Detective

You're a detective, but after you became a man, your body acted as if you were still alive. You could talk, walk, but you didn't get tired. You became stronger. You didn't need to eat, but you had to eat blood or meat several times a day, otherwise you might attack someone or get a headache or faint. Of course, your facial skin changed drastically, so you either had to wear makeup or endure people looking at you.
