Prologue-

We always thought that there were only two dimensions, Assiah, the realm of humans, and Gehenna, the realm of demons, but we were wrong so very, very wrong. It just happened to me one day, one moment I'm being a kick ass exorcist then the next I was falling. I hit a tree and was knocked out; I'm now in a hospital. I am alone here currently, and I still haven't figured out why this happened to me.
