Persona 5 Scramble: The Phantom Strikers is coming to Switch and PS4 in Japan REAL soon (Feb. 20th to be exact), but fans can get a glimpse into the game right now. The demo is available on the PlayStation Store and Nintendo eShop in Japan, where you can play the first hour of the game as Joker. You cannot transfer the save to the full version of the game.
