HIS Demon Slayer: Yandere Various Demon Slayer X Female Tanjiro Reader

Punishment

[Hello, My Sexy Muffins! For Those Who did know I binged season 1 of Demon Slayer watched 8 episodes of Season 1 and Watched the Movie... You ALL Should have seen this story coming! Also, Reader is 18 in this and then she ages up after her training so I think she will be twenty soon! So let's do this! All ROMANTIC CHARACTERS ARE 18 OR OLDER!!!] 

(Someone ???' POV) 

I could smell her, I knew she was nearby. I do not have long before the sun is up. I rush up the mountain. She lives here? I slam the door open and a woman demands to know who I am. I say nothing and sniff the air... Damnit she is not here? 

"Do you have a Daughter, by the name of (Name)." I say and the woman's eyes widen. 

"Wh-What! What do you want with m-" I did not waste another second and slashed her throat. 

My (Name) is not here and all of these humans are keeping her from me. I massacre them, except for one. I need to punish (Name) so I spill my blood into one of her sisters. That will teach her to not be here. I then turn on my heel and leave. 

The Sun would be up soon, I cannot risk getting in the sunlight if (Name) has been reborn once more. 

-Time Skip, Brought to You By: The Family Massacre That Changed Everything-

(Name's) POV) 

I am walking up the mountain, a little bit tempted to eat the candy I got for my siblings. It just sounded so good right now. I stop as I smell something in the distance... It was Blood! 

I start running up the rest of the mountain my legs almost cramping as I trudge through the snow at top speed. When I made it home, I saw Nezuko, covering our baby brother. I rush up to her tears running down my cheeks. 

"NEZUKO!" I cry out and kneel next to her. "What happened!?" 

I freeze out of the corner of my eyes, I see the rest of my family. They were all dead. I quickly wipe away my tears and check all of them. Nezuko is the only one that is warm. 

I grab her on my back and rush down the mountain or try to. Did a bear that could not find a place to sleep for winter find them? Or did a madman come up the mountain? It does not matter. The thing that matters is that I have to save my sister. Focus on getting to town, so she can get treated. That is all that matters, it does not matter that my lungs are burning. Or That my legs are cramping! None of that matte-

I slipped in the snow and fell. I get the wind knocked out of me. I realize the snow has saved my life. But also, I only fell because of the snow in the first place. 

Nezuko! 

I sit up fast and look around. There she was standing up. That was a good sign! She is okay enough to stand. 

"Nezuko!" I call, rushing over to her. "You do not have to walk let me carry you..." 

I stop as I see something is not right... She looks up at me and her eyes have changed and she is growling at me. Suddenly she tackles me to the ground and tries to bite me! I bring my hatchet up and use the handle to put it in between her mouth. 

What... What has happened to her? The words that the old man told me. About demons, Nezuko has been turned into a Demon. This is all my fault! 

"I-I am sorry," I say trying to hold back the tears. "While I was sleeping soundly, you and our family... They were all being killed! You must have suffered! I am sorry Nezuko... I am so sorry... You have to hang in there! I will save you! You have to... You have to fight it!" 

Suddenly she starts to cry and her tears fall onto my face. I am shocked, but see someone behind her, and so does she, I grab her by her throat and flip us away. She almost got cut by a sword! We roll and I hit my back into a tree groaning. Fuck that hurt. 

[YASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS first chapter done! I hope you all enjoyed and stay sexy all my sexy muffins! And Nezuko is NOT Yandere in this!]
