Nakime

Name: Nakime. Alias: The Biwa demon. Age: 113. Gender: Female. Pronouns: She/Her. Sexuality: Bisexual, preference for women. Species: Demon. Nationality: Japanese. Ethnicity: Japanese.

Personality: Nakime was a quiet and 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 her master, Muzan and obeys his orders without hesitation or question. Nakime is stoic and calm, she speaks very dull and straightforward when she does. Like all the other demons, She is extremely loyal to Muzan.

Appearance: Nakime is a pale woman with a grayish complexion, who has sharp, blue-stained nails and notably red lips which sharply contrasted the tone of her skin. She has shiny, hip-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 dons a plain black kimono with a muted white lining, 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 kanji for the word "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 pale skin with prominent veins surrounding her one eye.

Relatives: Unnamed Husband (Deceased).

The Twelve Kizuki: The Twelve Kizuki is an organization of the 12 strongest beings amongst demon-kind, second in strength and authority only to the Demon King himself, Muzan Kibutsuji. Each member of the Twelve Kizuki has received a large portion of Muzan's blood, greater than any other demon, thus exponentially increasing their power. As a testament to this, every member of the Twelve Kizuki can use Blood Demon Arts, supernatural powers and techniques manifested through their blood that only significantly powerful demons have access to. The Twelve Kizuki are divided into two groups, the six Upper Ranks numbered one through six, and the six Lower Ranks also numbered one through six. The number signifies their ranking among the Twelve Kizuki, determined by each member's level of strength, Upper Rank One being the strongest and Lower Rank Six being the weakest. The Lower Ranks have their numbers and ranks engraved only into one eye, whereas the Upper Ranks have their numbers in one eye and the kanji for "Upper Rank" in the other. While the exact relationships between the two groups are unclear, it is known that the Upper Ranks despise the Lower Ranks. The Upper Ranks each possesses a level of power that far surpasses that of the Lower Ranks; as proof of their strength, the strongest of the Demon Slayer Corps, the Hashira, have killed numerous Lower Ranks over the years, while the Upper Ranks have killed and eaten many Hashira. Kagaya Ubuyashiki states that it had been a hundred years since an Upper Rank has been killed following the defeat of Gyutaro and Daki. Furthermore, it has been remarked by Shinobu Kocho that the strength of an Upper Rank demon is, at least, comparable to three Hashira, although it should be noted that the capabilities of a Hashira vary from one to another, especially the ones who can manifest their Demon Slayer Mark to further augment their strength. While the Lower Ranks have been replaced countless times, the Upper Ranks did not change over 100 years.

Known UpperMoons: Kokushibo (UpperMoon 1), Douma (UpperMoon 2), Akaza (UpperMoon 3), Hantengu (UpperMoon 4), Nakime (Replacement Uppermoon 4), Gyokko (UpperMoon 5), Daki & Gyutaro Shabana (UpperMoon 6), Kaigaku (Replacement UpperMoon 6).

Backstory: In the past, Nakime was an obscure amateur biwa musician struggling to make ends meet. The man she married to was hopelessly addicted to gambling who squandered her earnings and savings while contributing nothing to improve their lives.

One night, she was scheduled to play her biwa at a particular stage but discovered that her husband stole her only kimono that she used for biwa performes and gambled it away. Enraged, Nakime murdered her husband using a hammer. Shortly after she killed her husband, Nakime realized that the appointed time to play was fast approaching, and she was forced to wear a worn-out, tattered kimono. The crowd did not appreciate her shabby looks and gave her disapproving looks. With the traumatic sensation of committing the murder for the first time still fresh in her mind, her hands shook in nervousness as she played her biwa.

But surprisingly, the sound coming from biwa as Nakime played with utmost tension, was so beautiful that her audience loved her performance and shouted for encore. Both her customers and the stage owner were pleased with the unexpected outcome and Nakime was paid handsomely. Since then, Nakime developed a disturbing habit of killing people before performing for large audiences. Every time the sound of her biwa was highly commended and her performance would receive extraordinarily positive feedback.

During a fateful day, when she had a routine appointment to perform at stage again, she randomly chose a new person to kill and the target happens to be Muzan. She tried to kill him but failed. Muzan was impressed with Nakime's searching skills and pleased with what she did, so he spared her life and offered to make her a demon. Nakime accepted his offer, became a demon and climbed the ranks quicky and became one of Muzan's top servants.

Fighting Style: Nakime's Blood Demon Art takes the form of an extra-dimensional space that houses a fortress of immense scale. As its owner, Nakime possesses absolute dominion over the space, being able to manipulate and alter it at will by simply strumming her biwa. In her fortress, there are countless rooms with seemingly endless variety, like an open room filled with giant pillars where the fight against Kokushibo took place; a small garden where the fight against Doma took place; a corridor leading to several other rooms where the fight against Akaza took place. Nakime sits at the center of the Infinity Castle, with the entire space being distorted around her.

Nakime has also displayed the ability to use her unorthodox Blood Demon Art for offensive purposes. She achieves this by shaping rooms into gigantic pillars and ramming it into her enemies to crush them. By binding and rooting her hair to a nearby wall inside the castle, she could control the castle's positioning as she likes: shifting and changing the positioning of various rooms and walls as if they were her own limbs. However, doing so presumably renders her immobile.

Nakime can also spawn portals to transport people outside her fortress or to anywhere within it in the form of tatami sliding doors. She can use her portals for offensive and defensive purposes as well, displayed when she created a portal to negate Mitsuri Kanroji's attack. One of her main duties was to act as a mode of transport for the other Upper Ranks when they are sent on missions and presumably assist Muzan in moving around the country undetected.

Timeline: This takes place in Japan's Taishō Period, around the 1920’s.
