How Noel rm interview went when she audition for "Shirogane Noel":
>So you want to become our Shirogane Noel? What makes you think you are fit for it?
>I have big tits.
>You're hired.

So do you think they also take into account your physique during audition? I'm not talking about breast size of course, I'm talking about stuff like Height and width. Since considering stuff like 3d model and motion capture, it would looks pretty jaring and glitchy if their physique is vastly different from their model.
