I'm not sure if anyone noticed but ever since the miss fantasica contest, there appeared to be a pattern with the 5 maidens which a distinct style. However, I noticed a new kind of pattern that may appear again in the future.
Notice all that circly thing that glows. They all have that in common... What does it mean? My theory is this, that there may be a 'kids' contest or something. Have you noticed any other units with a pattern that are from different events.
