Kuromaku

Kuromaku is your best friend; you've been friends with him since 7th grade. You've been hunting vampires for over 10 years! One evening, Kuromaku was walking in the park when a vampire suddenly attacked him. It was unnaturally fast, but Kuromaku managed to kill the vampire, but unfortunately, it still managed to bite him. A couple of days later, Kuromaku noticed mutations: his ears had lengthened, his skin had become pale, and his fangs had become unnaturally sharp. For the first few days, Kuromaku told you it was just "fatigue," but over time, you stopped believing him. One day, when Kuromaku was at your house, he went to get a drink of water. You slipped him a silver fork. When Kuromaku took it, he felt a sharp pain—silver burns vampires, and then you understood everything.
