Han Si-woo was an overworked South Korean office worker whose mundane life ended in sudden exhaustion. Transported to a brutal dark fantasy realm, he was reborn as Leon Dragonia Lionheart. Over the course of three centuries of nonstop, blood-soaked crusade against eldritch hordes and demons, he ascended to become the holy realm's supreme champion, the legendary "Knight King." After purging evil and completing his divine vows, Leon finally earns his return ticket back to modern Earth. However, he does not return alone: the sacred gods of his realm tag along with him. Finding modern-day South Korea overrun by dimensional dungeon gates, arrogant hunters, and bureaucratic monster associations, the Knight King decides it is time to re-educate modern society on what true, uncompromising chivalry looks like.

Following the sudden appearance of dimensional Gates across the globe, modern Earth became an apocalyptic battleground overrun by demonic incursions, beast-god hordes, and dungeon breaks. Humanity managed to survive through Awakened Hunters, but centuries of commercialization and corruption degraded the noble duty of protecting the innocent into profit-driven corporate exploitation. The fundamental power system blends standard modern Hunter ranks with sacred Divine Blessings and Knightly Vows. Unlike ordinary mana, true divine miracles derive from the faith and absolute devotion channeled toward the gods of the Pantheon - including Demera (Goddess of Harvest and Life), Poma (Goddess of the Ocean and Purity), and Irmin (Goddess of Light and War). By establishing holy ground, consecrating relics, and adhering to strict knightly chivalry, mortals can ascend into legendary Grail Knights, granting them transcendental authority, divine resistance, and conceptual combat arts capable of purifying Archdemons. Gate phenomena manifest in distinct threat categories: The geopolitical landscape is dominated by the Pantheon Guild (the personal vanguard of the Lionheart Alliance), the international Hunter Associations, the corrupt demonic cults such as "One Brilliance," invasive Demon Lords from the Abyss (commanded by Archdukes such as Rakchar, Akasha, and Quay), and the militaristic Orc Federation rallying under Great Khan Murka Balrak. True victory is achieved not merely by clearing dungeons, but by spreading divine faith, cleansing the corrupted earth, and upholding unyielding chivalric honor against total annihilation. Standard / Red Gates: Dimensional rifts housing invasive beasts and demonic forces. Black Gates: Cataclysmic rifts connecting to primordial ancient domains or lost empires. Colorless Gates: Unstable dimensional anomalies connecting across alternate timelines and dying worlds.
