Summary
But what if Giyuu completely changed? Sabito was not actually his closest friend. During the Final Selection, Sabito tried to set a trap and kill Giyuu—but in the end, he was the one who died. Bearing the pain of this betrayal, the only thing Giyuu could do was to keep moving forward.
He joined the Demon Slayer Corps and proved his skills. Well, it seemed that the Hashira needed a Water Hashira. And the one Kagaya had in mind was none other than Tomioka Giyuu.
(Of course, Giyuu’s story holds more than what meets the eye.)

Summary
"I gave my life to you. Even knowing you could never love me the way I love you. Still, I’d do it again. In some other life, if the stars are kinder, I hope you’ll feel what I feel. Just once. That would be enough.” — Uzui (Agatsuma) Zenitsu
When Emperor Tengen issued the decree—a command for all unmarried omegas to present themselves for royal selection—Zenitsu obeyed, as all good citizens must.
He did not expect to fall in love with the Emperor first.

Summary
What if Tanjiro met Zenitsu, Inosuke, Genya and Kanao at the Final Selection? How will it change the story? This fanfic is all about their friendship and how a meet up changed the course of the original Demon Slayer Canon.
But, first few chapters are pretty bad in my opinion, but if you manage to stick through! I hope you’ll see my improvements in writing!

Summary
In a dystopian Japan subjugated by the ruthless rule of demons under the emperor Kibutsuji Muzan, the Mazoku Era has transformed the archipelago into a nightmare of iron and blood. Cities, choked by toxic fumes and oppressive laws, are divided between the opulent districts of demonic elites and the squalid slums where humans toil to survive. In a world where hope seems extinguished, a flicker of resistance endures, carried by broken but determined souls.
Muichirō and Yuichirō Tokitō, twin brothers scarred by tragedy, struggle to survive in the underbelly of Kuragari-shita. Their lives, defined by grueling labor, hunger, and fear, are upended when they come into possession of a dangerous secret—a legacy from a mysterious warrior that could alter humanity’s fate.
Amid the intrigues at the pinnacle of Edo’s Tower, the gratuitous massacres and abuse of demons, this story probes the resilience of the human spirit in a world where survival demands sacrifice. Muichirō and Yuichirō must choose between submission or reigniting the flame of a free future.

Summary
a demon slayer fic
They did it. They defeated the demons; they defeated Muzan.
But at what cost?
Amidst the Ubuyashiki mansion, there is a stark silence; an emptiness that does not suffice the loss. Of course, all the Hashira and slayers put their lives on the line to emerge victorious, and they would do it again–
But what if they could do it again? What if they had the opportunity to turn back the clocks, even for a short while, and prevent the evitable?
Giyu and Sanemi, despite their differences, can agree on one thing: the battle sacrificed much. Too much. Their collective dwindled from nine to two– thus, when a letter came by to suggest such an absurdity, the two Hashira couldn’t help but pursue it.
the hashira (+extras) "stuck in a room" (ubuyashiki mansion) for as long as they need to stop hating each other

Summary
How did things become so horrible that demons and demon slayers had no choice but to band together to prevent human extinction?
It came out of nowhere — and it was killing everyone. Civilians. Hashira. Even the Upper Moons. The Aijoubyou virus spared no one. It didn’t care what you were. Only who you loved.Muzan and Kagaya named it together — Aijoubyou. Love Sickness. Because that’s how it spread: not through wounds, not through bites, but through affection. Through trust.
They both believed it could be Japan’s version of the Black Death. A plague born from the heart.Who in God’s name would believe that the moment someone started showing you warmth — gentleness, kindness, affection — that would be the sign you needed to kill them and burn the corpse?
And how do you kill something that turns love into its weapon?

Sanemi Shinazugawa doesn’t trust her. And yet, every mission, every clash... every stolen glance begins to crack that hatred he clings to. As war looms and demons shift in the shadows, Mazikeen must choose: bury her past, or become the monster she was forged to be.

Summary
Now Sanemi was really pissed off. One moment, he was the laughingstock of all his fellow Hashira. Now this ice-faced pretty boy comes marching in out of nowhere and everyone is cooing over him like a freshly hatched baby bird? What gives? What the hell was going on?
“He’s the new Hashira, idiot.” Obanai answered. “And you’re talking out loud. You’ll scare the ‘baby bird.’”
Giyuu looked like he wanted to disappear into the ground.
The Hashira – eight of the most intelligent, hardworking, and distinguished students that made up the student council. On a technicality, Giyuu is now supposed to be one of them. He doesn’t feel very deserving of the title, but at least everyone has been kind and welcoming. Well, almost everyone.
Sanemi excelled at school and he was damn proud of it. Being the only support system in a house with an absentee father and too many siblings, it was a miracle that Sanemi could pass his classes let alone score high enough to be a Hashira. Everyone on the student council was nothing short of exceptional. Well, almost everyone.
