Before becoming an Upper Moon, Nakime had long dark hair, her bangs partially obscuring her face. After obtaining the rank of Upper Moon Four, Nakime's now perfers having her hair parted from each other revealing her face, showing that she only possess a single cyclops like pink colored eye in the middle of her face with the Kanji of Four is engraved into her irises to symbolize her Rank as one of the Upper Moons.
Nakime is a mysterious yet cold biwa player who displays little emotion. She doesn't speak unless necessary, and when she does, she is often straightforward and blunt, making her responses as short as possible.
When Akaza asks her where Muzan is, she replies straightforwardly that he has not yet arrived. She is also questioned as to where Upper Moon One is, to which she replies (after Akaza's and Doma's bout) that he has always been there; he was the first to arrive.
At the end of the meeting, Nakime plays her biwa again to separate the Upper Moons and bluntly refuses Doma's offer, cutting him off by sending him back to his temple.
Nakime, now the new Upper Moon Four replacing Hantengu, is shown near Muzan. Using small eyeball familiars, she has been tracking down the Demon Slayers and determining their locations and hideout. Expressing her honor at Muzan's compliment for her rapid growth, she uses her technique to locate Kagaya Ubuyashiki.
When the Demon Slaying Corps arrive at Ubuyashiki's mansion to try and stop Muzan, they are all transported into the Dimensional Infinity Fortress and separated from one another.
Abilities and Powers

- Fortress Manipulation - Nakime possess the ability to manipulate and control a seemingly infinite inter-dimensional fortress by playing her Biwa, being capable of bringing anyone she desires into the fortress and is capable of creating entrances and exits anywhere she desires, and by binding and rooting her hair to a nearby wall inside the fortress she can control the Fortress's positioning as she likes, shifting and changing the positioning of various rooms and walls as she pleases,However doing this will render her Immobile.
- Eye Detachment - Later upon obtaining the Rank of Upper Moon Four and presumably receiving more blood from Muzan, she has now displayed the new ability to create and detached several Eyeballs from her body allowing her to spy on others from long range, with this new ability it was possible for her to successfully find and locate the locations of nearly all members of the Demon Hunters Corps all across Japan and locate the hidden mansion of Kagaya Ubuyashiki, who had gone to extreme lengths to hide its location from even the Highest ranking members of the Demon Slayer Corps.
- Nakime has many similarities to the Former Lower Moon Six, Kyogai, both uses a Blood Demon Arts that allows them to freely manipulate a specific structure at will, both uses a musical instrument to use their individual techniques and both have been given their epithets based on these instruments.
