Watashi ga Seijo-sama wo Koroshimashita

The mysterious death of a beautiful saint has shaken the Kingdom of Faden. A young priestess with vacant eyes turns herself in, clutching the saint's severed head. "I killed the saint." In the interrogation room, filled with the smell of blood, Fiana of the Knights' Intelligence Department doubts the girl's words. How could a powerless child do that? Fiana's pursuit of the girl's secret leads her to a horrifying darkness lurking beneath the glamorous capital city, and to the "truth of the saint" that must never be touched.
