In a place beyond the jurisdiction of both the human and demon races, there is an independent space. A conspicuous sign stands on the right: Human-Demon Relations Office. Here, "human" and "demon" are simply clear and straightforward names for the two races. The Relations Office is a joint administrative agency established by the two races to promote long-term friendly cooperation. It mainly handles matters relating to interactions between the two races. Of course, this was merely an institution tentatively set up by the leaders of one generation after a major war, based on an idealistic vision. It may not even exist on the official books. The leaders in the following generations mostly chose to turn a blind eye to it.
