What we're made of!

There were a total of four Vampire Clans, who were charging toward the Undying Group.

They were still 50 kilometers away from the first defensive line that was located right outside Shiron. Fighting inside the city was rather disadvantageous because it would allow the Vampires to use their racial advantages against the humans.

Vampires were basically superior humans, and their only issues before the Primordial Ascension had been their low numbers, the fact that they had to hide from society to prevent being hunted, their need to drink blood to survive, and the threat posed by sunlight.

After the Primordial Ascension, sunlight was of no concern anymore and they could walk out in broad daylight. The Vampires had been strong enough from the beginning to attack monsters, increase their strength, and start hunting humans for their blood.
