Great article, Touka is one of the absolute best actresses working in the business today. Another title of hers that I recommend is CJOD-211 where she plays an escaped convict who breaks into a house and makes the xxxxx man who lives there her sex slave. It's a great video where she is sweaty 99% of the time and she is very domineering, so obviously it's a can't miss(in fact the whole series of these escaped prisoner titles is outstanding, and I give them my highest recommendation).
In Mika Sumire's defense, she did soapland and deriheru prior to doing AV, so it's only natural for her to be mentally detached during sex. Her aloofness didn't seem to drive away her customers, so she probably thinks if it ain't broke don't fix it.
