a couple months ago I stumbled across an anime series and watched the first couple episodes. It seems I forgot to put it on my to-watch list and I cant remember the name for the life of me. It began with a priest(?) from a large empire coming to a village looking to revive a demon. To do that he needed the help of the priestess from the village. He forced her to help by threatening to kill two kids from the village. The priestess is also the deceased chiefs daughter. Her brother is the village protector. The demon is resurrected/raised and proceeds to kill the priest and saves the priestess. Afterwards the demon the priestess the brother and the demons friend (dont really remember where he came from) have to escape from a mass of skeletons. The priestess decides to marry the demon who then becomes the village chief.
Those are the major plot points I can remember. I remember also in the world of the anime there were several ages with the current one being the age of humans and the previous ages having elves etc.
There are some other minor details, let me know if more detail will help. The anime style was new in terms of drawing and animation style as far as I can remember.
