Was likely that the artist didn't care too much about the size but if they end up getting bigger in the main manga then yeah she's getting fatter.
I think the idea of Lunarians having an estrus cycle is an interesting idea. Whilst non canon it could help at the very least make them a little more different (because in all honesty the only real difference in canon is lifespan) .

Either she will get outside help *cough* Chaldea *cough* or she will just have to get by with what she has on her......or Nasu has her use standard Fate magic somehow.
Lack Two/Colress didn’t even show up in Sun and Moon. Talk about wasted potential to flesh out our main character more with better writing and less time constraints.
