I think Krystal has discovered a very obvious market niche that Sakura, Haylee, and Lyra kinda-sorta were the only players in. "Mystery Girls" and AMPs - you really never know who you're going to get. Here...you know.
Now, how soon before they realize they can add another $50-$100 to the price to properly position themselves between "Mystery Girls"/AMP (low-end), Skarura/Haylee/Lyra (higher end) and thus end up in the pretty-good-place-to-be middle-market position price-wise.
Ya sure, she may lose some clients that can only afford low-end but the price/volume and attracting more mid-/higher-clients may be worth it.
