Jin-Ho Kang endures life as a B-rank Hunter in a treacherous world where monsters dominate and guilds control destiny. A disastrous A-rank dungeon mission shatters his team, claiming Jin-Ho's life along with the rest. Except death never arrives. Instead, Jin-Ho awakens in an abyssal void where an ageless entity speaks—a consciousness older than time itself. The revelation transforms everything: Jin-Ho's humanity is gone, supplanted by a forbidden power never meant for mortal beings. Forgotten by the world. Yet Jin-Ho returns transformed. As a Sovereign reborn. As the Monarch of Shadows reborn. When the veil between life and death tears away, humanity will face a singular truth... The true King has awakened.
