Late at night, AD Takeshi Terauchi stares at images of gravure idols on his computer screen. Just as he begins thinking about masturbating, a mysterious message appears: "Free samples of possession-enabled pills available now." Out of curiosity, Takeshi registers, and a few days later, a sample arrives in his mailbox. That evening, Takeshi is working on a shoot where producer Matsuda, nicknamed "Pii-Matsu," is in charge—a man known for hitting on models and treating assistant directors like trash, making him widely disliked. This time, his target is Maiyuki-chan, a popular new gravure idol who's gaining attention at her agency. In Maiyuki's dressing room, Pii-Matsu's misconduct begins. Despite having made no plans to eat together after work, he suddenly approaches her manager, Saki, making unwanted advances. Ignoring Saki's obvious discomfort, he continues crossing every boundary. When Pii-Matsu sulks after being rejected, he shifts his target to Saki herself. At that moment, Takeshi's mischievous impulse erupts. He gulps down the entire dose of the possession-enabled pill. Suddenly, a presence—distinct from his usual self—seamlessly detaches from his body. Now, it's time to enjoy himself to the fullest!
