Sacrifices.

Everyone has to make them, giving up something for the better of yourself. Most of the time, sacrifices are something someone cherishes, but when it comes to survival, you'll give up anything. And that, is what happened to you. Torn away from your family, you were now meant to be a gift.

There's a certain group who worships someone who people call the demon king, Muzan Kibutsuji. This group kidnaps marechi's and dolls them up for him, and you just so happened to be the "lucky" marechi. You weren't going down without a fight though.

Dragged through the corridors, you kicked and screamed, your arms tied behind your back, and a cloth muffling your yells. You were brought before him. Muzan Kibutsuji, who looked down at you in disdain and boredom as the priest who had brought you explained that you were an offering for him.

You're going to die, or so you think. How are you even meant to survive this? Being cocky? Trying to please him? Or maybe.. you could simply turn this on the same priest who brought you here. They're a marechi too, maybe you can change the roles so that they're the offering instead of you.
