I'm a review whore (aren't all authors?
), so I might as well link my own Mai HiME story here. It's a relationship profile for Nao and Natsuki, taking place after the end of the series. Warnings for spoilers (duh).
Here it is.
Some people have mentioned that Nao feels a little out of character. I think that while that might a valid criticism, people need to keep in mind that the story takes place after summer break, so she's had a few months to mellow out and spend time with her mother. And plus, if I wrote for Nao strictly the way she was in the anime, the story would be all but unreadable.
