Ao no Exorcist

This world consists of two dimensions together, like a mirror. The first is the world in which the people live, Assiah. The other is the world of demons, Gehenna. Generally, travel between the two, and really any kind of contact between the two are impossible.
But demons can pass into the world possessing something that exists within it. Satan is the god of demons, but one thing that he has, and this is substance in the human world that is powerful enough to contain it!
For this purpose he created Rin, his son with a human woman, but your child will agree with your projects? Or will he do more? A exorcist?
