Kyojuro Rengoku: Everything you Need to Know About the Demon Slayer

Table of Contents

Demon Slayer by Kiyoharu Gotoge is a shining illustration of how absolute simplicity can capture the hearts of millions. Gotoge’s dedication, love, and passion for Demon Slayer: Kimetsu no Yaiba has reached millions of people all over the world. 

Despite the fact that the Demon Slayer manga ended abruptly, we were left wanting more. The manga had sold more than 150 million copies, including digital versions, as of February 2021, making it the ninth best-selling manga series of all time. 

It was also the most popular manga in 2019 and 2020. The manga and its anime adaptation have received positive reviews. The anime series has won many awards and is widely considered one of the best anime series of the decade. 

Kyoujuro Rengoku’s appearance as the Flame Hashira exuded trust, strength, and warmth. Kyoujuro was tall and athletic, and he exuded confidence with a permanent smile on his face. Rengoku’s long hair was pale yellow with red tips, and he had two shoulder-length bangs and two chin-length bangs, just like a flame.

 Even the tips of his brows resembled flames. He also had a golden Iris and bright red pupils that were glistening with zeal. Every fiber of his being glowed like a flame.

Kyojuro Rengoku’s Captivating Personality Traits

Kyojuro Rengoku

Kyojuro was ambitious about his responsibilities as a Hashira and was frequently delightfully quirky. He was also personable and generous, and he wore a happy look virtually all of the time. He was affable, kind, and possessed exceptional technique and swordsmanship as a result of rigorous training and discipline.

ESFJ-A, Kyojuro’s personality code, stands for Extraverted Observant Feeling Judging Assertive, indicating an active personality with some constraint and purpose. Such people are usually outgoing and considerate of others, and they can even be the life of the party.  Even if they don’t seek a large circle of friends, Consuls like Kyojuro Rengoku are concerned about the well-being of others, and they operate nearly solely on behalf of those around them. Consuls, with their disciplined, caring, and positive attitudes, are role models who may inspire anybody and those around them.

During the Mugen Train story arc, Kyojuro is to Tanjiro’s crew what he was to his brother during the main events of Demon Slayer and behaves as a protective big brother to them. Kyojuro, as a true Consul, will blindly obey his superior officers’ commands and sacrifice his life in the process, and he even opposed other characters for hiding the demon Nezuko from other slayers. Laws and traditions are crucial to a Consul like Kyojuro, and they should not be broken lightly. However, Kyojuro eventually welcomes Nezuko and no longer objects to her presence.

kyojuro and tanjiro

Kyojuro reveals his ESFJ-ness during the Mugen Train tale arc. Once again, a personality was zealously carrying out his mission against terrible demons and inspiring Tanjiro, Inosuke, and Zenitsu through his excellent example. Rengoku puts his life at risk to protect them, and when he dies following a confrontation with the demon Akaza, he makes sure that his final words are inspiring and motivational, bestowing one final gift to his cherished friends and allies. Furthermore, Kyojuro, as a true Consul, refuses to break the demon slayer law and accepts Akaza’s invitation to become a demon himself, even if it would give him strength and save his life.

If a Consul can’t do something well, they won’t do it at all, and Tanjiro will need that type of discipline and sense of responsibility as he moves forward in the Entertainment District story arc. In his childhood, he was just like any other youngster. Rengoku, on the other hand, was unprepared for the hardship of losing his mother as a child and witnessing his father wallow in grief. Kyoujuro Rengoku never mistreated his father after his mother’s death, even though he was always rejected by him. His mother’s parting remarks, on the other hand, have inspired him to proudly stand as a Hashira who protects the helpless.

“Helping the weak is the duty of those born with strength. You must take your responsibility seriously and do your duty and never ever forget that.” Ruka Rengoku. And it is in these words that the Flame Hashira, Kyoujuro Rengoku, is built. In his father’s absence, he not only rose to the level of Flame Hashira, but he also stood by his younger brother during difficult times by being truthful and honest with him. Unfortunately, we only got to see Rengoku’s beautiful and heartfelt grin as he took his final breath.

Kyojuro Rengoku’s Extraordinary Powers

Kyojuro is a skilled swordsman and a Hashira of the Demon Slayer Corps. Even Demons as powerful as Akaza, Upper Rank 3 and the fourth-strongest Demon in the world, recognized Kyojuro’s power. He even offered to convert Kyojuro into a Demon so he might surpass his human boundaries and become even stronger, something he only did for swordsmen whose powers he considered were at their pinnacle.

kyojuro rengoku power

Akaza also praised his battle spirit, saying that it was approaching the “domain of supremacy,” implying that he was on his way to acquiring the translucent world, which is only available to the strongest Demon Slayers. Shinjuro Rengoku, Kyojuro’s father, claimed that after his son abandoned what he taught him, Kyojuro trained himself to the level of a Hashira by reading through a three-volume Flame Breathing instruction book.

Breathing Flames

Rengoku was able to boost the amount of oxygen in his blood by manipulating his breathing rhythm, allowing him to match the strength and agility of a demon. Kyojuro had learned to take full-focus breaths at all times, boosting his foundation strength, speed, and stamina even more.

He was able to prevent bleeding from injuries by concentrating his breathing on certain points. The Breath of Flames can be implemented in at least nine different methods. However, Rengoku only demonstrated five of them. Kyojuro’s first form is Unknowing Fire, in which he charges at his opponent at a fast speed and decapitates them with one or more slashes that burn his opponent’s skin. 

This approach was sufficient to propel the entire Infinity Train a short distance off the tracks. His second form was  Rising Scorching Sun – Kyojuro attacks upwards with an arching slash. Kyojuro slices his blade downwards in an arc in his third form, Blazing Universe. Fourth Form: Blooming Flame Undulation – Kyojuro spins his blade in a circular motion, diverting the assaults of his rivals.

The fifth form, Flame Tiger, was a series of sword slashes that took on the shape of a tiger. Kyojuro used this technique to fight Akaza’s Destructive Death. Rengoku, Kyojuro’s Ninth Form, is a powerful slash that he launches from a high stance, with enough force to carve a deep impression in the earth where he used it. He observed to himself before adopting this technique that he had “thoroughly hollowed out most of the region.”

Natural Abilities of Kyojuro

Master Swordsman: As a Hashira of the Demon Slayer Corps, Kyojuro is one of the organization’s most powerful and skilled swordsmen. His skill of the blade is most demonstrated during his combat with Akaza, as he holds his own against the Upper Rank while being severely hurt.

Enhanced Strength: Despite being severely injured at the time, Kyojuro exhibited incredible hand and arm strength, which Akaza described as “unbelievable.” Kyojuro’s enhanced speed allowed him to move at speeds that even an experienced Demon Hunter like Tanjiro couldn’t see or follow, causing tremors in the process. 

kyojuro natural abilities

In fighting, Kyojuro has exhibited remarkable resilience and stamina. When Kyojuro merged into the entire train during the fight with Enmu, he was able to stop him and, more crucially, fight back in five cars of the train without being exhausted. Despite being physically and emotionally strained and enduring multiple minor and deadly injuries such as a broken eye, fractured ribs, and internal organ damage, he was able to stay up with his most difficult rival, Akaza. 

Despite the fact that the most crucial areas of his body, the solar plexus, were punctured by the force of the moon’s height, he was able to keep Akaza down with only his hands. He never hesitated or exhibited any signs of anguish or pain, despite his critical injuries and wounds.

Insight’s of the Battles Fought by Kyojuro Rengoku

Kyojuri Rengoku Vs. Hairo

A chunk of dynamite is displayed inside a nearby chapel and detonates, causing a massive explosion. Kyojuro, Mitsuri, and the other Demon Slayers are profoundly perplexed by this. Mitsuri exclaims that she wants to help Kyojuro and races toward the explosion site to assist any nearby civilians.

A bullet from the top of a nearby building nearly scrapes her face off before she gets too far. When Kyojuro examines the bullet’s trajectory and where it landed, he notices the source: a sniper on the very top of a skyscraper.

hairo demon slayer

The Kinoe-ranked Slayer appeared in front of him and attempted to behead him with Flame Breathing, First Form: Unknowing Fire, but he dodged the attack, his right arm holding his sniper rifle being severed. The man regains his composure by stating that all he has done thus far has been in preparation for this day. He says Kyojuro’s surname again, emphasizing that everything is for now. The characters for Lower and Two appear on Kyojuro’s left iris, indicating that the man is a member of the Twelve Kizuki.

To restore his calm, the Demon shoots himself in the mouth. As the Lower Rank says that he has set up explosives behind Tky, a big explosion occurs behind the Demon Slayer. Suddenly, a hail of bullets rains down on the Demon Slayer, who manages to deflect them all. The Lower Rank emerges with Springfields, Mauser C96s, and a Webley Revolver in his right hand and fires a barrage of bullets at Kyojuro, who manages to avoid them. Kyojuro comes and uses Flame Breathing, Fifth Form: Flame Tiger, to halt the Lower Rank from approaching Mitsuri, cutting his neck and knocking him back. Kyojuro declares himself to be a Demon Slayer and that he will carry out his responsibilities.

Kyojuri Rengoku Vs. Emmu

Kyojuri Rengoku Vs. Emmu

Following the events at Mount Natagumo, Kyojuro makes his first appearance at the Pillar Assembly, which decides the fate of Tanjiro and Nezuko Kamado, as well as Guyu Tomioki. Rengoku spoke out against Kagai Ubayashiki’s idea at the meeting, urging that Tanjiro Kamado be brought to justice.

The heroes and the Pillar, on the other hand, met on a quest to track down a demon who was attacking passengers on the Infinity Train. Tanjiro managed to question Kyojuro about the Fire God’s Breath before the demon attacked. Pillar admitted that it was the first time he’d heard of it, and he advised him to become Tanjiro’s apprentice, as well as guaranteeing his safety.

The spell of Enmu has absorbed Kyojuro and the other passengers on the train. While being impacted by the method, Kyoujuro’s “soul essence” was invaded by a lady controlled by Enmu, who attempted to destroy this “soul kernel.” He was able to defend himself and ward off his attackers in the material world since the girl attacked him while he was sleeping, but he was unable to vanquish the girl because there was no motivation for him to murder her.

Kyojuri Rengoku Vs. Emmu

Kyojuro launched a series of violent attacks on the demon in order to break free from the demon’s methods. He also put together a team of demon assassins to safeguard the bulk of the passengers on the train at the same time. Kyojuro deployed a range of powerful methods to reduce the impact on the train’s passengers as it slipped off the tracks. He assisted Tanjiro in stopping the bleeding after defeating Enmu. During the battle, he certified that no one was killed. Being the first moon below the horizon, The Third High Moon 3 appeared in less than a second.

Kyojuri Rengoku Vs. Akaza

Akaza swoops down on the injured demon hunter, aiming to murder Tanjiro (as was his goal), but Kyojuro fends him off in the nick of time. As the battle progressed, Akaza, realizing Kyojuro’s strength, offered Kyojuro to join the Twelve Demon Moons, but the Flame Pillar declined. Before or during their battle, they both began explaining their respective views on life.

Kyojuri Rengoku Vs. Akaza

Akaza is shown to hate humans for being weak, while Rengoku began telling him that humanity has more to its beauty than just strength alone. In addition to being told to stay on standby by Kyojuro, Tanjiro, Zenitsu, and Inosuke could only observe their struggle because they understood they could become an obstacle to Kyojuro. Rengoku was becoming more determined to rise up and perform his obligations of defending those around him, despite Akaza’s great might. However, as powerful as Kyojuro was, he was only a man, whereas Akaza was a demon; as the struggle progressed, Kyojuro became increasingly exhausted and got more wounds, each one more severe than the last, while Akaza healed all of Kyojuro’s wounds.

Even though Akaza tries to persuade Rengoku to become a demon when his body is too damaged to continue fighting, Rengoku refuses as he prepares to fully release the ultimate Flame Breathing technique, just as Akaza prepares to fully unleash his own strong Blood Demon Art technique. Tanjiro, enraged, used his ability to slash the demon with his sword. 

Tanjiro called Akazu an oaf for fleeing, and Kyojuro was pronounced the winner of the bout. However, Akaza emerges victorious by impaling Kyojuro’s stomach, causing a massive wound that causes him to lose a large quantity of blood, therefore sealing Kyojuro’s doom. Kyojuro was on his deathbed. Tanjiro was asked by Kyojuro not to scream too loudly for fear of opening his wound. 

Kyojuri Rengoku Vs. Akaza

When he died, Kyojuro told Tanjiro that he could recognize his demon sister Nezuko as the Demon Killer, and he gave Tanjiro his final instructions, telling him to go to Rengoku Manor and discover answers to the questions about the Fire God’s breath. Kyoujuro was able to glimpse the outline of his mother in the closing moments of his life and questioned if he had met his mother’s wishes. His late mother gave him a positive response.

Meet the Friends & Family of Kyojuro Rengoku

Kyojuro admired his father, Shunjuro, once the Flame Pillar, when he was a boy. Shunjuro was a revered parent while he was the Flame Pillar. After being crushed by his own inadequacy and the death of his wife, Ruka, he abandoned his swordsman position and became a drunk every day. Shunjuro began to mistreat his two sons after that.

Kyojuro Rengoku family

Shunjuro reacted angrily when Tanjiro informed him about Kyojuro’s last will and testament. And said, “He didn’t have much talent to be a swordsman, and that’s why he’s dead! Nonsense, Kyojuro is a stupid son!” Shunjuro also has a large complex regarding the Sun’s Breathing (Hinokami kagura). Shunjuro attempted to defeat Tanjiro after learning of Tanjiro’s ability to employ Breathing of the Sun. Senjiro, his son, attempted to halt the conflict, but Shunjuro retaliated by assaulting his son. Shunjuro’s personality has been distorted to the point that it’s difficult to believe he’s the former pillar (Hashira).

Ruka, Kyojuro’s mother, was a strong and caring woman. She instructed Kyojuro when he was a child that he should aid the weak. Kyojuro was defined by her teachings. Ruka died when Senjiro, Kyojuro’s younger brother, was a child. Ruka emerged just before Kyojuro’s death. Ruka grinned and nodded to Kyojuro, who then inquired about Ruka’s ability to complete his objective. Senjiro, his younger brother, unlike Kyojuro, is a meek kid who can’t say anything to his inebriated, verbally abusive father. Senjiro is a poor swordsman, as evidenced by the fact that the hue of his Nichirin Blade has remained unchanged.

He blames himself for the Flame Breather’s successor’s death. Tanjiro gave Senjiro a remembrance of Kyojuro, the crimson nichirin sword. Senjiro and Tanjiro became friends after that and began writing to one other. During their initial encounter at Ubuyashiki Manor, Kyojuro was enraged by Tanjiro because he disobeyed an unwritten code that was part of the Demon Slayer Corps; he was a guardian of his demon sister, which is why he insists on bringing down Nezuko Kamado and punishing Tanjiro. After a second meeting with Tanjiro at the Infinity Train, he begins to feel compassion for him as the story progresses. 

kyojuro and tanjiro

As members of Kyojuro’s Demon Slayer Corps, the two hunters form an intimate bond with their fellow hunters, to the point where Kyojuro is eager to make Tanjiro his Tsuguko. Tanjiro is able to gain Kyojuro’s respect and devotion to the point where Kyojuro refers to him as “Aniki” (elder brother), demonstrating their close friendship. Tanjiro is awestruck by Kyojuro’s sword abilities and his ability to laugh in the face of adversity. Just before his death, Kyojuro confides in Tanjiro about his dying wishes. Senjuro, Kyojuro’s younger brother, will hand over his tsuba to Tanjiro in the coming days.

Inosuke did not like Kyojuro when he first met him, like most of the individuals he met. However, after witnessing Kyojuro defend those on train travels and fight Akaza, He began to respect Kyojuro’s sword manship, power, and mastery. Inosuke lifted Tanjiro’s spirits when Kyojuro died, reminding him of the things Kyojuro spoke to them before he died, as well as the fact that Kyojuro believed in his pillar. Initially, Kyojuro disliked Nezuko, whom he saw as a menace to humanity, and he advocated for her death and Tanjiro’s execution, claiming that he had broken his Demon Slayer Corps’ cardinal tenet of not protecting demons.

Kyoujuro told Tanjiro in the Infinity Train before falling asleep in the sleep method that he had nothing against Nezuko because Kagaya Ubuyashiki had accepted her. Following the combat on the Endless Train, Kyojuro expressed his gratitude to Nezuko for defending the train’s passengers. While Kyojuro was dying, he informed Tanjiro that he was a believer in Nezuko and that he saw her as a Demon Killer Corps member. Obanai was believed to have a deep admiration for Kyojuro and to adore his personality. Shinjuro, Kyojuro’s father, was tied to Kyojuro’s Rengoku lineage since he was able to save his son Obanai from a serpent demon when he was a child. He thought Kyojuro was a great swordsman and was surprised when he died.

kyojuro and friends

Tengen was always a fan of Kyojuro in Demon Slayer, and when they first met, he was one of the few of Kyojuro’s pillars who didn’t show enmity toward Kyojuro, who was about to become the next pillar of the flame. Tengen had always thought Kyojuro was a charming character, and he liked the color of Kyojuro’s family’s Rengoku haircut. During his battle with Gyutaro, he began to consider the other members of his gang and chose Kyojuro as his model. After Kyojuro’s death, he was shaken. Kyojuro Shinobu was kind, and it was clear that Shinobu looked after Shinobu and wished him good success before sending Kyojuro off on his mission. Despite Kocho’s first handicap of being unable to chop demon heads, he was impressed by her passion for her work and was eager to battle. The loss of Kyojuro devastated Shinobu.

Kyujuro Rengoku’s Non-Existing Love Interest

If given the opportunity, Flame Hashira Kyojuro Rengoku would like to have his own wife. In the original Demon Slayer, he never had the chance to pursue romance, but if he wanted, he could choose a great partner and wife from among the myriad characters in anime. 

kyojuro rengoku and mitsuri

Although, it is believed by the fans that Mitsuri Kanroji was his love interest of Rengoku. Mitsuri’s mentor, Kyojuro, was a close friend of Mitsuri’s, and Mitsuri thought of him as an elder brother. Kyojuro was severe with her training while she was under his tutelage, but he was also patient and doted on her at times. They both have a gluttonous side and like to munch during their breaks. Mitsuri took his Flame Breathing and created her own unique Breathing Style, Love Breathing. Kyojuro has a special place in her heart for his guidance and kindness. Mitsuri was stunned and heartbroken when she learned of his death.

Behind the Voice of Rengoku’s Character

Demon Slayer: Kimetsu no Yaibe the Movie: Mugen Train’s massive box office success is an unquestionable achievement for anime and foreign-language films as a medium. The Demon Slayer film is notable for its location in the series’ chronology—it essentially covers the story arc that connects the first and next seasons.

While Tanjiro Kamado is the main character, Mugen Train focuses a lot on Kyojuro Rengoku, a powerful leader in the Demon Slayer Corps known as the Flame Hashira. Fans of Rengoku may find new methods to set their hearts on fire after watching the blockbuster film and now waiting for the highly anticipated second season by watching other anime in which Rengoku’s voice actor, Satoshi Hino, has offered his talents.

Interesting Fan Theories Based on Kyojuro Rengoku

kyojuro rengoku loud voice

According to one popular notion, Kyojuro’s loudness stems from his first Demon Slayer mission. Kyojuro’s loud voice complemented his confident command of any room he entered, so it could have just been a character feature outside of his combat with the Flute Demon. Rengoku.

As the Flame Hashira and a master of his own breathing technique, set an example for newer Demon Slayers like Tanjiro, a responsibility Kyojuro took seriously. He never stopped smiling and inspiring people, even when the odds were stacked against him. This unshakeable assurance complemented his exuberant demeanor. Rengoku’s death is one of the most highly debated hypotheses among enthusiasts. Was the death of Hashira’s prime worth it in the movie? Why did Hashira, the audience’s favorite, die in the final act? This is one of the most frequently asked questions by filmmakers.

What caused Tanjiro to lose him? That question can be answered in a variety of ways. From the standpoint of the plot, the simplest response is that Peter would never have become Spider-Man if he hadn’t lost Uncle Ben. The death of Tanjiro’s family fueled his determination to track down Muzan Kibutsuji. Rengoku, on the other hand, would never have realized the gravity of the battle he was about to engage in if he hadn’t died.

(Spoiler Alert!!!) What Happened After Rengoku’s Death?

kyojuro spoiler

The news that Kyojuro had died in the line of duty shocked and saddened the Demon Slayer Corps. Kanao was taken aback, and Tengen lamented the fact that even someone as powerful as Kyojuro couldn’t defeat an Upper Moon monster. Obanai hesitated to believe the obvious until he saw it with his own eyes, and Mitsuri was appalled.

Sanemi prepared himself to exorcize demons as Gyomei prayed for Kyojuro’s soul. Kagaya Ubuyashiki commended Kyojuro for his bravery and sacrifice but warned that he, too, was running out of time and would soon join the departed Flame Pillar in the afterlife. While mourning, Tanjiro was dissatisfied that he had overcome one challenge to become stronger, only to be confronted with an even bigger and more difficult obstacle.

Inosuke chastises Tanjiro and Zenitsu for not grieving Kyojuro’s death, claiming that he had only returned to earth and that all they can do now is keep living and surviving in order to keep the vow they made with Kyojuro. Inosuke was mourning just as much as Tanjiro, as Zenitsu pointed out.

However, as the series progresses, Tanjiro remembers Rengoku with gratitude for his support and letters left for him, which he promises would assist him in finally putting an end to Muzan’s development of the Demon race for the greater good. And when Muzan Kibutsuji turned Tanjiro into a demon, Kyojuro’s spirit was one of the departed who assisted in rescuing Tanjiro’s humanity.

The Final Thoughts on Kyojuro Rengoku’s Character

Don’t we all desire Rengoku to have more screen time? But it’s also true that the impact he made on myself and the other readers with his little but significant appearance in the novel wouldn’t be as strong as it is now. 

That’s how well-written our favorite Flame Hashira’s character, Kyojuro Rengoku, is. Who’d have guessed that a single 22-page chapter would turn out to be one of the strongest character-driven chapters in the Demon Slayer: Kimetsu no Yaiba manga. Who knew the Infinity wasn’t truly endless but rather had a limit? One that is tragic. It’s difficult to recover from the defeat, but keep in mind that he was triumphant until the very end.
