The female spy's identity was revealed and the ending was unexpected

Mizuki is an investigator who has conducted many investigations and all of them were successful. This time it's a mission to infiltrate an organization selling aphrodisiac oils. It seemed like a simple mission, but she was captured and detained by this gangster organization. What was waiting for her was intense sexual torture that she would probably never think about in her entire life. My sincere condolences to agent Mizuki Aiga.
