**Yusuke Mizuhara** (水原 雄介, *Mizuhara Yūsuke*?) is a major character in *Kimetsu no Yaiba Reishoki: Sengoku Tales*. He was a Demon Slayer from the Sengoku Period who became the first ever Water Hashira (水柱, *Mizu Bashira*?).

## Etymology

=

* Yūsuke's surname contains the kanji for "water"水 (mizu, ***"water"水***?) and "meadow"原 (hara, ***"meadow"原***?). His first name contains "hero" (雄, *yū*?) and {{Nihongo|"concern oneself with"|介|suk

## Appearance

Yusuke was a young muscular man of tall height who had sharp, yet wide navy blue-colored eyes, and long and wavy black hair tied it behind his head in a slicked back ponytail fashion with a large, neck-length bang arching up to fall on the left side of his face. He also wore a stoic expression on his face.

Yusuke wore a blue, cloud-patterned kimono tucked into his black hakama pants strapped by a white sash around his waist, while also sporting white tabi socks and a pair of zōri with blue straps.

## Personality

Yusuke has shown to be a cool-headed individual who is also confident (a stark contrast to his Taisho Era counterpart, Giyu Tomioka) but snippy as he can be short-tempered, snappish, and rudely brief, while also being both curt and sharp, especially in a condescending way. He is also known to like beautiful things a lot. In most cases, he is on bad terms with Takeshi Hayate, the Wind Hashira, due to them having high tempers that make them clash with each other to see who is better. Despite his personality, Yusuke was protective and caring towards those he is close to and considers his friends, especially towards Yuri Hanae who he knew since their childhood and always cared for her deeply despite not showing it due to what she did to him. However, Yusuke would never let his personal relationships get in the way of his duty, as that would go against his own code. Also unlike his Taisho Era counterpart, Giyu Tomioka, he speaks more and says what is on his mind, even if it hurts people or makes them mad.

It is then revealed by the Flower Hashira, Yuri Hanae, that Yusuke's current personality is as a result of his father and younger sister dying mercilessly at the hands of a demon. Noticing this, he killed it with the tools of forging, even molten metal. After that encounter, he became so distant that all attempts Yuri used were futile until she confronted him directly and revealed that she would bring the old him back. This moved Yusuke that he became the old him, although retaining his snippy attitude and mixing it up with his old personality.

## Abilities

### Overall Abilities

As the creator of Water Breathing and the first Water Hashira of the Demon Slayer Corps, Yusuke was a very powerful and skilled combatant. His strength is said to be equally matched to the Wind Hashira of the time, Takeshi Hayate. Yusuke was also known to easily beat dozens of demons whose strength were equal to the future Lower Ranks of the Twelve Kizuki. Yusuke was also an incredible teammate able to grasp the intentions of his peers and work in tandem with it. Before even becoming a Demon Slayer, Yusuke was able to kill a demon with all sword-forging tools, even pouring hot and molten metal on it to delay its regeneration.

### Physical Abilities

**Immense Speed & Reflexes:** Yusuke possesses inhuman speed and reflexes that are stated to be as smooth as flowing water. It is stated that when fighting demons, Yusuke's joints and limbs displayed unexpected flexibility, allowing him to perform many acrobatic movements in battle.

**Immense Stamina & Endurance:** Due to extremely harsh training, Yusuke has attained incredible stamina and endurance. This allows him to battle longer against demons.

**Indomitable Will:** Yusuke, like most Demon Slayers, possesses an undaunted and indomitable will and spirit.

### Demon Slayer Abilities

**Demon Slayer Mark:** During the Sengoku Period, Yusuke awakens his Demon Slayer Mark due to Yoriichi Tsugikuni's mark resonating with the Demon Slayers of that time, appearing as a blue-colored fluid-water like design on his left cheek, complementing his Breathing Style, Water Breathing. When activated, he gains a tremendous increase in strength, speed, precision, and endurance along with the strength of his Breathing Style by 100x their normal capabilities.

## Fighting Style

**Master Swordsman:** Being a Hashira of the Demon Slayer Corps while also the creator of Water Breathing, Yusuke is one of the most powerful and skilled swordsman in the entire organization, and is acknowledged to possess finely developed swordsmanship.

### Breathing Style

**Water Breathing** (水の呼吸, *Mizu no Kokyū*?): A Breathing Style that he created. As the Water Hashira, Yusuke was his generation's first and most skilled Water Breathing user. Yusuke has completely mastered this swordsmanship style, to the point that he created a total of ten techniques for the Breathing Style.

## Equipment

**Standard Nichirin Katana:** As a Demon Slayer, Yusuke carries around a standard sized and shaped Nichirin katana with a black blade that has a deep blue outline. His katana's handguard is hexagonal shaped with a bronze core and with an overlapping red fuschia border. As a member of the Hashira, Yusuke's katana also had the words **Destroyer of Demons** (惡鬼滅殺, *Akki Messatsu*?) engraved on both sides. With his katana, Yusuke had a standard sword sheath that is deep black in color. Overally, his Nichirin katana bears similarity to Giyu Tomioka's Nichirin katana.

## Trivia

* Yusuke and Mokaro Kuze had only made each other once, at the semi-annual Hashira meeting.
* Yusuke, due to having swordsmithing skills from his father, forged his own Nichirin katana. He also re-forged the Mokaro's rusted Nichirin katana.
* Although Kaito didn't hesitate nor did he show hesitation to killing a demon, he did show leniency when a demon willingly surrenders. He invented the painless 5th form for exactly this occasion. This implies that he doesn't completely despise demons as some other Hashira do, and is willing to make an exception for a demon by mercy-killing them if they don't kill and eat humans. This shows that he is more pragmatic in dealing with demons rather than letting his hatred cloud his judgment.
* After his sister, , and Yuri Hanae, the Flower Hashira, complimented his hair, Yusuke started grooming and regularly applying camellia oil to it, resulting in its silky look. He then began to feel more proud of himself and love himself a little more
* After the deaths of his father and younger sister, Yusuke took the personality we are currently familiar with and made sure that his existence doesn't endanger the people he cares about, including the Flower Hashira who was also his childhood friend, Yuri Hanae.
	+ Because of him distancing himself from her, Yuri resolved to using teasing to lighten his mood. However, after seeing it wouldn't work, she confronted him and talked sense into him, letting him vow to protect her.
* Yusuke served as a Hashira for 31 (1452 to 1483) years.
