Yume's voice is really similar to Rise Kujikawa from Persona 4 (English Dub). To put it into plain and simple terms, she's pretty much a genki girl most of the time, although she has sass (Ironically like Rise as well, the two share many similarities as far as personality goes). If need be, she can be seductive too depending on her host's wants (check out her character description to see what I mean)... Just like Rise- yeah I think you see what I mean here, her basic personality is pretty much just Rise.

Character Description:

"Hi, I'm Yume, and as I already said, I'm your dream girl!"

To some, she is 'always bubbly and playful, the only one who gives me the strength to look forward to tomorrow'. To others, she is 'the calm in this storm of madness, she is the companion I had always longed for'. To all, she is described as a woman of many hair colors. The consensus is that the color of her hair changes in accordance to her current emotion. 

Her over-the-top nature may be a bit strange in these unprecedented times, but even so, many find this attractive and thus she’s made many friends. All that being said, she seems to be someone who’s incredibly simple to figure out.

Despite the fact that a growing number of people swear by the existence of Yume, claiming to know her very well, only a handful of sightings have been reported thus far. This leads many experts to believe that those affected have gone mad, stating that they have merely created an imaginary friend in order to cope with their strenuous lifestyle. Still, can so many people really have such vivid and detailed hallucinations on such a frequent basis?
