Pandora is the fortune telling doll owned by Aki. Hence the the name of the shop 'Pandora's Fortunes'.

While Kat and most of the other characters assume that Pandora is just a ventriloquist dummy, this is most likely false. There is heavy evidence in Gravity Rush 2 that it is actually equipped with mechanical elements that enable it to talk on its own, since Alias was able to hack into it to talk to Chaz using a mechanical voice, and it "breaks down" at the end of Gravity Rush 2, repeating a generic phrase about Raven's "lucky spot" that embarrasses Aki.
However, this alone does not explain why its predictions are always laser accurate. As one of the concept art pieces in the gallery of Gravity Rush Remastered shows a Nevi crawling out of Pandora, this could mean that Pandora is a Nevi controlled robot, similar to the Sea Anemone, and this is the reason it appears to have a mind of its own and supernatural powers. Following the events of Gravity Rush 2, the Nevi inside could have left or disappeared, leading it to revert to its original form as a basic mechanical doll.
