Demon Slayer Corps

The titular central protagonistic faction of the series, the Demon Slayer Corps (Kisatsutai in Japanese) are a large group of warriors, founded by the Ubuyashiki Clan, that are dedicated to one purpose of their existence: Protecting humanity by slaying down demons. Like demons, they have existed since the Heian Era and they remained as a secret organization since they weren't officially acknowledged by the government, thus making their existence unknown to the world. Their main weapons of killing demons are Nichirin Swords, blades made of Scarlet Iron Sand and Ore.

In General

As Long as There Is One Man: The basis of the ideal held by Kagaya Ubuyashiki, and accepted by all of those who respect his wishes within the Corps. Humans are frail against the mighty demons, but we are determined beings as Kagaya puts it, no matter how many slayers fall in battle the combined will of their hope for demonkind's downfall has endured for centuries, strengthening the following generation of slayers to pick up from where the previous one left off. Said verbatim by Kagaya in his only and final meeting with Muzan Kibutsuji, as the sickly leader of the demon slayer corps lured the demon king to be entrapped by a massive explosion, a suicide attack by Kagaya and most of his family.
Combat Pragmatist: The Demon Slayers Corps are known for one common thing: They don't tend to fight fair. Because demons have such overwhelming powers and advantages such as unlimited stamina and a Healing Factor, they're willing to trick their enemies with dirty tactics and will pull out any stops to kill a powerful demon. This is best seen in the Final Battle against Muzan, who's suffering from multiple drugs. Every surviving Slayer gangs up on him once he's been sufficiently weakened by the Hashira to make sure that he can't escape the sun.
Creature-Hunter Organization: The Demon Slayer Corps have existed since the Heian Era and for thousands of years, they have been fighting the demons to protect humanity.
Demon Slaying: It's their main profession after all.
Determinator: The Demon Slayers ultimately becomes this during the Final Battle against Muzan Kibutsuji, as many members of the corps bravely give their lives to protect the remaining Hashira and to put an end to the Demon King once and for all. In the end, their sacrifices paid off, as Muzan has finally met his end.
Earn Your Happy Ending: Majority of the Demon Slayer Corps had faced many hardships during their war against the demons. But now with Muzan Kibutsuji finally for good, they can finally live out the happy life they ultimately desire, and this time, with no demon interfering with their lives.
Elemental Powers: Downplayed. The Breathing Styles are swordfighting styles that take inspiration from them. The basic Breathing styles are Water, Flame, Wind, Stone, and Thunder, with several users being able to mix and match the styles to create their own elemental styles. However, they don't really grant the users elemental powers, they are merely just sword techniques that imitate them. While there are elemental visual effects whenever the characters use their Breathing Styles, it's purely for visual appeal.
Fantastic Racism: Majority of the Demon Slayers (Especially the Hashira) have great hatred towards demons, with several of them having a personal vendetta against all of them. Because of this, it would be rather rare to see a Demon Slayer who shows kindness towards demons.
Heroic Sacrifice: During the Final Battle, dozens of Demon Slayers bravely sacrifice their lives to save the Hashira to ensure their survival so they can defeat Muzan, with one of them stating to protect the Hashira, as they did before. Their deaths enrages the Hashiras and strengthen their determination to stop Muzan once and for all.
Katanas Are Just Better: Majority of the Corps' members use katanas as their main primary choice of weapons. Although some are special exceptions, such as Gyomei Himejima, who uses a steel chained flail-axe and Tengen Uzui, who uses dual cleavers.
Not Afraid to Die: Many members of the corps knows they will not survive their battle against Muzan Kibutsuji but they still bravely stand their ground and continue their fight against the Demon King.
The Order: The corps serves as a secret militia group created by the Ubuyashiki Clan on the purpose of protecting humanity by slaying down demons. At first, they were just a group of normal swordsmen and they weren't at their strongest at the time, but in the Sengoku Period, they were blessed with the arts of Breathing Styles, which made them acquire more physical abilities on killing demons.

Leader

Kagaya Ubuyashiki

Voiced by: Toshiyuki Morikawa (Japanese), Matthew Mercer (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/kagaya_anime.png

"I know what eternity is. Eternity is a human feeling. Only human feelings last forever and are undying."

The blind leader of the Demon Slayer Corps and 95th of his line.

Absurdly Youthful Father: Kagaya is 23 in the present story, and his oldest son is 8, meaning he was 15 when his first son was born. He has two daughters that are older than Kiriya, making him a father at the age of 14, the same age he was married at. The 2nd Databook alleviated this by confirming all of his five children are quintuplets, so Amane only got pregnant once.
All There in the Manual: The second Databook explains that Kagaya and Amane's children are quintuplets. It could be assumed, since they look so similar, but it is never brought up in the story proper, and it would be harder to assume which are older/younger.
Batman Gambit: Knows Muzan will make his move after observing Nezuko's ability to withstand sunlight, allowing him to be drawn in so Kagaya can give his life to wound him, setting the stage for the final battle.
Benevolent Boss: In stark contrast to Muzan, Kagaya is not only a reasonable leader, he's also connected to his underlings emotionally with a parental bond.
Big Good: As the leader of the Demon Slayer Corps, he definitely counts.
Blind Seer: Though he is blind, he has an impeccable sense to predict future events through instinct. This is something that all heads of the Ubuyashiki family develop, and has been used for generations to build the family's wealth and avoid disasters.
The Chessmaster: Kagaya has set up a complex scheme for keeping key locations safe from Muzan's demons, involving multiple guides and constantly changing routes to throw them off for years.
The Dead Have Names: He memorizes the names, faces, and backgrounds of every single Demon Slayer who dies.
Defiant to the End: He makes sure to talk directly to Muzan's face about what he thinks of him and his dreams before the hidden bomb goes off.
Emotion Control: Tanjiro realizes that when Ubuyashiki speaks to him, he feels relaxed, uplifted, and much more inclined to do what he says. This ability is so powerful that even Muzan is briefly affected by it.
A Father to His Men: He is a living saint and adores the Demon Slayers like his own children, treating them like treasured family more so than subordinates.
Facial Horror: Oh boy. As part of the Ubuyashiki's curse Kagaya's forehead is shriveled and a pale lavender color. It's shown that the disease was gradual and by the end of his life right before his Heroic Sacrifice, it spread to the entirety of his head, also darkening his pupils.
Good Counterpart: To Muzan. Muzan is the Demon King, while Kagaya is the master of the Demon Slayer Corps. Kagaya is a Benevolent Boss who would treat his soldiers as if they were his children. Muzan on the other hand is a Bad Boss that would abuse his subordinates when they become of little to no use for him. What makes this even more jarring is that both men are part of the same bloodline, making them distant relatives of each other.
Good Parents: While he can be a bit strict with them, it's clearly obvious Kagaya loves his children very much.
Go Out with a Smile: Muzan describes Kagaya's final expression before his death as that of a smiling buddha. This is the complete opposite of Muzan, who deeply fears death and would do anything possible, no matter how reprehensible or undignified, to avoid facing it.
Guile Hero: Because he's incapable of getting martial art training, Kagaya settles for fighting back against Muzan by setting up plans in leading the Corps. He also draws Muzan into a trap using his own life as bait, before blowing himself up to wound the demon leader.
Happily Married: Kagaya and Amane clearly have genuine love between them, as Amane stays by his side and nurses him when his health gets worse. Amane even shows panic and worry when he begins coughing out blood from his mouth. In fact, back before they were married, Kagaya (Who was 13 years old at the time) only agreed to married Amane, on the condition that she cares for him on her own free will, showing how much Kagaya cares for her.
The Heart: He's not just the leader of the Demon Slayers, he's their moral center, too.
Hereditary Curse: The illness that is killing him is said to be a curse caused by his family producing Muzan, every male is cursed to die young in great pain.
Heroic Sacrifice: When he's too sick to live for much longer he uses himself as bait to lure in Muzan Kibutsuji, sacrificing himself, along with his wife and two of his daughters in an explosion to ensnare Muzan and bring in the Hashira to finish Muzan once and for all.
Incurable Cough of Death: The members of the Ubuyashiki family are afflicted with a wasting illness that tends to kill them before they hit 30, and Kagaya is no different.
Loved by All: Kagaya was deeply loved and respected by many in the Demon Slayer corps, including by the likes of Gyomei, Sanemi, and Obanai. When he sacrifices himself to weaken Muzan, everyone in the corps were sadden and/or angered by his demise.
Nerves of Steel: The man faces off with the most evil demon alive without a flicker of worry and lures Muzan into a trap, never breaking his composure for an instant while giving him a soft-spoken The Reason You Suck speech on how Muzan will never be able to achieve his goal of finding Nezuko and absorbing her to conquer the sun and how everyone is ready to fight him.
Nice Guy: Kagaya is one of the kindest men alive. He refuses to treat Nezuko as a monster, is kind to Tanjiro, and loves every member of the Demon Slayer Corps like his own children.
Nice Job Breaking It, Hero: Kagaya teaching Muzan the importance of leaving behind a legacy would cause a threat far greater than Muzan himself to be unleashed upon the world, a Sun-immune demonized Tanjiro. This threat was luckily swiftly dealt with through the use of the humanification medicine that was administered by Kanao.
Non-Action Guy: Kagaya has no martial ability whatsoever. He mentions he once tried to wield a sword and couldn't even swing it ten times without feeling like his heart would burst.
O.O.C. Is Serious Business: Kagaya is kind to a fault, but the only time this drops is when he lays viciously into Muzan with what he truly thinks of the depraved villain.
Parental Substitute: Later in the series, it is properly explained the relationship between him and the slayers. Early on, Kagaya can be seen calling the hunters “children”, which eventually is shown that Kagaya means that the slayers are his children since quite many of them are orphaned. He, being the leader of the Demon Slayers, naturally employed a lot of orphaned people with a burning desire to kill demons; the strongest slayers, in particular, the Hashira, are even closer to Kagaya, showing the utmost respect towards him. Two of them, Himejima and Tokitou, outright called Kagaya their second father; financially speaking, Kagaya even shares his vast wealth as a means to pay the slayers. The Hashira can even be considered his heirs to an extent, as Kagaya gave them a good piece of land and a big house to those who are orphans and had no inheritance of their own.
Perfectly Arranged Marriage: Heads of the Ubuyashiki family have been arranged to marry the daughters of priests from a nearby shrine for generations. Kagaya and his wife Amane are no different and have unconditional love for each other.
Reasonable Authority Figure: As opposed to some of the Hashira's Fantastic Racism towards Nezuko, Kagaya bears no ill will towards a Demon Slayer accompanying his demon sister, although he wants Tanjiro to understand that not all people will accept his unique situation due of how most of the members of the corps are victims of Demon attacks. And it's heavily implied that he even lets Tamayo (another demon) help him and the corps on taking down Muzan once and for all, given how she also collaborates with Shinobu on returning Nezuko back to human and create the medicine to bring their shared nemesis down.
Together in Death: His wife and two eldest daughters choose to die with him in his suicide attack against Muzan.
Universally Beloved Leader: He's respected and liked by everyone in the Corps for his kind personality and leadership skills.
Wise Beyond Their Years: Kagaya is a man of deep wisdom, far more than befits his age of only twenty-three. He's seen as far wiser and more mature than men many years his senior. The most notable thing is the fact Kagaya managed to make Himejima, who’s four years older, consider him, the younger person, to be his father figure.
You Cannot Kill An Idea: As he is confronted by Muzan, Kagaya informs him that even if he is killed, his will to stop Muzan will live on through the remaining members of the Demon Slayer Corps. He considers thoughts to be indestructible feelings that can be inherited and passed on by those that come after, something that a selfish being like Muzan could never understand. Kagaya laying out that the demon race will die off along with Muzan thanks to his selfishness makes him lose his composure and slip into an expression of sadness, something that Kagaya picks up on despite his blindness and uses to alter the power dynamic of their confrontation even though he is a helpless, dying man.
- This ends up zig-zagging with Gone Horribly Right during Muzan's own final moments, as he genuinely took Kagaya's words to heart and witnessed firsthand how powerful inherited thoughts and wills can be over the course of the final battle. Muzan twists and perverts Kagaya's sentiment into his own selfish interpretation, and decides to pass on his will to destroy the Demon Slayers by resurrecting the deceased Tanjiro into a demon as his final act, cruelly forcing him to carry on his legacy and keep the demon race alive as its new king. However, Muzan's failure to understand that he needs people who genuinely want to carry on his will by being an example to them, like Kagaya (and heavily implied, to his predecessors as well and including his son and successor Kiriya) inspiring hope and wisdom to the Demon Slayers who were once left nothing when Demons ruined their lives had proven from time to time, ends up ruining his attempt to keep his legacy alive, as Tanjiro wanted nothing to do with being an all-powerful demon and resisted Muzan the moment he was able to. Considering that Muzan's a Bad Boss and an abhorrent sociopath, he will never reach the same understanding as Kagaya in regards to this trope.

The Successor (Spoiler)

Kiriya Ubuyashiki

Voiced by: Aoi Yūki (Japanese), Christine Marie Cabanos (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/ubuyashiki_kiriya.png

^{Click here to see him as leader of the Demon Slayer Corps.}

One of Kagaya's children and the only son among the quintuplets. After the death of his father, he becomes the new leader of the Demon Slayer corps.

Ascended Extra: He first appeared during the Final Selection as the black-haired "girl". He didn't get a significant role since then until he succeeds his father after his Heroic Sacrifice.
Babies Ever After: According to the datebooks, Kiriya ended marrying and having children, and he spends his days hugging them along with his two surviving sisters during his 20s and 30s crying Tearsof Joy, due to realizing the Ubuyashiki curse was finally over.
Big Good: After the demise of his father, he quickly becomes the new leader of the Demon Slayers during the final battle against Muzan and the Upper Rank demons.
A Child Shall Lead Them: He becomes the leader of the Ubuyashiki family at the tender age of eight.
Dude Looks Like a Lady: He initially looks not much different from his sisters. However, in later chapters, he appears more masculine. It turns out every boy of the Ubuyashiki family is groomed like a girl until they reach a certain age.
Earn Your Happy Ending: With Muzan and the demons gone for good, Kiriya disbands the Demon Slayer Corps and finally gets to live a normal life as a child. To take this further, the Ubayashiki curse is broken, and Kiriya is still alive by the events of the epilogue.
Hereditary Curse: The first in his family not to be inflicted by the illness of his forefathers, as Muzan dies shortly after he inherits the role as Head of the Demon Slayers. Having finally atoned, Kiriya lives for a really long time and is even still alive as the oldest man in Japan in the Distant Finale.
It's All My Fault: In chapter 181, Kiriya blames himself for not being able to prevent the rookie Demon Slayers from encountering Muzan and briefly gets overwhelmed by fear and doubt. His younger sister slaps his face to snap him out of his overwhelmed state. He then regains his composure and orders all of the Demon Slayers to regroup before thanking both of his younger sisters afterwards.
Massive Numbered Siblings: He has two older sisters and two younger sisters.
Not So Stoic: Normally composed and focused, but in chapter 180, he loses his composure when the rookie Demon Slayers suddenly encounter Muzan's cocoon and ordered them to retreat.
Post-Victory Collapse: He collapses from exhaustion after Muzan is finally defeated.
Sole Survivor: Since Yushiro is an immortal demon, Kiriya is by default the last surviving major character from the Taisho era that is a human.
Significant Wardrobe Shift: He changes from his feminine clothing to that of his father, once he succeeded him as the leader of the Demon Slayer Corps.
Strong Family Resemblance: He looks nearly identical to his sisters, except with black hair.
Take Up My Sword: Kiriya is given the role of commander of the Demon Slayers after his father self-destructed to weaken Muzan. He takes the job seriously and tells his sister not to cry and not give up while assisting the Demon Slayers in their battle against Muzan and his Demons. Although the extra chapters reveal that he secretly feels saddened for his father.
Wholesome Crossdresser: In the Volume 6 extras, it was revealed Kiriya is really a boy dressed as a girl. It's because the boys in the Ubuyashiki family are sickly, so they have to raise them as girls until the age of 13.
Wise Beyond Their Years: A capable commander and strategist, all at the age of eight years old.
You Are in Command Now: He becomes the head of the Demon Slayers with the death of his father and elder sisters.

Kanao Tsuyuri

Voiced by: Reina Ueda (Japanese), Brianna Knickerbocker (English)^{Other VA}

^{Click here to see her updated, late series' design.}

"Somehow, I feel the people I care for and those important to me will still be alive tomorrow. But that's just my hope and there's no way I can promise that with any certainty. Why do people... believe such things?"

A young girl who is being trained as a "Tsuguko" (successor) to the Hashira, and is mentored by her adopted sister, the Insect Hashira, Shinobu Kocho. She partakes in and passes the same Final Selection as Tanjiro does. Kanao is a silent and emotionless Demon Slayer, who often relies on her coin to make decisions and often has trouble functioning without being told what she needs to do. This is because she suffers a traumatic past of being heavily abused by her parents, which caused Kanao to shut down her emotions. Despite being rescue from slavery and adopted by Kanae and Shinobu Kocho as her sisters, she still had trouble with acting on her emotions properly. That was until she met Tanjiro, with his influence changing Kanao for the better. Like Kanae, she is a practitioner of Flower Breathing.

Abusive Parents: Up to a horrifying level. Before they sold her, her parents constantly abused her and her siblings, with some of her brothers being killed because of it. They would even harshly punish them if they were to cry and/or make a sound of pain, which causes Kanao to become emotionless. The worst part is that they may never face the consequences of their horrible actions.
The Ace: Thanks to being Shinobu's Tsuguko, Kanao is leagues ahead of Tanjiro and company in terms of training, and she is the only member of Tanjiro's selection to be completely unharmed after the seven-day long Final Selection. During the Hashira Training Arc, she is the only one Tanjiro didn't eventually catch up with after he started late. The first demon we see her fight is Upper-2 Doma, the third strongest demon, and she's the one who restores a demonized Tanjiro at the series' climax. This oddly gets subverted upon the release of the 2nd Datebook, where it is revealed she is ranked Hinoto, just one below Tanjiro, Zenitsu, and Inosuke.
Action Girl: She's a very capable Demon Slayer.
Actually Pretty Funny: During the Spider Mountain Incident, she's given the task of exterminating all demons she comes across, including Nezuko, who has been prompted to flee by Tanjiro. While in pursuit of the demon girl, Kanao is surprised at the fact that Nezuko isn't attacking her, and when Nezuko reduces her size to dodge Kanao's attacks, Kanao can't help but smile at the ridiculousness of the whole situation and Nezuko's cuteness.
Adaptation Dye-Job: Gotouge isn’t consistent with giving Kanao the color gradient effect, as she has sometimes been drawn with pink hair tips, but she has also been drawn with just full black hair as well. The anime followed on giving her full black hair.
Animal Motifs: Butterflies like her mentor, Shinobu, though she uses the Flower Breathing instead of the Insect Breathing. She wears a butterfly-shaped hairclip, is sometimes seen with butterflies surrounding her, and is noted for her extraordinary eyesight, which is similar to butterflies having pronounced color vision. Using the Flower Breathing's final form, Equinoctial Vermillion Eye, makes her look even more insect-like.
Anti-Nihilist: Judging by how she speaks, Kanao is heavily implied to be nihilistic, as she believes nothing matters to her, so she can't really decide for herself. That being said, she's willing to fight for good purposes, and is capable of loving people that matters to her, such as in the case of Kanae, as Kanao joined the corps to avenge her death. She does seem to grow out of this nihilistic personality.
"It doesn't matter. Nothing matters to me so I can't decide for myself."
Arch-Enemy: Upper Rank 2 Doma, for killing her sister figures Kanae in the past, and Shinobu in the final battle.
Beauty Is Never Tarnished: Initially played straight, since she doesn't even have a scratch on her at the end of the Final Selection and is never shown to be injured during missions. Averted later in the Infinity Castle arc where her fight against Doma leaves her injured, heavily scarred and almost half-blind.
Because You Were Nice to Me: The reason she starts liking Tanjiro, as he effortlessly broke through the conditioning she had set with the coin flipping she uses to communicate by making her realize that she can just flip the coin to get the answers she wants, and it doesn't have to be a single coin flip, stating that he'll flip the coin as many times as necessary just to talk to her.
Berserk Button: The very existence of Doma is enough to break her calm demeanor. After killing Shinobu right in front of her eyes, her rage of him increases to a sadistic degree.
Beware the Nice Ones: Despite her emotionless nature, Kanao is a very pleasant and kind girl who greatly cares for others. That being said, she will not show mercy to any demon she faces against. Especially in the case of Doma.
Beware the Quiet Ones: Just because she rarely talks doesn't mean she doesn't know how to fight.
Big Sister Instinct: She tried preventing Tengen from forcibly taking Aoi and Naho on a dangerous demon-slaying mission without either of their approval. Kanao also shields Sumi from a bad fall with her body after Tengen's flash step launches everyone in the air.
Break the Cutie: Oh boy, Kanao sure had it rough. She had a very horrible past, living under an horrible abusive household, turning her into an emotionless girl and is sold into slavery, luckily gets rescued by the Kocho sisters, but some time later, Kanae gets tragically killed by the demon, Doma. Then, in the Final Battle, she loses Shinobu at the hands of Doma, now losing two of her sisters. After killing her mortal enemy, she holds the broken hairpin of Kanae and the hairpin of Shinobu, hearing their spirits and being told that they were very proud of her, causing her to shed tears. After every hell she's been put through, you would really want to give her a hug.
Broken Ace: Kanao was the strongest out of her batch in the Final Selection, being a tsuguko, but because of her Dark and Troubled Past she has difficulty functioning without being told what to do. It isn't until she befriends Tanjiro that she starts breaking out of her chains.
Character Development: In the beginning, Kanao was an quiet and emotionless character, mainly due to her trauma of living in a horrible household. But when she met Tanjiro, she suddenly began developing more emotions and doesn't often rely on her coin to make decisions, mainly because Tanjiro encouraged her to "follow her heart". This is most notable during the Entertainment District Arc, where she tries to stop Tengen Uzui from taking Aoi and Naho, without even relying on her coin.
- This is even more noticeable in the Swordsmith Village Arc. After Tanjiro awaken from his coma, two months following the fight with the Upper Six Kizuki demon, Kanao is greatly shocked before checking up on him. She then tearfully smiles, relieved to finally see him awake. When Tanjiro goes back to sleep, she tries to tell everyone (Inosuke, Aoi, Goto, and the Caterpillar Girls) that he fell back asleep, but since they couldn't hear due to them arguing, Kanao completely raises her voice so they can stop arguing and let Tanjiro sleep in peace.
Child Prodigy: Played with. She's been considered a Tsukugo even before becoming a Demon Slayer, as she's been training under Shinobu since she was very young. However, the main trio catch up to her relatively fast in spite of not receiving constant instruction from a Hashira like she has. Then Volume 19's Taisho Rumors shed a little light on this. As a child, she was naturally talented at demon slaying, having quickly learned Flower Breathing just from watching the Kocho sisters without having been formally trained to fight yet at the time.
Custom Uniform: She wears a knee-length pleated skirt and knee-high boots instead of the Demon Slayer Corps' standard hakama and sandals. This may have to do with her status as a Tsuguko.
Cute Mute: She's silent most of the time and a formidable Demon Slayer. Although, she slowly grows out of being silent and is slightly more sociable.
Dangerous Forbidden Technique: The final form of Flower Breathing: Equinoctial Vermilion Eye, grants Kanao far more pronounced dynamic vision, but has a heavy risk of Kanao going blind from her blood vessels rupturing and the nerves being overclocked. Even using it for a short time leaves her almost blind on her right eye.
Dark and Troubled Past: Kanao grew up in an abusive household before being sold as a slave. Her mind and emotions stopped functioning to cope with her situation.
A Day in the Limelight: From Chapter 157-163, she, alongside Inosuke Hashibira, are the main focus, as we follow their battle against their mortal enemy, Doma, as well as exploring more of Inosuke's origins and Kanao's overall growth.
Desperately Needs Orders: Because of her difficult past, she has a hard time functioning without being directly told what to do. Kanae gave her a coin to flip for whenever she has trouble making decisions by herself. Her Character Development focuses on her developing her own free will and not relying as much on her coin.
Did You Just Flip Off Cthulhu?: In the Final Battle, Kanao decides to insult Doma, calling him out for his lack of emotions and even questions his existence. Keep in mind, that Doma is the Upper 2 Demon, which makes him the third strongest demon in the series. And Kanao just decides to insults him, directly to his face with no sense of fear. This surprisingly even manages to piss off Doma, who drops his Faux Affably Evil nature and gets all serious.
Dull Eyes of Unhappiness: She had dulled eyes as a child, but being rescued by Kanae and Shinobu brought back the shine in her eyes.
Emotionless Girl: As a child, the trauma that she had gone through left her in a state void of emotions. Even after being rescued by Kanae and Shinobu, she still couldn't act on her own will and had to use a coin given by Kanae to make decisions. Her conversations with Tanjiro helped her recover from her emotionless state, and she can fully express her emotions, later on not having to rely on the coin anymore.
Family of Choice: Despite having a different family name (which she chose for herself, having been nameless beforehand), she considers the Kocho sisters to be her family, introducing herself as their little sister.
Foil: To Doma. Both of them had lacked the capacity to feel emotions growing up, Kanao due to her Dark and Troubled Past: born into an abusive household before being adopted by Kanae and Shinobu, while Doma was physically incapable of feeling them despite being born to parents that spoiled him and even started a religion based on him. Both of them started feeling emotions after they fell in love with someone, Kanao with Tanjiro, Doma with Shinobu in his final moments. Their fight against each other showcases just how much Kanao has changed since she met Tanjiro.
- There's also their different personalities. While Kanao is an silent and emotionless demon slayer, she possesses a kind heart and genuinely cares about others, even if she can't express that correctly and doesn't even hide the fact that she can't understand emotions. Doma, on the other hand, is a cheerful and energetic demon, who seems to always keep a smile on his face and rarely gets upset at times. However, this is proven to be nothing more than a fake demeanor Doma created in order to hide his lack of emotions, something Kanao rightfully calls him out for, with his true personality being a deranged nihilistic sociopath.
Earn Your Happy Ending: After every hell Kanao was put in through, especially losing her sisters, Kanao finally gets the ending she rightfully deserves, as she's among the survivors of the Final Battle and now gets to live her entire life with the man she ultimately loves.
Forced to Watch: Kanao is unable to do anything to save Shinobu from Doma, who's slowly absorbing her in his body.
Friend to All Living Things: Kanao seems to have a fondness for nature and animals, and is often seen with a butterfly gently perched on her finger. It is for this reason that Sanemi gave her the deceased Obanai's pet snake Kaburamaru to care for after the final battle.
Good Is Not Soft: She's a pleasant and friendly girl despite her quietness, and she doesn't hesitate to slay any demon.
Hand Wave: Kanao’s skirt gets visibly shorter as the series goes, it started with being below her knees, it ended a little above her knees, Gotouge of course tried to make a humorous explanation on why that happened, simply stating the resident perverted Corps tailor, Masao, has been secretly making changes to Kanao’s uniform since he can’t fool any other female slayer into wearing what Mitsuri got anymore.
Heads or Tails?: Up until meeting Tanjiro, she makes decisions by flipping a coin if she is not given instructions on what to do.
Happily Married: She eventually becomes the wife of Tanjiro Kamado. And while we don't really see much of their life together, many can tell that they had a happy life together.
Heroic Sacrifice: Kanao uses the final form of Flower Breathing: Equinoctial Vermilion Eye in her remaining left eye to avoid Tanjiro's attacks and inject the antidote to turn him human again. She succeeds in injecting Tanjiro with the antidote at the cost of getting stabbed through the chest. Fortunately, she makes it out alive.
Hidden Depths: Volume 19's Taisho Rumors reveal that Kanao took the Demon Slayers' Selection Exam by her own volition and without permission from either Kocho sisters back in her very first appearance in the manga, showing that she had a bit of a rebellious streak even way back then and before Tanjiro helped get her further out of the comfort zone she made for herself.
I Just Want to Have Friends: During her Day in the Limelight in the anime, she is shown to be watching Tanjiro, Zenitsu, and Inosuke train to master Total Concentration Breathing at a distance. When Shinobu nudges her to join in, she just flips her coin and walks away, looking disappointed in the result. During the fight with Doma, it's shown that even with the little contact they've had, she considers Tanjiro, Zenitsu, Inosuke, and Genya as her dear friends.
Important Hair Accessory: She wears a butterfly-shaped hairclip to hold up her side ponytail. It originally belonged to Kanae Kocho before she died, and Kanao wears it as a Tragic Keepsake. During her fight with Doma, it gets broken and she later replaces it with Shinobu's butterfly hairclip after Shinobu's own death at Doma's hands.
Instant Expert: According to Volume 19's Taisho Rumors, Kanao learned and eventually mastered Flower Breathing just by watching Kanae and Shinobu from afar.
It's Personal: Kanao doesn't have anything against demons, only slaying them because it is expected of her as Shinobu's successor. However, her fight against Upper-2 Doma is the first time where she truly has something at stake, due to the demon-killing Shinobu right in front of her and having killed her other sister figure Kanae in the past. Kanao comments that this is the first time in her life she felt a strong hatred for anybody.
Jerkass to One: Kanao, despite being a quiet person is usually a Nice Girl when it comes to her friends and loved ones, especially to Tanjiro and Shinobu. But when it comes to the Upper-2 demon, Doma, she suddenly becomes fuel by hatred and spite of him, throwing endless insults at him. This is heavily understandable considering the man is responsible for killing Kanae and Shinobu.
Lady of War: A quietly graceful young girl and user of the Flower Breathing, a style which focuses on graceful sword flurries and spins. She is noted to be even stronger than her adoptive older sister Shinobu, the Insect Hashira.
Legacy Character: She becomes a practitioner of Flower Breathing, just like her late oldest adoptive sister, Kanae.
Love Interest: She becomes one for Tanjiro, after the time they spend together during the Rehabilitation Training and because Tanjiro helped her in developing more emotions and encouraging her to make choices for herself. In the end, the two would be happily married with each other and be blessed with a family of their own.
Made a Slave: Her parents sold her into slavery, presumably because they were so dirt poor they would do anything for money. Luckily, she was freed by Shinobu and her sister not long after she was sold.
Massive Numbered Siblings: The second Databook shows that Kanao’s biological family tree was huge, her abusive parents had eleven children including Kanao, a terribly large number of offsprings for such horrible parents who beat some of them to death, literally.
The Medic: The special illustrations and accompanying info in the second Fanbook shows that after Muzan and the Demon Slayer Corps are done, Kanao devoted herself to the more clinical aspect of the Butterfly Estate practices, something that she previously sucked at, which prompted her to become a strong demon slayer before, since she really wanted to be useful.
My Defense Need Not Protect Me Forever:
- This is the crux of her entire plan in the battle against Doma. Kanao knows she can't defeat him in a straight-up fight, and she is also aware of Shinobu's gambit to poison him after being devoured, so she only fights to prolong the battle until the poison kicks in and creates an opening to kill Doma. This plan is fortunately helped along by Inosuke's arrival and Doma's decision to toy around with them instead of fighting seriously.
- Also done in the battle with Demon Tanjiro. Kanao knows she can't beat him, and even Flower Breathing: Equinoctial Vermilion Eye won't allow her to avoid his attacks forever (along with possibly blinding her remaining eye). But all she needs to do is dodge until she gets an opening to inject the last of Tamayo and Shinobu's demon antidote to turn him human again, at which point Tanjiro can come back to his senses on his own.
Never Given a Name: Her abusive parents thought so little of their children that Kanao was never given a name, like all her siblings; when Kanao was properly adopted by the Kocho sisters, she was given the name Kanao Tsuyuri. The extras within Volume 19 reveal it was Kanao herself who came up with her name, choosing through several suggestions of given and family names presented to her.
Nice Girl: Despite her quiet and emotionless nature, Kanao is a very pleasant and kind girl.
Not So Stoic: Kanao is usually a calm girl. But when it comes to Doma, let's just say that Kanao's calm attitude changes big time.
Not Used to Freedom: Kanao was abused by her parents and sold as a slave from a very young age, which turned her into an Emotionless Girl who won't do anything unless told to. Even after she was freed and became a demon slayer, if she receives no orders, she initially relies on a coin toss to make decisions. It takes Tanjiro's intervention for her heart to start opening up again and learn to have more free will.
Official Couple: With Tanjiro.
Out of Focus: Compared to all the other people from Tanjiro's selection, Kanao has the least amount of screen time and interactions. The first time we even see her fight a demon (sans Nezuko) is well after she had been fully introduced. Slightly justified as she's a Tsuguko, and therefore is not in a position where she's often out on the field.
Petal Power: Kanao managed to become a Flower Breathing adept like Kanae, unlike Shinobu, who became an Insect Breathing adept, a direct offshoot from the Flower Breathing.
Pink Means Feminine: Kanao's Nichirin Sword is pink.
Progressively Prettier: Gotouge starts to draw Kanao more mature looking much later in the series, with her possibly going through another puberty spurt. Despite these changes happening in less than a year in-story, Kanao becomes more feminine and with more notable body curves, matching Shinobu in this regard.
Puppy Love: She harbors a very subtle and tender attraction towards Tanjiro, and is always silently joyful of being at his side to the point of childishness. She's like a little girl in love.
The Quiet One: Kanao has communication problems and is somewhat absentminded, so she sometimes creates problems and extra work for the people that work at the Butterfly Mansion because she's just too quiet. Though thankfully, she slowly starts to grow out of it, even if it's slightly.
Rags to Riches: Kanao came from an extremely poor and abusive family; her parents literally threw her out and sold her off as a slave. However, she got rescued by Kanae Kocho and Shinobu Kocho before Kanao’s life as a slave could actually begin. The Kocho sisters came from a well off family, and even after being orphaned, they became Demon Slayers under the very wealthy Ubuyashiki estate. Under Ubuyashiki, the Kocho Mansion was kept well maintained by their earnings from demon slaying; Kanao is registered as the youngest sister of both Kocho girls, enjoying a resourceful life as a member of the Kocho family.
Rank Up: Kanao starts her career as a Demon Slayer as the lowest 10th rank, Mizunoto, she rises quickly however, being a Tsuchinoto by the Natagumo Mountain arc, 6th rank; the Infinity Castle arc starts with her as Hinoto, 4th rank, four steps away from becoming Hashira, oddly ending one rank less than Tanjiro and his companions despite her quick early growth; which is only revealed in the 2nd Databook.
"The Reason You Suck" Speech: Delivers a brutal and sadistic speech towards Doma after his "mourning" over the death of Akaza, telling him that she's able to see through his faked emotions because he actually can't feel anything from joy to sadness, (while other people can) and wonder about the reason for his existence, all while smiling sadistically. This actually manages to piss off Doma, who immediately drops his fake cheerful nature and suddenly gets all more serious on killing her.
Revenge: Alongside Shinobu, this was one of her main goals of being a Demon Slayer: To have the chance to kill Doma, the demon responsible for her eldest sister's death. Her vengeance against him is fueled further when Doma devours Shinobu, right in front of her.
Sadist: Oh boy, and a HUGE ONE when it comes to Doma. She takes great pleasure in calling out Doma for his lack of emotions and faking them, all while questioning his existence. She even gives out a chilling sadistic smile as she taunts Doma.
"Why were you even born?"
Ship Tease:
- A flashback has Kanae stating that Kanao can change if she can find a guy she likes. An image of Tanjiro is shown when she remembers this.
- The final chapter, taking place in modern day Japan, opens featuring two siblings (Kanata and Sumihiko) who look like fullblown Generation Xeroxes of Kanao and Tanjiro respectively. This implies that the two ultimately ended up starting a family together.
Slipknot Ponytail: When Doma launches a bigger attack against Inosuke and Kanao, it breaks her hairpin apart and undoes her ponytail.
Socially Awkward Hero: Due to her tragic past, Kanao has a hard time talking to people and often relies on her coin to see if she should engage in a conversation or not. However, thanks to Tanjiro's influence, she begins to grow out of this, being capable of socializing with people a bit more normally.
The Stoic: Downplayed. Kanao can show emotions, but due to her troubled past, she really can't express them correctly. However, thanks to her time with the Kocho sisters and later on, Tanjiro, she begins to express her emotions more clearly and freely.
Super-Senses: Her eyesight is supernaturally good, able to pick out even the most subtle changes on a person's face. Exaggerated by her ultimate technique, Equinoctial Vermilion Eye.
Superior Successor: When fighting her, Doma realizes that Kanao is actually stronger than her Hashira sister, Shinobu.
Tears of Joy: Kanao had two special moments where she cries with pure joy in her eyes.
- The first is when Tanjiro finally awakens from his coma, following his battle with the Upper Six Kizuki Demon in the Entertainment District. She tearfully smiles with great relief that Tanjiro has finally awaken from his coma after two months had passed.
- The second is when Tanjiro finally returns to being a human after being cured, Kanao cries with happiness, relieved that Tanjiro has returned to being a human.
Tragic Keepsake: Her butterfly hairpin was previously Kanae's before she was killed by Doma. The tragedy is doubled when Shinobu herself dies, and Kanao's hairpin is destroyed in the fight against Doma. Kanao gets Shinobu's hairpin from that event after Doma is killed.
Tranquil Fury: Kanao manages to keep her rage in check when fighting against Doma. But that doesn't stop from throwing endless insults at him, all while being heavily sadistic about it.
Unable to Cry: Chapter 163 reveals that Kanao was unable to cry because of her harsh childhood, which troubled her greatly when she was unable to cry over Kanae's death. But after encouragement from the spirits of Kanae and Shinobu, she is finally able to cry and express her emotions. The next chapter, 164, shows both Kanao and Inosuke letting their tears run after a long and emotional battle.
Wrecked Weapon: Her sword is destroyed by Muzan in the final battle.

Murata

Voiced by: Kōki Miyata (Japanese), Khoi Dao (English)^{Other VA}

One of the Demon Slayers middle ranks and a friend of Tanjiro.

Action Survivor: Apart from being one of the survivors of the Mountain battle, he also manages to survive the assault against Muzan and the Upper Ranks.
Berserk Button: He gets rather cross whenever someone he outranks doesn't respect him, whether Inosuke in the Mount Natagumo arc or a disguised Yushiro (who is not actually a Demon Slayer) in the final arc.
Butt-Monkey: He always ends up in situations that are troublesome like getting his clothes melted off by the spider demons, being mocked by Yushiro while fighting some of Muzan's demons, and getting his hair pulled by an injured Zenitsu who is freaking out about the castle collapsing in chapter 183.
Clark Kent Outfit: Upon Murata experiencing Clothing Damage from spider demons, we learn that he's surprisingly muscular.
Making a Splash: Murata utilizes Water Breathing, but isn't at Tanjiro or Giyu's level of proficiency at it as he lacks the water visuals they have and his Nichirin Blade's color is plain.
Mauve Shirt: He's just a regular member of the Demon Slayer Corps, and while he does get more screentime than others of his rank, he still remains a minor character.
Nice Guy: He's a very kind young man and easily befriends Tanjiro and the other heroes. He even compliments Tanjiro's cooking skills during their training with Himejima and shows great concern and care for an injured Zenitsu.
Older Than They Look: It can be easy to assume he's within the same age range as Tanjiro's group due to his appearance and behavior, but he is actually closer in age to Giyu, as it's revealed that they both took part in the same Final Selection.
Ridiculously Average Guy: He managed to survive Demon Slayer training, but his strength in battle is quite average in comparison to the others. In the battle against Muzan, Murata has a hard time trying to attack the neck of a rather big demon. It's revealed in Volume 17's extras that he's a Water Breathing user, but Murata is seemly so weak that his moves don't even produce the visual effects for water like Tanjiro's and Giyu's do.
Running Gag: Murata becomes enraged when he assumes a fellow demon slayer is ordering him around or talking back to him. Murata immediately yells at the supposed disrespectful fellow and asks for their rank, implying that he will only accept orders from a slayer who ranks above him; with Tanjiro & friends, however, Murata mellows out as he sees how really helpful they are in the Nagatumo Mountain event. Murata grows to admire them and see them as friends.
Suddenly Shouting: Upon hearing Yushiro's analysis of Zenitsu's condition, he yells at him to stop being so negative towards Zenitsu and even tries to cheer up Zentisu by encouraging him to survive. All of his yelling, along with the other rookies, ends up attracting the attention of Muzan's demons.

Genya Shinazugawa

Voiced by: Nobuhiko Okamoto (Japanese), Zeno Robinson, Alan Lee (child) (English)^{Other VA}

^{Click here to see his special form (Spoiler).}

"I'll do it. I'm gonna do it. I have to do it. Think about only winning. I will not let my brother, or my master, or any of my comrades!"

A Demon Slayer who took and passed the same entrance exam as Tanjiro. He is also the younger brother of the Wind Hashira, Sanemi Shinazugawa. Unlike his comrades, he in incapable of using breathing styles, but makes up for it by wielding a gun in battle, as well as eating Demon flesh and gaining their powers.

Actor Allusion: Upon meeting Tanjiro in the Swordsmith Village, he lets out an angry "SHI NE!" (meaning "die" in Japanese) that sounds very similar to Bakugo's Catchphrase Insult, whom Nobuhiko Okamoto also voices.
Adaptation Dye-Job: Gotouge isn’t consistent with giving Genya the color gradient effect. He has sometimes been drawn with yellow hair tips, but he has also been drawn with just full black hair as well. The anime followed on giving him full black hair. Until the animated adaptation of the Swordsmith Village reconciled this by making Genya’s new yellow hair highlights part of his demon transformation.
Advertised Extra: Genya is featured in the first opening despite having only one speaking appearance and silent cameo to his name in Season 1.
Arc Hero: He, alongside Muichiro Tokito and Mitsuri Kanroji, serves as one of the main characters of the Swordsmith Village Arc.
An Arm and a Leg: In an attempt to save Muichiro, he gets both of his arms cut off and his torso bisected by Kokushibo before being saved by his brother Sanemi. He gets put back together by eating a piece of Kokushibo's hair with the help of Muichiro.
Big Brother Instinct: Genya's brotherly instincts have returned after entering into puberty and after the Swordsmith Village Arc. In chapter 4 of the second light novel, Genya stops an angry Demon Slayer member from harming the girls at the Butterfly Estate while in an enraged state. He single-handedly catches a vase that is thrown by the member and manages to convince him to calm down.
Big Little Brother: Reaching puberty or more accurately eating demons has done wonders to Genya, like making him rival his brother Sanemi in height.
Blood Knight: Just like his big brother, Genya can be heavily eager and thrill on fighting demons, as best seen during his fight against Hantengu and his clones.
Cannot Talk to Women: Genya is shown nervously blushing when Mitsuri hugs everyone after surviving the battle at the swordsmith village in chapter 127. Even prior to that, he refused to talk to Mitsuri when both happened to bathe at the hot springs, mainly out of shyness. On the cover page of chapter 129, Genya is shown blushing and politely declining to be fed by the Butterfly Estate girls. This is probably due to him reaching puberty, where he views girls with much more respect, as seen in the extra chapter of 133, where he apologizes to Ubuyashiki's daughter for pulling on her hair, with her happily forgiving him.
Cannibalism Superpower: Genya can take on the Blood Demon Arts of demons with huge saturations of Muzan's blood such as the Upper Ranks. The Demon Blood Art he used against Kokushibo takes elements of Hantengu's Hate emotion's ability to grow trees and Kokushibo himself's ability to convert his own flesh into living weaponry.
Character Development: In the beginning, Genya was a short-tempered, rude, and violet person, who attacked both his crow and Kanata due to his impatience of wanting his sword and was more of a lone wolf. Even now, he was still incredibly rude as he ignored Tanjiro and his kindness, even viewing him as a rival for the Hashira position. Eventually, during the Swordsmith Village Arc, he learned how to be more cooperative with Tanjiro and Nezuko during their battle against Hantengu, and in the following chapters, has grown more friendly and kind, no longer the short-tempered and violet person he was in the past.
Covered in Scars: He's covered in scars, which makes him look quite scary and brutal most of the time. The ones on his face are from his mother-turned-demon, the day she killed the rest of his siblings.
Delinquent Hair: His wild mohawk gets quite impressive since Tanjiro first meets him. It goes well with his authority-defying, impatient attitude.
Died in Your Arms Tonight: After sustaining fatal injuries in the battle against Kokushibo, he lives long enough to reconcile with his brother Sanemi and crumbles away in his arms.
DIY Dentistry: He pulls one of his teeth out. Just a couple hours later, it has miraculously grown back.
Dramatically Missing the Point: Genya insisted on becoming a Demon Slayer against his brother's wishes, unaware of the fact that his brother himself joined and even rose to become a Hashira in order to provide him with a peaceful life.
Easily Forgiven: In the Swordsmith Village Arc, Tanjiro always goes on trying to befriend Genya, despite his actions at the end of the Final Selection, showing that Tanjiro didn't hold a grudge on him for how he treated Kanata. Interestingly, in the extra chapter of 123, he apologizes to Kanata for how he treated her in the past, with Kanata happily forgiving him for it.
Eating the Enemy: He's capable of eating demon flesh to temporary gain some of the resilience and strength of demons, something that's noted that not everyone can do. This pisses off his brother very much when he finds out, to the point where Tanjiro had to intervene to save Genya. This ability also has healing capabilities, as seen in chapter 171, where he eats a piece of Kokushibo's hair to heal his body. On top of that, it also grants him power copying capabilities, where he can temporarily use the powers of the demon he consumes, like parts from Hantengu and Kokushibo (specifically his broken blade).
Eye Scream: Is nearly subjected to this in chapter 133, where once he lets it slip to Sanemi that he's been eating demons, the latter rushes at him at lightning speed and attempts to jab his fingers into his eyes. Luckily, Tanjiro pushes Genya out of the way a split second earlier.
Face of a Thug: His facial scars make him look like someone you wouldn't try to get friendly with, but as the series progresses, he becomes a nicer person in spite of his appearance.
Fire-Forged Friends: When Genya is reintroduced, he develops an intense grudge toward Tanjiro for breaking his arm even though the latter makes numerous attempts to befriend him at the Swordsmith Village arc to no avail. It's only when both boys are forced to team up against Hantengu that Genya mellows down and has a positive relationship with Tanjiro.
Foil:
- To Nezuko. Both were the second oldest siblings of their families and were the only other survivor of them aside from their older brothers following a demon attack. However, Genya cannot use Breathings but has the unusual ability to gain the power of a demon from eating their flesh while Nezuko is an unusually powerful demon able to recover from only sleeping. Also, their older brothers act very differently toward them (Sanemi is abrasive and rude while Tanjiro is kind and gentle) but ultimately both care deeply about their younger siblings.
- Also to Inosuke, to a certain extent. Both are short tempered, angry members of the Corps, but are almost polar opposites of each other. After completing the final selection test, Genya is so impatient that he attacks Ubuyashiki's daughter, whereas Inosuke was so impatient that he left. They both encounter Tanjiro after attacking an innocent and get their bones broken by him as a result, but their reactions are completely different: Genya attacks Ubuyashiki's daughter and Tanjiro breaks his arm, making Genya hate him and refuse to talk to him, until they eventually become friends in a later arc. Inosuke, on the other hand, brutally beats up Zenitsu and Tanjiro breaks his ribs in order to stop him. Inosuke is impressed by his opponent and starts fighting back, laughing and giving him a rather tough fight, and instead of avoiding him like Genya, he keeps trying to provoke Tanjiro to fight him again. Genya also doesn't wield swords, while Inosuke is a dual wielder. Genya also cannot use Breathing techniques, whereas Inosuke invented his own Beast Breathing technique. Appearance wise, Genya is covered in scars that make him look rather scary. Inosuke, on the other hand appears scary because of his Boar mask and is actually very pretty underneath it.
- And also to Senjuro. Both are the "talentless" younger brothers of highly skilled Hashiras who endured abusive fathers (though Kyogo was far worse than Shinjuro). They both love their brothers immensely as well. Outwardly, these relationships are day-and-night. Kyojuro and Senjuro have a very warm, loving bond despite their misfortune. Meanwhile, Genya and Sanemi have been driven apart due to Sanemi killing their mother, and Sanemi treats Genya coldly. But this is a farce. Sanemi loves Genya just as much as Genya loves him. One of the key differences between them, personalities aside, is that Genya actually managed to become a demon slayer. He could only do this by using a gun instead of a sword and eating a demon. Senjuro, on the other hand, accepted that it wasn't meant to be.
Foreshadowing: Tanjiro catches Genya removing one of his canines, only to find him later having miraculously grown a new tooth in its place. This is the first hint Genya possesses the ability to temporarily become a demon and gain their powers.
Friendship Denial: In the Swordsmith Village arc, Genya keeps pushing Tanjiro away and saying they're not friends because he still holds a grudge over Tanjiro breaking his arm at the Final Selection. He later mellows out a bit after they fight together and he starts to respect him.
Ghost Memory: When Genya eats demons that have a large saturation of Muzan's blood, he can hear Muzan's voice and conversations with the demon that he ate.
Good Old Fisticuffs: Apart from his Demon Art and his gun, Genya is one of the few Demon Slayers that doesn't employ a sword in combat in spite of being issued one after his selection. Thus, he also employs hand-to-hand combat.
Green Thumb: Genya's Blood Demon Art manifests as living bullet seeds that grow into trees and immobilize their opponent by drinking their blood.
Hair-Trigger Temper: At first. He does mellow out after the incident with the swordsmith village, though there are moments where he will still get mad, such as when Zenitsu is trying to help him escape Sanemi's wrath and calls Sanemi inhuman, which causes Genya to punch Zenitsu even though they're on the same side. When he tells Tanjiro that he can't use Breathings, Inosuke insults him and calls him a shrimp, causing both Genya and Inosuke to get into a little scuffle.
Half the Man He Used to Be: Twice, courtesy of Kokushibo. The first time is when Kokushibo defeats Muichiro, and Genya attempts to help out by shooting him, getting his body and limbs sliced horizontally for his trouble. The second time is during Kokushibo's Desperation Attack, this time being sliced vertically. This one proves fatal.
Hot-Blooded: He's very aggressive like many other characters voiced by Nobuhiko Okamoto.
I Got Bigger: When Tanjiro first sees him again after the Final Selection arc, he's gotten much taller and more imposing, which also implies that Genya is going through puberty, and to hint that he was eating demons to enhance his abilities.
I Hate Past Me: He thoroughly regrets his violent, reactionary past-self, especially regretting his behavior during the Demon Hunter exam.
Jerkass Has a Point: When they meet again in the Swordsmith Village Arc, he's initially hostile and aggressive towards Tanjiro, for no reason other than a petty grudge stemming from Tanjiro breaking his arm in retaliation to him assaulting Kanata. That is until Tanjiro reveals he kept a tooth Genya had previously lost in the hotsprings, in which him lashing out was completely warranted.
Jerk with a Heart of Gold: Genya starts the series as a huge jerk that even boy of pure innocence Tanjiro feels forced to discipline by breaking his arm! This is further shown when he goes out of his way to bump into Tanjiro as they pass each other in the Butterfly Mansion. However, during the Swordsmith Village arc, Genya actually starts to open up to Tanjiro and admit why he's trying so hard to be tough. By the end of said arc, his smile at Nezuko defeating the sun, is heartwarming!
Killed Off for Real: Genya is the first of those who survived Tanjiro's selection batch to die, succumbing to his injuries after giving his brother and mentor an opening to take down Kokushibo.
Made of Iron: Eating demons probably raises his body's durability, as shown when he gets his torso and arms cut off by Kokushibo, but still manages to survive before Sanemi jumps in to help.
Must Make Amends: In his backstory, when most of his family were slaughtered by what he thought was a wolf (which was actually his demonized mother), and he found his mother dead at the hands of Sanemi, he called him a monster, which strained their relationship. But after learning the truth behind his mother's death, he becomes regretful of his behavior and wanted to apologize, which is why he joined the Demon Slayer Corps. Unfortunately, Sanemi isn't interested (or so it seems at first). But then they face Kokushibo, thus leading Sanemi to defend Genya when he's attacked. Sadly, they are only able to truly reconcile as Genya dies.
My Greatest Failure: Genya in the past called Sanemi a monster after he killed their mother-turned-demon who already killed the rest of their siblings to save his life. He regrets this even now.
Never My Fault: He refuses to accept Tanjiro broke his arm because he assaulted one of the Ubuyashiki girls because they didn't give him a Nichirin blade immediately as he demanded. However, when he mellows out later on, he reconsiders his actions and apologizes for his harsh behavior.
Nice Guy: Back in the past, young Genya was a loving and kind person, who provided support and care for his family. He eventually returns on being the kind and caring person he was in the past, mainly thanks to Tanjiro's influence.
No Body Left Behind: Genya fades away into dust as he dies, much like a demon because he took in a huge amount of Muzan's blood in his final moments. His clothes are the only things that remain after Genya fully dissipates.
Polite Villains, Rude Heroes: He's the rude hero to Aizetsu's polite villain.
Perpetual Frowner: He's normally seen with scrowl on his face. It isn't until he Took a Level in Kindness that starts smiling more.
Pulling Themselves Together: With Muichiro's help, Genya manages to reattach his body parts together again by eating Kokushibo's hair, which helps instantly heal Genya.
Rank Up: Genya starts his career as a Demon Slayer as the lowest 10th rank, Mizunoto, the series doesn't touch up on his progress after that; he died as a Hinoto, 4th rank, four steps away from becoming Hashira, which is only revealed in the 2nd Databook.
Scars Are Forever: Genya acquired his facial scars when his mother turned into a demon and attacked his family in his childhood. They're still there after he grew up.
Sour Outside, Sad Inside: His angry demeanor hides a boy who's regretful of the wedge between himself and his brother Sanemi and the cruel words he said to him after Sanemi was forced to kill their mother-turned-demon.
Speak Ill of the Dead: He unsurprisingly badmouths his abusive father, and remarks at his murder with satisfaction, claiming it was deserved.
Sword and Gun: The only Demon Slayer to wield a gun, due to being unable to use Breaths. It shoots specialized bullets made of the same material that Nichirin Swords are made of.
Took a Level in Kindness: Still a little bit rough, but he greatly mellows out after the swordsmith village incident and is able to get along with Tanjiro and everyone quite well afterward.
Uncertain Doom: After he is sliced in half vertically by Kokushibo, it's unclear for some chapters whether he can regenerate half of his head or not. Later it's made clear that he can't, and he only gets a a few moments to speak with his brother before passing away.
Unknown Rival: A lot of Genya's animosity with Tanjiro was due to him seeing Tanjiro as a rival to getting to the Hashira position, going as far as to loudly proclaim he was going to kill the Upper 4 Kizuki to outdo Tanjiro. Tanjiro however, didn't really understand and just declared his intention to help Genya succeed instead with "Eye of pure innocence". In any other Shonen, Genya would've been the "Sasuke, Vegeta, and Bakugo" to Tanjiro's "Naruto, Goku, and Deku" but he's smart enough to realize Tanjiro is the noncompetitive type. Needless to say, it killed the mood and Genya just dropped it and cooperated with Tanjiro instead of keeping the one-sided rivalry up.
Used to Be a Sweet Kid: Genya was a loving and protective brother in his childhood, always protecting his younger siblings, providing support and care to his mother, and admiring his big brother Sanemi very much. But things changed when the demons attacked their village and Genya grew up bitter and sad. However, all of his times bonding with Tanjiro bring back his loving personality and he's able to reconcile with Sanemi again.
Visual Development: His appearance in his debut and his later appearance when he bumps into Tanjiro in the Butterfly Mansion look vastly different. His boyish features are toned down, and his mohawk is longer and spikier.
When He Smiles: He smiles when he sees Nezuko alive and well in the sunlight along with Tanjiro at the end of the swordsmith village arc. He gives genuine smiles more often in later chapters.

Ozaki

Voiced by: Hisako Tōjō (Japanese), Dorothy Elias-Fahn (English)^{Other VA}

A Demon Slayer and part of the Demon Slayer Corps.

All There in the Manual: Her name is only revealed in the Volume extras.
Broken Tears: She does this when she's forced to kill her comrades against her will and break her bones by the Mother Spider Demon.
Hope Spot: It seems she was saved once Tanjiro had her by getting struck in a tree by no longer controlled by the demon. Unfortunately for Ozaki, the demon had used the remaining thread to her killed. She was a few moments away before Tanjiro could cut off the thread.
Neck Snap: This happened during the Demon’s tantrum for being unable to use “her puppet” and it killed off the remaining puppet by twisting and breaking their necks.
People Puppets: she was unfortunately victim of being one Mother Spider Demon’s puppets. Since she was forced to kill her own fellow Demon Slayer corps members and it doesn’t help the situation the look is of a painful scream and break when she was forced to fight Tanjiro.
We Hardly Knew Ye: She's killed shortly after being introduced by the Mother Spider Demon twisting and breaking her neck.
Yank the Dog's Chain: She was sent mission only to be controlled by Mother Demon Spider as a living puppet that would cause her to kill the other fellow members of Demon Slayer and was forced to fight the Tanjiro. It seemed she was about to be saved. Only to be cruelly killed off by the same demon by twisting and breaking her neck.
You Have Outlived Your Usefulness: This is how Mother Spider Demon viewed it since she got struck by a tree. This causes the demon to kill off her useless puppet.

Confident Corps Member

Voiced by: Taito Ban (Japanese), Kirk Thornton (English)

https://static.tvtropes.org/pmwiki/pub/images/cocky_demon_slayer_1_2.png

An arrogant Demon Slayer who became part of the Demon Slayer Corps solely to rise through the ranks and get more money. He barges in on Tanjiro and Rui's confrontation and gets himself killed when he arrogantly tries to take on the latter.

Asshole Victim: Considering that he cares nothing for the lives of his fellow Demon Slayers and only for money, you're not likely going to feel sympathy for him when he gets killed by Rui.
Boisterous Weakling: Granted, he is a Demon Slayer who must have survived the Final Selection, so it would be inaccurate to call him a weakling. But he still tries to bite off more than he can chew when he tries to kill Rui under the assumption that a kid-like demon will be easy pickings. This arrogance gets him killed.
Cruel and Unusual Death: Gets the top half of his body diced to pieces by Rui's razor-sharp webbing.
Deliberately Bad Example: Other than getting himself killed to show that Rui is more dangerous than he looks, this guy's only purpose in the story is to be a bad example of how a Demon Slayer is supposed to be, since he only prioritizes personal gain over actually saving lives. Every honorable demon slayer puts their life on the line to save people from the demons without prioritizing personal gain. He pretty much gets an Undignified Death for his troubles without his name or backstory being revealed, and since he has no one to mourn his death, he is pretty much treated as an afterthought.
Lack of Empathy: He is completely unconcerned about the deaths of his fellow Demon Slayers so long as he can climb through the ranks and earn a bigger paycheck.
No Name Given: He never has his name revealed before he's killed by Rui. Even the databooks don't mention his name.
Only in It for the Money: He seeks to climb the ranks and earn a bigger paycheck, and that's his sole reason for becoming a Demon Slayer.
Smug Smiler: The only expression this guy has during his only appearance is an arrogant smile.
Too Dumb to Live: He walks in on Tanjiro and Rui's confrontation, boasts that he can kill a kid-like demon easily, and refuses to listen to Tanjiro's warnings about Rui. Rui simply dices the top half of his body to pieces without even bothering to look in his direction. Even if this Demon Slayer had no way of knowing that Rui is one of the Twelve Kizuki, charging at an unknown enemy just because he doesn't look strong to you is a surefire way to getting yourself killed.
Undignified Death: After arrogantly boasting that he can kill Rui easily due to his child-like appearance, Rui simply dices him to pieces without even bothering to look in his direction as soon as he attempts to charge at him. His death is quickly treated as an afterthought, and he is forgotten by everyone present.
Underestimating Badassery: He believes that since Rui is a kid, he should be easy for him to kill. He refuses to listen to Tanjiro's warnings that Rui is more dangerous than he appears, and as a result he gets killed by Rui as soon as he charges into battle without the demon even bothering to look in his direction.
We Hardly Knew Ye: He's killed shortly after being introduced by Rui dicing the top half of his body to pieces.
Wrong Assumption: When he sees Rui, he immediately assumes that a kid-like demon will be easy for him to kill and refuses to listen to Tanjiro's warnings that Rui is a lot more dangerous than he looks. This arrogance gets him killed when he attempts to charge into battle, with Rui simply dicing the top half of his body without even bothering to look in his direction.

A member of the Demon Slayer Corp who informed Kyojuro Rengoku about finding the whereabouts of the Mugen Train.

Advertised Extra: He appeared in the trailer to make one believe he is partnering with Kyojuro Rengoku for the mission. However, he leaves early to deliver bento boxes for other Corp members by Kyojuro. He only appeared near the end of episode.
Canon Foreigner: He didn’t appear in manga. He used to help Kyojuro Rengoku with the information about Mugen Train, and updates on injured women from previous demon attacks.
Don't Celebrate Just Yet: Once Kyojuro Rengoku informs that he killed the Slasher demon. He thought the mission on the Mugen Train had concluded. Unfortunately, the Slasher demon isn’t the main cause for the disappearance of the train.
Innocent Blue Eyes: He has bright blue eyes.
No Name Given: He isn't even given proper specification in the credits, let alone a name.

Masachika Kumeno

A Demon Slayer who introduced the Wind Hashira, Sanemi Shinazugawa, to the Demon Slayer Corps. He and Sanemi developed a close friendship with one another and competed for a position of the Wind Hashira until he died in a confrontation with Ubume, the Lower Rank 1 of the time.

Annoying Younger Sibling: A non-blood-related example; he frequently refers to Sanemi as his aniki (roughly an equivalent to calling someone "bro") and treats him as his brother due to them both training under the same trainer. He also frequently nags Sanemi to take care of himself and not be reckless while also interacting with him in a very informal and overly-friendly manner, much to Sanemi's irritation.
Ascended Extra: Originally appearing as a flashback extra in Chapter 168, he was given much more prominence in the "Signs from the Wind" spin-off light novel that greatly expands on his characterization, highlighting his kindhearted personality and bond with Sanemi.
Beware the Nice Ones: While he's overall a pleasant and friendly guy, he has his limits regarding how much empathy he can show before the threshold is crossed and he deems someone to be Beyond Redemption. When Ubume crossed that threshold after his discovery that, even back when she was a human, she tortured her own child for the sake of "nursing" her for her own self-satisfaction, and then killed her when she rebelled, he reacted with genuine rage and disgust and became determined to help Sanemi kill Ubume. Furthermore, as Sanemi had guessed, deep inside, Masachika is also driven by a hatred for demons which he masks underneath a thick layer of cheerfulness.
Dead Partner: He was Sanemi's partner who took part on a mission that got Sanemi promoted to a Hashira. However, he was killed by Ubume, which made Sanemi suffer from a guilt of losing one more person who became close to him.
Friendly Rivalry: He treated Sanemi as a friendly rival, willing to compete with him on who becomes a Hashira first, jabbing that a loser will buy a winner a lunch. In the end, Sanemi was the one to become a Hashira while Masachika was killed by Ubume.
Nice Guy: As shown in "Signs from the Wind" spin-off novel, he was a very kind and compassionate person, always showing concern for Sanemi and the others and encouraging the former to live his life to his fullest.
Posthumous Character: He died before the events of the series took place, killed by Ubume, the Lower Rank 1 of the time.
Stepford Smiler: As Sanemi eventually learns, Masachika, despite coping with it differently, is also driven by hatred for demons, with his cheery behavior being a coping mechanism to help him move forward in life after his younger brother's death.

The Founder of Breathing Techniques (Spoilers)

Yoriichi Tsugikuni

Voiced by: Kazuhiko Inoue (Japanese), Mick Lauer (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/kny_yoriichi_anime.jpg

^{Click here to see his last stand}

"Why do you steal peoples’ lives? Why do you ruin them? What is it that makes life interesting? What do you think life is? Don’t you see? How could you forget?"

The figure of legend who almost killed Muzan Kibutsuji 400 years in the past. He was a Demon Slayer whose skills seemed to be divine, earning some envy from people due to how unreachable Yoriichi seemed to be, namely Shinjuro Rengoku in the present and his own older twin brother in the past, Michikatsu Tsugikuni, later known as Kokushibo.

Yoriichi was the creator of the foundation of all Breathing teachings, later labeled as Sun Breathing. His special body condition with affinity towards its techniques made Yoriichi the first Demon Slayer to have capabilities beyond human perception, and with that he taught others what he could do, albeit none at the time could fully replicate him, thus all other Breathing styles were born.

He is technically the reason for the establishment of the Hashira rankings since it is revealed that the hierarchy within the Demon Slayer Corps was put into place thanks to Yoriichi demonstrating the power gaps between the Slayers.

Accidental Hero: Yoriichi never tried to tutor Sumiyoshi on Sun Breathing intentionally. During their time together, Yoriichi felt like a worthless person; he only showed all his Sun Breathing techniques to the Kamado's ancestors solely on Suyako's request because she found his techniques pretty to look at, so every time Yoriichi visited them Suyako would ask him to display his art. Sumiyoshi, however, felt that Yoriichi wasn't worthless at all: he believed that he was their hero and that he deserved to leave a legacy behind. Thus, Sumiyoshi would use his extreme photographic memory to systematically learn everything Yoriichi could do by just looking at him perform Sun Breathing to them. Yoriichi left Sumiyoshi's family hoping they would live a honest good life with his cherished Hanafuda Earrings to ward evil away and the house that once belonged to him and Uta. He was completely unaware that a secret Sun Breathing legacy was left all the way up to Tanjiro Kamado, to potentially end what he started: the quest for Muzan's death.
All-Loving Hero: Though Yoriichi had a hard time expressing it, he held all human life to be sacred. He was often willing to put his own life on the line in order to help other people and even became a Demon Slayer to prevent Muzan and his demons from destroying innocent lives. Destroying that sanctity was a good way to earn Yoriichi's ire. He didn't see all demons as evil things that he needed to kill though. Right after he fought Muzan, Yoriichi noticed Tamayo was not a threat and managed to console her when she was crying due to Muzan's escape.
Ambiguous Situation:
- The story behind the sword inside Yoriichi Type Zero is not made entirely clear in the series proper, the design of the handle, hilt and blade differ slightly from the sword Yoriichi uses throughout all his appearances, however, the blade is definitely meant for Sun Breathing users since Tanjiro felt it fit him perfectly, and the blade has the "Metsu" engraving that only Yoriichi's blade had, also Haganezuka remarks how amazing the blade is even in its aged state; thus that mysterious blade that is reforged as Tanjiro's final sword is either Yoriichi's sword recycled into a different base hundreds of years ago, or a new sword once meant for Yoriichi but was left as a lingering hope for a future Sun Breathing user instead.
- The narrative never actually gives Yoriichi his official role within the Demon Slayer Corps, He walked among the Hashira of his era like they were his peers but oddly, Yoriichi himself is never referred to as a Hashira. Not even the Databooks bother to further explain that, Yoriichi is always officially referred to as just a demon slayer with no rank attached to his name despite his immeasurable importance at the time for the Corps. Only one curious trivia is mentioned through Goto, the Kakushi Brigade member, that Yoriichi inspired the creation of the Hashira rank, without ever getting into additional details afterwards, as if this seemly crucial piece of information didn't warrant any further explanation. Even when he got expelled from the Corps after failing to kill Muzan warranted a mention of his rank being disgraced; Yoriichi is consistently left without a rank attached to his name in all official sources.
Animal Lover: Yoriichi's unearthly presence always seemed to attract wild animals, a volume extra shows that when he was a kid large group of animals always gathered around him to be pet and fed by Yoriichi.
Arch-Enemy:
- To Muzan, full stop. Even after 400 years, the Demon King is still scarred by Yoriichi's nearly successful attempt on his life.
- He's also this to Muzan's Dragon, Kokushibo, who just so happens to be his older twin brother, Michikatsu. It was the latter's jealousy of his power that led him down the path to abandoning his family for strength, ultimately betraying the Demon Slayer Corps to become Muzan's Number Two. Yorichii could only respond with sadness as he finds out many years later, forcing himself to fight him close to his final moments.
Armor-Piercing Question: He gave a series of these to Muzan during their encounter as seen in Muzan's memories through Daki's eyes.
Yoriichi: What do you find so entertaining? What's so amusing about this? What do you take life for, exactly? How can you forget?
Asskicking Leads to Leadership: Yoriichi singlehandedly inspired the Demon Slayer Corps to instill a hierarchy system, thanks to his absurd skills being so far above anyone in his time. The Hashira ranks were put into place thanks to him after his sword was given the unique "Metsu" (Destroy) engraving in its blade. After that, all Hashira swords were to have "Akkimesatsu" (Destroyer of Demons) engraved in the blades.
Awesomeness by Analysis: Due being born with the Demon Slayer Mark, and all abilities that one can awaken after it, Yoriichi saw the world through a different lens than everyone else around him from birth; when he was 7 years old he could fine tune his X-Ray vision, the Transparent World, to first perceive his mother was secretly sickly before the rest of his family could know, could accurately pin-point the perfect places to strike with a wooden sword despite never being formally trained before, only witnessing Michikatsu’s training on occasion. In his prime as a Demon Slayer, Yoriichi used his acute vision to perceive all of Muzan’s weak points to easily defeat him.
Beware the Nice Ones: Yoriichi may have been an extremely kind and humble person but he was also the World's Best Warrior. Muzan experienced firsthand why you shouldn't anger Yoriichi.
Big Brother Worship: Yoriichi loved and thought very highly of his older twin brother, Michikatsu, because he always treated him kindly in their childhood despite being the privileged heir of their family in contrast to Yoriichi's status as an unwanted child. Even after Michikatsu chose to become the demon, Kokushibo, Yoriichi reflected to Sumiyoshi that his brother was a kind man, and continued to cherish the flute that Michikatsu made for him when they were children. Ironically, Michikatsu also seems to view Yoriichi almost as some sort of god, likening him to "the unequaled sun".
Birthmark of Destiny: Yoriichi was born with a Demon Slayer Mark, something that other powerful characters only awaken in the most life-threatening of situations. The mark also puts incredible strain on the body, but had no negative effects on Yoriichi at all, with him living well into old age despite the mark killing all other users by age 25. The unique nature of Yoriichi's mark is speculated in-universe to have started the spread of the marks to other swordsmen, and his brother believes that it's proof that Yoriichi was "blessed by the gods".
Born Winner: Yoriichi displayed amazing swordsmanship ever since he was young, even when it was his first time holding a sword. His excellence is never properly explained; he was just born that way.
Broken Ace: Yoriichi was the single greatest demon slayer in history. Yet he was haunted by his failure to kill Muzan, his brother becoming a demon and how he could not protect his family from demons, having been a far sadder man than anyone truly knew.
But Now I Must Go: He left Sumiyoshi's home after casually performing all his Sun Breathing techniques on Suyako's request and leaving behind his earrings to continue his fight against Muzan.
Cain and Abel: His relationship with Michikatsu, his older brother, wasn't perfect. Especially when Michikatsu harbored envy towards Yoriichi for his invention of Breathing skills. Michikatsu eventually became a man-eating demon and Muzan's right-hand man.
Child Prodigy: Chapter 177 reveals that Yoriichi was born with the Demon Slayer Mark and that he had improved sight and strength in his everyday life. He learned about swordsmanship from his father's retainer, Ito, very quickly, and swiftly won in their sparring match. He also told Michikatsu that he could see through things, meaning that everything in his vision was transparent to him. He really was a special child in his youth, but he never let that go to his head. Unfortunately, this did make Michikatsu jealous of his talents.
Childhood Friend Romance: Not long after leaving his family's home at age seven, Yoriichi came across a young girl named Uta who had lost her family to disease, and the two became inseparable friends living together as they had no one else. Ten years after meeting, they became a couple and were expecting a child, but it ended tragically as both Uta and their unborn child were killed by a demon shortly before the birth while Yoriichi was away searching for someone to assist with the delivery. The loss of his young family was what drove him to join the Demon Slayer Corps and swear revenge against Muzan.
Cradle of Loneliness: After coming home only to discover his wife and their unborn child had been killed by some demon, Yoriichi held them in his arms for 10 days. He only stopped when a demon slayer (implied to be Rengoku's ancestor) came and broke him out of his shock enough to give the dead a proper burial.
Curb-Stomp Battle: Yoriichi dealt one to Muzan. He cut Muzan into pieces almost immediately, who was unable to fully recover due to the Sun Breathing's stifling effect on his regeneration. He was only able to survive by splitting himself into 1800 pieces and fleeing in terror, and even then Yoriichi was able to slice up 1500 of his pieces instantly. To top it all off, the wounds Yoriichi inflicted have not healed in the centuries since their encounter, acting as a permanent reminder of Muzan's helplessness and terror during that moment.
Dented Iron: Yoriichi's skill may have been as sharp as it was during his prime but at over-80 years of age, his body just could not go any further and Yoriichi passed away before he could deliver the finishing blow to Kokushibo.
Died Standing Up: Defiant to the end. As an 80-year-old man, Yoriichi died while trying to put his demon brother out of his misery. He actually seemed to have the upper hand in his final battle, but due to his old age, Yoriichi's body just gave up at the last second, and he died standing with his sword still in hand.
Dissonant Serenity: A tame example, but Yoriichi is constantly shown with a flat and impassive expression, with Kokushibo noting that he had never seen him show a hint of emotion until Yoriichi shed tears upon seeing how his older brother had given up his pride and humanity and become a demon. This is his usual countenance, even when he's slaying demons.
Dramatic Irony: His wish was to live a happy life with his family, but he lost it all when a demon killed them when he was away. His own twin brother who wanted to be strong just like Yoriichi already had such a life when the two met up again as adults, but gave it up in pursuit of strength.
The Dreaded: To Muzan, as Yoriichi was the demon slayer who almost killed him. Even as an old man on death's door, Kokushibo knew he stood no chance of defeating him. Muzan's sheer terror of the man is such that when Tanjiro ends up resembling him through a combination of his Sun Breathing technique and his sheer rage towards demons who disrespect the sanctity of life, the cells he implanted in the 12 moons cause them to experience vivid flashbacks of Muzan's encounter with him— to repeat, Muzan's very cells carry his deep terror for the man who came closest to inflicting death upon him despite all his precautions and abilities. Muzan even went out of his way to destroy any record of the Sun Breathing style and killed most of the inheritors of the technique himself, despite his usual paranoia with being identified, out of fear of another like Yoriichi appearing before him again. Even a mere look at the earrings that were originally Yoriichi's is enough to cause Muzan to shake in terror.
The Drifter: After being expelled from the Demon Slayer Corps over being pointed as the scapegoat for a string of factors that ranged from Muzan escaping to his own older twin brother betraying the Corps to join Muzan himself, Yoriichi at first went back to the home he lived with his late wife Uta, but upon first meeting and making friends with the poor couple that had stationed there, Sumiyoshi and Suyako, Yoriichi decided to give that home to the Kamados ancestors, and going on to become a drifter, a ronin in all but name, to kill any number of demons he can find for the rest of his life as a tragic act of self-appointed atonement over failing to kill Muzan for good.
Dull Eyes of Unhappiness: He had these for most of his life, signifying his alienation from other people due to his see-through-sight, along with his search for his purpose in life. Then later, his failures in defeating Muzan, and protecting his family and others despite his strength.
Dying Alone: The most powerful demon slayer, who came close to killing Muzan Kibutsuji and dedicated his whole life to exterminating demons, a Samurai dedicated only to his craft. He never stopped to pursue any happiness for himself after his wife and unborn child were killed in his twenties, instead choosing to die alone 60 years later in one last match against a demon he knew very well, his own twin brother.
Early-Bird Cameo: He first appeared briefly in a flashback of Muzan's about their encounter, remembering the earrings since they're the same as Tanjiro's.
Evolving Weapon: Yoriichi had a black blade like Tanjiro does, but unlike all normal demon slayers who permanently enhance the color of their blades due their Breathing affinity when they touch it for the first time, Yoriichi could make his black blade turn red at will when he engaged in battle, showcasing his proficiency in Sun Breathing. Interestingly, Yoriichi compared his wife Uta's eyes to obsidian the day he met her.
Face Framed in Shadow: The very first time he's shown in the anime, he's depicted with his face overshadowed, adding to the enigmatic and domineering presence that left Muzan traumatized from their encounter years after.
The Faceless: Whenever Yoriichi appears, his face is usually obscured completely or partially to add mystique to his character. It finally gets revealed properly in the Season 3 premiere.
Failure Knight: The fact that Yoriichi failed to kill Muzan (with the added insult that he only escaped because Yoriichi's kindness distracted him when he noticed Tamayo's sad nature on the sidelines) weighted him down immensely, since Yoriichi came to realize he was pretty much the strongest demon slayer to ever live, thus knowing very well Muzan would be responsible for many deaths to come without anyone at the time being able to put a stop to that terror.
First Love: Uta is his. She's also his only love, as he's never interested in anyone else for the rest of his life.
Friend to All Children: Yoriichi loved children very dearly. It was his dream to become a father for his and Uta's unborn child, and his interactions with Sumiyoshi's children were very kind and gentle.
From Zero to Hero: Though he had incredible talent, Yoriichi was perfectly content with living a peaceful life with his family because he didn't like hurting people. Then Uta was killed with their unborn child because of a demon, and the resulting Heroic BSoD had Yoriichi dedicate his life to ending Muzan. Even though he wasn't successful (although he came very close to doing so), his techniques and skills remained as part of the Demon Slayers and Muzan is still terrified of him centuries later.
Good Cannot Comprehend Evil: Like Tanjiro, Yoriichi didn't understand what was so enjoyable about trampling on the lives of others as Muzan had done so many times. He also didn't see the envy and despair fermenting in his own twin brother's heart until it was too late.
Greater-Scope Paragon: Even though he wasn't the founder of the Demon Slayer Corps (being born centuries after Muzan's rise to power), he was the creator of the Breathing Styles—with Sun Breathing being the progenitor of all other Breathing Styles which inspired the creation of the Hashira. Yoriichi also handed down his earrings to Tanjiro's ancestor, Sumiyoshi, along with Sun Breathing, as Sumiyoshi himself would later pass it to his descendants, ensuring its continuity.
Guilt Complex: Failing to kill Muzan for good absolutely destroyed his spirit, despite the fact both Yoriichi and Muzan knew he was ridiculously stronger than the demon king, but Muzan had a surprise escape maneuver Yoriichi couldn’t fully overcome, and he was slightly distracted by Tamayo, a demon who didn’t seem as malicious as all others, looking somewhat tragic even. That encounter was immediately followed by Yoriichi’s own twin brother Michikatsu betraying the demon slayer corps to become a demon himself, joining Muzan; all led to Yoriichi’s complete disgraced image by association, being expelled from the Corps as result. Yoriichi summarized all of what happened to him being personally responsible for all deaths enacted by demons thereafter due Muzan escaping his grasp, the man just gave up on a normal life altogether since, dedicating the rest of his life to exterminate any number of demons he can find if Muzan just keeps hiding till Yoriichi dies of old age.
Half the Man He Used to Be: After he expired during his duel with his older twin brother, Kokushibo slashed his body in two under the pretense of ensuring his death, but it was more of a fit of jealousy and impotent rage.
Happily Married: His marriage with Uta was the happiest and most peaceful time of his life, and he wanted nothing more than to continue his life just like that. Unfortunately, it didn't work out due to circumstances beyond his control.
Heartbroken Badass: Yoriichi started his life-long career as a demon slayer after his wife and child's death, never seeking personal happiness again. His heart was broken a second time when his brother chose to become a demon.
Heroic BSoD: Had a huge one after discovered the bodies of his wife and unborn child in their house. Even after the worst had passed, Yoriichi never quite recovered and chose to live his life alone, dedicating himself to the single goal of killing Muzan.
Heroic Self-Deprecation: Despite being such a legendary skilled swordsman, he was quite melancholic. He didn't see himself as a person of worth since he ultimately failed to kill Muzan, and couldn't protect his wife and unborn child or prevent his brother from walking the path of a demon.
Horrifying the Horror: Muzan, who's a Humanoid Abomination is scared shitless of him to the present day.
Humble Hero: He was kind and respectful, never putting himself above others. In his youth, he told his brother Michikatsu, later Kokushibo, that if Michikatsu dreamed of being the greatest, most powerful swordsman who ever lived, then Yoriichi would be satisfied just being the second strongest. He really was a sweet child in the past, so far as to even refusing to become the family's successor so that he wouldn't usurp Michikatsu and willfully left early to become a monk. It's revealed that he didn't even go to the temple because he knew their father would attempt to bring him back, and he left no trace of himself so that Michikatsu would surely achieve the position.
The Idealist: A major trait in Yoriichi’s character is that he believed in an ideal where the true solution to erasing the suffering humanity endured through being hunted by demonkind would be accomplished by demon slayers, and everyone that supported the cause, reaching "the same place in the end", which Tanjiro interpreted as everyone’s qualities and strengths eventually amounting the effort needed to kill Muzan once and for all even if no one could have grown to be as a strong as Yoriichi ever was; that’s why Yoriichi never let it go of this ideal despite growing to be very self-deprecating after failing to kill Muzan, since in his belief Yoriichi ended up being just a failing piece of a much a larger group that would surely one day "reach the same place".
I Just Want to Be Normal: In contrast to his brother, Yoriichi just wanted to have a mundane life free of conflict with his wife and family. Unfortunately, Muzan and the demons made that impossible and Yoriichi ended up locked on the path of the sword in order to purge the world of their evil, outright saying that he was born specifically to slay Muzan.
I Let Gwen Stacy Die: He holds himself responsible for failing to protect his wife Uta and his child.
The Immune: Somehow escaped the curse of the Demon Slayer's Mark. It's noted that no bearer of the Mark lives past 25 years of age, yet Yoriichi went on to live to 80 years and with his skills intact.
Implausible Fencing Powers: His swordmanship was so impossibly complex that a combat training dummy modelled after him to train Demon Slayers had to be installed with six arms to even begin to emulate his techniques.
Inexplicably Awesome: Other than being "blessed by the gods", the explanation for why Yoriichi is so inhumanly powerful is never given. He was simply born that strong, Having had access to Full Concentration Breathing, the Demon Slayer Mark and the Transparent World, techniques that are supposed to take lifetimes of effort to achieve, since childhood.
Invincible Hero: Yoriichi went his entire life unchallenged in battle, utterly trivializing the skills of anyone he fought. Both his brother Michikatsu/Kokushibo, the strongest of the Twelve Kizuki by a very large margin, and Muzan, the most powerful demon to ever exist, stood no chance against him at all. He dealt with them as if they were just ordinary demons.
Kill the Ones You Love: Yoriichi loved his older twin brother Michikatsu very much. It took him well over 60 years to steel his heart in order to seek Michikatsu, now the powerful demon Kokushibo, to battle him to the death; Yoriichi was fully intending to kill Kokushibo before he died of old age. He must have felt his life wasn't long in this world anymore, so he decided to at least try to atone for his brother's betrayal of the demon slayer corps and save him the shame of living as a terrible human eater and murderer. However, Yoriichi died mid-battle despite having the complete upper hand against Kokushibo; his powerful and gifted human body just couldn't defeat aging, allowing Kokushibo to live for a few more centuries.
Life Will Kill You: Despite being the strongest demon slayer ever born, he never met his end in some heroic, grandiose way. Rather, he died of old age in his duel against his brother, passing away just before giving him the killing blow.
Long-Dead Badass: Yoriichi has been dead for centuries by the time of the present story, but his influence on the setting is still heavily felt.
Manly Tears: He shed tears before his fight against Kokushibo, knowing that his former older brother Michikatsu betrayed him and became a demon, the sworn enemy they were supposed to fight against.
Master Swordsman: Presented as a legend who wielded the most complete Breathing form ever and the origin of all others, the guy still managed to retain his abilities as an 80-year-old samurai, noted by his own twin-brother-turned-demon who still felt apprehensive against an old man who looked much more spent than the ageless Kokushibo. In his youth, he was the only one who ever came close to defeating Muzan.
- Yoriichi was such a inhumanly fast and powerful swordsman that the only way anyone's found to replicate his moves, even 300 years later, is through a mechanical doll with 8 limbs. Evidently it's just not possible for anything with just two arms to do what he can.
Meaningful Name: His given name is comprised of the kanji for " destiny, fate" and the Japanese term for 1, so it's possible to translate Yoriichi as "destined to be number one". However, Akeno, Yoriichi's mother, the one who named him gave him that name because she wanted him to treasure the bonds he would form while Michikatsu's name was given by their father who wanted his son to always win. While his family name "Tsugikuni" contains the kanji for "inherit, succeed", referencing how so many slayers are desperate to live up to Yoriichi's legacy.
Monochromatic Eyes: To convey how terrifying his presence is to any demon who is unlucky enough to be on his path, Yorichi’s eyes were drawn in blank white, and his face is obscured by shadow in the first tease of his existence, during Muzan’s recollection of their encounter, the king of demons was reduced to a trembling mess in the face of the strongest Demon Slayer to ever exist. The same effect is repeated when Daki recalls Yoriichi through Muzan’s cells in her bloodstream itself being afraid of him, as Tanjiro triggered those memories.
The Mourning After: Although Uta died when he was seventeen at most, he continues to mourn her and never loves anyone else for the rest of his life.
My Greatest Failure: He never forgave himself for failing to kill Muzan, knowing how many would die as a result. His failure to protect Uta and their unborn child never left him either.
Nice Guy: Not just an unbelievable warrior, but a kind, generous and warm man. It's revealed in chapter 177 that he was always a very sweet person since childhood. He loved his family very much and did not object to his father's treatment of him. He felt bad for his father's retainer, Ito, after using his special talent and injuring him in his sword training. He also helped his ill mother by walking alongside her and supporting her left side, when she could not walk on her own. He treasured the flute that Michikatsu made for him, telling him that he would always remember his big brother after he prepared to travel to a temple. He didn't even stay at the temple and left on his own journey so that his brother would become the next successor to their family.
Nice Job Breaking It, Hero: It's true that Yoriichi rescuing Tamayo from Muzan's control would later help immensely with finding a cure to turn demons back to humans, but still, if Yoriichi didn't get distracted, he most likely would've killed Muzan and stopped every bad thing in the story from taking place.
No Good Deed Goes Unpunished: Poor Yoriichi goes through these.
- Not telling his family Akeno had an illness that led to her death. To be fair, he never talks because he believes his father's talk of being an omen to their family so he wanted to protect his family. Plus, this also led to Michikatsu hating him because of how special he actually was.
- When Uta was in her last stage of pregnancy, he went to fetch a midwife but stopped to help bring an old man to see his deceased son. When he came back at night, Uta and their unborn child were killed by a demon, meaning if he didn't stop to help the old man he probably could have prevented his wife and child's deaths.
- Yoriichi saved Tamayo from Muzan's control, however, the other Demon Slayers argued that this was against their rules and Yoriichi ended up getting banished from the organization.
No Place for Me There: He was banished from the Demon Slayer Corps after he failed at killing Muzan for good as the demon king escaped through his grasp. The Corps turned on Yoriichi due a combination of events that were all placed as his fault, even if indirectly, such as Muzan fleeing, Yoriichi sparing a demon (Tamayo) because he felt she should be free to live after Muzan’s curse on her had broken, and the worse of all: his own twin brother betraying the Corps to turn into a demon. Michikatsu committed the highest act of treason by killing the then current Lord of the Ubuyashiki family, bringing his head as a sign of submission to Muzan; the Lord’s son became the new leader and oversaw Yoriichi’s trial, with his banishment actually being a merciful sentence by the new young master since the Corps wanted Yoriichi executed instead. All the good Yoriichi did for the Demon Slayer Corps was not enough for him to be pardoned; the man that literally invented Breathing Styles, giving the once mere human Samurai a chance to become superhuman and have any chance against demons, was thrown away.
Not So Stoic: Turns out Yoriichi just wasn't good in expressing his emotions properly, noted as not even having cried as a baby normally would in their first years of life. He was in fact very kind, but his reactions could be interpreted as apathy by those who didn't want to see Yoriichi for what he truly was. In his advanced age, Yoriichi grew to properly show sorrow for his brother Michikatsu at last, who turned into a demon and betrayed the demon-slaying path. Seeing him crying was something Michikatsu noted he had never seen Yoriichi do before. But the first time he actually cried was when he went to visit Sumiyoshi and played with Sumiyoshi's child Sumire because it showed him what he would miss with his own unborn child.
Official Couple: With Uta, and they were expecting children together before she died. In the epilogue, they've been reincarnated and have fallen in love again, this time able to live the happy life together that they wanted.
Old Master: As an over-80-year-old man, Yoriichi was still able to use his swordsmanship skills in the same way as he did in his prime. He managed to slash Kokushibo's neck, something that the latter finds unfair, as he became a demon who retained his youth while his brother remained human, yet still could boast that much skill as an elder.
Passing the Torch: It can be seen that he, as an over-80-year-old man, no longer had the hanafuda earrings. By that point, he had already passed his will on to Tanjiro's ancestors. Yoriichi ”taught” Sumiyoshi by proxy the Sun Breathing Style when he humored the latter's wife Suyako's desire to see him practice once again, then passed his earrings to them after that. Sumiyoshi pledged to pass the earrings and Sun Breathing down his family line out of gratitude for saving his family's lives.
The Perils of Being the Best: Yoriichi being the strongest demon slayer to ever exist in the story brought him nothing but constant misery and loss. His hidden strength unintentionally caused a succession dispute between his older twin during their childhood and coupled with his difficulties expressing emotion made him rather isolated. To note, the happiest moments of his life were just living quietly with his wife for a few years, where his strength wasn't needed at all.
Red Is Heroic: Yoriichi wore a red haori and had a mysterious power that allowed him to turn his Nichirin Sword from black to red.
Reincarnation Romance: He and Uta are eventually reincarnated and fall in love all over again, finally having the family they were deprived of. They are seen in the final volume extras, labelled "a very happy couple".
Retool: In the series proper it looked like Yoriichi was completely shunned by all his comrades in the Corps once he was pinned as a scapegoat for Muzan escaping and his brother Michikatsu betraying them to become a demon himself. However, the 2nd Databook went on to further explain Yoriichi wasn't completely shunned after all: some of his former companions still appreciated him, often meeting Yoriichi outside the Corps' domain to casually talk and trade information on demon sightings. With that Yoriichi's banishment tragedy isn't erased, but the result is somewhat lessened.
Rōnin: That's what de facto turned out to be of Yoriichi once he was expelled from the Demon Slayer Corps, he was no longer an employed Samurai in a time they were still in place, the Sengoku Period, and Yoriichi was born from a Samurai family; the man was still resolute in trying to eradicate demonic threats and Muzan for as long as he lives, so he just became a Ronin, fighting against evil all by himself till he died in his final battle, 60 years after his lone pilgrimage started.
Samurai: Yoriichi was from the Sengoku period where the Samurai were still around. Since the demon slayers weren't quite what they are now, Yoriichi was better known publicly as a samurai instead of a demon slayer.
Screw the Rules, I'm Doing What's Right!: Yoriichi chose to help Tamayo, a demon, during his fight against Muzan. Obviously, this didn't sit right with the rest of the Demon Slayers and he was branded a traitor.
Shrouded in Myth: Despite being the guy who made Muzan shake in his boots, Yoriichi and the Tsugikuni family, in general, don't seem to be well documented within the Slayer records. Any info on their legacy is quite limited and sparse.
Single-Stroke Battle:
- How his last battle went down. Yoriichi, as an old man, gave his all into one attack that really got Kokushibo by surprise, but it only slashed his neck. After that, Yoriichi's life just expired, and he died standing with his sword in hand.
- This is how his battle with Muzan went as well. The first second, Muzan launched just one attack at Yoriichi which the latter dodged. The second after, Muzan was literally trying to hold his body together in vain after Yoriichi cut him up into pieces with his red blade.
Silent Scapegoat: The strongest demon slayer to ever live was an extremely humble man, unfortunately so, as he never even tried to fight the injustice that was inflicted on him after fighting against the series' main villain, Muzan Kibutsuji, four hundred years in the past. Yoriichi silently took all the barrage of accusations made by his own Hashira colleagues of the time for Muzan escaping his clutches, despite being the sole person to ever come close to defeat him; and for letting Tamayo, a demon, go, for Yoriichi saw her as an unwilling companion to Muzan who was now freed of her torment. Everything got worse when Yoriichi's own twin brother betrayed the Corps around the same time to become a demon himself. All of that made Yoriichi a scapegoat: they were demanding for his death, and he himself was silently taking it all since he did blame himself too, but he was given some leniency by being expelled from the Demon Slayer Corps instead.
Single-Target Sexuality: He only had eyes for Uta. After the death of his wife and unborn child, he never found love or started a family again since Uta was the only person he ever loved.
The Stoic: Noted to be a very composed Samurai who rarely showed his emotions. He seemingly was a determined man who gave his all to slay demons. However, it seems he enjoyed the company of more expressive people, like his friend Sumiyoshi.
Super-Speed: An absolute master of the Flash Step. All his battles ended with one swing of his sword and then the demon trying to figure out what the hell happened in that split-second. Sumiyoshi also witnessed this when Suyako went into labor and Yoriichi rushed to find a midwife.
Sympathy for the Devil: He wept when he saw his older twin brother as a demon and gave him genuine sympathy for throwing away his pride and morality just to prolong his strength.
Tears of Joy: Yoriichi cried when he played around with Sumiyoshi's child Sumire because she reminded him of his own child who he would never see grow up.
To Be Lawful or Good: Ran into this during his fight with Muzan when he noticed a reluctant looking Tamayo with him. Yoriichi chose to be good and save her, but it came at the cost of being banished from the Corps.
Tragic Dream: Yoriichi tells Sumiyoshi (Tanjiro in his memory) that all he wanted was to live in a small, quiet home with his wife Uta and their newborn child, both of whom were killed by a demon.
Tragic Keepsake: As a child, Yoriichi was given the hanafuda earrings by his mother and a handmade wooden flute by his twin Michikatsu. While he passed on the hanafuda earrings to Sumiyoshi and his family line, he never stopped carrying his brother's flute, not even when in death as an 85-year-old man, long after Michikatsu became the demon Kokushibo. The flute was kept encased in a small piece of fabric, with the same pattern as his long-deceased wife Uta's kimono; Yoriichi kept the memories of his most cherished people close to him through all his life.
Training Dummy: Midway into the series, we're shown an automated training dummy named Yoriichi Zeroshiki, said to be modelled after a powerful slayer with skills so absurd that the doll had to be given six arms with a katana on each hand just to emulate what the 2-armed slayer was capable of. It's eventually made clear that it was modelled after Yoriichi, even sharing his name.
Tranquil Fury: His face is shown to have been visibly angered when he encountered Muzan for the first time.
Trauma Conga Line: Poor, poor Yoriichi.
- At birth, Yoriichi was almost killed by his father because of the Demon Slayer Mark on his forehead. While he was saved by his mother Akeno, he was treated as an outcast by his father and the rest of the family. He was isolated in a small room, fed poor food, given poor education and clothing, and—as the Sengoku rumors revealed—was verbally abused by his father to the point where he thought of erasing his own existence at two years old.
- It’s revealed that Yoriichi knew that his mother was dying from an illness and tried to support her as much as he could. Upon her death, Yoriichi ran away from home to protect his brother from the same abuse his father had inflicted on him.
- Yoriichi runs away and meets a girl named Uta, who he eventually falls in love with. In time, they get married, and decided to have a child together. However, when Yoriichi leaves to get the midwife, he returns home only to find his wife and unborn child dead, having been killed by a demon. Yoriichi is absolutely devastated and is so horrified that he holds onto their corpses for ten days.
- Yoriichi confronts Muzan himself and almost kills him. However, Muzan flees just as Yoriichi was about to finish him off, leaving him feeling guilty that his failure meant that plenty of people would lose their lives.
- Right after that, Yoriichi realizes that his beloved older brother—Michikatsu—had betrayed them and took the path of a demon.
- He then proceeds to take responsibility for failing to kill Muzan, setting Tamayo free, and Michikatsu turning into a demon… causing the demon slayers to turn on him and demand his death. He is banished from the Demon Slayer Corps shortly afterward.
The Un Favourite: A straight example that then subverts itself, yet it does not make the tale end in a brighter note. In his first 7 years of life, Yoriichi was seen as a complete anomaly born in a family of Samurai in the Sengoku Period: he was seemingly too quiet, looked frail, barely spoke at all and never cried, to the point his parents thought he was deaf; as such his father completely gave up on Yoriichi ever learning anything of worth as a warrior, favoring his older twin Michikatsu who seemed livelier and actually wanted to become a warrior instead. Meanwhile Yoriichi was borderline disowned by their father, forced to live in a small side installation near their mansion, like he was an unwanted presence. However, in a complete innocent action of Michikatsu's swordsmanship instructor who was just trying to humor Yoriichi by telling him to play with him in a mock sparring session, the kid completely destroyed the instructor in what was supposed to be just light play time. Yoriichi at 7 years old showed something that could only be a divine given gift to sword fighting; that event made the Tsugikuni father completely invert the treatment of his twin sons - he now wanted Yoriichi to be his successor, and Michikatsu to be the shunned child. In the end Yoriichi loved his older brother Michikatsu and wanted nothing with his family's warrior creed and dispute for succession, so he ran away from home as a kid. His father was left desperately searching for Yoriichi, but once he could no longer find his prodigious son, Michikatsu was his only option left to succeed the Tsugikuni family.
Walking Spoiler: As a very important character in the lore, it's impossible to mention Yoriichi without spoiling key elements of the story.
When He Smiles: The last time Yoriichi ever smiled was when he left Sumiyoshi, who gave him a You Are Better Than You Think You Are speech. Due to how generally inexpressive he was, the few times that he did smile are always emphasized by large panels and light.
Wise Beyond Their Years: As a seven-year-old child, he was the only member of his family who understood the severity of his mother's failing health and did everything he could to support her until she died. He was also aware of his father's pragmatic view of the family's succession and knew he would usurp his brother Michikatsu's place as heir due to his clearly superior swordsmanship, and chose to leave the household on his own terms to spare his brother of this fate.
World's Best Warrior: He was the Demon Slayer. So overwhelmingly powerful that even Muzan went down in an incredibly one-sided Single-Stroke Battle against him and remains terrified of him long after his death. Literally the only reason that he didn't win his final fight against Kokushibo was that he was at least eighty and his body just gave out on him before he could properly inflict a killing blow. To put that feat in perspective, when Kokushibo is fought in the series proper, it takes multiple Hashira working together, a few Heroic Sacrifices, and Kokushibo suffering a What Have I Become? moment and a Villainous BSoD to put him down for good. This guy almost did it by himself while on death's door. Likewise, the only reason he didn't kill Muzan was because he paused his onslaught to ask Muzan what he thought of all the lives he took, which gave Muzan the opening he needed to escape.
World's Strongest Man: In addition to being an inhumanly good swordsman, Yoriichi is extremely strong. The first example we get of this is when he was a mere child and knocks out a full-grown sword instructor with a practice sword, even leaving huge welts that took weeks to go away. The damage he can do to powerful demons like Kokushibo and Muzan is nothing to sniff at, especially when you consider that his Sun Breathing is a perfect combination of absolute strength and lightning speed.
Worthy Opponent: Yoriichi is one of very few people Muzan has genuine respect for, albeit begrudgingly as in the end Muzan just can't deny how strong Yoriichi was; even considering the present demon slayer to be vastly inferior to the man who nearly killed him 400 years ago.
You Are Better Than You Think You Are: Sumiyoshi told him that his life did have meaning despite his failures since he saved Sumiyoshi and his family. Yoriichi was so touched that he gave one last heartfelt smile to them before he left forever. His descendant Tanjiro echoes that sentiment 400 years later, by saving Tamayo's life (which she later repays by providing the medicine needed to turn Nezuko back into a human).
You Remind Me of X: The Sengoku Rumors section in the 22nd Volume fully reveals the house Sumiyoshi and Suyako live in, and eventually the Kamado Family centuries beyond, was the very house Yoriichi and Uta used to live in; the poor couple moved in thinking it was completely abandoned, but after Yoriichi became acquainted with them he saw Sumiyoshi and Suyako as the couple he wished himself and Uta could be, giving the house away to them, hoping they have the happy humble life he could never have.

Butterfly Estate

General

Current residence of the Insect Hashira, Shinobu Kocho, and her assistants. A large manor that serves as a hospital and training place for Demon Slayers.

Amazon Brigade: Kanae, Shinobu, Kanao, and Aoi are all certified Demon Slayers.
Heartwarming Orphan: With the exception of Kanao who was rescued from her AbusiveParents, the girls living in the estate have all lost their families to due demons. Despite this they hard-working supportive girls, and although Aoi is a bit rough around the edges, they are all easy to get along with.
Orphanage of Love: Unconventionally, but Kanao, Aoi, Sumi, Kiyo, and Naho were orphaned or otherwise abandoned by their parents and taken in by the Butterfly Estate, living and working there in exchange for room and board.
Signature Headgear: All the women and girls of the Butterfly Estate wear brightly colored butterfly-shaped hairpins or hairclips.

Aoi Kanzaki

Voiced by: Yuri Ehara (Japanese), Reba Buhr (English)^{Other VA}

A Demon Hunter who is a caretaker of the Butterfly Estate.

Blue Is Heroic: She's heavily associated with the color and is even named after it, and she's also on the Demon Slayers side.
Color-Coded Characters: Blue is her theme color. Her name is the word for blue, her eyes are blue, her butterfly hairclips are blue, she is a Water Breathing user and she gets married to a boy with blue hair highlights.
The Comically Serious: Aoi always takes herself very seriously, which leads to some amusing interactions whenever she has to deal with the Hot-Blooded Inosuke and/or the love-hungry Zenitsu.
Cool Big Sis: Being older than all three of the leading boys and more emotionally mature and responsible, Aoi officially takes this role in the Butterfly estate whenever Shinobu is absent and/or assigned to combat duties.
Damsel in Distress: Forcefully drafted into a demon-slaying mission by Tengen Uzui who needed female Demon-Slayers in order to infiltrate a prostitution ring to save his wives. Luckily Tanjiro, Zenitsu, and Inosuke volunteered to go in her place.
Formal Characters Use Keigo: As is fitting for her serious, uptight attitude, she speaks in polite Japanese to everyone around her.
Generation Xerox: A non-blood related example. Aoi acts similar to Shinobu prior to the latter taking on her sister's more cheerful traits, acting uptight and strict, but at the same time, kind-hearted and dependable.
Girlish Pigtails: She wears those on either side of her head held up by blue butterfly hairpins, showing her young age.
Hooked Up Afterwards: The final volume reveals she got married to Inosuke and they had a family together.
Lovable Coward: She may be too scared to fight despite passing the Final Selection, but she is a diligent, respectable, young girl.
Making a Splash: The second Fanbook reveals Aoi is a Water Breathing user as well; it is the most common Breathing style within the Demon Slayer Corps.
Meaningful Name: Aoi means "blue," referring to the color of her eyes and the blue butterfly-shaped ornaments in her hair. She's also a Water Breathing user.
The Medic: Her role despite being a qualified Demon Slayer. Unlike Shinobu and Kanao, Aoi would rather hang around the Butterfly Estate tending to wounded Demon Slayers than going out slaying demons herself.
Not So Stoic: Aoi usually keeps her composure at all times with a stern face, but she is visibly scared when Tengen attempts to forcefully take her on his mission, and bursts into tears when Tanjiro awakes from his coma, as she is so relieved to see him getting better. She weeps even more when she remembers Inosuke's grievous injuries sustained in the Entertainment District. Then she sports a Comical Angry Face when she sees a recovered Inosuke clinging to the ceiling, mad at him for making her worry so much.
Only Sane Woman: When it comes to Zenitsu and Inosuke, she really doesn't tolerate their behavior. Especially for Zenitsu after the swordsmith village arc when he starts gushing over Nezuko walking in sunlight and talking again. Aoi is clearly annoyed by Zenitsu's antics and tries to stop him from bothering Nezuko. But, when Nezuko accidentally calls Zenitsu "Inosuke", Zenitsu ends up getting mad at Inosuke and plots to get his revenge, to which Aoi criticizes Zenitsu since his plot for vengeance and angry face is clearly scaring everyone.
Perpetual Frowner: Aoi usually has a serious scowl on her face, sometimes even when she's not angry.
Ship Tease: With Inosuke of all people several times.
- When talking about Haganezuka's fondness for rice dumplings, Inosuke demands some for himself. Aoi is unusually patient with him, responding that she'll buy some for him later with a tender look and smile.
- She tearfully recounts Inosuke's critical condition when he first came back from the Entertainment District, visibly still shaken by the ordeal, despite him already having recovered at the time.
- In the penultimate chapter, invoking from him a Luminescent Blush and an uncharacteristically tender smile when she gives him his own personal plate of food; eventually they become a couple, as the series’ final volume confirms Aoba Hashibira is their descendant indeed.
Sugar-and-Ice Personality: Aoi usually acts stern and serious, especially when dealing with difficult patients such as Zenitsu and Inosuke, but at the same time she is also kind-hearted and very dependable.
Team Mom: Given that Aoi is likely the oldest girl in the estate, she is the most responsible and diligent.
Tears of Joy: When Tanjiro regains consciousness following his fight with Upper-6 Daki and Gyuutarou, Aoi starts crying out of relief and guilt because Tanjiro almost died in the mission he took in her stead.
Through His Stomach: Though she doesn't seem to have romantic intentions, giving Inosuke his own plate of food leaves him visibly happy.
Tomboy and Girly Girl: Comparatively, she's the tomboy to Kanao and Shinobu's Girly Girl, though she's girly herself.
Tomboy with a Girly Streak: As The Medic, she deals with the more delicate side of bedside care, but she's still a Demon Slayer and provides rehab training to the convalescent.
True Blue Femininity: She typically has blue clothing and she's a very caring medic, despite her uptight exterior.
Tsundere: Type A. Out of the three male leads thus far, Tanjiro is the only one who she shows her dere-dere side to. Aoi finds Inosuke abnormal and has zero patience for Zenitsu's overdramatic antics. She would eventually warm up to Inosuke as well during the timeskip, to the point of starting a family.
When She Smiles: She gives Inosuke a tender smile when he asks to have rice dumplings, telling him she'll get some for him later.
Wise Beyond Her Years: Aoi is a young teenager, but carries herself with the maturity and professionalism of a grown woman.
You Are Better Than You Think You Are: Aoi feels a bit less of an important member of the Demon Slayers because while she did take the selection exam to fight demons and passed, Aoi sees it as pure luck, explaining that she is too scared to actually fight demons and prefers to volunteer as a medical and training assistant in the Butterfly Estate instead, away from immediate danger. Tanjiro doesn't agree with Aoi thinking she is less of a slayer because of that, and reassures her that she is an important part of the Demon Slayers thanks to her medical skills. Receiving this much gratitude and praise takes Aoi back a little.

Kiyo Terauchi voiced by: Nanami Yamashita (Japanese), Jackie Lastra (English)^{Other VA}

Naho Takada voiced by: Yuuki Kuwahara (Japanese), Kimberly Woods (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/kny_butterfly_assistants.jpg

Top to bottom — Naho, Sumi, Kiyo.

Three young girls who work as servants at the Butterfly Estate.

The Baby of the Bunch: Collectively, they are the youngest of the girls who live and work at the Butterfly Estate.
Black Bead Eyes: They have dotted eyes as their default expression.
Brutal Honesty: Although they are very nice, sometimes they are capable of this. When Zenitsu is leaving and asks if they will miss him, they say that they will not.
Cheerful Child: They're always friendly and happy, and greet patients with a smile.
Children Are Innocent: They are very sweet and kind little girls who are ready to help people out. On the cover of chapter 129, Sumi is even trying to feed an injured Genya at the Butterly Estate, but because Genya reached puberty, he gets nervous and politely tries to decline.
Color-Coded Characters: They all wear the same outfit and butterfly hair decorations, but they're accented with different colors in order to tell them apart; Sumi wears blue, Kiyo wears pink, and Naho wears green.
The Cutie: Three sweet, polite and cheerful little girls always willing to help out anyone who needs it.
The Dividual: The three of them are rarely seen apart. They also look and sound very similar, and they more or less all share the same personality. If it weren't for the fact that they have different family names, one could easily mistake them for triplets.
Girlish Pigtails: Sumi wears those to show her young age.
Heroic Bystander: When Tengen kidnaps Aoi and Naho for a mission to the Entertainment District, Sumi, Kiyo, and Kanao grab onto him to slow him down until Tanjiro arrives.
Identical Twin ID Tag: While they're not related, they look almost identical, with only their hairstyles, sash colors, and butterfly hairpin colors being different. Naho wears green and has braids, Sumi wears blue and has pigtails, and Kiyo wears pink and has short, straight hair with bangs.
The Medic: They work as nurses, treating injured Demon Slayers who come to the Butterfly Estate.
Nice Girls: Very sweet, cheerful, and polite little girls who are always ready to lend a helping hand to everyone in need.
Non-Standard Character Design: Most characters in the series have eyes that only turn into dots during comedic moments, but Sumi, Kiyo, and Naho always have dot eyes, regardless of the situation.
Parental Abandonment: It's implied by Kocho that all three girls lost their parents and families to demons and were taken into the Butterfly Estate to support them.
Pink Means Feminine: Kiyo's butterfly hairclips and sash are pink.
Precocious Crush: All three girls have a crush on Tanjiro since he's so nice and friendly to them. Although in chapter four of the second light novel, Sumi might have developed an attraction to Genya when she properly meets him in the Butterfly Estate after the Swordsmith Village arc. This happened because Genya stood up to protect the girls when an angry Demon Slayer member had a breakdown at the estate. After the situation calmed down, Sumi was in charge of caring for Genya and later on decided to bond with him after getting to know him.
Prone to Tears: Being little girls, they tend to cry easily, such as when Aoi and Naho are kidnapped by Tengen for a mission to the Red Light District, or when Tanjiro wakes up from his two-month coma after the fight with Daki and Gyutaro.
True Blue Femininity: Sumi's butterfly hairclips and sash are blue.
Wise Beyond Their Years: They appear to be pre-teens or slightly younger, but are fully trained nurses capable of treating wounded Demon Slayers. They also help with cooking, cleaning, and rehabilitation training.

Kakushi

In General

Female Kakushi who accompanied Tanjiro to the Butterfly Mansion voiced by: Hisako Tōjō (Japanese), Jennie Kwan (English)

Female Kakushi who guided Tanjiro to the Swordsmith Village: Iori Saeki (Japanese), Cristina Valenzuela (English)

Other Kakushis voiced by: Ayaka Shimizu, Shinya Takahashi, Yoshiaki Hasegawa, Yusuke Tonozaki (Japanese); Griffin Burns, Erik Kimerer, Alejandro Saab

https://static.tvtropes.org/pmwiki/pub/images/kakushi_dancing_with_the_kasugai_crows.png

The Kakushi are a brigade responsible for different tasks pertaining to providing support for the Demon Slayers.

Badass Normal: Despite only being in support roles, they partake in the final fight against Muzan by using cars to prevent him from trying to escape.
Big Damn Heroes: See above.
Butler Space: They sometimes pop out of nowhere, for example a female Kakushi suddenly appearing when Tanjiro leaves the swordsmith village.
Buxom Beauty Standard: The two unnamed female Kakushis that accompany Tanjiro to the Butterfly Mansion and the Swordsmith Village respectively have rather curvaceous figures, especially the latter.
Cool Mask: All Kakushi wear a cloth on their face that obscures everything but their eyes.
Crush Blush: A female Kakushi that accompanies Tanjiro to the Swordsmith Village gains a crush on Tanjiro and begins blushing as well as emitting hearts.
Extreme Doormat: They are total suck-ups to the Hashira, mostly out of fear.
The Medic: One of the Kakushi's duties is to give first-aid to wounded demon slayers following a battle, and become their aids if they are too injured to move on their own.
Servile Snarker: They sometimes make remarks at the other demon slayers and the Hashira's expense. Although regarding the latter, never to their face.
Support Party Member: Essentially their entire job.
Vague Age: Due to being masked, it's hard to decipher the Kakushi's ages, but it's likely that they are people in their late teens or early twenties, as Goto admits to being 23.

Goto

Voiced by: Makoto Furukawa (Japanese), Derek Stephen Prince (English)^{Other VA}

A member of the Kakushi, the clean-up brigade of the Demon Slayers.

Big Damn Heroes: It's implied that he was among the Kakushi who helped assist the Demon Slayers in preventing Muzan from escaping.
Breaking the Fourth Wall: In Someone's Dream, he notably addresses the audience directly, and introduces himself, Hetalia-style.
Car Fu: Implied that he was among the Kakushi who drove the cars in the city to ram into Muzan's giant baby form to slow him down.
Cool Mask: Wears a long mask, which covers his face and leaves an opening for his eyes, similar to a ninja's mask.
Deadpan Snarker: Arguably his main character trait. He especially fits this trope in regards to his opinions on Inosuke.
Nice Guy: He's a very docile and gentle individual. He has a deep respect for Tanjiro, Nezuko, Zenitsu, and Inosuke because of their bravery and capability. He even visits Tanjiro after the swordsmith incident to check on his condition and his progress. He also shows concern and relief after hearing that Nezuko can walk in sunlight and speak words again.
Not So Above It All: He is annoyed when stumbling upon a vase that Kanao dropped and broke, but decides to drop the subject as Kanao is technically his superior. When upon learning that Tanjiro awoke from his 2 month long coma however, he loses his composure and angrily yells at Kanao for not making more of a scene when finding out.
Older Than They Look: It's hard to tell with his uniform, but Goto is actually a 23 year old man.
Only Sane Man: He is always the sane one in the weird situations he ends up in. When Kanao was talking to Tanjiro, who had woken up from his injuries, Goto scolds Kanao for not informing the others that Tanjiro woke up (although this was because she still needed her coin to make decisions). And while Tanjiro is recovering in the Butterfly Estate after the swordsmith incident, Goto has to deal with the commotion caused by Hotaru and Inosuke (Hotaru threatening Tanjiro about his swords as usual, and Inosuke suddenly bursting through the window just to tell him about their next training with The Hashira).
To Hell and Back: He temporarily goes to hell to interview various demons on their opinions on the breathing style that slayed them, or even just the demon slayer that killed them. It turns out he just tripped and hit his head on rocks, and he was very angry that he ended up in hell when he blacked out.
Undying Loyalty: He's shown to have great loyalty and respect for Shinobu.

Masao Maeda

A member of the Kakushi and also the head uniform maker for the Demon Slayers.

Adapted Out: Due to being a character exclusive to extra pages of the manga and not the main chapters, he is nowhere to be seen in the anime, and it's unknown if he will appear.
All Men Are Perverts: Oh he's definitely a pervert big time. In fact, he was the one repsonsible for making the Stripperific Demon Slayer uniform for Mitsuri. He made some for Shinobu and Kanao too, but Shinobu immediately burned those uniforms right in front of him.
Butt-Monkey: No one respects this guy. And for good reason too because he's a massive pervert. His reputation is so bad that he even called the attention of Shinobu and Sanemi, who both gave him a good scolding for his behavior.
Embarrassing Nickname: His bad reputation in being suspiciously perverted, by tailoring sexualized female slayer uniforms, earned Masao the nickname of Scum Glasses among the female slayers.
Nerd Glasses: He wears a pair of round glasses to help him see.

Kasugai Crows are crows that are used by the Demon Slayer Corps primarily for communication.

Adaptation Expansion: Kyojuro's crow, Kaname, crying for his master's death is added in the Mugen Train movie, the manga didn't have that particular emotional response despite a cover art showing Kyojuro petting him, showing they were close.

- Sanemi Shinazugawa: Sourai
- Kyojuro Rengoku: Kaname
- Shinobu Kocho: En
- Muichiro Tokito: Ginko
- Tengen Uzui: Nijimaru
Awesome Mc Cool Name: Most of the Kasugai Crows in the series are named by their owners, and as such they have simple pet names; Tanjiro's crow on the other hand is too much of a prideful and independent crow to be like the others, the bird named himself Matsuemon Tennouji; in Japanese that is an extremely pompous name for a human, as if they were an important figurehead from a Samurai family or a noble from years past, but a crow wants to be called that, making it even more ludicrous among his crow mates who don’t buy into Matsuemon’s pride, his own master Tanjiro never called his name on-screen.
Bunny-Ears Lawyer: The first few crows shown are quite standard looking, devoid of any unique characteristic, however as the series progresses more quirky crows are introduced, sadly they are mostly reserved to only appear in manga volume extra illustrations.
- Inosuke's crow has a funny hairdo with three long hair strands.
- Muichirou’s crow is female and is pretty much his number one fan, always singing his praises and demanding others to worship him as well.
- Tengen's crow styles himself after his owner, just as flamboyant.
- Mitsuri's crow is always blushing and thinking about romance.
- Kagaya's crow seems to be a cut above the rest, he speaks extremely well as if he was human, and is highly intelligent, actually doing intel work of his own, instead of just relaying messages like other crows.
- Giyu's crow is apparently super old, always acting like an absent minded elder.
Clingy Jealous Girl: Ginko. Muichiro apparently can’t have any pets as she’d wind up getting jealous.
Non-Action Guy: They aren't used for fighting demons and they are only used for communication.
Talking Animal: The Kasugai Crows are capable of human speech, and can communicate with Demon Slayers. Truth in Television, since crows can be taught to mimic human speech much like parrots can.
Tsundere: Tanjiro’s crow of all things, it always acts bossy towards Tanjiro, even pecking him a lot, and sees Tanjiro as his subordinate, but it will not tolerate other crows not showing proper respect towards Tanjiro, seen when Muichiro’s crow thought Tanjiro was a lesser demon slayer and his crow immediately picked an argument with her.

Ukogi (Chuntaro)

Voiced by: Manaka Iwami (Japanese), Abby Trott (English)^{Other VA}

Zenitsu's Kasugai Crow, who is actually a sparrow.

Adaptation Expansion: Every slayer has their own messenger crow, some with unique designs even, but only Tanjiro’s crow gets any form of presence in the anime and manga, even if it's just to deliver a message before going away. Zenitsu’s messenger on the other hand is already different from the get-go, since it's a sparrow and not a crow. The little bird is referred by name to make it unique, while the others are only named in Databook trivia, and the anime made sure to adapt even the extra manga volume illustrations into full anime scenes, giving Ukogi more exposure than it already had in the manga proper, which in turn was more than any other crow, as if Ukogi is being pushed as a mascot of sorts.
Blunt "Yes": When Zenitsu's moping about himself falling behind Tanjiro in the Rehabilitation Training arc.
Zenitsu: It must be because I'm a lost cause, isn't it?
Ukogi: (chirps)
Zenitsu: Did you...just agree with me? How can you be so cruel? Would it kill you to say something like "you're doing your best" even just this once?
Dark and Troubled Past: In a little extra trivia in the first databook, it is revealed that Ukogi's parents were killed by demons, showing that he actually enrolled in the Demon Slayer Corps as a Kasugai crow, he wasn’t raised for the task like the other crows, explaining why there’s a sparrow amongst a group of crows at all.
Head Pet: He is always seen on top of Zenitsu's head during missions or free time.
Trademark Favorite Food: Ukogi. He enjoys eating ukogi since that's what he got his name from.
The Unintelligible: In the setting, messenger crows assigned to slayers have been taught how to speak human language. Zenitsu’s messenger, however, is a sparrow that cannot speak normally. He tries to communicate by just repeating “chu, chu, chu” over and over again accompanied by gestures. The narrator text will sometimes translate for the audience what the bird is trying to say, but Zenitsu will remain lost on what Ukogi is saying. Tanjiro on the other hand can understand the bird perfectly.

Kaburamaru

Voiced by: N/A

An intelligent white snake and Obanai Iguro's companion.

Feather Boa Constrictor: Although obviously not used as a fashion accessory, Kaburamaru can usually be seen coiled around Obanai's neck.
Funny Background Event: In an eye-catcher for "Love Hashira: Mitsuri Kanroji", the snake has cartoonishly bulbous eyes while he watches Mitsuri scarf down absurd amounts of food in astonishment.
Get a Hold of Yourself, Man!: When Obanai first met Mitsuri, he was so enamored and dumbfounded that Kaburamaru panicked and bit him to resuscitate him.
Loyal Animal Companion: He is this to Obanai and never leaves his side. After his death, Kaburamaru becomes this to Kanao.
Only Friend: Before joining the Demon Slayer corps, he was the only living thing that Obanai truly trusted.
Precocious Crush: A manga extra seems to imply he has one on Shinobu.
Single Tear: Sheds one during Obanai's and Mitsuri's deaths.
Snakes Are Sinister: Averted. He has a bit of an attitude, but is Obanai's loyal companion.
Wise Serpent: Apart from being particularly intelligent for a snake, he also helps Obanai fight Muzan after his eyes are destroyed by being his seeing-eye snake.
Undying Loyalty: Kaburamaru is greatly loyal to his master and friend, Obanai. He is even saddened by his demise, as he sheds a single tear for both him and Mitsuri.

Shino Buff Mice are intelligent mice that work for Tengen Uzui.

Non-Action Guy: They are capable of assisting Tengen and his acquaintances, but they don’t fight demons.

Sabito (above) and Makomo (below)

Sabito: "I will Make you never Forget the Secret Techniques Urokodaki has taught you."

A pair of mysterious children Tanjiro meets while training for the Final Selection.

The Ace: Sabito was by all accounts a talented swordsman who was able to kill most of the demons, resulting in all of the others besides him surviving the selection. This is the real reason Giyu doubts his abilities as a Hashira, thinking Sabito would have been far better had he survived.
Critical Hesitation Blunder: When Makomo fought the Hand Demon during her Final Selection, he gleefully revealed how many of Urokodaki's previous students he'd eaten. This stunned and horrified Makomo long enough for the Hand Demon to kill and eat her.
Cruel and Unusual Death: Makomo has her arms and legs ripped apart and killed by the Hand Demon, while the anime shows through a Gory Discretion Shot that Sabito had his head crushed by the same demon.
Cruel to Be Kind: Sabito has a habit of acting harsh toward others to goad them into doing what they need to. This includes taunting Tanjiro about his weakness to get him to cut through the boulder, as well as threatening to break off his friendship with Giyu if the latter doesn't get over his Survivor Guilt regarding his sister.
Dead All Along: Though Tanjiro is able to see and interact with them, it turns out that they've actually been dead for several years, having both been killed by the Hand Demon during the Final Selection. Tanjiro discovers later that Sabito would have been the same age as Giyu had he survived.
Fragile Speedster: The vengeful demon described Makomo as being weak but very fast.
Flowers of Femininity: Makomo has blue flowers on her mask, as well as pink ones on her kimono.
Get A Hold Of Yourself Man: In the past, Sabito punched Giyu after he was feeling survivor's guilt and convinced him to not give up living after Giyu's big sister saved his life. Giyu mentions that he can still feel the pain from Sabito's punch and realized that he cannot give up his role as a Hashira for the sake of his big sister and Sabito.
Heroic Sacrifice: Sabito saved everyone in his selection and was the only one who died.
I Coulda Been a Contender!: Sabito was a highly skilled swordsman who Giyu believes could have even become a Hashira stronger than him. However, he sacrificed himself during the Final Selection so everyone else could pass.
Parental Abandonment: They were orphaned and raised by Urokodaki, though at different times.
Pink Means Feminine: Makomo's kimono is pink, and patterned with darker pink flowers.
The Reveal: They are in fact ghosts of students that had failed the final selection. Urokodaki was quite surprised when Tanjiro casually mentioned them, wondering how he knew the names of his dead disciples.
Small Role, Big Impact: Sabito saved Giyu when they took the Final Selection together, an action that allowed Giyu to survive and encounter Tanjiro, allowing him to become a Demon Hunter in turn. Then Sabito and Makomo trained Tanjiro when he got stuck and unable to progress with his training, making them indirectly the cause of the demon's downfall. Despite their contributions to the plot, they make very few appearances afterwards due to the reveal that they were both Dead All Along.
Spirit Advisor: They both show up when Tanjiro is training for the Final Selection to help him train and offer them advice. However, the trope isn't really in effect until the reveal that they were actually Dead All Along.
Unfinished Business: After dying, they remain as ghosts along with Urokodaki's other slain students, in hopes that Urokodaki's next student will finally be able to defeat the Hand Demon that killed them. They help Tanjiro train for the Final Selection, and once he beats the Hand Demon, they are able to depart.
What Could Have Been: In-universe example. Tanjiro imagined what Sabito would have currently looked like had he survived the selection. He pictured an older looking Sabito in full uniform and said that he would have been a great swordsman alongside with Giyu.

https://static.tvtropes.org/pmwiki/pub/images/uzui_wives_anime_official.png

Top to bottom: Suma, Makio and Hinatsuru

Three female Kunoichi Demon Slayers and the wives of Tengen Uzui. With only complementary fighting abilities, they mostly supported their husband Tengen in his missions, sometimes with intel gathering.

As a group

Baby Factory: What all of three of them were raised as. Their ninja clan saw the kunoichi as nothing but disposable pieces for making children to expand the clan, and when needed they were expected to sacrifice themselves to gather intel. However, fate smiled upon them as they were paired with a husband that actually valued their lives as people. Tengen flat out told them that happiness and preserving their lives is a priority, and he hasn't forced any children upon the girls, preferring to let heirs happen naturally whenever they feel it's the right time.
Babies Ever After: Foretold. as Uzui and his wives intend to have a family, but only when the time comes. The epilogue shows this to be true, as Uzui has many grandchildren, the second Databook states Tengen’s first baby was born just a little while after Muzan’s defeat, he invited Giyu to see his growing family but which wife got pregnant first isn’t said.
Balanced Harem: Uzui treats all of his wives as equals while spending time with them all as much as he can, having never favored one over the other. It's part of the reason they are all perfectly fine sharing him because they get along so well with each other.
Color-Coded Characters: Downplayed due to not being as identical as the Butterfly girls, but Tengen wives are associated with a particular color. Hinatsuru purple, Makio red and gold, and Suma blue.
Comic Trio: They operate as this at times
Damsel in Distress: Tengen lost contact with his three wives on a demon slaying mission, Suma and Makio in particular were captured by Daki herself, forcing Uzui to recruit the main characters in order to find and rescue them.
Distaff Counterpart: The three wives are curiously similar to the main male lead characters: Tanjiro, Zenitsu and Inosuke regarding their basic personality traits; Hinatsuru is the peace maker and heart of the trio, like Tanjiro is, Suma is the overly emotional roller-coaster who cries and screams in fear a bit too much, like Zenitsu does, then comes Makio who is brash and gutsy and who’s always bickering with Suma, just like how Inosuke interacts with Zenitsu. The similarities are so obvious that several fan works do not let these similarities pass by unnoticed.
Happily Married: All three are very happy with Tengen, who cares for all of them equally.
The Infiltration: They infiltrate the Yoshiwara Red Light District as High-Class Call Girls in order to gather information on reports of a demon due to many unexplained disappearances.
Like an Old Married Couple: Makio and Suma
Ms. Fanservice: All of them wear very revealing outfits in their debut arc. They are dressed more modestly in later appearances, though they all still display a lot of cleavage.
Ninja: All three of them are ninja, and along with Uzui they're some of the few that are still left.
Perfectly Arranged Marriage: Makio and Hinatsuru were arranged to marry Uzui. They both love him very much and he loves them.
Poisoned Weapon: They all wield kunai that have been coated in wisteria poison.
Polyamory: All three of them are married to Uzui, since they're from a ninja clan where polyamory is considered normal. According to the second Databook Suma's sister was actually Tengen’s first promised wife, but Suma wanted to prove she loved Tengen more, with that she crashed her sister's interview, winning Tengen's favor instead. Eventually Hinatsuru and Makio were married off to him as well and Suma supported the idea.
Red Oni, Blue Oni: Makio and Suma are the loud and expressive Red Onis to Hinatsuru's composed and graceful Blue Oni
Similar Squad: Their personalities mimic the three boys. Suma cries a lot and thinks she is bad at fighting, like Zenitsu, Makio is fierce and hot-tempered, like Inosuke, and Hinatsuru is mature and level-headed, like Tanjiro (and is a traditional beauty like pre-demon Nezuko).
Single Woman Seeks Good Man: All of them love Tengen deeply as their husband because he cares more for their happiness and lives over anything and because he's such a Nice Guy to them.
The Three Faces of Eve: Suma is the child that is emotional, Hinatsuru is the wife who is mature and supportive, and Makio is the seductress who is brash and the most aggressive in her advances.
Town Girls: The fiery and confrontational Makio is the Butch, the elegant and diplomatic Hinatsuru is the Femme, and the emotional and melodramatic Suma is Neither.
Vitriolic Best Buds: They're co-wives technically, Makio and Suma tend to operate as this

Hinatsuru

https://static.tvtropes.org/pmwiki/pub/images/f1cd15f8_335c_465f_a9ab_5689ffa6e8c5.jpeg

Affectionate Nickname: Tengen called Hinatsuru as just "Hina" once, implying it is how he affectionally treats her, in the Upper-6 fight, however, Tengen called Hinatsuru by her full name whenever she was in danger.
Big Damn Heroes: She saves Tengen and Tanjiro at a critical moment during their fight with the Upper Rank-6, launching a Flechette Storm of wisteria-coated kunai at the demon and creating an opening for them to strike back.
Graceful Ladies Like Purple: She wears purple and her eyes are purple and she is very compassionate, nurturing and wise
Flechette Storm: She possesses several boxes that can conceal and launch dozens of poisoned kunai at an enemy. Even a single kunai hitting its target is enough to briefly affect an Upper Rank-level demon.
Mirror Character: Like Tanjiro, she is the calm and level-headed one who serves as an older sibling figure to the other two members of her trio.
Only Sane Woman: She is the one that tries to make keep the two other wives from fighting.
Proper Lady: She is very composed and ladylike compared to Makio and Suma
Purple Is Powerful: She has purple eyes and a purple kimono and she briefly helps out during the final fight against Daki and Gyutaro by unleashing wisteria-coated kunai at Gyutaro to weaken him.
The Stoic: Hinatsuru is a lot calmer than either Suma or Makio, who tend to be very emotional. One example is her reaction to Nezuko suddenly setting Tengen on fire to heal him; she only has her mouth open a little in surprise while Suma and Makio both freak out.
Team Mom: She is the eldest of Tengen's wives and the mature, motherly one who tries to calm down the other two when they start bickering.
Yamato Nadeshiko: She ticks all the boxes — beautiful, kind, poised, graceful and fulfills the "inner core of steel" requirement by being a capable fighter.

Suma

https://static.tvtropes.org/pmwiki/pub/images/0252eb9b_7a55_4c4a_9de7_3d3e43e5ab2b.jpeg

The Baby of the Bunch: She is the youngest of Tengen's three wives (though not by much, as she is 19 while Hinatsuru is 21 and Makio is 20) and the most childlike, being prone to crying fits and panic attacks.
Blue Is Calm: Inverted, Suma is very panicky, anxious and overemotional
Brainless Beauty: She comes off as incredibly silly and extremely emotive, but her time as a covert courtesan is shown to be very successful, it is commented by other Oirans that Suma was extremely popular, quickly becoming the main face of her house; which meant Daki quickly made Suma a target.
But Not Too Bi: The 2nd Databook states that Suma is bisexual, considering she is also revealed to be Tengen original's wife after winning against her older sister by crashing her marriage interview with Tengen, that comes in handy with she being very accepting of Hinatsuru and Makio being married off to Tengen as well, but other than that offhand revelation in a side-material Suma in the series proper is only shown to love her husband Tengen just like her companion wives do.
Butt-Monkey: Like Zenitsu, she is prone to crying in a silly, over-the-top manner, which usually makes Makio yell at and hit her, even resorting to stuffing rocks in her mouth at one point.
Child-Like Voice: Suma is 19, but has a noticeably high-pitched voice that makes her sound younger, but is congruent with her immature personality.
Cute, but Cacophonic: Although many see her as endearing, her constant crying and high-pitched voice can become a bit irritating where prolonged.
Hidden Depths: Suma might be a crybaby and call herself good for nothing, but she is smarter, stronger and more gutsy than she gives herself credit for. She crashed her sister's interview to become Tengen's wife and ended up marrying him instead, she is a capable fighter like his other wives, and she is so successful as an undercover courtesan that she becomes the face of her house. When Nezuko sets a poisoned Tengen on fire to heal him, Makio and Hinatsuru are too shocked to react, but Suma is the only one whose reflexes kick in fast enough that she shoves Nezuko away in a misguided attempt to protect her husband.
Inelegant Blubbering: She is prone to this, with exaggerated expressions coupled with copious tears and snot.
Innocent Blue Eyes: She has light blue eyes to go along with her childish personality.
Mirror Character: Like Zenitsu, she cries a lot and panics in stressful situations, but is a capable fighter when push comes to shove. Her name also matches his last name, Agatsuma.
Prone to Tears: She frequently bursts into tears, which usually gets Makio to react violently toward her.
True Blue Femininity: Suma's eyes and kimono are blue, and she's fairly feminine
Womanchild: She is a young adult who frequently screams, cries and overreacts in certain situations, she also shows signs of naivety as well

Makio

https://static.tvtropes.org/pmwiki/pub/images/dbabcaa2_bc03_44bd_a545_0ac89d00eec6.jpeg

Berserk Button: Suma doing anything, from her panic attacks to eating too fast and loudly doting over Nezuko when visiting her and Tanjiro at the Butterfly Mansion
Big Sister Bully: While they're not related, her dynamic with Suma has elements of this trope, as Makio frequently gets mad at her or yells at her for being a crybaby. When she yells at Suma to shut up and tries to shove rocks in her mouth for interrupting Tengen's last words, Suma cries, "Makio's tormenting me!", sounding exactly like a little girl complaining to her parent about being bullied by her big sister.
Cross-Popping Veins: She gets those when she's mad at Suma.
Hair-Trigger Temper: She frequently yells at Suma for losing her head in crisis situations.
Jerk with a Heart of Gold: She can be brash and hotheaded, but she has a softer side, loves Tengen dearly and will fight to defend innocents without hesitation.
Kissing Cousins: The second Databook reveals Makio is actually related to Tengen, as she is his cousin.
Mirror Character: Like Inosuke, she's hot-tempered and gets aggressive at the slightest provocation, but has a heart of gold underneath.
Red Is Heroic: She wears red and is a helpful ally in taking down the Upper Six demons
Red Is Violent: Makio's kimono is red, and she is very combative, especially to Suma
Tomboyish Voice: Being the most aggressive of the trio, she has a fittingly gruff voice.

Swordsmith Village

As a Group

The people of the Swordsmith Village are responsible of forging swords for the Demon Slayer Corps to kill demons with.

The Blacksmith: They are very skilled at crafting and forging the swords for their clients.
Cool Mask: Everyone in the village has to wear a hyottoko mask in order to conceal their faces from outsiders.
Expressive Mask: Their masks show a variety of emotions based on how they feel.
Hidden Elf Village: The location of the Swordsmith Village is unknown, and they have kept their village a secret for good reason. Any outsider being escorted to or from the village has to wear a blindfold and earplugs (and nose plugs, if they have a particularly acute sense of smell) during the trip so they cannot discern the location of the village based on the surrounding area.

Tecchin Tecchi Kawahara

https://static.tvtropes.org/pmwiki/pub/images/kny_tecchin_anime.jpg

^{Click here to see his real face (spoiler)}

The elderly chief of the Swordsmith Village.

Asian Buck Teeth: A rare non-stereotypical example in anime. He is briefly shown unmasked while attempting to calm a young Haganezuka throwing a tantrum, reveling small rodent-like buck teeth and squinted eyes.
Dirty Old Man: After Mitsuri saved him from a Lower Rank, he thought he died and went to heaven since he was being hugged by a cute girl while coughing blood. This makes Mitsuri flutter, and she endearingly calls him a little pervert.
Gonk: Not the most appealing under the mask in stark contrast to his adopted son Hotaru.
Happily Adopted: According to Volume 14 extras, he raised Haganezuka after his parents abandoned him at the age of 2.
Miniature Senior Citizens: He is an absolutely tiny old man.
Stern Teacher: Likely fulfills this role along with being a parental substitute to Haganezuka. He makes it abundantly clear that if the swords Haganezuka make get damaged for whatever reason, nobody is at fault except him for creating a faulty weapon in the first place. This is made all the more convincing as the man who made Mitsuri's sword which has never been damaged throughout the entire series.

Hotaru Haganezuka

Voiced by: Daisuke Namikawa (Japanese), Robbie Daymond (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/haganezuka_kny.jpg

^{Click here to see his real face (spoiler)}

One of many swordsmiths who works for the Demon Slayer Corps.

Alliterative Name: Hotaru Haganezuka.
Ax-Crazy: Haganezuka has a highly volatile temper and has, on multiple occasions, chased Tanjiro with kitchen knives for hours after hearing he broke or lost yet another of his swords. It's actually the main reason Tanjiro is one of his very few clients.
Badass Normal: Possesses no fighting technique but is incredibly frightening and agile when angered, and took abuse from Gyokko who was trying to make him break his concentration on honing Yoriichi's sword.
Berserk Button: Anyone who damages or loses his swords makes him go into wild bouts of anger. Because of this, he doesn't have that many clients aside from Tanjiro.
The Blacksmith: He's a skilled swordsmith.
Bros Before Hoes: Though he often gets angry at Tanjiro, he's very loyal to him. In the third light novel, the woman he's matched with asks him to stop making swords. He firmly rejects her then and there, declaring his dedication to his work and to Tanjiro.
Butter Face: Averted. Though many fans thought he wouldn't look appealing under the mask (or at least expected he'd look old), he's actually rather youthful and handsome.
Celibate Eccentric Genius: He never shows any interest in women and is only devoted to his craft. While this wouldn't be much of a big deal, it is noticeable in the third light novel where Tecchin, Kozo, and Kotetsu attempt to set Hotaru up on a date, only for him to frankly reject his date when she tried to convince him to stop making swords.
Comedic Sociopathy: Haganezuka chasing after Tanjiro with a butcher knife every time the latter breaks or loses his swords is usually Played for Laughs.
Comfort Food: Whenever he's angry, he buys mitarashi dango to calm himself down.
Determinator: His focus is practically superhuman. When repairing Yoriichi's sword he was able to completely ignore all of Gyokko's attempts to break his concentration, even when Gyokko took out one of his eyes.
Did You Just Punch Out Cthulhu?: When Muichiro, a powerful Hashira who had just awoken his demon slayer mark and defeated an Upper Rank, lends Tanjiro Yoriichi's old sword in order to defeat Hantengu who is actually Urami. Haganezuka grabs him by the neck and angrily tells him that he wasn't finished honing the sword. When Tanjiro takes the sword and runs, he smacks him on the head.
Early Personality Signs: He had his explosive temper even at 2 years old, which caused his parents to abandon him.
Embarrassing First Name: He considers his first name too cutesy, since it means "firefly."
Establishing Character Moment: Haganezuka first appears to deliver Tanjiro's katana, but instead of accepting Tanjiro's invitation to come into Urokadaki's abode, he ignores Tanjiro to explain about Nichirin Swords and how they're made, then gets excited when he notices Tanjiro has red eyes and hair because a child with those traits will likely have their sword change to a bright red color. When Tanjiro's sword turns black instead, Haganezuka throws a tantrum and throttles Tanjiro, all the while answering Tanjiro's question about his age like this choice of action is perfectly acceptable for a man like him to do. This all establishes Haganezuka's atrocious social skills, childish obsession with Nichirin Blades, and his bad temper.
Exact Eavesdropping: He secretly was nearby when Tanjiro was confronting Muichiro, listening to Tanjiro state how the swordsmiths are important to the Demon Slayers. Hearing these words made him willingly go through training and use dangerous smithing techniques in order to forge a strong sword for Tanjiro.
Eye Scream: He lost his left eye from Upper Rank 5 Gyokko in the middle of the swordsmith village raid.
Fluffy the Terrible: Haganezuka is a very scary swordsmith who will fly into a comically explosive rage if one of his swords is damaged. But when Tanjiro learns his first name (Hotaru, which means "firefly"), he thinks it's a cute name.
Hair-Trigger Temper: Every time Tanjiro breaks/damages/loses his sword, Haganezuka chases him with knives for several hours. Because of these actions and his bad attitude in general, he doesn't have many clients aside from Tanjiro.
Heroic Build: During the beginning of the Swordsmith Village Arc, he is reported missing and Tanjiro is unable to find him. When he finally appears, he is positively yoked, having spent weeks putting himself through Training from Hell in the mountains in order to forge the perfect blade for Tanjiro. This is Played for Laughs, but it later saves his life after Gyokko finds him working on the sword and attempts to break his will by torturing him. It is unlikely he would have survived all the punishment for as long as he did if his physical constitution wasn't so durable thanks to his training.
Hypocritical Humor: Haganezuka regularly attacks Tanjiro when he breaks/loses the swords he builds, not because he's actually mad at Tanjiro, but because he's frustrated at himself and his craft not being good enough for the occupational hazards Tanjiro has to go through. As Chief Tecchin states, the standard of the village swordsmithing is that the swords for the Demon Slayers must never break.
I'll Kill You!: Outright states it and attempts it on multiple occasions with a kitchen knife in hand to Tanjiro for snapping, losing, or chipping his sword in battle.
Jerk with a Heart of Gold: He is easily angered when something happens to his swords, but he really does take his job as a swordsmith very seriously. Although Tanjiro breaks and loses some of his swords, at the end of the day he's willing to make new ones for Tanjiro to continue on fighting.
Large Ham: Haganezuka is a larger-than-life character when it comes to creating swords, using overly dramatic, flowery language to describe his craft and flying off the handle completely if he feels his work is disrespected in any way.
Manchild: Is 37 years old, but throws tantrums like a kid when it comes to swords and can be calmed down by rattling wind chimes at him like a toddler. The manga even sometimes points out his age when he gets pissed at Tanjiro.
Meaningful Name:
- "Hotaru" (螢) means "firefly," which may refer to the fire used to forge swords.
- The first character of his last name, hagane, literally reads as "steel" (鋼), the material he works with as a swordsmith.
Never My Fault: According to Chief Tecchin, the standard of the village swordsmithing is that the swords for the Demon Slayers must never break. If the sword is broken, then the swordsmith is at fault for not crafting a sword capable of withstanding the occupational hazards the Demon Slayers go through. But rather than admit this, Haganezuka always blames Tanjiro for being too weak to keep the sword from breaking.
No Social Skills: Kotetsu brutally comments that his social skills are terrible, and it's not a wrong observation considering he doesn't have many clients because of how unlikeable he is. It's also the reason why he's still single.
Older Than They Look: He's actually 37 years old, but his face exposed during the raid on the swordsmith village looks youthful.
Parental Abandonment: According to Volume 14 extras, he was abandoned by his parents at the age of 2 due to his violent temper, and he ends up being raised by the chief of the Swordsmith Village, Tecchikawahara.
Power Limiter: Played for Laughs. Haganezuka's hat is strung with wind chimes that calm him down when they're rattled, so he takes it off whenever he wants to unleash his rage at whoever is making him angry, usually Tanjiro.
Psycho Knife Nut: Every time Tanjiro breaks or loses his sword, Haganezuka chases him with knives in both hands for several hours while screaming "I'll Kill You!" It's because of of this insane and violent nature that prevents him from having that many clients.
Running Gag: Getting furious at Tanjiro for breaking or losing his precious swords and chasing him with knives for hours.
Silly Walk: When Tecchin summons him after he spots the irate swordsmith sulking over Tanjiro using Yoriichi's sword to slay Hantengu without letting him finish honing it, he walks in a goofy manner swinging his body from side to side.
Skewed Priorities:
- Being attacked by an Upper Rank while he's at work restoring Yoriichi's blade? Nah, ignore the enemy, this is priority. Ironically, this actually works in his favor, as said Upper Rank Gyokko sees himself as an artist, and while he can easily kill him, being ignored by him makes him want to capture his attention before killing him.
- In addition, he also does not react when Gyokko contemplates murdering Kanamori and simply goes back to honing his sword after temporarily stopping when Gyokko destroyed the shed he was in with his Blood Demon Art.
- An upper moon is escaping and the only demon slayer in fighting condition present is unarmed? Who cares. If a Hashira takes the sword you were honing and lends to him? Strangle then hit him!
Strongly Worded Letter: After Tanjiro goes into a coma for two months following the fight with Daki & Gyutaro, Haganezuka can't come and beat him up for chipping his sword this time. So when Tanjiro wakes up and asks if he's received a new sword, the nurse girls deliver him a pile of very angry letters from Haganezuka that say, "I HATE YOU," "I CURSE YOU," and "I'LL NEVER FORGIVE YOU."
Surprisingly Realistic Outcome: Because of his explosive temper, he doesn't have many clients despite being one of the best swordsmiths. Tanjiro is one of the few Demon Slayers patient enough to keep coming back to him. His ballistic temperament possibly didn’t do any favors in one day having a family, several minor characters like him are shown to have descendants in the Epilogue and extra notes properly detailing their existence; Haganezuka isn’t shown or confirmed to have any.
Trademark Favorite Food: Mitarashi dango, a kind of rice dumpling on a skewer. When he gets a bad temper, he always buys his favorite food to calm himself down according to the Volume 8 extras.
Tsundere: He actually respects Tanjiro very much, in the Swordsmith Village arc after he overheard Tanjiro praising his skills despite the claims of him and his smithing abilities to be trash, Haganezuka puts his life on the line to reforge Yoriichi’s blade for Tanjiro, remaining completely focused on working the blade even as Gyokko was trying to kill him.
What the Hell, Hero?: Although Played for Laughs, his prioritization of restoring Yorichii's blade over his own life, and the village in general is rather questionable.
With Friends Like These...: When Gyokko considers killing Kanamori in order to break Hotaru's concentration, he doesen't bat an eye, much to Kanamori's anger.
Won't Take "Yes" for an Answer: After Tanjiro defeats Hantengu with Yoriichi's half-restored blade, a furious Haganezuka starts chasing him around yet again, demanding to know if he broke the sword he was working so hard on and not listening to the swordsmith trying to tell him he has Yoriichi's sword in his hand.
Would Hurt a Child: Played for Laughs. When not threatening Tanjiro with various acts of violence for damaging his sword, he psychically assaults Tanjiro in various albeit comedic ways such as wrestling him and poking his cheek repeatedly. He also hits an injured Muichiro on the head after he lends Yoriichi's old sword that Hotaru hadn't finished honing and frequently menaces Kotetsu when he provokes him.

Kozo Kanamori

Voiced by: Eiji Takemoto (Japanese), Kyle Hebert (English)^{Other VA}

https://static.tvtropes.org/pmwiki/pub/images/kny_kanamori.jpg

^{Click here to see his real face (spoiler)}

A swordsmith affiliated with the Demon Slayer Corps.

Alliterative Name: Kozo Kanamori.
Berserk Button: He's normally a calm and polite man, but when Inosuke purposely chipped his swords, all rationality was thrown out the window.
Happily Married: To his wife, En Kanamori.
He Had a Name: Kanamori invokes this trope during his encounter with Upper Rank 5 Gyokko, as he recognizes each individual swordsmith that is part of the horrifying corpse sculpture that the demon presents.
Love at First Sight: According to Volume 14 extras, he fell in love with his wife five years ago when he was 21 years old.
Not So Above It All: Despite chiding Haganezuka for overreacting to Tanjiro breaking his katana, Kanamori goes absolutely apeshit over Inosuke chipping his own creation in front of his eyes, so much so that Tanjiro has to hold him back. Though in all fairness, he had a much more valid reason to go all Haganezuka at Inosuke, as the damage done to his sword was clearly deliberately self-inflicted.
Older Than They Look: He's really 26 years old.

Kotetsu

Voiced by: Ayumu Murase (Japanese), Jeannie Tirado (English)^{Other VA}

^{Click here to see his real face (spoiler)}

A ten-year-old smith.

Big Damn Heroes: He saves Muichiro's life by helping to break the water-prison that Gyokko had trapped him in, despite being assaulted by small fish demons while doing so. He nearly dies in the process but is saved once Muichiro fully breaks free.
Break the Cutie: Poor Kotesu goes through a lot. He is orphaned with no siblings with the sole responsibility of protecting a doll his ancentor made of Yorichii, is slapped and insulted by Muichiro Tokito after he refused to allow him to use the doll to train, breaks down in tears when the mist Hasira ends up breaking the doll, witnesses his uncle and neighbors be mutilated and presented as art, and is almost killed after being lacerated by one of Gyokko' fish monsters.
Brutal Honesty: A trait of his. He doesn't hesitate to point out that Haganezuka should have just told Tanjiro what he wanted to do with the sword instead of attempting to take it without explanation since it's a form of trust.
Bullying a Dragon: His bluntness and mouthy attitude extends to Haganezuka of all people. Unsurprisingly, he does not react well.
Drill Sergeant Nasty: His real personality. Sadness over his father's death made him temporarily timid.
Funny Background Event: When Tanjiro converses with Kozo Kanamori after the latter knocks out Haganezuka by tickling him, Kotetsu can be seen chucking peoples at Haganezuka's unconscious body.
Meaningful Name: Quite appropriately, he shares a name with a famous blacksmith: Nagasone Kotetsu, whose blades have been patronized (and attributed to) a number of legendary swordsmen.
Mouthy Kid: He's rather outspoken and blunt.
Pocket Protector: He was saved from a fatal wound to the solar plexus thanks to Rengoku's sword hilt he was carrying to put on Tanjiro's new blade once Haganezuka was finished restoring it.
Put on a Bus: He's isn't seen after the swordsmith arc, implying that he traveled along with the rest of the villagers to find a new location to resettle everything. He comes back along with the other swordsmiths to visit Tanjiro and everyone one last time.
Small Role, Big Impact: He is a relatively minor supporting character that only appears in one arc, but his actions, such as helping Tanjiro discover the blade for his ultimate sword or saving Muichiro's life, play a huge role in making many of the Demon Slayers' future victories possible.
Took a Level in Kindness: From Muichirou's flashback, Kotetsu is briefly shown to be in a happier state, so it's safe to say that he's cooled down after the swordsmith arc.
Training from Hell: Puts Tanjiro through a week without food, water, or sleep. While it does actually work in having Tanjiro learn to predict attacks, he only survived during this period by drinking raindrops. The Narrator points out that Kotetsu's training is so hellish because he is too young to understand the limits of the human body (such as a human only being able to go three days without water).

Tetsuido

Voiced by: Atsushi Ono (Japanese), John Eric Bentley (English)^{Other VA}

Muichiro Tokito's former swordsmith.

Cool Mask: Typical of a swordsmith, although it's lifted so he can smoke and covers his eyes.
Cool Old Guy: A talented swordsmith who forged Muichiro's blade and a understanding mentor to his client.
Deadpan Snarker: After admitting that he doesn't have much time to live, he snarks that he doesn't care that much about staying alive at his old age.
Dub Personality Change: A minor example where the English dub removes the aforementioned jab at his age, removing his Deadpan Snarker side.
Eyes Out of Sight: His mask covers his eyes.
Posthumous Character: He passed away an unspecified time ago, due to a heart attack.
Reasonable Authority Figure: Despite technically serving Muichiro, he sees through his stoic façade, and is completely understanding of the boys trauma, urging him to not take these burdens alone.
Smoking Is Cool: Smokes a pipe, adding on to his wise personality.

Demon Associates

Nezuko Kamado

Tanjiro's younger sister, who was turned into a demon by Muzan Kibutsuji. She joins the Demon Slayers and fights Demons alongside her elder brother.

See here for all tropes regarding her.

Tamayo

Voiced by: Maaya Sakamoto (Japanese), Laura Post (English)^{Other VA}
Live actor: Mimi Maihane (Stage Play)

"You still use the term... the term "person"... to refer to even a transformed demon. And you're trying to save him. Allow me then, to lend you a hand."

A demon doctor in Asakusa who Tanjiro encounters. She helps him try to cure Nezuko.

Absurdly Youthful Mother: She is revealed to have had children prior to becoming a demon, and given that she is described as being physically 19, she likely had them while she was in her late teens.
Androcles' Lion: In a sense. Yoriichi spared Tamayo's life after she was freed from Muzan's control at the cost of being exiled from the Demon Slayer Corps. Centuries later, Tamayo helps develop the drugs that allow the Demon Slayer Corps to finally end Muzan for good.
Arc Hero: She serves as one of the main characters of the Asakusa Arc, alongside with her assistant, Yushiro.
The Atoner: It's revealed that Tamayo ate her family after being turned into a demon and ate other humans in her despair afterward, which she clearly regrets doing in present-day and works to live peacefully with humans... and why she's perfectly willing to kill herself to end Muzan.
Badass Boast: She gives a very nice one about how she and the Demon Slayer corps plan to kill Muzan no matter what.
Tamayo: I don't have to be stronger than you if I can make you weaker. Just as you will do anything to live, we will do anything to kill you.
Batman Gambit: When she injected Muzan with the perfect cure for demonism, she was fully expecting him to be able to disolve it. Albeit incapacitated for some hours by it, Muzan emerges victorious from the drug and gloats in her despaired face as he kills her. Except that it was all an act by Tamayo to make him think that the drug only did that. By the time Muzan realizes there are other effects, it is in the middle of the Final Battle and he can't stop to dissolve them, which in the end spells his doom.
Beware of the Nice Ones: She attacks Muzan directly with her newly-developed drugs and the Demon Blood Art of one of her patients, because Muzan turned her into a demon and purposely didn't warn her about her needing to eat humans, resulting in her eating her own family.
Big Good: Alongside Kagaya, Tamayo is the main force of opposition against Muzan, and in fact the key "quest" that Tanjiro works around is about collecting blood samples from demons for her to study and develop a cure for demonism. Fittingly, she and Kagaya are the ones who orchestrate Muzan's final downfall, with complete success. Kagaya's efforts are centered around creating the situation to bring him down and providing military support in the form of his corps, while Tamayo' efforts are the thing that actually make it possible for Kagaya's organization to gain an edge (turning them from Badass Normal to Empowered Badass Normal that can withstand the harmful effects of blatantly supernatural Demon Blood Arts) into defeating Muzan's henchmen and ultimately kill the man himself. They may be the first casualties of the Final Battle, but they certainly have the last laugh.
Broken Tears: After breaking free from Muzan thanks to Yoriichi, she sheds these before they evolve into Berserker Tears as she declares her hatred towards her former master and tormentor.
Crazy-Prepared: The medicine she and Shinobu used to try to make Muzan human again had three other medicines mixed in it, all in order to make sure that Muzan was defeatable. One of them causes rapid aging, which eventually starts slowing him down, another one stops him from trying to divide himself to escape, and the last one starts to destroy his cells. She also created many more, which is pivotal to save a demon-possessed Tanjiro and finally break him free from Muzan's clutches.
Dark and Troubled Past: When she was a human being, Lady Tamayo fell ill with a life-threatening disease at the age of 19 and searched for a cure. She then came across Muzan Kibutsuji, who offered her a way to treat her illness. She foolishly agreed and as a result, became a demon, which caused her to committing a murderous rampage around her hometown, killing her husband and their children, as well as a number of innocent civilians. When she found out what she did, she was horrified and fell into despair. She then became an unwilling servant to Muzan, having no hope that the Demon King could be defeated.
Damsel in Distress: Tamayo is trapped in a cocoon created by Muzan's flesh after trying to use the medicine to turn him human. Sadly, no one is able to save her and she is killed by Muzan once he recovers, but not after she injected her Magic Antidote on him that lead to his long and painful degeneration and eventual death.
Defiant to the End: She tells Muzan to go to hell and demands her family back. Even when she is summoned by him later to demand what she had done to him, she tells him off and says to use his multiple brains to figure it out. When he realizes he can't escape by dividing himself, she comes back to tease him about it and the fact that she also put another substance in the medicine to cause cell destruction.
Emotion Control: Her Demon Blood Art is capable of emotional manipulation via creating certain scents.
Eye Scream: After getting close to Muzan in order to inject him with the demon-curing medicine, he gouges out her left eye with his finger and keeps it lodged in her head while he enters his flesh cocoon to recover.
Gone Horribly Wrong: Spectacularly subverted. Her attempt to turn Muzan back into a human by injecting him with a demon-curing drug backfires horribly, as it instead empowers Muzan to an even greater degree once he heals in his flesh cocoon. Tamayo seems to be in despair later on as he kills her, but halfways through the Final Battle it's shown that it was all an act to lure Muzan into a sense of security, as the drug had several additional effects specifically readied to further weaken him and remove his abilities in the event that he could dissolve the primary component.
Good Eyes, Evil Eyes: Much later into the series it is show Tamayo’s eyes used to look more like those of a fierce demon, when she still was bound to Muzan’s will; after she breaks free from Muzan's curse her eyes become more similar to that of a human, although with a very sad expression. But when she faces her tormentor once more, they return to its fierce form, signifying how she despises him and how she wants him gone.
Heel–Face Turn: Long ago, Tamayo was a vicious demon who served Muzan after despair from killing her family led to her embracing her demonic nature. She has since repented and become a kind doctor who wishes to see Muzan fall. How she was able to break out of Muzan's control was with the help of Yoriichi. When he almost defeated Muzan, Muzan escaped, but his control over Tamayo broke, allowing her to regain her own free will again.
Horror Hunger: Tamayo originally became a demon in order to survive a fatal illness to see her children grow up... but unlike Nezuko, Tamayo ate her own family after turning and in her despair ate other humans before she began to atone for it.
Immortality Begins at Twenty: Almost. Although she can pass for younger, she is physically 19 years old, implying that she likely became a demon at that age.
Inconspicuous Immortal: Unlike the other demons who often lead extravagant, immortal lives and gleefully embrace their bloodthirst, she has no such wish, buying blood to sustain herself from willing donors. She lives quietly with Yushiro while working as a doctor, and the younger demon uses his powers to keep them hidden from Muzan.
Jerkass to One: While Lady Tamayo is a kindhearted demon, who's completely polite and kind towards others, her kindness does not extend to her mortal enemy, Muzan Kibutsuji, who she ultimately hates with passion, and rightly so.
Killed Off for Real: After Muzan returns to his true form, he proceeds to crush Tamayo's skull, ultimately killing her.
Laser-Guided Karma: Despite being one of the chief Big Goods of the series and playing the single most pivotal role in the final battle, Tamayo is still damned to enter hell alone for the atrocities she committed in the past after first becoming a demon. This is poignantly conveyed in the color spread for chapter 204, which shows all the heroic characters who died during the final arc happily walking together to the afterlife, while Tamayo is solemnly out-of-focus and alone in the background facing the opposite direction, showing that she is not going to the same place.
Magic Antidote: After doing research with Nezuko's blood and the blood of both the Lower and Upper Ranks, Tamayo was able to create a medicine that can instantly revert a demon back into a human state. A young man who got turned into a demon by Muzan in the early chapters instantly became human again thanks to the medicine and is shown to be tearfully embracing his wife. Now that the medicine is confirmed to work, Tamayo had given the medicine to Urokodaki to cure and change Nezuko back into a human to foil Muzan's plans, and had attempted to use the medicine on Muzan himself to turn him back into a human to try and finish him off once and for all. Unfortunately, Muzan is able to overcome the medicine because of the cocoon he's made and the stalling from his demons. Fortunately for the heroes, Tamayo and Shinobu's well-prepared to create another effect from the medicine that makes Muzan rapidly age... then avoid cell division, and finally to destroy them from within.
Never My Fault: Discussed. When they meet again, Tamayo is quick to blame Muzan for the deaths of her family, because he turned her into a demon and she ate them afterward. Muzan retorts that she has only herself to blame since she asked him to demonize her in the first place, which Tamayo can't deny.
Nice Girl: One of the few good-hearted demons in the series.
Not Quite Dead: Tamayo is seemingly killed by Muzan after he overcomes the effects of her drug, and what's left of her is absorbed into his body. However, her consciousness is able to persist within her absorbed cells and Muzan briefly communicates with her in his mind during the final battle, forming her cells into the shape of her head. She takes the opportunity to mock him for his ignorance about his Rapid Aging before Muzan disperses her and just reads her memories instead. Tamayo's physical body may be destroyed, but her mind is still around and doing whatever she can to impede Muzan.
Offing the Offspring: She killed her children upon her demonic transformation, to her horror and despair. The reason she even became a demon in the first place was to survive her illness and wanting to see her children grow up.
Perception Filter: Her Blood Art generates a mist that when breathed in will cause the victim to temporarily visual hallucinations. It can't be used to target specifically, which is why she didn't use it to help the Kamado siblings against the two demons hunting them down.
Prim and Proper Bun: She's a Yamato Nadeshiko with a neat bun in the back.
Raven Hair, Ivory Skin: She's frequently described by Yushiro as beautiful, with black hair and pale skin.
Really 700 Years Old: She's the second oldest character in the series, having been a demon already at Muzan's side almost 500 years ago, outdoing even the likes of Kokushibo and Akaza.
Sadist: It's not a regular facet of her character, but after Muzan consumes her, she takes unnerving pleasure in taunting him from within his mind as his body breaks down from her poison.
The Starscream: A rare sympathetic example, since she didn't want to be there and how she detests Muzan that she wants to get out and to kill him as well. She was apparently his right hand woman 500 years ago given that he kept her close to him, but she refused to help him when Yoriichi was cutting him down.
Tears of Joy: She breaks down in tears when Tanjiro tells her that Nezuko considers her and Yushiro humans, seeing that she has spent 500 years living in an unnatural monstrous state.
Token Heroic Orc: The first Demon who was freed from the curse of Kibutsuji. She continued to oppose him since, working as a doctor to aid humans.
Truth Serum: One application of her Demon Blood Art.
Vegetarian Vampire: Instead of devouring humans, she merely needs to drink their blood to survive, which she obtains by purchasing it from willing donors.
Yamato Nadeshiko: She's a gentle yet strong-willed Japanese woman in a floral-patterned kimono. She's frequently described by Yushiro as beautiful, with Raven Hair, Ivory Skin, and a petite build.
Your Head A-Splode: After Muzan overcomes her attempt to revert him to a human, he taunts her for her failure before crushing her head in an explosion of blood. But, it turns out she was absorbed through Muzan's hand and dwells inside his body.

Yushiro

Voiced by: Daiki Yamashita (Japanese), Kyle McCarley (English)^{Other VA}
Live actor: Hisanori Satō (Stage Play)

A young man who was turned into a demon by Tamayo.

Arc Hero: He serves as one of the main characters of the Asakusa Arc, alongside her master, Lady Tamayo.
Ascended Extra: He plays a prominent role in his introductory arc, but afterwards he only gets very sporadic, brief appearances. In the Infinity Castle Arc he plays a much bigger role, especially on the Final Battle.
Berserk Button: Just being in the general vicinity of Lady Tamayo is enough for him to want to murder you.
Big Damn Heroes: After Zenitsu defeats Kaigaku, Yushiro catches him before he falls to his death and gives him medical treatment. He gets another heroic moment when he stops Nakime from using her biwa to manipulate Muzan's castle in order to support Tanjiro, Giyu, Mitsuri, and Iguro.
Child-Like Voice: Yushiro seems to have been very young when Tamayo turned him into a demon, and he retains a boyish voice, as portrayed by Daiki Yamashita.
Competing with a Corpse: He's madly in love with Tamayo, but she doesn't accept his romantic feelings for her since she still hasn't gotten over her husband's and children's deaths.
Covert Pervert: While obsessive, his crush on Tamayo seems to be purely romantic. That is until episode eight's Taishō Era secret where Tanjiro reads his diary, in which he recounts the time Tamayo slipped on a step while deep in thought. The rest of the entry disturbs Tanjiro enough for him to decide to stop.
Deadpan Snarker: While he's healing Zenitsu, he snarks at the rookie Demon Slayers who were telling him to not be so negative about Zenitsu's injuries. Moments later, he tells them that they were being too loud and now called the attention of Muzan's lower demons. He also makes fun of Murata fighting the demons, sarcastically rooting for him and calling him "senpai", much to Murata's dismay.
Determinator: After Tamayo's death, it's heavily implied that Yushiro will follow her soon, but he still lives long enough to help the main characters and the Demon Slayer Corps against Muzan and the Twelve Kizuki, long enough to avenge Tamayo as well. Thankfully, its later shown he can keep on living without her, at least on a physical level, as its strongly implied he was planning to kill himself.
Driven to Suicide: Arguably. It's strongly implied that he plans on killing himself after the Final Battle, as Tamayo is dead. Tanjiro tries to talk him out of it, but Yushiro leaves without saying anything else, making his fate uncertain. He eventually overcomes his grief and dedicates his life to portraying Tamayo's beauty through painting.
Earn Your Happy Ending: The second fanbook hints that Tamayo will one day reincarnate after atoning for her sins in Hell, and by that point the demon blood within Yushiro will have thinned, allowing the two to live and die together as a normal couple.
Green-Eyed Monster: He is madly in love with Tamayo and hates anyone who gets close to her regardless of gender or age.
His Heart Will Go On: Never fell in love with another woman besides Tamayo after her death.
Jerk with a Heart of Gold: Quite rude towards anyone Tamayo doesn't know, but deep down, he's a good guy at heart. And he's willing to help anyone out for Tamayo's sake.
"Just Joking" Justification: He proposes that he and Tamayo flee and leave Tanjiro and Nezuko to fight the demons who'd tracked them down. When Tamayo is horrified, Yushiro quickly insists that he was kidding.
Last of His Kind: Following Muzan's final defeat and death, Yushiro and his cat Chachamaru become the last demons in the world, as they were the only demons not created by Muzan. He's still around even in modern times.
Let's Get Dangerous!: In chapter 182, Yushiro manages to sneak up on Nakime and uses his Blindfold Blood Art to block her vision, causing Muzan's Infinity Castle to start crumbling.
Loophole Abuse: Tamayo warns him that she won't tolerate him hitting Tanjiro. The next time Tanjiro offends Yushiro, Yushiro throws him, then points out that Tamayo didn't say anything about throwing Tanjiro. Tamayo points out that it isn't any better.
The Medic: He learned medicinal techniques from Tamayo and gives medical treatment to an injured Zenitsu.
Non-Action Guy: Although he's a demon, he's not one to do the fighting. Instead, he uses his talisman Demon Blood Arts to support his allies in battle and he uses medicinal knowledge and techniques. However, Tamayo has mentioned that he could enter combat mode after an unspecified amount of time. He finally does in chapter 182, where he stopped Nakime from manipulating Muzan's Infinity Castle and allowing Iguro and Mitsuri to join Tanjiro and Giyu.
Older Than They Look: Naturally for a demon. He is chronologically 35 years old, but passes for someone far younger, to the point he could easily blend in as a disguised Demon Slayer working with colleagues on their early 20’s like Murata. Although given that he's in his early teens in Kimetsu Gauken, he could be physically younger, it's hard to say since that world does shift the ages of a few characters.
Paper-Thin Disguise: When joining in the fight against Muzan, all Tamayo does to sneak Yushiro into the Demon Slayer group was change his eye design and give him the Demon Slayer uniform. Because he was turned into a demon by Tamayo, none of the other Demon Slayers figured out he was a demon, despite feeling something off about him and literally nobody knew his face when he joined in. So he really looks like he fits in with the group of rookies thanks to the uniform and eye change.
Perception Filter: His Blindfold Blood Art allows him to create talismans that block the scent and presence of objects, people and things. He uses this to fool Nakime's vision to stop her from manipulating the Infinity Castle and allow Iguro and Mitsuri to regroup with Tanjiro and Giyu.
Pet the Dog: Before Tanjiro's departure following Susamaru and Yahaba's defeat, he takes back his earlier insult to Nezuko and calls her a beauty.
"The Reason You Suck" Speech: He gives a rather dark insult towards a defeated Kaigaku before rescuing Zenitsu, saying how Kaigaku never received anything because he never gave anything and calling him pitiful to die alone. Considering that the receiver's quite an ass himself, it's a pretty nice send-off.
Reclusive Artist: As an In-Universe example, in the Distant Finale set in modern-day Tokyo, he became one, to the point that he would threaten anyone who would interview him with a rifle.
Rage Breaking Point: He absolutely snaps after Tamayo's death and does all he can to bring Muzan down by destroying the Infinity Castle.
Single-Target Sexuality: He only has eyes for Tamayo and he's not into anyone who isn't Tamayo. He goes as far as calling Nezuko ugly. After Tamayo's death, he never fell in love with anyone again and spent his entire life single.
Skewed Priorities: While regenerating, he's more pissed off at the fact his time with Tamayo is shortened by others... than the fact they're currently under attack.
Sole Survivor: As a demon, Yushiro outlives the entire cast in the modern era epilogue. Kiriya Ubuyashiki also lived to the modern era, but as a human mortal he will eventually die of old age leaving Yushiro as the only living proof that Tamayo and the Demon Slayer Corps ever existed.
Support Party Member: Albeit he has some combat ability, his utility based skills and ilusion talismans are the crux of his power. He especially leans on this role during the Infinity Castle arc, as he provides the Demon Slayer corps with his eye talismans, allowing Kiriya to oversee the entire operation and map the Castle. Also, when the final showdown with Muzan erupts at the end of the arc, Yushiro focuses on assisting fallen slayers and Hashira to allow them to rejoin the battle. This ends up being immensively important and one of the key factors of the victory as the Heroic Second Wind several of the Hashiras get thanks to this is key in finishing off Muzan, not to mention his eye talisman also allowed Iguro Obanai to continue fighting in spite of getting his eyes torn off.
Tears of Joy: Sheds them after Muzan's defeat.
Token Heroic Orc: One of the few morally-upstanding members of an otherwise Always Chaotic Evil race.
Tragic Keepsake: He kept Tamayo's hairpin as the last reminder of her after she was killed by Muzan.
Tsundere: He can be blunt and brash, but can also show a sweeter side to him, even if he denies it. He congratulates Tanjiro for overcoming his demon transformation back to human, but comically shuts down Tanjiro before leaving.
Vegetarian Vampire: Like Tamayo who turned him, he only needs a bit of blood to survive and doesn't need to hunt humans.
When He Smiles: Yushiro gives a warm smile when visiting Tanjiro at the Butterfly Estate one last time.
Your Head Asplode: During the fight with Yahaba and Susamaru, he ends up getting his head blown off by Susamaru's temari ball. Due to being a demon, he regrows it, though it takes a few minutes.

Chachamaru

A feline familiar that assists in Tamayo's medical research with Demon blood.

Ambiguous Gender: Chachamaru's gender is unknown.
- What doesn't help is that the "maru" suffix is used in Japanese male names, while also being a Calico cat (which are typically female, but there are cases of male calicos as well).
Big Damn Heroes: During the final battle against Muzan, it jumps in to save the Hashira as they begin succumbing to the effects to Muzan's cell-destroying blood, injecting them with an antidote that cures the poison and allows them to continue fighting.
Cats Have Nine Lives: Chachamaru invokes this trope, as the cat is seemingly slashed to pieces by Muzan but is able to survive and be reassembled by Yushiro. It's revealed that Yushiro had turned the cat into a demon some time prior.
Cute Kitten: Chachamaru is a pretty adorable little cat who's friendly enough to allow Tanjiro to pat its head.
Heroic Sacrifice: It jumps right into the thick of the battle with Muzan to save the poisoned Hashira despite getting injured in the destruction of the Infinity Castle, and gets swiftly cut apart by Muzan once he realizes what it's doing.
Kill the Cutie: Being an adorable cat doesn't save it from suffering a brutal death at Muzan's hands. Though it turns out to be Not Quite Dead.
Last of His Kind: Following Muzan's final defeat and death, Chachamaru and its owner Yushiro become the last demons in the world, as they were the only demons not created by Muzan. It's still around even in modern times.
Perception Filter: As a feline, it does not posses any magical powers. However, it does manage a spell of invisibility cast on it by Yushiro by meowing whenever it arrives to collect blood.
Undying Loyalty: Chachamaru is very loyal to Tamayo and later Yushiro after Tamayo's death.
