The Upper Rank Six Demon, Former Oiran


Daki is one of the primary antagonists in the Entertainment District Arc of Demon Slayer: Kimetsu no Yaiba. She is a demon affiliated with the Twelve Kizuki, holding the secondary position of Upper Rank Six, which she shares with her older brother Gyutaro. Over a century ago, Daki was a human child named Ume who lived in the lowest class of the Entertainment District before being turned into a demon by Doma, who was Upper Rank Six at the time.

Personality and Appearance

Daki is smiling menacingly. She is wearing her usual two-piece kimono

Daki appears tall and curvaceous with lime-green eyes, long eyelashes, and very pale skin. Her hair is initially black but changes to silver with lime green tips. She has a flower-patterned obi wrapped around her waist and wears a revealing two-piece kimono. The kanji for "Upper Rank" is engraved in her left eye, and "Six" in her right.

Daki is prideful, dismissive, and sadistic, enjoying toying with her victims before killing them. She displays childish and bratty tendencies, often throwing tantrums when things don't go her way. Daki is extremely cruel and abusive towards those who displease her, yet shows fanatical loyalty to Muzan. Despite her volatile relationship with her brother Gyutaro, she has a strong, genuine love for him.
