Just in case you didn’t know who Rise was, Atlus released a couple of new character videos covering the main cast of Persona 4: The Golden. There’s something interesting about the protagonist’s clip, which is from the very beginning of the game. Watch it and see if you notice anything interesting…
… Did you catch it?
At the very end, the Hero, Nanako, and Dojima walk to the car, but a "mysterious" girl with striped stockings passes the protagonist in Persona 4: The Golden. All three characters go straight to the car in Shin Megami Tensei: Persona 4.
It looks like players will meet Marie, a new character just for the PlayStation Vita version, pretty early in the game.
