The Hashira

Appearance: Giyu is a fairly tall young man of a lean muscular stature and pale complexion, who is almost always seen wearing a serious and emotionless expression. He has unruly black hair of uneven lengths that sticks up in tufts around his head, which he wears tied back in a low messy ponytail at the base of his neck. His bangs fall over his eyes in an uneven fringe. His eyes are sharp and moderately large, their irises a deep sapphire that fades to a lighter blue and their pupils a bluish-black, and are framed by thin eyebrows.

Giyu wears a dark cyan-tinted version of the standard Demon Slayer uniform with buttoned white leg-wrapped kyahan and a pair of white zōri with dark blue straps and tabi socks underneath being the same cyan color as his uniform. Over this, Giyu wears a haori that's split down the middle into two different patterns: the right one a solid dark red, and the left one geometrically patterned with rhombi of green, orange, and yellow. These haori were later noted to have belonged to his late older sister, Tsutako Tomioka, and his deceased friend Sabito.[6]

Giyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice with no tolerance towards those who don't know their own limitations and throw away their lives.[9] Despite letting Nezuko Kamado live due to Tanjiro Kamado's persistence, he shows zero hesitation when killing other demons and has no respect or mercy towards them like most Demon Slayers.[10] Even so, Giyu violated the Demon Slayer Corps' code of conduct without hesitation to protect Nezuko during Shinobu's attempt to kill her. This implies that he doesn't completely despise demons as some other Hashira do, and is willing to make an exception for a demon by letting them live if they don't kill and eat humans. This shows that he is more pragmatic in dealing with demons rather letting his hatred cloud his judgement.

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?)[28] - 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?)[29] - The user leaps and vertically spins forward in the air while releasing a flowing attack in a circular motion. 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?)[30] - 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.

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?)[32] - 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?)[33] - The user fiercely twists their upper and lower body, creating a whirlpool of air that cuts anything caught in it. Its effect and efficiently is enhanced underwater, where the user can draw water around their weapon to enhance their slashes.

Eleventh Form: Dead Calm (拾じゅう壱いちノ型かた　凪なぎ, Jū Ichi no kata: Nagi?)[38] - A form of his own personal creation, the user ceases all body movements and enters a state of complete tranquility, deflecting, blocking and cutting any incoming attacks with imperceptible speed with his blade. However, its effectiveness is limited as fast and numerous attacks can break through.

Appearance: Mitsuri is a curvaceous young woman of deceptively muscular build and a pale skin complexion. She stands slightly taller than average. She has large round, pale green eyes with long eyelashes and a small beauty mark beneath each of them. She has long, light pink hair that fades into a lime green color at the halfway point, which she wears in three thick braids. She has five shorter, choppy clumps hanging over her face as voluminous bangs, the tips lime green as well. When she was trying to get married, her hair was dyed black in an attempt to make herself look more "normal."

Mitsuri wears a heavily modified dark plum colored version of the standard Demon Slayer uniform along with a plain white haori that was gifted to her by Kyojuro Rengoku.[6] Because of its tight fit, the chest area of her jacket and her undershirt is left unbuttoned, and she wears a short pleated mini skirt in place of the usual tattsuke-hakama pants. Additionally, she wears a pair of navy blue thigh-high socks layered with the vertically striped lime-green socks Obanai Iguro gave to her and a pair of white zōri with pink straps tied and fastened with a bow on the front.

Mitsuri is a very emotional, passionate, and jovial individual who constantly compliments and swoons over her comrades in her head, likely a contributing factor towards her nickname as "the Hashira of Love." Although she can be shy and is easily flustered, Mitsuri is always kind to others. However, despite her gentle and seemingly innocent demeanor, Mitsuri will show no mercy in the face of demons, instead expressing such sentiments with a fierce tone. She showcases a great amount of dedication to the Demon Slayers' cause. Despite being put out of commission by Muzan at an early stage in their battle, she was determined enough to return and fight.

Given her desperation for marriage, Mitsuri decided to become a member of the Corps with the purpose of finding a suitable husband stronger than her, a rather difficult task given the astounding level of her physical strength. Upon joining the Corps, she felt an immense amount of guilt for her reasoning behind becoming a Demon Slayer to the point where she ate much less than her typical meals. However, she was able to move past those feelings with the help of Shinobu Kocho and Obanai Iguro.[9] Besides her rather emotional personality, Mitsuri can also come off as somewhat childlike at times. When she is asked to explain the process of obtaining the Demon Slayer Mark, she describes it using bizarre onomatopoeia. She's also prone to exaggerated over-reactions. She is a very caring person, always showing others her love as befits her Hashira title.

First Form: Shivers of First Love (壱いちノ型かた　初はつ恋こいのわななき, Ichi no kata: Hatsukoi no Wananaki?)[25] - The user dashes forward and performs a single slash that winds through the target, hitting multiple areas with one slice. Second Form: Love Pangs (弐にノ型かた　懊おう悩のう巡めぐる恋こい, Ni no kata: Ōnō Meguru Koi?)[26] - The user performs a singular, long-winding swing that cuts the target at multiple angles. Third Form: Catlove Shower (参さんノ型かた　恋こい猫ねこしぐれ, San no kata: Koi Neko Shigure?)[27] - The user leaps into the air and performs multiple arched slashes in quick succession.

Sixth Form: Cat-Legged Winds of Love (陸ろくノ型かた　猫ねこ足あし恋こい風かぜ, Roku no kata: Neko Ashi Koi Kaze?)[29] - The user fully extends their sword to perform an arcing slash before retracting it and extending it once more, done in quick succession to form a layers of slashes.

Appearance: Obanai is a young man of short stature, pale skin complexion, and a fairly muscular build. He has straight-edged black hair of varying lengths, the longest reaching down to his shoulders and the shortest stopping at his cheekbones, which he wears down with two shorter strands hanging between his eyes. His eyes are almond-shaped and tilt upwards on the far sides, and are unique colored due to Obanai possessing heterochromia—his right eye is yellow and his left eye is turquoise. He is partially blind, barely able to see out of his right eye.[4]

Obanai's mouth is usually hidden by the bandage he wears over his lower face to hide his large facial scars, which were the result of his family horrifically cutting open his mouth to resemble that of a snake's gape.[5]

He wears a navy blue version of the standard Demon Slayer uniform, along with a black and white striped haori, the hem and cuffs of which are striped length ways rather than vertically, which covers his hands. Obanai also sports bandages in place of the leg-wraps around his calves giving the resemblance of kyahan, as well as another set of bandages that cover his mouth, and white with blue-strapped zōri on his feet. He is also always seen with his white snake, Kaburamaru, wrapped around his shoulders.

Obanai is a very harsh and strict individual who shows no concern for those who do not abide by the rules of the Demon Slayer Corps. His expectations for his fellow Demon Slayers are quite unrealistic, as he was seen berating Tengen Uzui for suffering heavy wounds against the "weakest" Upper Rank and telling him to "fight to the death" when Tengen insists on retiring. Tengen's retirement also highlights Obanai's devotion to the future of the Demon Slayer Corps, often at others' expense, such as when he ties up lower-ranked Demon Slayers and uses them as obstacles during Hashira Training for relatively petty reasons. He also sees the newer Demon Slayer recruits as weak and incapable of improvement, expressing extreme surprise when Tengen informs him that Tanjiro Kamado survived the battle with Daki and Gyutaro. Obanai has a rather prominent habit of pointing at people with his finger in an accusatory manner while berating them or talking badly about someone. Despite his merciless personality, there are two people he cares deeply about: Kagaya Ubuyashiki and Mitsuri Kanroji. He has a crush on Mitsuri, as he often lets his feelings shine through by sharing meals with her and giving gifts, such as the signature green socks she wears with her uniform. Obanai seems to let his overprotectiveness of Mitsuri show at times, such as when he threatens Tanjiro for growing too close to her.[7] It was implied that he has a crush on Mitsuri because of her cheerful personality that didn't let any of the hellish training she had gone through to radiate in the slightest. Talking with her also made him forget all the strife and conflict he had encountered during his past and made him feel as if he was an ordinary young man.[8] Like all the Hashira, Obanai has a great deal of respect for Kagaya too.

First Form: Winding Serpent Slash (壱いちノ型かた　委い蛇だ斬ぎり, Ichi no kata: Idagiri?)[26] - The user moves like a slithering snake and releases several slashes in a winding pattern.

Fifth Form: Slithering Serpent (伍ごノ型かた　蜿えん蜿えん長ちょう蛇だ, Go no kata: En'en Chōda?)[30] - The user curves their sword in multiple directions and slices their opponent, making it capable of decapitating multiple enemies at once.

Appearance: Sanemi is a tall man of very muscular build, with spiky long white hair and large almond-shaped eyes with purple irises. His face and body are covered with scars, accrued over his many years of fighting demons. He cuts his hair short somewhere in between the Rehabilitation Training Arc and the Mugen Train Arc. He is usually seen wearing a crazed expression on his face.

He wears a green-tinted version of the standard Demon Slayer uniform, unbuttoned to expose his chest and abs with a white long sleeved shirt over it with the kanji for kill (殺さつ, satsu?) etched on the back, white buckles around his shins and tabi socks with a pair of white zōri with green straps.

Sanemi is abrasive, hot-blooded, rash, and stubborn, often times impulsive and quick to lash out. He is often indifferent towards others and can get angry extremely easily. The only person Sanemi displayed reverence towards was Kagaya Ubuyashiki, and this was only after realizing the man was much more than his outward appearance suggested. Sanemi has also displayed a hunger for battle, wishing that he could encounter Upper Rank demons and proclaiming his excitement in fighting Upper Rank One, Kokushibo.

Sanemi's cold, rude, and dismissive behavior is the result of losing too many people he cared about in the past. Later, when he sees those people who have passed, such as his mother, he can't help but give her a smile to be able to see her again. When Genya joins the Demon Slayers in search of him, Sanemi repeatedly dismisses and lashes out during any chance of seeing him, but Tanjiro Kamado is able to tell Sanemi didn't truly hate him; and in fact still bore the same brotherly love he had for him in childhood. This was however never expressed outwardly as he tried to push Genya away from him and the Demon Slayers so he wouldn't be exposed to danger.

First Form: Dust Whirlwind Cutter (壱いちノ型かた　鹿じん旋せん風ぷう・削そぎ, Ichi no kata: Jin Senpū - Sogi?)[14] - The user dashes forward at blinding speeds and slashes continuously in a horizontal cyclone pattern. Second Form: Claws, Purifying Wind (弐にノ型かた　爪そう々そう・科しな戸と風かぜ, Ni no kata: Sōsō - Shinato Kaze?)[15] - The user lifts the sword upwards towards the right, above their head and unleashes four vertical slashes at once down on the enemy resembling claws. Third Form: Clear Storm Wind Tree (参さんノ型かた　晴せい嵐らん風ふう樹じゅ, San no kata: Seiran Fūju?)[16] - The user unleashes a whirlwind of slashes around their body that can defend them from incoming attacks and slice up their surroundings. Fourth Form: Rising Dust Storm (肆しノ型かた　昇しょう上じょう砂さ塵じん嵐らん, Shi no kata: Shōjō Sajinran?)[17] - The user releases several slashes above them from below their target.

Eighth Form: Primary Gale Slash (捌はちノ型かた　初しょ烈れっ風かざ斬きり, Hachi no kata: Sho Rekkaza Kiri?)[21] - The user leaps into the air and swings their blade horizontally, creating circular torrents of wind that slice up the opponent instantly. Ninth Form: Idaten Typhoon (玖くノ型かた　韋い駄だ天てん台たい風ふう, Ku no kata: Idaten Taifū?)[22] - The user backflips into the air and while upside-down, unleashes a powerful gust of circular wind that slashes apart anything below.

Appearance: Kyojuro was a young adult of tall stature and lean-muscular build. He had long bright yellow hair with red streaks akin to flames along with two shoulder-length bangs and two chin-length bangs on the side of his head, black forked eyebrows, and golden eyes that fade to red with white pupils. He was known to be charismatic and had an air of great optimism, having an enthusiastic smile plastered on his face nearly all the time.

Kyojuro wore a paler brown version of the regular Demon Slayer uniform, which consisted of a brown gakuran jacket, a white belt around his waist and tattsuke-hakama pants. Over this, he wore a haori with a white-yellow gradient pattern and red flame-like ridges at the end that his father Shinjuro had once worn and more than likely his father had worn when they were the Flame Hashira respectively. Finally, he wore red kyahan with yellow flames erupting from the bottom-up, with pale brown tabi socks and a pair of white zōri with red straps.

Kyojuro was greatly enthusiastic in regard to his duties as a Hashira, and often came across as cheerfully eccentric. He was amiable, pure of heart, 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 his belief that those who were born strong have a duty to protect the weak.

Kyojuro also loved his family immensely, displaying great respect and worry towards his father, Shinjuro Rengoku, despite him growing slowly more aggressive and apathetic towards Kyojuro. He was incredibly encouraging and optimistic towards his little brother, Senjuro Rengoku, believing in him and wishing him the best no matter what. This was further accentuated during his death where his final words for his father and his little brother were "take care of your body" and "follow your dreams no matter what". Kyojuro also believed that if someone lacks immense skill, their hard work towards their dreams and desire to help people doesn't count for nothing.

First Form: Unknowing Fire (壱いちノ型かた　不知火しらぬい, Ichi no kata: Shiranui?)[25] - The user charges towards their target at high speeds and unleashes a singular slash that aims to decapitate them. Second Form: Rising Scorching Sun (弐にノ型かた　昇のぼり炎えん天てん, Ni no kata: Nobori En Ten?)[26] - The user releases an arching sword slash upwards. Third Form: Blazing Universe (参さんノ型かた　氣き炎えん万ばん象しょう, San no kata: Kien Banshō?)[16] - The user swings their blade downwards in an arc. Fourth Form: Blooming Flame Undulation (肆しノ型かた　盛せい炎えんのうねり, Shi no kata: Sei En no Uneri?)[27] - The user swings their blade in a circular motion that is used to defend from incoming attacks or slash multiple targets in one swoop. Fifth Form: Flame Tiger (伍ごノ型かた　炎えん虎こ, Go no kata: Enko?)[28] - The user performs a series of powerful sword slashes that seemingly takes the form of a flaming tiger. Ninth Form: Rengoku (玖くノ型かた　煉れん獄ごく, Ku no kata: Rengoku?, lit. Ninth Form: Purgatory)[29] - The most powerful Flame Breathing technique. The user takes a high stance with their sword before dashing forward at high speeds. The technique is powerful enough to completely carve out the ground in its wake. In the movie and anime adaptation, this technique seemingly took the form of a flaming Japanese dragon that envelopes the user as they are charging towards the target.

Appearance: Tengen is a very tall, broad-shouldered, and muscular man with lightly-tanned skin and white hair. His hair is of an uneven length, the longest strands reaching his shoulders, and is styled with three more notable, shorter clumps arching up to fall as bangs between his eyes and on either side of his face. He has quite thin, maroon eyes that appear to slant inwards, each with one long eyelash flowing to the far side of his face. He is considered very attractive as noted by many women and even by Zenitsu; this has led him to use his looks as a tool for his missions whenever persuasion is necessary. During his days serving the Demon Slayer Corps, Tengen wears a sleeveless and dark turquoise version of the standard Demon Slayer uniform, along with a wrap of burgundy cloth around his calves with his tattsuke-bakama pants tuck in, and white-strapped Zōri. He also wears two thick, golden rings around his upper arms and what appear to be a pair of finger-less blue gloves, secured around his middle finger with a band of white and his wrists with another set of thinner gold rings, this time with two on each side.

As well as this, Tengen sports a white head-wrap that covers his hair, leaving only a thin ponytail visible to fall behind his head from between its layers, which is adorned with a large headband of pale gray that's decorated by six light pink gemstones, three large and arranged in a line, and three small and arranged in a triangle to the far left. A chain of smaller, pale blue gemstones hangs from each side of this headdress, framing his face, and he also wears what looks to be red eye make-up around his left eye, consisting of alternating large and small dots that run inwards, towards his eye.

Tengen is an eccentric and flashy individual, always wanting to be "flamboyant", possessing a need for everything to be flashy and outstanding, even proclaiming that he is the god of flashiness and festivals. This is shown when he gets excited imagining how "flamboyant" it would be if Tanjiro Kamado's blood vessels exploded, and tries to forcefully haul Aoi Kanzaki off to the Entertainment District with him so she can unwillingly help him with a dangerous mission, even spanking her.[7] As a result of his exuberant and flamboyant personality, Tengen is very demanding of others, treating the Demon Slayers very harshly during Hashira Training and insulting them for having no substance when they couldn't survive his stamina training.[8] Furthermore, he also abhors the idea of unflashy things, as shown when the Hashira openly expresses his hate for plainness.[9]

First Form: Roar (壱いちノ型かた　轟とどろき, Ichi no kata: Todoroki?)[41] - The user lifts their twin swords above their head and slams them down with great force, causing a loud sound resembling thunder as a result. Fourth Form: Constant Resounding Slashes (肆しノ型かた　響きょう斬ざん無む間けん, Shi no kata: Kyōzan Muken?)[42] - The user holds their twin swords apart and spins them rapidly around themselves, enabling the blades to destroy anything it makes contact with for powerful defensive capabilities around the user. Fifth Form: String Performance (伍ごノ型かた　鳴めい弦げん奏そう々そう, Go no kata: Meigen Sōsō?)[43] - The user holds the chain of their twin swords and rotates the blades at high speed while charging forward. The spin of the blades without changing grip allows for continual slashes while still being in motion. Rising Kick (打うち上あげ蹴げり, Uchiage Geri?)[44] - The user takes a forward front-step followed by a high-rising side-kick launching their opponent into the air.

Appearance: Shinobu is a petite young woman with a slender short build and a fairly pale complexion. She has large bug eyes that lack pupils, only a haze of gradient purple, making her eyes appear similar to those of insects. She has very short black wavy hair that fades into dark purple at the ends, styled at the back of her head into a flat yakai-maki bun, fastened with a white, turquoise and light purple butterfly ornament. She has center-split, ear-length, voluminous curtain bangs that flow down to frame the sides of her face, with two slightly thinner chin-length locks of hair in front of her ears below them. She stands out among the more physically imposing Hashira due to her diminutive stature and small frame, which is later reinforced by her mentioning that she does not possess enough physical strength to decapitate a demon as the others do. According to Zenitsu, Shinobu is so cute, that she could make a living on her looks alone.

Shinobu wears a dark purple standard Demon Slayer uniform with gold buttons, consisting of a dark-purple tinted straight-lined black jacket and matching colored tabi socks and hakama pants, tucked into white butterfly patterned Kyahan fading into pale turquoise then pink around her lower legs, fastened with white ribbons. Over her uniform, she wears a white haori that previously belonged to her older sister, which has a butterfly wing pattern, specially that of a Monarch Butterfly, that fades into a pale turquoise then pink color gradient on the sleeves and hem which are cuffed with a black and white dotted trim. She wears white zōri sandals with purple straps for footwear, with a hidden blade in one of the heels.

When Shinobu was fourteen, her appearance was altered slightly. Her chin-length strands of hair in front of her ears were tucked in, and she had a different Demon Slayer uniform consisting of silver buttons and cloth a darker shade of purple. She also sported a plain white haori over it.

Shinobu displays a bright, friendly and cheerful demeanor, always having an easygoing smile on her face regardless of the situation she is in. However, her outward behavior is shown very quickly to be a façade. This is displayed in the way she enjoys teasing others, to the point of being rather sadistic about it, enjoying most notably to pick on Giyu Tomioka.[4] Despite her relaxed exterior and her initial claim of wanting to get along with demons, she can be rather cruel towards them, which is seen when she kills Daughter after giving her false hope of helping her, and immediately attempting to kill Nezuko Kamado without giving Tanjiro Kamado a chance to prove that she was harmless to humans.[5]Later on, she is shown to have a more compassionate side towards both Tanjiro and his sister after hearing their full story.[6] It is later revealed that her outwardly calm and tranquil disposition is worn as a mask, as Shinobu holds an intense hatred for demons due to the loss of her sister, Kanae Kocho, at a young age, along with the deaths of her parents, almost all of her Tsuguko, and the families of her apprentices at the Butterfly Mansion. This hatred is so strong that she is in a near-constant state of extreme anger,[7] which is sensed by Tanjiro Kamado when the two individuals hold a conversation. Her desire for revenge rendered her unable to live the normal life her sister had wished upon her, instead devoting the entirety of her energy to defeating demons.[8]

Butterfly Dance: Caprice (蝶ちょうノ舞まい　戯たわむれ, Chō no mai: Tawamure?)[37] - The user leaps into the air and charges towards the opponent, stinging them multiple times with their blade to inject poison in just seemingly one strike. Dance of the Bee Sting: True Flutter (蜂ほう牙がノ舞まい　真ま靡なびき, Hōga no mai: Manabiki?)[38] - The user dashes at their target at blinding speeds and uses the momentum of their speed to then strengthen a single thrust into their opponent and inject poison into them. Dance of the Dragonfly: Compound Eye Hexagon (蜻せい蛉れいノ舞まい　複ふく眼がん六ろっ角かく, Seirei no mai: Fukugan Rokkaku?)[30] - A six strike attack with which the user aims to strike and inject their target with multiple doses of poison at the target's weak spots (such as the neck, heart, torso, etc.) in order to kill them with a large dose of poison. Dance of the Centipede: Hundred-Legged Zigzag (蜈ご蚣こうノ舞まい　百ひゃく足そく蛇じゃ腹ばら, Gokō no mai: Hyakusoku Jabara?)[39] - An attack with which the user uses their full speed to run a zigzag pattern that confuses their opponent in order to create an opening for them to directly stab their opponent's neck and inject poison to kill them, with the stab's force and power being further enhanced by the momentum of their speed. Doma noted that the sheer speed of this technique is strong enough to destroy an entire wooden bridge.

Appearance: Gyomei is a hulking figure among the Demon Slayers. He is one of the tallest characters in the series, easily towering over his fellow Hashira. He is powerfully built and extremely muscular. He has spiky black hair and a prominent scar running horizontally across his forehead. Having been blind since childhood, he has white eyes with no visible irises or pupils. His eyes frequently tear-up when he gets emotional.

Gyomei wears a black and white uniform typical of a Demon Slayer, with bandages over his shins resembling kyahan and white zōri with an olive green happi draped over his shoulders. The collared frame of the happi contains the kanji for the Japanese Nianfo/Shin Buddha chant (南な無む阿あ弥み陀だ仏ぶつ, Namu Amida Butsu?) from the top-down, along with the separate kanji all over at the back. He also sports a large-beaded necklace around his neck and carries a set of ojuzu beads when he is not engaged in battle.

Gyomei embodies the gentle giant archetype, being surprisingly soft-spoken and sensitive, despite his outwardly intimidating appearance. He is also shown to be quite pious, carrying his prayer beads at all times and offering prayers in poignant situations. Most notably, Gyomei easily cries over the most insignificant things, accentuating his rather soft nature. This could be due to his love for all living creatures brought about by his religious upbringing, and insinuated when he felt so disgusted by beating up a demon that he would never forget that feeling for the rest of his life.

Like the rest of the Hashira, Gyomei has a great deal of respect for Kagaya Ubuyashiki, of which no small part was due to the Oyakata saving his life. He is also one of the most respected individuals among the Demon Slayer Corps, not only due to being a member of the Hashira but because he serves as a symbol of hope due to his immense strength: Shinobu Kocho had once stated that when Gyomei fights, it puts everyone around him at ease.[7] Furthermore, Gyomei serves as a leader for them, as seen when he sat at the front during Hashira meetings and was often looked to for his word and opinion.[8] He was entrusted by Kagaya to give out orders to them, due to both Gyomei being the oldest and because Kagaya had known him for the longest out of anyone outside his own family.

Though he maintains a fairly reserved disposition, Gyomei harbors a very objective and somewhat suspicious view of the people around him, owing to his experiences before becoming a Demon Slayer. He is ever-cognizant of what others, particularly children or those younger than him, are capable of if given the opportunity. By reason of his doubtful nature, it can take a while for Gyomei to completely accept and trust others. When he does open up and let others in, he is unwavering in his commitment to them.

First Form: Serpentinite Bipolar (壱いちノ型かた　蛇じゃ紋もん岩がん・双そう極きょく, Ichi no kata: Jamongan - Sōkyoku?)[31] - The user throws both the flail and axe towards their intended target and manipulates the chain by rotating it thus causing the axe and flail to also rotate in order to drill and grind right through their target. Third Form: Stone Skin (参さんノ型かた　岩がん軀くの膚はだえ, San no kata: Ganku no Hadae?) [33] - The user unleashes a series of slashes with their axe deflecting nearby attacks. Fourth Form: Volcanic Rock, Rapid Conquest (肆しノ型かた　流りゅう紋もん岩がん・速そく征せい, Shi no kata: Ryūmongan - Sokusei?)[34] - The user manipulates both the flail and axe weapons at both ends of the chain by swinging the chain on both sides in order to strike their opponent using a two pronged wide ranged attack. Fifth Form: Arcs of Justice (伍ごノ型かた　瓦が輪りん刑ぎょう部ぶ, Go no kata: Garin Gyōbu?)[35] - The user utilizes a powerful barrage with their flail and axe, doing a great amount of damage. The axe is destined to hit first with the trajectory of the flail following from the opposite side and slamming into the opponent.

Appearance: Muichiro is a young boy of fair skin and short stature with a lean muscular build along with long, straight hair of a black color that fades to soft cyan as it approaches his waist. He wears his hair loose with two clumps protruding slightly from each side of his head, a set of marginally shorter hair left down to frame his face, and unruly bangs over his forehead. He also possesses large, empty-looking soft cyan eyes. He is identical in appearance to his older twin brother Yuichiro.

Following his meeting with Tanjiro Kamado and the return of his childhood memories, Muichiro's once empty looking eyes seem to now have a hopeful glimmer that is accompanied with a more upbeat and cheery expression, reminiscent of his former demeanor before the death of Yuichiro.

Muichiro wears a dark, slightly turquoise-tinted version of the Demon Slayer uniform. His uniform has longer, looser sleeves that are more reminiscent of those of a kimono than of the standard cuffed uniform. Along with this, the lack of bands of cloth wrapped around his calves gives his uniform an overall loose and sizable appearance. He also has dark blue tabi socks and a pair of white zōri with dark blue straps.

When Muichiro was young, he wore a light, sleeveless yukata with a light blue mist design, similar to the darker one his brother wore when they were both ten.

Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus on anything. Impassive and, at times, obtuse, he tends to think only for himself and operates on logic alone, never letting emotions guide him, making him seem seemingly apathetic and indifferent. However, Tanjiro Kamado sensed that Muichiro wasn't being apathetic on purpose as he didn't emanate any animosity. Despite his mostly uncaring and unserious demeanor, he has been shown to become serious when it is required and is devoted to his position as the Demon Slayer Corps' Mist Hashira. Alternatively he seems to display a cold and arrogant side; as shown by him violently shaking down Kotetsu and calling him stupid, saying his time as a Hashira was important, more so than his own, and that all that the swordsmiths could do was make weapons. Despite this, Muichiro doesn't seem to be indifferent towards Kagaya Ubuyashiki, most likely due to his immense respect for his master. However, before the death of his twin brother when the siblings were eleven, Muichiro's personality was that of a much more compassionate and optimistic individual, the polar opposite of his current disposition. Having originally taken after his father, he was shown to display a higher level of kindness and understanding, believing he should aim to do good for others if he wanted good to be done for him. When told by Amane Ubuyashiki that they were descendants to Demon Slayers of old, Muichiro became excited at the prospect of being able to protect people.

After his brother was attacked by a demon and witnessing his final moments and death, Muichiro subsequently lost his memories and has held an omnipresent rage deeply suppressed inside of him that inevitably drove his future, intense training. After this memory loss, he started exhibiting the indifferent attitude of his twin brother he is now known for as a Hashira.

Second Form: Eight-Layered Mist (弐にノ型かた　八や重え霞かすみ, Ni no kata: Yaekasumi?)[32] - The user performs eight slashes in quick succession. Third Form: Scattering Mist Splash (参さんノ型かた　霞か散さんの飛し沫ぶき, San no kata: Kasan no Shibuki?)[33] - The user performs a powerful and swift circular slash that can blow away incoming projectiles. Fourth Form: Shifting Flow Slash (肆しノ型かた　移い流りゅう斬ぎり, Shi no kata: Iryūgiri?)[34] - The user takes a low stance before dashing toward the target and slashing them. Fifth Form: Sea of Clouds and Haze (伍ごノ型かた　霞か雲うんの海うみ, Go no kata: Kaun no Umi?)[35] - The user charges at their target at blistering speeds in a zig-zag motion while performing a barrage of continuous slashes in front and/or around them. Sixth Form: Lunar Dispersing Mist (陸ろくノ型かた　月つきの霞か 消しょう, Roku no kata: Tsuki no Kashō?)[36] - The user leaps into the air and performs a multitude of slashes in a somersaulting motion, decimating dozens of targets at once. Seventh Form: Obscuring Clouds (漆しちノ型かた　朧おぼろ, Shichi no kata: Oboro?)[37] - The personal creation of Muichiro. A movement-based technique designed to heavily disorientate the target, which is done so by fluctuating the user's tempo. When the user appears before the target, they move incredibly slow, but then accelerate to blistering speeds before getting hit, making it seem like they disappeared into a cloud of mist. When done repeatedly, it can disorientate the target to the point of making them think they are being covered in a thick layer of mist.
