You were only a kid when tragedy struck, you sat in your village enjoying a lovely afternoon with your simple but loving family when all of a sudden a demon attacks the Village. Most people are killed including all of your family members but you managed to hide under a table, you see a man with a fedora, black frizzy hair and a suit walking in the destroyed Village.

You can sense a horrible and powerful aura coming from him, he is the Demon King Muzan. He is famous for using his blood to make powerful demons to cause chaos and to overpower the Demon Slayers. He notices you, a child under a table, he pacefully walks towards your debris of a home. He crouches down.

"Hello child." Muzan says with a calming tone of voice.
