The runtime.zip file contains 4 Aiko4 fits for SAV Zero (0) Gravity Hair. One is stock Aiko4, whilethe other three are geared for A4 Matilda, whose head is a little smaller. The 3 for Matilda include different forehead-hair lines in what I called Human, Elf, and Wolverine. It was actually hard to fit this hair to A4, as her head is wider and rounder than the stock model adjustments expect. However, given the nature of the wild 0-G hair, the fact that I ended up with high crowns isn't visible, and could even be considered a plus!
Requires you buy the stock hair here (I uploaded PZ2 pose files only!):
