Demon Slayer AU

(A/N: I own nothing and it was just a little blurb that hit me so I had to write it. Maybe a bit OOC.)

"You're married?!" More than one voice asked in disbelief and shock as Shinobu finally lowered her sword from Sanemi's neck and instead moved to Tanjiro, happily laying her head on his shoulder.

"When did that happen?!" Mitsuri asked with a squeal as she stared at Shinobu betrayed that she hadn't known.

"Two years ago." Shinobu said giving them all an annoyed look.

"About three months before Muzan killed the rest of my family, as soon as I turned fourteen." Tanjiro said nodding his head in agreement.

"How come we didn't know?" Rangoku asked staring at the two of them and a vein in Shinobu's forehead popped.

"You would have if you had accepted the wedding invitations I had given you! Or even just read them! I handed one to each of you myself and asked Himejima-san to hand one to Oyakata-sama!" Shinobu said glaring at them all and Tanjiro rubbed her back soothingly while he shot them a dark look. Shinobu had been upset but understanding that the Pillars couldn't make it, thinking that they were all busy with training or killing demons, but now to hear that they didn't even read the invitations?

"I never got the invitation Shinobu-chan. I sincerely apologize, I would have been there if I had known." Kagaya apologized and he didn't seem very happy as he looked towards the others.

"Ah, I could not read it and when I asked Shinazugawa-san to read it he became annoyed and ripped it up telling me that it was a prank or joke from you." Himejima said and the others all nodded their heads.

"Yeah Shinazugawa-san came and told me it was fake as well, and I relayed as such to Kanroji-san and Uzui-san when I ran into them." Obanai said from where he was over beside the tree. Kanroji let out a loud wail and threw herself at Shinobu apologizing for not being there and for believing Obanai.

"I was told the same." Giyu said and Rengoku agreed while Muichiro nodded his head in agreement as well.

"Oh so you're the reason why my wife was so upset?" Tanjiro turned blazing angry eyes towards the wind pillar who seemed to realize that he had made an error in judgement by claiming the wedding invites were a fake as all of the Hashira turned unhappy eyes towards him.

"Can you blame me for thinking it was a fake? Who'd want to marry he-"

Slam!

Crunch!

"I did. I wanted to and did marry her and I don't like what you're implying about my wife." Tanjiro said glaring as he stood over a downed Sanemi who was clutching his nose.

"Oh my. I think you managed to break his nose dear." Shinobu said looking amused after her husband had just headbutted the wind Hashira in the nose.

"Less than what he deserves." Tanjiro said chirping at her happily now and she giggled when she saw he wasn't even slightly wounded by it.

"Protective and vindictive little brat aren't you?" Tengen asked grinning slightly as he looked at Tanjiro who raised an eyebrow back at him.

"If he was talking about your wife how would you react?" Tanjiro asked and Tengen's eyes went dark at this.

"I see your point. Oi Kochou-san, sorry I wasn't there for your flamboyant wedding. I guarantee you my wives are going to be upset that they missed it, you should probably expect them to want you and your husband to come visit sometime soon." Tengen said making Shinobu chuckle slightly.

"I'm sure. I'll let you know when I can Uzui-san." Shinobu said making the man grin and flash her a thumbs up.

"I apologize for not being there as well Shinobu-chan. If I had been aware of it I would have made sure that I had been there or at least sent you a wedding present." Kagaya said apologizing and the other Pillars likewise apologized, more than one of them glaring at Sanemi.

"If we're done with all of you revealing what a jerk Shinazugawa-san can be, may I ask what the meeting was originally about? Surely it's not just about Nezuko-chan traveling with Tanjiro since Oyakata-sama had known from the beginning." Shinobu said calmly as everyone turned back to the meeting at hand.

From there things played out mostly how they did in the anime right up until Nezuko exited the box while Obanai held down Tanjiro.

Nezuko glared at Sanemi and then turned away and glared darkly at Obanai.

"I don't really like you holding down my husband Iguro-san and it would be in your best interest to release him." Shinobu said smiling and causing Obanai to look at her wary and confused.

"I'd dodge if I were, oh my it seems my warning was too late. Tragic." Shinobu didn't bat an eye when a familiar box slammed into Obanai and knocked him off of Tanjiro.

"Mmm? Mmm Mph." Nezuko made an upset noise as she looked at her brother with tears in her eyes while Mitsuri was doing her best not to laugh at Obanai being taken out with a box.

"It's okay Nezuko-chan. See? Onii-chan is just fine." Tanjiro said soothingly as he approached the tatami room but paused a few steps short when Sanemi thrust his bleeding arm in front of his sisters face.

Nezuko gave him an annoyed look and turned her head away, turning it away two more times when he kept trying to put his bleeding hand in her face.

"Stranger danger Nezuko-chan." Shinobu said calmly and Nezuko's eyes brightened before her leg lashed out.

Even Kagaya winced slightly despite not being able to see while Tanjiro grinned.

"I love that you taught her that." Tanjiro said grinning at his wife who smirked slightly while Nezuko made a faint whining noise and was in her tiny form as she made grabby hands at her brother with tears in her eyes.

"Please come comfort your sister Tanjiro-san." Kagaya said immediately.

"Before she does that to me." Kagaya muttered quietly while his daughter was wide eyed at how easily a Hashira had went down in one move. She had to remember that the next time one of the new Slayers that survived Final Exam manhandled her. If it worked on a Hashira it would definitely worked on the new low ranked Slayers.

"It's okay Nezuko-chan. See? Onii-chan is just fine and look! There's your Shinobu-onee-san right there. You know how protective she is of me and I am of her. We won't let anyone hurt each other." Tanjiro was hugging his sister and rubbing her head gently while she made grabby hands at Shinobu who approached as well and stayed at the very edge of the tatami as she reached out to rub Nezuko's head as well.

"They look like a family father. Like you and mother did when Kuina and Kanata were born." Kiriya relayed to his father and both Tanjiro and Shinobu went bright red almost instantly but didn't look displeased while Nezuko made a happy noise as she nudged her head up into Shinobu's hand while also cuddling closer to Tanjiro.

"Please do make sure you tell me personally if you end up expecting a child Shinobu-chan. That way there are no further miscommunications and you would not be in danger of losing the child due to your missions." Kagaya said and Shinobu blushed wider but looked at Tanjiro and smiled when he grinned at her.

"Of course Oyakata-sama. Nezuko-chan you're going to have to go back into your box for a while okay? I'm going to have you and Tanjiro taken to Butterfly Estate so that he could have his injuries taken care of. Be a good girl and I'll show you the gold fish, you wanted to see them right?" Shinobu asked smiling at the girl while Kanroji helpfully brought the box back over and smiled at the girl who dove into it gleefully and closed the door.

"See you soon dear." Shinobu said kissing Tanjiro lightly while he grinned at her as the Kokuchi who had approached to take him to Butterfly Estate gaped at the sight of Shinobu kissing this low ranking Slayer.

"See you later love." Tanjiro said happily as he was taken away while Shinobu smiled and kneeled back in place next to Kanroji, who was grinning and gushing and blushing as she poked at Shinobu. Shinobu knew she'd be bothered for details on her love life by the other female Hashira later.

"Did you really teach that girl to kick guys in between the legs?" Obanai asked looking at Shinobu who smiled softly and a bit sadly.

"No." Shinobu said calmly and a bit sadly.

"I taught the entire family to do that. Shame it doesn't work on demons." Shinobu said with a heavy sigh and Kanroji suddenly started laughing hard.

"Can you imagine the looks on the demons faces if someone did that?" Kanroji asked when she finally settled down a bit.

Not even Kagaya could help but feel a bit amused and a bit of pity when he imagined Muzan or one of the other demons taking a kick to the jewels from a young Slayer.

"I'll try that out next time."

Shinobu's promise had the other Hashira and Kagaya actually feeling a bit sorry for the next demon who faced off against the shortest of the Pillars.

"Can you teach me that trick?" They all were horrified at Kanata's request as she stared at Shinobu who gave a small grin.

"Of course young princess."
