The Four Demons Chasing the Sun

In the far west, a priest in an isolated village suddenly received instructions from God one day that a great disaster would come to the world in the near future. So, under the arrangement of the sacrifice, the energetic young man in the village took the village's holy sword and embarked on a journey to save the light. The ultimate goal is the westernmost part of the continent, where the sun sets. People call it: the end of the world.
