Kimetsu no Yaiba, or Demon Slayer, is a manga of Japanese origin that has an adaptation of anime format series and movies. The story centers on Tanjiro Kamado, a young man from a humble family who lives in the mountains and is recruited to kill demons. Throughout history, we can see a character named Tamayo, but who is she?
Tamayo is a character from the famous Japanese anime Demon Slayer. She was once a skilled doctor until Muzan Kibutsuji, the main antagonist in history and the king of demons also turned her into a demon. She has a dispute with Muzan because she is interested in being a better demon.
If you want to know more about Tamayo’s character, history, motives, age, and relationship with Muzan Kibutsuji, keep reading this article.
Tamayo Demon Slayer
Tamayo used to be a housewife woman with a husband and children. On one occasion, she faced a life-threatening situation and desperately searched for a cure. That’s when Muzan Kibutsuji comes into your life, offering you a “solution” or “cure” to your problem.
Thus, under a lie, it was that Muzan turned Tamayo into a demon. She lost all her emotions, humanity, and memories when she was converted and murdered her husband, children, and several citizens of the town where they lived.
Tamayo is a demon with unique abilities. We could start with the fact that she is one of the few demons able to control her desire to feed on human flesh. She created a different method: she buys her blood from the most economically vulnerable humans, enough to feed herself but not enough to kill them.
This is due to her desire not to harm humans, eventually leading her to join Tanjiro Kamado, the main character in the story, to defeat Muzan Kibutsuji.

Because Muzan Kibutsuji is the king of demons, he has immense power over them. However, Tamayo looked for a way to break free from that submission, being able to reveal herself against Muzan, showing how strong she is.
We already know that in her past life, she was a doctor. Still, due to her age, she has acquired a lot of knowledge in medicine and the area of demons. She is probably the character who knows the most about demons in the manga. Throughout the story, we can see his desire to create a medicine that can turn demons back into humans, being a welcome help to the Demon Slayers.
When newly converted, she attempted to kill Muzan, which failed due to her inexperience and lack of skills and strength. Later, she became Muzan’s subordinate, becoming his assistant. And although only Kibutsuji has the power to turn humans into demons, Tamayo was able to turn a patient she cared for, who was on the brink of death, named Yushiro. Later, Yushiro became Tamayo’s assistant and apprentice.
Tamayo has remarkable skills as a doctor that have helped more than one person throughout history. Apart from that, Tamayo can create hallucinations in her blood and influence brain cells to decrease so that her victim does not lie. Her powers were only used at the convenience of the Demon Slayers, whom she allied with for a chance to defeat Muzan.
How Old Is Tamayo?
Tamayo’s exact age is unknown, but he is estimated at least 500 years old. This assumption stems from Tamayo being present while Muzan Kibutsuji was fighting Yoriichi Tsugikuni, a legendary Demon Slayer belonging to the Demon Slayer Corps during the Sengoku Era, in the battle that nearly cost Muzan his life.
However, Tamayo’s physical appearance is between 19 and 25 years old, which was the time when she was converted.
Who Is Tamayo’s Voice Actress?
Tamayo has two actresses who supply her voices, depending on whether you watch the Japanese or the American version.

Was Tamayo Muzan’s Wife?
Tamayo is not and was not Muzan’s wife. Tamayo was married before she became a demon, but she did not marry Muzan Kibutsuji. Kibutsuji and Tamayo’s relationship could be said to be professional since Muzan was Tamayo’s teacher.

Does Muzan Love Tamayo?
Muzan Kibutsuji and Tamayo had an immense familiarity. However, it was not loved that existed between them. In the story, it is unclear what Muzan’s real feelings are toward Tamayo. Still, we can clearly see Tamayo’s hatred, contempt, and resentment toward Kibutsuji.
Is Tamayo Dead?
Muzan killed Tamayo in a battle where the Demon Slayers united against Muzan Kibutsuji. Tamayo is determined to die and pay for her sins by killing innocent people. Even in her last moments, when Muzan is crushing her head, Tamayo maintains her posture and begs him to take her along with her family.
Why Can Tamayo Say Kibutsuji?
Tamayo can say Kibutsuji without anything happening to her because she found a way to free herself from Muzan Kibutsuji’s curse. How she did it is unclear, but she is the only demon who can resist Muzan without consequence.
Why Does Tamayo Hate Muzan?
The reason Tamayo hates Muzan is simple: their story. Tamayo had a terminal illness for which she sought a cure to see her children grow up. Due to this, Muzan took advantage of the moment to trick Tamayo with a “cure” and turned her into a demon.
This caused her to murder her entire family, and her cure was not worth it. Since then, Tamayo has been looking for a way to avenge the death of her family by killing Muzan.
A Final Thought About Tamayo
Tamayo is a unique character in the Demon Slayer story. Her strength, skills, knowledge and wisdom, and kind, docile, and dedicated personality have won the hearts of many fans of this manga. She has impressive powers and abilities not seen in other characters, such as her resistance to Muzan’s curse.
She also has the peculiarity of clinging to her human part, feeling empathy, pain, and hope, and even allying with humans. And, although in the audiovisual adaptation of the manga, its fate is still unknown, in the comic, you can see her horrible end at the hands of their arch-enemy.
