Demon Slayer Characters

Tanjiro Kamado – July 14th

The gentle protagonist of Demon Slayer, Tanjiro was born on July 14th. When he first appeared in episode 1, Tanjiro was 13 years old, and by episode 3, he was 15. No, he didn’t time travel – there was a two-year skip between installments. 

Tanjiro lost his family early to a demon attack. The only surviving family member he had was his sister, Nezuko, who got turned into a demon. To find a cure for her, Tanjiro embarks on the journey of a Demon Slayer. 

Tanjiro’s height is 5’5″ (165 cm). A normal person at the start, his unwavering determination to save his sister and righteous personality help him grow strong enough to contend with his enemies.

Nezuko Kamado – December 28th

We first see Nezuko as a prim and proper young girl at 12 years old. At age 14 after the two-year time skip, she stands at 5’02” (153 cm) in height. 

Muzan turned Nezuko into a demon in the first episode. And demons do not age — which means she is still physically a 12-year-old even after turning 14. Nezuko is usually a shy girl, but she will not hesitate to bear her fangs if her brother is ever in danger. 

Zenitsu Agatsuma – September 3rd

Zenitsu was born on September 3rd. He is one year older than Tanjiro at 16, but falls short of him in height by half a centimeter at 5’5″ (164.5 cm). 

Zenitsu is a strong Demon Slayer. He is equipped with both technique and physician capability, with his only flaw being his fragile mentality. He cries too easily and tends to avoid confrontation with an enemy, preferring to leave a fight to others. His real combat potential slips out when he blacks out and doesn’t remember anything afterward. However, he changes as the series progresses and becomes someone his friends can rely on.

Inosuke Hashibira – April 22nd

Inosuke is like a boar: straightforward and aggressive. He is 15 years old, the same age as Tanjiro. He might look like a bishonen (beautiful boy) on the outside, but he is a savage beast who will not hesitate to rip his enemies to shreds. Inosuke is 5’5″ (164 cm).

Inosuke was raised by boars, so he lacked human contact for almost all his life. He often picks fights with anyone who rubs him the wrong way. His swordsmanship and enhanced flexibility make him a force to be reckoned with in combat.

Kanao Tsuyuri – May 19th

Kanao is the definition of silent but deadly. She is a strong but emotionally detached girl who hardly opens her heart to anyone. Kanao was abused by her parents when she was young, so she is afraid to connect with others. However, as the story progresses, she becomes more friendly and caring toward others.

Kanao is 16 years old, and her birthday is May 19th. She has a short stature at only 5’1″ (156 cm). Kanao often carries herself with a calm and serene demeanor that makes anyone watching enamored with her.

Genya Shinazugawa – January 7th

Don’t let this guy’s appearance fool you. He might look like an old man, but is only 16. His scars, intimidating glare, and towering height of 5’11” (180 cm) make him look older than his actual age. 

Genya’s personality is as straightforward as his looks. He has a foul mouth and gets angry quickly, but his soft side awakens after he encounters Tanjiro and his friends. The main source of all his problems was his turbulent relationship with his brother, whom he believed killed their mother. He later becomes good friends with Tanjiro. 

Sanemi Shinazugawa – November 9th

Sanemi is a Hashira (Pillar) and one of the strongest Demon Slayers. He, too, like his brother, has an intimidating appearance and aggressive personality. Sanemi was born on November 9th and is 21 years old, making him a senior member of the Corps. He is a little shorter than his brother, reaching 5’10” (179 cm).

Sanemi didn’t leave a good impression on the audience. With his spiteful remarks toward our main characters and his murder of his mother, it would be strange not to hate him. However, everything turns out to be a misunderstanding, and we find that he is indeed a good person at heart. 

Giyu Tomioka – February 8th

Giyu Tomioka is like a mentor to Tanjiro and one of the few characters to appear early on in the series. In the first two episodes, he is 19 years old. Giyu was born on February 8th, and his height is 5’9″ (176 cm). 

As the Water Hashira (Pillar), Giyu is a calm and serene man — almost like water. However, he lacks confidence in his abilities, which is why he spends plenty of time training. Despite this, he is significantly strong, proven by the fact that he decapitated Rui quite effortlessly. He is the exact opposite of Sanemi, causing the two to often butt heads. 

Shinobu Kocho – February 24th

Shinobu is poisonous both literally and figuratively. She has a beautiful appearance, but her blunt manner of speaking has hurt many people more than once. 

Shinobu is 18 years old, making her only 2 years older than Tanjiro. Her hatred for demons stems from her sister’s murder at the hands of one. This is one of the reasons why she puts up a facade where she likes to tease others while smiling sweetly.

Despite being only 18 years old, Shinobu is the Insect Hashira and is way more skilled than other girls her age. Her birthday is February 24th and she is shorter than average, with a height of  4’11” (151 cm).

Tengen Uzui – October 31st

Tengen is a big man, standing at 6’6″ (198 cm) tall. He has an eccentric and flashy personality. You wouldn’t expect a guy like him to have such a sad past.

His father was a sociopath who forced his sons to kill each other. After losing most of his brothers, Tengen stopped seeing them as family and joined the Demon Slayer Corps. Tengen was born on October 31st and, at 23, is one of the group’s oldest members. 

Tengen was the Sound Hashira before losing an arm and eye to the Upper Moon Six, Gyutaro. However, he is still strong and supports the main cast from behind. 

Mitsuri Kanroji – June 1st

When you are the Love Hashira, love is the only thing you will think about. Mitsuri is that character. She has a charming personality, beautiful pink hair, and a unique voice so loud that it’s difficult to miss her even when she is hiding. This is why every fan was smitten with her when she first appeared.  

Mitsuri’s birthday is June 1st and she is 19 years old. Her height is 5’6″ (167 cm), making her one of the tallest female characters in the series. Mirsuri’s physical strength is nothing to scoff at, as she can lift a boulder with her bare hands. 

Obanai Iguro – September 15th

Obanai doesn’t disappoint as the Serpent Hashira. He looks just as weird and creepy as a snake. However, he is serious and strict with everyone besides his crush, Mitsuri. Obanai is 21 years old and his birthday is September 15th. He is one of the shortest Hashira at only 5’4″ (162 cm).

Obanai can only see from his right eye, but that doesn’t hinder him in a fight. He has Kaburamaru, a white snake who reads an enemy’s attacks and relays them to him. 

Muichiro Tokito – August 8th

It’s easy to underestimate Muichiro. He is only 14 years old and lacks social skills. However, Muichiro is a genius swordsman who became a Hashira at a young age. He may have no memory of his past, but that doesn’t prevent him from dicing demons to pieces as the Mist Hashira. 

Although he looks like a girl, Muichiro is a growing boy with a height of  5’3″ (160 cm).

Gyomei Himejima – August 23rd

Gyomei has yet to do much in the series, but he is still an important character to watch for. He is the Stone Hashira and the current strongest Demon Slayer. His height is 7’2″ (220 cm), making him the tallest in the series. He is a dedicated person whose only goal is to defeat Muzan and bring peace. Despite being so strong, Gyomei is often quiet and reserved – a gentle giant.

Kyojuro Rengoku – May 10th

A fiery hair with a fiery personality, the former Fire Hashira Rengoku brought a fresh feel to a Hashira lineup full of tragic backstories. While Rengoku had a story to tell as well, he always strived to become stronger. He was 5’10” (177 cm) tall.

Rengoku was born on May 10th and was 20 years old when he died in a fight against Upper Moon Three, Akaza. His way of living influenced Tanjiro and helped him grow stronger later in the series. To this day, Rengoku is still an inspiration to Tanjiro.

Aoi Kanzaki – Unknown

Aoi has no confidence in her abilities. That’s why she decided to work at the Butterfly Mansion despite passing the Final Selection. She is over 16 years old and is 5’4″ (162 cm). She is close to Shinobu and Kanao. Although weaker than Tanjiro and the group, Aoi can chew them out if they go overboard with the pranks. 

Sabito – Unknown

Sabito was the ruthless teacher who beat the basics of Demon Slaying into Tanjiro. Through this, we learn that he is a capable fighter even though he is only 13. Initially, he thought Tanjiro wouldn’t pass the Final Selection, but later changed his mind. 

At the end of the training arc, we learn that Sabito had already failed to become a Demon Slayer Corps member and died.

Tamayo – July 2nd

Tamayo looks outwardly beautiful, but she is over 500 years old. Muzan made her into a demon and she acted like his assistant until the Twelve Kizuki’s (Twelve Demon Moons) formation. Then, she betrays Muzan and tries to kill him, only to fail. Tamayo is still a capable fighter thanks to her 500-plus years of experience.

Tamayo has a short stature reaching 4’11” (150 cm) and her birthday is July 2nd. She is obsessed with cleanliness, and when something dirty is around, she can’t put her mind at ease until it’s dealt with. 

Kagaya Ubuyashiki – Unknown

Kagaya is the current leader of the Demon Slayer Corps. At 23, he is younger than many members but still commands immense respect from his subordinates, as they call him Oyakata-sama (Master). As a member of the Ubuyashiki family, Kagaya has the power of foresight, which helps him prevent many disasters. He can also calm people down just by talking.

Muzan Kibutsuji – Unknown

Muzan is the main antagonist of Demon Slayer and is over 10,000 years old. One of the Demon Slayer Corps’ primary objectives is to hunt him down and end the demons’ reign of terror. 

Whether demon or human, Muzan is ruthless to everyone. He is also responsible for massacring Tanjiro’s family and turning Nezuko into a demon. He is 5’10” (179 cm) tall. A fun fact: Muzan can transform, an ability he uses to hide from the Demon Slayers.

Rui – Unknown

Rui has the appearance of a 13-year-old boy, but he is over 30. Muzan turned him into a demon when he was just a sickly kid.  His parents tried to kill him with tears in their eyes to stop him from becoming a monster. In retaliation, he killed and devoured them — an event that would later give him a twisted obsession with family. Rui stopped growing after transforming into a demon, so he will never be taller than 4’5″ (135 cm). 

Akaza – Unknown

Akaza would’ve been a chill guy if not for him being the Upper Moon Three and the one who killed Rengoku. Although Rengoku lost to him, he didn’t die before taking an arm with him. Their fight left quite an impression on both the audience and Tanjiro. Akaza is more than 200 years old with a height of 5’8″ (173 cm). 

Daki – Unknown

Daki is approximately 113 years old, making her one of the youngest demons – but she is no less brutal. She has a sadistic nature and likes to torture her prey before killing them. Her ruthless nature stemmed from her time as a human when she was almost burned alive, only surviving because her brother turned her into a demon. 

Gyutaro – Unknown

Although older than his sister, Gyutaro is a younger demon of over 126 years of age. Daki is the only one he cares about, and he stays inside her until she needs his help.

Most demons are ugly, but Gyutaro has the others beat when it comes to who has the worst looks. His fighting style is just as gruesome. Gyutaro uses sickles made of his flesh and blood in battle (talk about creepy). Since his blood is poisonous, he’s a tricky opponent to face. 

Doma – Unknown

Doma is the second-strongest demon (third if you count Muzan), with his rank being Upper Moon Two. It’s safe to say that he has the worst personality among the Twelve Kizuki. A psychopath with no emotion, he kills for the sake of it. Doma is more than 133 years old and has a height of 6’2″ (187 cm).
