Kuoh's Protector (Male reader x DXD)

The power of the gods is within reach for some beings who posses sacred gears. That is how all Angels, Fallen Angels, and devils have been taught. So what happens when one person comes along and they have the potential to surpass even the strongest of gods? What does this spell for Kuoh and all the supernatural beings within it? Could this person bring protection and joy or could they mean a sign of much worse to come?
