The player, as the game's protagonist, receives the cursed "Diary of Faces" in an unmarked package. Upon seeing the first page through a dual-lensed variant of the "Camera Obscura" (the 3DS outer cameras), the player is taken into an old house. Maya encounters and stops the player from entering one of the doors, and they are brought out of the house and back into the player's world. Upon returning, Maya explains that the person beyond the door is the "Woman in Black", who takes the faces of people who become trapped by the diary. Maya and the player begin to investigate the diary, in order to discover its secrets and for Maya to regain her memory.
