Dhampir in DxD

A young man dies at the hands of bats of all things. When this happens he gets reincarnated into DxD as a dhampir, and as the son of a faction leader, but not one that should exist. Even so he’s not one to look a gift horse in the mouth. So using his newfound powers he will survive in the world of DxD and build a harem of beauties to boot. PS: The harem will only consist of 3 to 6 women, no more and no less.
