Based on the novel by Ei Takatori, the series comprises two episodes. The story begins in 1212 AD during the Crusades, where an innocent soldier, betrayed, leaps to his death, vowing to return as a fallen angel. Reborn in the present day as a woman named Aiko, the soldier rises as the military leader of a new crusade, unifying the world and abolishing religion. Haunted by past-life memories, Aiko travels back in time, finding herself in a battle to save the future. Known for its provocative content, "Sins of the Sisters" includes explicit sexual and violent scenes, advising viewer discretion. The OVA received an English dub in 2000, distributed by Central Park Media. The series follows Aiko and her companions as they travel through time, battling against religious oppression and trying to alter history, all while incorporating graphic depictions of sex and violence.
