After spending ten millennia scraping, clawing, and fighting his way to the absolute top of Hell, Oh Kangwoo has finally achieved the ultimate title of Demon King. But honestly? Ruling over a barren wasteland of suffering is incredibly boring, and all he really wants is to go back to Earth, eat some decent food, and sleep in a comfortable bed.

Unfortunately for him, the universe has a twisted sense of humor. When Kangwoo finally manages to tear open a portal back home, he finds his god-like demonic powers completely sealed away. To make matters worse, the cozy Earth he remembered has transformed into a chaotic, real-life MMORPG. Dimensional gates are spitting out terrifying monsters, and humans have become players who hunt them down just to survive.

If Kangwoo wants to get back his comfortable life, he has to start from absolute scratch. Armed with nothing but his ruthless combat instincts and a locked-down skill set, the former tyrant of Hell must dive headfirst into the grind. He has to level up fast, reclaim his sealed powers, and show these modern players what a real apex predator looks like. But as it turns out, navigating a monster-infested Earth might actually be a bigger pain than ruling the depths of the underworld!

Get ready for an adrenaline-fueled ride packed with epic battles, brutal strategies, and a hilarious, unapologetic protagonist who refuses to let anyone stand in his way. Can the ultimate demon conquer this new system-based world, or is Earth about to become his personal purgatory?
