Postwar Tokyo lies in ruins, a chaotic battleground where a street prostitute named Mayu struggles to survive. After accidentally uncovering a dangerous secret, her life is put at risk. Ordered by the organization to eliminate her, an enforcer named Saeki is assigned to carry out the hit. Saeki has a unique method: when dealing with women, he drugs their drinks, renders them unconscious, then sexually assaults their helpless bodies—an abnormal ritual that plunges his victims into an indescribable state between heaven and hell, leaving them shattered by overwhelming shock.
