Fornicatio, also known as the Deadly Sin of Lust, is a major character in the story, "High School DxD: Nanatsu no Taizai." She is a member of the Seven Deadly Sins, and one of the four surviving members that survived the aftermath of the Great War. As a member of the SDS, Fornicatio possesses a great deal of power, and is one of the more powerful members. She has also taken up the role of being an idol, acting under the stage name, Luxuria, and is known for her techno-retro shows and songs relating to the Seven Deadly Sins, perhaps out of memory for her fallen comrades.
