The story focuses on Arata Shindou and Kei Mikhail Ignatov, two rookie inspectors from the Ministry of Welfare's Public Safety Bureau (MWPSB). These two inspectors face an ever-changing society governed by the all-knowing and impartial collective consciousness system known as Sibyl, alongside a contradiction that exists solely to highlight the imperfections of the Sibyl system. Dealing with rising anti-immigrant sentiment, political intrigue, and peculiar individuals who exist solely to test the Sibyl system, these two inspectors are presented with two choices: to either follow or overturn the system.
