Experienced AV fans should know that back in December last year, a sub-brand of "SOD" was discontinued, and that was "Seishun Jidai"! "Seishun Jidai" has been around since 2015, nurturing quite a few stars along the way, like "Toda Makoto" who went straight to "SODStar," or "Matsumoto Ichika," the former content machine who dominated the "FANZA" streaming charts—they're both top-tier actresses in the industry now, which shows the brand had a keen eye for talent. Plus, from the name "Seishun Jidai," it's easy to guess that they specialized in the youthful schoolgirl vibe, with a strong emphasis on that fresh, innocent style. Their works usually feature raw, natural performances, bright and clean compositions with lighting and backgrounds designed to transport you back to your teenage years, reliving the sweet and sour feelings of that awkward first love. Some might say it's no surprise for "SOD" to create a bunch of sub-brands and then quickly shelve them—that's been their thing for ages! But what's different here is that "Seishun Jidai" had been with us for nine years... So, unlike other brands, "SOD" didn't actually end "Seishun Jidai"; they just rebranded it, changing the trademark and title while keeping the numbering system going, operating it in a new form. The new brand is called "Mebae 18," which not only strengthens the essence of "Seishun Jidai" but also adds an "18-year-old only" restriction on top of the existing school uniform elements, aiming to be the industry's first of its kind! You've got to hand it to "SOD" for being bold and innovative—I'm saying that because when the new AV laws were about to be announced, everyone in the industry quietly agreed to claim all their actresses were 20 and up, playing it safe. But even before the official rules allowed 18-year-olds to perform, "Mebae 18" is declaring all their girls are 18, so you don't need to take it too seriously. As for the very first leading lady under this revamped brand? It's "Natsuno Chinami," who's over 170 cm tall and was on the track and field team in school: Just look at the cover, and you'll see she's a "track and field girl"—straight out of the sports club, this beautiful young woman has a slender, tall figure with a healthy, sun-kissed wheat-colored skin that screams vitality. Especially those straight, long, gorgeous legs—leg enthusiasts, don't miss out! And she's just turned 18 with only one sexual partner under her belt, making her a total newbie. But that's the fun of this industry; even inexperience can be a selling point. A lot of people love watching a girl get all flustered and overwhelmed by the male actor, and everyone gets a kick out of hearing her squeal. On the flip side, if she suddenly goes wild and rides him hard in cowgirl position, that's awesome too. Whether it's her "shy and underdeveloped" demeanor or her "instinctual reactions" during intense scenes, it all works as a draw—especially when they hype up her having just one partner, you know the focus is on her reactions in bed, so feel free to pay close attention! As for whether Natsuno Chinami is top-quality, I'd say it's subjective and has its merits. If you're into curvier types, you'll probably pass, but if you like the slim, athletic build, you'll eat it up. One thing I can say for sure is that seeing Natsuno Chinami took me right back to my clueless teenage days, like a summer afternoon when I was walking with my best buddy to that rundown, pothole-filled asphalt court, passing by the track field where a sweaty senior was sprinting the 100 meters, and the air was still fresh from the rain—it was all so perfect! Plus, in the trailer for "Mebae 18," they spent a lot of time zooming in on this newcomer's looks. What about you? How do you feel about this debut work from the new brand "Mebae 18"? Is it a pass or what?
