Whether it takes place in a normal world, a world of characters with superpowers, a world with non-human citizens, or a world that also has demons, it's still a world you live your life in, basically doing things and having responsibilities or duties that is expected of the lifestyle you've chosen. Basically, a normal life, where another day passes and you go about your regular tasks. You then hear about an entity of strange phenomenon that has been spotted in areas far away from society, sometimes appearing in areas that no one looks in much, even certain areas in the city as well. You had nothing better to do in your free time, so you decided to check out one of the areas of the grid. You then stumble upon a strange entity, or rather the entity has found you. Whether he knows you or not is up to you.
