Summary
She was Muzan Kibutsuji's creation, but against his own design, she became something more.
Ayame Fujiwara was supposed to be a noblewoman, a wife, a vessel for heirs. Instead, sickness left her weak, childless, and forgotten — until Muzan Kibutsuji appeared in her garden, offering her strength at a terrible price. Now bound by his blood and haunted by her own longing, Ayame must navigate the dangerous spark between creator and creation… and the allure of a demon who shows her a tenderness no one else ever has.
(Notice: Chapters labeled "smut" can be read as a oneshot, if you wish to only read smuts. Or for those who don't like M-rated stories, you can just skip over these chapters.)

Summary
O dia estava gelado por causa da neve e dos ventos cortantes vindos ao norte.
A bestialidade no rosto daquele Oni, aquilo não era sua verdadeira forma.Passaram-se 96 anos após a morte de Muzan Kibutsuji e a dissolução da organização dos Caçadores de Demônios (conhecidos como Oni). Século 21, sendo representado pela tecnologia e o conhecimento para a inovação. Nesse amontoado de novidades, um oni secular se encontra perdido entre a necessidade da sobrevivência e a nostalgia mórbida de seu passado maligno e irregular.
Este é quase um Slice of Life de Kimetsu No Yaiba. Tive a ideia e resolvi escrevê-la por aqui.

Summary
What if Muzan has a much different past than the one in Cannon? Like, make him the definition of a sweet cinnamon roll that looks like he can kill you but won't because he's such a sweet cinnamon roll?
They say Muzan is evil, the demon progenitor who created demons that wreaked havoc since the Heian Era. A crazed monster that will destroy anything in its path. The very reason why the Demon Slaying Corps was established.
But, this Muzan has always been weak. Fragile, vulnerable. Some would even say beautiful, if not for the curse running through his veins. He is everything that Akane would want to protect, even at the cost of her life. When Akane first saw him, her first thought would be, 'pretty' and her second thought would be, a pure white soul amid black and purples that plague the whole estate.
She wants to protect that kind soul from being tainted. But then, that fucking doctor came claiming to be able to rid of the Ubuyashiki curse. The result? The purest soul she could see was dyed red. But first, she needs to distract these bastards so that Muzan could escape.Series

Summary
When you reincarnate you can usually expect to be some main Character or side character in the plot if you insert into an anime or whatever.
If your in inuyasha you might be a demon or something, it couldn't possibly that bad but unfortunately your not in inuyasha and your not born a demon; your made one and apparently it's not just any anime it's demon slayer.
So much for being a hypothetical not bad guy right. -
