Opening Thread

The **Opening Thread** (隙 (すき) の糸 (いと) , *Suki no Ito*?) is an ability to guide the user towards an opponent's opening merely using scent. It helps the user align their Nichirin Sword's blade towards a demon's neck that defines the best place to slash that will behead the demon in a single swing. The ability is known to be used by Tanjiro Kamado during his battles with demons.

## History

During his training with Sakonji Urokodaki, Tanjiro was taught that correct edge alignment in a blade is the key to a clean cut, making emphasis that any deviation or improper technique could potentially break the blade. Taking this lesson to heart when facing the Hand Demon, Tanjiro was able to detect a scent that he can follow to guide his Nichirin sword to his target's neck, allowing him to successfully decapitate it.

Tanjiro utilizes the Opening Thread in his battles with the Hand Demon, Swamp Demon, Yahaba, Kyogai, Rui, and Daki.

## Usage

   Using his extraordinary sense of smell Tanjiro is able to perceive the slight pause in an enemy's movement that creates an opening in which he can strike. The Opening Thread gives Tanjiro a path to follow in order to slice through the neck of a demon. He visualizes the scent as a thread that is attached to a demon's neck at an angle to give him a precise slash. Detecting it is often the most vital part in most of Tanjiro's early battles, as his fights with demons often involve surviving against their onslaught long enough to smell the thread for a successful strike and kill it.

   While it gives Tanjiro a significant advantage to quickly gain the upper hand with a clear path to victory, the thread has a distinct and major flaw. Any change in his blade's direction or movement by a demon will cause the Opening Thread to "snap", forcing Tanjiro to look for another opportunity to attack and detect it again. Yahaba was able to snap the thread by disrupting Tanjiro's footwork on his path to reaching his neck, and Daki was able to snap it by moving too quickly for him to intercept and adapt to her new position.

**Kuina Ubuyashiki** (産屋敷 くいな, *Ubuyashiki Kuina*?) is the Fourth child and third daughter and one of the youngest daughters of Kagaya Ubuyashiki. She currently serves under her older brother, the current head of the Ubuyashiki Household, Kiriya Ubuyashiki.

## Appearance

Kuina has features similar to the rest of her family, light, pale skin with a set of large eyes. She wears a white blunt bob with fringe covering her eyes.

Kuina is usually seen wearing a purple, flower-patterened Edo komon kimono with a white juban under it. She also wears a black obi with a white obiage under it and a pink obijime tying it. She adorns her hair with a short flower headpiece with two beads hanging off it.

## Personality

Kuina displays her strong sense of loyalty and devotion to her brother as the new head of the Ubuyashiki Family and Commander of the Demon Slayer Corps, by being the one to forcefully remind him of his duties as their leader. She even resorts to physical force to remind him of this by slapping him, in order to ensure he did not break down under the stress of his responsibilities.

## History

Kuina was born on June 20th, 1906 AD into the Ubuyashiki family as one of the quintuplets. She is one of the youngest children in the family.

## Synopsis

### Infinity Castle Arc

Kuina helps her brother and sister draw a map of the Infinity Fortress.

## Abilities

**Extraordinary Memory:** During the infiltration of the Infinity Castle by the Demon Slayer Corps, Kuina displays exceptional memory and skill in map making, having successfully mapped out and memorized the entire structure, despite the castle constantly changing. She also provides real-time logistical information to the Hashira alongside her sister, aiding her brother in planning the route to Muzan Kibutsuji's location.

## Trivia

* Kuina was the last member of the Ubuyashiki Household revealed.
* She has good physical abilities. She's called the "slap princess", since she tends to slap people when she overreacts emotionally. Although, she ends up regretting it every time.
* Kuina was described as the 'mischievous' one of the Ubuyashiki quintuplets.
Yatsu

**Yatsu** (やっ, *Yatsu*?) is a minor character of *Kimetsu no Yaiba Reishoki*. He is a civilian that Muzan Kibutsuji bumped into at an alleyway in Asakusa.

## Appearance

Yatsu is a short man with an average posture. He has a big forehead and shoulder-length black straight hair. During his appearance, he wore a yellow vertically striped haori over a light green kimono and a dark green hakama. As he was drunk, his face was flushed with significant red spots on his forehead and cheeks.

## Personality

Yatsu is a stubborn, pushy and aggressive person who displays bully behavior. When he is the one at fault, for instance when he drunkenly bumps into a stranger, he blames the other and isn't satisfied with an apology. He tries to assert dominance over his victim through physical intimidation, by grabbing the victim's shoulders to stop him from leaving the scene, and through verbal intimidation by mocking the victim's clothes and physical appearance. It doesn't seem like he cares that the victim is physically taller than himself. As his older brother is much taller and bigger than most people, he may be more daring to display bully behavior with his brother always protecting him in case it gets physical.

He has a huge disdain for people from higher classes, as evident by his comments on the quality of Muzan's clothes.

He loves drinking, as evident by his suggestion for more rounds at bars. Even when alcohol intoxication caused a poor coordination and a fully flushed face, he tries to fool himself and his companions by not willing to admit being drunken.

## Synopsis

### Asakusa Arc

   In Asakusa, Yatsu had been drinking at bars with his older brother and a woman. They are very drunken when they walk through an alleyway. While dancing around, he suggests to his brother to hit one more bar. When the woman asks him if he is alright, he says he is fine and not even drunken yet.

As he wasn't walking in a straight line, he bumps into a man wearing a fedora by accident. Yatsu gets angry and yells at the man. The man silently apologizes and walks past him. However, this doesn't satisfy Yatsu who grabs the man's shoulder and yells at him to come back. The man says that he is in a hurry and this annoys Yatsu more. He criticises the man's expensive clothes and while walking around to look at the man's face, he laughs at the man's pale skin and claims he looks close to dying.

   This last comment enrages the man internally, but Yatsu doesn't notice and continues taunting the man for not responding to his ridicule. The man suddenly raises a fist and brutally punches the drunkard into the wall, breaking his skull. The woman immediately runs over towards him and announces to Yatsu's older brother that he is not breathing.

## Abilities

As an ordinary human, Yatsu does not possess any additional power or abilities.

## Trivia

* Each crow has 2 names: one childhood name given to them by the current Oyakata-sama, and one they later receive from the Corps member they're assigned to when that time comes.
	+ If the Corps member that the crow was assigned to dies, the crows might be assigned to another member. If such a thing happens, the name given by the former member is respected.
	+ Some crows like to go by the name given to them by the Oyakata-sama while some, such as Tanjiro's crow, opt to give themselves their own name.
* After the battle against Muzan, the crows were allowed to live freely, though sometimes they would come to visit the Ubuyashiki estate as well as the surviving Corps members they were assigned to.
* After the battle against Muzan, Ginko (Muichiro's crow) became weak and sickly. She was comforted by Matsuemon (Tanjiro's crow) and both crows eventually got married.
Hiroshi Shinazugawa

Hiroshi was born to Kyogo Shinazugawa and his wife Shizu. He had 6 other siblings, the oldest two being Sanemi and Genya. Though his father was incredibly abusive to his family, Hiroshi was often protected from his outbursts by his mother. Some time later, Kyogo would meet a violent end by getting stabbed to death in a grudge.

One night, their mother was late to come home. As Hiroshi, Sumi, Teiko, Koto, and Shuya slept, Sanemi decided to go out to look for. Genya stayed behind to watch the rest of them and they woke up shortly afterwards. As they waited for their mother, they became concerned as she had never been so late before, with Genya trying to ease their worries and asking them to go back to sleep.

A loud knock then rang from the front door, leading Hiroshi, Sumi, Teiko, and Shuya to run and greet their mother. Despite Genya's warning that the figure outside may not be her, the door broke open. Their mother, who had transformed into a demon, entered and killed the four instantly.

Toyo

## Familial Status

**Toyo** (豊, *Toyo*?) is an udon street vendor who lives in Asakusa, Tokyo.

## Appearance

Toyo is a man of average height and build, with a bald head and eyes he usually keeps closed. He wears a dull yellow-and-black striped kimono, light pants, and dark shoes. In his first appearance, he was also smoking a kiseru.

## Personality

Toyo is very passionate about his udon, as he was visibly agitated towards Tanjiro Kamado for discarding his bowl without eating any of it. However, once Tanjiro returned, ordered two more bowls, and gobbled them down, Toyo was pleased and thanked him for his business.

## History

Toyo was born and raised in Asakusa. At some point in his life, he opened an udon handcart at the edge of Asakusa, as he loved the city and wanted to stay there.

## Synopsis

### Asakusa Arc

During Tanjiro's second mission as a Demon Slayer, he was tasked with investigating a demonic presence in Asakusa. Overwhelmed and disoriented by his inexperience in modern cities, he quickly fled the busy, bustling center and stopped at an udon shop owned by Toyo. As he ordered an udon bowl and prepared to eat, he detected the scent that was present in his home that day when he'd found his family massacred. He stood up in shock, inadvertently causing his food to drop to the ground, and pursued the scent.

When Tanjiro returned, Tojo angrily lectured him for dropping his udon without even eating it and the boy decided to get another one as compensation. When Toyo demanded that Nezuko eat his udon too and tried to get her to remove the bamboo muzzle in her mouth, Tanjiro decided to order a second bowl in her place. Toyo then watched with surprise as Tanjiro proceeded to gobble down both bowls of udon in almost no time at all, before being thanked for the meal. As the Kamado siblings departed his shop, Toyo happily waved them goodbye and thanked them for doing business with him.

## Abilities

As an ordinary human, he doesn't posses any additional powers or abilities.

## Trivia

* Toyo can also make soba as well as udon. He says he will never teach anyone how to make the stock.
Kaburamaru

**Kaburamaru** (鏑 (かぶら) 丸 (まる) , *Kaburamaru*?) is a snake and animal guide belonging to the Serpent Hashira, Obanai Iguro. Kaburamaru is always seen wrapped around Obanai’s shoulder.

## Appearance

Kaburamaru is a small white snake, possibly a rat snake, with reddish pink eyes and long hexagonal scales that adorn his body. He appears to be an individual of his species with albinism. He possesses two long fangs that, as well as the shape of his head, indicates that he is most likely venomous.

## Personality

   Kaburamaru seems to be a rather intelligent animal, not just an ordinary snake. In most situations, he is usually seen flicking his tongue to sense his surroundings while coiled around Obanai's neck. He also appears to be of similar personality to Obanai himself, as seen when he angrily hissed at Suma for chiding the Serpent Hashira for his late arrival to Yoshiwara. He also seems to be attached to Mitsuri Kanroji, as she was seen stroking Kaburamaru in the past, and when he seemingly shed tears during her death.

After Obanai's death, Kaburamaru appears to have mellowed out somewhat, as he was shown being entrusted to Sanemi Shinazugawa and later Kanao Tsuyuri, whereas he was initially always with Obanai from the beginning. He is also seen smelling Tanjiro Kamado's face in curiosity.

## History

Kaburamaru was born on May 27th, 1905 AD, during the Meiji era on Hachijojima Island where the Iguro Clan resided.

   During his life in captivity to become a sacrifice to the Serpent Demon in the same year of 1910 AD, Obanai found a five-month-old Kaburamaru had slithered into his cell. Being the only living thing that didn't want him dead at the time, he took the young snake in as a companion. Once he made his escape, he had the snake with him when he fled. The two would end up being rescued shortly after by the 46-year-old Flame Hashira of then, Shinjuro Rengoku.

Kaburamaru became a permanent companion to Obanai, always coiled around him during his career as a Demon Slayer and eventually as the Serpent Hashira in the year 1912 AD.

## Abilities

### Overall Abilities

Kaburamaru is far more intelligent than the average snake, as he is capable of understanding human language and following commands. He also serves as an animal guide for Obanai, who is himself partially blind, being able to put his own sensorial abilities to use and relay the information to his owner, granting him greater perception. Kaburamaru also seems to be exceptionally well-trained as he was not only capable of discerning the many lethal attacks of Muzan Kibutsuji himself, he was also intelligent enough to grab one of Yushiro's paper talismans in mid-air in between Muzan's attacks, feats that left the Demon King flabbergasted that an animal like him could detect him so well. Most impressively, Kaburamaru was able to survive the encounter with the Demon King, completely unscathed, despite all the carnage unleashed by Muzan's rampage.

## Trivia

* Obanai considers Kaburamaru more of a friend than a pet.
	+ After Obanai's death, Kaburamaru is entrusted to Kanao Tsuyuri by Sanemi.
* As he is a rat snake, Kaburamaru's length is 180 cm.

## Etymology

* Tenma's surname is completely identical to his ancestor Tengen Uzui: containing the Man'yogana for the kana "U" (宇 (う) , ***"U"***?) along with the Kan'yō-on'yomi reading of the kanji for "marrow, pith" (髄 (ずい) , *zui*?). Like his ancestor, Tengen, his given name also contains the Kan-on'yomi reading for "heaven" (天 (てん) , *ten*?) and the Go-on'yomi for "full, enough" (満 (ま) , *ma*?).
	+ His first name when combined means Tenman-gū (天 (てん) 滿 (まん) 宮 (ぐう) , ***Tenman-gū***?), a shrine in Japan worshipping Sugawara no Michizane, a poet and scholar from the Heian period.

## Appearance

Tenma is a very good-looking person. He bears a striking resemblance to his flamboyant predecessor: having the same white hair, the same eye shape, the same eye color, and even the same receding eyebrows! Also, his skin shade is slightly tanned due to his participation in the Olympics.

## Personality

Tenma seems to be a playful attention-seeking person. In the news picture about his gold medal win, he is seen doing an akanbe (an eyelid pull) accompanied by sticking his tongue out, while holding his medal towards the camera.

He is also noted to be rude, often flashing his middle finger and choking reporters.

## Synopsis

As the Agatsuma siblings make their way to school, Toko Agatsuma looks at a news article on her phone, which shows that Tenma had just won a gold medal in gymnastics for Japan. Toko is totally smitten by Tenma, but her brother Yoshiteru Agatsuma says that Tenma was rude and gives examples of his behaviour. Toko defends Tenma and he wondered aloud if one can get away with anything just because he was good looking.
Shoichi

**Shoichi** (正一, *Shōichi*?) is a young boy saved by Tanjiro Kamado and Zenitsu Agatsuma when they approached him to help his older brother, Kiyoshi, escape from the Drum House. He also has a younger sister, Teruko.

## Etymology

* Shoichi's name contains the kanji for "straight, right, proper, regular, standard" (正, *sho*?) and "one" (一, *ichi*?).

## Appearance

Shoichi is a short young boy of around 8-10, with black spiky hair and hazel eyes with a thick black border.

Shoichi wears a blue haori over a light green iromuji kimono with a white juban under it.

## Personality

While his personality is not fully elaborated on, one can assume he is a loyal brother as he decides to follow his older brother to rescue him after he was kidnapped by a demon. He has also shown a protective side while interacting with his younger sister. It can be surmised that Shoichi is braver than average, as he decides to follow the two Demon Slayers, Tanjiro and Zenitsu, into the Drum House. Even when separated from the others with Zenitsu, he shows more courage than the Thunder Breathing user.

## History

While not much is known about his personal history, Shoichi came from a family of presumably three kids, with him being the middle child.

## Trivia

* Zenitsu is under the false assumption that Shoichi is a strong warrior after he lost consciousness inside the Drum House while being accosted by the Tongue Demon.

Takaharu

**Takaharu** (高晴, *Takaharu*?) is the grandson of the villager who taught Inosuke how to speak.

## Appearance

Takaharu is a young man in his late teens or early to late twenties, he has a shaved head ⁠— similar to the haircut Shigeru has ⁠— and wears a white rope as a headband in the style of hachimaki. He also has distinctly large earlobes as well as long eyelashes.

In the chapter, he wears baggy light colored trousers beneath a dark jinbei-styled kimono, and can be seen carrying a medium sized razor hoe.

## Personality

Takaharu has an extremely rambunctious personality and foul mouth due to the manner in which he was raised. When he encounters Inosuke as a child, he scares him off in a vulgar manner, and calls his grandfather a dumb old man for feeding him, mistaking Inosuke for a weird animal.

During their multiple encounters he constantly scolds his grandfather for continuing to care for Inosuke, but does so in order to protect his aging grandfather.

After he realizes that Inosuke can talk, he becomes fearful of him and calls him a monster and ultimately allows him to do as he pleases in his home.

## History

Not much can be said about Takaharu's history except that he lives with his grandfather and works during the day.

## Synopsis

Takaharu is first introduced when he arrives home from work one day to discover his aging grandfather feeding a strange animal outside, unknown to him that this animal was actually a child ⁠— Inosuke Hashibira ⁠— wearing a boars head. He scares Inosuke off and warns his grandfather not to feed him anymore in fear of its parent returning.

Later on when Takaharu returns home on a different day, he discovers his grandfather reading the "Ogura Hyakunin Isshu" (小倉百人一首, ***"Ogura Hyakunin Isshu"***?) to Inosuke on his lap. Takaharu becomes enraged, scaring off Inosuke and scolds his grandfather again. When his grandfather discovers Inosuke's name on his sash, Takaharu becomes enraged and tells him there's no way a boar can have a name.

He tries to scare Inosuke off again but is kicked in the face and yelled at by the child. Inosuke tells him to shut up and let him do as he pleases, which reluctantly scares Takaharu into allowing Inosuke to do as he pleases.

## Abilities

* As an ordinary human, Takaharu does not posses any powers or abilities.
Blue Spider Lily

The **Blue Spider Lily** (青い彼岸花, *Aoi Higanbana*?) is a mythical flower. It is an important ingredient of a medicine for Muzan Kibutsuji's treatment and the reason he turned into a demon and by Yuzuriha Kijin three years earlier to willingly turn herself into a demon.

## Overview

The Blue Spider Lily is a mythical and enigmatic flower that is described to be a spider lily that is blue in color instead of red. The flower only blooms at daytime for two to three days a year, after which it closes back up, resembling a large horsetail weed. In some cases, depending on the climate, the Blue Spider Lily doesn't even bloom at all. This explains why Muzan Kibutsuji never found it despite searching all over Japan for centuries: he was hindered by his inability to go out during the day.

This flower has medicinal properties, being used to cure Muzan of an unknown illness that would've caused him to die before turning 20, albeit the medicine was in its experimental stage and thus extremely difficult to replicate. The Blue Spider Lily medicine was also the cause behind Muzan's demonification, granting him a strong body and changing his blood to have transformative properties, enabling Muzan to create more of his kind as well as hold dominion over them. However, this medicine also had the side effect of causing Muzan to disintegrate into ash if he was exposed to sunlight as well as a craving for human flesh. It is also implied that the Blue Spider Lily can nullify a demon's weakness to the sun if it’s consumed, which is the reason Muzan was spending centuries searching for the flower. This is proven as well due to the fact on how Yuzuriha has slight sunlight resistance.

## Trivia

* Kie Kamado knew where the Blue Spider Lilies bloomed, and showed them to Tanjiro Kamado when he was very young. This is why he was vaguely able to briefly recall them when his life was flashing before his eyes during the battle against Rui.
* The flower doesn't bloom every year and did so only for a very limited time. Out of the six siblings, Tanjiro was the only one to witness them.
* The Blue Spider Lilies bloomed in the same spot where Yoriichi Tsugikuni buried his wife Uta.
* After self-demonizing herself, Yuzuriha decided that in order to remain the only all-powerful demon, she intentionally destroyed most of all the Blue Spider Lilies in Japan, leaving only a few to grow in the Kanto region, the same place Muzan's doctor and in future, Tanjiro Kamado, live.
* The Blue Spider Lily is a flower that does not exist in reality. However, the Red Spider Lily is an important flower in Japanese folklore, believing to guide the dead to their next reincarnation. They are also believed to grow upon the shore of the Sanzu River, the river of the dead in Japanese folklore, and all who die must traverse the width of it. It is possible the author intends for the Blue Spider Lily to represent the antithesis of the Red Spider Lily (salvation), which would be damnation.
Serpent Breathing

**Serpent Breathing** (蛇の呼吸, *Hebi no Kokyū*?) is a Breathing Style derived from Water Breathing.

## Overview

Serpent Breathing is a Breathing Style that mimics serpents/snakes, specifically their slithering motions, and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques and forms focuses on twisting and bending the sword like how a serpent slithers, the attacks are not direct and constantly meander which can ultimately strike anywhere. Users of Serpent Breathing also visualize themselves seemingly manifesting white serpents that accompany them when unleashing its techniques.

After the death of Muzan Kibutsuji, Serpent Breathing, like Sun Breathing and the other Breathing Styles, became a ritual dance known as the **Hebikami Kagura** (蛇神 神楽, *Hebikami Kagura*?, lit. "Dance of the Serpent God") offered to the Japanese deity of fertility who is also one of the harvest deities, Ugajin. This was done by an individual in the Demon Slayer Corps.

## Weaponry used with this Breathing Style

Since this technique is currently known to only be utilized by Obanai Iguro, it can only be used with a twisted blade that is similar in appearance to an Indonesian Kris Sword, with the sword's shape modeled into the bodily structure of a snake.

## Techniques

Serpent Breathing has 5 known techniques and forms at minimum.

* **First Form: Winding Serpent Slash** (壱ノ型: 委蛇斬り, *Ichi no kata: Idagiri*?) - The user moves like a slithering snake and releases several slashes in a winding pattern.
* **Second Form: Venom Fangs of the Narrow Head** (弐ノ型: 狭頭の毒牙, *Ni no kata: Kyōzu no Dokuga*?) - The user dashes behind their opponent at blinding speed and aims to swiftly slice off their head.
* **Third Form: Coil Choke** (参ノ型: 塒締め, *San no kata: Toguro Jime*?) - The user circles around their opponent while using their sword to slice them from all directions.
* **Fourth Form: Twin-Headed Reptile** (肆ノ型: 頸蛇双生, *Shi no kata: Keija Sōsei*?) - The user leaps forward and performs a horizontal slash that slices through the target.
* **Fifth Form: Slithering Serpent** (伍ノ型: 蜿蜿長蛇, *Go no kata: En'en Chōda*?) - The user curves their sword in multiple directions and slices their opponent, making it capable of decapitating multiple enemies at once.

He had two pairs of eyes, one large and cat-like of a green color and the other more squinted and set above the first, their irises red. His most notable features were his extremely long tongue and the navy blue arrows that patterned his nose and forearms, a large blotch of a similar color on each temple.

The Tongue Demon wore nothing above his waist, under which he sported only the bottom half of a patterned knee-length yukata.

## Personality

The Tongue Demon, as with many others of his kind, was a ruthless being who seemed only to care about eating any and all humans that crossed his path. He appeared to be somewhat unintelligent, as he often talked to himself and repeated words when speaking as well as slithered around on the floor rather than walking.

## History

Before Tanjiro Kamado and Zenitsu Agatsuma entered the mansion, the Tongue Demon discovered the manor's demon Kyogai had found a boy, Kiyoshi, which he had intended to devour for his Marechi blood. They were joined by a third demon and the three fought over who had the right to devour the boy.

## Synopsis

   While crawling around the Tsuzumi mansion, the Tongue Demon happened upon Zenitsu, a member of the Demon Slayer Corps, and Shoichi, the younger brother of his desired prey Kiyoshi. He startled the two with his unusual appearance and long tongue, before chasing them into an empty room. Overwhelmed by the creature's grotesque appearance and his fear of demons, Zenitsu suddenly lost consciousness, to the Tongue Demon's confusion.

   He attempts to grab Shoichi with his tongue but unexpectedly has the tip of it sliced off, which the demon fails to see. Zenitsu suddenly arose and began to breathe, which confuses and scares the Tongue Demon, who notes that his aura has changed. In an instant, the Demon Slayer beheads the demon with his **Thunder Breathing, First Form: Thunderclap and Flash**. The demon's head rolls next to Zenitsu, who becomes startled by the demon's unexpected death upon snapping awake.

One night, as Shuya, Sumi, Teiko, Hiroshi, and Koto slept, Sanemi and Genya were concerned that their mother had not come home yet. As Sanemi ventured out to find her and Genya stayed behind, Shuya awoke with the rest of his siblings.

Eventually, a loud knock rang from the door, leading Shuya to call out to his siblings that their mother had come home.
