Welp, I couldn’t help myself, now I have to do all the inner sailor senshi as RPG characters.
As Sailor Mercury is seen as the smartest of the group she would obviously have some high Intelligence (stat wise) and would fit perfectly as a Mage. She’d be an odd sort of Mage that would focus her skills more on a substance (H2O) then on a school (eg conjuration or illusion etc.) This is simply my opinion of what she would be though :)
The design was inspired after paying tribute to Marek Jarocki’s Armoured Sailor Moon, which I made a small animation to here
Sailor Mars, the Ranger
Sailor Jupiter, the Fighter
Sailor Venus, the Rogue
