Daki

A demon in the form of a bewitching beauty, usually disguised as an oiran. At that time, she was the only female among the Upper Rank demons. She has a very wicked and arrogant personality, but in front of her brother, her tone becomes childish, revealing her crybaby nature, and according to Gyuutarou, she is honest and easily influenced.

As an oiran, she wears a kimono, but as a demon, she wears lingerie-style clothing with high exposure, including three-toothed geta and a kimono sash around her body. She has a habit of tilting her head and glaring from below when displeased. She is apparently not very smart, often being told by her real brother Gyuutarou, "You're lacking brains."

She had been lurking in Yoshiwara for nearly a hundred years, disguising herself as various "princess" oiran according to the era. Her modern alias is Warabihime Oiran. She despises ugly humans, repeatedly saying, "Ugly people aren't worth living." Among demons, she is picky, preferring to consume beautiful women. She has a trauma with flames because she was burned alive when she was human.

Her Blood Demon Art involves using "sashes." These sashes are her split forms, and when all are collected, her hair turns silver, and she becomes even stronger. She softens her neck into a sash-like form for defense, making it difficult to behead her, and even if beheaded, she regenerates as Gyuutarou sustains her life.

Her strength alone is far superior to that of the Lower Rank demons but insufficient for an Upper Rank demon. When defeated, Muzan commented, "As expected, Daki was a hindrance." She surpasses Tanjirou Kamado's extreme state with Hinokami Kagura, but is harshly criticized by the Pillar Tengen for being "too weak to be an Upper Rank."

Her human name was "Ume." Born on the lowest levels of the brothel at Rashomon Riverbank. Named after her mother's disease, syphilis, she was almost strangled by her mother who found her hair and eye color creepy but was saved by her brother. However, she was such a beautiful girl from a young age that she was called "Shiraume-chan" because of her hair color. As an adult, Ume became a courtesan, but after she blinded a samurai customer who insulted Gyuutarou with a hairpin, she was burned alive as retaliation and turned into a demon by Douma, along with her brother.

She was tasked by Muzan to kill Nezuko Kamado. Tengen infiltrated his wives into the brothel, and she captured them, also capturing Zenitsu, disguised as a new oiran named Zenko, recognizing him as a demon slayer. She went to Tokito-ya to consume the departing oiran Koinatsu, where she encountered and fought Tanjirou, overwhelming him but struggling against Nezuko, and was easily beheaded by Tengen. After Gyuutarou appeared, she mainly fought Zenitsu and Inosuke. Even after Gyuutarou's left eye was moved to her forehead and powered up, she was beheaded before their coordinated attack.

After being beheaded simultaneously with Gyuutarou, they argued and she disappeared first. In the darkness, she reunited with Gyuutarou in human form and, intending to go to hell alone, reconciled with him, saying, "I'll always be with you," "No matter how many times I'm reborn, I'll be your sister," and they both disappeared into the flames of hell together.
