Nakime

Nakime is a supporting antagonist in the Infinity Castle Arc of Demon Slayer: Kimetsu no Yaiba. She was initially a demon who served under Muzan Kibutsuji's command due to owning and controlling the Infinity Castle that he has made his base of operations but after Hantengu's death, she eventually attains the position of Upper Rank Four in the Twelve Kizuki. Nakime is a pale woman with a grayish complexion, who had sharp, blue-stained nails and notably red lips which sharply contrasted the tone of her skin. She had shiny, waist-length hair of a dark brown color, which she wore falling down her back in slight waves that cut off sharply at the ends, with two chin-length strands left to frame her face and long bangs that obscured her large eye set in between them, swept to either side of her nose. Nakime wore a plain black kimono with a white lining, secured with a striped pale brown-striped obi, white socks and no shoes. She was always seen holding a four-stringed wooden biwa with a large bachi pick. Since becoming an Upper Rank, Nakime took to wearing her bangs as to not obscure her face, showing that she possessed a single large, pink-colored eye with the kanji for "Four" etched onto its iris. The upper portion of her face was also revealed, and appeared to be a darker gray color than the rest of her skin with prominent veins surrounding her one eye. Nakime was a mysterious yet cold biwa player who displayed little emotion. She didn't speak unless necessary and, when she did, she was always straightforward and blunt, making her responses as short as possible. Unlike other demons, she shows herself to be genuinely loyal to Muzan and obeys his orders without hesitation or question.
