Amanda is currently in room 1C i believe. i last saw her there earlier this month. previously she was in room 1F (with a sign that said ”168cm model“). this old review of her that's basically accurate. good attitude with a relatively tall and fit body.

Luna is in room 1G normally, but i've seen her in other rooms on the 1st floor including 1H. she has medium length dyed hair, d-cups and generally wearing bikini. sweet girl, but her hip/ass is a bit too small for my taste.
KK is in room 8F. she does mostly booking, but if u go at off peak hours, might get a walk-in. can't miss those massive overflowing knockers. prob largest in KB. all the while rest of her body are still slim.
to be clear, these are just the ones i tried that i think still worth 700 asking price at KB. i am sure there are others. love to hear other recommendations.
