You’re The Best Thing I Never Knew I Needed by rosehearts0_0

Summary
“What do you think of them?”
He’d anticipated it, and yet his mind couldn’t give an honestly concrete answer. He hardly knows the kids, for crying out loud - how should he know (translation: how could he give a preconceived opinion on almost-strangers out loud without sounding like an absolute asshole?!)?
And for a brief moment, Kyōjurō’s odd expression flashes in his mind.
…He settles for the default, in all the obnoxious spunk he had to offer.
“What else? They’re unflashy.”
In every sense of the word.

Summary
"That doesn't hurt at all. Do you know why, Zenitsu?"
"Shut your mouth!"Kaigaku sneered.
"Because I'm not real."After the Final Battle, after countless millenia, Kibutsuji Muzan, the bane of the world, was finally eradicated. It was a monumental occasion. And yet, why was it that Zenitsu couldn't find it in himself to feel happy?
And, why are Tanjirou and Inosuke so hopelessly in love with him?

Summary
The last thing Giyū saw was the horrible creature known as Muzan crawling away to another part of their quickly crumbling world, taking the hashira who could still fight with him, and the bodies of those who no longer couldn't, behind him. Giyū was the latter, trying to stand up even through the sea of blood at his feet. He was dying.
Why was this happening? Wasn't the slayer mark supposed to boost his survival?
Turns out, it did. Maybe a little too well.
Fate had once again chosen the wrong person to save, Giyū thought, back in his thirteen year old body, staring at his dead childhood friend right in the face. Tanjiro would have been so much better at time travel.

Summary
Tanjirou is turning 25, and the Demon Slayer Mark curse is supposedly coming for him. His family is determined to protect him at all costs.
On the front lines of the “Tanjirou Protection Squad” are: Inosuke, his fiercely devoted husband, whose love language swings wildly between roaring death threats at him for daring to die and startlingly tender acts of care. Zenitsu, resident fearmonger, armed with questionable holy objects and endless, theatrical laments about Tanjirou’s hypothetical death. And Nezuko, normally the sensible one, who is slowly realizing that her husband’s paranoia is alarmingly contagious.
What follows is a year of well-meaning drama and chaos. Through it all, Tanjirou is just trying to survive… not the curse, but his loved ones’ relentless flood of grief, devotion, and love.

Summary
“Look carefully at his breathing,” She said, “Don’t be afraid to get close.”
It was almost unnoticeable at first, but if he listened, he could hear water. Like he was at a beach with waves calmly washing ashore. It was calm and peaceful. He swore he could smell the salt.
The nurse almost laughed at them. “Yeah, that's kinda the reaction we had. Never seen a quirk like it."
A MHA and Demon Slayer crossover.
