In the game's story, there is a hidden time known as the "Dark Hour" that exists between one day and the next when all movement in the town stops. During this time, terrible creatures called Shadows roam, and a group of high school students in the city of Iwatodai are drawn into the Dark Hour to fight these creatures and explore the mysterious tower of Tartarus. This group uses weapons called Evokers that are used to summon Personas.
