But c'mon man, Rara Anzai is a unique case because she's insane. She has what, three retirements in eight or nine years?
The industry is relatively big and has a high turnover rate, so whatever trend you seek, you'll find it: actresses with ten-plus years of career, five years, three years (there even were two good friends who retired after three years, one in December and the other in January).
If the fear is about her outgrowing the industry, then you can look at similar examples, but even then it's hard. The closest in terms of "insane popularity for a rookie" would be Yua Mikami, maybe? But even then, Mikami already had a big name (for good and bad) before joining the industry, so in a way, she was already big enough and still gave it eight good years.
You can try to "predict" by looking at her brand outside of being a "JAV Idol". Here are some comparable cases just to point out how different things can be:
- MINAMO: Not comparable in raw numbers, but if you scale for the size of the studio she's exclusive to, then yeah. She's retiring at the end of the year :sadKEK: making it a five-year run. She's probably the most unique "idol" in the industry (very hard, if not impossible to find a replacement). If you go by the idea of "making a name outside of the industry", she could've easily retired after one or two years.
- Yotsuha Kominato: Same studio as MINAMO, and also had a background (not as big as Yua Mikami, but respectable). She's in her fourth year, granted she has a condition that made her reduce her shoots and eventually go on a small hiatus. But the thing is that she moved away from what she was known for and started doing theater, now she's been in a bunch of plays and said she's back to shooting. Who knows if she's back for a "Last Dance" or back for good (SOD will need a new ace, though those lucky bastards :FeelsRageMan: might have already found one, even if they fucked up an excellent prospect). Point being, she could've been retired by now.
- Ayaka Kawakita: Might be the best example since she's also from S1. This is the fifth year since she came back, and everyone (me included) assumed she would be long retired by now, given she made quite a name for herself all over East Asia. And look at her still going, people don't even remember her scandal :leokek:
Anyway, my point is that there's no way of knowing what's next, and it's not even just a JAV thing, it's a Japan thing. Kanna is too new to be affected by the 2022 Law. She could move to Doujin, but she's in the biggest studio and it's not like she has to do crazy stuff. She's heavily promoted by S1 and BStar, for the last TRE, she was promoted just as much as Ayaka (that photo of them together got 38k likes). The studio and her agency are doing their part, but again, it's a japanese industry, you never actually know what's next.
