Haunting Ground, known as Demento in Japan, is a survival horror video game developed and published by Capcom for the PlayStation 2 console in 2005. The game shares many similarities with Clock Tower 3.

The player-character and protagonist of Demento is eighteen-year-old Fiona Belli, who before the start of the game was involved in a car accident that killed her parents. Although Fiona is not very athletic, she makes up for this with her quick mind. She rescues and befriends a white German Shepherd named Hewie. Throughout her exploration of the castle, she encounters several characters: Debilitas, a large, mentally disabled man who works as the gardener for the castle; Daniella, an homunculus unable to taste, feel pain or pleasure who cooks and does the household work around the castle; Riccardo, the castle's groundskeeper; and mysterious Lorenzo Aureolus Belli who seems to want to help Fiona.
