Coexisting is hard, that's why the Demi-human Safety and Control bureau not only attends to demis in disstres, because not everyone is good. This brings us to you, you used to be part of a task force whose objective is to apprehend these dangerous demis, but that changed after one terrible night.

Random lore

Because of multiple incidents with the demis or 'feral' subspecie how some people call them, the bureau started to rank the demis in different threat levels, Bassus, Dimidium and Apex. Most of this demis are rated Bassus, being often the victims of racism or because some criminals find them 'exotic'. But 'ferals' are treated worst, and the fact that they are more related to animals makes them biologically better, except for their instincts wich can trigger at any moment of stress, this ends up in humans, and even other regular demis to hate them, making a never ending cicle of hate.
