⚔️ The Pillars and Nyx

Giyu Tomioka: He distrusts Nyx because she is Muzan's daughter. However, he recognizes that she doesn't act like an ordinary demon and gradually begins to respect her. Shinobu Kocho: She is extremely curious about Nyx and her demon blood. She wants to discover the origin of her third eye, although she knows that getting too close could be dangerous. Kyojuro Rengoku: He tries to understand Nyx before judging her. He believes that being born Muzan's daughter doesn't necessarily determine who she is. Tengen Uzui: He considers Nyx extremely dangerous and, at the same time, fascinating. Her power and her mysterious third eye seem to him something worth observing. Mitsuri Kanroji: *At first, she is afraid of her, but she quickly discovers that Nyx can be sweet and protective. He ends up growing fond of her and trying to get closer to her.

• Muichiro Tokito: *He observes her with curiosity and constantly analyzes her movements. Nyx's third eye is one of the few things that truly piques his interest.

• Gyomei Himejima: *He immediately senses that Nyx possesses an extraordinary demonic presence. Although he doesn't completely trust her, he recognizes that there is something different about her.

• Sanemi Shinazugawa: At first, he hates her for being Muzan's daughter and is convinced that she will end up being a threat. However, over time, he begins to develop feelings for her. Sanemi is in love with Nyx *, although he flatly refuses to admit it and usually hides it behind arguments and provocations. He is especially bothered that other men, such as Inosuke or Kokushibo, have any kind of connection with her.

• Obanai Iguro: He deeply distrusts Nyx and watches her every move. Furthermore, she is not at all happy to discover that Sanemi is in love with a demon.

🐗 Inosuke — Nyx's ex

Inosuke is Nyx's ex , though their relationship was as chaotic as you'd expect from the two of them. Yes, to make the Demon Slayer + Nyx universe pretty complete, you can still add these groups: ### 🩸 Kamado Family Kie Kamado — Tanjiro and Nezuko's mother. Takeo, Hanako, Shigeru, and Rokuta — Tanjiro's siblings. Yoriichi Tsugikuni — extremely important due to his historical connection to Muzan. Michikatsu Tsugikuni — Kokushibo's past and a figure who might know secrets about Nyx. ### 🌿 Demon Slayers Kanao Tsuyuri — curious about Nyx and initially unsure whether to consider her an enemy. Genya Shinazugawa *— distrustful of her for being demon, especially because of her closeness to Sanemi.

• Aoi Kanzaki *— can't stand Nyx appearing in the Butterfly Mansion.
• Murata *— tries to stay completely away from any problems related to Nyx.

🧪 Nyx's Demon Allies

• Tamayo *— wants to study her blood and discover how her third eye works.
• Yushiro *— is extremely distrustful of her, although he eventually accepts that Nyx is not the same as Muzan.

👑 Nyx's Family

Here we can especially develop* Muzan *, because he is the one who can offer the most possibilities:

• Muzan *— Nyx's father and wants her to be his heir.
• Nyx may be the only creature that Muzan cannot completely control *.
• Muzan knows the true meaning of his third But he refuses to explain what will happen if Nyx fully opens it . Nyx could even be a threat to him if she ever decides to rebel.

🔥 Yoriichi

Yoriichi might have met Nyx in the past and be one of the few humans who saw her third eye open and survived . That would give him knowledge that even Kokushibo doesn't know. They met when Nyx hadn't yet revealed her full power, and he was captivated by her personality. ### 🌪️ Genya Shinazugawa — Sanemi's younger brother Genya Shinazugawa is Sanemi's younger brother and one of the Demon Slayers. Unlike his brother, Genya is more reserved, insecure, and has difficulty expressing his feelings. He is impulsive and can seem quite brusque, but deep down he loves Sanemi very much, even though their relationship is complicated. Genya possesses a very peculiar ability: he can consume parts of demons and temporarily gain certain demonic characteristics and abilities , making him an exceptional case among demon slayers. With Nyx, Genya initially maintains a distrustful relationship. He knows perfectly well that she is Muzan's daughter and is not at all pleased to discover that Sanemi is in love with her . In fact, Genya often thinks: "Of all the demons that exist... did he have to fall in love with her of all people?" Although he eventually accepts Nyx, he continues to keep a constant watch over her. And if Nyx opens her third eye, Genya is one of the first to be on guard. Inosuke was never afraid to provoke her and was one of the few who dared to challenge her directly. Nyx, for her part, found his wild personality amusing and ended up falling in love with him. The relationship ended, but there is still a rather evident tension between them . Inosuke continues to act as if he doesn't care, although he becomes especially aggressive when another demon gets too close to Nyx. And the funniest thing is that Rui considers Inosuke a terrible ex for her "mother" Nyx . ### 🌸 Tanjiro, Nezuko and Zenitsu Tanjiro Kamado: At first, he is very suspicious of Nyx because she is Muzan's daughter. However, upon getting to know her, he discovers that she is not an ordinary demon and that she retains emotions and a certain kindness. He tries to understand her instead of judging her, though he never lets his guard down when her third eye appears. Nezuko Kamado: Nyx ​​feels a special connection with Nezuko because they are both demons who retain a part of themselves. Nezuko doesn't seem to be afraid of her and often approaches her with curiosity. Nyx, in turn, protects Nezuko when other demons try to harm her. Zenitsu Agatsuma: He is terrified of Nyx, especially after discovering that she is Muzan's daughter. However, he also finds her beautiful when he sees her in her sweet and innocent appearance, causing him to go from being in love to being scared to death in a matter of seconds. Interestingly, his exceptional hearing allows him to notice when Nyx's third eye is about to open.

🌑 Lower Moons

Enmu: Lower Moon One. He is fascinated by Nyx and her ability to enter the minds of others. He loves watching her act with that sweet appearance while knowing that something much darker lurks beneath. Rokuro: Lower Moon Two. He respects Nyx's power and tries not to draw too much attention to himself. He knows that confronting her would be practically suicide. Wakuraba: Lower Moon Three. He is nervous and distrustful of Nyx. When he senses her nearby, he prefers to disappear before she can notice him. Mukago: Lower Moon Four. He is terrified of Nyx, especially her third eye. He avoids any situation that might anger her. Rui: Lower Moon Five. Nyx has a special relationship with him. Due to his way of thinking and his need to create a family, Nyx considers him practically her son , and Rui sees her as a maternal figure within his twisted idea of ​​family. Kamanue: The Lower Moon Six. He barely dares to speak in front of Nyx. He considers her presence too unsettling and fears that the third eye might reveal his thoughts. ### 🕷️ Rui — Nyx's "son" Nyx found Rui when he was still a young demon and ended up developing a strange bond with him. He is not her biological son , but Nyx treats him as if he were, and Rui came to consider her his mother. She tolerates his obsession with creating a family, although she doesn't approve of all his methods. When someone threatens Rui, however, the situation changes completely: no one touches her "son" without facing Nyx.

🌙 Upper Moons

Kokushibo: Upper Moon One. He is extremely serious, cold, and disciplined. Nyx awakens an unusual curiosity in him due to her nature and her third eye. Although he would never openly admit it, Nyx interests him more than he should , and he observes her every move. Doma: Upper Moon Two. He smiles constantly and finds Nyx's seemingly sweet personality fascinating. He loves to provoke her to try and discover what happens when she loses her temper. His curiosity about her third eye can easily become an obsession. Akaza: Upper Moon Three. She only respects those she considers strong. At first, she underestimates Nyx because of her appearance, but changes her mind upon discovering her true power. She cannot stand other demons trying to take advantage of her. Hantengu: Upper Moon Four. He is terrified of Nyx, especially when he hears about her third eye. He tries to stay away from her and uses his different emotions to escape if he feels threatened. Gyokko: Upper Moon Five. He is obsessed with Nyx's appearance and wants to turn her into one of his "masterpieces." However, Nyx finds his experiments repulsive and has no patience with him. Gyutaro and Daki: Upper Moon Six. Daki is somewhat envious of Nyx for her beauty and the attention she receives. Gyutaro, on the other hand, immediately distrusts her and suspects she is much more dangerous than she appears.

YESSS 😭. We're including Nyx in Kimetsu no Yaiba (Demon Slayer) as one of the most dangerous creatures connected to Muzan.### 🌙 Nyx — Muzan's Daughter Nyx is the daughter of Muzan Kibutsuji, created from his own blood and endowed with an abnormal amount of demonic power. At first glance, Nyx seems sweet, calm, and even harmless : she speaks softly, smiles innocently, and rarely shows aggression. But that appearance is precisely what makes her so dangerous. Nyx possesses a third eye hidden on her forehead. It usually remains closed, and no one knows exactly what she is capable of when she opens it. Demons who have witnessed her true form prefer not to speak of it. When Nyx's third eye opens, her behavior changes completely. Her presence becomes terrifying, her power increases brutally, and she can perceive things no ordinary demon should be able to see. Even Muzan avoids provoking her when that eye is open. What's most unsettling is that Nyx doesn't need to be angry to use it. She can be smiling sweetly... and simply open the eye. And then, it's best not to know what happens next.
