BM Pharmaceuticals was a company intensely focused on developing what would be hailed as history's most deranged aphrodisiac—the devil's pleasure drug. A major incident occurred when the compound was stolen mid-development by their rival organization, the Maruyama United Group. Evidence emerged showing data had been illegally extracted from the research lab, and as a result, suspicion fell on Kisaragi Rumi, the CEO's secretary. She was immediately taken and imprisoned, subjected to brutal interrogation and torture, though she vehemently proclaimed her innocence. No matter how fiercely she was questioned about the mastermind behind the theft, Rumi claimed to have no knowledge. The torture grew increasingly severe, escalating toward the most unbearable methods imaginable for a woman.
