In this desolate land, there was once a legend that on a full moon night, if the blood of the unjust dead was sprinkled on the blooming flowers, that would be the time when evil spirits would breed, and then there would be no life on the land.
Of course, from a modern perspective, it is just a story to deceive children. After all, no one has ever seen a demon, or those who have seen it have already become demons themselves.
