Despite her reputation for beauty and compassion as the daughter of an earl, Rosa harbored a dark obsession with "rose love" - a fictional romance between men - and sought to spread her perverse beliefs throughout the continent by becoming a nun and producing a "bible". She prepared for her future missionary work by bribing monasteries, improving literacy, and providing her territory with hummus to symbolically spread rot. However, her focus shifted when she encountered her half-brother, Bernard, whom she saw as the perfect submissive partner in a same-sex relationship. Determined to create her own "harem" featuring Bernard, Rosa's depraved actions were mistakenly seen as noble deeds by the upper echelons, leading to the spread of her corrupting influence across the country. Rosa, also known as the "Rose Angel" for her supposed kindness and generosity, was in reality the most deplorable and corrupt woman of all.
