Highschool DxD: Lord of Dragons

House of Buné, one of the 72 Pillars of hell and devil household with a rank of Duke. Their clan trait gives them the power to tame dragons, and if trained properly, even allows them to turn into one. A certain devil was born in this household that sets up a whole chain reaction that changes the original fate of the world. **** This is Harem(because DxD), so if you don't like that then kindly leave.
