Once More, with a Choice by SandsThatRVeryScarlet

Summary
The 1,000-year war against the Demon King had finally ended, thrusting humanity into a new era of peace. However, it was hard-won, with many devastating losses. The sacrifices were worth it in the end, but that didn’t mean they didn’t leave wounds that would take a lifetime to heal for the survivors.
Former demon - Kamado Nezuko - lamented being unable to properly meet many of the people from her memories before Muzan and his creations cruelly killed them. Still, she did her best to look forward to the future.
Sometimes, she would overhear talk of regrets and what-ifs. And each time, she would silently recall how she barely even had a choice in the time she lost after her humanity was stripped away from her. Could she have made a bigger difference if she could choose?
The opportunity to answer that question came with her waking up to find herself biting down on a familiar bamboo muzzle.
TLDR: Post-canon Nezuko gets thrown back in time to the start of the series with her consciousness and memories intact. She is determined to work towards a better future.
imo there's not enough Nezuko-centric time travel fix-its

Summary
A love story between the Wind Hashira's younger brother and the Sound Hashira's youngest sister. The latter is the ninth child of the Uzui clan and desires to know her worth, while the former couldn't use Breathing Forms in order for his older brother to recognize his existence. From their shared insecurities and standoffish natures, they become close to each other, even more than what anyone expected. This franchise belongs to Koyoharu Gotouge, so all characters, except my OCs, belong to them. Meanwhile, this fanfic is a remake of "I Like You, Scars and All" on Wattpad with the book cover being a work in progress until I could find an artist. You can submit fanart if you like and I'll give full credit.

Swearing, gore and/or body horror, physical abuse, manga spoilers, (implied) snu-snu, and SA. -

Summary
It’s pretty obvious that Obanai is not a people’s person.
Just one bad first impression is enough for him to immediately dislike someone and it’s pretty hard to change his feelings on something like that. He will be humble enough to admit however that it’s mostly his fault and rarely theirs. He’ll admit, if only to himself, that he’s the one who's hard to deal with. His personality has always been cold and harsh and he’s not above running his mouth against someone he thinks deserves it.
However, there are a select few he can endure being with.
Obanai’s…adopted family is a given. Mitsuri isn’t too much of a shocker either. What did surprise him was who else he'd find himself pleasantly enjoying the company of.
Shinazugawa Sanemi.
Not that he’d ever admit that to anyone. Including the wind breather himself.
Or
5 times Sanemi and Obanai deny their affection for each other from everyone, including themselves, and the one time they don't (Sorta).

Summary
Eyes filled with warmth and sincerity. The same unshakable kindness Muichiro had once clung to as if his life depended on it. That smile—so achingly familiar—spread across the boy’s face as he spoke, animated and earnest, his entire presence radiating the same light Muichiro had long believed he would never see again.
He had found him. Finally. He was here. In this world. Alive. Still the same eyes. Still the same kindness radiating from him.

Summary
In a cosmos where time and memory blur,
Three black holes yearn to alter the future's stir,
Unions of Keyblade Wielders forge ahead,
Through realms unseen, where few dare to tread,
Their keys unlock mysteries, old and untold,
Each twist in their journey daringly bold.But what of redemption for the starry sky?
Its cosmic lament, an unanswered 'why?'
In their quest, the paradoxical wielders may yet find,
A second chance for constellations misaligned.Eclipses falter, suns cease their descent,
As darkness meets light, a universe unbent.
With Sealed Memories and Apostles filling the void,
The edge of paradox is keenly deployed.Series

He should not have let himself get so poorly distracted.
