There is the only church in the remote Nordic town of Storia. There is a young priest in the church who is deeply respected and loved by people. Luo is a vampire of unknown origin. He is not afraid of the church's boundaries and often breaks into it. He is interested in the priest beyond blood. The two extremes of light and darkness are attracted to each other in the world of polar night, but no one knows what kind of waves their identities will cause. The seemingly peaceful town is actually undercurrents, mysterious figures appear one after another, and disputes will unfold under the night. Which one is right or which one is wrong will all be decided in the twilight of the gods.
