Demon Slayer Characters: Ages, Birthdays, And Heights

Even though Koyoharu Gotouge’s Demon Slayer: Kimetsu no Yaiba shonen manga ended in 2020 after 23 volumes, the series has remained firmly in the spotlight thanks to ufotable’s anime. While hardly unusual for an adaptation to eclipse the source material’s popularity, Demon Slayer is a fairly unique case since the anime turned an internationally unknown property into a household name. Gotouge’s story was not some hidden gem known by only the most committed of Weekly Shonen Jump readers, but it arguably did not have the same level of exposure as My Hero Academia or Attack on Titan. The anime not only pushed the property into that ballpark but, in some ways, exceeded both of those juggernauts.

Funnily enough, even the anime had a slow rise in popularity. The first season did not draw extraordinary attention until episode 19, which saw ufotable elevate the animation from “TV great” to “all-time great.” From this moment onwards, Demon Slayers broke into the mainstream, becoming one of the biggest shonen anime of all time. At this point, the series has produced four pretty great seasons, combining for an impressive 63 episodes. Now, admittedly, seasons 3 and 4 were slight stepbacks compared to their predecessors, with the former’s Swordsmith Village arc feeling too similar to season 2’s Entertainment District storyline. Season 4’s Hashira Training arc mostly served to set up the final battle, which will be adapted into a movie trilogy. Considering 2020’s Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train was one of the highest-grossing anime movies ever, this decision makes sense.

While ufotable’s animation and action tend to steal the spotlight, Demon Slayer‘s characters are iconic and beloved in their own right. Consequently, fans may wish to know general information like “How old is Tanjiro?” or “When are the Demon Slayers’ birthdays?”

Although they will be kept to a minimum, spoilers will not be completely avoidable.

Updated May 18, 2025, by Mark Sammut: Demon Slayer: Infinity Castle is steadily nearing, with the movie set to debut later in 2025. This release will mark the first chapter of a trilogy that will bring the adaptation to a close. While it might not attract the same attention as a series, the film should be a big hit, at least going by the success of Mugen Train. This article has been expanded to include clearer data for each Demon Slayer character.

Demon Slayer Statistics Chart

Demon Slayer‘s anime still has a ways to go before it ends, and as Tanjiro’s journey continues, he will only meet more and more interesting figures. While not all are born equal, each Demon Slayer character brings something new to the plate. They all have something that allows them to shine, be it a fascinating power, an intimidating disposition, or a sense of humor.

As the anime’s roster expands, this article will do the same to reflect the series’ progress. Therefore, to make the information as readily available as possible, the following table covers the age, birthday, and height of the most important Demon Slayer characters.

Ages are based on each character’s first appearance. Also, click on a character’s name to go to their section containing more information.

Tanjiro Kamado

Demon Slayer – A Never-Say-Die Protagonist Who Will Do Anything To Protect His Sister

Demon Slayer‘s main character, Tanjiro could very well make or break the anime for a lot of people, even if he tends to share the spotlight with another character in most arcs. He is the story’s ever-present constant, along with acting as the audience surrogate through whom they become immersed in the war between humans and demons. Kind-hearted, honest, and willing to do everything for his sister, Tanjiro is a fairly typical example of a shonen protagonist, albeit one that is executed competently.

At the beginning of the series, Tanjiro arrives home to learn that his family has been slaughtered by a demon, with the only survivor being his sister, Nezuko. Unfortunately, she has been partially turned into a demon, a tragedy her brother is determined to reverse. This drive to protect his sibling puts Tanjiro at odds with the Demon Slayer Corps, although he eventually convinces them to spare Nezuko for the time being.

While his personality is safe for this type of story, Tanjiro is relatively ruthless and does not hold back in fights against demons, knowing well that any hesitation could result in his death. His determination is admirable.

Nezuko Kamado

Demon – Supported By Tanjiro, Nezuko Fights To Keep A Hold Of Her Remaining Humanity, All The While Surpassing A Few Limitations Associated With Demons

One day, while Tanjiro was away, Nezuko watched the rest of her family be butchered by a demon. The young girl almost faced the same fate, but she ended up becoming a demon herself; however, Tanjiro made it his mission to reverse Nezuko’s condition and turn her back into a human.

Demon Slayer only provides a snippet of Nezuko’s time as a human, showing her to be rather sweet and altruistic. Following her transformation, Nezuko became very different as she developed traits synonymous with demons, including overwhelming strength and a thirst for blood. She also largely lost the ability to speak and spent a long time in isolation due to a weakness to sunlight, only showing up sporadically. As such, her personality can be harder to pin down than some of the anime’s other characters, although her love for her brother is obvious.

Zenitsu Agatsuma

Demon Slayer – Scared And Loud, Zenitsu Is An Acquired Taste Who Becomes More Palpable When He Is Asleep

Probably the most divisive character, Zenitsu seems to be way more popular with Japanese than with Western audiences. As effectively the second protagonist after Tanjiro (Nezuko has too little agency), Zenitsu gets a lot of screentime, and he tends to serve as comic relief in most situations. He is loud, obnoxious, and rather gutless, with his instinct being to flee rather than fight. He recognizes quickly when an enemy is beyond his abilities, and he tends to give in to his fear. To be fair, that is an understandable reaction, even if it can get grating after a while.

Zenitsu has one particular strange quirk. When he falls asleep, he becomes pretty deadly. Yeah, as long as he is not conscious, he can put up a fight against most enemies. As the story approaches its climax, Zenitsu matures quite a bit and fully commits to the Demon Slayer Corps, a turn that is largely for the better.

Inosuke Hashibira

Demon Slayer – Aggressive And Capable, Inosuke Barges Head First Into Most Fights, At Least In The Early Arcs

Arguably having one of the most eye-catching designs out of any Demon Slayer character, Inosuke leaves a strong first impression due to wearing a boar head, which is pretty unique since no other hero has that type of aesthetic. More importantly, Inosuke’s personality reflects his fashion sense, with the quick-to-anger character using pretty much any opportunity to get involved in an argument or fight. While a bit much at times, he is generally dependable and 100% committed to the Hashira’s cause.

Inosuke’s action-first mentality to situations means that he often jumps head-first into encounters without thinking about the risk. While this approach could backfire since he consistently faces off against enemies stronger than him, it also means that Inosuke does not hesitate when going up against powerful demons. He also notably changes throughout the anime, mellowing out quite a lot as the story progresses.

Kanao Tsuyuri

Demon Slayer – This Practioner Of Flower Breathing Should Not Be Underestimated

Kanao has large, gentle-looking pink eyes and thin black hair worn in a ponytail. A rough upbringing taught Kanao to completely close herself off as a way of self-preservation. For the longest time, Kanao showed little to no emotion and refused to make any decisions for herself, opting to leave such matters to others or chance.

As with most heroic Demon Slayer characters, Kanao matures quite a bit as the series progresses, although only hints of that have been provided by the anime. She has also taken a backseat in recent arcs, only appearing for a few minutes in seasons 2 and 3.

Genya Shinazugawa

Demon Slayer – Chasing The Wind Hashira’s Shadow, Genya Struggles With Feelings Of Inadequacy, Even If He Tries To Mask It

Another character with a tragic backstory, Genya witnessed his siblings being murdered by his demonized mother. He also saw his only surviving brother, Sanemi, kill his mother. Although he cannot use Breathing Techniques, Genya is a strong fighter who has a talent for absorbing demon abilities.

Genya’s hot-headed nature doesn’t make him the easiest Demon Slayer to work with, at least during the early stages of the anime. However, Genya becomes slightly more sociable as the story goes on, even if he still reacts aggressively to Tanjiro’s presence during the Swordsmith Village arc.

Sanemi Shinazugawa

Demon Slayer, Wind Hashira – Unapproachable But Vicious, Sanemi’s Hatred For Demons Knows No Limits

Genya’s brother, Sanemi is the Wind Hashira and a force to be reckoned with. As a child, Sanemi went through a personal tragedy that forced him to shut down emotionally and eventually cut off people like his brother from his life. This same experience installed an unflinching hatred for demonkind in the Wind Hashira, and this fire has shown no signs of weakening.

Sanemi is one of the older human characters in Demon Slayer, although it would be an exaggeration to describe him as one of the most mature. That’s not to say the Wind Hashira is juvenile, but his stubbornness tends to shine through whenever something comes along that challenges his worldview.

Although a presence in earlier arcs, Sanemi received more of a spotlight during the Hashira Training Arc, and that statement extends to most of the strongest Hashira. With a “difficult” personality and a tendency to resort to violence before anything else, Sanemi is not the easiest person to be around, and he treats his brother, Genya, with indifference or disdain. He also has a rocky relationship with Tanjiro, with neither person being fond of the other.

Giyu Tomioka

Demon Slayer, Water Hashira – Overcoming Impostor Syndrome With The Help Of A Few Allies

Not one to waste words, Giyu keeps things close to the chest and believes others should follow suit. As a child, Giyu was saved from a demon by his sister at the cost of her own life; frustratingly for the child, Giyu’s attempts to inform people of what happened only resulted in him being ostracized.

As a rather senior member of the Demon Slayer Corps, Giyu presents a strong and aloof figure, although he isn’t quite as confident as he appears to be. After spending roughly three seasons on the back burner, the Water Hashira was finally spotlighted in Spring 2024’s Hashira Training Arc, providing insight into his stand-off nature and the guilt he has been carrying with him for years. After his sister’s death, the desolate Giyu found a second lease on life through Sabito, and the two children struck an endearing friendship. As both were training to become Demon Slayers, they entered the Final Selection exam together, the same one that resulted in Sabito’s death. Filled with self-hatred over his friend’s death and the fact he passed the exam despite failing to kill a single demon, Giyu believed himself to be unworthy of the Water Hashira position. It is a classic tale of impostor syndrome.

Shinobu Kocho

Demon Slayer, Insect Hashira – Just This Book By Her Cover At Your Own Peril

At first glance, Shinobu appears to be the friendliest and most likable member of the Demon Slayer Corps. She always has a smile on her face and seems up for a good joke. However, this is simply a coping mechanism to restrain her uncontrollable hatred for demons stemming from the death of her sister, Kanae Kocho.

Shinobu can be unbelievably vicious, both with a blade and words. This Demon Slayer character can reduce the strongest of warriors to insecure puddles of mush with a few choice sentences. She will also grin while doing it. Although perhaps not the most obviously powerful member of the Hashira, Shinobu is a definite threat to nearly any demon, largely thanks to her quick thinking and medical knowledge. The latter manifests in her usage of poison as a weapon.

Tengen Uzui

Ex-Demon Slayer, Sound Hashira – Stylish And Dedicated To His Wives, The Former Hashira Is An All-Around Force Of Nature

In a nice change of pace, Tengen’s backstory doesn’t have all that much to do with demons; that said, it is still tragic. Born into a ninja clan and trained by his cruel father, Tengen was thought to only ever seek self-fulfillment, regardless of the cost to anyone else. Tricked by his parent into killing a few of his siblings, Tengen eventually left the nest to try and carve out a path for himself.

Tengen’s personality is a bit all over the place, courtesy of his harsh childhood and attempts to escape his father’s teachings. That said, he does have generally good intentions, even if his methods tend to be rather aggressive. When he sets out to investigate the Entertainment District, Tengen tries to recruit Aoi Kanzaki despite her being terrified at the prospect of heading into the field, and he only changes his mind when Tanjiro, Zenitsu, and Inosuke demand to take her place. However, his actions are driven by a genuine fear that his wives, who previously infiltrated the district, might be in danger. Once he realizes that an Upper Rank demon might be involved, Tengen asks Tanjiro and the rest to leave to ensure their survival.
