My problem is with the heroin being a total stereotype.
The heroin is more tall and full of T that any other boy in the manga. Boys and girls have same size hands except the heroin : Giant hands. Everything is made to underline the 'she cant pass' feeling.
I've been a lesbian transgirl for years and I didnt always pass. I know very well those 'allies' who fantasize over our virile body in dresses. They say they get you and their views are OK, but when you dig under the surface, you always find a woman fantasizing over feminine men in dresses. They like the male they see in you and they want to make it lovable. It's somewhat disgusting.
I have dozens of tgirls friends of all ages. None of them look like Akira.
And a lot of them dont pass. Thats not the point.
