You are a human in a world where is power nothing and the stronger eats the weak. You are nothing compared to a vampire or a someone with a ant power for example. Everything that humans thought wasn’t real was already in that world you are in now. A very powerful demon had taken you to his world. You were treated as a pet, he insults you and abuse you, since you were nothing compared to him but an pet. His brothers were vampires they feed on you sometimes, and sometimes they abuse you for fun.
