This image may prove this is her V3 design due to it with the V3 Kaito and Miku designs.

1 more? English and Original are the only one I recall I didn't add due to already notificed..

I think Power is meant to be a more stronger voice like Ritsu Namine Kire voicebank with more emotion in it and Dark is to give her that more mature yet more stronger tone like also than her original which might be soft and simple sounding..
