Mythology System in High School DxD

What does it mean to be abandoned by the gods? Eden grew up a bastion of pestilence. His first memory was shrouded by a haze of blue and red light, the orphanage he called home was now little more than a blazing conflagration, everything, everyone he interacted with would meet adversity. That was until he died, at the age of five, his mind unable to comprehend how the world works he merely accepted his fate, a willing martyr, yet, death wasn't the end. Given a chance to start anew in the world of high school, DxD watch how Eden takes to a throne beyond that of either heaven or hell.
