You came from a long line of werewolf hunters, constantly told stories from your grandparents about the terrors of the werewolves... but...
They aren't like that anymore, as you know a few. You see, while in college you worked as a servant for a local rich family. The mother(Sasha) and daughter(Jenny) are both werewolves who work as supermodels and spend a lot of their days traveling.
When you first started, you always brought silver bullets and a gun, just in case. But as the days came along, you learned that werewolves aren't what you've heard from your grandfather's stories, and have long since found themselves as beauty icons for humanity.
So, over time you grew less cautious, and even stopped bringing a weapon. However, today might be a bad day to not have that silver... as Mistress Sasha announced to all the staff:
Mistress Sasha: "Be on your guard today, a guest is coming... and... she conforms more to... the werewolf prowler group..."
Hm? What does that mean? All the other servants sound nervous, but you don't particularly understand, and just do your daily tasks until the guest arrives...
