Apart from the obvious ones, like Yuma Asami and Yua Aida, I will list some of my personal faves.
I was obsessed with Yua Kisaki during her time in JAV. Had all the attributes I liked, pretty, knows her to bang and looks cute as hell with girl next door looks. I want her back really bad.
China Miyu, left way too soon, cute and sexy, would like to see her experiment with other labels.
Honoka, 100% pure woman to me. Sensual and classy, just would like to see her perform and branch out, in this current climate, maybe Prestige for example.
