Daki

Daki (堕だ姫き, Daki?) was one of the primary antagonists in the Entertainment District Arc of Demon Slayer: Kimetsu no Yaiba. She was a demon affiliated with the Twelve Kizuki, being the secondary holder of the position of Upper Rank Six (上じょう弦げんの陸ろく, Jōgen no Roku?),[5] a position she shared with the primary holder, her older brother, Gyutaro.[6] Over centuries ago during the end of the sengouku period and Edo period, Daki was a human child by the name of Ume (梅うめ, Ume?), who lived in the Rashomon Riverbank of Yoshiwara, the lowest class of the Entertainment District,[7] before she and Gyutaro were turned into demons personally by Doma, who was Upper Rank Six at the time.[8]
