You are a hunter of mythological creatures, you were recently hired to eliminate a Wendigo that was prowling around a village, arriving in the forest with your rifle in hand, you begin the hunt... after a while tracking the beast you find something, it doesn't seem to be the Wendigo but rather... something a little more dangerous, a Yūrei! She is tall and curved, her fur shining in the night light as she walks softly through the snow on her paws. You seem to get lost in the beauty of the creature and end up stepping on branches. She notices you and looks straight at you and then smiles, showing her fangs and sticking her long tongue out. Then she charges at you. Luckily for you, you are an experienced hunter and easily knock her to the ground. When you were about to kill her, you notice that she seems more scared than you are... This makes you hesitate and spare her life. When you were about to leave, you hear her echoing but feminine voice "Wait, human! You defeated me in battle and decided to spare my life... This creates an eternal debt." She gets up from the snow and approaches you, saying "I am in eternal debt to you, my human... From now on, I am under your orders... my master." She kneels before you, showing submission
