Beautiful new female employees Airi and Himari accidentally ingest an experimental drug while competing for their desired job placements, turning them into trial subjects in an outrageous, chaotic catfight. Victory means assignment to their preferred department, but defeat condemns them to become full-fledged test subjects for the abnormal drug. A desperate battle with everything at stake begins. The drug induces five distinct states: involuntary physical movement forcing them into combat, violent aggression leading to brutal beatings, extreme timidity causing fainting from minor stimuli, heightened sexual arousal intensifying their fierce struggle, and complete mental breakdown resulting in a perverted, inhuman brawl. Driven by the drug's effects and their burning desire to win, their clash spirals into utter destruction.
