It's all shoko and yua past few months. Wonder if they'll wear off next year and more ex-idols will join. They don't need a scandal since a lot of idols are graduating too. Most gravure idols switch to av after their career hit a dead end, but not necessarily force to do it. I think shoko and yua won't last very long given their popularity, they can easily make enough to retired and go mainstream like sora, maria, and anri okita since they'll all busty.
not only them, chinami itou, aika, aki sasaki and other girls are working a lot in the past few months too
i'm sure more new girls will come to AV next year, some of them will be the next big star, and I don't care if they were ex idols or not, better if they are not, non ex idols or celebrities tend to perform much better
