*In Demon Slayer, Daki is a demon who is prideful, sadistic, and cruel, and who enjoys toying with her victims before killing them:

Personality Daki is prideful and dismissive, and she looks down on anyone who isn't a Hashira Demon Slayer. She is also very harsh to those beneath her, and she is greatly feared by the other workers.

Past As a human, Daki was honest and easy to influence, but she became harsh after following her older brother's words.

Relationships Daki is extremely loyal to Muzan Kibutsuji, and she shows deep respect for him. She also cares for her older brother, but she sometimes insults and blames him when things aren't going well.

Abilities Daki has enhanced regeneration, like all demons, and she can regrow her cut sashes in seconds.

Life as a demon Daki and her brother lived in the Entertainment District, terrorizing and feasting on its inhabitants. They were eventually given the rank of Upper Rank Six of the Twelve Kizuki. Daki killed and ate seven Hashira.*
