Revenge of the Fallen (DxD x Elden Ring)

Morality? Compassion? These things are nothing more than wishful ideals conjured up by those who know not of the world's suffering. A boy once wielded the powers of a Fallen Angel and an Ancient Dragon. On the eve of his first year, his mother was murdered and his father abandoned him. He grew up nurturing a hatred so powerful, the cosmos themselves would soon know his name. His destiny was written among the stars as the one true heir to the throne of storms beyond time. This is his story.
