Summary
In the Hidden Kurobane Residence, laughter echoed as Aiyaka and Itsuki played in the yard, chasing animals without a care. From the veranda, their parents watched in silence.
Hoshika clutched a crimson ribbon, her warm voice breaking. “Do you think they’ll understand?”
Akihiro’s sharp gaze stayed on the children, his tone steady, pragmatic. “We must be strong… for them. Aiyaka may understand, but not Itsuki.”
Tears welled in Hoshika’s eyes. “My only regret… is not seeing them grow.”
He pulled her close, voice low. “I know. But we must have faith—in them, in our allies.”
Hoshika brushed her tears away, forcing a gentle smile. “Kids…”
They turned eagerly. “Yes, Mother?”
Akihiro beckoned them, stoic and calm. “Come here. It’s time for a family meeting.”
The siblings hurried over, unaware.
They didn’t know this would be the last time their family sat together. The last time they would hear their parents’ voices. The last time their world would feel whole.

Summary
Getting a second chance is something many people wish for and something that I got. If only I’d been more specific about where I ended up, at the rate this world is going, I’m going to need a third chance soon. Good thing that I've got the Grimm Reaper looking out for me.

Summary
A world and body not your own.
Demon slayer, a simple enjoyment in your last life. Yet here you are. Is there a chance to save all your favorites?
Life and death are around every corner, and you become the one factor unaccounted for. You know the future of every major fight.
Do you have time for romance, time to get to know the people around you that you adored in your world?
Your knowledge needs to be kept hidden, except, what if you forget to account for the Demon King himself? When you become the common face in every major failure, always waiting for an exact moment, like you know it’s going to happen, you can’t expect Muzan not to take notice.A target rises easily on your back, but not an order to kill you.
Will you survive and save your beloved characters turned friends, or fall into Muzan’s grasp dooming them?At the moment, there is no dedicated love interest, all characters over 18 are considered possible love interests. (Demons with child-like appearances or who act like a child/turned as a child are not considered) Reader will be referred to as she/her and female anatomy will be mentioned. This is an Isekai type story.

The Scarlet Performer: Slayer in Shadows by JustYourFriend
Fandoms: 鬼滅の刃 | Demon Slayer: Kimetsu no Yaiba (Anime), 鬼滅の刃 | Demon Slayer: Kimetsu no Yaiba (Manga)

Summary
This story is based on an AU (Alternate Universe) idea where Tanjiro Kamado becomes a demon — but not the kind you expect. Instead of losing his humanity, he hides it behind charm, grace, and terrifying control.
In this version, Tanjiro is a renowned performer whose elegant dance style is secretly rooted in Sun Breathing. After a tragic twist involving Muzan, he becomes a hidden demon who joins the Demon Slayer Corps to fight from within — blending beauty, deception, and deadly power.
This is my personal take on a more complex, theatrical, and morally gray Tanjiro — a “charming predator” who walks the line between monster and savior.
It’s not a strict storyline, more like a flexible AU sandbox. Anyone is welcome to use or remix this idea — just credit and share where it came from. I’d love to see your version.

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

Summary
As the Snow Hashira, Tsuki is revered for her elegance in battle, feared for her silence, and envied for the power hidden beneath her stillness. But no one—not even she—expected the fire of Kyojuro Rengoku to melt her winter.
This is a story told in breathing forms. Of a girl who never feared demons but feared becoming one. Of a man who always smiled toward the future, even when she was stuck in the past.
A fight against fate. A promise before dawn.
And the hunt for the demon who destroyed her family… still unfinished.

Summary
Just a handful of stories featuring my OC, the Frost Hashira, and our favorite Flame Hashira. They loosely follow the story, but are mostly made-up scenarios that would fit well into the plot in my opinion.
It's an AU where everyone survives because I refuse to write anything sad, and they definitely deserve a happy ending with everything they've been through.
They can be read as one-shots or as several chapters linked together. I'll post as ideas come to me.
