Set in the real world, the story features two realms: the real world and the Negative World. Monsters called “Calamities” dwell in the Negative World, and the two realms occasionally intersect in completely random locations. When humans kill a Calamity from the Negative World, they have a chance to awaken a special ability called “Candlelight.” Candlelight abilities come in several types, differing only in function, not in quality. They are similar to supernatural powers.
