Aerrin Blackwood is just an ordinary boy... or so he thought. After an attack on his home village Aerrin met an old dragon by the name of Airelorn. Who tells him that he is no ordinary boy but a being known as the DragonBane. While normally he would have lifetimes to learn and master his powers a great evil rises to take his power. Aerrin and his faithful companions - an elf prince, a cursed orc, and a half-demon warrior - will race against time itself or lose their world forever. (The contents of the book are subject to change as this is not the final draft. Expect many changes as the story is edited.)

"Why me? Why did this happen to me? My life has always been hell from the second I was born. So why...? WHY WAS I TURNED INTO A GHOUL?!" Never trust a cute face. That's something Rin learned the hard way when he was lured into a ghoul's trap and had a hole punched through his lung, left to bleed to death where nobody would ever find him. That is, until a white-haired stranger saved him, though living came at a cost: Rin would have to sacrifice the last of his humanity to become a creature that everybody, both humans and demons alike, fear. If he wishes to return home, he's going to have to learn how to control his hunger before it leads him into doing something that he'll regret. But with this new way of life constantly toying with his emotions, keeping his new desire in check is going to be much more difficult than he or Kaneki ever imagined.

Just a idea I got inspired from the Fate Series in general and I don't really have a good summery to put but just to explain the plot a bit. The child of Shirou Emiya and his Servant Saber aka Artoria Pendragon is sent into the world of DxD. The world shall see what a true holy Sword is as the child of infinite blades becomes a hero of justice in his father's place.
