Intro. Gachiakuta takes place in a dystopian world where there exists a floating country-sized structure known as the Sphere , which runs on a social caste system that divides the rich and wealthy society from the poor "tribesfolk"—descended from notorious criminals and exiled by the upper-class—by way of a heavily-guarded wall. Both sides of the caste dump their trash and unwanted waste, as well as people convicted of any crime, down the "Pit", a never-ending expanses below the Sphere in which the Spherites —the inhabitants of the Sphere—deemed inhospitable to all forms of life. Unbeknown to the Spherites, beyond the Pit and the "Border" separating it from the Sphere lies the "Ground" , a lawless wasteland with a mostly toxic environment infested with the Spherites' waste due to the constant downpour of trash from the Sphere, its heavily polluted areas are often roamed about by Trash Beasts, living creatures literally made of trash, and givers specialized with handling odd objects.
