Tanjiro

As a human, she had a very similar appearance, the only differences being her lack of demon-like traits, fiery-coloured hair, and pale pink eyes. Instead, Nezuko had fully black hair, was tied back in three low buns, was decorated by pink ribbons, and had eyes of a darker pink color, appearing lighter around the lower section of the irises while it appears more darker on the upper part of the irises. She wore the same kimono, just without her haori and with a layered pink kimono with the white yuban underneath, along with a white Onbuhimo cloth tied around her, which she used to carry her little brother, Rokuta Kamado, on her back.

When Nezuko transforms into her awakened form during her fight with Daki, she gains a bigger, taller, and more curvaceous body. As a result, she outgrows her attire, tearing the sleeves of her kimono and the left sleeve of her haori. In addition, she loses her bamboo muzzle and her right footwear. She grows a short white horn on the right side of her forehead, designed with an irregular crack pattern, along with vein-like patterns in her forehead near her horn. She has a vein-like pattern around her left eye. In addtion, she has black cat-like slit pupils, along with crack-like patterns around the rim of her irises. Her most striking new feature is the red and green vine-like pattern that covers her skin, circling around her arms, legs, and chest.

After gaining her immunity from the sunlight and regaining her ability to speak, her appearance mostly stay the same, with the exception of her bamboo muzzle and her eyes now appears to have a black, cat-like pupils with visible cracks-like patterns around her pupils.

Nezuko is a young girl with fair skin, visibly large prominent fangs, a slender build, and sharp stiletto nails with a base color of light pink and ombre transitioning to a red-orange color at the tips. Her hair is long, black, and wavy. It reaches just below her waist, turning a flame-orange color as it passes her elbows, and appears to be crimped into large straight ridges, worn side-swept drastically to her left. She has soft-looking pink pupils that appear a lighter color around the rims of their irises and a persian pink center; they slanted downwards toward the sides of her face and framed by notably long eyelashes. In the manga, Nezuko can sometimes be shown with more than one bow. According to Tanjiro, Nezuko was known as a great beauty in their home town. She wears a light pink, short-sleeve kimono with an asanoha (hemp leaf) pattern, the lining a paler pink layered with the white wavy yuban underneath as a medium-length trailing skirt kimono to freely move as a demon; this, the white clothes lowly cover her knees then goes down to almost her ankles making a open window, secured by a red and white-chequered hanhaba obi with an orange-threaded obijime and a green obiage. Over this, she sports 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 Giyū Tomioka gave her, which is secured around her jaw with a strip of red cloth.

Nezuko Kamado (竈門かまど 禰ね豆ず子こ, Kamado Nezuko?) is the deuteragonist of Demon Slayer: Kimetsu no Yaiba. She is the younger sister of Tanjiro Kamado, one of the two remaining members of the Kamado family, and an informal member of the Demon Slayer Corps. Formerly a human, she was attacked and transformed into a demon by Muzan Kibutsuji.

Tanjiro was born on a mountain as the eldest son of Kie and Tanjuro Kamado, a family of charcoal sellers. After his five younger siblings were born, he adopted the idea that, as the oldest child, he should be strong and endure any hardships for them. Although the family did not enjoy a lavish lifestyle, they lived happily and showed a great deal of love and care for one another. One time, when Takeo accidentally knocked over a hot kettle, Tanjiro jumped in to protect him, resulting in a burn scar on his forehead. Growing up, Tanjiro learned coal-burning techniques and was responsible for selling charcoal in the nearest town in order to earn money for his family. He appeared to frequent the town quite often, as the civilians there easily recognized him and regularly asked for his help. Tanjiro's father was a major influence on him and acted as his teacher for the foundations of the Hinokami Kagura, a ritual dance that was passed down across the family's generations alongside a pair of hanafuda-like earrings, and Tanjiro would often watch him perform this dance. Upon asking Tanjuro about his stamina despite the cold weather, Tanjiro learned from his father that there were specific breathing techniques to continue dancing endlessly. When Tanjiro grew old enough to dance in place of his weakening father, he learned that the correct techniques would allow him to blank his mind, enter a plant-like state, and gain access to the see-through world. Before Tanjuro passed away, a night with the threat of a hungry bear prompted him to show Tanjiro the state in action. Tanjiro was frightened at the sight of the predator, but his father quickly killed it with his axe upon entering the state. Tanjuro's abilities shocked him, and Tanjiro made sure to remember the event. Soon after, Tanjuro passed, and Tanjiro's younger siblings began treating him as their father figure

The handle remains the same, being dark red with black cords, with a black cords wrapped around the middle of the handle completely, and a silver kashira. It is implied to be stronger than the standard Nichirin Katana, as Haganezuka mentioned that the steel was of especially high quality

Standard Nichirin Katana: As a Demon Slayer, Tanjiro carries around a standard-sized and shaped Nichirin katana. When he was training under Sakonji Urokodaki, Tanjiro used a katana with a dull blue blade and a tsuba, which was oval-shaped with four indentations and dull gray in color. Tanjiro also uses this during Final Selection. After the test, he selected an ore, which would then be used to forge his first Nichirin katana by the swordsmith Hotaru Haganezuka. His Nichirin katana is dark gray in color with a obsidian black outline, and the original tsuba is a black ring connected to its core by lines with a border of the same color, which heavily resembles a wagon wheel. The handle is in dark red, wrapped around with black cords, with the middle of the handle is covered with black cords completely, and a silver kashira. Along with his katana, Tanjiro has a standard sheath that is obsidian black in color. Tanjiro damaged or broke his sword a total of three times: the first in his fight with Rui when the latter's thread cut it in half, the second when Akaza punched it into pieces in a fit of rage after impaling him as he fled, and the third during his fight with Daki when he chipped the blade after clashing with the Upper Rank.After the events in the Swordsmith Village, he switched to using the katana he found inside Yoriichi Type Zero that was sharpened and polished by Hotaru Haganezuka. His katana's original tsuba was switched to the one used by the late Kyōjurō Rengoku, which is shaped like a flame, with yellow filling in the middle of the tsuba, a dark red core, and orange border. The new blade was not observed to change color, being already in deep black but having a more intricate, grey pattern with seven jagged, saw-like ridges that are engraved on both sides of the top and bottom of the blade, with the word Slay (滅めつ, Metsu?) engraved on the side

Fake Rainbow (幻げん日にち虹こう, Gen'nichi Kō?) - The user performs high-speed twists and rotations, thus creating afterimages used mostly to evade attacks. The afterimages work most effectively on enemies with good vision.
Flame Dance (炎えん舞ぶ, Enbu?) - A two-combo strike that starts with a vertical slash and then a horizontal one right after.
Thirteenth Form (拾じゅう参さんノ型かた, Jū San no kata?) - The user continuously performs all twelve forms of Sun Breathing in repetitive succession to increase the accuracy and agility of his movements while reducing fatigue. This form was created solely for the purpose of killing Muzan Kibutsuji, since the repetition of all twelve forms aims to destroy Muzan's twelve vital organs (seven hearts and five brains) that move freely inside his body

Dancing Flash (円えん舞ぶ一いっ閃せん, Enbu Issen?)- A modified version of Dance developed and utilized only by Tanjiro. He infuses the Thunderclap and Flash technique of Thunder Breathing into the high-powered slash of Dance by inhaling huge amounts of oxygen, increasing the pumping of blood through his entire body, focusing it on his legs, and releasing it all to assault the target with a slash. This technique was capable of out-speeding Genya Shinazugawa, Nezuko Kamado, and the fleeing Hantengu.
Clear Blue Sky (碧へき羅らの天てん, Heki-ra no Ten?) - The user spins their body horizontally to deliver a 360° slash.
Raging Sun (烈れつ日じつ紅こう鏡きょう, Retsujitsu Kōkyō?) - The user unleashes two horizontal slashes to hit or defend themselves from incoming attacks.
Burning Bones, Summer Sun (灼しゃっ骨こつ炎えん陽よう, Shakkotsu En'yō?) - The user unleashes a large circular slash that defends them from imminent frontal attacks.
Setting Sun Transformation (斜しゃ陽よう転てん身しん, Shayō Tenshin?) - The user backflips into the air to deliver a powerful upended sword slash that aims to decapitate their target.
Solar Heat Haze (飛ひ輪りん陽かげ炎ろう, Hirin Kagerō?) - The user charges towards the target, unleashing a horizontal slash seemingly covered in haze that fails to land, but actually does hit the target.
Beneficent Radiance (輝き輝き恩おん光こう, Kiki Onkō?) - The user spirals into the air and delivers a powerful slash that surrounds the enemy.
Sunflower Thrust (陽よう華か突とつ, Yōkatotsu?) - The user unleashes a single thrust attack with the point of the blade.
Sun Halo Dragon Head Dance (日にち暈うんの龍りゅう・頭かぶり舞まい, Nichiun no Ryū Kaburimai?) - The user unleashes a continuous fast and powerful sword attack that takes the form of a Japanese dragon made of solar flames. This technique is capable of decapitating multiple targets at once.
Fire Wheel (火か車しゃ, Kasha?) - The user leaps behind the opponent and spins in the air downward, releasing a sword attack in a circular motion.

Whirlpool, Flow* (ねじれ渦うず・流りゅう流りゅう, Nejire Uzu - Ryūryū?) - A combination of Third Form: Flowing Dance and Sixth Form: Whirlpool created by Tanjiro. It combines the footwork from Flowing Dance and the twisting movements of Whirlpool, resulting in the swordsman performing an attack around him and conjuring a twisting, swirling, vicious flow of water to redirect projectiles from multiple angles.
Seventh Form: Drop Ripple Thrust (漆しちノ型かた　雫しずく波は紋もん突づき, Shichi no kata: Shizuku Hamon Tsuki?) - The user performs a precise, fast and accurate thrust with their blade, blocking any attacks from any opponent as numerous ripples emerges in front of them.
Drop Ripple Thrust, Curve (雫しずく波は紋もん突づき・曲きょく, Shizuku Hamon Tsuki - Kyoku?) - A modified strike that hits from a specific angle corresponding to the sword's structure, which nearly nullifies the impact and momentum of a moving object.
Eighth Form: Waterfall Basin (捌はちノ型かた　滝たき壼つぼ, Hachi no kata: Takitsubo?) - The user cuts the target vertically in a flowing motion, which is most effective when they are falling downward.
Ninth Form: Splashing Water Flow, Turbulent (玖くノ型かた　水すい流りゅう飛沫しぶき・乱らん, Ku no kata: Suiryū Shibuki - Ran?) - The user changes their footwork in a way that minimizes the landing time and surface needed when landing, allowing them to move without limits. It is ideal when fighting in a place with no solid foothold.
Tenth Form: Constant Flux (拾じゅうノ型かた　生せい生せい流る転てん, Jū no kata: Seisei Ruten?) - The user performs a continuous flowing attack which takes the form of a water dragon that increases in strength and power with each rotation due to momentum.
Dance (円えん舞ぶ, Enbu?) - The user delivers a single high-powered vertical slash

First Form: Water Surface Slash (壱いちノ型かた　水みな面も斬ぎり, Ichi no kata: Minamo Giri?) - The user generates enough momentum to create a powerful single concentrated slash.
Second Form: Water Wheel (弐にノ型かた　水みず車ぐるま, Ni no kata: Mizu Guruma?) - The user leaps and vertically spins forward in the air while releasing a flowing attack in a circular motion.
Second Form: Improved, Lateral Water Wheel (弐にノ型かた・改かい　横よこ水みず車ぐるま, Ni no kata kai: Yoko Mizu Guruma?) - An alternate variation of Second Form: Water Wheel that unleashes a horizontal spin instead of a vertical one.
Third Form: Flowing Dance (参さんノ型かた　流りゅう流りゅう舞まい, San no kata: Ryūryū Mai?) - The user swings and bends their blade in a winding motion along with their body and dances in a flowing pattern, slicing everything in its path.
Fourth Form: Striking Tide (肆しノ型かた　打うち潮しお, Shi no kata: Uchishio?) - The user makes multiple consecutive slashes while twisting their body and sword in a flowing fashion to deliver multiple blows simultaneously.
Striking Tide: Turbulent (打うち潮しお・乱らん, Uchishio - Ran?) - An improved version of the Fourth Form: Striking Tide. Tanjiro increases the quantity of consecutive strikes and slashes along with improving its accuracy in order to contact a specific target during a chaotic situation.
Fifth Form: Blessed Rain After the Drought (伍ごノ型かた　干かん天てんの慈じ雨う, Go no kata: Kanten no Jiu?) - The user changes the grip on their sword and decapitates the opponent in a single flowing strike that causes little to no pain. It is a “sword strike of kindness” used when the enemy willingly surrenders.
Sixth Form: Whirlpool (陸ろくノ型かた　ねじれ渦うず, Roku no kata: Nejire Uzu?) - The user fiercely twists their upper and lower bodies, creating a whirlpool of air that cuts anything caught in it. Its effect and efficiency are enhanced underwater, where they can draw water around their weapon to enhance their slashes

Water Breathing (水みずの呼こ吸きゅう, Mizu no kokyū?): Taught to him by Sakonji Urokodaki, a previous Water Hashira and Water Breathing Cultivator, this was Tanjiro's initial Breathing Style. He became extremely proficient in it, to the point where he had surpassed Sabito, one of Sakonji's best students, and could modify pre-existing forms to suit his circumstances. He also used Water Breathing to take on two members of the Twelve Kizuki, namely Rui and Enmu. However, due to his body not being suited to Water Breathing's techniques, Tanjiro decided to switch to the Hinokami Kagura as his main Breathing Style. Despite this, Tanjiro has not abandoned what he was taught, combining Water Breathing with the Hinokami Kagura, due to the strain Hinokami Kagura placed on his body, in order to have stronger strikes than when he used Water Breathing alone and move for longer periods than if he used Hinokami Kagura alone. He did this to save Hinatsuru from Gyutaro

Hinokami Kagura (ヒノカミ神楽かぐら, Hinokami Kagura?): During his near-death experience in his battle with Rui, Tanjiro awakened this in a memory of his father teaching him this Breathing Style. As his body was more suited to the Hinokami Kagura, he quickly overpowered the Lower Rank demon. However, the sheer force and fatigue it placed on his untrained body caused him to weaken significantly when using it; thus he, only saved it for last-ditch attempts to beat his adversaries. After his battle with Enmu, Tanjiro trained more so that his body could take the strain of its techniques and was capable of using multiple forms in succession in his battle against Daki, although the whiplash from doing so became quickly apparent. Still, through battling Hantengu and undergoing Hashira Training, Tanjiro finally managed to master all the forms in the Hinokami Kagura

Master Swordsman: Tanjiro was shown to be a sword-fighting prodigy, starting out with skill rivaling Sabito, one of Sakonji Urokodaki's strongest students, surpassing him in half a year's time, and avenging his death by defeating the Hand Demon. Despite being Mizunoto-ranked, his skill with the sword was superior to many of his seniors. His improvement in swordsmanship is also exceptional, as shown when he could take on Upper Rank demons months after recovering from injuries and not having experience fighting enemies of that caliber. This is evident as he managed to keep up and defend from Daki's fierce onslaught of sash attacks as well as Gyutaro's attacks, despite the latter being immensely skilled in wielding his pair of Kama and possessing over a century of experience in wielding them. Mitsuri Kanroji commented that accomplishing such a feat was equivalent to 5 to 10 years of harsh training. His initial training in Water Breathing and later utilization of Hinokami Kagura also grant him greater versatility than most Demon Slayers, who typically specialized in one type of Breathing style. With intensive training in the Swordsmith Village, his skills and prowess with the blade could match those of the Hashira, the most powerful sword wielders in the entirety of the Demon Slayer Corps

Enhanced Smell: Tanjiro possesses an extremely sharp sense of smell. Before becoming a Demon Slayer, Tanjiro was known in a village as a boy who had an extremely strong sense of smell. He is able to pick up even the most subtle of scents and track their location with terrifying accuracy over long distances. It is strong enough for him to smell the Opening Thread, the slight pause in an enemy's movement that allows him an opening in which to strike. His sense of smell is so keen that he can perceive his surroundings through scent alone.

Extrasensory Perception: Through his heightened sense of smell, Tanjiro can perceive things outside the normal range of perception, like the intentions, feelings, and thoughts of other creatures, even animals such as insects and birds. He can also sense the aura and presences of demons and even tell their strength level at a glance by how disgusting and rotten their scent is

-Pseudo-Precognition: When training with Yoriichi Type Zero, Tanjiro's sense of smell evolved further to be able to predict up to six moves into the future, being capable of foreseeing the actions and intentions of others merely through scent, even of non-living things like Yoriichi Type Zero itself. Tanjiro noted that the smell of the future was different and much faster compared to the smell of the 'Opening Thread', giving him reflexes and movements comparable to a Hashira and allowing him to go toe to toe with Hantengu's clones early on.

Immense Stamina & Endurance: Tanjiro has incredible stamina and endurance, even before he became a Demon Slayer. This was evident when he had to train in a mountain with oxygen levels lower than those of a thick bog, dodging armed booby traps, running up and down the mountain constantly, and improving his swordsmanship skills and physique all while under these harsh conditions for around two years. His stamina and endurance were further improved having mastered Total Concentration: Constant (全ぜん集しゅう中ちゅう・常じょう中ちゅう, Zen Shūchū Jōchū?), allowing him to stay in the Total Concentration Breathing state 24/7. His stamina increased even further after he mastered the Hinokami Kagura, the same Breathing Style that allowed his sickly father to dance from dusk until dawn in the snow. Through the use of Recovering Breathing, Tanjiro can quickly recover from fatigue and was able to subdue a berserk Nezuko despite crossing his stamina limit and nearly losing his life a few moments prior. Despite having his bottom jaw impaled by Gyutaro's kama, Tanjiro barely showed any signs of pain at all. When training with Kotetsu, Tanjiro was able to endure an extremely intensive training session for seven days non-stop, with no food, no sleep, and barely any water, which he obtained when it was raining, while also getting constantly injured and beaten.

Immense Speed & Reflexes: Tanjiro displays extraordinary speed and reflexes; long before he ever became a Demon Slayer, he managed to dodge an attack from the Water Hashira, Giyuu Tomioka while carrying his enlarged sister, narrowly escaping with only his hair being cut. Even before entering Final Selection, he is shown being able to travel faster than the eye can see and outpace Sabito, an extremely skilled swordsman who was initially able to easily move faster than Tanjiro can process. Furthermore, he can react to the blistering movement speeds of demons even before he starts using Total Concentration Constant (全ぜん集しゅう中ちゅう・常じょう中ちゅう, Zen Shūchū Jōchū?). After a few months of training at the Butterfly Mansion, his speed and reflexes could match those of the strongest members of the Lower Ranks of the Twelve Kizuki. When angered, he was able to move faster than Daki, an Upper Rank demon, could even react. Tanjiro has also shown the ability to casually blitz lower-level demons and ordinary humans. He later was able to blitz three of Hantengu's clones simultaneously and keep up with Akaza, one of the fastest demons in existence. After awakening his Demon Slayer Mark, Tanjiro's speed increases even further, to the point that even Akaza couldn't react in time and process his movements. After awakening his Demon Slayer Mark, Tanjiro gains extremely sharp reflexes, dodging and reacting to attacks

Immense Strength: After his training at Mount Sagiri, Tanjiro has gained incredible arm and leg strength and has demonstrated a great use of it, from jumping over the humongous Hand Demon to leaping over buildings effortlessly. Tanjiro also casually broke Genya's arm and later shattered Inosuke's ribs, all with a single punch. With his katana, he could swing with enough force to slice through gigantic boulders and entire trees. While training, Tanjiro is capable of doing hundreds of push-ups at once, along with a plethora of other intensive strength-related exercises. When not out doing his missions, he frequently trains his body to its uttermost limit in order to attain maximum strength to perform his duties as a Demon Slayer and to fufill his goal of killing Muzan. When he was posing as a courtesan, he was shown to carry dozens of large boxes easily, and when he was angered, he ripped off an Upper Rank's leg. When he was training with Gyomei Himejima, he was tasked with standing beneath a waterfall, lifting three enormous logs on his back and pushing a boulder through town, which he successfully able to achieve

Demon Slayer Mark: Tanjiro’s Demon Slayer Mark takes the form of a blood red flame-like pattern on his top left forehead that replaces his scar, and on to his left temple. After Hashira Training, his scar is replaced with a permanent flame mark, and when he activates his Demon Slayer Mark, it grows in size, reaching past his eyebrows. The flame mark now appears with five jagged, saw-like ridges, with the portion on his left temple is now gone and gain a gap at his hairline on the mark. When unlocking the Transparent World and the Selfless State, Tanjiro’s flame mark would grow and expands even further, reaching past his middle forehead with the gap of his hairline grows even bigger, resembling more like a flames. Interestingly enough, Tanjiro's mark is exactly the same as the marks of Yoriichi Tsugikuni and Kokushibo. The mark drastically enhances all of Tanjiro's natural abilities, such as his strength, speed, and reflexes. Tanjiro awakens his mark for the first time while fighting Upper Rank Six, Gyutaro, which granted him the boost in physical strength needed to behead the Upper Rank, and later awakens it while unleashing the Sun Halo Dragon Head Dance technique against Hantengu's clones. The drawback to his marked state is that Tanjiro can only enter it on rare occasions, and he can only use it for a very short period since it causes exhaustion to his body, as proven in his battles against the Upper Ranks.

Bright Red Nichirin Sword: Tanjiro first unlocked this ability after Nezuko Kamado lit his sword on fire using her pyrokinetic Blood Demon Art, which gave him an edge over Hantengu's clones as every slash that he landed drastically slowed down their regenerative abilities

Transparent World: Like his father, Tanjiro can access the Transparent World while in the marked state, gaining the ability to foresee his opponent's attack by analyzing their blood flow and muscles. In this state, his movement, intuition, and evasion speed increases dramatically. It is also suggested that he accidentally accessed this state during his fight against Daki when Tanjiro perceived her sashes as extremely slow and also found Hantengu's main body in the heart of one of his clones

Selfless State: As he unlocked the Transparent World, Tanjiro also learned the ability to completely erase his presence like his father did, including all of his Fighting Spirit (鬭とう氣き, Tōki?). This technique can also mask one's intent to kill and malice, allowing them to fight undetectable against enemies' that rely on sensing one's intention to fight

Repetitive Action: A technique practiced by a few members of the Demon Slayer Corps, it allows a person to achieve the same effects as Total Concentration Breathing by using repeating pre-set movements or remembering intense feelings to open the five senses and raise their concentration, drawing out the physical powers of the body for a long, extended period. It is possible to use both Repetitive Action and Total Concentration Breathing simultaneously, granting the user immense strength to rival Upper Rank demons. Tanjiro learned this technique after consulting Genya Shinazugawa. He raises his concentration to its maximum limits by remembering the faces of his loved ones and repeatedly recalling Kyōjurō's phrase, "Set your heart ablaze".

Additionally, Mitsuri Kanroji later stated that surviving a battle against an Upper Rank demon equates to around 5 to 10 years of intensive training. Upon receiving intensive training in the Swordsmith Village, Tanjiro's swordsmanship skills were greatly polished and refined while also awakening the ability to "smell the future", giving him movements and reflexes comparable to those of the Hashira. Later, Tanjiro faced Upper Rank Four, Hantengu, and his clones, being able to fend off Urogi while also correctly deducing their abilities. Sekido also noted that Tanjiro undergoes explosive growth in the midst of battle, more apparently during critical moments. After awakening his Demon Slayer Mark for the second time along with the Bright Red Nichirin Sword, Tanjiro was fast enough to blitz three of Hantengu's clones simultaneously. When all four of Hantengu's clones combined to become Zohakuten, Tanjiro, with the help of Genya Shinazugawa and Nezuko, managed to hold their own against him. With the help of a Marked Mitsuri Kanroji, Tanjiro, Genya, and Nezuko managed to chase down the main body and successfully put an end to him, with Tanjiro dealing the final blow. During Hashira Training, Tanjiro underwent gruelling training meant to bolster every member of the organization, targeting many fields such as stamina, flexibility, speed, and swordsmanship. When the final battle against demon-kind began, Tanjiro displayed skills comparable to those of a Hashira, according to Giyu himself. He, along with the Water Hashira, made quick work out of dozens of demons that were designed to have the strength of a Lower Rank Demon

During Rehabilitation Training following his battles in Mount Natagumo, Tanjiro recovered from injuries and trained with Kanao Tsuyuri, an extremely talented Demon Slayer, and the Tsuguko of the Insect Hashira, Shinobu Kocho, eventually enabling him to match her. After mastering Total Concentration: Constant (全ぜん集しゅう中ちゅう・常じょう中ちゅう, Zen Shūchū Jōchū?), which further enhanced his physical abilities, Tanjiro was capable of fighting and beheading Lower Rank One, Enmu, on his own, even managing to come up with a countermeasure to the demon's spells in the midst of battle and possessing enough willpower to commit suicide in his dreams repeatedly in order to follow through with his plan. Later, with the help of Nezuko, Inosuke, Zenitsu, and Kyōjurō Rengoku, Tanjiro decapitates the strongest Lower Rank, despite the demon fusing himself with an entire train and him being under a constant barrage of attacks. With the death of Kyojuro at the hands of Upper Rank Three, Akaza, the Flame Hashira's dying words served as a major incentive for Tanjiro to push on, serving as a major factor in his growth as a Demon Slayer. After the battle, Tanjiro could keep up and fend off attacks from Daki, an Upper Rank demon, a being that has lived for over a century and has eaten seven Hashira during her lifetime - although it was implied she was toying with Tanjiro during their battle. Even after Daki regained full strength in the middle of the battle, an enraged Tanjiro managed to easily overpower her. He came as close as slicing off her neck without her being able to retaliate, although he had run out of stamina and nearly collapsed before he could behead her. While injured, Tanjiro managed to assist a poisoned Tengen Uzui against Gyutaro, the true Upper Rank Six, and later outsmarted and decapitated him while awakening the Demon Slayer Mark momentarily. Thus, Tanjiro became one of the first Demon Slayers to ever kill an Upper Rank, a feat that hasn't been accomplished for the last century

Tanjiro eventually met the Hand Demon, a heavily mutated demon that has eaten 50 humans compared to the average of two to three humans that demons on the mountain consume, making him the most fearsome demon Tanjiro has encountered so far, further proven by the fact that he had killed both Sabito and Makomo. Through his acrobatic skills, swordsmanship prowess, and sense of smell, Tanjiro managed to successfully decapitate the demon. After officially becoming a member of the Demon Slayer Corps, Tanjiro faces numerous more powerful and skilled demons, most of whom utilize Blood Demon Arts. Against the Swamp Demon, Tanjiro and Nezuko managed to subdue the demon and its clones, saving the lives of an innocent woman and bystander in the process. When faced with the likes of Yahaba and Susamaru, more skilled and fearsome demons than before, Tanjiro's tactical intellect and swordsmanship skills allowed him to behead Yahaba on his own while also managing to hold his own against Susamaru. During his mission in the Tsuzumi Mansion, Tanjiro encountered Kyogai, a former member of the Twelve Kizuki, an organization of the twelve strongest demons in existence, and was capable of analyzing and adapting to his unorthodox mansion-shifting Blood Demon Art and defeating him. Despite still being the lowest rank in the organization, Tanjiro could hold his own against demons who shared the powers of an actual member of the Twelve Kizuki, namely the Mother and Father of the Spider Family, and later held his own against the member himself, Rui, who held the position of Lower Rank Five. After recalling the Hinokami Kagura, a Breathing Style he learned from his father as a child, he almost defeated the Lower Rank demon, a feat that many believed only a Hashira, the strongest swordsmen in the entirety of the Demon Slayer Corps, could pull off

From the beginning, Tanjiro was shown to be a prodigious fighter, having a strong natural aptitude for combat, especially swordsmanship. Tanjiro was already introduced to have above-average human abilities, like honed senses, a sharp sense of smell, immense willpower, and great intellect. His naturally obtained abilities go so far as to allow him to outsmart and catch Giyuu Tomioka - one of the most experienced Demon Slayers - off guard and nearly land a blow on him despite being clouded with intense emotions. Moreover, in his first encounter with a demon, Tanjiro managed to slash the neck of the Temple Demon, impressing him. Later, he was able to fend the demon off with a regular hatchet, coming up with unique solutions such as using his durable head to headbutt the Temple Demon and also using his hatchet to pin him down to prevent any movements. While on Mount Sagiri, Tanjiro managed to impress Sakonji Urokodaki, the former Water Hashira, evading dozens of traps hidden all over the mountain to a certain degree of success - ultimately managing to get accepted as a student. When tasked with cutting a giant boulder, Tanjiro met the spirits of Makomo and Sabito, who trained him to properly utilize Total Concentration Breathing and hone his swordsmanship skills. After half a year of extremely intensive training, Tanjiro was able to surpass Sabito in a swordsmanship spar, awakening the ability to see the Opening Thread as well as being able to slice the boulder in two, a boulder bigger and harder than any student before him had cut before. During Final Selection, he was able to easily take down numerous low-level demons while using the Water Breathing Breathing Style without the help of others

Tactical Intellect: In battle, Tanjiro demonstrates high tactical intelligence, being keenly analytical and sagacious; he also shows a natural aptitude and innate intuition in many varied areas. Even against opponents that heavily outmatch him in multiple categories, Tanjiro is capable of creating strategies to beat an opponent on the fly, even if it results in his own death. Upon seeing a fighting style once, Tanjiro can analyze it, and he is capable of accomplishing such a feat even in the midst of a constantly shifting location - where he lacks any environmental advantage. Tanjiro has been noted to be very adaptive against any opponent, having an explosive growth rate. Furthermore, he is very talented at using his opponent's abilities against them. Even if the opponent offers no real details or specifics on their power, Tanjiro can pick up subtle phrases and words used throughout their fights to deduce the ability in a short amount of time. He has conjured new abilities and new Breathing Styles forms, utilizing them effectively upon using them once, and even been able to combine techniques despite not being fully proficient in either of them, such as when he combined Water Breathing and Hinokami Kagura together in order to save Hinatsuru from Gyutaro

Indomitable Will: Tanjiro possesses an undaunted will and spirit, being able to fight and engage in battle against enemies stronger than him with his sheer will alone to kill Demons and protect his sister even when he sustained severe injuries and wounds. The death of his family also played a big role in his insurmountable willpower; his visions of his family members urging him on during times of crisis allowed him to pull through any hardship. During his mission on Mount Natagumo, Tanjiro was willing to sacrifice his life for his sister, relying on nothing but sheer determination to fight through Rui's attacks to kill him. When he was in a battle with Enmu, he displayed his supernatural willpower by committing suicide relentlessly in his dreams in order to awaken from the demon's sleep spell, a feat that even Enmu thought was insane. After Kyōjurō was killed in a battle with Akaza, his final words and actions had a major impact on Tanjiro's mindset and willpower, increasing it to unprecedented levels, as shown when he didn't give up no matter how hopeless a situation was, even in the face of Upper Rank demons

Combat Intuition: This trait of Tanjiro's was pointed out by Giyu during their first encounter, in which Tanjiro laid out a plan to attack Giyu by surprise by charging towards him, not showing the Demon Slayer that he was unarmed, and bringing down Giyu with a hatchet he had thrown in the air beforehand. The attack failed, but Giyu was still quite impressed by Tanjiro's plan, especially considering he was simply an ordinary person at the time. Furthermore, Tanjiro also showed proficiency in hand-to-hand combat despite never practicing martial arts before, allowing him to hold his own and adapt instantly to Inosuke's animalistic, unarmed fighting style

Enhanced Accuracy: Even before he trained to become a Demon Slayer, Tanjiro possessed impeccable aim and precision. This was shown when he outsmarted Giyu and threw his hatchet into the air at a perfect trajectory such that it would strike his head. Later on, as Akaza was escaping into the forest, Tanjiro flung his katana with incredible precision over a long distance until it pierced the Upper Rank's body. Tanjiro also displayed his great precision against Muzan, where Tanjiro was able to aim and throw a barrage of swords at the Demon King with perfect accuracy on two occasions with one functioning eye.

Hard Skull: Tanjiro has an innately strong skull, which the Temple Demon compares to a rock, a trait he inherited from his mother. During certain situations, he can headbutt the opponent hard enough to stun them or knock them out completely; in some situations, he can even cause their head to bleed upon impact. Managing to hit the Temple Demon twice in a row without being stunned shows he is capable of doing it more than once. The full power of this attack is shown to give Inosuke a delayed concussion, while Tanjiro suffered no backlash from it. Tanjiro also head-butted the Wind Hashira, Sanemi Shinazugawa, having temporarily stunned him, leaving the other Hashira impressed by its durability. Tanjiro also used this to temporarily stun Gyutaro, Upper Rank Six, and used the opportunity to gain an upper hand over him. Furthermore, he caused Akaza, Upper Rank Three, to bleed when he headbutted him.

Moreover, his compassion for demons was an abnormality amongst the Demon Slayers Corps as even the most virtuous members viewed them as either mindless beasts or odious villains to be executed without sympathy or regrets. However, as Tanjiro gains experience over his career as a Demon Slayer, he becomes more calculating and strict in his decisions. His courage to protect the weak commits him to face his enemies with respect and dignity, whether they are good people or evil demons. Tanjiro is adamant about serving justice to the evil by any means necessary, even declaring to cut off the heads of demons who have committed heinous crimes and confronting them about their inhumane mindset and their criminal deeds. Something about Tanjiro he hasn’t noticed yet is his tendency to blame himself when things go wrong. This behavior is because of the single significant event, which was the brutal slaughter of the Kamado family, with Tanjiro being the sole survivor. This instills immense guilt and trauma with a feeling he failed to protect them, which causes Tanjiro to have this need to save and protect others. After Tanjuro’s death, Tanjiro took on the role of provider for the family, and this pattern of self-blame continued along with his journey, making him feel responsible for every negative outcome. Tanjiro's extraordinary empathy means he feels the pain, sorrow, and fear of others—even demons—deeply, often internalizing it as if he were personally at fault for their suffering

Upon seeing Daki smirking after witnessing her slaughter innocent people indiscriminately with her sashes, he seethed with rage and confronted her alone. Moreover, Tanjiro became enraged when encountering Akaza, the demon that killed Kyōjurō Rengoku; again, he screamed Akaza's name when he charged to attack and was filled with fury when the demon claimed that he was glad Kyojuro had died. This side of Tanjiro is fully exemplified after Muzan's comparison of himself to a natural disaster while demanding the Demon Slayers cease from seeking further revenge against him; Tanjiro calmly told the demon that he can no longer be allowed to exist any further. In the face of irrational evil, Tanjiro shows a more cold and terrifying side of himself, acting more violently towards his opponents as a result. Tanjiro's most notable attribute is his ability to empathize with anyone, even demons, which initially made him hesitate before delivering the final blow. Tanjiro has a unique ideology regarding demons, believing that those who have committed evil should be killed without mercy, but those who regret their actions should not be belittled after their deaths, showing great nuance and maturity in Tanjiro's thinking, probably brought about by his sister. This is reflected through his frequent prayers for demons killed by him. Tanjiro's compassion was so strong, that he was not above consoling particularly cruel demons defeated by him in their final moments. For instance, he beheaded Mother using a painless Water Breathing form after sensing that she was so filled with despair that she preferred death by his blade. Much later, when Daki and Gyutaro are beheaded and exchanging venomous hatred towards each other, Tanjiro gags the latter and gently tells them to not fight as after all the suffering they caused the demon siblings needed each other for support

Tanjiro is very kind by nature and has been described by others as having very gentle eyes and a compassionate persona. He exhibits a great deal of determination and will not give up once he has a goal to achieve; the best example of this is his relentless quest to find a cure for Nezuko. Even though he is relatively strong on his own, Tanjiro isn't opposed to asking others for help when he needs it. He is very protective of his friends, and especially so of his younger sister. However, despite his kind and understanding nature, Tanjiro does have a limit to his tolerance and has a distaste for rudeness and cowardice, as he easily becomes annoyed by Zenitsu Agatsuma's constant whining and angered by Inosuke Hashibira's barbaric actions. Tanjiro is direct and very honest, taking everyone's words with sincerity and seriousness. Upon hearing Tengen Uzui claim he is a god, he asked what area he was the god of. He has difficulty lying, and doing so causes his face to contort severely as his honest nature clashes with the insincerity of his words. Having grown up in the countryside of Japan, Tanjiro has no experience of life in large urban areas. During his missions to Asakusa and Yoshiwara, he stared in wonder at the bright lights enveloping the cities. He naively believed the Mugen train was perhaps the land's guardian spirit before being corrected by Zenitsu, and, just like Inosuke, he does not know what a red-light district is. Under Tanjiro's rather kind and friendly shell is a person with a growing fire of rage and vengeance inside of them. This side of him leaks out when Tanjiro first confronts Muzan Kibutsuji, ready to take out his sword and attack him. When Muzan escapes, Tanjiro releases his frustration and declares he will be the one to kill Muzan. On Mount Natagumo, when the captured Demon Slayers had their necks snapped by the Mother Spider Demon's threads, Tanjiro showed noticeable anger that even Inosuke sensed

After becoming a Demon Slayer, Tanjiro wears the standard Demon Slayer uniform that is similar to the Japanese military uniforms of the Taishō era. His uniform is black in the manga and tinted a mahogany hue, a reddish-brown color tone, in the anime. It consists of a button-up jacket with a stand-up collar and long sleeves, featuring silver buttons and a shirt pocket on the left breast, with the kanji for Destroy (滅めつ, Metsu?) engraved on the back of the uniform. Beneath the jacket, he wears a white long-sleeved collared undershirt. The uniform also includes tattsuke-hakama pants tucked, fastened with a white belt around his waist, and strapped securely around his calves with a pair of buttoned white kyahan, along with tabi socks that match the color of his uniform. On his feet, he wears a pair of white zōri sandals with dark red straps. Over this, he dons his signature checkered haori. He carries a large wooden box on his back (which was a gift to him from Sakonji Urokodaki), where his sister sleeps as they travel during the day. Throughout his battles, Tanjiro gains multiple prominent scars on his body: he first received a long scar across his left shoulder down to his left chest area, which was caused by an attack by Upper Rank Six Daki's obi. He would later gain seven smaller scars; he has three scars marked across on the same long scar on his left chest area, one scar on his right forearm, two on his left forearm and biceps, and one on the left side of his back, all which were caused by the talons of the manifestation of Upper Rank Four Hantengu's joy, Urogi. In addition, Tanjiro had a scar under his chin caused by being stabbed through the jaw by Gyutaro

Tanjiro is a young man (15) of average height with lightly tanned skin and an athletic, muscular build. His hair is ruffled black that turns to burgundy at the tips, and is swept back to reveal his forehead. His eyes are wide and dark red, fading into a burgundy hue with white pupils that appear lighter toward the lower section of the iris, while the upper portion is markedly darker. He bears a distinct scar on the upper left of his forehead, first seen when his mother took him to watch his father perform the Hinokami Kagura dance. Originally, it was a light pink, patch-like mark — an injury he received after saving one of his siblings from a hot brazier. It remained so until his battle with the Hand Demon during Final Selection, after which it developed into a dark red, jagged mark. Later, during Hashira Training, it transformed once more into a true, permanent flame-like pattern — his Demon Slayer Mark. It is also noted that Tanjiro’s hands are unusually rough for someone his age, a testament to the grueling training he endured under Sakonji Urokodaki. In appearance, Tanjiro closely resembles his ancestor Sumiyoshi, sharing the same facial features, eyes, and hairstyle. He also wears a distinct pair of hanafuda-like earrings with the image of the rising, red sun over a mountain. His hair is also kept tied back in a small ponytail or bun; as he trains with Sabito and Makomo, his hair grows to his shoulders

Tanjiro Kamado (竈門かまど 炭たん治じ郎ろう, Kamado Tanjirō?) is the main protagonist of Demon Slayer: Kimetsu no Yaiba. He is a Demon Slayer in the Demon Slayer Corps who joined to find a remedy to turn his sister, Nezuko Kamado, back into a human and to hunt down and kill demons, and later swore to defeat Muzan Kibutsuji, the Demon King, in order to prevent others from suffering the same fate as him. Before he became a Demon Slayer, Tanjiro was a coal burner before his family was slaughtered by Muzan, while his younger sister, Nezuko, was turned into a demon
