Muzan had found the kamado's who were the descendants of yoriichi, he killed the family but found a baby tanjiro and was intrigued by tanjiro that he showed no fears towards him. Now he raised and trained him to be a spy for muzan and hopefully bring down the demon slayer Corp

First story so please no hate but anyway. What if Muzan had the idea to make the perfect demon, not one that could walk in the sun although he would like that, and might happen. He wants a demon that he could be able to mold and shape and put his beliefs in. So he had a wonderful idea to take a child and raise them as his own and twist the world. Will his idea work or will it fail? read on to find out. And you as the reader will get to decide what happen so I can try to please most of you ?. And I apologize in advance for any spelling mistakes in the story. ⚠️Warning ⚠️: I do NOT own demon slayer or any of the characters all rights go to Koyoharu Gotouge!! Also this isn't a Muzan x Tanjiro story!!

There's a new pillar! Giyuutan zenitsu and inosuke do not know Tanjiro Tanjiro is the new sun pillar Tanjiro whole family died just like in the anime and nezuko is human Tanjiro - 18 Giyuu - 19 Shinobu -18 Rengoku - 20 Uzui - 23 Gyomei - 25 Mitsuri - 17 Iguro - 17 Sanemi - 19 Muichiro - 14 Zenitsu - 15 Inosuke - 15 Aoi - 14 Kanao - 14 Nezuko - 13

Amidst a violent snow storm up in the mountains, two demons were sent out to extinguish the last living relations to the sun breathers. The Kamados. "Oi stop messing around you woman obsessed freak!" "Come on don't be so up tight!" "Huh... what's this?" A small child appeared from behind a snow covered bush, a small note tied to his neck as his bright red eyes stared at them inquisitively. "Tanjiro Kamado... you don't say" **** "You are to infiltrate the demon slayer corps and gain their trust Tanjiro. I'll always be with you, don't forget that" the demon king stated, his tone surprisingly soft. "Yes father"

What would happen if nezuko died of hypothermia instead of becoming a demon? What if tanjiro became a demon instead? ~~~ Tanjiro walks mindlessly through the snowy night, unaware of what he has become. He enters a small inn that seems to be abandoned, he sits there blankly staring at the floor with tears in his eyes. '...w-why them..?' 'why me..?' ~~~ ⚠️ Not a ship

Tanjiro, an 18-year-old boy finds himself in a bad blizzard. He had gone out to try to sell some charcoal, but no one cared. He was worthless they said. They said everyone would've been better without him. No one cared. Not even his own family. They blatantly expressed their hate towards him when given punishments way worse than the rest. Starvation for days. Weeks. Leaving him out in the freezing snow. They didn't care, nobody did. Until one man found him out in the freezing snow. A slim, pale man. A simple man who would change his life forever. That man's name, was to never be uttered by anyone's mouth. The name of Muzan Kibutsuji. (The cover on this story is not mine, Credits to owner.)
