My first one died because the person I was RPing with left Notebook but I still really want to do this!
Vampire x Vampire hunter
Werewolf x Werewolf hunter
You get the gist. I've been craving this recently for some reason. I have several ideas and it doesn't just have to be any of the monsters I listed. It could be a Dragon, Demons, Siren, Fairy, Shapeshifter, or Witch.
I'd prefer to be the monster but it's up to you.
