Not sure what happened there, but...

Even in "realistic" mode, Aiko isn't especially realistic, although there is a huge amount of very well designed material for her, so she is a good character to have..  If you use certain Poser-related applications, Aiko material, realistic or otherwise, can regularly fit Terai Yuki 2 at least as well as Aiko material fits Aiko "Realistic".   TY2 isn't any more realistic than Aiko, but TY2 looks miles better, with the RDNA morphs applied, and definitely has a markedly superior range of expressions to Aiko.
