Summary
After a tragic accident, a young boy named Tsuki finds himself in the dark world of demons — not as a mere human, but as one of them. Despite his new form, he clings to his humanity and resists the thirst for blood. Living in constant fear of being discovered by Muzan himself or his loyal Moons, Tsuki searches for a way to break free from the curse.
In silence, he observes the stories that shape destinies — until he meets the mysterious Lady Tamayo and decides to confront his own fear. But when he learns that the future depends on the young Kamado Tanjiro, he realizes that his struggle is not only about survival, but also about hope for a new beginning.
Can Tsuki resist the darkness within him and protect those whose future matters most? Or will his demonic nature consume him before he can fulfill his purpose?
A story about the strength of will, the secrets of demons, and the fragile line between light and shadow. 🌙 -

Summary
Kaya and Kaizu Miyasato, two normal half Canadian, half Japanese siblings find themselves transported to a world Kaizu knew little of, but Kaya knew quite well: Demon Slayer. However, there was a bigger problem than the mystery of how they'd ended up there; The two had been separated from each other with no way of knowing where the other was, or even if they were alive.
Kaizu found himself in the company of Tanjiro and Nezuko, whom he at least knew a little about due to reading the first manga. Kaya ended up stuck with Obanai Iguro as his Tsuguko, under Shinobu's suggestion. Both siblings had one goal: find the other. They didn't particularly care for the demons, they just wanted the company of someone they knew from their lives beforehand.
Will the duo be able to survive a world full of demons and find their way back to each other, or are they doomed to meet the same fate as so many others...

Summary
Mitsuri Kanroji is the Goddess of Love. Always has been always will be. This Goddess of Love loves nothing more than her job-seeing people fall in love, stay in love. She really could never get sick of that word (though, her good friend Sanemi could.) But when an unforseen mistake threatens her role as Goddess, she must go down to earth to fix everything, before it's too late.
Mitsuri has always been a genius when it comes to love, this should be no problem. Falling in love herself however-
That's a different story.

Summary
Rengoku Douma has the worst luck.
First, he was born into a cult and instated as an object of worship, nothing more than a plaything for the adults around him. Then, his parents tragically died in a murder-suicide. If that wasn't enough, after 14 years of living a relatively normal life with the loving family who adopted him, he was turned into a blood-thirsty monster only capable of consuming human flesh.
He tries to remain under the radar, he really does. He has an office job, and everything. He still lives with his adopted family, despite being 25. Sure, Douma needs blood donations to survive, but life could be worse.
And, soon enough, it does get worse.
Douma is caught hunched over a deceased girl by one of his coworkers, Shinobu Kocho. There's only one catch—the girl was dead when Douma found her, but Shinobu is convinced that he's the perpetrator of the crime. Shinobu agrees not to tell the police that she thinks he did it on one condition; Douma must help her solve the mystery of the disappearances of young girls and women in their Tokyo neighborhood, a phenomenon that the police in their area seem to be ignoring.
He reluctantly agrees.

Summary
To live and die as a hashira was one of the greatest honors. Even though she couldn’t decapitate a demon’s head, Shinobu still persevered and became someone her sister could be proud of. She even managed to form an intimate bond with one of her fellow hashira during her great achievement.
But that bond led to Shinobu facing a situation she could’ve never dreamed possible, and now the insect hashira was left facing a decision that either let her focus on revenge or focus on living the life her sister prayed she could have.

What if Tanjiro met Zenitsu, Inosuke, Genya and Kanao at the Final Selection? How will it change the story? This fanfic is all about their friendship and how a meet up changed the course of the original Demon Slayer Canon.
But, first few chapters are pretty bad in my opinion, but if you manage to stick through! I hope you’ll see my improvements in writing!

Summary
Three years have passed since the Flame Hashira’s light was extinguished.
At the Rengoku estate, Akari—the Flame of Compassion—has built a quiet life for herself and her young twins, her days filled with children's laughter, the whisper of hooves, and the ghosts of her past. Though the Corps continues its fight against Muzan’s demons, she has remained apart, guarding what remains of her family and the fire her husband left behind.
When Sanemi Shinazugawa, the Wind Hashira, returns to her life, their shared grief and relentless spirits begin to intertwine. What begins as duty and uneasy friendship grows into something neither expected—something that tests the boundaries of loyalty, loss, and love reborn.
As new battles loom and the shadows of the final war gather, Akari must reconcile her duty to protect those who cannot protect themselves the call of her and her late husband's heart—and discover that even flame, when carried by the wind, can burn anew.

Summary
Tsukiyo escapes a childhood shaped by an assassin clan and is saved by a retired Shadow Hashira who teaches her how to live when all she’s ever known is killing. Her past leaves her bold, unsettling, and irresistibly honest—someone who barges straight into people’s comfort zones with a grin and a philosophy that life should never be lived timidly.
She wields a scythe instead of a sword, a weapon as unconventional as she is, and cuts her way through demons while documenting every adventure like a promise to herself. She falls quietly, hopelessly for Giyu, knowing the feeling won’t be returned, but she refuses to bury it; loving without regret is part of the vow she made when she chose her own path.

Dicen que en la nieve nada puede florecer.
Pero yo, Sakura Saitō, aprendí lo contrario. Tras perderlo todo, la espada fue lo único que me quedó, y el deber, mi única forma de seguir respirando.
En mi ascenso como Hashira Estrella, descubrí que incluso el hielo más antiguo puede derretirse… y que a veces, dos almas quebradas pueden reconocerse en el silencio.

Summary
Supervisor of the herpetology lab at Wisteria University, Obanai puts out an ad for an assistant, and he's not prepared for the pink whirlwind that comes calling. She's sweet, so sweet that it makes his teeth hurt, but her availability is terrible! She cleans part time for the kendo club on campus, and can't fill in on Tuesdays because of a late night class. Not to mention that she doesn't have any of the applicable skills outlined in the advertisement. But, Obanai hires her anyway, not that anyone else applied, and Mitsuri Kanroji becomes an assistant snake handler under him.
Obanai finds himself falling for her. Everything feels so simple, like puzzle pieces coming together, and he's never felt anything quite like it before. However, nothing is ever as simple as it should be, and Obanai gets the wrong idea when he sees her with the Kendo captain, Kyoujurou. Things get even worse when Mitsuri confides in Obanai that someone keeps stealing her underwear out of the dorm laundry machines. All Obanai wants is for her to happy, healthy, and safe--and he'll be damned if anyone is going to get in his way.
