Summary
In a ruined world where the undead roam freely, Giyuu Tomioka somehow lives untouched. Zombies ignore him like he’s invisible — they don’t bite, they don’t chase, they just shuffle past him as if he doesn’t exist. He’s made peace with it, quietly scavenging groceries from abandoned convenience stores, feeding stray cats, and watching the sunset from ruined rooftops.
That is… until he meets Sanemi Shinazugawa — loud, scrappy, and very much edible.
OR
Zombie Apocalypse AU where giyuu is immune to zombies and sanemi's stress levels and high blood pressure break world records while trying to keep both of them (mostly giyuu) safe.

Summary
What if the Hero course students were sent back in time to learn lessons they have struggled to learn, things to help them become better Hero’s from the Hashira's, Ages are altered for the Hashira, just made them younger
Or
When UA sends its top students into the past to learn, no one expects the one to break first will be the teacher: a fifteen-year-old war-torn boy named Sanemi Shinazugawa.
part of a dying world, Sanemi is forced to train happy, hopeful children to survive horrors he's lived through. By the time they realize he's not a hardened warrior but a child who's lost everything, it's almost too late.Now comatose and clinging to life in the modern world, Sanemi becomes the center of a storm: media outrage, student rebellion, and the fall of Nezu. While the world begins to ask the question it should have from the start—what happens when the one you called a weapon turns out to be just a boy?
A slow-burning tale of grief, healing, stuffed animals, and learning to live in a world that’s finally soft enough to hold you.

Summary
Like any other organization, the Demon Slayer Corps were no stranger to rumours. To no one's surprise, the kakushi were always the first to know of anything and everything. However, there was one rumour that circulated for a long time, one that every kakushi, new and old, knew. Rumours about a Miracle Selection. Participants who did live past their first few months as demon slayers didn’t rise too high in the ranks. Many performed pretty average and remained in the low to middle ranks. All but one achieved something impressive.
What exactly set him apart?

Summary
Two students fall in battle—and wake up wrong.
In the aftermath of a training accident at UA, something unseen slips through the cracks. Bakugo falls silent. Todoroki won’t stop speaking. Their classmates think it’s shock.
It isn’t.
They are not the ones who woke up.
Pulled from a world long gone, two warriors find themselves reborn in unfamiliar bodies, carrying voices that don’t belong to them and powers they don’t understand. One clings to a voice he thought he lost forever. The other refuses to hear his at all.
Trapped in a future that has no place for them, they must navigate a society built on strange abilities, unfamiliar rules, and relationships that don’t fit the lives they left behind.
But the longer they pretend—
the more obvious it becomes.Someone is going to notice.
And when they do—
there will be nowhere left to hide. -

Summary
Perhaps Muzan’s greatest mistake was turning Tanjiro into a demon, and Tanjiro’s greatest mistake might turn out to be listening to the voice in his head.
Yet he listened to those honeyed words and used his blood demon art to do the unthinkable. Reversing time…not just for himself. But for everyone. Giving them all a second chance.
Everyone who lived and died during the final battle against Muzan gets sent back ten years into the past.
The Kamado family lives, as Tanjiro and Nezuko both have their memories. Giyuu gets to save his sister. Sanemi and Genya save their mother. Gyomei saves the orphan children in his care. Shinobu gets to save her parents and sister. Muichiro saves his brother and parents. Tengen kills his father and convinces his siblings to join the demon slayers, his wives remember everything too. Zenitsu trains with his ‘gramps’ again. Inosuke leaves his mountain sooner. Kanao runs away from her wicked life and heads to the Butterfly Estate, being welcomed by the Flower Hashira who trained the Kochou sisters. Obanai escapes and kills the snake demon his family worships. Mitsuri joins the corps early. And Kagaya will do everything he can to ensure their safety.

Summary
In a world of Soulmate Strings, Giyuu’s remains lifeless.
Although it’s not he cares. He’s got enough on his plate already. At the University he’s constantly ridiculed or fetishized for being transgender. He’s had already expected it if he’s completely honest, but it hurt more knowing that his older brother was one of the many that made his life miserable.
Yes the same Sabito who used to tuck him in and protect him from imaginary monsters.
That same Sabito is the one who blames him for their horrible father walking out on them.While Giyuu’s life is falling apart, Sanemi seems to be living the life. Popular. A girlfriend. An amazing group of friends.
He always adds to the pain because why would he care? It doesn’t affect him.One day Giyuu is walking, when he sees a child run onto the road. Giyuu sees a man who is intoxicated and not slowing down, he makes a fateful decision. He jumps.
Sanemi realizes his soulmate far too late
Two years later Sanemi wakes up and has been transported back in time when giyuu was still alive. His friends and Giyuu’s friends were also sent back too.
It’s a second chance but it’s their final one.Bookmarked by Dat_ao3user

Summary
Tomioka Giyuu has been de-aged to age 12. (Beginning of Season 1)
The Hashira did not think that they would be tasked with taking care of a hyperactive ADHD & Dyslexic 12 year old who went by the name of Percy Jackson.
Just what exactly happened to Giyuu to make him the way he is now?
This is an AU, so story line obviously won't be the same as the books or anime. I have yet to read the manga, so what I do know is from the anime & edits/videos.
