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.)

"Oh hello Oyakata-sama. Nice to meet you." Tanjiro was smiling brightly while his sister was riding in a box on his back covered with a cloth.

"You must be Tanjiro-kun that Giyu-san had sent a message about." The man with the damaged body said smiling slightly at Tanjiro.

"Kamado Tanjiro at your service sir. On my back is my younger sister Nezuko." Tanjiro said bowing in respect to the old man and then turning his attention to the Pillars and tilted his head.

"From what I understand you know things that no normal person should. Correct?" Kagaya asked staring at Tanjiro who was staring at the others although his gaze was locked onto an androgynes figure who was staring blankly off in another direction.

"Yes sir." Tanjiro said with a nod of his head.

"Oyakata-sama what can this snot nosed mountain brat possibly know that gathered your attention?" The white haired man asked glaring at Tanjiro who glanced at him curiously.

"Would you like to tell them yourself Tanjiro-kun or would you like to demonstrate your other ability first so that they do not deem you a liar?" Kagaya asked looking at Tanjiro who hummed slightly.

"Perhaps I should demonstrate the other ability, it would answer a few of their questions." Tanjiro said and he looked slowly over all of the pillars.

"Giyu-san already tested my ability, of course it also helped reassure him that he really does deserve his position as a pillar since I could pass on the messages from his sister and Sabito-san." Tanjiro said and the others looked confused and stared at Giyu who nodded slightly and Tanjiro looked at the tallest of the group.

"Himejima Gyomei-san correct? You used to work as a monk at a temple and took in children, the only survivor of a demon attack caused by another child you took care of was Sayo-chan. You beath the demons head off over and over all night in order to protect her until the sun came up and killed the demon for good. Thanks to misunderstanding Sayo-chans words you spent some time in prison before Oyakata-sama got you out and recruited you to be a demon slayer. Some of the children are still watching over you although they do leave on occasion to check on Sayo-chan who wants to apologize to you and also to Upper Rank 6 Kaigaku since he's the one who let the demons into your temple correct?" Tanjiro said all of this without moving his stare from Himejima who lowered his clasped hands as he stared sightlessly at Tanjiro.

"How? None…none of the others knew the full story…" Himejima said and Tanjiro smiled as he stepped over and reached up to grab the large mans hand and gently brought it down to his level.

"I can see those who have passed on and left the mortal world. They linger as spirits to watch over their loved ones. There are several children and young teens hanging off of you and standing around you right now. They're quite talkative and are sad that you blame yourself for their deaths. Here…let me try…" Tanjiro closed his eyes and took a deep breath, focusing on what he wanted to achieve. Then he moved Himejima's hand to the left a little bit and everyone could see soft see through tiny fingers land on the large hand.

"These hands…they're…" Himejima said softly and he immediately broke down crying, falling to his knees and there were soft see through hands that began to move through his hair and pet his shoulders.

"I'm sorry I can't make them fully seeable and touchable." Tanjiro apologized as he continued to hold the large mans hand while he bawled like a baby.

"That was…that was more than enough. Thank you…Thank you." Himejima sobbed out as he rubbed the tears from his eyes and stood up.

"H..What…" The androgynous figure asked, although Tanjiro's nose informed him that it was in fact a male in front of him, and he looked stunned and wide eyed.

"I can see, hear, talk to and even touch the deceased. They all get very talkative when they realize that someone is able to hear them and will listen." Tanjiro said smiling at him and then looked slightly to his left.

"Your twin brother and parents are here by the way Muishiro-san. They're upset that you've forgotten them but they understand that you couldn't help it." Tanjiro said and stepped forward, taking the boys hand and drawing in a deep breath. Three see through figures appeared, one of whom looked exactly like the boy whose eyes widened and he began to grab at his head.

"Nii-san…" Muishiro said whimpered slightly and there were tears in his eyes as he stared at them, finally remembering them. His parents rubbed his head and his brother hugged him, gently bonking his head against his twins. Before they vanished and Muishiro fell like a puppet with his strings cut, crying but smiling and hugging Tanjiro tightly.

That's how it went for each of the pillars. Tanjiro going to them and talking about their family or friend who had died and then somehow letting them see the ghostly figure and slightly touch them for a few seconds before they vanished again.

"Your older sister right? Kanae-san who was killed by Upper Moon One Douma? She seems to be both happy and upset. She's happy that you're smiling but upset that you use it to hide your emotions…and something about how you keep torturing poor Giyu-san and saying that no one likes him? Oh and how you should spend more time with Kanao-chan because she's hurting too." Tanjiro said to the last Pillar and then he stepped over to her and took her hand in his and took a deep breath again, causing everyone to back up shocked when a slightly older version of Shinobu appeared next to her in a bloodstained outfit and with a different butterfly clip in her hair.

"Ne…Nee-san…" Shinobu was wide eyed and stunned as she stared at her ghostly sister who smiled at her and reached forward, rubbing Shinobu's head softly before she faded slightly.

"Bring her back…please…please bring her back again! I…I need to talk to her! I need to hug her….I…I…" Shinobu begged as she sobbed into Tanjiros arms while he gave her a sad smile and then coughed into his kimono sleeve wetly.

"I'm sorry…I'm at my limit for today." Tanjiro apologized to her and her eyes were angry for a split second before she looked horrified when she saw the blood on his lips as he pulled his kimono sleeve away. The other pillars all jerked forward as well when Tanjiro stumbled slightly and wobbled dazedly.

"Even using my ability to that extent for that short of a time each…it's a bit outside of my power for now. I'm sorry." Tanjiro said apologizing to the pillars while they gathered around him and Kagaya was asking about what had happened.

"The spirit boys power seems to drain him greatly. He coughed up blood and seemed faint for a moment, the pillars are seeing to him." Amane softly informed her husband while their young son was sitting on his other side and looking both worried and a bit upset.

"I'll be alright. I just need to rest a while before doing that again. I've never done it so many times in a row much less for so many spirits at a time." Tanjiro said trying to reassure the pillars with a bright smile and Shinobu felt guilty for asking him to give her a little longer with her sister considering how badly it had affected him to give her just those few seconds.

"Thank you." Muichiro whispered softly as he supported Tanjiro on one side, giving the boy a soft smile that he happily returned.

"So…So the kid can see and talk to spirits. I can see how that's pretty important." Senemi said realizing now why the kid was brought before them.

"Oh that's not even why Giyu-san brought me here. I think it's cause of my breathing Technique." Tanjiro said with a smile full of sunshine and cheer.

"What style do you use?" Rengoku asked hoping the boy used Flame Style. He could have a cute little heir to being a Pillar then!

"Oh I use Sun style!" Tanjiro said with a bright smile as if he hadn't just flipped their whole worlds on their heads.
