The eerie ability of Kurusu Hiyori, daughter of a former police chief, is to predict murders in her dreams. Her first prediction was that of her father's death, leading to isolation, a macabre reputation, and work complications due to her inclination to investigate incidents before they happen. Furthermore, her dreams have resulted in adult bedwetting and a reputation of failing to prevent deaths.
However, everything changes when Hiyori dreams about the assassination of Claus Haida, a foreigner whose death she prevents. Despite the initial elation, Hiyori discovers that Claus is a monster who serves a foreign company, promoting teamwork with questionable intentions. Is she capable of collaborating with him?
Volume 4 also features the one-shot "Akumu Imouto! Umaru-chan."
