In the universe, they were selected by the universe and became so-called examiners.
Examiners are always very busy and need to travel from one world to another, immersing themselves in local civilization while searching for similar species.
Of course, the opposite of the civilized examiners are the "reapers". There are 14 reapers, carrying the entropy of the universe. The 13 civilized examiners are the beauty of the universe. Of course, some are "reapers" and civilized examiners at the same time.
No one knows for what purpose the examiners were selected. So far, the lives of 27 people have been intertwined to form a complete "circle."
As the first point, Akarinya followed the will of the universe and began the screening.
