Atlus has been very active lately in releasing gameplay video of their upcoming game, Persona 5. The most recent was the Morgan Bus video wherein one of the characters in the game turned into cat bus. I assume that they are paying homage to the popular Studio Ghibli movie My Neighbor Totoro.
Now, Atlus is now releasing a video of Personas of each of the characters in game in action. Persona is one of the most powerful attack of a character in Persona game and think of it as a counterpart of Summon in Final Fantasy game. (Check out the names of the Persona of each character of Persona 5 here.)
