**No ones POV**   

   One day, a girl at the age of 4 was out with her mother. She always wondered why her mother carried fans with her. They went shopping that day and were on their way home, the sun was already almost completely out of view. The girl saw something shiny and wandered away from her mother. But instead, only got greeted by a creature she was never aware of, a demon.

**Y/N POV**

   I was walking with Okaasan but I saw something shiny. I wanted to see it. I let go of Okaasan's hand and went to the shiny thing. Just as I was about to reach for it, a strange looking thing jumped in front of me. It had weird kind of eyes on it's face. It has a number on it's left eye reading "lower moon 6". I was confused but then screamed after the thing was coming closer and I started running deeper into the forest.

   I kept running till I heard the thing say "Oooooo~! What's a young girl like you doing here alone~! It's dangerous to go out alone~.". I turned around and said "P-PLEASE! LEAVE ME ALONE!". The demon chuckled and said "hehehe, no can do. You're my meal for tonight~". I stared with trembling wide eyes. "OKAASAN!!!!". "Oh hush little girl! No one's coming for you... You're my dinner tonight.". The things' hands glowed orange then random dolls came out of the ground. The started shooting things at me and I screamed as loud as a I could. 

It was just about lunge and bite at me before I heard "Breath of Music fourth form: Melodies teleportation".  All the things that were coming towards me went away and saw my mother jump in front of me holding the fans I so ever wondered about. I looked up at her in awe.. "No one. Touches my daughter.". She runs very fast towards the thing, and proceeds to fight it with her fans in combat. She looked so graceful doing it. Soon I see the head of the thing slide off it's body. I look over and see mother. "OKAASAN!". I run over to her and hug her, while she embraces me back. "I'm glad your safe, N/n.". I look over my shoulder and see the thing fading away.

I turned back to my Okaasan and asked "Okaasan, what was that thing?". Okaasan sighed and said "Let's head back home before I explain everything sweetie. O bachan is probably waiting for us.". "OK!". And with that we headed home. Once we got home it was already only a few hours before sunrise, O bachan engulfed me in a hug. "YOUNG DEARIE! WHERE WERE YOU THIS WHOLE TIME?! WHY ARE YOU HOME SO LATE?!" I noticed she sent Okaasan a little glare. "M/n L/n. Why are you two home so late?." My mother sweated and chuckled nervously "Well, on our way back, we went through the forest. And we encountered.... another one.". My grandma's eyes widened. "So.... N/n saw all of it?" My mother gulped a bit. "H-Hai Okaasan." " What was that thing?" They looked at me. "Come here dearie, it's time we tell you something about our world."

We got in the house and sat down. "It's time we tell you about creatures that live in our world N/n." My mother started. " There are man-eating creatures in this world called demons y/n. They start off as human, but if they ever get exposed to the demon progenitors blood, by force or not, they turn into a demon. The demon progenitor has plum red cat like eyes and pale skin with black hair and his name is Kibutsuji Muzan. After he turns people to demons, some demons who have eaten enough humans and are strong enough, they get powers called 'Blood demon art'. It can be anything so you must be careful." " Is blood demon art like the dolls made from fire?" "Yes N/n". "I have another question. What does it mean when it it's eye said 'lower moon 6' ?" My grandmother shot another glare at my mother.
