This episode's lead might not be familiar to many, but she actually has quite the background; she's the pioneer of "Ai Wei Wu Li." Not only does she have extensive experience, but her work count ranks 28th among all actresses, even surpassing Kimishima Mio and Tomoda Maki. Her co-star appearances are everywhere, making her seem like the easiest actress to work with. Unfortunately, with fewer job offers coming in, she's been on endless hiatuses— that's Mizuki Naoko. Mizuki Naoko was born in 1984 in Tokyo, Japan. She debuted in 2007 as an exclusive actress for S1. Honestly, if you just look at her on her own, Mizuki Naoko isn't exactly stunning, especially her face, which doesn't really fit the beauty standard. But she has this magical allure that's incredibly sexy, paired with an almost perfect body that stirs up primal urges after watching. Thanks to that sexiness, she started out as a gravure idol in 2005, achieved solid success, and then in 2006, released the famous gravure DVD "Ai Wei Wu Li." Now, "Ai Wei Wu Li" has become a standard for major newcomer debuts, so as its pioneer, Mizuki Naoko's title as the "first in Ai Wei Wu Li" holds significant historical value. In July 2007, she debuted as an exclusive actress for S1. Most S1 members are cute girls or model types, and Mizuki Naoko's rare H-cup perfectly filled their gap in the voluptuous category. During her year as an exclusive, she gained a lot of popularity. Side note, another popular actress who debuted the same year is Asuka Kirara. In 2008, she switched to MOODYZ, where she was exclusive for a year before becoming a freelance actress. Although her work volume shot up, an interesting phenomenon emerged: most of her jobs were co-star roles. Maybe it's because she's not only a great performer but also someone who's very considerate and easy to collaborate with. This led to a result where her film count is huge, ranking 28th on DMM's list of actresses with the most works, even beating out Kimishima Mio and Tomoda Maki. It's a really fascinating phenomenon. And as a side note, as a long-lasting actress, she once placed 22nd in a popular actress vote like the one for Ryu Ga Gotoku. As for Mizuki Naoko's dating rumors, her first experience happened after high school graduation, around 18 to 19 years old, which is relatively late compared to many others—that was surprising. Although she always had boyfriends, she had conservative views and always thought, "What if I get pregnant? My parents would cry; I absolutely can't do that." So, she kept rejecting her boyfriend's requests. Even if he couldn't hold back and wanted other ways to relieve himself, she stood firm and held out for three months straight. In the end, she finally let him have his way, which must have been a happy moment for him. Here's another fun fact to share: perhaps because she prefers slimmer guys, after debuting, she dated quite a few men who were on the smaller side. We often say that size doesn't determine pleasure, but it's hard not to compare with the male actors she works with. Even if Mizuki Naoko herself can brush it off with a laugh, her boyfriends might feel a bit insecure about it. Mizuki Naoko was active for over 12 years, a highly seasoned actress, but every career has its ups and downs. She's gone from being a top exclusive to hitting rock bottom, from a work machine with constant releases to now waiting for jobs—the taste of those role switches is probably something only she can truly understand. So, on January 1, 2020, she announced on Twitter that she'd be taking a long-term hiatus, and she's not even sure when she'll return—in other words, it's basically a retirement without a farewell work. Mizuki Naoko hopes to find a regular job afterward, but after rolling in the adult industry for so long, that's easier said than done. All we can do is thank her for all those years of hard work and quietly wish her the best.
