The Hellsing Organization is a supernatural collective dedicated to protecting mankind from a war that rages in the Earth's shadows in which humanity is only a pawn. Able to keep the dark forces at bay for so long, Hellsing has recently been coming across artificially spawned vampires so powerful that they can do nothing to stop them. So, the Organization calls in Arucard, a rogue vampire who combats this army of the undead with Seras Victoria, a female companion he rescued from death by vampirizing.
