In a world where human thoughts, hopes, and imaginations can literally take physical form, two government employees work for a special agency known as the Correction Bureau. Daichi Hongou and Hisui Tenma are tasked with identifying and neutralizing the fictional realities that spring from urban legends, daydreams, and idle fantasies, restoring the real world to its proper state. Their cases range from bizarre to dangerous as they confront creatures and phenomena born from collective belief. Daichi is a straightforward, experienced agent, while Hisui is a sharp but somewhat enigmatic partner; their contrasting personalities create a dynamic that drives the story forward. One notable storyline involves a new urban legend about a man and woman carrying an attaché case, a rumor that eerily mirrors the pair themselves, forcing them to investigate a massive housing complex to uncover the source of the myth. The manga blends mystery, fantasy, and subtle horror as it explores the boundary between reality and the stories people tell.
