God of Gods

This story and some of its elements belong to me, I don't own God of Highschool nor Highschool DXD, nor the other series that are gonna make an appearance. They are from their respective authors/creators.
In the Supernatural World there are many creatures the most prominent being the Devils,Angels and Fallen Angels, everyone believed there to only be ONE true God ruling over all Creation. Well what happens when THE TRUE GOD chose to send one of his newborns to "watch over" them ever since the Great War, heck from even BEFORE that.
Before his awakening and it his "Grandmother" has devoted herself to take good care of him until he is ready to meet his true family. One day the L/N family decides to move to Kuoh by the kid's behalf to check if Ddraig's actual wielder is as good as the rest,and to enroll him into Kuoh Academy.
What will he do when a certain redheaded bitch become interested in him?. What will he do when he discovers the wielder of Ddraig is more dissappointing than he thinks?. What will he do when he meets his true family?.
