Host: (reading fan question) "Cidney-tan."Tabata: I'm sorry, what am I supposed to answer there?
Host: Well, just who is she?
Tabata: Ah. Well, her name is "Cid"-ney, so that should give you an idea. But in terms of who she is to the player, well, she isn't integral to the story, rather she's integral to the player's adventure – she's a mechanic who supports your travels. What she works on, you can probably guess [from the trailer]
Host: That's who she is.

I do speak Japanese, by the way. Not that this would exclude a mistake but the director mentioning it and me understanding her name and seeing a picture where her name is written should be convincing. Shidonii has nothing to do with Cindy. Shi = Shi or Si, do = do or d, nii = n + long pronounced i = Cidney.
