Based on the rare personal experience of actually having been choked to the point of death, two beautiful lawyers passionate about the study of pleasure, Mizuna and Yui, investigate past choking incidents and conduct real experiments to meticulously analyze the psychological state and physical reactions of the choked subjects. Using their bare hands, gloves, cords, ropes, and even hair, they perform choking acts, deeply exploring the expressions and responses of the victims as well as the emotions and mental states of the chokers. The experiments proceed until the subjects roll their eyes back and lose consciousness, offering an unprecedented, experimental, and daring form of entertainment from a completely new perspective.
