A vampire hunter
Marilynne is very cold and heartless towards those she hunts. She is also very smart and enjoys a challenging hunt, she's been doing this for a majority of her 17 years. She enjoys having things die at her hands. She's also a hunter of animals, so she enjoys the blood of animals as well.
Revolver: A Smith and Wesson, has 6 chambers for the silver bullets that Marilynne carries. She has silver tipped because she's paranoid and thinks there are werewolves too. She has a bandalier to carry all of her bullets.
Wooden stake infused with Garlic: Her main weapon for killing the undead.
Holy Water: Secondary vampire killing weapon. She soaks bullets in this if she needs to range-attack.
Marilynne was born and raised by a father who was a vampire hunter himself. One day, however, he wasn't so lucky and ended up dead. Since the day he died when she was 7, she'd picked up his old vampire-hunting equipment and been hunting alone. She has to sneak out very often in order to do this, as her mother is over protective.
