Not sure if this is official or a final version yet, but like Hatsune Miku and a few other PS Vita titles, Gust's Surge Concerto will get a slick screen protector to defend your touchscreen and add a little style to the gaming experience.
There are also the matching screen backgrounds you can grab from the official site right now. Hope these neat gimmicks make it across to western versions (although guess you can't fold them in the dinky cases).
The latest update on the game's progress in Japan from Famitsu unveils the rather slinky shopkeeper from the grocers. She's a bit of a free spirit and a mischief maker, although I'd do anything to liven my day if I had to stand behind the counter all day in those shoes. Don't developers ever think of the practical side?
