Thats literally just a disheveled tatsuya. Which makes sense given the horror theming that the trailer had, persona 6 could be a return to the series roots. I'm calling it now, 3, 4, and 5 all merely took place in the timeline that tatsuya saved at the end of P2EP, and the new game is somehow gonna tie into that, or at the very least make a callback.
