**Yoriichi Tsugikuni** (継国 縁壱, *Tsugikuni Yoriichi*?) was the main protagonist of *Kimetsu no Yaiba Narratives: Sengoku Tales*, and currently the posthumous overarching protagonist of the entire *Kimetsu no Yaiba Narratives anthology* on Wattpad. He was a legendary Demon Slayer who lived nearly 500 years ago during the Sengoku Period (the Golden Age of Demon Slayers), as well as the strongest Demon Slayer to have ever existed along with being the very first Sun Hashira (日柱, *Hi Bashira*?). He was also the inventor of Breathing Styles, being the one who created the first ever Breathing Style that would eventually become the Hinokami Kagura used by Tanjiro Kamado and members of the Kamado Family.

Yoriichi is the younger twin brother of Michikatsu Tsugikuni, who later became the demon Kokushibo and joined the Twelve Kizuki.

## Etymology

Yoriichi's family name is composed of the Kun'yomi reading of the kanji for "to inherit, succeed" (継, *tsugi*?) and "country, kingdom" (国, *kuni*?). His given name contains the Kun'yomi reading aswell and means "fate, destiny" (縁, *yori*?) and the traditional daiji for "one" (壱, *ichi*?).

## Appearance

Yoriichi is a tall man with a muscular build, fair skin, maroon eyes, and long spiky hair with red tips that he kept in a ponytail. He has a similar overall appearance to his twin brother Michikatsu, but unlike him, he was slightly more slender, had shorter bangs, and wavier hair than him. Yoriichi is always seen with an aloof and solemn look on his face, rarely showing emotion.

Yoriichi wore a red haori over a very pale orange-colored nagagi kimono with a black umanori-styled hakama, a pair of zōri with red straps and white tabi socks, with a Nichirin Sword carried at the left side of his waist, conventional to most Demon Slayers. He sported hanafuda earrings created by his mother as charms when he was thought to be deaf; he later gave them to his friend Sumiyoshi, who then passed the earrings down to his descendants and eventually Tanjiro as well.

## Personality

    Yoriichi was known to be a calm and respectful individual who wore a solemn and reserved expression at all times, rarely showing outbreaks of emotion. Generally, Yoriichi had a matching low and serene disposition, evident when he killed demons without changing expression or when Muzan was caught off guard by his immense skill because he appeared unassuming. Because of his gentle disposition and unchanging facial expression, most could not tell what he was feeling: the only person who could read his feelings without difficulty was his wife Uta. He was also extremely humble, seeing himself as just another man and no one special despite his godly attributes; an example being the time he performed the Sun Breathing's forms for Suyako at her request and almost seemed embarrassed afterwards. Yoriichi was also noted by his brother to always have had faith in the future and was confident that despite the immense power of the Demon Slayers after they started using Breathing Styles, a generation would emerge that would surpass their own.

    Despite being mostly nonchalant, he does experience strong emotions; he grieved the loss of Uta and their unborn child for ten straight days and was driven to tears seeing the joy Sumire showed at the simple act of being lifted up. He also smiled warmly and expressed gratitude to Sumiyoshi after his friend told him his life was not worthless and promised to preserve his Sun Breathing forms through his descendants. Yoriichi is also very kind, shown when he was on the way to fetch a midwife in preparation of the birth of his child, only to stop and help an old man he met along the way reach his dying son.

As a child, it was shown that Yoriichi adored and idolized his older brother, Michikatsu, even declaring that he would support his brother's dream of becoming the strongest samurai in the land, and Yoriichi himself would become the second strongest. Even in his childhood, he was also extremely reserved and quiet, even being thought deaf by his family for seven years as he never spoke.

Yoriichi is shown to love his family greatly: he cared for his ailing mother when no one else knew she was ill and protected his father by not telling anyone about how he berated him as a child. He was particularly fond of his older twin brother, evident when he kept the flute Michikatsu gave him before he ran away from home all the way till his death. When he met him after sixty years, the latter having embraced his new life as a demon. Yoriichi was deeply devastated and saddened by what his brother had become, expressing how heart-wrenching the sight of his brother was and even teared up. Still, he attempted to kill Michikatsu himself in order to stop him as a traitor of the Demon Slayer Corps.

## Abilities

### Overall Abilities

    Yoriichi is the strongest known Demon Slayer in history, being born with the Demon Slayer Mark, Transparent World, and Selfless State, as well as possessing a god-like physique and innate swordsmanship talent, only seconded by Dumisani Mavundla. As a seven-year-old child who has never picked up a sword before, he was able to defeat a trained sword instructor effortlessly and he was referred to as a miraculous prodigy beyond compare. After training as a Demon Slayer, Yoriichi could defeat multiple demons to where his older brother stated that he as a child couldn't even compare to him as an adult.

He was the only one among the Demon Slayer Corps was able to corner Muzan Kibutsuji and overpowered him in an instant and had him on the verge of death until he managed to escape on this occasion. Despite having avoided death, Muzan was deeply scarred by Yoriichi's encounter, referring to him as a monster, and even the sight of his earrings made him tremble in shock, while mere memories of Yoriichi caused the bodies of other demons who have never met him to tremble.

Shortly before his death of at least 85 years in age, he battled his older twin brother, Kokushibo who turned into a demon. Despite both his advanced age and apparent blindness, he quickly gained the upper-hand in the battle with a single move, slitting his throat before he finally died standing up, unscathed. Kokushibo himself admits that if Yoriichi launched a second swing before dying, he would have killed him, while commenting Yoriichi's power was still in his prime.

Even after centuries pass, Takanori Hoshimiya, the Taisho era Stellar Hashira, says that his skill is only nigh-unparalleled in terms of Taisho era standards, and that Yoriichi will always remain the strongest demon slayer in history. This shows Yoriichi's overwhelming power that even the one of the strongest humans in the Demon Slayer Corps alive still acknowledges him after his death in 1517.

**Genius Intellect:** As a child prodigy, Yoriichi is extremely intelligent. Despite not speaking for most of his childhood, his first words were very clear and pronounced. He also displayed maturity beyond his age as he noticed her mother's illness and helped her all the way till her death. As another testament to his keen intellect, he could immediately use the Transparent World in combat despite never fighting before, being able to intuitively figure out that the lungs of person will expand before they attack and that he needed to watch their bone movement, muscle contraction and blood flow, which he used to his advantage instantly in the midst of battle.

Even with just the knowledge of how to hold a sword properly and go into a stance, he was able to instantly overpower a trained sword instructor, causing him to go unconscious and inflicting many injuries all over his body. His unique intellect brought about the "Golden Age of the Demon Slayers" as he invented the Breathing Styles and modified the original Breathing Technique to suit the abilities and individual strengths of others. Furthermore, he was able to surmise that Muzan's weaknesses were his 12 organs and created an entirely new technique in that split second to overwhelm him.

### Physical Abilities

    **Immeasurable Speed & Reflexes:** Yoriichi possessed unparalleled levels of speed that surpass all other characters in the series, including that of the Demon King, shown when he was able to dodge every attack that Muzan launched at him and near-fatally injure Muzan with one move, despite the demon's own immeasurable speed and strength. Even when Muzan divided himself into 1,800 flesh pieces to escape, Yoriichi still managed to reduce the number down to 300 in mere seconds.

Later, when Yoriichi was in his 80s he could blitz Kokushibo, Muzan's strongest subordinate, nearly severing his neck instantly, despite Yoriichi telling him when he will strike. As another testament to his godlike movement speed, Yoriichi Type Zero, the robot doll modeled after him used by Demon Slayers to train, was built with 6 arms because 2 arms alone couldn't replicate Yoriichi's movements.

**Immeasurable Stamina & Endurance:** Even as a seven-year-old child, Yoriichi could run for a whole day without rest, he even remarked he didn't feel the least bit enervated. His vitality is also beyond peak-human level, being able to survive without food or water for 10 whole days when he was embracing his dead wife. Moreover, Yoriichi lived to his 80s without his power waning in the slightest, as shown when he instantly outmatched Kokushibo during their final confrontation.

**Immeasurable Strength:** Yoriichi possesses tremendous levels of physical strength possibly beyond that of nearly all other Demon Slayers in existence. As a child, he could knock out a grown man with inclined physical abilities with a wooden blade, even causing extremely severe bruises the size of fists. When he was an adult, he was able to effortlessly slice off the neck of Muzan Kibutsuji, the most fortified body part of the strongest demon in existence.

### Demon Slayer Abilities

**Demon Slayer Mark:** Yoriichi is the progenitor of the Demon Slayer Mark, being born with it, possessing the tremendous physical abilities granted by its effects all throughout his lifespan. Unlike all other marks users in his era, Yoriichi was able to defy fate and lived to about 85 years of age. It is presently unknown why Yoriichi is immune to the Mark's effects, but it's presumably because he was the first one ever to have it and born with it naturally, unlike all other mark bearers who must train to attain it.

* **Bright Red Nichirin Sword:** Yoriichi is the first person ever to be able to turn his Nichirin Sword into a bright red color as he was born with the mark that presumably gave users the ability to turn their blade bright red as well. When fighting, Yoriichi can dye his black sword to bright red at will, letting him hamper the enhanced regeneration of demons, even Muzan's instant regeneration, burning him at a cellular level, leaving scars on his body for hundreds of years. It has also been noted by Muzan himself that Yoriichi's bright red blade was far more effective than those of the current generation Hashira and Tanjiro, as Yoriichi could completely negate Muzan's near-absolute regeneration for a short period of time while the modern era Demon Slayers can only slightly slow it down, despite the fact that Muzan was in a much weaker condition because of the Anti-Kibutsuji Drug.
* **Transparent World:** Yoriichi has access to the Transparent World since birth, and could use it with surprising proficiency, evident when he could watch for lung expansions and muscle contractions within a person and surmise when to strike them. This ability also granted him an advantage against Muzan, allowing him to find his weaknesses instantly and overwhelm him.

**Selfless State:** During their confrontation, Muzan noted that Yoriichi emanated absolutely no sense of drive, hatred, anger, fighting spirit, animosity or even bloodlust despite being in mid-battle against him, rendering it practically impossible for Muzan to detect him, predict his movements or gauge how powerful he was with his senses. This gave Yoriichi an edge in battle against Muzan as he underestimated his strength, a mistake that shook the Demon King to this day.

### Supernatural Abilities

**Extrasensory Perception:** Outside of the sixth sense granted by the Transparent World which allowed him to see the inner workings of a person, Yoriichi also has extremely honed sensory abilities able to detect things outside the normal range of perception. Like most high-level Demon Slayers, Yoriichi would be able to discern the aura of demons from humans while also be able to tell the strength of his enemies at a glance. During Yoriichi's first encounter with Muzan, he could immediately tell that, by destiny, he was born into this world to defeat him. Yoriichi was also able to accurately sense Demon King's aura, which he describes as magma erupting from a volcano.

## Fighting Style

    **Unparalleled Swordsmanship:** Yoriichi is the greatest swordsman to have ever lived. Even as a seven-year-old child with no training, he was capable of easily defeating a trained swordsman the very first time he ever picked up a sword, striking him in multiple areas across his body faster than the eye can process. His swordsmanship was so tremendous that a battle doll modelled after him had to be made with 6 arms wielding katanas and utilizing 108 techniques to even attempt to imitate Yoriichi's skills, and even then, the doll was still vastly inferior compared to him. His swordsmanship easily overwhelmed the Demon King, Muzan Kibutsuji and he would have killed his twin brother, Kokushibo, the strongest swordsman in the current era, if he didn't die of old age.

### Breathing Style

**Sun Breathing** (日の呼吸, *Hi no Kokyū*?) Created by Yoriichi himself as the original Breathing Style which all other subsequent styles would be modeled after and was later replicated by Sumiyoshi who called it **Hinokami Kagura** (ヒノカミ神楽, *Hinokami Kagura*?). Yoriichi was incredibly proficient in his Sun Breathing, being able to take down demons effortlessly and even overwhelm the Demon King and strongest Upper Rank. Tanjiro remarked that when Yoriichi performed the techniques of Sun Breathing, the forms were so strikingly beautiful and breathtaking, he looked more like a spirit than a man.

#### Techniques

* **Dance** (円舞, *Enbu*?) - The user performs a singular downwards vertical slash in an arcing motion.

* **Solar Heat Haze** (飛輪陽炎, *Hirin Kagerō*?) - The user rushes forth, now attempting to deliver a strike seemingly enveloped in a heat-haze, masking the true length and location of the blade to deliver an unexpected strike.
* **Beneficent Radiance** (輝輝恩光, *Kiki Onkō*?) - The user spirals into the air four times whilst swinging their sword to perform a singular attack upwards to strike the target once.
* **Sunflower Thrust** (陽華突, *Yōkatotsu*?) - The user performs a singular thrust utilizing the tip of their blade to strike the target.
* **Sun Halo Dragon Head Dance** (日暈の龍・頭舞い, *Nichiun no Ryū Kaburimai*?) - The user assumes a high stance, before unleashing a number of consecutive slashes in a fluid motion in the form of a Japanese dragon made of solar flames. This technique is capable of decapitating multiple targets at once.

* **Thirteenth Form** (拾參ノ型, *Jū San no kata*?) - The user continuously performs all twelve forms of Sun Breathing in repetitive succession to increase the accuracy and agility of its movements, and attacks. This form was created solely for the purpose of killing Muzan Kibutsuji, since the repetition of all twelve forms aims to destroy Muzan's twelve vital organs (seven hearts and five brains) that move freely inside his body.

## Equipment

**Standard Nichirin Katana:** As a Demon Slayer, Yoriichi carries around a standard sized and shaped Nichirin katana that is deep black in color, but changes bright red during combat. His katana's hilt is circular shaped with 4 slight indentations, with a black center and a golden border. Although he is a member of the first generation of Hashira, Yoriichi's katana doesn't have the words **Destroyer of Demons** (惡鬼滅殺, *Akki Messatsu*?) like his peers but had the words **Slay** (滅, *Metsu*?) engraved on both sides. Along with his katana, Yoriichi also carries a standard sword sheath which had a gold colored mouth and cap. It is implied that his katana was discovered after his death and hidden in the battle doll made in his image, Yoriichi Type Zero. His sword would be used centuries later by Tanjiro Kamado before and during the final battle against Muzan Kibutsuji.

## Trivia

* The bag in which Yoriichi carried his brother's flute may have possibly been made of the cloth of his late wife's kimono, as the cloth patterns between the bag and kimono are quite similar.
* There are times where Uta believed he was the spirit of "Kṣitigarbha/Jizō" (地藏, *Jizō*?) (a bodhisattva known for this vows of instruction of the Six Worlds of Saṃsāra and not attaining buddhahood until all Naraka hells are empty) or "Zashiki-warashi" (座敷童子, *"Zashiki-warashi"*?), a young-childlike yōkai who protects households.
* The relationship between Yoriichi and Michikatsu parallels the mythology of the Shintō deities Amaterasu and Tsukuyomi, respectively. Amaterasu is the most sacred of Shintō deities, the sun goddess. Tsukuyomi, the moon god, is her former husband and brother. After Tsukuyomi killed Ōgetsu-hime/Ukemochi, the Shintō deity for food, Amaterasu refused to ever look upon him again, moving to another part of the sky and beginning the cycle of day and night. Like the deities, the siblings also feud and have chosen different paths (that of the Demon Slayer and the demon), developing their respective breathings of the sun and moon.
* After his mother gave him his signature Hanafuda earrings, Yoriichi realized he received them because his family had considered him deaf. His mother Akeno was the first person he had ever spoken to; to confirm that he wasn't deaf, he said, "I can hear you".
* Although he is normally quiet and calm in nature, he chatted frequently after getting along with the Hashira of the Sengoku Era. Despite their initial anger for his brother's transformation, some of the Hashira would continue to speak with Yoriichi after his banishment, due to their close friendship.
* Yoriichi and his wife Uta reincarnated into modern time iand became a very happy couple with kids.

## Yoriichi's view of the other Hashira

* *"Kind, and fun to be with."* - Flame Hashira.
* *"A reliable man, but he does not understand how to talk to women."* - Thunder Hashira.
* *"We recovered from injuries together."* - Stone Hashira.
* *"A respectable, dependable older brother." -* Moon Hashira.
* *"An eager and hardworking, yet arrogant student of mine."* - Stellar Hashira.

## Quotes

* (To Sumiyoshi Kamado) "*Sumiyoshi... those who master their trade all arrive at the same place. Even if the times change or the way to that place changes they are certain to reach the same place. You seem to think I'm someone that's special but I'm not. I cannot protect anything that's important to me and I was unable to accomplish even one thing that I should have in this life. I am a man without any value*."
* (To Kokushibo) "*My brother... we are not that great. We are merely a fragment of humankind's long, long history. At this moment, those whose talent will surpass ours are uttering their first cries. They may come to reach the same place. There is no need to worry. We can draw the curtain of life closed without unease at any time. Does that not exhilarate you? Brother? Someday... the children now being born will surpass us and ascend... to even greater heights*."
* (To Kokushibo) "*My brother, is your dream to become the strongest samurai in the land? I want to be like you. I... want to become the second strongest samurai*."
* "*My dream was to live a quiet life with my family in a small house where we would sleep side by side. I would be close enough to see the beloved faces of my wife and child and close enough to reach out and take their hands. That would have been enough. But even that... did not come true. (Because) demons exist in this beautiful world*."
* "*The Demon Slayers defeated demons, one after the next. When demons killed my elder brother's subordinates, he too became a Demon Slayer and lent us his strength. Soon after, I found the demon's progenitor. And in that moment... I knew that I had been born for the purpose of defeating him*."
* (To Muzan Kibutsuji) "*What is the value of a life to you?*"
* (To Sumiyoshi Kamado) "*I think I was born with special strength for the purpose of defeating Muzan Kibutsuji. But I was lacking. In the end, I failed. Because of that, many more people will die. And that pains me*."
