Summary

Unfortunately for him, the universe has a sense of humor...and assigns him the one roommate he’s secretly been in love with for five years.
Now he’s stuck living with a sunshine omega who thinks they’re already best friends, insists they eat meals together and looks way, WAY too good fresh out of the pool.
Giyu is hiding a dark secret.
Rengoku is a delighted cinnamon roll.
Slow burn romance ensues, but so does a fire that threatens to burn them both to ash. -

Summary
He didn’t remember when he had gotten close to the kids, it just happened. Suddenly, he was “Giyuu-san” (or the derogatory use of “Dad” or "Mom" used by Inosuke when he says anything parental-like) to a group of teenagers.
He glanced to his left, where Muichiro was staring off into space, walking beside him. He had spent the night at the water estate again, after showing up, dazed and confused, in the rain. Not that Giyuu minded, he had a few Yukatas and such saved, as well as ready room for him, or the other kids, in his home that he had bought after realizing that having Tanjiro meant attracting whoever else was with Tanjiro. He also wondered how Tanjiro had so many friends, and managed to attract them like flies. But he did enjoy having the kids over, they were a lot to deal with, all in all, but they were sort of nice, they made his Estate livelier and just… better.
OR: Giyuu Tomioka slowly finds himself becoming a parent for the kids around him, and they slowly accumulate at his lovely estate hidden behind the waterfall, because I live for found family and them.
Terms for Giyu might differ at times because I needed to have a Genderqueer character)

Summary
“I get it now… that means… you’re a Sun Breathing user, aren’t you?!” Shinjuro demanded angrily, and Tanjiro had to bite back the sassy reply he wanted to give because, yes, he was, but at this age he was only barely figuring out his kagura as a breathing form.
“What is that supposed to mean?” Tanjiro questioned instead, bracing himself as Shinjuro shot forward to grab him. This was going to hurt, but he didn’t care. Tanjiro would never, in any life, let this bastard talk badly about Kyoujuro or strike Senjuro without returning the favor. Tanjiro bit back a cry of pain when Shinjuro slammed him into the dirt, his leg and arm crying out in protest at the impact for all that he stayed silent.
“Father, stop! Don’t do this!” Senjuro cried out as he tried in vain to pull the grip off Tanjiro’s only functioning arm. “Stop this! Can’t you see he’s in pain!”
“Keep your mouth shut, boy!” Tanjiro couldn’t see it happen, but he could hear it when Shinjuro struck his son and got a front row seat to the red blooming on his face when Senjuro’s body fell to the ground in front of him.

Summary
"Oh shit- Come on kids! It was an accident! Uncle Tengen didn't mean it!"
A deep, menacing noise filled the air. The self-proclaimed 'Uncle Tengen' barely had any time to curse himself before Aoi and Naho were safely on the ground, and he found himself pinned to the rocky path.
"I'm going to give you ten seconds," their savior, who Tanjiro recognized as his and his siblings' Mama, spat. "That should be plenty of time to think of an explanation for this, Uzui."
Tanjiro sucked in a breath. He knew he recognized the man. He was one of the Hashira at the trial. He voted to kill Nezuko!
Uzui put on a fearful smile. "Come on, Tomioka! I messed up, I get it! I didn't mean to hurt your babies! I just need female Corps Members for a mission and- ACK!"
The Water Hashira tightened his grip on the alpha's throat. "So you chose kidnapping? Do you know what Shinobu would say?"
OR: Giyuu joined the Kamaboko Squad as Uzui Tengen takes them to the Entertainment District. What could go wrong? (Spoilers: Everything!)

Summary
Despite the tense stiffness in his soul, he made two long strides towards their new comrade—who didn’t stop looking at him with a look Giyuu didn’t want to fixate on—extending his hand to shake his as a tender smile appeared on him, only to be surprised when it wasn’t returned yet denied as the water hashira lowered his abdomen in a deep bow nearly bending him in half. Back straight as a board, hands enveloped together behind him, and tied up hair falling over his shoulder
He rose back up, same motion as before, never extending his hand to accept the others.
He looked at him in the eyes, lowering his chin in respect
“Tomioka Giyuu”

Summary
“Akaza,” Muzan croons, nails digging into his shoulders.
The name… he recognizes it as his own, but it doesn’t slot right in his mind. The syllables don’t fit on his tongue. He doesn’t perk to it because it sounds like him, he raises his head because he simply must.
OR
Hakuji rejects humanity. Akaza realizes, then forgets. Kyojuro thinks Tanjiro’s kindness is infectious, and sees something that the demon doesn’t remember.

Summary
“You blinked as your vision somehow only then adjusted to seeing the now rising moon. Then looking over at the person that had defended you.
It was a man. He also had a seemingly kind voice but it was noticeable that he actually had feeling behind it. You couldn’t tell his exact appearance but there was one thing you could see.
His eyes.
It was as if they held the sun in them.”
A Rengoku Kyojuro x Reader expect it’s like Howl’s Moving Castle.

Summary
It didn’t last for long.
As time went on he felt himself get pulled and pushed in numerous directions, his skin pulled onto a thin, too weak skeleton. Before being pulled off and restarting the feeling. Being framed and hung like a painting as he was stretched beyond imagination.
He felt—or not felt, he didn’t have the capacity for that— he was being manipulated over and over again. The frame was too small, the skeleton too weak to hold him up. Too dead for something that was still alive. Still moving. Still existing.
—
A lot of things are wrong. Kyōjurō wakes up in a dumpster, Obanai gets cps called on him, Mitsuri realizes these are not her parents, Sanemi is an orphan but its not his fault this time, and they all gain super cool quirks
Oh, and they’re all supposed to be dead too

Summary
PLEASE READ ALL TAGS THERE MAY BE MORE ADDED LATER ON!!!!
Kyojuro has been told he didn't win the life lottery considering his mother being dead his father being an abusive alcoholic and his little brother unable to use breathing styles. Even then Kyojuro would still say that he was very blessed. Sure, Kyojuro will say that some parts of his life were bad but some parts were just as good. He loved all of them. He was fine with the life that he had as he thought he was lucky to be born to such a mother and to have his little brother by his side. It's a life he knew many would be jealous of and would never take it for granted.

Summary
The fire crackles, and the soft murmur of conversation around you fades into the background. You’re left with the sound of the wind and the distant call of an owl, the weight of Rengoku’s words lingering in the air. You feel his presence, a gentle warmth just beyond the circle of light, even when you’re not sure if you deserve it. In the quiet, you let yourself feel it all—the bittersweet, the confusion, and the fear you can’t yet name.
The realization settles over you like a slow dawn: you’re in love with him. Deeply, foolishly, impossibly in love. And there’s no denying it anymore.
