Yoriichi Tsugikuni

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

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

Fighting Style (continuation of the above section)

Eleven form: Fake Rainbow (幻げん日にち虹こう, Gen'nichi Kō?)[46] - The user performs high-speed twists and rotations, thus creating afterimages used mostly to evade attacks. The afterimages work most effectively on enemies with sharp vision.[46] -Twelfth form: Flame Dance (炎えん舞ぶ, Enbu?)[47] - A two-combo strike which starts with a vertical slash leading into a horizontal slash right after. -Thirteenth Form (拾じゅう参さんノ型かた, Jū San no kata?)[48] - The user continuously performs all twelve forms of Sun Breathing in repetitive succession to increase the accuracy and agility of their 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.

Abilities

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[6] 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.[7] 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.[8] Despite having avoided death, Muzan was deeply scarred by that encounter, referring to him as the true "monster" between the two of them,[9] and even the sight of his earrings made him tremble in shock[10], while mere memories of Yoriichi caused the bodies of other demons who have never met him to tremble.[11] 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.[15] He also displayed maturity beyond his age as he noticed her mother's illness and helped her all the way till her death.[16] 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.[17]

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 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]

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.[24] Even when Muzan divided himself into 1,800 flesh pieces to escape, Yoriichi still managed to reduce the number down to 300 in mere moments.[25] Even on the last day of his life, he was able to easily blitz Kokushibo, Muzan's strongest subordinate, nearly severing his neck instantly, despite Yoriichi telling him when he will strike.[26] 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 six arms because two arms alone couldn't replicate Yoriichi's movements.[27]
