too bad about that... they should make the delisting rule for the actress not the persona.
Her Shion movies were her best for me personally because she had the slim fit body in addition to the big boobs. And her passive acting could be attributed to innocence or inexperience rather than just lack of effort like now.
There are other examples of the delisting "rule“ mis-applied or mis-used. For anyone as successful as RION the rules are often bent. Conversely for small fries, often one finds the rules can be bent against you.
I find her "inexperience" and/or "lack of effort" kinda charming in a way. But definitely she is getting rather fat over the years.
"she went on long breaks from this for no apparent reasons"
Maybe she has personal issues to deal with? Not sure why this article is so negative about how someone decides to manage their work/life balance.
Indeed many idols take breaks for various reasons, some are disclosed, others are secretive (roughly half/half?). But Shion/RION/Rara's breaks (current count stands at 3) are pretty unique. One feature is she/her agency/her studio kinda go out of their way to NOT answer fan's curiosity. Typically idols who didn't want to disclose her reasons would still at least offer some polite (but non-informative) words. Lack of polite words, especially when she returns to JAV ("revival") with or without a name-change, is pretty unusual for Japanese culture. Another feature is a kind of "trolling" of fan's intelligence: twice her return was branded as "debut" instead of "revival". "RION" even explicitly deny being the same person as "Shion" in her "debut" video, yes we are used to suspension of disbelief (esp. with creampie, hidden camera, incest, one month celibacy... (a long long list) etc) but an outright bald factual lie, that's extremely rare in Japanese culture. Of course we take it in humor. And for her most recent break, the powers-that-be even denied there was a break at all.
Of course I remain a huge fan despite her unprofessionalism, perhaps even because of it.
