Nakime

left|thumb|Nakime's silent and aloof demeanour. Unlike most demons, Nakime was not particularly violent or sadistic, and instead is aloof and taciturn, almost never speaking and displaying little to no emotion or will outside of obeying orders. She was extremely loyal to Muzan, listening and following his every order faultlessly which was something he appreciated; in fact, her unwavering loyalty to him marks one of the very few instances Muzan ever complimented an individual, though it seemed more likely that he was satisfied to have a powerful tool to use at his disposal. Despite this outwardly one-sided relationship, Nakime graciously accepted his words and told her master she was honored to be of great use to him. She showed little interaction with other demons and seems to be mostly disinterested in their presence. During the Lower Ranks Meeting, she calmly sat by and observed with the same stone-faced expression as the demons were all ruthlessly killed, almost paying them no attention and simply waiting for Muzan to give her another order. Similarly, in the Upper Ranks Meeting later on, she only speaks during two instances; answering Akaza's queries and rejecting Doma's invitation to be at his temple. Despite this, in her battle against Obanai Iguro and Mitsuri Kanroji, Nakime appeared to be very confident in her powers. She did not regard the threat the two posed on her, not even speaking to them and remaining unmoving as the two Hashira launched numerous attacks against her that would prove futile due to her vast and highly unorthodox powers. Ironically, she displayed the stereotypical murderous behavior of demons when she was a human. This was shown when she flew into a blind rage and murdered her husband after he lost her favorite kimono while gambling. In addition, after she successfully played her usual Biwa performances following her husband's death, Nakime had a habit of murdering people before performances, because she was anxious and her finger trembled which produced an effect on the strings of the biwa that the audience liked.

Nakime is a pale woman with a grayish complexion, who has sharp, blue-stained nails and notably dark pink lips which sharply contrasted the tone of her skin. She has glossy, hip-length hair of a black 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 dons a plain-loose black kimono with a white loose yuban underneath, secured with a striped pale brown-striped obi, white socks and no shoes or clogs. 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 daiji for |Shi}} engraved into its iris. The upper portion of her face was also revealed, and appeared to be a darker gray color than the rest of her pale skin with prominent veins surrounding her one eye. In addition, her hair would grow extensively and resembles roots on a nearby wall. File:Nakime colored profile.png|Nakime as Upper Four in the manga, revealing her single eye.

Overall Abilities
thumb|Nakime uses the Infinity Castle to fight back against Mitsuri Kanroji. Despite not displaying much in terms of fighting ability, as the holder of the fourth highest position in the Twelve Kizuki, Nakime is nonetheless an extremely powerful demon. She was capable of using her unorthodox Blood Demon Art to thwart the efforts of Obanai and Mitsuri at beheading her and stall the two Hashira for most of their battle, with neither of the two skilled combatants being able to so much as scratch her. Skilled Biwa Playing: Whilst she was human, Nakime was considerably skilled at playing the biwa. When psychologically tensed from murdering people, She was able to play highly beautiful music which draw praise for her music and playing, even when performing for a crowd who was previously displeased by her nervousness and dishevelled appearance. However, her skill seemingly did not translate as a demon, as her biwa playing as the keeper of the Infinity Castle is reduced to random, off-key plucks.
