Ummm what? Akane is a girl Aoi is a boy so I'm really confusedwith your comment

Are you sleepy...the twins is boy and girl y know hahahahahaha (〜￣△￣)〜

Ahaahaahah I know!! But Aoi was sweet and delicate like a girl and Akane was loud and direct like a boy!

I don't think so, their personalities are a lot like my brother and myself. He was more calm and collected as a kid and I was loud and always spoke my mind.

And why should make a difference in my opinion? There are some characteristics that are ying and others that are yan, I really can't understand why this is so wrong. I would liked to see a different type of girl and a different type of boy, like they were by little ones

Characteristics aren't gender specific is my point, you shouldn't say they don't fit their gender because of how they act.

Omg I talked about ying and yang, if this was difficult to interpreter. There are somethings typically ying (and girly) and some typically yang (and boysh). You can have a boy with a lot of ying and viceversa. For example a nurse should have many ying characteristics, but it doesn't mean a girl have that and a boy not.
Plus, there are hormones that can modified a personality and brain, so a boy tends to have some behaviour, and a girl others. All that is from my studies, they aren't my opinion.
Well I would like to see an Akane not so interested in love like a topical girl, and an Aoi not so cold like a typical boy. I really don't know how to express it any better
