Kana is now Kanna in the WWE

Well on August 22, 2015, Kanako Urai (better known to us as Kana) showed up on TV in the crowd at WWE's NXT TakeOver: Brooklyn event in Brooklyn, New York.
She was with Sgt. Slaughter and Ric Flair and was identified onscreen as "Kanna".
Five days later on August 27, the WWE indeed confirmed that she had signed with them a few weeks earlier.

So is she a Diva or a trainer?
Trainer would be awesome for the Divas and I bet that Kanna could still work matches for other promotions.
I just don't see Kanna as a WWE Diva, considering she could take out 90% of the roster by herself.
