Then Marcia feels a pain in her foot as one of the beast girls accidentally stomped on her.
This made marcia realize that this was how the girls disappeared all the time. Also knew she wouldn't be of much help if the people behind this found her, so she left the transforming girls (which were now much more worried about their changes to notice) and started to run while seeking a place to hide and wait.
While running she noticed that, although she has been exposed to everything the other girls had, she wasnt changing. Perphaps she was inmune, or it was slow on her, whatever the reason was she was save, for now.
What will she do?
