Ai, who works in the Special Fraud Dedicated Section of the Investigation Division, was attempting to make contact with a “land shark” group that has recently been causing a stir. After working at a snack bar that the group uses for business negotiations for one month, she finally manages to get a lead. She is then proposed to infiltrate as the landlady of “Yukawaya,” an old-fashioned inn that the group is targeting, and begins an undercover investigation… A 10 billion yen case, a failure that absolutely cannot be allowed, but at the final stage of elucidating the whole picture, the developer who appeared before Ai as the buyer turned out to be none other than her own husband…












This is almost 2 hours long, but it's mostly foreplay. You don't even see Sayama Ai nude until after 20 minutes, and even then it's just a single bath scene. The drugging scene happens around the 32-minute mark – already a quarter of the way through! It finally feels like an AV after that, but the sex scenes become repetitive and hazy due to the drug. Sayama Ai looks gorgeous on the cover, and her figure is fantastic, but she feels a little *too* easily seduced as a detective.
Ai-san is getting more and more maturely sexy, she's so captivating! It's a shame she's retiring when her appeal is at its peak. This felt like a very directed, acted performance. I'd love to see some natural, unscripted erotic interactions. Let's hope the remaining releases deliver.
The thrill and excitement you get just from the story is what makes this genre so good. I especially appreciate how much detail they put into showing the month-long undercover operation – that alone deserves extra points. And I love the double-layered plot of her posing as the innkeeper. The director really gets what undercover investigations are all about. A lot of recent detective AVs skip over the undercover work and drama, but that makes a huge difference in immersion. Focusing on the drama and the undercover aspect might be a hassle for the production team, but it's a really thoughtful touch for fans of the genre. The actress's performance is also great, and her experience in this kind of role definitely shows.
Sayama Ai's nearing retirement, but she's really going all out! The contrast of her pale skin against the black set is stunning, and that back view is just insane.
