Summary
“What—”
Giyuu barely gets the word out before Sanemi yanks him sideways, dragging him through the nearest door. The moment it clicks shut behind them, Sanemi is shoving Giyuu up against the wall, hands fisting in the fabric of his uniform, mouth crashing against his.
Giyuu stiffens, a surprised noise catching in his throat, but it lasts only a second. Then he’s melting into Sanemi’s touch, his hands reaching out to clutch at the front of Sanemi’s haori as he kisses him back just as fiercely.
Then the closet door swings open.
~~~
OR: The Hashira find out about Sanemi and Giyuu's relationship in various ways.

Silver. Around Shinazugawa’s finger. His ring finger, to be precise. It glinted in the light, a bewildering beacon.
Shinazugawa Sanemi, the wrath demon incarnate, was married.
And no one knew who it was.

Summary
While the racing world was arguing over front-wing endplates and potential budget cap breaches, a user named anon6238126 posted a thread on r/formula1. Usually, the subreddit was a fortress of technical data or gossip, but this post didn't contain a single graph.
It was a scan of a document from a local ward office in a quiet district of Japan. The paper was slightly yellowed at the edges, the kind of mundane administrative record that should have been buried in a filing cabinet forever. But the names written in elegant, official script were unmistakable.
r/formula1 Posted by u/anon6238126 • 2 hours ago
Found this while archiving old Japanese municipal records. Is this who I think it is?
I’m not into F1, but I kept hearing these names because my best friend is obsessed with it. My friend says these two are rivals who can't stand each other on the track? If that’s true, then why is there a marriage certificate for a Sanemi Shinazugawa and a Giyuu Tomioka?
Looks like they've been married for seven years. Am I crazy or is this a massive coincidence?

“I’m not sick,” Giyuu admits.
Sanemi scoffs and rolls his eyes, clearly not pleased with this. “Well, that’s bullshit because–”
“Sanemi, I’m not sick,” Giyuu cuts Sanemi off. “I’m pregnant.”
Sanemi goes silent at that.
or, an accidental pregnancy turns Giyuu's world upside down, all while the fight against Muzan and the demons rages on.

Summary
Shinazugawa Sanemi and Tomioka Giyuu will put Tengen into an early grave, he’s sure of it. Those two were put on this planet to do just that, Tengen swears. He imagines he must’ve done something awful in his last life to deserve punishment like this.
Now, the average rational person will ask why this would be the case, and well, the answer is quite simple. It’s because Sanemi and Giyuu are the most oblivious people on the planet, no, the entire universe.
This thing between them has been going on for a year, a whole year, an entire nine months plus three more. People have a freaking child in that timespan. It’s been a whole year of watching Sanemi and Giyuu act like they’re not together when they’re essentially together. It’s maddening, and Tengen is losing sleep over this, wondering when things will fall into place for those idiots.
or, Tengen is determined to get his stupid, oblivious coworkers together, no matter the cost.

Summary
Tengen Uzui, the Sound Hashira, knew the mission in the Red Light District would be hard, so when Tanjiro suggested calling a friend of his, Uzui didn’t refuse it. He expected that friend of Tanjiro to be a low-level Kisatsutai member or something like that, but not a fellow Hashira.
Since it was too late to withdraw, why not disguise their guest to the mission as well?

Summary
"Oh," Izuna said -- delicately, while studiously reading his folder, "I'm afraid we need someone with a ... strong personality for Naohime."
"Why's that?" Hashirama replied, just as painfully polite.
The daimyo's mediator kept watching them and scratching little pointy words in his notebook.
"Because if your man doesn't prove that he's dangerous and has the personality to use it on her if she pushes him, it's going to turn abusive," Madara drawled.
Hashirama stared at him for a blank second. The daimyo's envoy stopped writing; even his stone-faced Aburame bodyguard arched her eyebrows over her darkened spectacles.
Tobirama stretched out across the table without another word to take back one of the folders Izuna had spread around him.
--
The daimyo is over the whole Uchiha/Senju war. They're going to become one people if they know what's good for them.
Madara hates it enough without having to marry a woman too.

Summary
It was a day like any other when Tobirama looked at Madara and thought: I love this man.
The revelation was sudden—except for all the ways in which it wasn’t. He’d been falling for a while now, slow and easy and inevitable, and some part of him had known that.
Determined to keep and be kept, Tobirama embarked on a slow, subtle courtship.
It went well… until Madara clued in.
Then it went fantastically.

Summary
After a mission alongside Sanemi Shinazugawa, Giyuu Tomioka returns with her uniform torn and blood-stained, the aftermath of battle still clinging to her like a second skin. A Kakushi quickly presents a replacement—only for it to be grotesquely altered into something impractical and revealing, more suited for display than survival.
OR
An AU where the same Kakushi who offered Mitsuri, Shinobu, Kanao and Aoi... revealing uniforms, also offered one to Giyuu.

Summary
“Giyuu— did something happen— what’s—”
Giyuu slowly turned her head toward him.
Eyes calm.
Voice steady.“I’m pregnant.”
Sanemi froze mid-step, mid-breath, mid-life. He looked like he had just taken a full-force hit from Upper Moon One.
“…Come again?”
Giyuu slowly stood up, made her way towards him, and blinked.
“I’m pregnant.”
*
OR the au where
Sanemi and Giyuu were careful.
Ridiculously careful.
So when Giyuu is suddenly, quietly pregnant, the two spend the next several days desperately trying to hide it — and failing in spectacular, escalating disasters.
Unfortunately, the Hashira are nosy, Tanjirou is honest, Zenitsu is dramatic, and Inosuke is Inosuke.

why are you yelling at me? by Anonymous

Summary
“Oi.”
Sanemi’s rough voice cut through the air. He stepped directly in front of her, scarred face scowling.
“You didn’t say a damn thing the entire time. Not a word. You always do this—sittin’ there like you’re better than the rest of us.”
Giyuu blinked at him, silent.
Sanemi’s irritation spiked. His voice lowered but grew sharper, the kind that cut to the bone.
“You think you’re special ‘cause of that whole ‘I’m not like you’ crap you once spat? Hah? You’ve got zero social skills, your dumb little ponytail looks like a crow’s nest, and don’t get me started on that annoying stare you give everyone.”
His voice rose with each insult, harsh and unrelenting.
And then—
Her eyes shimmered, lips trembling. She looked like she was about to break.
In the softest, broken whisper:
“...why are you yelling at me?”

More dodges, more counters. Tomioka was fast. Too fast. Sanemi’s fist finally came close, about to land straight to Tomioka’s jaw—
“STOP!”
A shrill yell split the air. Tanjirou came barreling across the grounds, arms flailing, face red with panic.
“WHY ARE YOU PUNCHING A WOMAN, SHINAZUGAWA-SAN?!”
The world froze.
Sanemi’s fist hovered an inch from Tomioka’s face.
His brain blanked. “HUH?!” he shouted, turning so fast his neck cracked.
Stoic as always, Tomioka simply lowered her guard, expression unreadable. Not a single word of denial.
