Kamado Family
Tanjuro Kamado
Tanjuro Kamado
Voiced by: Shin-ichiro Miki (Japanese), Kirk Thornton (English)Other VA
The father of Tanjiro Kamado and Nezuko Kamado and his other children and the husband of Kie Kamado.
- Ambiguous Situation: Tanjiro at first denies his father ever had a Demon Slayer Mark, stating all he had was a scar on his forehead, but Tanjiro retracts his own thoughts for a while, thinking Tanjuro may have a different layer on his scar if one looked hard enough; with that the fact Tanjuro may have had a Mark is open to speculation, the fact he actually knew the Transparent World technique, something only Marked individuals could achieve could be the confirmation that Tanjuro does have the Mark indeed.
- Art Evolution: In the manga, Tanjuro looks quite ghastly for the first time he is seen, in the flashback during the first time Hinokami Kagura is shown; much later in the series in another flashback during the Akaza fight, Tanjuro looks slightly less spent, as Gotoge's art has changed a little by then, where Tanjuro much looks closer to his son Tanjiro than before.
- Charles Atlas Superpower: Even while on the verge of being Nothing but Skin and Bones due to his illness, Tanjuro's mastery of the Hinokami Kagura allowed him to perform physical feats even a man in perfect condition shouldn't capable of, like performing his Dance of the Fire God in the snow for hours upon hours without getting tired.
- Happily Married: To Kie Kamado.
- Good Scars, Evil Scars: He has scar in the same place as his son, Tanjiro.
- Incurable Cough of Death: He died from an incurable disease a year ago before the start of the series.
- Lineage Comes from the Father: While it was rather easy to assume due the unmistakable physical resemblance and particular traits, the 2nd Databook confirmed Tanjuro as the one descending from Sumiyoshi and his children (although it isn't said from which one), thus being the one who received the legacy from his father, passing down the Hinokami Kagura to his son Tanjiro.
- Martial Pacifist: He's a very skilled fighter, but he tried to warn a dangerous bear to leave when it came to his area. It didn't heed his warning and was beheaded as a result.
- Nice Guy: He's a kind and gentle person who loves his family very much. Even when he has to fight a bear, he didn't show any hard feelings towards it and he even gives a prayer for it after he defeated it.
- Papa Wolf: He is very protective of his family as seen with his fight against a dangerous bear.
- Posthumous Character: By the time the story starts Tanjuro had already been dead for a year, felled by an unspecified illness, he however is the protagonist's father and seemed to have imparted some important life lessons and some techniques that prove to be pivotal in many events later in the story; with that his son Tanjiro recalls key moments in the past where his father Tanjuro taught him something, using that knowledge to slay the demons Tanjiro encounters throughout the series.
- Red Herring:
- Tanjuro has a large air of mystery about him and always appears to be more than he seemed, with it being heavily hinted that he had some kind of connection to the Demon Slayers at some point. However, whatever his was past before starting his family is never elaborated on.
- Throughout the series, there are brief flashbacks to a mysterious black haired swordsman with hanafuda earrings and a red mark on his forehead who often appears in scenes involving Tanjiro. Similarly, the hanafuda earrings that Tanjiro inherited from his father are repeatedly remarked to have some special significance to them. Late in the series, it's reveal that the black haired swordsman is actually Yoriichi Tsugikuni, who only by coincidence shares many of the same features as Tanjuro and Tanjiro. Likewise, the hanafuda earring belonged to Yoriichi as well, with him having gifted them to the Kamado family who made them into family heirlooms.
- Religious Bruiser: He was never a demon slayer, the Kamado family passed the Hinokami Kagura style generations down the line till it became a religious ceremony to them, Tanjuro specifically performed it on scheduled repetition as means to ward off evil spirits and bring good fortune to his family, it is just that Hinokami Kagura made him a person with superhuman prowess despite his ill and frail body.
- Spirit Advisor: His second most prominent role in the series other than the knowledge he passed onto Tanjiro in retrospect, as Tanjuro died 1 year before the story began; while other members of the Kamado family appear from beyond to guide Tanjiro and Nezuko, their father Tanjuro is the one who appears more: He is the one to guide Tanjiro out of Enmu's dream prison, and the one to guide Nezuko towards the final Muzan battle at the end of the series.

The mother of Tanjiro Kamado, Nezuko Kamado, and her other children and the wife of Tanjuro Kamado.

Sumiyoshi Kamado
Sumiyoshi Kamado
Voiced by: Hirofumi Nojima (Japanese), Howard Wang (English)Other VA
- All There in the Manual: How exactly Yoriichi and Sumiyoshi first met is not properly shown in the series beyond just stating Yoriichi saved him from a demon attack, it is the Sengoku Rumours at the 22nd Volume that make it clear. After being expelled from the Demon Slayer Corps, a broken Yoriichi went back to the house he lived with Uta, it was left abandoned for a while, there he met Sumiyoshi and Suyako who stationed there as the couple thought the house had no owner and Suyako was on her last month of pregnancy; the couple was being attacked by a demon, Yoriichi saves them and is befriended by the two, Yoriichi gave that house to the couple whom he saw as people who had a brighter future than his own.

Suyako was Sumiyoshi's wife and an ancestor to the Kamado Family.
- Accidental Hero: Suyako's innocent curiosity is the sole reason a secret legacy of Sun Breathing users started at all. Yoriichi at the lowest point of his life stopped teaching anyone about Breathing Styles, but Suyako saw his techniques as something beautiful to look at; with that every time Yoriichi performed his moves to entertain Suyako's request, Sumiyoshi took upon himself to learn all he could at the minute details with his photographic memory, feeling that he and his family should preserve Yoriichi's legacy even if the man in question had completely lost hope in himself.

- All There in the Manual: The second Databook clarifies Amane only got pregnant once, bearing quintuplets, it could be assumed since her children look so similar but in the story proper it is never brought up that they are quintuplets, and with some siblings being pointed out often that they are younger and older than the other it would be harder to assume they are just older/younger by mere minutes. It also revealed that her maiden name is Himorogi.

- Exotic Eye Designs: Amane's large purple eyes have the same unique spiraling design as her children.

- Together in Death: Since she refuses to leave her husband to die alone, she decides to die with him along with her elder daughters in an explosion to ensnare Muzan and bring in the Hashira to finish Muzan.

It's shown many times that Kyojuro still remembers his mother's advice after received a mortal wound and he recalled a last conversation he had with his mother shortly before she passed away. Talks about duties of born strong is to protect the weak not used as personal gain. or time Kyojuro battle against lower moon two, he recalled his mother's words remind him brief on Rengoku Family generations for slayer demon and she reminds Kyojuro he have power. It shows that Ruka have strong mind and view even she have weak body.
- Morality Pet: In a sense that without her presence, Shinjuro further spiraled intro depression and alcoholism, and became a chronically drunk and aggravated curmudgeon.

Senjuro Rengoku
Voiced by: Jun'ya Enoki (Japanese), Cedric L. Williams (English)Other VA
The younger brother of Kyojuro Rengoku and the son of Shinjuro Rengoku and Ruka.
- Antiquated Linguistics: While every other character calls their older siblings the typical "onii/onee-chan" or the like, Senjuro calls his brother "aniue". But considering the timing of the story, the term isn't too archaic.
- He also calls his father "chichiue", another old-fashioned term.
- Big Brother Worship: He loved his big brother very much and always admired him.
- The Dutiful Son: We never see any servants at the Rengoku estate. And between Shinjuro being drunk, and Kyojuro having Hashira duties, it seems Senjuro has been taking care of the house practically on his own.

Kyogo Shinazugawa
The husband of Shizu and biological father of Sanemi and Genya Shinazugawa.
- Abusive Parents: He would frequently hit (or try to hit) his own children, with Shizu constantly being forced to protect them from his violent outbursts.
- Alcoholic Parent: Per Genya's internal narration in "A Dream in the Moment" (fourth chapter of One-Winged Butterfly, second spin-off anthology light novel), Kyogo was described as having breath that "stinks of alcohol from morning until night", implying that his violent outbursts are a result of perpetual alcoholism.
- Ax-Crazy: He was very prone to violent outbursts, with both his wife Shizu and his children being the frequent targets of said outbursts, with him violently beating them, seemingly for no reason. His cruel and aggressive behavior even extended towards strangers, which ultimately resulted in him getting himself killed by one of the victims of his outbursts on the streets.
- Compliment Backfire: Near the end of the series, in the crossroad to the afterlife Kyogo violently pushes Sanemi away, barring him from staying with his mom Shizu and accompany her to hell, Kyogo praises Sanemi for being strong just like him so he should cling to life. That certainly isn't the comparison and praise Sanemi wanted to hear, as he and all his siblings disliked their abusive father.
- Crazy Jealous Guy: Implied to the point that he would sooner burn in Hell with his wife for eternity despite his despicable behavior in life giving absolutely nobody wanting anything to do with him, let alone feel any sort of love for the man.
- Cruel Mercy: He prevents Sanemi from succumbing from his injuries, but given that his son has to deal with the knowledge that his entire family is dead, and his mother is stuck in purgatory with Kyogo, it's far from a kind act.

- It Is Not Your Time: He's the one to tell his son Sanemi as much when he pushes him back toward the living world.
- Ironic Name: The first syllable of his name is represented by '恭' kanji that means "respectful, polite". He is anything but respectful or polite, being a violent man who lashed out at people seemingly for no reason.
- Jealous Parent: He shows shades of this. It's implied that part of the reason why he prevents Sanemi from staying with Shizu in the afterlife is so he can have Shizu all to himself in hell.

- Posthumous Character: He was killed when Sanemi was still a little kid.

- Born Unlucky: Married to a violent man, turned into demon, killed all but two of her children, and got killed by her eldest son. Even in the afterlife, she's trapped in a black purgatory with her abusive husband, although it's unclear whether it's the heavens punishing her for murdering her children, or out of her own volition due to guilt.

Tokito Family
Muichiro's Parents
Father voiced by: Noriaki Sugiyama (Japanese), Jalen K. Cassell (English)Other VA
Mother voiced by: Manami Numakura (Japanese), Cristina Valenzuela (English)Other VA
Dad Tokito above; Mom Tokito below.
Muichiro and Yuichiro Tokito's parents, a humble family of woodcutters living in the mountains, their twin children noted their parents to be very kind, Muichiro looked up to his father's kindness but Yuichiro took their kindness as overexerting themselves more than he thought they should, attributing their untimely deaths to their selfless nature.- Adaptation Expansion: As small as their roles in the manga, the anime expanded them; the mother actually has a line of dialogue, while she never spoke in the manga, and the father's trail for the medicinal flower is actually shown, the manga only mentioned he died looking for it.
- Lineage Comes from the Father: Left hanging, in the manga it couldn't be assumed which parent could be the descendant from Kokushibo, due the lack of color illustrations and enough details, and the 2nd Databook doesn't specify which parent came from that bloodline; the anime, however, could be implicitly leaning towards the father, due his colored physical characteristics resembling those from that bloodline, while the mom doesn't, but in the end nothing is confirmed.
- No Full Name Given: Their given names are never revealed, but their family names are known to be Tokito through their children's full names being stated.
- Together in Death: A variant. They reunite with their elder son Yuichiro after his death, and briefly reunite with Muichiro when he passes out from exhaustion after defeating Gyokko. Strangely enough, they are absent for Muichiro's death.
- Too Good for This Sinful Earth: Two genuinely kind and loving parents die from nature and circumstance.
- Unnamed Parent: Their names are never revealed, not even in extra materials despite the father's little but important role in Muichiro's life and later memories awakening.
- You Remind Me of X: The father is Tanjiro (or Tanjuro) in all but name, his personality is completely like theirs, that's why every time the emotionally stunted Muichiro was taken aback by something Tanjiro said was actually him subconsciously remembering his father. He even has the same eyes of them.
Yuichiro Tokito
Voiced by: Kengo Kawanishi (Japanese), Griffin Burns (English)Other VA
- An Arm and a Leg: He lost his left arm from a demon, trying to protect Muichiro and dies as a result, due to losing too much blood.
- Big Brother Instinct: When a demon came to their home and tries to attack Muichiro, Yuichiro immediately jumps in the demon's way to protect his brother, losing his left arm as a result.
- Cruel to Be Kind: Yuichiro was deliberately mean to Muichiro because he believed Muichiro's kindness would eventually spell out his death just like their father's kindness caused both him and their mother to die, leaving them both alone. Even in death, Yuichiro tries to sternly tell off his younger brother for choosing to die fighting instead of running away to live another day. He is forced to admit that he didn't want Muichiro to die after the Mist Pillar sternly rebutted that he is satisfied that his death had meaning.
- The Cynic: While Muichiro took after his father, being kind and emotive towards others, Yuichiro became cold and strict, believing that doing good things for others wouldn't do a person a shred of good. Because of this, he had an impassive look on life.
- Early-Bird Cameo: He is seen playfully splashing his brother with river water while his parents happily look on in the ending credits of Season 3. However he is out of frame with only his hand visible.
- Foil: To his ancestor Michikatsu Tsugikuni aka Kokushibo. Both were older twin siblings that had younger siblings whom were ultimately were destined for far greater than they would ever be. However, Yuichiro acknowledged the qualities he lacked that Muichiro had were what made his brother a special person and accepting he would never be special himself. Meanwhile, even in the end, Kokushibo is unable to fully understand where he went wrong in his life was becoming resentful toward his special brother, allowing his insecurities to blind him to what was truly important and throwing them away. To fully illustrate their differences, Kokushibo was dragged into Hell without anyone to accompany him, while Yuichiro reunites with his twin brother in the afterlife, while being sad at the realization that his younger twin being special doesn't mean that he's immune to any misfortune.
- Identical Twins: He was an identical twin brother of Muichiro.
- Identical Twin ID Tag: To distinguish him from his brother in terms of appearance, he wears a dark mist patterned yukata reflective of his personality, in contrast to Muichiro's light yukata.
- Informed Ability: The 2nd Databook states Yuichiro was just as gifted as Muichiro in potentially becoming a great demon slayer, but since he dies before any of that is realized the audience is only left to wonder; he carrying more wood logs than Muichiro is a glimpse of his innate strength, however. Yuichiro being equally gifted as Muichiro is only fully seen in the Gakuen / Academy universe.
- Jerk with a Heart of Gold: Yuichiro was highly hot-headed and rude towards others and was incredibly strict and harsh towards Muichiro, believing that his kindness is going to have him killed. Despite this, Yuichiro proves to have a good heart, as he does not hesitate on trying to protect his brother from a demon and as he lays dying, begs the gods to spare his younger brother, apologizing for his harshness towards him.
- Perpetual Frowner: Is usually seen with an irritable scowl.

- Posthumous Character: He died before the start of the series.
- Refusal of the Call: Amane Ubuyashiki appeared at the Tokito home to try and recruit the brothers due to their Heroic Lineage, but Yuichiro rejected her offer. She kept showing up repeatedly, but Yuichiro turned her down every time, eventually getting abrasive and then violent with his rejections.
- Small Role, Big Impact: Despite his limited time in the series, Yuichiro's death had a big impact on Muichiro, as he was deeply traumatized by the death of his brother that he shuts himself off emotionally and loses his memories of his family life as a result.
- Together in Death: With his parents after his death, and with his brother Muichiro after he perishes during the fight with their ancestor Kokushibo. He is deeply saddened that Muichiro had also died young.
- Took a Level in Cynic: After the death of his parents, Yuichiro became cold, strict, and harsh towards Muichiro, due to his belief that they need to be hard enough to survive.
- Used to Be a Sweet Kid: It's heavily implied that as a young child, he was just as cheerful as his brother before the death of his parents molded him into the cynic he is.
- Walking Spoiler: His mere existence is a plot twist.
- Would Hit a Girl: Downplayed. Fed up with Amane's persistent attempts to recruit the Tokito brothers, he throws water at her, causing a argument between the two brothers, and Amane taking the hint and leaving them alone, at least until a demon attacked the Tokito residence. It's unknown whether he would've thrown a more blunt object at her had he had his hands on it.
Iguro Family (Major Spoilers)
As a whole
- Abusive Parents: Obanai Iguro's mother, along with her other relatives, raised Obanai in a cage like a pet, pampering him up as a sacrifice for the Snake Demon to consume, which even includes mutilating his face to make it look more similar to the Snake Demon's.
- Asshole Victim: All except for Obanai's lone cousin were slaughtered by the Snake Demon for allowing Obanai to escape. However, given the fact that they all were a clan of thieves who made a living by sacrificing their own newborns to a demon and letting said demon kill their targets to steal their wealth, it's clear that they all deserved to be wiped out.
- Bandit Clan: They are an all-female clan of bandits that lives in splendor at expense of their victims that get slain by the Snake Demon they worship.
- Bastard Bastard: The lack of males, and Obanai never mentioning his father implies that the Iguro's children are born out of wedlock.
- Cruel Mercy: They provide Obanai with copious amounts of meals, but the smell of grease flooded his cage, and instead ended up making the boy refuse to eat out of nausea.
- Deal with the Devil: They all made a deal with the Snake Demon they revere: the Snake Demon receives the worship and newborns to eat, the Iguro family receives the money from the Snake Demon's victims.
- Death of a Child: As well as the newborns sacrificed to the Snake Demon, it's unfortunately heavily implied that the younger Iguro girls were also killed by the Snake Demon following Obanai's escape.
- The Faceless: Save from the cousin who survived the Snake Demon's massacre, the Iguro's aren't drawn with facial features, fittingly giving them a more ominous a dehumanizing appearance.
- Fattening the Victim: Implied; they always gave Obanai an overabundance of rich meals, but since Obanai was always meant to be a Human Sacrifice to be offered to the Snake Demon, it appears that they did that more to nourish him well so that the demon could have a more satiating feast.
- Hate Sink: As a collective, the entire family does not elicit any sympathy, given that they're a demon-worshipping clan that gleefully sacrifices their own young to an infant-eating demon in exchange for ill-gained riches. Thus, no tears are going to be shed over their deaths at the hands of a demon that they worshipped.
- Hoist by His Own Petard: The Snake Demon that the Iguro family have worshipped and fed babies to in exchange of riches ended up becoming the very same thing that led to the entire family's death, with the demon slaughtering them all in a fit of rage when Obanai escaped.
- Human Sacrifice: They sacrificed their own newborn for the sake of appeasing the Snake Demon in exchange for her providing them with wealth and riches.
- It's All About Me: As a whole, the entire clan sees value only in themselves and their luxurious lives, willing to sacrifice even their own newborns to the Snake Demon that provides them with riches from the people she kills.
- Karmic Death: A clan of bandits that relied on the Snake Demon to give them undeserved wealth was ultimately exterminated by the very same demon.
- Multigenerational Household: The whole Iguro’s clan are mostly women like grandmother, aunties, and cousins.
- Offing the Offspring: They offer their own newborn children as sacrifice for the Snake Demon to eat.
- Posthumous Character: With the sole exception of Obanai's sole surviving cousin, they all are dead by the present day, slaughtered by the Snake Demon in a fit of rage over Obanai's escape.
- You Have Failed Me: For allowing Obanai Iguro to escape, they all were slaughtered by the Snake Demon in a burst of rage. Only one member of their family survived: Obanai Iguro's sole remaining cousin.
Obanai's cousin
- Berserker Tears: She constantly cries in rage while yelling at Obanai Iguro, blaming him for her family's death.
- Blaming the Victim: She blames Obanai for the death of their family at the hands of the Snake Demon, simply because he didn't want to die as a sacrifice as she and the rest of her family wanted.
- Entitled Bitch: She hates Obanai for the fact that he chose to run away, rather than allow himself to be sacrificed to the Snake Demon, which resulted in her family being killed, uncaring to the fact that the Iguro family was a Bandit Clan that thrived on death and suffering of others.
- Even Evil Has Loved Ones: Pretty much the sole positive thing one could say about her is that she appears to genuinely care for the rest of the Iguro family, with her hatred for Obanai being fueled by his indirect role in their deaths.
- Family Eye Resemblance: She has the same almond-shaped eyes as Obanai. Although she lacks his heterochromia and instead has blue eyes.
- Karma Houdini: The second fanbook reveals that, after being saved by Shinjuro Rengoku, she took the leftovers of her family's accumulated wealth and lived a happy, wealthy life with husband and kids, still uncaring of the ill-gained nature of her luxuries and showing zero remorse over her verbal abuse of Obanai.
- Lack of Empathy: As far as she's concerned, Obanai is supposed to be just a sacrifice and should've accepted his impending death at the Snake Demon's hands without complaint. And when he chose to prioritize his life over death, which resulted in the Snake Demon slaughtering the entire Iguro family except for her, she chews him out, yelling that he should've stayed put and died as a sacrifice he was meant to be.
- Misplaced Retribution: Although it was the Snake Demon who slaughtered her family, she chooses to blame Obanai for their deaths, claiming that it was because of his escape that she massacred the clan and that she wouldn't have done that if Obanai stayed in his cage and allowed the demon to eat him as a sacrifice.
- Small Role, Big Impact: She appears only very briefly in a flashback, but her callous scathing remarks to Obanai that he should've died instead of her family is what fuels his Survivor Guilt and deeply-rooted self-loathing to this very day.
- Sole Survivor: In the aftermath of the Snake Demon's rampage in response to Obanai's escape, only one cousin of his survived. She was not happy about it.
- What Happened to the Mouse?: Her ultimate fate after her rescue by Shinjuro Rengoku has never been revealed in the manga. The second fanbook, however, reveals that she actually used the leftovers of the Iguro family's ill-gained wealth to live a happy life.
- You Should Have Died Instead: After her family was slaughtered by the Snake Demon because of Obanai's escape, she screams in rage, blaming him for her family's death, shouting that Obanai should've stayed in his cage and allowed the Snake Demon to eat her.

- Papa Wolf: He loves his daughter very much and did his best to keep her safe and healthy. He also looks after Hakuji almost like a father figure for the young boy, which makes his death even more tragic since Hakuji not just a mentor but another father figure.
- Passing the Torch: When Hakuji turned 18, he proved to Keizou that he was ready to become the Soryuu Style Dojo's next successor and Keizou even allowed him to marry his daughter, knowing that both of them had bonded and were very much in love with each other.
- Stepford Smiler: He's always shown to be happy and smiling, but deep down, he's still hurt over his wife's suicide and his daughter's ill condition. It was thanks to Hakuji that he managed to find peace within himself.
- Too Good for This Sinful Earth: He was a very humble and friendly man. Unfortunately, he had gotten poisoned by the rival dojo because they could not best him or Hakuji in sparring.
Koyuki
- Apologises a Lot: When she was sick, she always apologized to Hakuji for being a burden and having him taking care of her daily while missing out the chance of going outside like the other youths did. Hakuji didn't mind, but he certainly felt uncomfortable when she cried often.
- Because You Were Nice to Me: She fell in love with Hakuji because he didn't treat her as fragile or someone to pity. Instead, he treated her as a caring friend.
- Brooding Boy, Gentle Girl: She is the Gentle Girl to Hakuji's Brooding Boy.
- Delicate and Sickly: Koyuki was born with a weak body and remained ill for most of her life. It was the efforts and care of Hakuji that helped her recover and she was able to enjoy a normal life for the first time.
- Exotic Eye Designs: She has flower-shaped pupils.
- Luminescent Blush: She blushes innocently and happily when hearing that Hakuji would continue on her father's dojo and when he confesses his love and protection for her.
- Morality Chain: Losing her was the final step in Hakuji's transformation into the monstrous Akaza. He had no more will to live or care about anything without her. Quite fittingly, her spirit is also what breaks Muzan's control over Akaza at long last.
- Nice Girl: She's a very sweet and kindhearted young girl who became Hakuji's best friend and eventually, his lover.
- The Promise: When Hakuji was nursing Koyuki, he made a promise to her, saying that they would one day see the fireworks when she got better. And their promise finally came true when she finally recovered from her sickness. Hakuji soon made another promise to Koyuki, his Declaration of Protection for her and her father.
- Snow Means Love: Koyuki invokes this trope literally, as her name contains the charcters for both "love" and "snow". She had snowflakes as a design motif and her love for Hakuji is what gave him a true sense of purpose in life. This also tragically invokes Snow Means Death, as her death serves as Hakuji's Despair Event Horizon towards his transformation into Akaza.
- Tender Tears: When she was sick, she would always cry because of Hakuji's kindness towards her, which made him feel uncomfortable internally.
- Too Good for This Sinful Earth: She was a kind and innocent young girl who certainly did not deserve to get poisoned by the rival dojo.
- When She Smiles: Because she was ill at first, she was always in distress. After Hakuji helped her recover from her sickness, she was able to smile more often.
- You Are Worth Hell: She follows the repentant Hakuji into hell at the end.

Three people who make the mistake of bumping into Muzan and antagonizing him.
- Alas, Poor Villain: They were a trio of smarmy drunk con-artists, but Muzan's murdering of them was way over the line, especially with how terrified the woman was after the other two were killed. The former is most certainly NOT played even as Black Comedy.
- Alcohol-Induced Idiocy: You've got to be pretty drunk to pick a fight with The King of the Demons.
- Asshole Victim: Zigzagged; Given their revealed history with Zenitsu coupled with the fact they willingly picked a fight with Muzan does not make one feel too sorry for them, as disproportionally brutal as their fates ended up (especially for the lady).

Kotoha Hashibira
Voiced by: Mamiko Noto (Japanese), Jennie Kwan (English)Other VA
The mother of Inosuke Hashibira, who was killed when Inosuke was a baby.
- Born Unlucky: Her life absolutely sucked, being married into an abusive family, escaping to the Paradise cult with the infant Inosuke, and then finding out Doma was a demon eating his followers and was killed and eaten by him after being forced to drop her son off a cliff to spare him. But despite her sad life, she was happy because she had Inosuke.
- Deceased Parents Are the Best: She loves her son very much and she always sang him the pinkie promise songs when he was a child. After she discovered Doma's true colors, she decides to drop him off a cliff so he won't share the same fate as her before being killed by Douma.

- Domestic Abuse: The reason she joined the Eternal Paradise cult? Her husband was incredibly abusive and regularly beat her.
- Heroic Self-Deprecation: She considers herself stupid for first marrying an abusive man who beat her nearly blind in one eye, then for following the demon Doma which put herself and her son in mortal danger. However, she redeemed her ignorance by saving her son's life in a last-ditch effort.
- Kindhearted Simpleton: Doma described her as a very kind but unintelligent woman. Given how he viewed his other followers, it is unknown if she truly was as dimwitted as he thought her to be.
- Mama Bear: Her first priority was always Inosuke, though her first instinct was to escape with him rather than fight. She ran away from her husband because he was getting violent over Inosuke's crying.
- Morality Pet: Perhaps too strong a term, but Doma seemed as fond of her as he could possibly be of a human being. By his own admission, he enjoyed her purity and had no plans to ever kill her. It was only when she discovered his nature and fled that he acted to kill her. For someone like Doma, this is an unbelievable level of benevolence.
- Nice Girl: Kotoha was a gentle young mother who loved her son Inosuke very much. She even showed respect for Douma for saving her and her son and always sang for him, up until she found out his true colors.
- Posthumous Character: She died when Inosuke was just a baby, having been killed by Doma after she tried to escape his cult.

- Teen Pregnancy: Doma says she looked no older than 18 when he met her and baby Inosuke.

Rui's Parents
Rui's mother voiced by: Natsuko Kuwatani (Japanese), Bridget Hoffman (English)Other VA
Rui's father voiced by: Shinnosuke Tachibana (Japanese), Kyle Hebert (English)Other VA
Top, Rui's father; bottom, Rui's mother.
The biological parents of Rui, who loved and cared for him very much. However, when he became a demon and started eating people to survive, they felt they had no choice but to kill him and then themselves. He ended up killing them instead.
- Anime Hair: Rui inherited his father's hairstyle.
- Deceased Parents Are the Best: During Rui's flashback, his parents are shown to deeply care for him when he was human. Even when they decide to kill him, it is a last resort to keep him from killing others and they promise to kill themselves once they commit the deed. When Rui dies, he believes he will go to hell, but he is reunited with the spirits of his parents, who say that they will always stay together, even if they are in hell.
- Didn't Think This Through: Their plan was to kill Rui at night when he was sleeping and then commit suicide so they would all be together. Even setting aside the fact that stabbing him wouldn't have accomplished anything due to his new demon physiology, it never occurred to Rui's parents that if Rui sees them standing over him with the knife, he will assume the worst and kill them, which is exactly what happened.
- Driven to Suicide: It is revealed that Rui's parents were planning to commit suicide together after killing him as atonement for his crimes.
- The Faceless: Their faces are not shown in flashback, as Rui cannot remember clearly what they look like. Until he dies and is reunited with them.
- Family Eye Resemblance: As a human, Rui inherited his mother's eye color, shown in concept art.
- Killed Offscreen: Both were killed offscreen by Rui after failing to kill him themselves.
- Murder-Suicide: Rui's parents intended to kill him after he became a demon to stop him from taking more lives, then kill themselves so they can all be Together in Death. Unfortunately, Rui ends up killing them when he sees them with the knife, leading him to conclude that they never cared for him and causing him to take a turn for the worst.
- My God, What Have I Done?: Their reaction when Rui commits murder after having become a demon.
- Offing the Offspring: A rare sympathetic example; after their child Rui became a demon and started eating people, they tried to kill him to keep him from taking any more innocent lives. And it's very clear they were not happy about this at all, as they were going to kill themselves once they commit the deed.
- Once More, with Clarity: After becoming a demon, all Rui can remember about his parents is the night they tried to kill him. However, after hearing his mother's last words, it causes Rui to remember his father's words that clarified that they were planning to kill themselves afterward so he wouldn't be alone in the afterlife, and that his mother's last words were an apology for not being able to give him a stronger body.
- Parents as People: What they were in the end. Killing your own child is a terrible thing to do, but it's more understandable when the child has become a human-eating monster who's killed someone and will likely kill again, as Rui had. Rui's parents were willing to kill themselves as part of their atonement for their son's crimes, and even joined him in Hell. In the end, Rui admitted that his anger toward his parents prevented him from understanding them, or acknowledging that their bond with him was genuine.
- Posthumous Character: Rui killed them both before the beginning of the story.
- Small Role, Big Impact: Losing them caused Rui to desire a family of his own that would never betray or harm him. He convinced other demons to join his "family," and became a Control Freak so they would always do what he wanted and perform the roles expected of them.
- True Blue Femininity: Rui's mother wore a blue kimono, patterned with light blue flowers.
- Unwitting Instigator of Doom: Rui thought his parents didn't love him after they tried to kill him. He would go on to create a Family of Choice consisting of other demons while keeping them in line with Domestic Abuse.
- You Are Worth Hell: When Rui dies, his parents appear and promise him that they will never leave him again, even if the three of them are condemned to hell forever.
Enmu's Pawns
Train Conductor voiced by: Jun Kasama (Japanese), Kirk Thornton (English)Other VA
Girl who entered Rengoku's dream voiced by: Sayaka Senbongi (Japanese), Mela Lee (English)Other VA
Boy who entered Tanjiro's dream voiced by: Takuya Eguchi (Japanese), Matthew Mercer (English)Other VA
Girl who entered Inosuke's dream voiced by: Hibiku Yamamura (Japanese), Michelle Ruff (English)Other VA
Boy who entered Zenitsu's dream voiced by: Yūya Hirose (Japanese), Erik Kimerer (English)Other VA
Train Engineer voiced by: Shinya Takahashi (Japanese), Crispin Freeman (English)Other VA
Top to bottom: Train Conductor, Entered Rengoku's subconscious, Entered Tanjiro's subconscious, Entered Inosuke's subconscious, Entered Zenitsu's subconscious, Train Engineer.
Civilians recruited by Enmu to serve his purposes in exchange for Enmu giving them pleasant dreams. One train conductor, one engineer, and four teenagers (two boys and two girls).
- Advertised Extra: Minus the engineer, they are featured in the Mugen Train Arc's intro, despite playing rather minor roles, not even having names, and disappearing less than halfway through the story.
- Alas, Poor Villain: They're all willing to sacrifice the passengers on the Mugen Train for their own benefit, but it becomes clear that Enmu simply took advantage broken people down on their luck who are desperate enough to do anything to escape from their situations.
- Ambiguous Situation: It's unknown what the teens attempting to destroy Rengoku, Inosuke, and Zenitsu's spiritual core's, or the engineer's backstories are. They are presumably either grieving, like the train conductor, or sick, like the boy sent inside Tanjiro's dream.
- Because You Were Nice to Me: Touched by the boy's kind and pure spiritual realm, the boy who entered Tanjiro's dream can't bring himself to destroy it. Later on when they both wake up, he wishes Tanjiro luck in his venture.
- Curb-Stomp Battle: Against a trained demon slayer, the teenagers who try to attack Tanjiro (minus the recruit who entered his subconscious, who stayed out of it) stood no chance and are swiftly knocked out.
- Exhausted Eye Bags: All have this.
- Eyes Always Shut: The girl who entered Inosuke's dream is always squinting.
- Girlish Pigtails: The two teenaged girls have them.
- Karma: The engineer that stabs Tanjiro gets severely injured from the train crash following Enmu's death, although he survives. Although, Inosuke wants to let him rot, Tanjiro claims that he's had enough punishment.
- The Lost Lenore: The train conductor is motivated to obey Enmu's orders due to desperately wanting to be reunited with his dead wife in daughter via Enmu's dream powers.
- No Name Given: As should be obvious, none of Enmu's recruits are named.
- Not Brainwashed: When 3 out of the 4 teenagers woke up, with one trying to attack Tanjiro, he at first assumed that Enmu had possessed them, although when one of them revealed that the boy who entered his mind had tuberculosis, he quickly deduced that Enmu has instead preyed upon the desperate.
- No Sympathy: Inosuke has no patience for the engineer that stabbed Tanjiro, even imploring Tanjiro to leave him for dead, although the ever kind boy refuses to have his death on his hands.
- Small Role, Big Impact: All the train conductor did was punch the passenger's tickets, but doing so activated Enmu's blood demon art, as his blood was mixed in with the ink, starting the plot of the Mugen Train arc.
- What Happened to the Mouse?: The train conductor disappears from the story after Enmu puts him to sleep, the 4 teenagers after Tanjiro confronts Enmu, and the train engineer after Enmu's death and Akaza's arrival. Given that it's expressly stated the the Mugen Train suffered 0 casualties, it very likely all survived. None return or are mentioned in future arcs. Although the teenagers do reappear in Kimetsu Gauken installments featuring Enmu.
- Would Hurt a Child: The 4 teenagers Enmu recruits are specifically sent to destroy the spiritual cores of not only Rengoku, but also the teenaged Tanjiro, Inosuke, and Zenitsu, which would kill them. When that fails they attempt to stab Tanjiro, which also fails. Only the train engineer manages to land a stab on Tanjiro while his guard was down.
Koinatsu
Voiced By: Chiwa Saitō (Japanese), Vivian Lu (English)Other VA
- Beauty Equals Goodness: She is considered one of the most beautiful courtesans in the district, rising to the status of oiran, and is also one of the kindest characters in the series. This contrasts with Daki, who is in a similar position but embodies Beauty Is Bad.
- Benevolent Boss: She treats the girls working under her very well, and they view her as a big sister figure in return.
- Good Counterpart: She serves as one to 'Warabihime', aka Daki. Both are oiran renowned for their beauty, but Koinatsu treats all around her with kindness and respect while Daki is cruel and petty to those who work with her. Daki also puts on a very fake and transparent Yamato Nadeshiko act when in public, but in private or when in her true demon form she is as far from ladylike as possible, while Koinatsu is very genuine in her behavior both in public and in private, embodying the traditional qualities of the trope.
- High-Class Call Girl: She works as an oiran, a type of Japanese courtesan.
- Hooker with a Heart of Gold: She is a courtesan and incredibly kind to everyone around her, particularly her assistants. She also treats Tanjiro very well despite immediately seeing through his disguise.
- Onee-sama: She has a sisterly relationship with the girls who work as her assistants, treating them kindly and rewarding them with candy often. They are saddened when she informs them of her engagement and departure.
- Retirony: Koinatsu becomes engaged to a client and plans to retire from her work as a courtesan, but she gets kidnapped by Daki the night before she was to depart.
- Unknown Rival: To Daki, who views her as a rival for the status as most beautiful oiran in the district. Koinatsu is unaware of Daki's resentment towards her and is very shocked when she is attacked and kidnapped.
- What Happened to the Mouse?: She is never seen or mentioned again after getting rescued by Tanjiro, until an omake reveals that she's one of Tanjiro's many penpals.
Omitsu
Voiced by: Kaoru Katakai (Japanese), Cassie Ewulu (English)Other VA
Omitsu was the manager of the Kyogoku House in the Entertainment District of Yoshiwara, Tokyo.
- Didn't Think This Through: She decided to confront Warabihime about her behaviour, bringing along a hidden knife for self-defence after figuring out that Warabihime's not human. However, Omitsu failed to take into account that Warabihime/Daki's cruelty would make her more than willing to capture and murder her almost immediately, following a spot of Evil Gloating.
- Everyone Has Standards: Omitsu did turn a blind eye to Warabihime's abusive behavior toward the other girls in Kyogoku House in order to keep their business working, since she's their top earner. However, Warabihime bullying another girl to the point of running away and possibly committing suicide is far too much for her to tolerate.
- Explain, Explain... Oh, Crap!: While confronting Warabihime about her behavior, Omitsu recounted an old tale about an Oiran known for her seemingly ageless appearance and incredible beauty — as well as her extreme cruelty to others. Omitsu slowly notices the parallels between the Oiran's behaviour and Warabihime's, causing her to realise that the two of them are the same person and that Warabihime isn't human at all. Unfortunately for her, this realisation crystallises moments before Warabihime/Daki captures her.
- He Knows Too Much: Omitsu figured out that Warabihime is a demon, causing Daki to drop her off the House's roof to preserve her cover identity.
- High-Altitude Interrogation: On the receiving end of one from Daki, who shifts into her demonic form and drags her into the air above the House to taunt Omitsu before killing her.
- Make It Look Like an Accident: Daki had made look that Omitsu's death to seem she falling out from window. It's had rumored around the entertainment direct to believe or tells the events about Omitsu's death.
- Tears of Fear: After Daki captures her, she's left crying from terror as she realises Daki's going to kill her.
- Too Dumb to Live: Omitsu confronted Daki, who she knows isn't human, with nothing but a kitchen knife and that knowledge. Daki even lampshades how stupid Omitsu was to do this and how she could have lived longer had she tried to expose Daki any other way.
- Silk Hiding Steel: Omitsu confronts Daki/Warabihime about her behaviour after it caused at least one other worker commit suicide, despite Warabihime's fearsome reputation in the house. Unfortunately Omitsu isn't the first person to have confronted Daki before, and she meets the same fate as them.
- Small Role, Big Impact: While she only appears for a couple chapters, her death played a critical role in the search for clues on Daki's identity as demon, as it helped the Sound pillar to get information from the House's master.
Daki's Mother (spoilers)
Daki's Mother
Voiced by: None
Ume's/Daki's and Gyutaro's long-deceased mother, a prostitute who lived and worked in the lowest class of the Entertainment District.
- Abusive Parents: Calling her a parent at all would probably be too generous. She hated Gyutaro for being born a boy because it was bad for her line of work, beat him regularly as a way of venting her frustrations, and fed him so little that he had to eat mice and insects to survive. She did not treat Ume any better, once trying to cut her hair off when she was a baby.
- Bait-and-Switch: Throughout the Entertainment District arc, Gyutaro has multiple short flashbacks of her dead body in a way that implies she died tragically. It turns out she was the cause of his and his sister's misery.
- The Chain of Harm: She led a miserable and poverty-ridden life, having to prostitute herself just to survive in the most impoverished area of the Entertainment District, and took out her rage and bitterness on both of her children.
- Dishonored Dead: It is visually implied that she was not given a proper funeral after dying, as Gyutaro's flashbacks show her rotting body in the family's shack, surrounded by flies. Given her treatment of him when she was alive, it's likely that even if he could have afforded a funeral, he wouldn't have given her one anyway.
- The Faceless: Her face is never clearly shown, as she always has her eyes shadowed or her back turned to the camera.
- Green-Eyed Monster: She was deeply envious of beautiful women. When Ume was only a baby, her mother was jealous of her beautiful white hair and tried to cut it off. This was the last straw for Gyutaro, who finally found the courage to stand up to her.
- Hate Sink: Any pity the viewer might feel for her due to her miserable life flies out the window when it is revealed how badly she abused Gyutaro for being an unwanted child and a boy besides—beating him, starving him, trying to kill him and worse. Not only that, but her jealousy of beautiful women was so irrational that she tried to cut Ume's hair off when she was a baby.
- No Name Given: Her name is never mentioned.
- Offing the Offspring: She tried several times to kill her son Gyutaro before and after he was born, but never went all the way through with it, for unknown reasons.
- Posthumous Character: In the present, she has been dead for more than a hundred years and only appears in Gyutaro's flashbacks.
- Single Mom Stripper: She was a dirt-poor prostitute with two children, neither of whom she wanted or loved. It is all but said that Ume/Daki and Gyutaro were illegitimate children fathered by her clients.
- Small Role, Big Impact: If she had loved her children even a tiny bit, maybe Gyutaro and Daki would not have grown up to hate the world so much and take their rage out on it as powerful demons.
- Struggling Single Mother: She was so poor that she could barely afford to take care of herself and her children—not that she tried very hard.
- The Voiceless: She only appears in a flashback and does not have any speaking lines.
- Walking Spoiler: By proxy, talking about her necessitates revealing the existence of her son Gyutaro, the other Upper Rank Six who is not revealed until late into the Entertainment District Arc.
- Wanted a Son Instead: Inverted—she hated Gyutaro for being born a boy, seeing him as a financial liability because she couldn't pimp him out when he came of age, due to his gender. Not that she treated her daughter better anyway.
- Who Names Their Kid "Dude"?: She named her daughter "Ume," meaning "syphilis," after the disease she herself was dying from. Gyutaro remarks how terrible a name it was, although he thinks that "Daki," the name his sister chose to replace it after becoming a demon, is not much better.
- Would Hurt a Child: Gyutaro notes that she tried to kill him after he was born, and in the anime we see her pinning a young Gyutaro down and slowly beating his back.
Mitsuri's Parents
Father voiced by: Kenji Nojima (Japanese), Ricco Fajardo (English)
Mother voiced by: Junko Minagawa (Japanese), Jennifer Sun Bell (English)
Dad Kanroji on the right; Mom Kanroji on the left.
Mitsuri's completely normal parents, the average small city couple in early 20th century Japan who happened to birth the extraordinary Mitsuri and later four common younger siblings. Mitsuri being unique didn't make her parents love her any less, growing worried when Mitsuri felt she didn't belong among common folk as she grew older.- Adaptation Expansion: Their appearance in the anime was extremely expanded, as much as it could for such minor characters; in the manga we only get two panels showing what they look like, they didn't speak a single line.
- All There in the Manual: Mitsuri comments offhandedly that she has younger siblings, her full family is never properly clarified in the manga and anime, the latter does show her first younger brother but it is only the 2nd Databook that specifies the full family, Mitsuri has four younger siblings, as such her parents had five children.
- Eyes Always Shut: The anime took the only manga panel seen with Mitsuri's father, where he smiles with his eyes shut by his wife's side, and just went with it being his normal state in the anime.
- Good Parents: Two of the best parents shown in the series, and that's saying a lot since there are quite a lot of them most are either Abusive Parents, Posthumous Characters, or both. They loved and supported Mitsuri unconditionally, teaching her to be proud of her incredible strength and appetite despite others finding them freakish. In fact, the narration even notes they were greatly concerned when Mitsuri began to dye her hair and force herself to eat little after getting brutally rejected by a suitor for her unique traits. They also hold the unique status as the only known complete living family over the course of the story; barring Mitsuri from suffering the same tragedy many other characters have gone through.
- No Full Name Given: Their given names are never revealed, but their family names are known to be Kanroji through their daughter's full name being stated.
- Not So Stoic: Mitsuri's mother was known for being calm and collected, but seeing a toddler Mitsuri lift a large rock caused her to go into shock for the first time. She later pets her daughters head with an amused yet bewildered smile.
- Outliving One's Offspring: The happy fact that they are the only known complete living family throughout the series takes a sad turn after the final battle, Mitsuri is one of the several fallen against Muzan, the manga spares the readers from seeing her parents' reaction to the news on Mitsuri's death but knowing how much they loved their daughter, it must have pained them a lot.
- Unnamed Parent: No names for them, not even in the Databooks; it sticks out since they are actually alive throughout current events in the story, unlike many other parents in the series.
The Magistrate (Unmarked Spoilers)
Voiced by: Daisuke Egawa (Japanese), Joe J. Thomas (English)Other VA
A magistrate who sentenced Hantengu to execution for his crimes, only to be killed by Hantengu after the latter was turned into a demon by Muzan.
- Defiant to the End: Combined with Did You Just Flip Off Cthulhu?. While people are usually afraid of demons, the Magistrate neither pleads for his life nor takes back his words about Hantengu, instead proudly standing his ground by continuing to call out Hantengu for his crimes. He knows that he won't survive Hantengu's attack on him, but he still goes out of his way to call out Hantengu's delusional belief about his innocence and tells him that he will one day pay for his sins with his life.
- No Name Given: His name is never revealed even once during Hantengu's flashback of his last moments as a human and just before he killed the Magistrate.
- No Sympathy: He rightfully calls out Hantengu for his misdeed and calls B.S. on all excuses he brings in his defence, and outright tells Hantengu he's got zero sympathy for any of the latter's attempts to emotionally manipulate others to avoid being punished.
- Pay Evil unto Evil: When Hantengu tries to claim that his hands did all of his crimes and not him, the Magistrate decides that Hantengu will have his hands cut off before he dies.
- Posthumous Character: He's long dead by the time the story begins, but his last words of defiance towards Hantengu are still engraved in his subconscious.
- Royals Who Actually Do Something: Well magistrates who actually do something. He's pretty competent at his job, and instantly deduces that Hantengu is faking his disability simply because he knew which direction to face while speaking to him.
- Spotting the Thread: When Hantengu tries to plead that he's just a blind, innocent old man, the Magistrate sees right through his lies because a blind anma masseur who normally visits him would always face a wall before the magistrate starts talking, yet the fact that Hantengu was facing him the entire time proves that he can see.
Tsutako Tomioka
Tsutako was the older sister of Giyu Tomika.
- All There in the Manual: the databook explore Giyu's backstories from after match of Tsutako's sacrifice. It's revealed once Giyu try told the people about event, however the townspeople believes that Giyu was suffering emotional disorder and was going to be send to mental hospital by Giyu's relative. However, while he was being taken there, he escaped and ran to a mountain. When he was barely at death's door, he was found and saved by a hunter who was friends with Urokodaki.
- Big Sister Instinct: She was going to be wed by the next day until the demon came to attack the siblings. So she decided to risk her life to protect her little brother Giyu from the demon's attack, giving the chance for Giyu to live.
- Elemental Eye Colors: She has the same blue eye color of her little brother Giyu.
- Heroic Sacrifice: She sacrificed herself in order to protect her little brother Giyu from a demon.
- The Lost Lenore: Her death caused Giyu to have survivor's guilt and problems interacting with others.

- Posthumous Character: She was killed long before the story starts.
- Promotion to Parent: She raised her little brother Giyu with the remaining money their parents had left after dying from a disease.
- Small Role, Big Impact: Because of her sacrifice, Giyu became a demon slayer and later spared Nezuko's life and sent Tanjiro to Urokodaki.
Gyomei's Orphanage
A group of 9 orphans lived with a young Gyomei Himejima in a temple when he used to be a priest. All but two would be killed by a demon after one of the kids betrayed the others to spare his own life.
- Death of a Child: Mercilessly slaughtered by a demon, with Gyomei describing 4 as dying immediately, and 3 having their throats slit.
- Extremely Protective Child: It turns out they chased out Kaigaku after he was caught stealing from them and ran off to protect Gyomei from the demon attacking them.
- Orphanage of Love: They had no families other than each other and lived together in harmony.
- Posthumous Character: They were killed about 10 years before the story starts.
- Small Role, Big Impact: Their deaths and assumed betrayal of Gyomei caused him to have a sever mistrust of children, and inadvertently got him to change careers to demon slayers.
- Together in Death: Reunite and make amends with Gyomei after his death.
- Underestimating Badassery: Believing that Gyomei's blindness meant he was helpless, 3 children ignored his pleas to stay with him and attempted to fend off the demon themselves. They had no idea that with just enough rage and determination, Gyomei could kill the demon all by himself.
- Undying Loyalty: They never selfishly ignored Gyomei like he thought and instead tried to protect him from an invading demon.
- Ungrateful Bastard: Definitely counts for the kid who betrayed his found family to save his own skin. Given that it's later revealed that this was Dirty Coward and Jerkass Kaigaku, this makes a whole lot of sense. Gyomei also assumes this of the 3 kids who refused to listen to his pleas to stay close and ran off, believing that there reasoning was that a blind man couldn't protect them. It turned out that they only ran off because they wanted to protect him as they believed he couldn't fend for himself.
Sayo
- All There in the Manual: According to Gotouge, when Sayo began to cry about the monster man who killed everyone, he referred to the demon who attacked them, not Gyomei as he and others assumed. A now 14 year old Sayo severely regrets what happened and desperately wants to apologize to Gyomei. Unfortunately, she never got the chance as Gyomei would die from his injuries from fighting Muzan before she could.
- Baby Of The Bunch: She was the youngest orphan, being only 4 when the demon attacked them.
- Poor Communication Kills: After Gyomei defeated and killed the attacking demon, Sayo, who was severely traumatized, could only say "That man is a monster, he killed everyone." While she was referring to the demon, her lack of specification, plus the demon's body disintegrating caused Gyomei to be arrested and charged for murder. Had it not been for Kagaya, he would've been executed.
- Sole Survivor: Minus Kaigaku, she was the only child to survive the demon's raid on their temple.
Tsugikuni Parents (Unmarked Spoilers)
Akeno Tsugikuni
Mr. Tsugikuni
Akeno Tsugikuni and her unnamed husband, were the mother and father of Michikatsu and Yoriichi Tsugikuni. In particular, Akeno was also the creator of the hanafuda earrings that Tanjiro Kamado currently wears.
- Abusive Parents: Mr. Tsugikuni ordered Yorichii to be put to death at birth due to being disgusted by his birthmark and also thinking it was an omen. He also forbade the brothers from being with each other, and struck Michikatsu's face when he tried to talk to Yorichii. The only time we've seen him interact with Yoriichi was in the extra materials, when he told him his two year old son that he should have never been born, was ominous, and would bring disaster to their family. Yeah, he's not winning Dad of the Year Award.
- All There in the Manual: The extra materials reveal more on Tsugikuni household. It's reveal after Yoriichi had left the household, her husband began searching for him due to her last request.
- Aw, Look! They Really Do Love Each Other: It's revealed in the extra material that Akeno and her husband were often fighting each other, however he really did love her. This had a huge impact when he found out his wife was secretly dying. He cried embracing his wife's corpse over since she didn't tell him about her condition. Her husband never re-married after Akeno's death.
- Beware the Quiet Ones: People who knew Akeno were shocked after when she lashed out her husband for trying her son Yoriichi, as they were very unused to see someone with a quiet demeanor become so angry when confronting him.
- Delicate and Sickly: Unbeknownst to many, Akeno was slowly dying from a disease. The only who knew about it was Yoriichi, who often helped and assisted his mother while she was sick by walking close to her and supporting her left side. Unfortunately, it was revealed in the in extra material that because Yoriichi had been given bad treatment than his brother, that was the major source for Akeno's stress and the reason her disease got worse.
- The Faceless: Zig-zagged with Akeno. Her face wasn't shown in her first appearance during Michikatsu's flashback. To be fair, Michikatsu admits he couldn't remember his own mother's face or his father and even his own wife and children after living many centuries as a demon. Except Yoriichi. However, during Yoriichi's flashback Akeno's face is finally shown due to his own POV. It's played straight with their father however.
- Given Name Reveal: Her name is revealed in the extra material of volume 20.
- Hidden Depths: Akeno had share similar traits with Yoriichi for hating conflicts. In the extra materials, after giving Yoriichi the charm earrings in hopes to cure Yoriichi's deafness, that's where Yoriichi said his first words to show that he isn't deaf. When she ask why he didn't say anything before she realized it was so he could protect his father.
- Last Request: In her will, Akeno begged her husband to not only take care of their children and raise them in a healthy environment, but also to not separate them and treat them any differently.
- The Lost Lenore: Akeno's death massively impacted the Tsugikuni household. Her husband tried to fulfill Akeno's last request to raise both Michikatsu and Yoriichi. However, Yoriichi had already left the house the day his mother had passed away. It affect on Akeno's husband to have collapse in health both on Akeno's death and Yoriichi's sudden vanishment. Akeno was sorely missed by her husband and he never remarried again after her death.
- Mama Bear: When Akeno found out that her husband was considering to kill Yoriichi for his strange birthmark and being a twin (considered a bad omen during the Sengoku period), She became furious and angrily grabbed his kimono, needing to be restrained by two servants. And this was mere moments after she gave birth. Akeno loved both her children and was shown arguing her husband for their unequal treatment and when he hit Michikatsu for trying to spend time with Yoriichi.
- Morality Pet: For all her husband's flaws and how he treats their children, the only redeeming factor was his love for Akeno, being absolutely devastated by her passing. Yoriichi survived being killed by him because of her and why his father wanted to search for him was to acknowledge his wife's final will to let the twins be given equal treatment and raised together. After her death, he never remarried and died in his thirties in relief after Michikatsu married.
- Nice Girl: Akeno was a loving mother who cared and loved her twins equally.
- No Name Given: Mr. Tsugikuni is never given a name, despite his wife's being revealed.
- Not So Stoic: Akeno was known by people to be quiet and gentle, so it truly surprised people when she burst into anger when her husband wanted to kill a baby Yoriichi.
- Only Known by Their Nickname: Akeno was given the nickname "doll" due to her quiet and gentle personality.
- Prayer Pose: Yoriichi recalled that Akeno was a religious person when it's shown in a flashback that she is seen praying to god for bring luck and good fortune every morning. The Sun deity that she prays to everyday is more than likely the Shintō deity Amaterasu Ōmikami, since during the Sengoku period, multiple clans prayed to the kami for good fortune during warfare.
- Secretly Dying: Neither Michikatsu and her husband knew that Akeno was slowly dying except for Yoriichi, until Michikatsu learned the truth after Yoriichi told the news that their mother had passed away and after reading her diary that he found out she had been suffering on her left side for while.
- Small Role, Big Impact: All is by Akeno.
- Akeno was the reason why Yoriichi wasn't killed by his father, not knowing that Yoriichi would later become the creator of the first Breathing style and an incredibly powerful demon slayer who almost killed Muzan himself.
- She's the one who gave Yoriichi his hanafuda earrings, which would eventually be passed down to Tanjiro and serve as such a huge trigger to Muzan's PTSD that he would continuously send out demons to attack him.
- In a more unforunate role, her will led to Michikatsu developing a complexity of jealousy and hate to Yoriichi making him realize his brother was talented since birth leading him to accept Muzan's request to become a demon and becoming the Upper Moon 1, the most powerful demon seconded by Muzan.
- Take Care of the Kids: Akeno's last request for her husband is for him to try to take care of both of their children after she passes away which he acknowledged.
- Unwitting Instigator of Doom: Michikatsu reading his mother's final will made him crazy jealous/hate of his brother, realizing he was never weak and instead talented.
- Walking Spoiler: Both are Satellite Characters to the Tsugikuni twins so you really can't talk much about them without revealing their role in Yorichii and Michikatsu/Kokushibo's backstory. In addition, they are introduced in the latter's flashback and he's already a Walking Spoiler himself
Uta
A young girl that a young Yoriichi met during his travels. She befriends Yoriichi and soon, both of them get married when they become adults.
- Childhood Friend Romance: She became friends with Yoriichi when they were kids and after 10 years, they got married and Uta became pregnant with their child.
- Happily Married: She's married to Yoriichi and they loved each other immensely. He considers his time with her the happiest part of his life.
- The Lost Lenore: To Yoriichi. Her death at a demon's hands is what drove him to join the corps, leading to the chain of events that culminates in Muzan's eventual defeat. She was the love of his life and he is never interested in anyone else after her death.
- Meaningful Name: "Uta" translates to "song" in Japanese.
- Motor Mouth: Yoriichi mentioned to Sumiyoshi (actually Tanjiro viewing his memory) that this was a habit of Uta, where she could talk from morning to evening.
- Nice Girl: She is kind and loving individual.
- Sole Survivor: When Yoriichi first meets her in the fields, she tells him she was trying to catch tadpoles out of loneliness because all her family except her died from a plague.
- Supernaturally Marked Grave: The 2nd Databook, page 130, reveals the Blue Spider Lily, the one thing Muzan wanted in the whole world, coincidentally started growing in her grave, the late wife of Muzan's mortal enemy Yoriichi.
- Tears of Joy: Her tears fall from her eyes when Yoriichi asks her to accompany her home after seeing how lonely she was.
- Too Good for This Sinful Earth: Uta was a very kind girl who made Yoriichi incredibly happy, so of course she had to die tragically at a young age while carrying their child.
- What Beautiful Eyes!: Yoriichi commented that her eyes were like obsidian when they first met.
The Doctor (Major Spoilers)
Voiced by: Shomaru Zoza (Japanese), Kyle Hebert (English)
A generous doctor from the Heian Period, where Muzan was born in. He was assigned to cure the disease that resided in Muzan, but got offed by him out of anger and impatience. However, the medicine The Doctor gave to Muzan really did cure his disease after all, only to leave Muzan unable to walk in sunlight and thus beginning his start of darkness. The Doctor is a key character as he is technically the one who started the demon lineage through Muzan and his medicine.
- Adaptation Distillation: The manga originally portrayed him with a serene and kind expression, where the narrator specifically states he was a generous doctor just trying to care for Muzan; the anime portrays him with a somewhat suspicious expression and stoic mannerisms, where it is Muzan that narrates the doctor's existence, having no kind words to address him.
- Elixir of Life: Essentially, his experimental medicine granted Muzan semi-immortality as he is able to live for centuries, but the downside was that it made Muzan weak to sunlight.
- No Name Given: He wasn't named in Muzan's flashback, only referred to as just "The Doctor".
- Perpetual Smiler: The only expressions that we see from The Doctor are genuine smiles.
- Slippery MacGuffin: The Doctor had written in his notes about a medicine called the "Blue Spider Lily", which was the cure to solving Muzan's sunlight weakness and involved the use of a rare variant of the Spider Lily flower. Muzan searched near and far for the Blue Spider Lily to make the medicine for himself, but he didn't succeed in finding it. Instead, he chose the alternative to find and absorb a demon with sunlight immunity.
- Small Role, Big Impact: The Doctor only appears for a few panels, but the entire story would not have happened if it weren't for his attempt to help Muzan.
- Unwitting Instigator of Doom: The Doctor only wanted to cure Muzan's disease, but unintentionally made him into a powerful monster instead, setting up all of the story's events.
- We Hardly Knew Ye: All we knew was that he tended to Muzan and his experimental drug turned Muzan into a demon, but it was after The Doctor was offed by Muzan that Muzan realized that his drug really worked and we never hear anything else about The Doctor again.
Epilogue Characters (Major Spoilers)

- Last Episode, New Character: All are introduced in the very last chapter of the manga, which takes place in modern day Tokyo.
- Reincarnation: Yoshiteru wonders about this for all the lives lost fighting Muzan, pondering if they've been reborn to live happier lives. Considering the above, he might be onto something.
- Reincarnation-Identifying Trait: Although many are obvious reincarnations like Sumihiko or Touko looking exactly like their previous incarnations, there are one or two that are much less obvious, such as the reincarnation for the Tokito twins; they only have one panel for them as babies, and you can only tell who they are being the design of their blanket having the same mist pattern associated with them.
Kanata Kamado
- Dude Looks Like a Lady: He looks like a short haired, male version of Kanao.
- Holding Hands: With Touko in the epilogue.
- Identical Grandson: He heavily looks to be a male version of Kanao, his great-great grandmother.
- Kissing Cousins: Is implied to be in a relationship with Touko Agatsuma, the great-granddaughter of Nezuko and Zenitsu, considering his compliments of Touko's beauty, Touko waving excitedly at him with hearts around her, and the cover picture of them walking to school holding hands. Given that Tanjiro and Kanao are his great-great-grandparents, this makes them third cousins once-removed.
Sumihiko Kamado
- Animal Lover: He wants to work at a zoo one day and has a fondness for slow lorises.
- The Baby of the Bunch: He's fifteen and the youngest member of both his immediate and extended family.
- Embarrassing Nickname: His parkour routine to school has earned him the local nickname of "Running Man" from the children. He's not pleased about it.

- The Idealist: He's more idealistic than Kanata. In the final volume extras, he expresses the hope that the demons in his grandma's stories were reborn and are living happily.

- Identical Grandson: He heavily resembles Tanjiro, his great-great grandfather.
- Le Parkour: Upon waking and realizing he overslept, he exits his house (through the window) and races to school, jumping, flipping and vaulting over things (including a police cruiser) along the way.
- Obsessed with Perfect Attendance: Okay, maybe not obsessed. But he wants the perfect attendance award and causes some trouble by parkouring all over town just so he can get to school on time.
- Shared Family Quirks: Inherited a 500 years old trait from his ancestor Suyako, she was an extremely heavy sleeper, sometimes even falling sleep while standing up.
Sumihiko and Kanata's Grandmother

Yoshiteru Agatsuma

- Identical Grandson: He heavily resembles Zenitsu, his great-grandfather (before the latter was struck by lightning).

- Massive Numbered Siblings: In the final extras, He has one older sister and two younger sisters.
- Shared Family Quirks: Fawns over just about any girl he sees, just like his ancestor (and apparently father, if Touko is to be believed in an offhand comment). He's a lot less forward about it, though.
- Tender Tears: Sheds some when reading Zenitsu's journal about his experiences as a demon slayer.
Touko Agatsuma
- All Girls Want Bad Boys: She swoons over Tenma Uzui's handsomeness in spite of her brother pointing his taste for Flipping the Bird and strangling reporters.
- All Women Are Lustful: Inherits Zenitsu's love for anyone attractive of the opposite gender, although she acts less bullheaded about it. She openly lusts over Tenma Uzui in one short scene, and she makes sure to comment on how handsome Kanata is.
- Holding Hands: With Kanata in the epilogue.
- Identical Grandson: She heavily resembles Nezuko, her great-grandmother.
- Kissing Cousins: Is implied to be in a relationship with Kanata Kamado, shown by the hearts around her when she meets up and greets Kanata at school as well as them complimenting each other's beauty, along with them holding hands. Given that Zenitsu and Nezuko are her great-grandparents, this makes them third cousins once-removed.
- Savvy Guy, Energetic Girl: From what we see of her dynamic with Kanata, she plays the bubbly and lively girl to Kanata's stoic and serious guy.
- Thicker Than Water: Despite having no patience for Yoshiteru's antics, Touko does care for him; when Yoshiteru saved her from being run over a truck once before, Touko nursed Yoshiteru back to health, taking care of his injuries.
- Tsundere: Though she hasn't been seen interacting with many other characters, she currently shows a harsh, violent side to her brother and a sweet, doting side to Kanata.
Aoba Hashibira
- Cuteness Equals Forgiveness: Yoshiteru was completely sympathetic to him before he found out he was a man. Unfortunately, his employers did not feel the same way.
- Ditzy Genius: Aoba is the accomplished botanist who discovered the long sought-after Blue Spider Lily, but he accidentally let all the samples that he had gathered and planted wilt.
- Dude Looks Like a Lady: Like his ancestor Inosuke, Aoba has very feminine features and is mistaken for a girl by Zenitsu's descendant, Yoshiteru.
- Fate Drives Us Together: The final volume extras reveal that he befriended Sumihiko because they were crying in the same park. Prior to this, he had no relationship with the descendants of his great-grandfather's close friends.
- Identical Grandson: He heavily resembles Inosuke, his great-grandfather.
- Nature Lover: After receiving backlash for ruining the Blue Spider Lily samples, he is seen sitting outside and expressing a desire to move to the mountains to live alone.
- Older Than They Look: Aoba looks identical to his teenaged ancestor, Inosuke, but extras in the final volume reveal that he's 28 years old.
- Shrinking Violet: Contrast to Inosuke's boisterous attitude, Aoba is rather quiet and doesn't like attention on himself.
Tenma Uzui
- Flipping the Bird: Apparently making crude gestures. His picture actually has him making a face.
- Generation Xerox: He's a white-haired athletic show-off who has a lot of siblings, just like his ancestor.
- Identical Grandson: One can make a case he's the reincarnation of Tengen.
- Massive Numbered Siblings: The final volume states Tenma has 7 siblings, unspecified brothers and sisters.
Giichi Tomioka

- Only One Name: Gotouge curiously only reveals Giichi's given name while confirming him as Giyu's descendant on Vol. 23, despite revealing Sanehiro Shinazugawa's name in full in the very same page. However, the 2nd Databook, does reveal his name in full, Giichi Tomioka.
Kindergarden Teacher
The reincarnation of Gyomei, who now works as a kindergarten teacher.
- The Big Guy: Just like his original incarnation, and Yoshiteru takes notice of his height by staring at him.
- Earn Your Happy Ending: Gyomei's reincarnation gets a second chance in working with kids, now in a world free of demons (and very likely free of people willing to stab him in the back).
Academy Girls
The reincarnations of Kanae and Shinobu, who are students at a local academy.
- Earn Your Happy Ending: They finally get to live normal lives presumably as sisters again. Especially as they are free from demons like, let's say, Doma.
Sanehiro Shinazugawa
- Fate Drives Us Together:
- In the final volume extras, Genya's reincarnation is linked towards Sanehiro as likely just a senpai-kohai relationship, meaning the Shinazugawa brothers are together again despite them possibly not being blood related anymore.
- Also, just like how his ancestor clashed with Tanjiro in the Taisho era, Sanheiro is constantly at odds with Tanjiro's descendant.
- Felony Misdemeanor: Sanehiro furiously pursues Sumihiko in a police car when he catches the boy jaywalking and later reprimands him so brutally Sumihiko cries. Downplayed in that Sumihiko was performing dangerous parkour stunts while jaywalking and had been reported over seventy times.
