High School DxD: Reborn as a noble devil

Nero is a guy who died in his original world and got reborn in the body of a human in another world. He always thought that his memories in infancy were random dreams, but he died again and got back to his original body with the memories of both life experiences and the knowledge that he got in the human life. And that is the start of his life in the world in the Draconic Deus universe. *All the photos and the universe of Highschool DxD are not owned by me.
