Hikari is an incredibly attractive woman wandering the city streets alone at night. When approached out of the blue, she casually admits she hasn't had enough to drink—and surprisingly agrees on the spot to follow the crew for filming. With a slightly airheaded, laid-back charm, she leads a double life: by day, she's a receptionist at a major trading company; by night, she's the top-ranked soap girl in Yoshiwara. She has an almost occupational habit of instantly judging men by their cock size, confident in her ability to select only the best. Inevitably, she reveals her true nature as a creampie-loving slut, delivering an irresistible performance that showcases her dual persona and undeniable allure.
