Dampness (潮湿) by soysauce456

Summary
Original Author's Summary:
Two people accustomed to disguising their true feelings and keeping silent are trapped by a demon within a barrier that forces them to tell the truth.
Within their own lives of relentless downpour, each catches a glimpse of the dampness the other has walked through as well.
—Set in the original canon timeline but in a version where no one dies. (My heart's simply too fragile to endure reliving all those deaths in my own fanfiction.)

Summary
Even with Yushiro’s demonic blood protection seal in place, the Upper Rank Four had managed to track down the Insect Hashira, Shinobu.
Fortunately unfortunate, when her biwa resonated violently that morning, Shinobu did not end up in the Infinity Castle—but in a completely different dimension.
And, by a stroke of luck, her best friend Mitsuri Kanroji was still the same as always… more or less.

Don't Get Weird Ideas About the Neighbor's Little Sister by soysauce456

Summary
Original Author's Summary:
A modern school AU (senpai–kouhai dynamic) about a childhood friend pair: a boy who appears cold on the outside but is warm-hearted underneath and a tsundere girl with a prickly, short-tempered personality.
Their personalities are still fairly close to their canon selves. This idea came from seeing a fellow fan comment under a post about a collaboration involving the shrines associated with Giyuu and Shinobu's birthplaces, wondering what the two of them would be like if they had grown up as childhood friends. For some reason, my terrible taste immediately made me want to see a scenario where Shinobu is pressured by her family into calling Giyuu "big brother" (what awful tastes I have).
—If there's one thing that must be remembered from that youth that felt both slow and hurried, it's that each of them was like the sun to the other. He melted the hard shell around her heart, and she broke into the dark, forbidden depths of his inner world.

Summary
Kanae was gone. Shinobu hadn't just lost her sister; the corps had lost a hashira.
On paper, Shinobu was worthy of the title. Behind closed doors, she was crumbling beneath the weight of responsibility.
"Insect Hashira Shinobu Kocho. What a joke." Shinobu, and perhaps everyone else, thought.

Summary
Shinobu's plan is almost complete.
She's prepared herself to let go of everything she has tried to cover up. The hallucinations of her older sister, hiding her binge eating from the Butterfly Estate Residents, and her complicated feelings toward a certain blue eyed comrade of hers. But when she starts to let her walls fall, she can't decide whether it's worth staying with those she has left, or finishing her suicide plan to meet her sister again.
Shinobu is struggling to get by from day to day, whether she has another episode of trying to gain weight by stuffing herself, injecting wisteria into her body, or keeping on a plastered smile and demeanor she has worked so hard to keep up.Tags will be updated as fic progresses

Summary
Original Author's Summary:
"The story has reached this point and yet nothing has ever truly changed. Even so, she tells the divine messenger that she no longer has any unfinished regrets. For regret was always the most hidden, yet also the most brilliant color within that irretrievable love."
Kochou Shinobu carries her memories into a new life, reincarnated as a shrine maiden. Once again, time comes to a halt at the age of eighteen. But this time, it's not because she dies young—it's because she no longer ages.
To break free from this curse-like immortality, she must find her family as they have been reincarnated in the mortal world and fulfill one lingering regret that remains unfinished...

Summary
Shinobu Kocho has always been an extraordinary person. Sarcasm pours out of her, and her thoughts sparkle with unintentional mischief. She experiences situations ranging from crazy pranks involving violations of dozens of dogmas and laws to real tragedy. Perhaps Giyu Tomioka is not the quiet, arrogant jerk that many people think he is. After all, it was he who became the lover of such an unusual girl. This fanfiction will drag you through her whole life, you will kind of suffer, but you will love it.

Summary
Original Author's Summary:
Tomioka Giyuu, a judicial police officer under the Tokyo Metropolitan Police Department, is assigned an elderly pharmaceutical expert in his seventies as his partner during an operation. However, he accidentally catches a glimpse of the man's true face and discovers that his partner is actually a strikingly beautiful young woman.
Unfortunately, this leads his partner to declare that she intends to kill him, because no one besides him has ever seen her real appearance. At the same time, Giyuu finds himself wanting to uncover the truth behind why this young woman disguises herself as an old man in the first place...
A story set in Taishō-era Japan, but in a world without demons. The tone is relatively lighthearted. The setting revolves around crime and organized criminal groups. While the structure of the police force is partially based on the historical system of the time, some elements have been altered for the sake of the story and should not be taken as historically accurate. Most of the main cast comes from the Water Breathing group and there are also hints of a romantic subplot between Sabito and Makomo.

Summary
Original Author's Summary:
Tomioka Giyuu x Kochou Shinobu
Setting: Fictional Religious AU
Warning: Extremely OOC (Out of Character). Please approach this as an adult work with a slightly wordy/verbose narrative style."In stark contrast to those silent, freezing gazes, vigorous vitality overflowed from their two constantly moving bodies, as if symbolizing how they, in their mortal forms, were defying the meaningless eternity above their heads."

Summary
She vanished without a trace — and the Corps whispered her name like a ghost.
Shinobu Kocho, once a prodigy, now lives hidden among humans, crafting poisons capable of killing demons without a blade. A quiet vengeance.
A death wish disguised as purpose.But when Giyu Tomioka finds her again, everything she buried begins to surface — grief, rage, tenderness she can’t afford. He wants to save her.
A demon wants to keep her.
And Shinobu… isn’t sure she wants either.As love, loyalty and obsession tighten around her like threads of silk, one truth becomes impossible to ignore:
Not all demons hunger for flesh —
and not every hero longs to live. -

Summary
This is an authorized repost. The original author is Yaotai (瑶台). If you like it, please support the author on their original platform. This is for sharing purposes only.
Original Author's Notes:A Children's Day (June 1st) celebratory fic and of course you have to make children on Children's Day! The title pretty much sums up the entire story.
This is a modern Giyushino AU featuring their domestic life as a young married couple living together. After all, it's hard to imagine how they would celebrate Children's Day in the Taisho era 😌
🆘 Warning: A child appears at the end (Tomioka June 1st / the Children's Day baby is born!).
✅ Female on top / Cowgirl
✅ Fingering
✅ Belly pressing/massaging (gently caressing...)
✅ Internal ejaculation / creampie (Please do not imitate in real life. She actually gets pregnant this time!)Apologies for any OOC! This piece surprisingly has a lovely, slice-of-life domestic vibe. I'm using it to practice writing longer pieces in the future 😌, attempting to blend in more emotional/romantic scenes 💞
