Guess I'll just post more of her-- I've learned a lot since the last thread, well sort of.
Her name seems to be Umino Minami, 海乃みなみ. She is an underground idol but has seeprate twitter accounts for idol work vs her modeling. The modeling account is @minami_taya on Twitter. She's also active on Fantia and as a cosplayer, with her gravure/portrait work being more recent especially after joining the Fresh Photo Session this year.

Anyway, I think she's incredibly hot and cute so hopefully she makes it big.
