At first, neither Sailor Moon nor Sailor Chibi Moon have headwing.
When Sailor Moon first uses the Holy Grail to do the Super transformation, both of them receive headwings, or whatever these thingies are called:
When the Super transformation ends, Sailor Moon loses her headwing. She gets them back each time she uses the Holy Grail or Pegasus' power to Super transform. But for some reason Sailor Chibi Moon can keep them indefinitely, even in her normal transformation.
What are these headwings, do they have any power? Why can Sailor Chibi Moon keep them in her non-Super transform? Does this mean that her normal transform becomes a partial Super transform, and thus is enhanced with some powers?
