The End of Onslaught
To the vampire, the name "Hellsing clan" was akin to that of a monstrous creature lurking under the bed. Every vampire who had lived from the early Renaissance to the end of World War II was well aware of the terror unleashed by the Hellsing clan upon vampires and all monster creatures of the Curtained World.
Their relentless pursuit and unwavering determination made them formidable adversaries, aided by an ever-evolving arsenal of advanced tools and killing methods with the advancement of human technology.
The belief that vampire hunters had become extinct was partly due to the annihilation of the Hellsing clan during World War II. While the Hellsing clan posed a significant threat to vampires, their numbers were limited, and they remained human. Furthermore, the later generations of the Hellsing clan were considerably weaker than their predecessors during the early Renaissance.
