Every Demon Slayer Characters Age | From Messy To Mature!


Over the years, the popular anime series Demon Slayer has become everyone’s favorite not only because of its entertaining storyline but unique characters as well. It is said that a shonen adaptation’s growth depends on the growth of its characters. The statement holds a lot of truth because Demon Slayer characters’ age and development have certainly helped the series climb to another level of success.

1# How Old Is Muichiro Tokito In Demon Slayer?

1# How Old Is Muichiro Tokito In Demon Slayer?

Muichiro Tokito is one of the youngest characters in Demon Slayer, who was able to achieve a lot at the young age of 14. Being a member of the nine Hashira at such a tender age is not easy, but Muichiro managed to grab the title only after two months of his training. Looking at Tokito’s dedication and exceptional skills, there is no doubt that he is a child prodigy who was born to be a demon slayer. Being the only Mist Breathing User with an extraordinary proficiency certainly speaks a lot about his growth in the series.

Present Age: 14 years

Birthday: August 8

Height: 5’3″

2# How Old Is Nezuko Kamado In Demon Slayer?

Nezuko Kamado

Please don’t get tricked by Nezuko’s cute anime girl looks because she is far more powerful and fearless in reality. Nezuko Kamado is 14-years-old just like Muichiro, but her physical state has not changed much because of the demon curse. Nezuko’s transformation into a demon has certainly affected a lot of traits like her short demeanor and shrinking abilities. However, one of the traits that she never lost while her transformation was the desire to protect her elder brother Tanjiro at all costs. 

Present Age: 14 years

Birthday: December 28

Height: 5’2″

3# How Old Is Inosuke Hashibira In Demon Slayer?

Inosuke Hashibira

You can think of Inosuke Hashibira as Demon Slayer’s Naruto. Why? Just like Naruto, who jumps into a battle without much thinking, Inosukue does the same. Although both he and Naruto can take care of themselves effortlessly, it won’t hurt them to think before jumping. Being paired with Zenitsu does not help him either, as the latter is a crybaby. The fact that Inosuke is always looking for an opponent to fight does not help the pair, and eventually, the two end up in the middle of a crisis.  

Present Age: 15 years

Birthday: April 22

Height: 5’5″

4# How Old Is Tanjiro Kamado In Demon Slayer?

Tanjiro Kamada

Ever since his entry into the show, Tanjiro Kamado is seen driven by rage and anger because of his family’s death and his sister’s transformation into a demon. For a long time, Tanjiro’s life became a horrible nightmare, one that he could not escape even if he wanted to. To avenge his sister and parents, Tanjiro joins the Demon Slayer Corps at a young age, and by the time he turns 15, he finds a way to turn his sister Nezuko back into a human. Tanjiro is one of the most humble characters in the series, but he does not let his humbleness come in the middle of making tough decisions. 

Present Age: 15 years

Birthday: July 14

Height: 5’5″

5# How Old Is Zenitsu Agatsuma In Demon Slayer?

Zenitsu Agatsuma

Don’t be fooled by the charming looks of Zenitsu Agatsuma that make him look younger. Contrary to his childish behavior and bubbly personality, Zenitsu is the oldest companion amongst his friends at 16. Unlike his older brother Tanjiro, Zenitsu is a crybaby with low self-esteem but excellent fighting skills. Zenitsu is a great warrior, but his shyness always overshadows his abilities, and he ends up in a pot of boiling water. Even when Zenitsu steps out of his comfort zone and decides to help, it’s for Nezuko when she isn’t in need of any protection. 

Present Age: 16 years 

Birthday: September 3 

Height: 5’5″

6# How Old Is Shinobu Kocho In Demon Slayer?

Shinobu Kocho

Shinobu can fool everyone by playing the role of a responsible elder sister, but it’s all just a coverup that serves as a barrier for her hatred towards the demons. In reality, the most likable member of the group, Shinobu Kocho, is the most vicious character of the series. Shinobu’s viciousness with both words and weapons stems from the death of her sister, Kanae Kocho. Shinobu’s feelings often seem to overwhelm her, due to which she often becomes a deadly mixture of cheerful and sadistic, bringing an endgame in many ways.  

Present Age: 18 years 

Birthday: February 24

Height: 4’11” 

7# How Old Is Giyu Tomioka In Demon Slayer?

Giyu Tomioka

Giyu Tomioka is the calm and composed senior member of the Demon Slayer Corps who believes more in action and less in petty words. The soon to be 21 year old usually likes to keep it calm with his personality, but his calm soul will fade once anger takes over him. Giyu may not be as confident as he seems to be, but he does his best to monitor Tanjiro’s growth as a Demon Slayer. Most of the time, it’s Shinobu who brings out Giyu’s light-hearted side as she knows how to get under his skin more than any other character on the show. 

Present Age: 21 years 

Birthday: February 8 

Height: 5’9″ 

8# How Old Is Mitsuri Kanroji In Demon Slayer?

 Mitsuri Kanroji

Mitsuri may be younger than the other members of the nine Hashira, but that does not mean she has fewer skills than others. As Mitsuri’s strong suit is love, Flame Hashira Kyojuro taught her the Fire Breathing technique that she later incorporated into her Love Breathing technique. Mitsuri may be soft-spoken and more active than others, but most of the opponents are seen running in the opposite direction when it comes to a fight. Mitsuri was not given much screen time on the show, but now viewers are looking forward to seeing more of her Love Breathing skills.  

Present Age: 19

Birthday: June 1 

Height: 5’6″ 

9# How Old Is Kyojuro Rengoku In Demon Slayer?

 Kyojuro Rengoku

Also known as a big brother in the anime series Demon Slayer, Kyojuro Rengoku easily became everyone’s favorite character because of his charms and good nature. Being the Flame Hashira, Kyojura had a mentor-disciple relationship with almost every other character, including Zenitsu, Tanjiro, and Inosuke. During his final battle, Hashira suffers fatal injuries but manages to accomplish his goal of saving the Mugen train passengers along with his Slayer Corps subordinates. Even after his death, Tanjiro seeks Kyojuro’s advice, giving proof of their undying bond. 

Present Age: 20 years 

Birthday: May 10

10# How Old Is Obanai Iguro In Demon Slayer?

Obanai Iguro

Obanai Iguro’s serpent appearance is a constant reminder of Orochimaru, one of the strongest characters in the Naruto universe. Like Orochimaru, Obonai also has a stronghold on snakes, making him one of the most powerful characters in Demon Slayer. Obanai may have a cold and dismissive personality, but he strictly believes in taking the Demon Slayer code seriously. Due to his less screen time, there is still a lot that viewers don’t know about Obanai, but one thing is clear he does not shy away from demanding more effort from his teammates. 

Present Age: 21 years 

Birthday: September 15

Height: 5’4″ 

11# How Old Is Sanemi Shinazugawa In Demon Slayer?

Sanemi Shinazugawa

Don’t take Sanemi’s gory appearance for his role as a demon in the series. Sanemi Shinazugawa is a Demon Slayer and the third oldest member of the Hashira. Sanemi is one of the most powerful wind Hashira in the Demon Slayer Corps and has pent-up anger for the demons. Sanemi may be an adult with a foul mouth and loud barks, but his battle skills are note-worthy. Sanemi’s famous Wind Breathing technique is terrifying, just like him, and is able of killing any demon in just a few seconds.

12# How Old Is Tengen Uzui In Demon Slayer?

As a teenager, Tengen was tricked by his father to kill a few of his siblings, which ultimately led him to run away and seek his path.

As of now, Gyoemi has only served as a minor character in the series, but you will learn more of him in the upcoming seasons and arcs. Gyomei may seem to be intimidating, but he is a soft guy with a big heart. Due to his past, Gyomei does not like spending his time with people and is mostly seen praying with his prayer beads. Gyoemi is an important pillar of the Demon Slayer Corps, but trusting his comrades is a big task. 

Present Age: 27 years 

Birthday: August 23 

Height: 7’2″ 

14# How Old Is Kanao Tsuyuri In Demon Slayer?

 Kanao Tsuyuri

Kanao Tsuyuri is a major supporting character in Demon Slayer and is probably one of the youngest members of the main cast. Due to her rough upbringing, Kanao also likes to keep to herself and believes in self-preservation. For Kanao, emotions only let the enemies take advantage of a person’s weakness, so she showed little to no feeling at the beginning of the series. With time and support from friends, Kanao has finally started to believe in herself and shows a lot of growth. 

Present Age: 16 years 

Birthday: May 19 

Height: 5’1″

Genya plays the role of Sanemi’s younger brother in the series and has a tragic backstory, just like his brother.

For Genya, his childhood was filled with the images of his demon mother killing all his siblings except Sanemi. The betrayal left a huge impact on Genya’s mind and heart and made him of the toughest demon slayers to work with. 

Present Age: 16

Birthday: January 7 

Height: 5’11” 

16# How Old Is Sabito In Demon Slayer?

Sabito does not have a major appearance in the anime series, but he was of utmost importance as long as he was in the series. Sabito was brought into the series during the early days to help Tanjiro prepare for the final selection exams into the Demon Slayer Corps. Sabito and Tanjiro weren’t ready to work with one another in the beginning, but soon Sabito started liking Tanjiro because of his never-ending hopes and note-worthy capabilities. Later, Sabito becomes a role model for Tanjiro and plays a significant role in his growth.
