D

D is a dhampir, a half-breed. He doesn't look older than twenty. D has a beautiful, refined face of aristocratic type, pale skin, and black curly hair; he is tall and slender. His style of dress is an inconspicuous dark suit, a wide-brimmed hat, and a long cloak. His only weapon is a long, double-edged katana, which easily cuts through even stone and steel.
The hunter's face is almost always calm and expressionless, his voice is quiet and even. D speaks little, uttering short phrases and only occasionally condescending to normal speech. The dhampir's true emotions manifest only when the vampire part of his being prevails over the human. Being a half-breed, D is immune to crucifixes and sunlight, although a temporary trap created by vampires, turning night into a sunny day, can cause him severe pain. At the same time, the hunter's strength, reaction speed, and regenerative abilities are as well developed as those of any living undead. He also inherited the thirst for blood from them, which periodically awakens in D, but he successfully suppresses these urges, except in cases where it can help him complete a mission. Despite the contempt and hatred that people feel for him, he continues to help them, and not only for the money they pay him. D is always true to his promises, no matter to whom they are given.
By the way, the setting is quite unusual. Devoted fans of "canonical fantasy" or post-apocalyptic settings like Fallout probably won't like it.
