What if Nezuko Kamado was the only survivor? What if Tanjiro too, died in that incident with his family? ..and, what if she encountered a demon slayer? And what if that demon slayer happens to be a pillar that is willing to kill any demon they see without second thoughts? And if that very pillar spared Nezuko's life, would this endanger his life instead? Follow the adventures of the demon named Nezuko Kamado and the pillar that spared her life.. as they meet humans and demons with relationships of not hate, but of peace. (Demon Slayer:KnY isn't mine. It is respectfully made by it's author: Koyoharu Goutoge. The only thing I own here is the storyline and a bit of fanmade characters.) A fanfiction alternate universe series! (Please don't hate me)
