Oldest Demon Slayer Characters

Muzan Kibutsuji
Muzan Kibutsuji

With Demon Slayer entertainment district arc having ended. The anime was so good such that it generated more popularity for the already ended manga as well. The anime producers did not waste any time, and right after that, they announced the adaptation of the wordsmith village arc. It will be the third season of demon slayer and will see the aftermath of the destruction of the entertainment district and what will follow for Tanjiro and his team. The entertainment district was so harsh on the young demon slayers even though they had a strong hashira guiding them.

The anime opened with interesting scenes from the Demon Slayer Infinite Train arc. But things were on the low when Rengoku was killed despite how things went at the time. Then this was a wake-up call for Tanjiro and his team for the upcoming entertainment district arc action. We are used to the fact that the protagonists always win. And recently, the anime is putting this to the test with things getting more and more difficult, even for the Hashiras. So when Rengoku was defeated, we all thought that the sound hashira would be way stronger and would settle things easier.

Right now, Demon Slayer Kimetsu no Yaiba is only left with four more arcs until the anime completely comes to an end. Next will be Demon Slayer Kimetsu no Yaiba sword smith village arc that will explore the character development and how the entertainment district arc has affected Tanjiro and his team. Looking at the oldest demons slayer Kimetsu no Yaiba characters. Things are as strange as they can be as we know that demons can live way longer than humans. The oldest demon slayer characters from the manga and anime are as follows.

Kyojuro Rengoku: 20 Years

How old is Kyojuro Rengoku from Demon Slayer Kimetsu no Yaiba? The infinity train arc revealed the fire hashira and his strengths. But all that was brought down to naught when Akaza appeared and toyed with the demon slayers with little to no effort.

Oldest Demon Slayer

Kyojuro Rengoku


Rengoku was the fire Hashira before succumbing to several wounds when he fought Akaza after the defeat of the infinite train demon. This came as a showcase of how strong the upper demons are and what will be coming in the seasons to follow. So we managed to see the fall of even Rengoku, who is a very powerful Hashira himself. So it is still clear that to the demons, humans are still inferior.

Giyu Tomioka: 21 Years Old

With his familiar catchphrase being, “Don’t cry, don’t despair, now is not the time for that. Feel the rage; the powerful, pure rage of not being able to forgive will become your unswerving drive to take action.” Giyu is one of the Hashiras in Demon Slayer Kimetsu no Yaiba. And if you were looking for the best demon slayer quotes, then you might as look through some of his sayings.

Oldest Demon Slayer


In the anime and manga, Giyu appears like a tall young man with muscular stature and is pale in complexion. He always has a serious and emotionless expression. By the time the manga ended, Giyu was only 21 years and had not lived that long compared to how demons and other Hashira have managed to fare.

Obanai Iguro 21 Years Old

Another character joining the 21 years old group is Obanai Iguro. Looking at demon slayer Kimetsu no Yaiba character’s age, Iguro is still considered amongst the upcoming Hashira, considering his age. Despite all that, his skills have proven to be exceptional as he ranks amongst the most powerful demon slayer characters. Iguro is the serpent hashira and is one of the very strict characters in the series.

Oldest Demon Slayer


He played a pivotal role in the manga when he awakened his demon slayer mark during the final battle against Muzan. At such a young age, he has proven to be a powerful character who would easily fight on part with upper-rank demons without many difficulties despite his young age.

Sanemi Shinazugawa 21 Years Old

Most of the Hashira in demon slayer has weird characters as they stem from individuals who once had tragic lives. Sanemi is not an exception, and at only 21 years old, this means that he has experienced a lot of things at such a young age. He always appears as a hot-blooded and stubborn character who is quick to lash out.

Oldest Demon Slayer


According to one of his favorite quotes, it seems like he has had one tragic childhood. He revealed that he had to kill his mother in order to protect Genya, and he seemed to really care about his family despite all this. One interesting fact that lists Sanemi similar to Muzan is his body weight and height. Muzan has lived for over a millennium but is still as fresh as 21 years old.

Goto 23 Years

As a member of the Kakushi, Goto is amongst the upcoming demon slayers. But he has chosen a different path compared to most who would opt to be demon slayers instead. He has had his hardships growing up and also went through the same trials that demon slayers take to become hashiras. But for some reason, he decided to join the Kakushi.

Oldest Demon Slayer


As a Kakushi, he still wears the same uniform, fully black, and covers most of his face. He played a pivotal role when he discovered a fatally injured Inosuke, Zenitsu, and Tanjiro in the aftermath of the entertainment district arc. This made him develop a lot of respect for them due to their capabilities and bravery.

Kagaya Ubuyashiki 23

As the 97th leader of the Demon Slayer Corps, Kagaya appears to be too young for his role. But he has fulfilled it and managed to accomplish what has taken over a millennium to achieve. He led the demon slayers corps to corner and defeated Muzan even though he was no longer present at the final moments.

Oldest Demon Slayer


Most demon slayers refer to him as master, and he also serves as the head of the Ubuyashiki family. Interestingly, Kagaya became the leader of the demon slayer corps when he was only four years old. And when he was 13, he met Amane, who was 17 years at the time. A certain priest had selected her to become Kagaya’s wife to care for his medical needs. But Kagaya only wanted this to happen if Amane was okay with it.

Tengen Uzui 23

The last Hashira to appear in the anime as we saw his capabilities during the Entertainment district arc. Tengen Uzui seemed to have mastered his skills and was a capable Hashira as he managed to survive the harshest fight we have seen in the anime. Demons always have the upper hand because they regenerate while the demon’s slayers keep the damage in the fight.

Oldest Demon Slayer

Tengen Uzui

And each and every upper-rank demon has unique abilities, so the Hashira goes into a fight without knowing anything about their abilities. And by the time they figure out a way to defeat them, then they are already too late, and things would end up in their defeat, just like we saw when demon slayers as powerful as the Hashira are easily defeated.

Gyomei Himejima 27 Years

Gyomei appears as the largest in body size amongst the Hashira, and this fits his title as the Stone Hashira. He is also one of the tallest characters in the entire series and easily stands way above the rest of the Hashira. He has a powerfully built stature with a muscular body with a prominent scar that runs across his forehead.

Oldest Demon Slayer


Gyomei is amongst the older demon slayers, and Hashira, as most of them, are still of a young age. Most demon slayers and Hashiras are in their early twenties, while Gyomei is in his late twenties so he is quite knowledgeable and experienced due to his older age with respect to his fellow Hashira.

Hantengu 113+ Years

Looking into the ages of the demons, they live more years compared to humans as they can easily live over a hundred years old. The oldest demon slayer to be known lived for around eighty years at his best. And at that, his skills have dwindled to a point were he was finally defeated in battle.

Oldest Demon Slayer


But for the demons, we have seen that they have been in existence for millenniums and have killed several demon slayers. It is surprising how easily demons managed to kill Hashiras, but to Muzan, this was nothing surprising. So this will go to show that the generation of the Hashira that managed to defeat Muzan was really exceptional and was a once in a millennium occurrence.

Doma 133+ Years

As the second upper-rank demon, Doma is amongst the most powerful of the upper-rank demons, only one place below Michikatsu. And with over a hundred years of experience then, this makes him more formidable. With demons, age doesn’t really mean that they are more powerful, but it is how much of Muzan’s blood they can take that determines their overall powers.

Oldest Demon Slayer


Doma used to hold the position of upper rank six about a century ago. So this means that he recently got the upper rank two spot, and this might be due to the role he played in recruiting Daki and Gyutaro. Doma also has his personal cult that worships him in return for his advice. He also uses it as his place to capture and kill humans.

Akaza 300+ Years

Most demons and their background stories date back to over a century ago. Akaza was also a martial artist before he became a demon, and this took place around a century before the storyline of the name and manga could begin. It is his desire to become stronger that has enabled him to live this long as he finally accepted the offer to become a demon. He believes that the skill she had as a human should be preserved and would usually recruit strong warriors to become demons.

Oldest Demon Slayer


Akaza had a sad past as a young boy growing up. His father was always sick, and has he had no money; he would usually resort to crime so that he could provide medicine for him. And even if he were usually caught and punished for this, he would not stop, and when he heard that, he could become a demon. Then this was a good opportunity for him as he would live forever.

Tamayo 400+ Years

Tamayo is one of the rarest demons you could come across. We have also seen exceptional cases like Nezuko, who were unaffected by sunlight. And in Tamayo’s case, she is a demon whom not even Muzan could control. She is capable of creating more demons by herself, and they would not be affected by Muzan or his powers. But in the end, she was an exceptional demon slayer despite being a demon herself.

Oldest Demon Slayer


She used to be Muzan’s aide several hundreds of years ago. Just like most characters in the story, Muzan once killed her family in the past, and she has been looking for a way to avenge them. In the end, she managed to play a pivotal role and created a drug that helped defeat Muzan and turn Tanjiro back into a human after he was affected by Muzan’s blood.

Kokushibo 450+ Years

On the pinnacle of the demon world, we have Kokushibo right before Muzan himself. All the demons in the anime and manga are somehow created by Muzan as he is the progenitor himself. And amongst those he created. There is no other demon that ranks higher than Kokushibo in every aspect there is. Looking at his past, Kokushibo was once a demon slayer who has invented his own Moon breathing techniques.

Oldest Demon Slayer


But now that he was turned into a demon, then that only complemented his skills as a demon slayer who ended up becoming a demon. All the breathing techniques in the story are derived from the Sun breathing technique that Yochiiro, Kokushibo’s twin brother, created several hundred years ago. And as his counterpart, Kokushibo combines his own breathing techniques with his demon powers, and this has enabled him to hone his skills for more than 450 years that he has lived.

Muzan 1000+ Years

Muzan was the very first demon as he was born frail and with a curse that would not see him live over 20 years of age. And due to his fear of death. He went around looking for a way that could cure his illnesses, and when he finally came across a cure that worked, it ended up turning him into a demon as a side effect. His weaknesses only remained to be direct sunlight, so this would leave him fully operational only during the night.

Oldest Demon Slayer


In his search for the Spider Lilly flower that would give him immunity to the sunlight. He created his own demons that would aid him in the search for immortality. This developed from Muzan’s fear of death, and when he finally found ways to live longer, he never wanted to die. Then we have the entire storyline that the demons slayers and the demons have fought for over a thousand years until Muzan was finally defeated, bringing the entire series to an end.

Demon Slayer Characters and Trivia

There are so many interesting facts about these characters that have appeared to be amongst the oldest in the manga and the anime. Most interestingly, most of these facts and trivia remain unknown to most fans, especially those who strictly follow the anime, since there is still a lot they are yet to know. Let’s look at some of the interesting information about them that is not popularly known:

Muzan Kibutsuji

As the progenitor of the demons, Muzan was born and became a demon in the early 900s during the Heian Period, and this explains why he has lived over a millennium.

Due to his demeanor, immorality, and abusive manner. Muzan used to have five wives who ended up committing suicide. His treatment was so cruel and harsh such that they would end up mentally disturbed.

The Ubuyashiki family that Kagaya Ubuyashiki, the leader of the demon slayer corps in the anime. Is the descendants of Muzan’s original blood relatives. The family was cursed with an unknown incurable and untreatable genetic disease that would kill their family member before turning 30 years.
