This is probably just a stylistic issue, but anyone have an explanation for the variety in the compact?


This is the first time I've seen Mar's stone present on the compact as pictured on the second image at the top. For some reason or another it's usually nor present, or perhaps it's Venus' which is missing. Any theories?

It's probably a continuity error or the animators in the anime decided to take some artistic liberty and change the design slightly.

True, but the same thing seems to be the case with distinct manga adaptations.

I have a theory of how it reflects Usagi's relationship to the senshi (and by extension ChibiUsa and her guard), so I always found it curious. 

Perhaps it was a bit premature to introduce the Cosmic Heart Compact before the introduction of the Outers?
