Very well, let's place the long and short of it in here.

Once upon a time, a human (namely me) came to the world of Equos. Upon arrival, they failed to understand their situation. And just like that things started to turn into a twisted version of what he believed to be a happy fantasy world.

As it turns out, the reality is far crueler than fantasy, who would have thought? Also, who the hell wrought a guide on humans and slammed "disease-free" on the first chapter?
