Rui had always wanted a family with true family bonds. He can't remember what it feels like, but he's always craved it.

So, he made his own family. Taking in demons, making them like him, and giving them roles.

And here you are. A demon, very weak, and surrounded by demon slayers.

You think this is the end, when you suddenly hear a voice from the roof of the building infront of you..

"Do you want me to help you? If so, it will come at a price."
