( Spoilers ahead! )
The thing I love about Attack on titan is apparent equality of females in the AoT universe; they do seem to occupy traditional roles too (e.g. Eren’s and Jean’s mothers) but they get to train and fight equally alongside men. Ok, so there are more men in ruling positions (is there even a queen?), most characters are male and the religion seems to be a purely masculine domain, but there is a big number of women/girls in the military which is traditionally a male domain.
There are girls there that literally kick ass.
However, no matter how strong the female character may be, there always seems to be a male figure behind her, as if she couldn’t stand on her own or be the creator of her own success.
