Summary
Sorry but this starts really slowly
"You will be the one I kill at the end of the day." The Hashira started as he stared down at the Uppermoon who looked back at him smiling holding up a silver ring his blood inside of it.
"Let's see how long you can resist me dear. I promise this ring will find it's way onto your lovely finger~"Also I will try to post every 2 weeks if I don't post a new chapter, It means I am working on my personal OG series or an extra long chapter! ☺️

Summary
The night was thick with the hiss of steam and the weight of silence.
The Mugen Train loomed before them, lanterns casting its metallic body in flickering amber light. Passengers rushed to board, voices buzzing like a swarm, but for Giyuu Tomioka, the world had narrowed to the man walking beside him.
Kokushibou’s steps were unhurried, quiet, his human guise flawless—no one suspected the truth. No one else could feel the storm hidden within his presence.
But Giyuu knew. And knowing was unbearable.
A Hashira must never fall in love with a demon.
Even more so with an Upper Moon.The words repeated in his head like a law carved into stone. Yet his chest burned with something that defied that law, something fragile, treacherous, alive.

Summary
Almost on cue that familiar pressure weighed down on him.
He didn’t have to look to know who was behind him.
He stood, picking up his sword, he held it out in front of him as he turned to where he knew the upper rank was.Those six red and yellow eyes starred at him.
He maintained his composure despite having fear eat away at him.
“You again.”
He said, just loud enough to be heard.The upper moon tilted his head, looking at Giyu curiously.
“Why are you so obsessed with me?”
The Pillar said coldly.
The demon’s eyes widened and his face went a pale red.
He blinked a few times, his face returning to a near white.—————————————————————————

Summary
Giyuu doesn’t really know how it happened, but he’s somehow found himself very dependent on a demon. Uppermoon 1, to be exact.
She’s found himself head over heels for this demon. This—this creature he’s supposed to hate, supposed to exterminate. But yet, this demon—Kokushibo, has found every way to make Giyuu fall more for him.
But he knows what this means for her, for both of them. If anyone finds out, they’re both done for.
That risk becomes a lot bigger and a lot harder to hide when she ends up carrying that demon’s child.
OR
Kokugiyuu fic that centers around Giyuu’s pregnancy ! There will be a 2nd fic after this one finishes that’s primarily about them raising the baby n stuff.
Summary may change in the future

Summary
It was surprisingly dark tonight, with only a few stars and the moon present to chase away the darkness of the night.
Michikatsu briefly closed his eyes, feeling the cold gush of wind hitting his skin.
Ever since quitting the ranks of Upper Moons almost more than 100 years ago after a careful deliberation of his desire to change course, Michikatsu had dedicated his time in blending back into society, bearing his human appearance and his human name
Defecting was easy, but it wasn't hard to lay low either.
It was a bit comical, the former second strongest demon who used to strike fear on demons and humans alike, who had killed and claimed thousands of lives in his centuries of living, now merely goes around small towns he had burrowed himself into, helping countless people with their daily concerns and labor.
Little did he know, the entire trajectory of his life would be thrown in a different direction once he meets the current Water Pillar.

Summary
Kokushibou had seen wars, plagues, betrayals, the rise and fall of generations.
But nothing — absolutely nothing — had prepared him for Muichirou.
Not Muzan, not the corps, not even the awkwardness of being openly in a relationship with the Water Hashira, Giyuu Tomioka, while half the Hashira made suggestive jokes about how “a demon must be thirsty for more than just blood.”
Kokushibou ignored all of that.
There was, however, a single obstacle to their bliss.One thing, one tiny, innocent-looking, wide-eyed descendant that he could not overcome.
Tokitou Muichirou.

Summary
Kokushibou was running when he heard it: the scream.
Men and women were running through the streets, clutching children, tripping over one another in desperate terror. Smoke curled from overturned lanterns. And there—amid the chaos—stood Giyuu.
Or what was left of him.
The transformation, to Kokushibou’s eyes, was grotesquely fast.
Giyuu’s form trembled, hunched, his breath erratic. A horn splitting skin in a spray of blood, claws curving into weapons, eyes that burn crimson glowed faintly. In an instant, the man he loved was a demon.
Kokushibou’s six eyes widened, and for the first time in centuries, true fear coiled in his chest

Summary
Giyu delivered a swift and powerful kick to his chest causing him to stumble back, another harsh kick to his stomach forced him to take another step back, a loose root tripped him up and caused him to tumble, his back hitting a tree as he fell.
Giyu walked up to him, placing a foot just above the demon’s abdomen, keeping him in place and the tip of his sword pressed against his neck, although Kokushibou could easily get out of this situation, he didn’t exactly want to.
His view was quite stunning.
Giyu ground his heel down, still awaiting an answer.
Kokushibou’s eyes sharpened slightly when he realised that it was not his abdomen his human was stepping on. -

Summary
He was baffled by the man's masked reaction. How could someone get so set off just seeing a pair of earrings?
Unless… he was a...
No. That couldn't be. He had a demon slayer mark. He had a sword. He was in Giyuu's estate. He was friends with Giyuu.
The smell got stronger.

Or, Tanjiro checks up on Giyuu, only to find him relaxing with another man. They talk, before Tanjiro's suspicions are raised against the other man, who Giyuu says is his friend. All hints lead to him being a demon, but how could that be possible? It was unthinkable!
Meanwhile, Giyuu and his "husband", Kokushibo, have a soft conversation with each other after Tanjiro leaves. Almost entirely oblivious to his inner turmoil. -
