Mother Possessed by Obscene Runes: Alicia

A kingdom suffers from supernatural possession by creatures called "evil spirits" that steal human reason. The protagonist Alicia serves as a priest in a mountain village church. After exorcising an evil spirit that manifests in the church, a mysterious mark appears on her lower abdomen—a curse called the "lust mark," inflicted by evil spirits to counter holy practitioners like her. The curse reacts to the victim's deepest desires and gradually erodes their rationality. Alicia, who has long suppressed an bottomless sexual appetite through sheer willpower, must confront what she becomes as the curse takes hold.
