She desires Soos Ramirez.
Giffany is featured in the episode, "Soos and the Real Girl". She is a parody of girls from Japanese dating sim games. During her development, her creators found something wrong with her programming. When they tried to delete her, she retaliated by killing them. Before Soos, she had a history of becoming possessive of previous players, which scared them and resulted in them returning her game.
Giffany tends to become attached to whoever plays her game, genuinely believing that the player is her boyfriend. She normally acts nice toward them and aids them if they have never played a romance game before. When he isn't spending time interacting with her through the game, she stalks her "boyfriend" through electrical cables. During a confrontation with Soos who tries to end the relationship, she becomes quite possessive and angry that he found another girl. In an attempt to have him all to herself, she follows him and plans to kill his friends and his date unless he agreed to be downloaded into the game with Giffany. She also attempts to break him emotionally by telling him that no other girl except her would love Soos.
