Tamayo is one of the demons in Demon Slayer: Kimetsu no Yaiba. She is one of those demons who doesn’t go on a spree to kill humans and devotes more to help them instead.

Apart from being a demon, she is an incredible doctor with excellent skills in medicine. She is also close to Tanjiro and Nezuko.

Tamayo helps the Demon Slayer Corps during the Infinity Castle Arc and Sunrise Countdown Arc. She aids Shinobu and other Hashiras in developing a poison that would prove to be incredibly helpful in defeating the demon king, Muzan.

Infinity Castle Arc: Contributions In Killing Muzan

Tamayo reappears after Muzan’s raid on the Ubuyashiki home, after Kagaya Ubuyashiki, his wife, and two daughters blew Muzan and themselves up. At this time, Tamayo’s Flesh Seed strike pierces Muzan’s body as he recovers from the explosion. Muzan understands he’s been restrained by a Blood Demon Art and tries to absorb the spikes, but Tamayo punches him in the stomach. He asks her why she’s here, and she says that her fist holds a medication that can change a Demon into a human. He denies it, but Tamayo smiles menacingly and claims it’s real, but she didn’t do it alone.

Muzan says Tamayo is a stubborn lady whose hatred is unreasonable because she killed her family, not him. Tamayo yells that she wouldn’t have become a Demon if she realized that would be the result, as all she wanted was to heal from her condition and see her kids grow up. He reminds her that she killed more humans after her family as she slipped into despair. She says that’s why she must pay for her sins and why she and Muzan must die right then, yelling for Gyomei Himejima to kill them. Stone Hashira’s spiky flail decapitates Muzan. Gyomei resolves to detain Muzan until morning so the sun can disintegrate him when he regenerates his lost limb.

Tamayo’s Death

Muzan holds up Tamayo’s head after quickly killing the Demon Slayer Corps that were sent after him. As he looks her in the eyes, he says that the drug didn’t work. Tamayo tells Muzan to go to hell, but he says he won’t because hundreds of other people have said the same thing. In her last moments, Tamayo begs Muzan to return her family. He tells her to go back to the family she killed and then crushes her head, eventually killing off Tamayo.

Tamayo – Abilities

Tamayo was an average demon and didn’t play a significant role in fighting off anyone.

At one point, she tried to kill Muzan and failed, but even though, Muzan didn’t kill her. Also, Tamayo has been a demon with Muzan even before the Twelve Kizuki. You can even say that she is one of the oldest demons we see in the series, which is as old as Yoriichi and Kokushibo.

Medical Skills

Tamayo was very smart when it came to medicine and drugs. She was able to change her own body so that she could live on just a tiny amount of human blood. She was also able to turn Yushiro into a Demon without using Muzan’s blood, and she was able to reverse the process when she was treating the man they met in the Asakusa Arc.

Tamayo was also able to help Shinobu Kocho fill her body with deadly Wisteria poison without it making her sick at all. This is a strategy that the Insect Hashira would later use successfully against Doma, who was Upper-Rank Two.

Anti-Blood Demon Coagulant

Tamayo made this medicine to stop the Blood Demon Art of a demon from progressing into the body and killing off the person gradually.

Yushiro gave this medicine to Zenitsu Agatsuma to help him get better after he fought Kaigaku and was struck several times by his blood demon art.

Anti-Muzan Drug

It turned out that Tamayo, working with Yushiro and Shinobu Kocho, had made a powerful, four-stage drug that could severely weaken Muzan Kibutsuji. Once he took it, its effects would be strong enough to hurt him even though he was very strong and had a lot of physical abilities.

Tamayo Blood Demon Art: Spell Casting

The main thing Tamayo can do is draw blood from herself and use it to cast spells that have different effects on her targets. It has various effects and can assist others in a great way.

Blood Bewitchment

Tamayo made a branch of blood techniques that required her to draw her own blood and then use the blood scent to make her targets do or react in many different ways. It can affect a variety of targets and is suitable for crowd control.

Scent of Illusory Blood, Visual Dream

A hallucination that makes beautiful flower patterns around the person, making it hard for them to see.

Magical Aroma of Daylight

Acts as a truth serum by slowing down the brain, which makes the person tell the truth and not keep their secrets. It can be bad for people.

Flesh Seeds

Tamayo uses her own flesh and blood to make many tiny flesh seeds that surround the person she wants to hurt. The seeds then explode and grow into colossal flesh trees with many sharp branches that pierce and hold her target.

This technique was strong enough to stop Muzan, even if only for a moment.

Tamayo Personality

Tamayo is a kind, wise, and incredibly smart person. She spent most of her life studying the science behind demons and how they change into other things. This made her one of the most knowledgeable people in the series about the subject.

Even though the relationship between humans and demons is usually pretty bad, she was very kind to humans. She made it her mission to help hurt or sick people, including Tanjiro Kamado, with her extensive medical knowledge.
