Interesting.................................So in the latin dub they somehow made clearer that seiya doesnt likes women clothes , i would like to see myself the true original version , since in the video i saw seiya didnt replied that , he just said , i dont feel like to.
I will start to talk in headcanon mode , since here since i dont wanna start controversy , but i think that if seiya really doesnt likes women clothes , that would mean that she doesnt likes her sailor uniform since is girly , she just wears it for obligation , but if she would have more clothe liberty , like civil haruke , then she would dress as a male , and not for some rescue princess stuff but because she really likes to.
and in that case i could consider seiya a trans man....................................but only seiya , not yaten or taiki.
but that would be just a headcanon based on that line , i am not saying that you should have the same opinion as me
