Summary
"Tanjuro," Zenitsu gasped, and whatever he meant, the words were lost in a groan of pleasure that was swallowed up by the night around them. He clung to his shoulders, panting and hiding his face in the crook of his neck.
Ahh, too embarrassing! Tanjirou, have mercy on his poor heart, he won't be able to take it if you keep touching him like that - as if he were precious, as if he were loved.
And Zenitsu was, he knew he was, he just had difficulty understanding that someone like him could be loved by someone like Tanjiuro.

Summary
Because of his overly developed hearing, Zenitsu hides in one of the rooms of the brothel where Mr. Tengen sent him with the others.
He couldn't have foreseen that the room would soon be occupied, nor that two men would enter.
(He didn't even expect to react that way, nor to think about what it would be like to be in their place with Tanjirou.)

Summary
"Do you want to leave?" Tanjirou asked, half asleep.
"Mhm…"
Zenitsu froze as Tanjirou's lips brushed the sensitive skin beneath his ear. The contact sent shivers down his spine, conflicting violently with the throbbing in his temples. " Tanjirou, wait—" he stammered, voice raspy and strained. "Last night… it was the wine. A mistake. I didn’t—"
Tanjirou pulled back abruptly, his drowsy warmth replaced by sudden stillness. Those crimson eyes, usually brimming with gentle certainty, now held a vulnerable, almost wounded softness. "A mistake?" he murmured, the words barely audible. His thumb traced Zenitsu's jawline, tentative and searching. "Do you regret it?"

Summary
When one lost soul encounters the easily frightened boy. The world around her is filled in black and white; her view in life is the horrors of bloodshed past.
Emotions, a foreign reaction stirs within her when that boy, his hair resembling the vibrant sunset of the morning light covers her palm with his large ones.
Truly a rarity if one demon and a human found comfort in one another through time they teach each other a lesson.
And that is the beauty of accepting each other’s difference.
[Zenitsu x OC]

We lost the battle but this is war! by TheFicEraReal

Summary
In a world where a man has taken countless lives without punishment or interruption, do you really think luck would have favored Tanjiro and his friends?
No, but it didn't favor Muzan either. The battle was a huge loss for both sides, one more damaged than the other, of course.
Genya wasn't hit by Kokushibo's attack and actually survived the fight; Sanemi survived but was no longer capable of continuing the fight due to major injuries; Giyu died trying to protect Nezuko from one of Muzan's final, desperate attacks.
And Muzan himself? He survived without being punished, without paying for what he had done, without anything... Now the demon corps needs to recover to attack again, under Kiriya's command and the survivors' guidance in the fierce battle. Will they succeed this time, or will Muzan continue his reign of terror?
(I know, I know, the worst summary.)

Zenitsu becoming Uzui's son? HELL YEAH!
_________
What if Tengen didn't retire? He still has his eye, just slightly worse vision. His hand is still mostly intact, a few fingers gone.
_________
Just Tengen being Zenitsus dad and helping him through insecurities. May or may not punch kaigaku. -
