She would indeed suit the group and actually i don't really see her going anywhere else (except the new group since they don't have a concept yet). MM is packed full and she is old enough not to wait until someone opt out to get in, J=J is a no-no because she is pretty much an Akari doppleganger (Don't beat me for this, to me she is pretty much a "prettier Akari"...), BEYOOOOONDS is not generation oriented so far, TF could be a nice fit but they just received young and fresh members so unlikely. Actually, she would prefectly replace the mature looks of Kassa in Ange.
I could definitly see her becoming a model, her looks are no joke.
Honestly, if she doesn't leave by herself, I don't see management passing on her. She's too precious for the agency IMO.
BTW, how has she been received by the Japanese audience recently, does anybody knows? I feel like she has acquired some visibily lately, is she popular?
