Miss Kobayashi's Dragon Maid and her Halfbreed Bother

Violence, greed, lust, those are the traits that the humans and dragons have to those of Nergigante blood. Many feared the them as they were violent killers who slew anyone in there path, so a pact was made long ago to rid the world of them, the war was long and bloody, many lost their lives, many dragons went extinct, but they drove the devil dragons into near extinction themselves. If any were to show themselves they would be hunted down and killed on the spot. But what if they were not all monsters? What if one found love in a human and settled down and had a child? One that with human blood could resist the urge to kill and feed? Well one did and those of the world found out, in a last effort and to save their kind's blood the last known living Nergigante opened a portal to another world and set his son through before being slaughtered along with his wife. And what happens when this child finds a new family in this new world?"
