Second princess seems reasonable. Screw all that political maneuvering. But her depiction doesn't exactly scream "most beautiful princess." She looks quite a lot like the third prince, if anything.
They spend a lot of time explaining a plan that was rather obvious to begin with, although they did add the bit about the heir conflict.
Rei, Set, and Elena are an army of their own.
Still this lame censoring.
The fights scenes where Rei is involved are totally meaningless waste of pages.
Probably want to show them taking out the enemy so it doesn't come as a surprise that their forces are weakened. It's mostly about poor writing on a larger level, since while it might be a justification in itself, the fact that it's needed in the first place indicates that the entire plot needs restructuring.
