New edits:

Two pretty important edits have been made to clear up possible confusion, the first includes an extra sentence during Chapter 3's critical explanatory speech, which is highlighted in bold for the reader of this post's convenience:

The same is true of Wakaba, who is also Akane, and has memories from both lives equally inside of her.  Ditto for Sara and Himeno who remember both their London and Hatsunejima lives."  I explained.  Wakaba nodded, suddenly getting why she could remember growing up in two different places with two different names among two different families with a deep sense of relief.

The second edit involves the FF girls from earlier FF's, where the graphics were none too flattering.  I address this issue late in Chapter 24:

Aerith and Tifa were of course modeled after their beautiful Remake versions, just as Rosa and Rydia were modeled after their PSP Complete Collection opening fmv versions.  If she had still been the bunch of floating blocky rectangles from the original intimacy would have been a hurdle too high, even for me.

This after realizing Aruru uses 'Oto-san' instead of 'Odo-san' and correcting it just minutes ago.  The edits keep flying off the presses.
