TBH I would like to know
how ,in a world where anyone that knows of vampires is either made a vampire, a servant or killed, a person can
become a vampire hunter. This is not your typical vampire setting, after all ... no church or ancient society to accomodate our would-be Van Helsings , for starters.
I wonder if our vampire hunter is actually a ex-servant of some ( dead or not ) vampire. It seems to me the more logical backround to a vampire hunter in this setting ... you would know of them ( even be familiar with their weaknesses ), would not be killed and , like we seen about Menhera, you get a boost in your physical abililties ( something you would need to hunt vampires in here ). Or worse, she is a vampire herself ... ( that would explain her unheathy attraction by the MC ... apparently all the female vampires around tend to salivate when he gets close
)
