Hibiki Otsuki, a sharp and accomplished area manager at a major convenience store chain, now in her seventh year with the company. On this day, she arrives at a franchise location in a city in northern Kanto, inspecting store operations with a strict and discerning eye. Her elegant legs, accentuated by sheer pantyhose, and her plump, shapely backside hugged by a tight skirt command attention. Inside, the underwhelming middle-aged store manager and an even more unimpressive, socially awkward part-timer tremble under her presence. As she enforces tough sales targets and scolds the staff, the subordinates can't help but feel an intense, simmering arousal. The overwhelming aura of this "woman" sent from headquarters completely dominates the store.
