Tamayo

A female demon who has lived for over four hundred years. Her physical age is 19. She usually works as a doctor.

Originally on the brink of death due to illness, she was turned into a demon by Muzan, which allowed her to survive. However, this led her to kill and eat her beloved son and husband, and out of resentment, she opposes the Muzan faction and is pursued. She managed to break Muzan's curse on her own and escape his control, allowing her to live by drinking only small amounts of blood without consuming humans. She can cast illusions through her own blood.

She asks Tanjirou to collect demon blood in order to establish a method to turn demons back into humans. To evade Muzan's pursuit while hiding her demon identity, she cannot stay in one place for long.

While researching Nezuko and the blood of the Twelve Kizuki, she succeeds in restoring the ego of humans turned into demons and predicts that Nezuko will soon overcome the sun. Around the same time Nezuko overcomes sunlight, she is approached by Yoriichi and sets a trap for Muzan. She later confronts Muzan with grievances but is absorbed and killed by him. However, the drugs she released against Muzan—turning demons back into humans, accelerating aging, inhibiting division, and destroying cells—greatly contributed to the subjugation of Muzan.

Continues from the short story "Excessive Hunting."

List of Techniques

Bewitching Blood (Wakuchi)

Tamayo's Blood Demon Art. Activates by injuring herself and bleeding. The smell of her blood causes hallucinations indiscriminately within its range.

Visionary Dream Fragrance (Shikaku Mugen no Kou)

A mysterious pattern appears in the vision of those who smell it, rendering them immobile.

Daylight Demon Fragrance (Hakujitsu no Makou)

Functions like a truth serum, impairing brain function in those who smell it and extracting information. It makes it impossible for them to lie or keep secrets. Harmful to humans, so they must not inhale it. Can successfully induce an "curse" during interrogation of demons.

Unobstructed Fragrance (Yūzūmuge no Kou)

A joke from a spin-off four-panel comic. An attempt to correct Tanjirou's overly serious and rigid personality fails, resulting only in foolish statements.

Flesh Seed

Spreads countless seeds made of flesh, from which numerous black thorns branch out and impale the opponent.

Originally a Blood Demon Art of a man turned into a demon by Muzan in Asakusa, which Tamayo analyzed and replicated.

Used this technique to restrain Muzan at the Ubuyashiki residence, creating time to administer four types of drugs against Muzan.
