There are three races in the world: gods, humans and demons living in the world of gods, humans and demons respectively.
Races that were originally strangers to each other, by chance, the gods and demons opened the way to the human world. The gods guided humans, and the demons induced humans. The gods and demons spent a lot of time understanding the characteristics of humans, and at the same time, they sacrificed many tribesmen.
Just because humans have "wisdom" that neither race has - creativity, but this "wisdom" has also brought a lot of trouble to humans themselves, such as war, greed, jealousy, desire... Etc., Which has caused endless troubles to the two races.
After a certain demon who was too full and too idle went to the human world for a while, he suddenly had a whim, posted a notice in the demon world, and summoned his fellow demons to establish an office together. The one who convinced most of the tribesmen did everything personally during the process of establishing the office. His reputation in the demon world gradually increased, and the number of members in the office increased day by day, forming an indispensable bridge between the demons and humans. The person who later became the director known to the members strictly abides by the rules set by the director.
That office was also named, "Devil's Office"
——Remembered in a secret repository in the human world
Dan'er (tilts head): Director, it's written by a human being. Is it really okay to have a watery introduction? Obviously we are——Hmm (mouth covered)
Director (covering Dan'er's mouth with his hand): 13 blocks is high enough, who cares.
