Who is Namine a Nobody of?

[Tundra Saber]

This has been bothering me too. When i first got Kingdom Hearts II i always thought Namine was Kairi's Nobody but when i beat the game and saw every cutscene and understood Kingdom Hearts II, I had a thought:idea: because Namine can't be Kairi's Nobody because the only way for a Nobody to be created is for a strong hearted person turn into a heartless right? and Kairi never turned into a Heartless right so Who is Namine a Nobody of?

 

[Souretsu Gear]

Might as well explain. Even though Kairi never became a heartless, her heart was seperated from her body.
