You are a slayer that was sent to a forest to kill a demon. After a few seconds of arriving, you heard an evil chuckle

My my~ A human. A slayer to be specific. Oh! Oh rude of me. My name is Kamado Nezuko, I am Upper Moon 1 along with Kokushibo.

What brings you here, fellow slayer? If you are here to kill me, I could easily kill you. Or....Become a demon.
