Muzan's biggest fear is Yoriichi Tsugikuni, the legendary Demon Slayer who almost killed him and created Sun Breathing, and by extension, anyone wielding the power of the Sun (like Tanjiro), as it represents his near-defeat and reminds him of his mortality, despite his immortality as a demon. He also fears death itself, stemming from his own sickly childhood and near-death experiences before becoming a demon, driving his desperate desire for survival and power.
It is revealed that Muzan's true fear of dying and immense desire to live and survive was due to him being born "dead," where his heart would constantly stop in his mother's womb and was assumed stillborn until he fought to breathe before his cremation.
In Demon Slayer, Muzan is known as the Demon King because he is the strongest demon in existence and is immortal. However, a creature like this has only one weakness, i.e., sunlight.
Muzan has always been a rational character, but fans believe killing his doctor is the only time he regretted taking a life.
It was his dream for a thousand years, but Muzan isn't a good leader or good at strategizing either. The only reason he craved to be immune to the sunlight is because he was terrified of death. Without that fear, it's unclear what he would be like. He's arrogant, but that's a result of his cowardice.

While Muzan regretted the act, it was only because he realized that he couldn't walk in sunlight anymore as it would burn him into ashes, and if Muzan hadn't killed him, the doctor could have finished a finalized version of the cure, allowing Muzan to walk in sunlight without turning into ashes.
Before his physical death, Muzan, who was slightly crying tears after remembering Kagaya's words, was also able to transfer both his blood and his consciousness into Tanjiro's dying body, viewing the latter as the embodiment of Kagaya's final words and reviving him as the next Demon King who is immune to the sun and ...

Muzan's real scary gimmick isn't his power, but the fact that he can't die from a head cut-off. Even when the most powerful Hashira—Gyomei Himejima—does succeed in beheading him, Muzan absurdly regrows his head in an instant.
Rei ( 零 れい , Rei?) was a minor character in Demon Slayer: Kimetsu no Yaiba. She was a human wife of Muzan Kibutsuji, who had assumed a false identity.

Eventually obtaining the young demon's loyalty as a result of him "helping" him. After these events, Rui continued killing and devouring humans and was eventually awarded with the position of Lower Rank 5 among the Twelve Kizuki, where Rui soon became something of a favorite of Muzan's.
Muzan Kibutsuji may be the strongest demon ever created, but he's also the only one who's ever felt fear. That fear came from just one man—Yoriichi Tsugikuni, the original Demon Slayer legend. Their epic battle didn't just change Muzan—it changed everything in the world of Demon Slayer.
The only canonically LGBTQ+ character in Demon Slayer is Suma, one of Tengen Uzui's wives, who is confirmed to be bisexual and polyamorous in the series' databooks, showing affection for both men and women, including Tengen and her fellow wives, Makio and Hinatsuru.

Yes, Tanjiro lived past 25, marrying Kanao Tsuyuri, having children, and dying of old age, proving he was an exception to the 25-year lifespan curse of the Demon Slayer Mark, likely due to his Sun Breathing lineage and being the successor to Yoriichi Tsugikuni, notes ComingSoon.net and this YouTube video. While Muzan predicted his early death due to the mark, manga epilogues show Tanjiro surviving and living a full life, unlike other marked Demon Slayers like Giyu and Sanemi who died at 25, according to discussions on Reddit, Quora, and this Reddit post, confirms this Reddit post.
He deeply resented the thought of spending the rest of his life avoiding sunlight, and it was only then that he truly regretted killing the doctor before the treatment had been completed. Upon researching the contents of the doctor's medicine, Muzan discovered it contained a rare component: the Blue Spider Lily.
When Shinobu's death was released and announced by the crow, you could read Giyuu's thoughts easily as it was literally shown on his face. It was more heartbreaking for him to see probably the only pillar, who he considered a close friend die.
For instance, Muzan might have learned about the blue spider lily being in a household. Perhaps he believed that infiltrating as a woman would make his mission easier so he changed his appearance. Or maybe a demon slayer spotted him and after killing them he shifted into a female form to stay hidden and safe.
Underneath his masquerade of grace, Muzan smells distinctly of copper and a bitter, stinging stench that you could only describe as something dead or dying. You won't recognize it if you know what's good for you, even when the coppery scent ever-so-slightly bleeds through his usual fragrance.
Also the reason why Nezuko was already so powerful is because Muzan injected tons of blood in her body and the others in hopes of creating a demon that could conquer the sun.
