Yoriichi Tsugikuni

## Introduction

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 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.[5] 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.

### Character Details

Yoriichi is the strongest Demon Slayer in history, being born with the Demon Slayer Mark, 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

**Stamina**: **Very High** (Could easily outlast any Slayer)

**Intelligence**: **Gifted** (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.)

**Weakness**: **None Notable**

**Breath of the Sun** (*Hi no kokyū*): Created by Yoriichi, the Breath of the Sun is a Breath Style that mimics the sun using the user's movements, techniques and abilities. This Breath Style allows for stronger attacks and makes it feel as if opponents were slashed with fire, drastically slowing down a demon's regenerative healing factor (Demons capable of regenerating limbs at subsonic speeds could barely heal from it). There are 12 known forms created by Yoriichi and later a thirteenth one specifically created to counter Muzan Kibutsuji.

* **Waltz** (*Enbu*) - The user delivers a single high-powered vertical slash.

* **Azure Heaven** (*Heki-ra no Ten*) - The user spins their body horizontally to deliver a 360° slash.

* **Scorching Crimson Mirror** (*Retsujitsu Kōkyō*) - The user unleashes two horizontal slashes to hit or defend from incoming attacks.

* **Bone Burning Sun** (*Shakkotsu En'yō*) - The user unleashes a large circular slash that defends from imminent frontal attacks.

* **The Setting Sun** (*Shayō Tenshin*) - The user backflips into the air to deliver a powerful upended sword slash that aims to decapitate their target.

* **Soaring Flame Haze** (*Hirin Kagerō*) - The user charges towards the target, unleashing a horizontal slash seemingly covered in haze that fails to land, but actually does hit the target.

* **Shining Ray of Grace** (*Kiki Onkō*) - The user spirals into the air and delivers a powerful slash that surrounds the enemy.

* **Sunflower Lance** (*Yōkatotsu*) - The user unleashes a single thrust attack with the point of the blade.

* **Solar Halo Dragon Dance** (*Nichiun no Ryū Kaburimai*) - The user unleashes a continuous fast and powerful sword attack that seemingly takes the form of a Japanese dragon made of solar flames. This technique is capable of decapitating multiple targets at once.

* **Fire Chariot** (*Kasha*) - The user leaps behind the opponent and spins in the air downward, releasing a sword attack in a circular motion.

* **Parhelion Rainbow** (*Gen'nichi Kō*) - The user performs high-speed twists and rotations, thus creating afterimages used mostly to evade attacks. The afterimages work most effectively on enemies with good vision.

* **Flame Waltz** (*Enbu*) - A two-combo strike which starts with a vertical slash and then a horizontal one right after.

* **Thirteenth Form** (*Jū San no kata*) - The user continuously performs all twelve forms of the Breath of the Sun in repetitive succession to increase the accuracy and agility of his movements while reducing fatigue. 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.
