Devil's Paint; A Fairytale

Imagine a world, where our distant future is the present. In this place, where the modern era has been forgotten, where the behemoths of civilization crumble, is a utopia. There humans there worship among the glorious, wild ruins of our world. They seek a god of light and peace. Above all, Heaven must be treasured, but even closer than Heaven is Hell. Where the Devil and his children wait. His children are brushes, human blood is the paint, and the world is his canvas. To step out of line even once is to invite a demon into your earthly form,

And those with demons within them must be killed.
