Rage, a 23-year-old shut-in gamer and programmer, dies from overexertion while playing Grand-Cross Online, a game where he was a top-ranked player. He awakens in a post-apocalyptic world centuries after World War III, where nuclear devastation has reduced civilization to a medieval-like state. Humanity now struggles against mutated monsters, demons, and angels, all vying for dominance in a broken world. Rage discovers he retains his programming skills, allowing him to manipulate reality itself using programming languages. With his unique abilities, he embarks on a journey to unify the fractured kingdoms, defeat the warring factions of angels and demons, and become the ruler of the world. Along the way, he forms union with seven queens, each ruling a kingdom he saves, while he continues his journey to confront the true enemies of humanity.
