"Courage isn't the absence of fear. It's having the strength to protect others while your own world burns to ash." S-Rank Hunter Cha Hae-In has lived by her mother's final words for over a decade. She built a wall around her heart, became one of the strongest Hunters in South Korea, and dedicated her life to the frontlines. But a rogue dungeon break at a city museum shatters her carefully constructed reality. Stranded in an anomalous rift where the standard System's rules don't apply, Hae-In is forced to draw a mysterious, straight-edged Jikdo to save those trapped with her. The massive mana backlash leaves her physically broken and emotionally exposed, forcing her to finally confront the repressed trauma of her past-and a decades-old murder case the police lazily ruled a suicide. As a shadowy conspiracy begins to unravel around the Hunters Guild, Hae-In realizes her awakening wasn't a random cosmic lottery. She is the direct target of an ancient, demonic entity hunting the Keeper of Light. Alongside a fiercely protective uncle who has already lost too much to the dungeons, and a mysterious E-Rank turned powerhouse who refuses to leave her side, Hae-In must hunt down the monsters who stole her childhood. This isn't Sung Jin-Woo's battle. This time, the light must learn to fight its own shadows.
