Izuku is training to inherit One For All, the quirk of the Number One hero. One day, he finds several strangers struggling on the beach, changing the course of his life forever.OR:
An attempt at a Warframe/MHA crossover fic that spiraled out of control in a fit of sleep deprivation-induced insanity.

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.

If only I could've been stronger like you guys...

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
In a different timeline, Makomo became the water Hashira, this won't make Giyuu or Sabito return to life, but at least she can honor their memories. In another timeline Sabito spared the demon girl after witnessing the bravery of her older brother, he sees a little of his younger self in him, at least he hopes the boy can protect his sister, unlike him, who couldn't save Giyuu during the final selection. Giyuu doesn't know what is happening; one moment he's slicing Lower Five's neck, another moment he faces two slayers who hold an uncanny resemblance to his late friends.

Zenitsu's distastrous high-school (and love) life by Baron_Bunny

Summary
[Kimetsu Academy-ish AU (with my own twists)]
For the overly emotional and sensitive Zenitsu who absolutely sucks at making friends, going into high-school is possibly one of the scariest things to happen to him. Fortunately, his friends (aka, the kamaboko squad) came to him, instead of him to them, and he has them and his family every step of the way into this unfamiliar territory.
And, for someone as obsessed with love as Zenitsu is, he really is a fool for not being able to see that his two closest friends like him.

Summary
The Demon Corps had done it-the impossible. The endless war ended with the Demon King's death beneath the piercing rays of the rising sun. Yet victory demanded the ultimate price... none lived to see it.
The nightmare was over.
But not for one man.A swordsman blessed by lightning rose from the ashes. No longer the trembling coward, he vowed to become the wall that would defy time itself-to shield the ones he loved and strike terror into demons like the wrathful thunder of the heavens.
Zenitsu Agatsuma awakens in a world both achingly familiar and impossibly distant. Fate has given him a second chance-or perhaps a cruel jest. Haunted by battles yet to come and faces he could not save, he walks a fragile path where even the smallest change could unravel destiny. And as shadows gather once more, a single question remains: can he rewrite the future, or has fate already chosen his end?
MAJOR SPOILER FOR THE DEMON SLAYER MANGA!!!

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.

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.
