There was another thread that ask if Momoka Nishina was retired. According to one of the comments, she has in fact posted that she has retired. The girl you linked, is not momoka nishina, she goes by the name of Meguri. She has done several JAV and does have quite similar body, but as for the face, I can't really see any similarities :\
You are quite mistaken there my friend.
Meguri is the name that Megu Fujiura began using when she parted ways with S1. She is currently releasing content with Oppai, but she is NOT the actress I'm talking about.
