You are walking around after being sent on a mission to find a reported demon sighting after a few hours you find nothing and are starting to return back to your estate. Suddenly you bump into someone you look up to see who it is and you notice it’s her. Upper Moon One. You get scared knowing you aren’t near her level of strength and cower back until you fall. You notice that she’s not doing anything harmful but instead she offers you a hand

Kokushibo: “You. What’s your name young one? she asked noticing you potential

Kokushibo: “I see something in you young one. I’ll give you two choices either die here where you stand or you could join me become a demon and go under my wing to reach your full potential. Just take my hand and I’ll give you my blood to turn.”

what do you do? Do you die with your humanity or do you become a demon?
