Name

(“Yoriichi Tsugikuni”)

Who Yoriichi Tsugikuni is

(“Yoriichi Tsugikuni (継つぎ国くに 縁より壱いち, Tsugikuni Yoriichi?) is a major protagonist. He is a Demon Slayer who lived nearly 500 years ago during the Sengoku era. He was the most powerful Demon Slayer to have ever existed. He is also the inventor of Breathing Styles, being the one who created the first ever Breathing Style, Sun Breathing, 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 a demon and joined the Twelve Kizuki.”)

Appearance

(“Yoriichi is a tall man with a lean 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 mostly expressionless, though sometimes a little solemn and aloof. 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 Kamado, who then passed the earrings down to his descendants and eventually Tanjiro as well.”)

Personality

(“Yoriichi was 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 offguard 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.[5] He was also extremely humble, seeing himself as just another man and no one special despite his extraordinary abilities; 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 appearing mostly nonchalant, he experiences emotions like any other person; 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 as it represented the very same joy that his unborn child was tragically denied of. 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. Additionally, despite his own immense skill and strength, he was not above admitting his own weaknesses, acknowledging that even a scratch by Muzan could kill him and experiencing fear for the first time in his life.”)

Personality [2]

(“As a child, Yoriichi looked up to his older brother Michikatsu. Michikatsu's dream was to become the strongest samurai in the land, so he said that he would become the second strongest. Even in his childhood, he was extremely reserved and quiet, even being believed to be deaf by his family for seven years as he never spoke. Yoriichi 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, even when his father did not love him. He loved and respected his older twin brother and he kept the flute Michikatsu gave him before he left 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 by what his brother had become and cried. Nonetheless, he attempted to kill Michikatsu in order to stop him as a traitor to the Demon Slayer Corps.”)

Abilities and info

(“Yoriichi is the strongest Demon Slayer in history, being born with the Demon Slayer Mark, access to the Transparent World, and Selfless State, as well as possessing a physique polished to the highest caliber and innate swordsmanship talent. 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. Yoriichi using the Thirteenth Form against Muzan Yoriichi overpowering Muzan, the Demon King, with a single move. He alone among the Demon Slayer Corps was able to corner Muzan Kibutsuji and overpowered him in an instant, having him on the verge of death until he barely managed to escape. Despite having avoided death, Muzan was deeply scarred by that encounter, referring to him as the true "monster" between the two of them, 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.”)

Abilities and info

(“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 a 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 seven hearts and five brains and created an entirely new technique in that split second to overwhelm him.”)

Demon slayer abilities and info

(“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 users of the Marks 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 is 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.[19] * Bright Red Nichirin Sword: Yoriichi is the first person ever to be able to turn his Nichirin Sword into a bright red color, and he subsequently gave other users the ability to turn their blade bright red as well. When fighting, Yoriichi can turn his normally black sword bright red at will,[20] allowing him to hamper the enhanced regeneration of demons, even Muzan's instant regeneration,[8] burning him at a cellular level and leaving scars on his body for hundreds of years.[21] It has also been noted by Muzan himself that Yoriichi's bright red blade was far more effective than those of the modern era Hashira and Tanjiro[22], as Yoriichi could completely negate Muzan's near-absolute regeneration for a short period of time while the Taisho 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.”)

Demon slayer abilities and info

(“Transparent World: Yoriichi had access to the Transparent World since birth, and could use it with incredible proficiency, evident when he could watch for lung expansions and muscle contractions within a person and surmise when to strike them, even as a child.[17] 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,[23] 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 haunted the Demon King for the rest of his life.”)

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.[31] Yoriichi was also able to accurately sense the Demon King's aura, which he describes as magma erupting from a volcano.[32]”)

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.[6] 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.[33] 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.[14]”)

Breathing style

(“Sun Breathing (日ひの呼こ吸きゅう, 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 Kamado who called it Hinokami Kagura (ヒノカミ神楽かぐら, Hinokami Kagura?). Yoriichi was incredibly proficient and unrivalled in his Sun Breathing, being able to take down demons effortlessly and even overwhelm the Demon King and the strongest Upper Rank. When looking through the memories of his ancestor, Tanjiro remarked that when Yoriichi performed the techniques of Sun Breathing, the forms were so strikingly beautiful and breathtaking, he appeared more like a spirit than a man.[34] Even after watching Yoriichi perform Sun Breathing first-hand, it's been noted by Muzan that Tanjiro's techniques were still far inferior to Yoriichi's.[22]”)

Muzan Kibutsuji information

(“Muzan Kibutsuji is the king of demons. He is a male who can shapeshift, however his usual appearance is a man with unnaturally white pale skin, a very youthful and attractive appearance with short curly hair that is black in color and red irises and dilated cat-like pupils. From his mistakes with Yoriichi for underestimating him, Muzan is deathly afraid of Yoriichi, despite Muzan having no other fears than Yoriichi itself. Muzan has been described as a coward for his actions with refusing to stand front to front with Yoriichi nowadays, even mistaking Kokushibo for Yoriichi accidentally sometimes from fear.

Muzan Kibutsuji backstory

(“Muzan Kibutsuji is as born during the Heian Era of ancient Japan to the Bible ubuyashiki family with the curse of being extremely frail and weak. His heart stopped multiple times when he was still a fetus in his mother’s womb and he was declared stillborn upon birth, as he wasn’t breathing and had no pulse. When he was eventually taken away to be cremated, he narrowly escaped death by releasing his first cries. During his childhood, Muzan was constantly sick: as a young man, he was diagnosed with a rare unnamed disease that would kill him before his 20th birthday. When he was still 19 years old, a doctor tried to test him by giving him a special experimental medicine, but when it seemed like it was only making his condition worse, Muzan came to believe that the doctor was a fraud and killed him out of rage by stabbing him in the head. However, not long after he’d taken the medicine, Muzan realized his psychical constitution had improved tremendously and that the doctor’s treatment was indeed working x it also caused him to develop a craving for human flesh and he began consuming humans without hesitation, with his family never s being the first victims. As time passed, Muzan quickly adapted to his new life as a demon and was thrilled with all the incredible abilities that the doctors medicine had given him. However, he would later discover that being cured of his illness had left him with a serious problem; he could no longer walk in the sun without burning to ash.”)

Muzan Kibutsuji backstory

(“While Muzan was glad that he could no longer have to worry about dying from disease, the thought of having to spend the rest of his life abiding the sun wounded his ego and he came to truly regret his foolish decision to kill the doctor before the latter had finished treating him. Upon conducting research on the fingers of the medicine that the doctor had made for him, he discovered that it contained a rare flower called the Blue Spider Lily and believed that it could nullify his weakness to sunlight if he consumed it. To that end, he spent centuries searching for it all over Japan to no avail, as he was unaware that it only bloomed in the daytime for at most 2-4 days a year. Even though he had obtained great power, Muzan considered himself to be imperfect and wanted to somehow get rid of his weakness to sunlight. This desire eventually became an obsession that he would chase for the next 1000 years and, with the search for the Blue Spider Lily going nowhere, he reluctantly decided to use his blood to create more demons under his control, hoping that one of them would be eventually conquer the sun; once this happened, he could take their immunity to sunlight for himself by consuming them and then finally achieve his goal of becoming truly immortal.”)

But.. will that all change because of Yoriichi? Only the time will tell.”)
