Summary
Tanjirou rasped with a strained voice. “The other Hashira and Genya—they’re close,” He swallowed hard as his fingers trembled to find the hilt of his blade. “And it smells like they’re fighting an Upper Moon.”
Giyuu’s expression darkened. “Which way?”
Tanjirou pointed toward the opposing corridor, where the shadows seemed to pool thicker into a suffocating pit of darkness.
...OR...
Another way the battle against Upper Rank One could've unfolded.

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?

Summary
Muzan stared at the vicious twists of flesh that made up the disturbing form of whatever Tanjirou decided to depict on the paper. The thing looked like it came from the deepest pits of hell, its face contorted in a derisive sneer. The misshapen limbs reminded him of what happened in the Dungeon, and the entire piece was framed by unsettling looking mounds (?) of tangled (?) limbs (?). Though, looking closely at the particular shapes, he thought he saw-
-”Tanjirou”
-”Mmh?”
-”Is this Douma?”
The human beamed at him with the brightness of a thousand suns (ouch). He felt a little smug that he guessed right. Tanjirou could give the author of the Mainichi puzzles and guessing games a run for his money.
-”You know, I really think you’ve captured his true nature. This is exactly how I see the real thing. It’s as if you distilled everything that makes him him.”
Or the AU where, after meeting a suspiciously familiar looking child, Muzan decides that exposure therapy is a good thing and maybe kidnaps said child (oops)

Summary
Within the work of Kimetsu no Yaiba, the war between Slayers and Demons is almost impossible to avoid, even when a few worlds of this universe are lucky to end it quickly. Eventually, it did come to an end with the final generation of Hashira and Upper moons, with Tanjiro Kamado and Nezuko Kamado becoming pivotal pieces in the conflict. But what would happen if the roles within the war were swapped, all except the Kamado siblings? Can they still end the Demon progenitor of this world? How would the Corps and Demons change under different leaders that grew in a different environment? Well… How about we see for ourselves?

Summary
At first, Kyojuro Rengoku was on board with the whole “execute Tanjiro Kamado and his demon sister” plan. After all, he was a Hashira, one who had grown up following the morals that demons were all inherently evil and harboured no good intentions.
To hear that Nezuko Kamado had never eaten a human was… unheard of, to him.
…Now he wasn’t so sure.
|~|
Senjuro and Shinjuro become demons, and Kyojuro embarks on a journey with them to find someone that can help. But once again, miscommunication punches them in the gut, and they end up dealing with far more than they bargained for.

Summary
Kokushibou was nothing more than a grieving demon, a man whose heart is filled with sorrow and guilt. However, after 500 years of conflicting emotions, of inner turmoil, he finally finds solace. Unfortunately, the one to give him such peace only one person could manage is Tanjirou Kamado, who-due to being the legacy of Yoriichi- was ripped by said demon from his family.
Nezuko was so cold, so lonely...her family was gone, her brother was kidnapped and she had not a single person to help her...but that only motivated her to bring her brother back from the clutches of demons, to where he rightfully belongs, with her and her friends, with the Demon Slayers.
This is my first fic so if you spot any errors, let me know in the comments!
