Within Mementos, Morgana suddenly loses control, and the Phantom Thieves find themselves within a mysterious town where they soon meet a new duo at a theater - the black-haired Nagi and white-haired Hikari. Much like the first Persona Q, the game features an Etrian Odyssey style of gameplay and dungeon mapping, and the Labyrinths in the game are worlds inside various movies at the theater.
