Chapter 1

1000 years before the main story and before the foreseeable demise of Muzan. A tall man with a pure white face and black eyes was walking around a town. This man was kibutsiji Muzan and he was part of the Ubuyashiki family which was a large family who were incredibly wealthy. Muzan had always been bored for as long as he could remember and had always longed for something more he wanted things to be different. As he was walking around he saw a girl who was smirking at him and inviting him to her house.

Months passed and the girl was pregnant and living alone, she was ostracized by her family and everyone around her for getting pregnant before marriage which made her lose everything. As time passed she remembered that the father of her child is a member of the Ubuyashiki family. No idea how to contact him she felt hopeless but would not give up. The women with black her fell to the floor in her grief and disappointment. " why did I sleep with him". She repeated that sentence over and over and over again. Remembering everything about that moment and not understanding what compelled her to sleep with that man.

There is nothing she could do now but accept that her life as she knows it is done for. No one could save her and she was all by herself. " bdm, bdm bdm" she could hear something. She looked around but didn't she anything. " bdm beep bdm beep" the sound became louder and louder which caused her legs to start moving. She kept moving and moving with no water and no breaks as her body became weaker and weaker. Her leg was falling apart and her flesh was rotting and yet the sound was getting louder which made her run even faster. " boom" she bumped into someone," what where you're going" says a man with red eyes but the same face and hair as the father of her child. " I have you're child help him survive please " and then her water breaks and her heart finally gives up.

Muzan pov:

I've lived my entire life in pure and utter boredom with nothing to excite me. Throughout my painful existence I had never felt and ounce of excitement until that day. A women who was one of the most beautiful women I had ever seen had invited me to bed her. I don't know why but at the time I felt something in my heart I thought it was because of the women but I had never been lustful before, so I now know the reason I excepted was different. I accepted because of what it would lead to. Born into the Ubuyashiki family I was treated as a replica and seen as spare parts for if my brothers died. I had no enjoyment in that life and I felt weak, powerless, useless. That was until I saw a certain flower. It had entranced me similar to how I felt with that women I didn't know what would happen. Then it happened my eyes changed my blood changed everything about me had transformed. I had become faster, stronger better. I knew that this was apart of my destiny so I knew that meeting that women had also been what fate had in store for me and would lead to something special.

I was just minding my own business when I saw a women with a massive belly ragged clothes gouged out eyes , her hands were bleeding and when I looked at her feet they were filled with blood. She had no more toes but was a mass of flesh boned and blood all jumbled together. I didn't recognize who this women was until she came near me. ' it's her, what happened to her. ' " bbm, bbm, bbm beeeeep" women had died and there was a child coming out of her. I gouged through her stomach and pulled the baby out safely. " so this is what fate had in store for me. A son." " HAHAHAHAHHHAHAAHHHAHHHAHHAHHAHA" "how hilarious I the first demon in existence has a son . I'll name you roku "

After the day Roku was born I told him about me and all my abilities and began raising him in hopes of giving him strength like mine. " wake up Roku it's time to kill a human
