Seikon no Aria

The Temptor’s Disease” is a condition in which the succubus’ curse causes the patient to experience uncontrollable sexual desire, ultimately transforming them into a terrifying monster. Only Aria, an exorcist chosen by the church, who has specialized in fighting this disease since birth, can save people suffering from it. As a child, the main character was attacked by an infected person who tried to rape and kill her, but she was saved by an “exorcist.” Ten years have passed, and the grown-up main character, Aria, decides to devote her life to saving people from the spreading disease of temptation.
