Maplestory "secret story"

In Aran's case it takes a lot more than just somme shapewear.

Neither Aran's male face or female face have any hints of the opposite gender in them so you can say Aran can pass as both. Then you have the fact that male Aran's hair is really short and female Aran's is really long. And don't say a wig because it is obvious that female Aran's hair is real.

Pff, they're really chibified cartoon characters. I think it's fruitless to say whether something looks "real" in this style; it relies a lot on visual shortcuts and isn't meant for those kinds of distinctions. Let's not turn this into a rehash of the Demon Slayer thing with people measuring chibi skirts >_>
