Everything takes place in one of the worlds, or more precisely, in a desert with lots of rocks, sand, and monsters that attack only outsiders. Outsiders are creatures that can walk around the world, level up, and so on. But the monsters don't attack locals. There are also three known currencies: Eidos, Versiform, and Rice, which are used by both the inhabitants of the world and outsiders. Outsiders also use marbles, so to speak—a kind of coin that can be used to trade strength, will, intelligence, and other things. Marbles are very valuable to outsiders because they can level up and become physically stronger. Life is harder for locals because they can't level up with marbles and can't restore health and fractures through injections, which is why they are always careful and afraid of outsiders, as they often attack them and steal their resources. Also, locals have mines and they are often robbed by strangers and these mines are like licks of eidos, versiform, etc.
