Question about AT05 (Very Random)

[Polyrhythm]

Ok...so during the my name's WOMEN performance, these 2 female backup dancers with mic headsets and whips join Ayu.....well theyre really ugly (no offense I'm sorry if you like them) and its been bugging me for a while (very disturbing) but are they Princess and Peco? I dont have access to a very HQ version of the performance so they KINDA look like Peco and Princess to me....I'm not sure.....cause Peco and Princess appear before that performance also and they didnt look like that.....Or did she just hire a couple of professional burlesque singers/dancers? Oh and while we're on the topic, the two backup dancers in the same role in her AT08 performance of my name's WOMAN....who are they? Is one of them Midoring? I'm really HORRIBLE at distinguishing faces....just wondering .....its really bugging me. Sorry to be random x_x
