfully eccentric. He was amiable, kind and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He was an honorable warrior who adhered to his code of morals and principles that was instilled into him by his mother at a young age - the most significant being that those who were born strong have a duty to protect the weak.

Kyojuro is the eldest son of Shinjurou. His father was known as the Flame Pillar of the Demon Killing Corps until his unexpected retirement. During the Demon Train Arc, it is revealed that Kyojuro has a younger brother who trained alongside him until their father ceased to teach them. His strength is displayed when he defends over 200 people from being slaughtered by the demons. He comes face to face with the Third Upper Moon, Akaza, and battles him head on but is fatally wounded and succumbs to his injuries. Kocho Shinobu noted that Tanjiro was on trial, which Kyojuro saw no need for, as the youth's protecting of a Demon was a clear violation of conduct, a matter he stated they could deal with themselves. He then agreed with Himejima Gyoumei's idea to kill Kamado Nezuko, witnessing shortly afterward Tanjiro's coughing fit, and remained silent when Kanroji Mitsuri asked if they should be dealing with their subordinate's trial without Oyakata-sama's input. After Tanjiro headbutted Shinazugawa Sanemi, Kyojuro looked at Mitsuri when she laughed with a neutral expression.

Natural abilities

Enhanced strength: Kyojuro possessed great hand and arm strength that was described as "Unbelievable" by Akaza despite the fact he was gravely injured during that time.

Enhanced speed: Kyojuro could move at high speeds that even a trained Demon Hunter like Tanjiro couldn't see or follow and could even cause tremors with it. 

Giyu Tomioka

Giyu Tomioka (冨岡 義勇 Tomioka Giyū?) is a Demon Hunter and the Water Pillar of the Demon Killing Corps. Giyu is a tall young man with medium length, messy black hair tied back into a low ponytail and dark blue eyes. He wears the standard black Demon Hunters uniform along with a haori with two different patterns, one red and one geometrically patterned with green, orange, and yellow. (the latter belonged to Sabito). Giyu always wears a serious expression on his face and has a reserved personality and a strong sense of justice.

He has no tolerance towards those who don't know their own limitations and throw away their lives. Despite letting Nezuko live due to Tanjiro's persistence, like most Demon Hunters he shows no hesitation when killing other demons, and has no respect towards them. He seems to have a complex with what others think of him and is shocked when Shinobu claims he is hated by many. He doesn't say much and has trouble interacting with others, so he usually keeps himself at a distance. It is revealed that Giyu suffers from an inferiority complex which he developed since his participation in the Final Selection. It gets severe to the point where he contemplates abandoning his position as the Water PIllar until Tanjiro helps him realize that instead of acting on his survivor's guilt, he should cherish his life and live on for the people who sacrificed their lives for him.

When Giyu was young, his family was killed by demons. Giyu survived as he was protected by his elder sister. When Giyu was 13 years old, he met Sabito and they were great friends due to their similar pasts and age. They both entered the Final Selection in the Wisteria Flower Mountain. However, Giyu was injured due to a demon attacking him. Luckily, Sabito saved him before heading off towards another cry for help. It appeared that Giyu fainted and after the week was over, he was accepted. As for Sabito, he was the only one who died during that selection.

Swordsmanship

Breath of Water Style (水の呼吸 Mizu no kokyū?)[22]: Taught by Sakonji Urokodaki. The user can increase the amount of oxygen in one's blood by controlling his breathing pattern. This increases his strength and agility to equal a demon's. Giyu has learned to do full focus breaths at all times as all pillars, further increasing his base strength, speed, and stamina. While he knows all of the Breath Style techniques, he has developed one additional by himself.

Muzan Kibutsuji

Muzan Kibutsuji (鬼舞辻無惨 Kibutsuji Muzan?) is a Demon, the first of his kind, and the progenitor of most other Demons. He is also the enemy of the Kamado family. He is the one that killed the Kamado family, turned Nezuko Kamado into a demon and made Tanjiro Kamado an orphan. He looks like a man in his late twenties. He has curly black hair and somewhat small eyes, his pupils are vertical like cat eyes and colored plum red. He usually is shown with a white fedora with red ribbon and a somewhat extravagant outfit. Muzan has the ability to change his appearance as shown in the manga. During his meeting with the Lower Moon's, he arrived disguised as a woman wearing a yukata and was not recognized by the demons. He also once disguised as little bookworm child in hiding. Muzan is a cold-hearted and ruthless individual with a narcissistic streak and an obsession for perfection. He wants every plan he concocted to be absolutely perfect, which is why he doesn't tolerate failures of any kind, resorting to punishing those who fail him or those he considers weak. His inflated ego is such that he doesn't take kindly to being mocked, demonstrated by killing a pair of drunk men simply for being rude to him along with their woman partner, all in gruesome fashion while proclaiming his superiority of being close to that of perfection.

By proxy, he also dislikes when he is questioned or ordered by those beneath him, and doesn't take his opponents seriously. He has shown to be fairly manipulative and cunning, being able to blend in human society normally, even having a family of his own to add. His intelligence makes him a quick-thinker who is able to deal with unfavorable situations rapidly. Because of his perceived superiority and his double-faced nature, he feels little attachment to his henchmen, using them and discarding them as disposable pawn whenever he pleases. He is able to sway many demons to his side with promises of power and grandeur, which are ultimately false given Kibutsuji only cares about himself, and has no qualms about killing his own men to protect his own safety. As proof of this, he curses his subordinates in a terrifying manner so that none of them may utter his name, or else they will be killed instantly in a morbidly cruel manner. Interestingly this almost paranoic sense of self-preservation, contrasts with his megalomania. Muzan was diagnosed with a disease that would kill him before he reached the age of 20. He sought medical assistance from Blue Spider Lily, but he turned into a demon as a result. In a fit of rage, he killed the doctor. Since the sun was fatal to him, he resorted to doing his activities only during the night. At some point in time, Muzan almost got himself killed by the Breath of the Sun user, although he managed to escape and survive. Ever since then, he was more vigilant and careful about encountering possible Breath of the Sun users, who can be identified by a pair of Hanafuda earrings they usually wear.

Powers and Abilities:

Regeneration: Muzan is probably the fastest in term of regeneration. Even having his body destroyed and his head completely destroyed wouldn't kill him

Extrasensory Perception: Muzan can feel demons' and humans' presences, as well as bloodlust.

Absorption: He was going to absorb Tamayo, and planned to absorb spikes that penetrated his flesh, as well as planning to eat Nezuko to obtain her immunity to the sun, Adapted to become immune to being beheaded by blades created with sunlight imbued metal.

Inosuke Hashibira

Inosuke Hashibira (嘴平伊之助 Hashibira Inosuke?) is a Kanoe ranked Demon Slayer and member of the Demon Killing Corps and a traveling companion of Tanjirou Kamado. Inosuke is usually seen wearing a grey boar mask, with a shirtless version of the Demon hunter uniform. Without the mask, he has messy shoulder-length black hair that fades to a blue color, and large green eyes with long eyelashes. He is described as having a girly looking face which significantly contrasts with his muscular body. Inosuke is extraordinarily short-tempered and proud and makes a big deal out of fighting opponents stronger than him claiming that's his only hobby. Inosuke will not think about the difference in power between him and his opponent; this often led him to be in danger. He is a sore loser and is always trying to compete with Tanjiro and provoke him into fighting with him and usually failing.

Due to growing up in the mountains by himself Inosuke has trouble interacting with others and only cares about himself most of the time. However, as time goes by, Inosuke becomes more influenced by Tanjiro, and he also starts to think and to use strategies before going head-on with an opponent. Inosuke was raised by boars for most of his life before the Final Selection; it was revealed later that he was born into a family with an abusive father and caring mother. Eventually, Inosuke's mother, Kotoha, and he fled from their family. Afterwards, Inosuke—who was still an infant at the time—and his mother were taken in by Doma into his Eternal Paradise cult. Kotoha loved to sing to Inosuke but would apparently change the song lyrics each time. However, after finding out that Doma eats his worshippers, Kotoha fled with her son. Running aimlessly for a human village, Kotoha eventually ended up at the top of a cliff. Seeing no escape route, Kotoha makes a last ditch effort to save Inosuke by dropping him into the river below the cliff. It was after this that Inosuke was taken in by boars and his mother was devoured by Doma.

Zenitsu has short blond hair, which was originally black, and brown eyes with thick eyebrows. He wears the standard Demon Hunter uniform underneath a white-triangle pattern, yellow haori. Zenitsu is a coward, always claiming he doesn't have long to live due to the dangerous job of being a Demon Hunter. He is also a bit of a womanizer and likes to hit on girls who he thinks are cute and ask them to marry him much to their annoyance. Zenitsu has low self-esteem but still wants to live up to the expectations others set up for him.

However, he was constantly afraid and would always cry and run away. He claims he wants to live a modest life where he can be useful to someone. Despite all his spinelessness, Zenitsu holds great respect and admiration towards his comrades and his deceased teacher, Jigoro Kuwajima. His focus and drive in avenging him wash away all his cowardice and second thoughts. When Zenitsu was a young boy, he was financially supported by a woman who owned a lot of debt. She had eloped with Zenitsu, which got him into troubled and it was 'Gramps', the former Thunder Pillar, who saved him from the trouble. Gramps decided to train Zenitsu along with his eldest disciple, Kaigaku. On one of the days during his training, Zenitsu climbed up a tree because he felt that he was disappointing Gramps, when suddenly, a stroke of lightning hit him, causing his hair to turn blonde. Zenitsu and Kaigaku hated each other; however, Zenitsu respected Kaigaku and treasured him. Zenitsu eventually wished to fight alongside Kaigaku one day, and thus he created a seventh style, 'Breath of Thunder, Flaming Thunder God'.

Natural Abilities

Enhanced Sense of Hearing: Zenitsu has a heightened sense of hearing, allowing him to detect danger from even the faintest of sounds. He could also hear the inner thoughts of people if he uses the sense of hearing to its fullest ability.

Unconscious Combat: Zenitsu becomes stronger when he sleeps. When his life is in danger, the fear he experiences exceeds his limits making him fall unconscious. When Zenitsu is asleep, he can perform his swordsmanship at a high level purely based on instinct alone. However, as he continues to improve his skills and courage, he begins to depend on this ability less and less.

Breath of Thunder Style (雷の呼吸 Kaminari no kokyū?): Taught to Zenitsu by a former Pillar, Jigoro Kuwajima. This technique increases the user's strength and agility to equal a demon's. There are a total of six styles that can be used with the Breath of Thunder, but Zenitsu was so untalented that he was only able to learn the first of the six styles, which is said to be the simplest. Later on, he was able to create a seventh style when confronting his former senior.

Nezuko Kamado

Nezuko Kamado (竈門禰豆子 Kamado Nezuko?) is Tanjiro's younger sister. She was turned into a Demon by Muzan Kibutsuji. She is one of the main protagonists of Demon Slayer: Kimetsu no Yaiba. Nezuko has long black hair which she tied into a bun as a human but wears loose as a demon. It is decorated with several small, light pink ribbons. As a demon, her black hair fades to orange near the bottom. Her eyes are bright pink but were formerly a deep red as a human. She carries a piece of bamboo in her mouth, which is bound by a red tie. She wears a pink kimono with a star pattern, a red and white checkered obi, and a black haori. On her feet and legs, she wears pink zori sandals, white socks, and black leg wraps. She was known to be a great beauty in her home village. As a demon, she can change the size of her body. She has also gained sharp fangs, claw-like nails, and slit pupils as a result of becoming a demon.

Nezuko's original personality as a human was that of a kind and caring girl, who thought of others before herself much like her older brother Tanjiro. She was a responsible elder sister to her younger siblings. As a demon, Nezuko seems to have forgotten a good portion of her memories as a human, besides those related to her family. She is still very caring and protective towards other humans who she sees as members of her family due to Urokodaki's influence while she was asleep for two years. She is also rather brazen, and does not seem to fear fighting; she fiercely guards her brother as well as her allies. She still retains her human emotions, as she has been seen to cry and be happy, but in general she appears more detached than her human cohorts, as well as calmer and less malicious than most demons. As a demon, Nezuko does not talk often and stutters a lot. This may be due to her bamboo mouthpiece, which is seldom removed. It also means she is sometimes hard to read. Nezuko grew up on a mountain alongside her older brother, Tanjiro, and the rest of her siblings and mother. She is the eldest daughter of the Kamado family. She presumably took care of her younger siblings as an assistant to her mother, as is briefly witnessed prior to her family's death. Unlike Tanjiro, who was responsible for selling firewood in town, Nezuko would usually help out around the family home. Tanjiro and Nezuko as babies. The family was somewhat poor and as a result, Nezuko sometimes had to go without things like new clothes in order to ensure that the rest of her siblings had enough food to eat. She did not appear to view this as a burden, and instead was content to help her family. After a demon killed her family aside from Tanjiro, Nezuko was turned into a demon as a result of the attack. At first, she was rather wild and even attacked her single remaining brother. However, she quickly came to her senses and defended him from Giyu. Since then, she has traveled with her brother in order to find a way to become human once again.

Demon Abilities

Ability to Change Body Size: Ever since Nezuko was turned into a Demon, she can change the size of her body at will. She usually turns smaller to fit herself inside basket / box, and turns Larger to battling Demons.

Enhanced Strength: Nezuko can fight and defend herself from Demon attacks, and she occasionally uses her legs to kick open doors. Her kicking power depends of her body size, and her kicks also able to sever Demons head with ease.

Regeneration: Nezuko possesses a tremendous regeneration ability that able to restore severed limbs within seconds. The true nature of this ability is solidifying her blood from her severed body parts that she could manipulate at will.
Rage Empowerment:

When Nezuko is under the dire situation, she could transform into a berserk-like state, with vines tattoos circling her body, her veins popping out and a single horn protruding from her right forehead side. This form enhances Nezuko fighting ability, at the cost of her becoming more demon-like, including the need to feed on humans blood. So far, the only way she could revert back to normal is to have someone (in her case, Tanjiro) sing her a lullaby. During the demon slayers fight against Hantengu, Nezuko manages to control this form at will.

Sunlight Resistance: For some reason, Nezuko obtained a body which did not burn under sunlight, unlike other demons. However, this resistance isn't perfect as she still prefers to avoid sunlight, given the way she hides from it and has Tanjiro carry her around during the day.

Tanjiro Kamado

Tanjiro Kamado (竈門炭治郎 Kamado Tanjirō?) is the main protagonist of the manga and anime, Demon Slayer: Kimetsu no Yaiba. He is a Kanoe ranked Demon Slayer and a member of the Demon Killing Corps. He is hunting down the Demon who is responsible for the murder of his family and his sister's transformation into one. Tanjiro has burgundy hair combed back and dark eyes with a scar on the top left of his forehead. He wears long rectangular earrings with a sun symbol and a checkered black and green patterned haori over the standard Demon Hunter uniform. He carries around a wooden box where his sister sleeps during the day.

Tanjiro is kind by nature and has been described by others as having very gentle eyes. He has a great deal of determination and will not give up once he has a goal to achieve; an example is finding a cure for Nezuko. Even though he is relatively strong on his own, he isn't opposed to asking others for help when he needs it. He is very protective of his friends and even more so of his younger sister. His most important attribute is his ability to empathize with anyone, even demons. This often makes him hesitate when killing demons. However, this trait also could make some Demons to redeem themselves moments before death, albeit rarely. For the years of his service and amount of experience he faced, he became more calculating and strict in his decision. His courage to protect the weak committed him to face his enemy with respect and dignity whether good or evil demons. Tanjiro grew up on a mountain alongside his younger sister, Nezuko, the rest of his siblings, and his mother.  He is the eldest son of the Kamado family. He was very loving towards his brothers and sisters and would go out of his way to care for them, and was admired for it. He was responsible for things like selling firewood in the nearest town in order to earn money for the family. After a demon killed his family aside from Nezuko, he realized that Nezuko had become a demon. After being confronted by and proving his resolve to Giyu Tomioka, Tanjirou was guided towards the goal of becoming a demon slayer. Since then, he has traveled with his sister in order to find a way to turn her human again.

Natural Abilities

Enhanced Sense of Smell: Tanjiro has a heightened sense of smell even before he underwent sword training. It is strong enough for him to smell the 'line of interval'-- the slight pause in an enemy's movement-- and distinguish between species, as well as their approximate position. After training, he can smell emotions as well as track objects, humans and demons over long distances.

Fighting ability: This trait of Tanjiro's was pointed out by Giyuu Tomioka during their first encounter in which Tanjiro skillfully laid out a plan to attack Giyu by surprise by charging towards him not showing he was unarmed and plan to have brought down Giyu with an axe he had thrown in the air beforehand.

Enhanced strength: After training, Tanjiro gained immense strength and speed and has demonstrated a great use of it (i.e., Jumping over twice his height during the Final Selection arc when fighting the Demon who killed Urokodaki Sakonji's disciples. His forehead is sturdy as well, although this ultimately become one of the running gags in the series.
