Naida Davola

Naida Davola is a young homeless girl about ten years old who was adopted by the Davola family as a sort of maidservant when they realized she was homeless and hungry.

Profile
In her first appearance (Terror of the Zypedrians), Naida appears shortly before Christopher Davola is to be born, causing Daniel and Hannah Benfield to think that she is the Zypedrian who was sent back from 4246 to kill the child. In an effort to get more information, Hannah begins to develop a friendship with the young girl.

It turned out that Naida was not the Zypedrian (it had been disguised as Mr. Davola), and in fact was "completely and utterly normal – simply a victim of bad timing". Shortly after Daniel and Hannah walk into the TARDIS, Naida waves goodbye and prepares to walk back to her new home...but is suddenly pulled into the Ship.

"Contrary to what I had said, Naida was not normal – she wasn't even human. But that is another story."

Future
Among the many mysteries of Daniel's work is what Naida truly was and what happened to her. The first hint given regarding her fate was in the prologue of New Year's Eve: Azumanga Style, where she (now "Dr. Naida", the female Principal of Azumanga High) sets up special college courses due to a mysterious flame that caused the Azugirls to cease aging, which in turn got them thrown out of their respective colleges on suspicion of using drugs.

In The Reason Why, she is held prisoner by the Boss along with her beloved wife Nanami and daughter Nadimia. After being freed by Allura McCoy and Chrissie MaCockenshipiel, she is seen one last time in The Dreamer Wakes.
