Zenitsu Agatsuma believed he was born unlucky. The alarms that rang just before his exams, the lightning storms that always seemed to follow him, and the way his own heart raced itself into exhaustion whenever he tried to be brave.
Then came Senjuro Rengoku—transfer student, art club member, and younger brother of the school’s most enthusiastic History Teacher.

It's always about how the moon relies on the sun, how the moon requires the sun to shine.
Well what if it was the opposite?
What if the sun wasn't as bright as we may think?
If the sun burnt out, could it ever be ablaze ever again?

Summary
While others still used their fire to burn, Senjuro used his to warm.
A series of loosely-connected one-shots and two-shots about Senjuro Rengoku: too soft for the world, too precious to be left unguarded, and too beloved to be shared.
His father and brother might be all flame and wrath—but when it comes to Senjuro, they become something else entirely: feral, tender, and utterly possessive.
Canon? Left at the door.
Domestic. Angsty. Fluffy. Sometimes violent. Always protective.

“Could you stop with that?” he snapped. Senjuro flinched, confused.

Senjuro runs into the Mist Hashira while visiting the recovering Tanjiro and Genya after their return from the swordsmith village. He is caught off guard when Tokito then decides that they are friends. What could he, a failed tsuguko, possibly have in common with the most talented prodigy in the ranks of the Hashira?

Summary
Zenitsu was depressed, his brain kept telling him that he was useless and coward.
It didn’t matter If he felt happy sometimes, because the feeling would be sucked in the void and would not stay with him. Even if his eyes lightened for a moment, it was only temporary.
He could of course try his hardest to stay above the surface, but it was exhausting. It was like swimming, but you couldn’t come out from the water. The water would sooner or later exhaust the person swimming on it, and the person would start sinking.Senjurou knew that he had to do something to prevent himself from the same fate that Zenitsu already had. He had seen what it can do to people around him, and he didn’t want to lose this battle.

Nefelibata // Demon Slayer: Kimetsu no Yaiba Various x Reader by vibetopia

Summary
nefelibata - (n) lit. "cloud walker;" one who lives in the clouds of their own imagination or dreams, or one who does not obey the conventions of society, literature, or art.
A story in which an average kid from our world with a history of rather unfortunate luck gets isekai'd and trapped in the world of Demon Slayer. Though, instead of being 2014 Wattpad Y/N aesthetic, they're a mentally ill gen z-er.
Or, a platonic rewrite of my old KNY story because I really dislike how it looks. (For the THIRD time in a row...) This time, the reader will (hopefully) be more realistic! And the author won't get locked out of his account again!!

Summary
The bed that surrounds the fallen Hashira is soft, though it doesn't hold the warmth he desperately needs. It does not bring the comfort of a father. It does not support him the way only his sibling could.
He does not long for the hands of his mother.— (This is a lie that can't last, for a child will always long for the warm arms of a mother.)
He fears that he will never be the same.
