Summary
The moment everything changed was the moment Douma felt something within him. His chest was not hollow - his heart was not still... not anymore. Something in him stirred and he felt a small twinge of his lungs, filling him with foreign warmth. Suddenly, the world was vibrant, and at the center of it was her. She was called Kotoha, a young woman with dark hair, deep beautiful eyes, and a truly lilting voice that seemed to soothe the heavens in its softness.
The demon was transfixed. The baby in her arms suddenly didn't seem so annoying in its cooing and her smile didn't seem fake as he assumed most were.
The day everything changed was the day Douma truly smiled for the first time.
WARNING: Contains death, gore, trauma, blood, foul language, angst, and subtle references to SA
WARNING: Also contains a reformed Douma, a redemption for Akaza (with some romance included for the poor man as well as some closure with his wife), Inosuke gets a family, Kotoha gets to be happy, Daki and Gyutaro get to heal, Genya and Sanemi WILL communicate eventually, Uzui is vibin', Kanae gets to L I V E, Muzan is TICKED, Kokushibo is LONELY, and life is good... mostly.
Also, Kotoha adopts... everyone. Just... everyone. -

Summary
At the age of six, Reika Hashibira received a divine blessing, a power unseen in hundreds of years. A power that could save or damn the lives of those around her. A power that placed her in the middle of the conflict between demons and humans. Captured by this power, kept alive by its usefulness, she must endure horrors and tragedies, growing up under the care of Douma, the Upper Moon 2, who, after destroying Reika's family, insists on calling himself her "father." Between the sacred and the profane, between emotions and apathy, she will struggle to maintain her sanity, but in the process will she lose her humanity, becoming more like the monsters who raised her?

Summary
Thousands of years ago, a pact was struck between gods and mortals. In exchange for rain, harvest, and peace, the Kanroji family would sacrifice their firstborn son to the Land of Demons—every generation, without fail.
It was the price of prosperity.
It was the will of the Storm Gods.
It was never questioned.Until now.
Mitsuri Kanroji was never meant to be a warrior. She was too strong, too strange, too much. But when she learns the truth about her brother’s fate, she makes a choice no daughter ever has: to take his place, to cross the forbidden gate, and to face the gods themselves.
Even if it means unraveling the ancient pact.
Even if it means facing death.
Even if it means becoming legend. -

Summary
It all started because of Muzan’s orders. Or at least that’s what Kokushibo tells himself.
Because ending up trapped in Douma’s orbit—where boundaries blur and hierarchy crumbles under casual touches and empty smiles—would be a misfortune for any demon. Especially for Kokushibo, who believed himself above such things.
But in truth, Upper Moon One had already been defeated long before he realized it.
Then, in the dark, Douma whispered:
“So… do you want to stay one more day?”
Yes. Kokushibo has lost completely.

Summary
"Humans are so pitiful," Douma lamented, dangling yet another luxurious offering in his long thin fingers. Toying with the hauntingly expensive pearls until they were crushed underneath his superior strength. "They live and die like the common worm, yet convince themselves that their lives have meaning."
"Isn't that silly?"
Inosuke, being a mere two years old and incapable of saying more than 'Douma', 'milk' and 'dada', just stared as he continued his tirade. Giggling as he watched the demon grind the pretty necklace into fine dust, before lifting his palm to smear it into the pile of broken prayers and disrespect.
"Ah-ah-ah, Inosuke"- Douma grinned, not bothering to contain his bark of laughter at the toddler's angry pout - "Wouldn't want to get filthy, would we, my little flower?"
Inosuke could only stick his tongue out in response.
-----
Douma lived his life thinking he was incapable of having emotions. Yet what if instead of being unable to feel emotions, they were simply suppressed due to his traumatic lifestyle? What if something, or someone, could allow these emotions to come to light?
