Who has better stuff?

Hikki - better skin, fashion/style, sometimes hair.
Ayu - better teeth, sometimes hair.

I think there's no contest here , Ayu wins in all. (except skin color , since I really don't know what to say to that one lol)

I think Hikki really often looks kinda plain and her hair/fashion never seems to be that impressive.

Ayu does have a cute gap in her teeth though ^_^

No, she doesn't. Nor are her teeth perfectly straight. If you look at this picture below, (thanks, Zyrex) you can see that her right front tooth sticks out just a bit. Sometimes this creates a shadow and makes it appear that there's a gap...but there isn't.

I like Ayu's style better... but I love Hikki's "normalness". Her imperfections make me relate a lot to her much more than Ayu. In other words, I like both for different reasons
