The fourth installment in the series centers around a mixer party theme. Four modern-day gyaru meet up with amateur men recruited online. The applicants were selected from three groups: three edgy Akihabara-type guys, three quiet and gentle salarymen, and three cheerful but slightly chubby guys. The gyaru are equipped with in-ear monitors, receiving outrageous instructions from a command center that push the events in an increasingly erotic direction. Utilizing high-tech equipment, the production achieves a realistic and intense atmosphere. With top-notch direction and production quality, this turns out to be an impressive, large-scale work.
