Enjūro Rengoku

### Flame Hashira:

**Enjūro Rengoku** (煉獄 炎柔郎 *Rengoku Enjūrō*) was the brother of yoriichi. He was a Demon Slayer of the Demon Slayer Corps and the first Flame Hashira (炎柱 *En Bashira*).

## Appearance

Enjūro was a young adult of tall stature and muscular-athletic build. He was known to be charismatic and has an air of great optimism, having an enthusiastic smile plastered on his face nearly all the time. He had long bright yellow hair with red streaks akin to flames along with two chin-length bangs on the side of his head, black forked eyebrows, and golden eyes that fade to red with white pupils.

Enjūro wore a paler brown version of the regular Demon Slayer uniform of the Sengoku Era, which consisted of a brown kimono jacket, a white cloth around his waist and tattsuke-hakama pants. Over this, he wore another kimono jacket that fades from red to bright orange the more it went down. Finally, he wore red kyahan with yellow flames erupting from the bottom-up, with pale brown tabi socks and a pair of white zōri with red straps.

## Personality

Enjūro was greatly enthusiastic regarding his duties as a Hashira and often came across as cheerfully eccentric. He was amiable, pure of heart, and boasted extraordinary technique and swordsmanship stemming from strict practice and discipline. He was an honorable warrior who adhered to his code of morals and principles that was instilled into him by his father at a young age—the most significant being his belief that those who were born strong must protect the weak. He could be childish and naive at times though.

Enjūro also loved his family immensely, displaying great respect and worry towards his father, Enji Rengoku. He is incredibly encouraging and optimistic towards his little brother, Kenjuro Rengoku, believing in him and wishing him the best no matter what. This is further accentuated during his death where his final words for his little brother were "take care of yourself" and "follow your dreams no matter what". Enjūro also believed that if someone lacks immense skill, his/her hard work towards their dreams and desire to help people doesn't count for nothing.

Beneath his enthusiastic demeanor, Enjūro was very logical and tactically intelligent, acting quickly and precisely in battle, especially when the lives of others were on the line. Enjūro was also great in seeing talent in others, even in Kaito, a half-demon which he wanted to kill beforehand, after seeing him risk his life to fight and protect others. Though he was extremely optimistic, Enjūro did sometimes have a sense of foreboding that those he believes in might die, especially his friends which he care deeply for. Lastly, he, like most Demon Slayers, absolutely detested demons, usually because of their heinous deeds or because of their clashing morale values. Despite this, however, Enjūro recognized and accepted Kaito as a member of the Demon Slayer Corps after seeing him risk his life to protect innocents, showing that Enjūro is capable of not letting his hatred for demons cloud his judgement.

## Abilities

**Overall Abilities:** As a Hashira of the Demon Slayer Corps, Enjūro was a very powerful and skilled combatant. Before he took his father's place, Enjūro was already shown to be an amazing fighter. He managed to successfully pass his final selection and slay dozens of demons in a period with no breathing techniques by himself and later managed to singlehandedly chase off and defeat a demon who attacked Water Hashira Yūsuke Mizuhara's former home.

As another testament to his strength, even demons as strong as Kokushibo and the second-strongest of the known demons of the Sengoku Era, acknowledged and praised Enjūro's strength. He even went as far as to offer to turn him into a demon so he could surpass his human limits and become stronger, something he only offered to swordsmen whose abilities he believed were refined to their utmost. Kokushibo also complimented his fighting spirit and stated that it is getting close to the "Realm of the Highest," which implied that he had already obtained the Transparent World (透き通る世界 *Sukitōru Sekai*) and was incredibly close to obtaining the Selfless State (無我の境地 *Muga no Kyōchi*).

**Extrasensory Perception:** Enjūro had incredibly honed senses, such as when he was able to sense and perceive Kokushibo's immense presence and demon aura which he uses to discern that he was an extremely powerful demon. Enjūro was also capable of sensing demonic presences faster and more accurately than Tatsuya Kamado, who harbors an acute sense of smell. This ability also allowed him to precisely gauge the regenerative abilities and weaknesses of most demons. Enjūro was also able to perceive Tatsuya's injuries and torn blood vessel accurately, which allowed him to teach him how to plug up that wound and prevent him from dying of blood loss. Furthermore, he was able to detect malice in many blood demon arts and prevented himself from getting incapacitated through detecting its malice.

**Immense Speed & Reflexes:** As a Hashira, Enjūro possessed tremendous speed and reflexes that even a trained and gifted Demon Slayer like Tatsuya could not perceive or register. Enjūro could even cause tremors to the ground by running at such high speeds. Moreover, Enjūro could easily move at speeds much faster than the eye can see, decapitating demons before they can even react. His reflexes were so fast that he managed to break Kokushibo's flesh sword moments before the Upper Rank was going to skewer Tatsuya. Enjūro also managed to keep up with Kokushibo's high-speed techniques and incredibly swift movements, which he remarks is faster than the blink of an eye, sometimes even managing to out-speed him. This surprised and even impressed Kokushibo himself, who openly expressed his amazement over. As another testament to Kyojuro's immense movement speed, Kaito remarked that he was so fast that it seemed like he was in a completely different dimension.

**Immense Stamina & Endurance:** Enjūro displayed superhuman stamina and endurance during his battles over the course of his career. During his final selection, Enjūro suffered many injuries, yet didn't flinch in the slightest, ignored the pain and continued to fight and win. In the time when Yoriichi Tsugikuni taught his breathing techniques to other demon slayers, he was able to keep on training and mastering his style where most other demon slayers were already exhausted.

Lastly, he managed to keep up with Kokushibo, one of the strongest demons in existence despite physically and mentally exert himself beyond his limit and sustaining multiple irreparable and fatal wounds, like deep cuts all over his body, shattered ribs and damaged internal organs. Most impressively, he managed to keep Kokushibo at bay despite having his vital spot, his Solar Plexus, pierced by the Upper Rank's sword and bleeding out. Despite all of his fatal wounds and injuries, he never once flinched or showed signs of pain or agony.

**Immense Strength:** As a Hashira who spent years perfecting his physical prowess, Enjūro possessed amazing physical strength, being capable of swinging his katana at speeds faster than the eye can see incessantly with terrifying accuracy while engaging in combat and even send Kokushibo flying an astonishing distance with a single blade swing. Enjūro could also launch giant swathes of dirt and earth off the ground by simply dashing forward. Enjūro also possessed exceptional grip strength that enabled him to hold down Kokushibo, one of the physically strongest demons in existence, despite having his solar plexus pierced earlier and sustaining multiple other fatal wounds, to the point which Kokushibo expressed his disbelief and shock over Enjūro's strength which he describes as "unearthly".

**Indomitable Will:** Enjūro had an undaunted spirit and indomitable willpower, which even impressed the likes of Kokushibo. Ever since he was a child, he had inculcated indomitable will and passion in himself due to his promise to his late mother. Even when Kokushibo overwhelmed him with powerful attacks, giving Enjūro insidious wounds, he remained steadfast and resolute. After Enjūro lost an eye and had internal wounds caused by Kokushibo's stabs and cuts, he still persisted, vehemently expressing his unwavering will and determination, saying that he will protect the lives of the other innocent people no matter what. Finally, when Kokushibo's sword pierced his solar plexus, it triggered a memory reminding Kyojuro of his mother again, giving him the final push to cut the his neck. In the end, though his efforts were in vain, his incredible determination had a profound effect on Tatsuya, giving the incentive to push on no matter the turmoil he faced.

**Keen Intellect:** As a swordsman standing at the start of a long lineage of Flame Hashira, Enjūro was basically a trendsetter. He did not have access to generations of combat knowledge and tactics, only training from his father, Enji Rengoku. Enjūro also created and mastered the entire Flame Breathing style just by being taught a breathing technique that suited him by Yoriichi Tsugikuni. During the battle against Kokushibo, he displayed keen judgement like after being attacked by Kokushibo's **Moon Breathing**. He realized that he must fight at close range if he wanted to increase the chances of cutting off his head. Even when the usually deductive and sagacious Tatsuya Kamado was at a loss of how to destroy demonic illusions, Enjūro instinctively knew that, no matter what form a demon takes, it will always have a weak spot. He also possessed great knowledge in the use of the **Total Concentration Breathing** (全集中の呼吸 *Zen Shūchū no Kokyū*), knowing how to plug minor wounds and hemorrhaging and saved Tatsuya from dying of blood loss.

**Demon Slayer Mark:** During his battle against Gaarashi, Enjūro awakened his Demon Slayer Mark, appearing as a flame like design on his right forehead, complementing his Breathing Style, Flame Breathing. When activated, he gains a tremendous increase in speed, precision, and endurance to the point where he could engage in a long battle against an Archdemon.

* **Bright Red Nichirin Sword:** After Enjūro had unlocked his Demon Slayer Mark, he obtained the ability to temporarily dye his sword bright red, which granted him the ability to hamper the enhanced regeneration of any demon.
* **Transparent World:** After Enjūro had unlocked his Demon Slayer Mark, he obtained the ability to temporarily access the transparent world.

## Fighting Style

**Master Swordsman:** As he was a Hashira of the Demon Slayer Corps, Enjūro was one of the most powerful and skilled swordsmen in the entire organization. Additionally, Enjūro is part of the first generation of Hashira which has an impressive line-up of fellow powerful swordsmen that were personally trained and taught by the legendary Yoriichi Tsugikuni himself, giving Enjūro an edge in developing and polishing his swordsmanship to perfection. His extraordinary swordsmanship skill has been displayed during many battles throughout his career. His mastery of the blade is best showcased during his battle with Gaarashi, in which he was more than capable of fighting on equal ground with the Archdemon who has killed countless Demon Slayers over the last century, even to the point that Gaarashi constantly praised Enjūro's swordsmanship despite the fact that he hated swords.

### Breathing Style

**Flame Breathing** (炎の呼吸 *Honō no kokyū*): A Breathing Style taught to Enjūro by Yoriichi Tsugikuni. He later mastered it and created all nine forms of flame breathing. As the Flame Hashira, Enjūro is his generation's most skilled Flame Breathing user. He became evidently proficient in fighting with this Breathing Style, being able to later hold his own against Archdemon Three, Gaarashi, and Kokushibo.

## Equipment

**Standard Nichirin Katana:** Enjūro carried a standard sized and shaped katana made from scarlet ore that is a deep shade of reddish-orange in color with the words **Destroyer of Demons** (惡鬼滅殺 *Akki Messatsu*) engraved on the side. There is also a noticeable flame pattern on each side of his katana with a white handle. Enjūro's sword tsuba is shaped like a flame with a red core and orange border. He also carried a standard sword sheath that was white and grey in color.

## Trivia:

* Enjūro's surname means "purgatory" (煉獄 *rengoku*). His first name contains the kanji for "flame" (炎 *en*), "gentleness" (柔 *jū*), and "son" (郎 *rō*).
* Enjūro loved to write, especially records of the Corps.
* Enjūro once rescued a dog from a bear. However, he had too little time to take care of the dog, so his younger brother and housekeeper took care of him instead.
* Enjūro created the ninth form of Flame Breathing during his final battle, calling it 'The essence of Flame Breathing.'
* Enjūro's Rengoku-Decree included a practice called "Kankagari" (觀篝). For the duration of their pregnancies/gestation period, every seven days the wives will spend two hours gazing at a large flaming torch. This seems to be what causes the men in the family to have flame-colored hair.
* Many of his peers are unable to keep up with Enjūro since he is "too fast" (He would reach conclusions quickly, he's quick to change his mind, he would eat quickly, etc.). Despite this, he was sensitive to other people's emotions and was caring, making most of the corps members like him.
* Enjūro might have been more powerful than Kyojuro since he created and knew Flame Breathing the best.
