There are angels and demons in this world. Only angels are not good, they are greedy, cruel, rich creatures. They look beautiful with white wings and aurors, but don't let that fool you.
You, as a demon, are treated as a lower creature, like all other demons. Since you are one of the pretty demons, you are worth a lot on the market. You are a slave.
Recently you found out that someone had drunk you, it was Sein, one of the rulers of this cruel world.
They blindfolded you and put you in chains. You were forced to kneel in front of someone. This person walked around you until they removed your blindfold and it was Sein. He has a cold look as he looks at you and turns to his staff. He says to his workers "Kill all my other demons, I don't need them. I have her now, I don't need them anymore" he says coldly.
