My little slayer [Muzan x Tanjiro]

Chapter 1: Meeting a demon

Tanjiro's POV (might contain spoilers.) :

'This place is a bit crowded... the buildings are so tall!! What is this place?!' I look around at this place called Tokyo, I was surprised on how advanced this place is, I walked slowly by the crowds. I didn't bring Nezuko today, since she'll be resting and that I don't want her to get injured again..

A few walks later, I got tired.. "I'm hungry" I said putting my hand on my stomach, I continued to walk until I find this guy sitting and on his store, Looking at the sign.. I can tell his selling Udon!  "Hey.. excuse me.. A bowl of Udon with grated yam on top please." I smiled, "O-of course!" He said and hurriedly go inside. I sat on the bench and waited patiently for my order. "Hey, Kid! Here's your food!" He said behind me and I startled "ah! Thank you!" I took my food and sip on the hot soup of Udom. "Ahh... just right." I said closing my eyes, A wind passed by and I smelled a scent that is familiar on me. I stood up as my eyes widened and I accidentally dropped my bowl, I held tight to my sword and ran away. As hurried as I can be, I continued to follow that scent, I slowly pushed some people that are on my way.

  This scent!! This scent is familiar! I've smelled this scent before! This is the scent that I smelled in my house!!"

As I got closer on that scent. I realized that I've found him..Muzan Kibutsuji! I hold on to his shoulder and he gave me a glare. My blood boiled in anger, 'that demon!' I said to myself, I slowly took my sword on my hips, ready to slash him in his neck even in this crowded place but I suddenly  heard a child's voice.. what?? 

 "Daddy?? Who is that??"

 I was shocked.. A KID..??? How could this be?  He turned the kid facing me because he was carrying her, I covered my mouth in panic.. This guy... HE'S PRETENDING TO BE A HUMAN!! Can't you see!? He's a demon!!"

I felt bad on the child and to her mother as well.. not knowing that the person they love is a demon..

"Dear?? What happened??" A lady said to him, "Who is that young man??" The lady questioned.. is she... his wife..? Her sweet tone give me anger, not because of the wife, But because of this Demon, Muzan. "I don't know.. I haven't seen this kid before.." He looked at me with a straight face, "Oh..?" the lady said curiously. 

"Why do you have a..." 

"A child?? Well... what's the problem?? It's normal to have children's."

 He said with a smile on his face, yet.. I feel disgusted.. don't play tricks on me Muzan.. like.. How many people have you turned into a demon?!

"Excuse us, but we gotta get going." He said and both of his family left.
