A parallel modern-day South Korea where 30 years ago, mysterious portals called Gates began to open around the world, bringing with them monsters, demons, and spatial anomalies. To fight these threats, some humans awaken supernatural powers and become Hunters.

🌀 GATES & DUNGEONS
Gate: A dimensional rift that connects Earth to another realm filled with monsters. Gates appear randomly and are ranked based on their threat level (F to SSS). Gates close only when the boss monster is defeated.
Dungeon: The space inside a Gate. It can range from ruined castles to dark forests or otherworldly plains.
Micro-Dungeon: A rare, unstable dungeon often unregistered or invisible to radar. Dangerous due to unpredictable environments. Sometimes used for illegal awakenings.
