Kaibutsu Oujo S01E13 - Princess Sacrifice

During a lunar eclipse, the car breaks down when Hiro, Hime, and Flandre were on their way home. The three head down to a desolate village, but on the way there, Hime sprains her ankle when they are briefly met by a masked serial killer in the woods. Hiro and Hime are pulled into the past memory of Akasabi Village forty years ago. They gradually see that the village chief's wife, the director of the village, an unidentified person, and the village chief's son were reported missing and then supposedly murdered by the Paperbag Man of Akasabi Village. They also see silhouettes and hear voices coming from the villagers as well. The Paperbag Man, going against a dam project supported by the villagers, later committed arson and burned down the village. As the village begins to flood, Hiro and Hime head to the woods and see the Paperbag Man once again. After Hiro restrains him, Hime stabs the Paperbag Man in the head with a pitchfork.
