Life Demon, Order Demon, Knowledge Demon, Fate Demon, War Demon…When various bizarre powers invaded, the world was clearly divided into two distinct sides.Some worship them as gods, walking upon the earth as their spokespeople.Others choose to drink a glass of strong liquor on scarlet nights, and raise the hunting rifle in their hands

Penance is a prison of eternal damnation for those who go against the will of the gods.Growing up in the slums of District Nine, Nacht was like every other individual his age, struggling to survive with what little he had and blaming the capital for it. But unlike everyone else, he had been lucky. He still had a mother who cared for him deeply and did everything she could to help him succeed. However, that all changed when his mother was offered up as a sacrifice to the capital to help bolster the number of Enlightened in their arsenal.The Enlightened were elite warriors who wielded supernatural powers and served their respected clan at the cost of sacrificing an individual for the opportunity to enter Penance and be bestowed or awakening a rune, the source of their profound power.Having been exposed to the worst of humanity due to the horrific execution of his mother, Nacht developed a relentless ambition to change the world—even if it was in his own unconventional way.After performing a disgraceful ritual, Nacht is sent into Penance, where he becomes one of the Enlightened and is bestowed a mysterious power along with an insidious punishment.
