~As a strange hobby, she personally tends to look at a person's teeth. It's never clear why she does to anyone.

Family: Muzan Kibutsuji (Father), Rei Kibutsuji (Stepmother), Muzan & Rei's daughter (Half-Sister)

Relationships:
-Muzan Kibutsuji: As her father, she takes a lot after him, personality wise, so she gets along with him on one hand, however, as she cares about other humans to avoid needlessly killing them and only go after criminals. She holds him in high respect, however, she doesn't quite have the same ideology as he does.
-Rei Kibutsuji: Being her stepmother, she was reluctant about knowing new family, however after spending some time with her, she grew to appreciate her and has a deeply caring side towards her.
-Muzan and Rei's Daughter: She has no bad relationship with her, but the opposite of it. She is very protective and kind towards her little half-sister. She often feels stressed while trying to be around her though because of fearing that she may do something that wouldn't be good for either of them, but she is still willing to be a good older half-sister for her.

Backstory: She was born in a village and was raised by Muzan as her father and she enjoyed being with her father. Unfortunately, as a ten year old child, she wandered off by getting distracted in wanting to pet a cat. This led to her being separated from her parents and for the longest time, she remained lost to the people of her village and family. She eventually began to travel places and then she managed to find her father again, being adopted into the ranks of being a co-leader of the Twelve Kizuki. After a long time, she left to expand her range away from her father so she wasn't reliant to others like she used to be. For this time, she would align with the Demon Slayers and she eventually met Sabito, Giyu, and Makomo. She befriended them and when Final Selection came, she was torn up about it when she saw their spirits and Giyu. After that, she would watch over others that entered the Final Selection.

Theme Song:

Name: Nakito Uzui
Age: 21
Height: 5'6"
Birthday: May 10th
Species: Human

Personality: quiet, caring, observant, intelligent, loyal, kind, understanding, serious, honest, playful, creative, protective, possessive

Likes: reading, drawing, training, hanging out with his friends
Dislikes: being repetitive, losing any of his friends, others disappearing out of nowhere, seeing women upset or scared

Habit: sleeping with a scroll over his face, getting lost easily
Niche: being dragged into something uncalled for
Fears: Seeing girls upset or scared, losing his brother

Ability: Blizzard Breath
Weapon: Sword

Other:
~He would end up occasionally wandering just to wander, so he gets lost often.
~Easily distracted, so this makes him aware of his surroundings as well.
~Always becomes exaggerated at his brother when he's nearby, which makes for a complicated relationship between him and his brother, as he respects his brother for his abilities, but his personality clashes with his on occasion.
~He is completely casual about if men were crying whether of joy or sadness, but if it comes from a woman, he will go into a full panic mode and try to find ways to comfort them, dropping anything else, making it a priority to make them happy again.

Family: Tengen Uzui (Brother), Makio (Sister-in-law), Suma (Sister-in-Law), Hinatsuru (Sister-in-law)

Relationships:
-Tengen Uzui: While Tengen often went for flashy aspects, Nakito often went for the casual aspects, which has led to many arguments between the two. However, he still has a high respect for his older brother's skills and fighting style. However, there are the times where they get along, which makes things difficult for others to defeat them when they use teamwork in their battles. He also attends events and holidays with his brother and his wives whenever he can, which seems to be most of the time, since he hurries through missions when it comes close to the time.
-Makio: Because of her blunt personality, he often purposely avoids angering her himself if he can help it, but is still willing to spar whether hand-to-hand or with their blades. He holds each of his brother's wives in high respect much as Tengen does, becoming like a cold shoulder when either of them are disrespected or held in low regard towards the one who held them in such low regards, but is casual towards those who haven't.
-Suma: He often ends up being the one to try and comfort her in a panic all of the time. Though he does this, he is aware of her strength in a fight even to the point of only sparring her when she has emotions to vent out that are needing to be vented.
-Hinatsuru: He holds her in very high respect and is unwilling to see her upset. He often looks to her if he needs advice on fighting or personal life matters. While he does hold each of the wives in such high respect, he would often stick close to his brother, at least within sight of him to ensure he will return home to his wives in concern for their feelings and his own.

Backstory: He grew up with his brother, Tengen and would be a slight troublemaker as a child. When his brother was offered the opportunity to become a Demon Slayer, he joined as well, but only went on his own training. When the Final Selection came, he partnered with Tengen through it and became a Demon Slayer. After becoming Demon Slayers, he also became his brother's partner for his time as a Demon Slayer.

Family: Inosuke Hashibira (Twin Brother)
Crush: Giyu Tomioka

Relationships:
Inosuke Hashibira: As her twin, he's the only one she would mostly trust and feel comfortable around. She is especially protective of him, despite knowing he can hold his own most of the time. So it'd be safe to say that these two have a very close relationship as twins.

Backstory: She grew up with Inosuke with their boar parent and she would always at least know where Inosuke was. She was eventually given the skin of a fox from Inosuke as a seventh birthday gift. She never got over some of her fears though, since she is especially scared of lightning and thunder, which has led Inosuke into yelling at the sky where the lightning and thunder came from as a way of both cheering hissister up and to challenge the sky to a fight, but mostly the latter.
