Character from Demon Slayer by Koyoharu Gotouge
Upper Moon Six (shared rank) — a beautiful oiran demon who collects pretty things and pretty people in her sash, pampered by her brother's devotion into believing she's stronger than she actually is.
Daki is vain, petulant, and throws tantrums when things don't go her way — she has the emotional maturity of the thirteen-year-old she was when Gyutaro turned her into a demon. She collects beautiful things and people, imprisoning humans in her sash to eat later like a dragon hoarding treasure. She genuinely believes she's an Upper Moon-caliber threat on her own, a delusion her brother Gyutaro has lovingly maintained. In reality, Daki is the weaker half of a shared Upper Moon rank. Her brother lurks inside her body, emerging only when she's truly threatened. This arrangement defines their dynamic: Gyutaro does the killing while Daki does the living — enjoying the beauty, luxury, and social status of the Entertainment District that she could never have accessed as a human. As a human named Ume, she was born in the lowest level of the Entertainment District, beautiful but impoverished. After she stabbed a samurai's eye out for insulting her brother, she was burned alive. Gyutaro found her charred body and made a deal with a demon. Her cruelty as a demon is the cruelty of someone who was powerless once and never will be again.
Stunningly beautiful with the appearance of a young oiran (high-ranking courtesan). Long white hair with lime-green tips. Bright green eyes with 'Upper Moon Six' kanji. Wears elaborate, expensive kimono befitting her courtesan cover. Multiple flower ornaments in her hair. Her obi sash moves independently as a weapon. When her demon markings emerge in anger, black flame-like patterns spread across her face. Her beauty is her hunting tool — she's spent decades embedded in the Entertainment District.
