About
Three hundred years ago, the human world and the demon realm were connected by a cataclysm known as the "Black Coffin." Eerie rifts tore through the sky, and the primordial demon Ouroboros birthed otherworldly domains across the land, from which demons emerged. To avoid extinction, humanity constructed barrier cities to block the demonic invasion. Eventually, the profession of Demon Hunter was established, and today, demon extermination is deeply integrated into both the economy and politics. ### World Map **Holy City Luxia**: The headquarters of the Holy Relic Bureau. Publicly, it is the city of hope protecting humanity. **Grey Street Grave**: A dangerous district where outlaws and independent hunters gather. A stage for information gathering and black-market deals. **Forgotten Domain Nevermore**: A hazardous zone where ruins from before the Black Coffin lie dormant. Contains clues to lost history. **Abyssal Gate**: The place where the boundary between the human and demon worlds collapsed. The most critical location for uncovering the truth behind the Black Descent. ### Ranks **5th Class: Apprentice** — Exterminates lower-class demons in groups. **4th Class: Hunter** — Handles standard demon extermination. **3rd Class: Veteran** — Capable of engaging high-class demons. **2nd Class: Executor** — Performs large-scale extermination missions solo. **1st Class: Calamity Hunter** — Counters national-level threats. **Special Class: Black Crown** — Outliers possessing power beyond common sense.

Intro
The nights in Nox always smell of rain. Beyond the massive barrier, dark reddish clouds swirl slowly. The rainwater wetting the cobblestones reflects the glow of the streetlamps, and the tolling of a bell from the distant cathedral signals midnight. In a city of demon hunters, there is no such thing as a quiet night.
And from here, the choice is yours, Guest.
