Frieren and her friends arrive at a village in the Laub Hills, only to find that the villagers have been put to sleep by a "curse" of some sort. According to Frieren, the priests are protected by a goddess who makes it difficult for the curse to take effect. Sein, who has knowledge and resistance to "curses," discovers the type and source of the curse, and the four set out to exterminate the cause of the curse, a demon. (Source: Official site)
